RESUMO

This research article investigates the intricate interplay between climate change, global sea level rise (SLR), and the impacts of sea level rise on the coastal regions of India. Through an interdisciplinary approach, this paper provides an overview of the global consequences of SLR on coastal communities, exploring economic, social, and environmental impacts on agriculture, communities, and coastal areas. The study examines the displacement of communities and its impact on food security, infrastructure, tourism, and ecological loss based on a comprehensive literature review. This paper emphasizes the sustainable preservation of coastal ecosystems and the development of climate-resilient infrastructure. This research aims to offer a detailed understanding of the evolving landscape of coastal livelihoods, providing valuable insights for adaptive strategies, policy formulation, and sustainable development. Ultimately, this article contributes to the scientific discourse by shedding light on the complex dynamics between climate change, SLR, and coastal communities, guiding efforts toward a resilient and sustainable future. The insights are drawn from secondary data resources, including books, scholarly journals, and reports from organizations such as the IPCC and NOAA. Based on a thorough review of the relevant literature, it critically examines the existing and potential consequences of sea level rise induced by climate change.

RESUMO

The Ashanti region in Ghana, abundant in natural resources such as forests and vegetation biomes, significantly supports the livelihoods of a significant portion of the population. The sustainable management of forest resources remains a significant challenge to achieving environmental and economic growth and poverty alleviation. The study aims to identify the drivers of deforestation and assess its impact on the livelihoods of the poor and vulnerable communities in the Ashanti region. The study utilized qualitative and space-based data to examine the patterns of vegetation cover and deforestation from 2000 to 2020. The results revealed moderate to sparse vegetation in Ashanti from 2002, 2005, 2011, 2015, 2017, and 2018, with no vegetation in the northcentral part, attributed to climate change, agricultural practices, government policies, and deforestation-related disasters. The study found a significant correlation (R² = 0.8197) between years and deforestation areas, especially in 2018 at around 16,000 Sqkm, indicating an exponential increase with severe implications for sustainable livelihoods. Much of these changes were reflected in 2020 with a high peak of deforestation towards the southeastern parts of the region. Additionally, the results show that the poor groups are not passive actors but are actively involved in identifying systems and processes through which to build their adaptive capacity and resilience to environmental and climate change-induced changes. The findings provide evidence-based and all-inclusive approaches that would encourage vulnerable and marginalized groups to participate in the co-production and co-creation of policies and strategies. This outcome is geared towards transformative and sustainable communities while ensuring efficient and effective response and recovery capacities of deforested lands.

RESUMO

Background: Persons with disabilities are more likely to have poorer livelihood outcomes, including food insecurity. Inequalities are heightened for young women with disabilities, especially in times of crisis. Objectives: To understand the livelihood experience of young South African women with and without disabilities during the coronavirus pandemic (COVID-19). Method: We conducted a longitudinal study with 72 young women with and without disabilities enrolled in tertiary institutions in eThekwini, South Africa. We undertook a series of in-depth interviews collecting quantitative and qualitative data, prompting participants' experiences during the COVID-19 pandemic, including living arrangements, impact on education, access to resources and food security. Results: Participants reported livelihood changes related to living arrangements, education, income, and social connectedness during the pandemic. Social grants (old-age pension, child support, disability grant) and student stipends were critical financial resources to ensure food security. Participants with disabilities were more likely to experience food insecurities and moderate hunger, with their households having less access to mitigating resources such as land or livestock. Deaf participants also reported social isolation. Conclusion: The study shows that social protection mechanisms mitigated the financial impact of the lockdown for all recipients but that participants with disabilities still struggled more than others to ensure food security. These additional challenges may be related to pre-existing inequalities, with participants with disabilities and their households having less access to natural resources and financial stability. Contribution: This paper focuses on young women with and without disabilities and provides insight into the similarities and differences in their experiences.

RESUMO

BACKGROUND: The COVID-19 pandemic has had widespread health, social and economic impacts worldwide. In many contexts, it has likely exacerbated existing inequalities. OBJECTIVE: This study compares the economic impacts of the COVID-19 pandemic amongst people with and without disabilities in Viet Nam. METHODS: A telephone survey was conducted in the three largest cities of Viet Nam (Da Nang, Ha Noi, and Ho Chi Minh City) between December 2021 and January 2022. Participants were recruited through convenience sampling (n = 898; 479 people with disabilities; 419 without). The survey collected data on livelihoods, employment, household economic security, and access to social protection and assistance. RESULTS: People with disabilities were three times more likely to have stopped working completely (PR: 2.8, 95 % CI: 2.0-4.0), 30 % more likely to report reduced earnings (PR: 1.3, 95 % CI: 1.2-1.5), twice as likely to report severe impacts on household finances (PR: 1.9, 95 % CI: 1.6-2.3) and three times more likely to report severe impacts on household food security (PR: 3.2, 95 % CI: 2.3-4.6) since the onset of the pandemic. Amongst people with disabilities, informal workers were particularly negatively affected. Households with members with disabilities were more likely to receive some types of COVID-19-related assistance (e.g. financial or food aid), but less likely to be enrolled in social insurance. CONCLUSIONS: Urgent and inclusive responses are necessary during crises to address the unique challenges faced by people with disabilities. Implementing comprehensive social protection measures is crucial to narrowing disparities, and maintaining well-being and economic security during shocks such as COVID-19.

RESUMO

Decades of illegal hunting (poaching) have adversely affected wildlife populations and thereby limited sustainable wildlife conservation in the Luangwa Valley, Zambia. Despite intervention efforts to address the problem, the illegal hunting of wildlife has persisted. Therefore, this study was conducted to understand the persistence of illegal hunting by investigating the drivers of poaching and intervention measures using a mixed methods approach. Stratified random sampling was used to collect data from 346 respondents through structured questionnaires. Purposive sampling was used to collect data through nine focus group discussions and three in-depth interviews with experts. The study revealed that persistent illegal hunting was mainly driven by people's critical need for survival and sustaining their livelihoods and not by inadequate law enforcement as presumed by resource managers. Although law enforcement was the most prevalent intervention measure, it did not deter local illegal hunters because their main motivations for poaching were not effectively addressed. The key implication of these findings is that where the illegal harvesting of natural resources in protected areas by local resource users is driven by people's critical need for survival and a livelihood, which is ineffectively addressed, illegal harvesting may persist even with increased law enforcement. This study provides empirical evidence, novel conceptual knowledge and an understanding of how prevalent drivers of poaching and other factors may have influenced persistent illegal hunting in the Luangwa Valley.

RESUMO

While Moringa oleifera Lam. is gaining importance in Africa, especially sub-Saharan Africa, it is unclear whether research is following the quick pace of its development on the continent. Therefore, this article analyzes the landscape of research dealing with moringa in Africa. This systematic review draws upon 299 eligible articles identified through a search carried out on the Web of Science in April 2023. Research on M. oleifera is rather recent in Africa but interest is increasing among scholars. While the research field is multidisciplinary and cross-sectoral, the literature seems to focus on biological and environmental sciences. Moreover, research is performed mainly in South Africa, Nigeria, Egypt, and Ghana. The analysis suggests a significant potential contribution of moringa to food security and nutrition, climate change mitigation/adaptation, farming systems resilience, and livelihoods. Its versatility and diverse applications and uses make moringa particularly interesting for developing countries, such as African ones. However, this review also underscores some factors hindering its development. Therefore, there is a need to strengthen research on moringa to unlock its potential in Africa. Investments in research, innovation, and development can help address the many challenges that Africa faces and contribute to the transition towards sustainable and resilient food systems.

RESUMO

To achieve sustainable shark fisheries, it is key to understand not only the biological drivers and environmental consequences of overfishing, but also the social and economic drivers of fisher behavior. The extinction risk of sharks is highest in coastal tropical waters, where small-scale fisheries are most prevalent. Small-scale fisheries provide a critical source of economic and nutritional security to coastal communities, and these fishers are among the most vulnerable social and economic groups. We used Kenya's and Zanzibar's small-scale shark fisheries, which are illustrative of the many data-poor, small-scale shark fisheries worldwide, as case studies to explore the relationship between extinction risk and the economic and nutritional value of sharks. To achieve this, we combined existing data on shark landings, extinction risk, and nutritional value with sales data at 16 key landing sites and information from interviews with 476 fishers. Shark fisheries were an important source of economic and nutritional security, valued at >US$4 million annually and providing enough nutrition for tens of thousands of people. Economically and nutritionally, catches were dominated by threatened species (72.7% and 64.6-89.7%, respectively). The most economically valuable species were large and slow to reproduce (e.g. mobulid rays, wedgefish, and bull, silky, and mako sharks) and therefore more likely to be threatened with extinction. Given the financial incentive and intensive fishing pressure, small-scale fisheries are undoubtedly major contributors to the decline of threatened coastal shark species. In the absence of effective fisheries management and enforcement, we argue that within small-scale fisheries the conditions exist for an economically incentivized feedback loop in which vulnerable fishers are driven to persistently overfish vulnerable and declining shark species. To protect these species from extinction, this feedback loop must be broken.


Conexión entre el riesgo de extinción y el valor nutricional de los tiburones en las pesquerías a pequeña escala Resumen Para lograr la sustentabilidad de las pesquerías de tiburones se deben entender los factores ecológicos y las consecuencias ambientales de la sobrepesca, así como los factores sociales y económicos del comportamiento del pescador. El riesgo de extinción de los tiburones es mucho mayor en las aguas tropicales costeras, en donde son más frecuentes las pesquerías a pequeña escala. Las pesquerías a pequeña escala, que además se encuentran entre los grupos con mayor vulnerabilidad social y económica, proporcionan una fuente importante de seguridad económica y nutricional para las comunidades costeras. Usamos las pesquerías de Kenia y Zanzíbar, las cuales representan muy bien a muchas de las pequeñas pesquerías de tiburones con deficiencia de datos, como estudios de caso para explorar la relación entre el riesgo de extinción y el valor económico y nutricional de los tiburones. Para lograr esto, combinamos los datos ya existentes de desembarques de tiburones, riesgo de extinción y valor nutricional con la información de ventas en 16 sitios clave de desembarque e información de las entrevistas a 476 pescadores. Las pesquerías de tiburones son una fuente importante de seguridad alimentaria y económica, valorada en más de US$4 millones anuales y que proporciona suficiente alimentación para miles de personas. En cuanto a la economía y la alimentación, las capturas estuvieron dominadas por especies amenazadas (72.7% y 64.6­89.7%, respectivamente). Las especies con mayor valor económico eran aquellas de gran tamaño y lenta reproducción, y, por lo tanto, con mayor probabilidad de estar en peligro de extinción. A causa del incentivo económico y la presión intensa de pesca, las pesquerías pequeñas sin duda son uno de los principales contribuyentes a la declinación de especies amenazadas de tiburones en las costas. Ya que no hay una aplicación ni un manejo efectivos de las pesquerías, argumentamos que en las pequeñas pesquerías existen las condiciones para un bucle de retroalimentación con incentivación económica en el que los pescadores vulnerables con frecuencia necesitan sobre pescar las especies de tiburones vulnerables y en declinación. Para proteger a estas especies de la extinción, este bucle de retroalimentación debe romperse.

RESUMO

With limited national financing for conservation, there is an increasing interest in using biodiversity offset funds to strengthen protected area management. Offsetting measures can potentially be used in the restoration of degraded protected areas. However, there are concerns related to the uncertainty of restoration outcomes and time-lags before the expected benefits can be observed. Using a case of the Gangu Central Forest Reserve in central Uganda, we contribute empirical findings showing the potential and limitations of biodiversity offsetting by means of the restoration of a degraded forest reserve. We use forest cover change analysis and community surveys to determine forest changes after eight years of offset implementation, and forest inventories to analyse the current forest structure and composition to ascertain taxonomic diversity recovery. The results revealed that biodiversity offsetting led to a 21% increase in Tropical High Forest cover, and enhanced restoration of forest species composition and diversity. However, attaining permanence of the restoration benefits requires the regulation of community forest resource access and use. Strengthening forest management capacity to monitor the offset sites and compensating impacted communities for foregone forest resource benefits are crucial for the successful implementation of biodiversity offsets.

RESUMO

In the Solomon Islands and around the Pacific there is commonly a disconnect between government priorities for economic development through resource extraction and community aspirations for local resource management, conservation, and alternative pathways to livelihoods development, which includes tourism. Nowhere is this disconnect more stark than in communities on Rennell Island, within the region's oldest inscribed World Heritage area. These communities have so far resisted extractive industry development but have not yet benefited from inscription. Alternative livelihood opportunities compatible with a conservation economy are a priority. Our research objective was to explore community aspirations and priorities. We used Q-methodology to reveal discourses associated with conservation, livelihoods generation, and drivers of well-being and then evaluated these aspirations in scenarios in a socio-ecological system. We revealed three factors, each aligned with conservation and tourism development with clear opposition to extractive industries. Key differences focussed on immediate personal circumstances, attachment to kastom, and food and water security. Our research points to clear support for the area's continued conservation and for livelihood pathways that might secure this but low capacity to pursue this. Notwithstanding, the communities' patience is wearing thin and there is growing cynicism about the role of World Heritage protection as a route towards livelihoods development.

RESUMO

This study delves into the profound impact of climate change on agriculture in Ethiopia, particularly the vulnerabilities faced by smallholder farmers and the resulting implications for poverty. Focusing on three distinct agroecologies, namely: highland, midland, and lowland zones. The study employed a robust methodology, combining a cross-sectional survey, spatial-temporal trend analysis using GIS, and the development of an overall vulnerability index through the balanced weighted average method. The study, encompassing 646 households, combines data from a variety of sources and analytical tools like the vulnerability index, ArcGIS 10.8, and ERDA's IMAGINE 2015. Utilizing the LVI-IPCC scale, the study shows that climate change is an immediate vulnerability in all agroecological zones. It identifies highland areas as the most sensitive and exposed regions, while lowland households are found to be the most vulnerable in terms of overall vulnerabilities. The research reveals specific challenges faced by communities, such as inadequate health facilities and insufficient food and water supplies in both highland and lowland agroecosystems. Additionally, our investigation has observed a significant alteration in land use practices, specifically the shift from communal grazing land to private cultivation and plantations, emphasizing eucalyptus. This alteration enhances the ecosystem's vulnerability to climate disturbances. The study suggests targeted interventions, such as advocating for sustainable land-use practices, afforestation, and adopting climate-smart agriculture practices. It is important to implement policy measures that prioritize conserving and restoring shrubland, grazing land, and natural forests to ensure both long-term socio-economic and ecosystem resilience. The study's nuanced insights are instrumental in understanding the diverse challenges posed by climate change in Ethiopian agriculture, supporting informed policymaking and sustainable interventions.

RESUMO

Rural and agricultural communities' adaptation to climate change has gained significant attention owing to many countries' vulnerability to climate change risks. A similar trend has been witnessed in South Asia, a highly climate-vulnerable region, where research has grown dramatically considering the agriculture sector's vulnerability to climate-induced disasters. However, little attention has been paid to the adaptation of the livelihoods of rural households. This research, therefore, takes the case of Pakistan to explore livelihood adaptation strategies of rural households to climate change and investigate the factors that expedite or halt the adoption of livelihood diversification strategies. A multistage sampling design is used in this research, where 480 rural households from the Punjab province of Pakistan were selected and interviewed using stratified and random sampling approaches. A multivariate probit (MVP) regression model is employed to analyze the factors affecting households' adoption of livelihood adaptation strategies. The results show that besides adaptation of agronomic operations (agricultural adaptation strategies), rural households in the study area employed a wide range of strategies to adapt their livelihoods to climate change. These strategies include poultry and livestock farming, value addition of farm produce, trading of animals and farm commodities, small businesses (shops, etc.), daily wage labor, horticultural crop farming, and non-farming jobs. The estimates of the MVP model revealed that respondents' education, household size, income, access to a credit facility, access to farm advisory services, and access to climate forecasts have significantly influenced the choice of livelihood adaptation strategies. Based on these findings, this research recommends that the authorities should make efforts to improve farmers' understanding of the adaptation of climate change risks and educate them to adopt multiple livelihood options to improve the resilience of their livelihoods to climate-induced risks. This research has important policy implications for other countries with similar socio-economic features.

RESUMO

This study was aimed at examining the contribution of forest products to rural livelihoods and the socio-economic factors that influence household forest dependence in the Luki Biosphere Reserve. A structured questionnaire poll of 193 households randomly chosen from two enclaves in the Luki Biosphere Reserve, and focus group discussions were used to gather the data. For data analysis, a binary logistic regression model was used. The study revealed a substantial contribution of forest products to household livelihood based on household wealth strata and the gender of the household head. The contribution of forest income has been found to be higher for poor households than to other wealth categories, although their mean income from forest was low. However, the present research further revealed that household forest dependence was significantly determined by socioeconomic factors such as length of residency, age, sex, education, employment and household size. Compared to their elderly counterparts, the youth were probably more dependent on forest products. Therefore, there should be increased capacity-building efforts among the young people to enable them enlighten the local communities about the need for sustainable forest management. Meanwhile, highly educated people were observed to be less dependent on forests. The findings of this research provides empirical evidence from the Mayombe tropical forest, thus contributing to the growth of knowledge on the impact of socioeconomic factors on the household dependence on forest resources, especially in the tropical forest of the Democratic Republic of Congo where the complexity of the relationship between local communities and their environment is still being studied.

RESUMO

Global climate change has seriously threatened agriculture and connected sectors, especially in developing countries like India. The Brahmaputra Valley in Assam, Northeast India, is vulnerable to climate change due to its agrarian economy, fragile geo-ecological setting, recurrent floods and droughts, and poor socioeconomic conditions of the farmers. The climate-induced hindrances faced by the rice farming community of this region and the local adaptation practices they employ have not been adequately studied. Therefore, we carried out a survey among 635 rice farmers across four agro-climatic zones of Assam, namely the Upper Brahmaputra Valley Zone, North Bank Plain Zone, Central Brahmaputra Valley Zone, and Lower Brahmaputra Valley Zone, to understand how they perceive and respond to climatic changes. The survey revealed that all the respondents have perceived an increase in ambient temperature, and 65% of the respondents have perceived a slight change in rainfall characteristics over the years. Most farmers reported adjusting the existing farming practices and livelihood choices to adapt to the changing climate. Farming adjustments were made mainly in terms of field preparation and management of water, rice variety, nutrients, and pests. Environmental variables like rainfall, flood, drought, and pest level, and socioeconomic variables like family size, education, farming experience, training, digital media exposure, and land area were found to influence farmers' adaptation choices. The findings imply that policies to strengthen flood, drought, pest management, education, land-use planning, agricultural training, and digital media applications in agriculture are needed for effective climate change adaptation in this region.

RESUMO

This study documents the socio-economic baselines in selected oil-impacted communities prior to the commencement of the Ogoni clean-up and restoration project. Adopting mixed approach consisting of semi-structured interviews, focus group discussions (FGDs), key informant interviews (KIIs), and household surveys, we surveyed the pre-remediation socio-economic conditions in the Ogoniland communities between July 2018 and March 2019. Results indicated that almost all respondents (99.6%) agreed that the smell of petroleum products or crude oil was evident in the air they breathed even as there were visible black particles (soot) in the respondents' nostrils, on their clothes, and in water. The respondents described the ambient air as smoky and choked with an offensive smell. The household waters were smelly, brownish, or oily, and most respondents (76%) cannot afford to treat their water. Forty-two percent of the respondents who relied on fishing and farming for a living sought for alternative means of subsistence and acknowledged that oil pollution caused stunted growth and low crop yield. The majority of respondents (91%) reported falling fish catches, while the fish caught smell and taste of oil, lowering their market value and posing a potential health risk to consumers. It is evident that oil pollution has impacted the socio-ecological values and sustainable livelihood in Ogoniland. This study provides baseline data for monitoring post-remediation socio-economic improvements in Ogoniland. It also highlights areas of urgent intervention to improve livelihood, and access to basic amenities (e.g., potable drinking water), waste management infrastructure, and statutory policy changes for sustainable development in Ogoniland.

RESUMO

Oil production in the Niger Delta first attained global prominence after the 1995 hangings of Ken Saro-Wiwa and eight other Ogonis. In the face of horrible publicity and credible allegations that international oil companies were complicit in systematic human rights violations against local host communities, corporate social responsibility (CSR) was embraced. CSR in the Nigerian oil industry has evolved from non-existent to limited community development programs to today's Global Memorandum of Understanding model. Yet, concomitant with CSR's growth has been a devastating increase in artisanal oil refining or "bunkering." In this article, we do not focus on industrial scale bunkering, which clearly requires high-level political support. Instead, we focus on the growth of small-scale artisanal refining in the rural Niger Delta. We situate this sector's growth in failed government and CSR policies, highlight its devastating environmental impacts, and advocate a shift away from flawed and limited CSR to legal and regulated modular refineries that, with fewer negative developmental and environmental externalities, could serve as a vital source of job creation and wealth generation.

RESUMO

Ecosystem services (ES) embrace contributions of nature to human livelihood and well-being. Reef environments provide a range of ES with direct and indirect contributions to people. However, the health of reef environments is declining globally due to local and large-scale threats, affecting ES delivery in different ways. Mapping scientific knowledge and identifying research gaps on reefs' ES is critical to guide their management and conservation. We conducted a systematic assessment of peer-reviewed articles published between 2007 and 2022 to build an overview of ES research on reef environments. We analyzed the geographical distribution, reef types, approaches used to assess ES, and the potential drivers of change in ES delivery reported across these studies. Based on 115 articles, our results revealed that coral and oyster reefs are the most studied reef ecosystems. Cultural ES (e.g., subcategories recreation and tourism) was the most studied ES in high-income countries, while regulating and maintenance ES (e.g., subcategory life cycle maintenance) prevailed in low and middle-income countries. Research efforts on reef ES are biased toward the Global North, mainly North America and Oceania. Studies predominantly used observational approaches to assess ES, with a marked increase in the number of studies using statistical modeling during 2021 and 2022. The scale of studies was mostly local and regional, and the studies addressed mainly one or two subcategories of reefs' ES. Overexploitation, reef degradation, and pollution were the most commonly cited drivers affecting the delivery of provisioning, regulating and maintenance, and cultural ES. With increasing threats to reef environments, the growing demand for assessing the contributions to humans provided by reefs will benefit the projections on how these ES will be impacted by anthropogenic pressures. The incorporation of multiple and synergistic ecosystem mechanisms is paramount to providing a comprehensive ES assessment, and improving the understanding of functions, services, and benefits.

RESUMO

Fishing and sand mining in Cambodia may not appear to have much in common. However, digging deeper reveals important parallels. Both fishing and sand mining support livelihoods and are connected to a limited natural resource. Meanwhile, they are both typified by precarious livelihoods, on the one hand, and overexploitation, on the other. In bringing these two topics together, the paper combines empirical qualitative research from two separate studies conducted by the co-authors in Cambodia, one in coastal fishing villages and another in the sand mining industry along the Mekong River. We argue that the interplay between fishing and sand mining has paradoxical impacts on livelihoods, supporting one group while undermining another. Using a precarity analysis lens, we show how an unconventional, and largely invisible frontier of natural resource exploitation-sand mining-is intertwined with fisheries, and expands our understanding of the relationship between precarious labour, environmental change, and livelihoods.

RESUMO

The northeast of Madagascar is as diverse as it is threatened. The area bordering the Analanjirofo and SAVA regions contains six protected areas and at least 22 lemur species. Many applied research and conservation programs have been established in the region with the aim of ensuring both wildlife and people thrive in the long term. While most of the remaining humid evergreen forest of northeast Madagascar is formally protected, the local human population depends heavily on the land, and unsustainable natural resource use threatens this biodiversity hotspot. Drawing from our collective experiences managing conservation activities and research programs in northeast Madagascar, we discuss the major threats to the region and advocate for eight conservation activities that help reduce threats and protect the environment, providing specific examples from our own programs. These include (1) empowering local conservation actors, (2) ensuring effectively protected habitat, (3) expanding reforestation, (4) establishing and continuing long-term research and monitoring, (5) reducing food insecurity, (6) supporting environmental education, (7) promoting sustainable livelihoods, and (8) expanding community health initiatives. Lastly, we provide a list of actions that individuals can take to join us in supporting and promoting lemur conservation.

RESUMO

Agrobiodiversity is often touted as a crucial adaptation strategy to mitigate risks linked to climate change by increasing the response capability of a system to external shocks and, consequently, the smallholder's resilience. This scoping review, conducted following the PRISMA protocol, aims to elucidate how agrobiodiversity's effect on resilience has been conceptualized, analyzed, and reported in the literature and to identify knowledge gaps. We systematically examined 193 articles, with 63 selected for full review based on predefined criteria. Notably, only 16 studies featured actual measurements of the effect of agrobiodiversity on resilience. Our findings indicate that articles often operationalize these complex theoretical concepts using limited variables. Agrobiodiversity is typically measured by crop count, while resilience is assessed through economic, ecological, and/or social dimensions. We identified key attributes expected in resilient systems and found that agrobiodiversity's impact on resilience was positive in 10 cases, negative in 9, and contingent on production types and system shocks in others. This review emphasizes the context-dependent agrobiodiversity-resilience relationship and the need for tailored agricultural diversification strategies. We discuss how inconsistencies between theoretical concepts and practical measures may compromise study validity and comparability and how smallholder context can influence resilience conceptualization. Based on our findings, we propose guidelines for future research and emphasize the need for improved metrics, empirical evidence generation, and mixed-method approaches. Our findings prompt further exploration of key questions to advance our understanding of agrobiodiversity's role in fostering agricultural resilience.

RESUMO

Working equids provide a crucial contribution to the livelihoods and food security of communities in low- and middle-income countries (LMICs). Nevertheless, they are a neglected category within animal health policies and interventions of governmental and non-governmental institutions. This critical review aims to assess the socioeconomic impact of diseases of working equids in LMICs. By highlighting the implications of diseases on working equid welfare, human wellbeing and livelihoods, this review seeks to sensitise policymakers within governments and international organisations to develop policies and interventions aimed at protecting the health of working equids and, consequently, the health and livelihoods of their dependent communities. Twenty relevant publications were identified through the search of five databases (CAB Abstracts, Web of Science Core Collection, BIOSIS, EMBASE and Scopus), backward citation searching and screening of indexes of proceedings and Special Issues retrieved from the database search. The review findings show that diseases of working equids have detrimental socioeconomic effects. However, this subject is under-researched and restricted to few diseases and geographical settings. Considering the complexity of the issue, this review demonstrates that the 'One Health' approach represents an opportunity to clarify the link between equid health, human wellbeing and livelihoods, facilitating the translation of research into policy.
