Assessing the breadth and multidisciplinarity of the conservation curriculum in the United Kingdom and Australia.

There have been repeated calls to train conservationists capable of transcending disciplinary boundaries. However, little empirical work has been done to document conservation teaching. We investigate the content taught in conservation higher education across the United Kingdom and Australia. Using data from an online survey and content analysis of module descriptions, we assess the prevalence of subject areas in 146 conservation modules and topics in 368 conservation modules and 62 conservation degrees. Biological sciences subject areas were represented in 92% of the modules, whereas social sciences subject areas only featured in 60% and humanities in 24%. Of the modules teaching biological sciences subject areas, 84% included biological sciences faculty but only 31% of the modules covering social sciences subject areas included faculty from the social sciences. Who teaches matters. The disciplinary expertise in conservation education needs to diversify to train conservationists capable of addressing conservation challenges. This requires institutional changes and support from prominent societies to promote interdisciplinary education.

Nature's contribution to poverty alleviation, human wellbeing and the SDGs.

Millions of households globally rely on uncultivated ecosystems for their livelihoods. However, much of the understanding about the broader contribution of uncultivated ecosystems to human wellbeing is still based on a series of small-scale studies due to limited availability of large-scale datasets. We pooled together 11 comparable datasets comprising 232 settlements and 10,971 households in ten low-and middle-income countries, representing forest, savanna and coastal ecosystems to analyse how uncultivated nature contributes to multi-dimensional wellbeing and how benefits from nature are distributed between households. The resulting dataset integrates secondary data on rural livelihoods, multidimensional human wellbeing, household demographics, resource tenure and social-ecological context, primarily drawing on nine existing household surveys and their associated contextual information together with selected variables, such as travel time to cities, population density, local area GDP and land use and land cover from existing global datasets. This integrated dataset has been archived with ReShare (UK Data Service) and will be useful for further analyses on nature-wellbeing relationships on its own or in combination with similar datasets.

Supporting conservationists' mental health through better working conditions.

Biodiversity conservation work can be challenging but rewarding, and both aspects have potential consequences for conservationists' mental health. Yet, little is known about patterns of mental health among conservationists and its associated workplace protective and risk factors. A better understanding might help improve working conditions, supporting conservationists' job satisfaction, productivity, and engagement, while reducing costs from staff turnover, absenteeism, and presenteeism. We surveyed 2311 conservation professionals working in 122 countries through an internet survey shared via mailing lists, social media, and other channels. We asked them about experiences of psychological distress, working conditions, and personal characteristics. Over half were from and worked in Europe and North America, and most had a university-level education, were in desk-based academic and practitioner roles, and responded in English. Heavy workload, job demands, and organizational instability were linked to higher distress, but job stability and satisfaction with one's contributions to conservation were associated with lower distress. Respondents with low dispositional and conservation-specific optimism, poor physical health, and limited social support, women, and early-career professionals were most at risk of distress in our sample. Our results flag important risk factors that employers could consider, although further research is needed among groups underrepresented in our sample. Drawing on evidence-based occupational health interventions, we suggest measures that could promote better working conditions and thus may improve conservationists' mental health and abilities to protect nature.

Mejores condiciones de trabajo para apoyar la salud mental de los conservacionistas Resumen La conservación de la biodiversidad puede ser difícil pero gratificante y ambos aspectos pueden tener consecuencias en la salud mental de los conservacionistas. Sin embargo, sabemos poco sobre la salud mental de los conservacionistas, sus patrones y los factores de protección y riesgo asociados al lugar de trabajo. Un mayor conocimiento ayudaría a mejorar las condiciones de trabajo, pues impulsaría la satisfacción laboral, la productividad y el compromiso de los conservacionistas, mientras se reducen los costos derivados de la rotación de personal, el ausentismo y el presentismo. Encuestamos a 2,311 profesionales de la conservación de 122 países con una encuesta virtual compartida por listas de correo, redes sociales y otros medios. Les preguntamos a los profesionales sobre sus experiencias de estrés psicológico, condiciones de trabajo y características personales. Más de la mitad trabajaban y procedían de Europa y Norteamérica; la mayoría respondió en inglés, contaba con estudios universitarios y actualmente desempeña funciones académicas y profesionales. La carga de trabajo excesiva, las exigencias laborales y la inestabilidad organizacional se relacionaron con un mayor estrés, mientras la estabilidad laboral y la satisfacción con la contribución propia a la conservación se asociaron con un menor estrés. En nuestra muestra, los encuestados con baja disposición y un optimismo específico hacia la conservación, mala salud física, apoyo social limitado, las mujeres y los profesionales que inician su carrera son los que corren un mayor riesgo de sufrir estrés. Nuestros resultados señalan importantes factores de riesgo que los empresarios podrían considerar, aunque es necesario seguir investigando entre los grupos menos representados en nuestra muestra. Con base en las intervenciones de salud laboral respaldadas con pruebas, sugerimos medidas que podrían promover mejores condiciones de trabajo y, así mejorar la salud mental de los conservacionistas y su capacidad para proteger la naturaleza.

What's on the horizon for community-based conservation? Emerging threats and opportunities.

Community-based conservation can support livelihoods and biodiversity, while reinforcing local and Indigenous values, cultures, and institutions. Its delivery can help address cross-cutting global challenges, such as climate change, conservation, poverty, and food security. Therefore, understanding trends in community-based conservation is pertinent to setting and implementing global goals. We undertook a horizon scan to prioritize 15 emerging threats and opportunities expected to impact the future effectiveness of community-based conservation. Topics relate to global biodiversity policy; human rights; shifting human geography; inclusion, diversity, equity, and access; conservation finance and income; and economic reforms. Our findings offer guidance on strengthening community-based conservation to achieve global environmental and development goals.

Protected areas reduce deforestation and degradation and enhance woody growth across African woodlands.

Protected areas are increasingly promoted for their capacity to sequester carbon, alongside biodiversity benefits. However, we have limited understanding of whether they are effective at reducing deforestation and degradation, or promoting vegetation growth, and the impact that this has on changes to aboveground woody carbon stocks. Here we present a new satellite radar-based map of vegetation carbon change across southern Africa's woodlands and combine this with a matching approach to assess the effect of protected areas on carbon dynamics. We show that protection has a positive effect on aboveground carbon, with stocks increasing faster in protected areas (+0.53% per year) compared to comparable lands not under protection (+0.08% per year). The positive effect of protection reflects lower rates of deforestation (-39%) and degradation (-25%), as well as a greater prevalence of vegetation growth (+12%) inside protected lands. Areas under strict protection had similar outcomes to other types of protection after controlling for differences in location, with effect scores instead varying more by country, and the level of threat. These results highlight the potential for protected areas to sequester aboveground carbon, although we caution that in some areas this may have negative impacts on biodiversity, and human wellbeing.

Quasi-experimental analysis of new mining developments as a driver of deforestation in Zambia.

Mining is a vital part of the global, and many national, economies. Mining also has the potential to drive extensive land cover change, including deforestation, with impacts reaching far from the mine itself. Understanding the amount of deforestation associated with mining is important for conservationists, governments, mining companies, and consumers, yet accurate quantification is rare. We applied statistical matching, a quasi-experimental methodology, along with Bayesian hierarchical generalized linear models to assess the impact on deforestation of new mining developments in Zambia from 2000 to present. Zambia is a globally significant producer of minerals and mining contributes ~ 10% of its gross domestic product and ~ 77% of its exports. Despite extensive deforestation in mining impacted land, we found no evidence that any of the 22 mines we analysed increased deforestation compared with matched control sites. The extent forest lost was therefore no different than would likely have happened without the mines being present due to other drivers of deforestation in Zambia. This suggests previous assessments based on correlative methodologies may overestimate the deforestation impact of mining. However, mining can have a range of impacts on society, biodiversity, and the local environment that are not captured by our analysis.

Predicting the impacts of land management for sustainable development on depression risk in a Ugandan case study.

Agricultural intensification and expanding protected areas are proposed sustainable development approaches. But, their consequences for mental health are poorly understood. This study aims to predict how forest conservation and contract farming may alter resource access and depression risk in rural Uganda. Residents (N = 695) in 11 communities in Masindi District were asked about their expectations under land management scenarios using scenario-based interviews, household characteristics and depression symptoms. Over 80% of respondents presented with a 'business-as-usual forest access' scenario expected reduced access to forest income and food over the next decade; this number climbed above 90% among 'restricted forest access' scenario respondents. Over 99% of those presented with two land access scenarios ('business-as-usual land access' and 'sugarcane expansion land access') expected wealthy households to gain land but poorer families to lose it, threatening to increase poverty and food insecurity among small-scale farmers. Bayesian structural equation modelling suggested that depression severity was positively associated with food insecurity (0.20, 95% CI = 0.12-0.28) and economic poverty (0.11, 95% CI 0.02-0.19). Decision-makers should evaluate the mental health impacts of conservation and agricultural approaches that restrict access to livelihood resources. Future research could explore opportunities to support mental health through sustainable use of nature.

Making a case for the consideration of trust, justice and power in conservation relationships.

In conservation, trust and justice are increasingly recognized as both intrinsically valuable and critical for successful socio-ecological outcomes. However, the interdependence between these concepts has not been explored. In reviewing the conservation trust scholarship, we find efforts to build trust between conservation and local actors, yet this is often conceived to incentivize local cooperation within dominant paradigms. We argue that trust-building which does not actively plan to address power asymmetries in conservation practice may inadvertently re-embed inequities, and therefore offer a justice-trust model to provide a critical analysis of conservation partnerships. We draw on environmental justice theory to better calibrate trust literature for the historical-political settings of conservation, especially in the Global South. We demonstrate that justice and trust share strong theoretical links with important practical implications for understanding relationships. We apply our justice-trust framework to multiple case-studies, exploring i) how perceptions of (in)justice can shape willingness to trust, and ii) the ways in which nature-dependent communities and marginalized conservation workers are trusted, or the conditions they give trust under, can lead to partnerships being perceived as (un)just. We argue that focusing on trust in tandem with justice can help identify power dynamics so they can be more readily addressed. This article is protected by copyright. All rights reserved.

Failure to consider trust without acknowledging perceptions of justice and power perpetuates imbalances in conservation relationships.

Balancing making a difference with making a living in the conservation sector.

Goals play important roles in people's lives because they focus attention, mobilize effort, and sustain motivation. Understanding conservationists' satisfaction with goal progress may provide insights into real-world environmental trends and flag risks to their well-being and motivation. We asked 2694 conservationists working globally how satisfied they were with progress toward goals important to them. We then explored how this satisfaction varied among groups, including demographic and occupational. Finally, we looked at respondents' experiences associated with goal-progress satisfaction. Many (94.0%) indicated that making a meaningful contribution to conservation was an important goal for them, and over half were satisfied or very satisfied in this area (52.5%). However, respondents were generally dissatisfied with progress on collective conservation goals (e.g., stopping species loss). Some groups were more likely to report dissatisfaction than others. For instance, those in conservation for longer tended to be less satisfied with collective goal progress (log odds -0.21, 95% credibility interval [CI] -0.32 to -0.10), but practitioners reported greater satisfaction (log odds 0.38, 95% CI 0.15-0.60). Likewise, those who were more optimistic in life (log odds 0.24, 95% CI 0.17-0.32), male (log odds 0.25, 95% CI 0.10-0.41), and working in conservation practice (log odds 0.25, 95% CI 0.08-0.43) reported greater satisfaction with individual goal progress. Free-text responses suggested widespread dissatisfaction with livelihood goals, particularly related to job security and adequate compensation. Although contributing to conservation appeared to be a source of satisfaction, slow goal progress in other areas--particularly around making a living--looked to be a source of distress and demotivation. Employers, funders, professional societies, and others should consider ways to help those in the sector make a difference while making a satisfactory living by, for example, prioritizing conservationists' well-being when allocating funding. This support could include avoiding exploitative practices, fostering supportive work environments, and celebrating positive outcomes.

El Balance entre Hacer una Diferencia y Ganarse la Vida en el Sector de la Conservación 21-323 Resumen Los objetivos juegan un papel importante en la vida de las personas porque enfocan la atención, movilizan esfuerzos y mantienen la motivación. El entendimiento de la satisfacción de los conservacionistas con el progreso de sus objetivos podría proporcionar información sobre las tendencias ambientales del mundo real y marcar los riesgos para su bienestar y motivaciones. Les preguntamos a 2694 conservacionistas trabajando alrededor del mundo cuán satisfechos están con el progreso hacia los objetivos que consideran más importantes. Después exploramos cómo esta satisfacción varió entre grupos, incluyendo grupos demográficos y laborales. Finalmente, observamos las experiencias de los respondientes asociadas con la satisfacción con el progreso de los objetivos. Muchos (94%) indicaron que contribuir significativamente a la conservación es un objetivo importante para ellos, y más de la mitad estuvieron satisfechos o muy satisfechos en este campo (52.5%). Sin embargo, los respondientes también mostraron una inconformidad generalizada con el progreso de los objetivos colectivos de conservación (p. ej.: detener la pérdida de especies). Algunos grupos tuvieron una mayor probabilidad de reportar inconformidades que otros grupos. Por ejemplo, aquellos con mayor tiempo en la conservación tendieron a estar menos satisfechos con el progreso de los objetivos colectivos (probabilidad log -0.21, 95% intervalo de credibilidad [IC] -0.32 a -0.10), pero los practicantes reportaron una mayor satisfacción (probabilidad log 0.38, 95% IC 0.15-0.60). De igual manera, quienes cuentan con mayor optimismo cotidiano (probabilidad log 0.24, 95% IC 0.17-0.32), son de sexo masculino (probabilidad log 0.25, 95% IC 0.10-0.41) y trabajan en la práctica de la conservación (probabilidad log 0.25, 95% IC 0.08-0.43) reportaron una mayor satisfacción con el progreso de los objetivos individuales. Las respuestas de texto libre sugirieron una inconformidad generalizada con los objetivos de sustento, particularmente los relacionados con la seguridad laboral y las compensaciones adecuadas. Aunque contribuir a la conservación parece ser una fuente de satisfacción, el progreso lento de los objetivos en otras áreas - particularmente las relacionadas con ganarse la vida - indicaba ser una fuente de angustia y desmotivación. Los empleadores, financiadores, las sociedades profesionales y demás deberían considerar maneras para ayudar a aquellos en el sector de la conservación a lograr una diferencia a la vez que se ganan la vida satisfactoriamente, por ejemplo, mediante la priorización del bienestar de los conservacionistas al momento de asignar financiamientos. Este apoyo podría incluir evitar prácticas explotadoras, fomentar ambientes de trabajo solidarios y celebrar los resultados positivos.

Effects of social networks on interventions to change conservation behavior.

Social networks are critical to the success of behavioral interventions in conservation because network processes such as information flows and social influence can enable behavior change to spread beyond a targeted group. We investigated these mechanisms in the context of a social marketing campaign to promote a wildlife poisoning hotline in Cambodia. With questionnaire surveys we measured a social network and knowledge and constructs from the theory of planned behavior at 3 points over 6 months. The intervention initially targeted ∼11% (of 365) of the village, but after 6 months ∼40% of the population was knowledgeable about the campaign. The likelihood of being knowledgeable nearly doubled with each additional knowledgeable household member. In the short term, there was also a modest, but widespread improvement in proconservation behavioral intentions, but this did not persist after 6 months. Estimates from stochastic actor-oriented models suggested that the influences of social peers, rather than knowledge, were driving changes in intention and contributed to the failure to change behavioral intention in the long term, despite lasting changes in attitudes and perceived norms. Our results point to the importance of accounting for the interaction between networks and behavior when designing conservation interventions.

Efectos de las Redes Sociales sobre las Intervenciones para Alterar el Comportamiento de Conservación Resumen Las redes sociales son de mucha importancia para el éxito de las intervenciones conductuales en la conservación porque los procesos de las redes, como los flujos de información y la influencia social, pueden facilitar que los cambios conductuales lleguen más allá del grupo al que se desea modificar su comportamiento. Investigamos estos mecanismos dentro del contexto de una campaña de mercadotecnia social para promover una línea directa de atención al envenenamiento de fauna en Camboya. Mediante encuestas, medimos una red social y el conocimiento y las construcciones a partir de la teoría del comportamiento planeado en tres puntos a lo largo de seis meses. La intervención inicialmente se enfocó en ∼11% (de 365) de la aldea, pero después de seis meses ∼40% de la población tenía conocimiento sobre la campaña. La probabilidad de tener conocimiento sobre la campaña casi se duplicó con cada miembro adicional del hogar que adquiría dicho conocimiento. A corto plazo, también hubo una mejora modesta pero extensa de las intenciones conductuales en pro de la conservación, pero esto no continuó una vez transcurridos los seis meses. Las estimaciones de los modelos estocásticos orientados hacia los actores sugirieron que la influencia de los pares sociales, y no el conocimiento, era la causante de los cambios en la intención y contribuyó al fracaso en la intención de cambio conductual a largo plazo, a pesar de los cambios duraderos en las actitudes y las normas percibidas. Nuestros resultados apuntan hacia la importancia de la consideración de las interacciones entre las redes sociales y el comportamiento cuando se diseñan las intervenciones de conservación.

The bean method as a tool to measure sensitive behavior.

Conservationists need to measure human behavior to guide decisions and evaluate their impact. However, activities can be misreported and reporting accuracy may change following conservation interventions, making it hard to verify any apparent changes. Techniques for asking sensitive questions are increasingly integrated into survey designs to improve data quality, but some can be costly or hard for nonexperts to implement. We demonstrate a straightforward, low-cost approach, the bean method in which respondents give anonymous answers by adding a colored bean to a jar to denote a yes or no response. We applied the bean method to measure wild-meat hunting and trading over 2 years at a conservation-project (hunting reduction) site in Gola Forest, Liberia. We extended the technique to accommodate questions about hunting and meat-selling frequency. We compared responses given using the bean method and direct questioning for groups that did and did not participate in conservation interventions. Results from the bean method corresponded to those from direct questioning, and there was no indication of change in question sensitivity following conservation interventions. Estimates from both methods indicated that wild-meat trading decreased in project and nonproject households (from 36% to 20%) and that hunting decreased in 1 project group (38-28%). Where inconsistent answers were given (2-6% of respondents), differences were in both directions and were most likely attributable to measurement error. The bean method was quick and straightforward to administer in a low-literacy setting. We showed how it can be modified for answers of more than 2 categories and consider it a valuable tool that could be adapted for a wide range of conservation settings.

El Método del Frijol como Herramienta para Medir los Comportamientos Sensibles Resumen Los conservacionistas necesitan medir el comportamiento humano para dirigir las decisiones tomadas y evaluar su impacto. Sin embargo, las actividades pueden estar mal reportadas y la fiabilidad de los reportes puede cambiar después de implementadas las intervenciones de conservación, lo cual complica la verificación de cualquier cambio aparente. Las técnicas para realizar preguntas sensibles cada vez se integran más al diseño de los censos y así mejorar la calidad de los datos, aunque algunas pueden ser caras o complicadas de implementar para quienes no son expertos. Demostramos una estrategia directa y de bajo costo, el método del frijol, en el cual los respondientes proporcionan respuestas anónimas al añadir un frijol pintado dentro de un frasco y así indicar una respuesta de sí o no. Aplicamos el método del frijol para medir la cacería y el mercado de carne silvestre durante dos años dentro de un proyecto de conservación (reducción de la cacería) en el bosque Gola, Liberia. Extendimos la técnica para acomodar preguntas sobre la frecuencia de la caza y la venta de carne. Comparamos las respuestas dadas usando el método del frijol y aquellas dadas en el cuestionamiento directo a grupos que participaban o no en las intervenciones de conservación. Los resultados obtenidos con el método del frijol correspondieron a aquellos obtenidos con los cuestionamientos directos y no hubo indicación de cambios en la sensibilidad de las preguntas después de las intervenciones de conservación. Las estimaciones de ambos métodos indicaron que el mercado de carne silvestre disminuyó en los hogares participantes o no en el proyecto (de 36% a 20%) y que la cacería disminuyó en un grupo del proyecto (38% a 28%). En donde se dieron respuestas contradictorias (2-6% de los respondientes), las diferencias fueron en ambas direcciones y en su mayoría probablemente eran atribuibles al error en la medición. El método del frijol fue rápido y directo para administrarlo en un ambiente de bajo alfabetismo. Mostramos cómo puede modificarse para respuestas con más de dos categorías y lo consideramos una herramienta valiosa que podría adaptarse para una gama amplia de escenarios de conservación.

Predicting intervention priorities for wildlife conflicts.

There is growing interest in developing effective interventions to manage socially and environmentally damaging conservation conflicts. There are a variety of intervention strategies that can be applied in various contexts, but the reasons one type of intervention is chosen over another remain underexplored. We surveyed conservation researchers and practitioners (n = 427) to explore how characteristics of conflicts and characteristics of decision makers influence recommendations to alleviate conservation conflict. Using a full-factorial design, we experimentally manipulated 3 aspects of the descriptions of 8 different wildlife-conflict scenarios (development status of the conflict country, conflict framing, and legality of killing wild animals) and recorded which of 5 intervention types (wildlife impact reduction, awareness, enforcement, economic incentives, or stakeholder engagement) respondents prioritized. We also recorded information on respondents' demographic and disciplinary backgrounds. Stakeholder-based interventions were recommended most often in the survey and in written feedback. However, when we fitted multinomial mixed logit models with fully completed scenario responses (n = 411), recommendations were influenced by small changes in the details of conflict and differed according to respondent characteristics. Enforcement and awareness interventions were prioritized relatively more for conflicts in more highly developed nations and by respondents with more natural science backgrounds and relatively less experience with conflict. Contrastingly, economic interventions were prioritized more when wildlife killing was described as illegal. Age, gender, and development status of the respondent's home country also predicted some intervention decisions. Further, interrogating the influences shaping conservation decision making will further helps in the development of evidence-informed interventions.

Predicción de Prioridades de Intervención para Conflictos de Vida Silvestre Resumen Existe un creciente interés en desarrollar intervenciones efectivas para gestionar conflictos de conservación social y ambientalmente dañinos. Hay una variedad de estrategias de intervención que pueden ser aplicadas en diversos contextos, pero las razones por las que se selecciona un tipo de estrategia han sido poco exploradas. Encuestamos a investigadores y a profesionales de la conservación (n = 427) para explorar cómo influyen las características tanto de los conflictos como de los tomadores de decisiones en las recomendaciones para mitigar conflictos de conservación. Mediante un diseño factorial completo, manipulamos experimentalmente 3 aspectos de las descripciones de 8 escenarios de conflictos de vida silvestre diferentes (nivel de desarrollo del país en conflicto, encuadre del conflicto y legalidad de la matanza de animales silvestres) y registramos la priorización de 5 tipos de intervención (disminución del impacto de la vida silvestre, sensibilización, cumplimiento, incentivos económicos o participación de las partes interesadas) por los encuestados. También registramos información sobre los antecedentes demográficos y disciplinares de los encuestados. Las intervenciones basadas en las partes interesadas fueron recomendadas con mayor frecuencia en las encuestas y en la retroalimentación escrita. Sin embargo, cuando ajustamos los modelos logit mixtos multinomiales con repuestas de escenarios completos (n = 411), las recomendaciones se vieron influenciadas por pequeños cambios en los detalles del conflicto y diferían según las características de los encuestados. Las intervenciones de cumplimiento y sensibilización fueron relativamente más priorizadas para conflictos en naciones altamente desarrolladas y por encuestados con formación en ciencias naturales y relativamente menos experiencia con conflictos. En contraste, las intervenciones económicas fueron más priorizadas cuando la matanza de vida silvestre era descrita como ilegal. La edad, el género y nivel de desarrollo del país de origen del encuestado también predijeron algunas decisiones de intervención. Una mayor profundización en las influencias que configuran la toma de decisiones en conservación promoverá el desarrollo de intervenciones basadas en evidencias.

Improving Environmental Interventions by Understanding Information Flows.

Conservationists are increasingly interested in changing human behaviour. One understudied aspect of such interventions is information flow. Different patterns of interpersonal communication and social structures within communities influence the adoption of behavioural changes through social influence and social reinforcement. Understanding the structure of information flow in a group, using tools such as social network analysis, can therefore offer important insights for interventions. For example, communications may be targeted to highly connected opinion leaders to leverage their influence, or communication may be facilitated between distinct subgroups to promote peer learning. Incorporating these approaches into conservation interventions can promote more effective behaviour change. This review introduces conservation researchers and practitioners to key concepts underpinning information flows for interventions targeting networks of individuals.

Integrating models of human behaviour between the individual and population levels to inform conservation interventions.

Conservation takes place within social-ecological systems, and many conservation interventions aim to influence human behaviour in order to push these systems towards sustainability. Predictive models of human behaviour are potentially powerful tools to support these interventions. This is particularly true if the models can link the attributes and behaviour of individuals with the dynamics of the social and environmental systems within which they operate. Here we explore this potential by showing how combining two modelling approaches (social network analysis, SNA, and agent-based modelling, ABM) could lead to more robust insights into a particular type of conservation intervention. We use our simple model, which simulates knowledge of ranger patrols through a hunting community and is based on empirical data from a Cambodian protected area, to highlight the complex, context-dependent nature of outcomes of information-sharing interventions, depending both on the configuration of the network and the attributes of the agents. We conclude by reflecting that both SNA and ABM, and many other modelling tools, are still too compartmentalized in application, either in ecology or social science, despite the strong methodological and conceptual parallels between their uses in different disciplines. Even a greater sharing of methods between disciplines is insufficient, however; given the impact of conservation on both the social and ecological aspects of systems (and vice versa), a fully integrated approach is needed, combining both the modelling approaches and the disciplinary insights of ecology and social science. This article is part of the theme issue 'Linking behaviour to dynamics of populations and communities: application of novel approaches in behavioural ecology to conservation'.

Audience segmentation to improve targeting of conservation interventions for hunters.

Audience segmentation could help improve the effectiveness of conservation interventions. Marketers use audience segmentation to define the target audience of a campaign. The technique involves subdividing a general population into groups that share similar profiles, such as sociodemographic or behavioral characteristics. Interventions are then designed to target the group or groups of interest. We explored the potential of audience segmentation for use in defining conservation target groups with a case study of hunters in Liberia. Using 2 data sets describing households (n = 476) and hunters (n = 205), we applied a clustering method in which infinite binomial mixture models group hunters and households according to livelihood and behavior variables and a simple method to define target groups based on hunting impact (hunting households and high-impact hunters). Clusters of hunters and households differed in their experiences with confiscation of catch at roadblocks and participation in livelihood-support programs, indicating that these interventions operate unevenly across subsets of the population. By contrast, the simple method masked these insights because profiles of hunting households and high-impact hunters were similar to those of the general population. Clustering results could be used to guide the development of livelihood and regulatory interventions. For example, a commonly promoted agricultural activity, cocoa farming, was practiced by only 2% (out of 87) of the largest hunter cluster of nonlocal gun hunters but was prevalent among local trappers, suggesting that assistance aimed at cocoa farmers is less appropriate for the former group. Our results support the use of audience segmentation across multiple variables to improve targeted intervention designs in conservation.

Segmentación del Público para Mejorar la Focalización de las Intervenciones de Conservación para los Cazadores Resumen La segmentación del público podría ayudar a mejorar la efectividad de las intervenciones de conservación. Los publicistas utilizan la segmentación del público para definir al público focal de una campaña. La técnica incluye la subdivisión de una población general en grupos que comparten perfiles similares, como las características socio-demográficas o de comportamiento. Después se diseñan las intervenciones para enfocarse en el grupo o los grupos de interés. Exploramos el potencial de la segmentación del público en el uso de la definición de grupos con objetivos de conservación usando el estudio de caso de los cazadores en Liberia. Con dos conjuntos de datos de descripciones de los hogares (n = 476) y de los cazadores (n = 205) aplicamos un método de agrupación en el cual los modelos de mezcla binomial infinita agruparon a los cazadores y a los hogares de acuerdo a las variables de sustento y de comportamiento. También aplicamos un método simple para definir los grupos focales con base en el impacto de la caza (hogares de cazadores y cazadores de alto impacto). Los grupos de cazadores y de hogares difirieron en experiencias con la confiscación de la caza en retenes y en participación dentro de programas de apoyo al sustento, lo que indica que estas intervenciones operan disparejamente en los subconjuntos de la población. En contraste, el método simple enmascaró estas percepciones ya que los perfiles de los hogares de cazadores y de los cazadores de alto impacto fueron similares a los de la población general. La agrupación de los resultados podría usarse para guiar el desarrollo del sustento y de las intervenciones regulatorias. Por ejemplo, el cultivo de cacao, una actividad agrícola que se promueve frecuentemente, sólo lo practicaba el 2% (de 87) del mayor grupo de cazadores de los cazadores armados no locales, pero fue prevaleciente entre los trampeadores locales, lo que sugiere que la asistencia enfocada hacia los cultivadores de cacao es menos apropiada para el primer grupo. Nuestros resultados respaldan el uso de la segmentación del público en múltiples variables para mejorar los diseños de intervenciones focalizadas en la conservación.

Detecting deterrence from patrol data.

The threat posed to protected areas by the illegal killing of wildlife is countered principally by ranger patrols that aim to detect and deter potential offenders. Deterring poaching is a fundamental conservation objective, but its achievement is difficult to identify, especially when the prime source of information comes in the form of the patrols' own records, which inevitably contain biases. The most common metric of deterrence is a plot of illegal activities detected per unit of patrol effort (CPUE) against patrol effort (CPUE-E). We devised a simple, mechanistic model of law breaking and law enforcement in which we simulated deterrence alongside exogenous changes in the frequency of offences under different temporal patterns of enforcement effort. The CPUE-E plots were not reliable indicators of deterrence. However, plots of change in CPUE over change in effort (ΔCPUE-ΔE) reliably identified deterrence, regardless of the temporal distribution of effort or any exogenous change in illegal activity levels as long as the time lag between patrol effort and subsequent behavioral change among offenders was approximately known. The ΔCPUE-ΔE plots offered a robust, simple metric for monitoring patrol effectiveness; were no more conceptually complicated than the basic CPUE-E plots; and required no specialist knowledge or software to produce. Our findings demonstrate the need to account for temporal autocorrelation in patrol data and to consider appropriate (and poaching-activity-specific) intervals for aggregation. They also reveal important gaps in understanding of deterrence in this context, especially the mechanisms by which it occurs. In practical applications, we recommend the use of ΔCPUE-ΔE plots in preference to other basic metrics and advise that deterrence should be suspected only if there is a clear negative slope. Distinct types of illegal activity should not be grouped together for analysis, especially if the signs of their occurrence have different persistence times in the environment.

Detección de la Disuasión a Partir de Datos de Patrullaje Resumen La amenaza que representa la caza ilegal de fauna para las áreas protegidas está contrarrestada principalmente por las patrullas de guardias que buscan detectar y disuadir a los delincuentes potenciales. La disuasión de la caza furtiva es un objetivo fundamental de la conservación, pero es difícil identificar cuándo se logra, especialmente cuando la fuente principal de información proviene de los propios registros de las patrullas, que inevitablemente contiene sesgos. La medida más común de la disuasión es una parcela de actividades ilegales detectadas por unidad de esfuerzo de patrullaje (CPUE, en inglés) contra el esfuerzo de patrullaje (CPUE-E, en inglés). Diseñamos un modelo simple y mecánico del rompimiento y aplicación de la ley en el cual simulamos la disuasión junto con cambios exógenos en la frecuencia de ofensas bajo diferentes patrones temporales del esfuerzo de aplicación. Las parcelas de CPUE-E no fueron indicadores confiables de la disuasión. Sin embargo, las parcelas de cambio de CPUE sobre cambio en el esfuerzo (ΔCPUE-ΔE) identificaron con seguridad la disuasión sin importar la distribución temporal del esfuerzo o cualquier cambio exógeno en los niveles de actividad ilegal siempre y cuando el retraso en el tiempo entre el esfuerzo de patrullaje y el cambio en comportamiento subsecuente entre los delincuentes se conocía con cierta aproximación. Las parcelas de ΔCPUE-ΔE ofrecieron una medida simple y sólida para el monitoreo de la efectividad del patrullaje; no fueron más complicadas conceptualmente que las parcelas básicas de CPUE-E; y no requirieron de conocimiento de especialistas o algún software para producir. Nuestros hallazgos demuestran la necesidad de dar cuenta de la autocorrelación temporal en los datos de patrullaje y de considerar intervalos apropiados (y específicos a la actividad de caza furtiva) para su agregación. Nuestros hallazgos también revelan vacíos importantes en el entendimiento de la disuasión en este contexto, especialmente para los mecanismos mediante los cuales ocurre. En las aplicaciones prácticas recomendamos el uso de parcelas de ΔCPUE-ΔE por encima de otras medidas básicas y recomendamos que se sospeche de la disuasión sólo si existe una clara pendiente negativa. No se deben agrupar diferentes tipos de actividades ilegales para su análisis, especialmente si las señales de su ocurrencia tienen diferentes momentos de persistencia en el ambiente.

A quasi-experimental study of impacts of Tanzania's wildlife management areas on rural livelihoods and wealth.

Since the 2000s, Tanzania's natural resource management policy has emphasised Wildlife Management Areas (WMAs), designed to promote wildlife and biodiversity conservation, poverty alleviation and rural development. We carried out a quasi-experimental impact evaluation of social impacts of WMAs, collecting data from 24 villages participating in 6 different WMAs across two geographical regions, and 18 statistically matched control villages. Across these 42 villages, we collected participatory wealth ranking data for 13,578 households. Using this as our sampling frame, we conducted questionnaire surveys with a stratified sample of 1,924 household heads and 945 household heads' wives. All data were collected in 2014/15, with a subset of questions devoted to respondents' recall on conditions that existed in 2007, when first WMAs became operational. Questions addressed household demographics, land and livestock assets, resource use, income-generating activities and portfolios, participation in natural resource management decision-making, benefits and costs of conservation. Datasets permit research on livelihood and wealth trajectories, and social impacts, costs and benefits of conservation interventions in the context of community-based natural resource management.

Games as Tools to Address Conservation Conflicts.

Conservation conflicts represent complex multilayered problems that are challenging to study. We explore the utility of theoretical, experimental, and constructivist approaches to games to help to understand and manage these challenges. We show how these approaches can help to develop theory, understand patterns in conflict, and highlight potentially effective management solutions. The choice of approach should be guided by the research question and by whether the focus is on testing hypotheses, predicting behaviour, or engaging stakeholders. Games provide an exciting opportunity to help to unravel the complexity in conflicts, while researchers need an awareness of the limitations and ethical constraints involved. Given the opportunities, this field will benefit from greater investment and development.

Exploring differences in stakeholders' perceptions of illegal bird trapping in Cyprus.

BACKGROUND: Cyprus is recognised as a hotspot for illegal bird trapping in the Mediterranean basin. A consumer demand for the Eurasian blackcap (Sylvia atricapilla) is driving the use of non-selective trapping methods, resulting in the indiscriminate killing of millions of migratory birds. Efforts to tackle the issue have so far been characterised mostly by a top-down approach, focusing on legislation and enforcement. However, trapping levels are not decreasing and conflict between stakeholder groups is intensifying. METHODS: To understand why efforts to stop illegal bird trapping have not been effective, we used semi-structured interviews to interview 18 local bird trappers and nine representatives from the pertinent environmental non-governmental organisations (NGOs) and the governmental agencies responsible for enforcing the legislation. RESULTS: We found distinct differences between the views of the local trapping community and the environmental NGOs, particularly on why trapping is occurring and its impact on the avifauna. This disparity has contributed to misrepresentations of both sides and a high degree of conflict, which is potentially proving counterproductive to conservation interventions. In addition, it appears that trappers are a heterogeneous group, likely driven by various motivations besides profit. CONCLUSION: We argue that stakeholders interested in reducing illegal bird trapping need to develop anti-poaching strategies that aim at minimising the disparity in the views, and subsequently the conflict, acknowledging also that trappers are not a homogenous group, as often treated.
