Practical actions for applied systematic conservation planning.

Systematic conservation planning is intended to inform spatially explicit decision making. Doing so requires that it be integrated into complex regulatory and governance processes, and there are limited instances where this has been achieved effectively. South Africa is a global leader in the application of conservation plans, the outputs of which are widely used for spatial planning and decision making in many spheres of government. We aimed to determine how conservation planning in the country progressed from theory to implementation, and to identify practical actions that enabled this transition, by assessing temporal trends in the characteristics of conservation plans (1990-2017, n = 94). Since 2010 conservation planning has entered an operational period characterized by government leadership of plans, administrative rather than ecological planning domains, decreasing size of planning units, increasing emphasis on end-user products, and scheduled revision of plans. Key actions that enabled this progression include transitioning leadership of plans from scientists to practitioners, building capacity within implementing agencies, creating opportunities to integrate plans in legislative processes, establishing a strong community of practice, adopting implementation-focused methods, and balancing standardization with innovation. Learning from this model will allow other countries, particularly those with a similar megadiverse, developing context, to operationalize conservation planning into spatial planning and decision making.

Acciones Prácticas para la Aplicación de la Planeación Sistemática de la Conservación Resumen La intención de la planeación sistemática de la conservación es informar la toma de decisiones espacialmente explícitas. Para lograr esto se requiere la integración de la planeación sistemática dentro de los complejos procesos regulatorios y de gobernanza. Actualmente existen instancias limitadas en las que lo anterior se ha conseguido de manera efectiva. Sudáfrica es un líder mundial en la aplicación de planes de conservación, cuyos resultados se utilizan ampliamente para la planeación espacial y la toma de decisiones en muchas esferas del gobierno. Buscamos determinar cómo la planeación de la conservación ha progresado en este país desde la teoría hasta la implementación e identificar las acciones prácticas que permitieron esta transición, esto mediante la evaluación de tendencias temporales en las características de los planes de conservación (1990-2017, n = 94). Desde 2010 la planeación de la conservación ha entrado en un periodo operativo caracterizado por el liderazgo gubernamental de los planes, dominios administrativos en lugar de dominios ecológicos, la reducción del tamaño de las unidades de planeación, el incremento del énfasis sobre los productos de usuario final y una revisión programada de los planes. Las acciones clave que permitieron esta progresión incluyen la transición del liderazgo de los planes de los científicos hacia los practicantes, el desarrollo de capacidades dentro de las agencias implementadoras, la creación de oportunidades para integrar los planes dentro de los procesos legislativos, el establecimiento de una comunidad de práctica fuerte, la adopción de métodos enfocados en la implementación y el balance entre la estandarización y la innovación. El aprendizaje que proporciona este modelo permitirá que otros países, particularmente aquellos con un contexto similar en cuanto al desarrollo y a la megadviversidad, conduzcan la planeación de la conservación hacia la planeación y la toma de decisiones espacialmente explícitas.

A Socio-Ecological Approach for Identifying and Contextualising Spatial Ecosystem-Based Adaptation Priorities at the Sub-National Level.

Climate change adds an additional layer of complexity to existing sustainable development and biodiversity conservation challenges. The impacts of global climate change are felt locally, and thus local governance structures will increasingly be responsible for preparedness and local responses. Ecosystem-based adaptation (EbA) options are gaining prominence as relevant climate change solutions. Local government officials seldom have an appropriate understanding of the role of ecosystem functioning in sustainable development goals, or access to relevant climate information. Thus the use of ecosystems in helping people adapt to climate change is limited partially by the lack of information on where ecosystems have the highest potential to do so. To begin overcoming this barrier, Conservation South Africa in partnership with local government developed a socio-ecological approach for identifying spatial EbA priorities at the sub-national level. Using GIS-based multi-criteria analysis and vegetation distribution models, the authors have spatially integrated relevant ecological and social information at a scale appropriate to inform local level political, administrative, and operational decision makers. This is the first systematic approach of which we are aware that highlights spatial priority areas for EbA implementation. Nodes of socio-ecological vulnerability are identified, and the inclusion of areas that provide ecosystem services and ecological resilience to future climate change is innovative. The purpose of this paper is to present and demonstrate a methodology for combining complex information into user-friendly spatial products for local level decision making on EbA. The authors focus on illustrating the kinds of products that can be generated from combining information in the suggested ways, and do not discuss the nuance of climate models nor present specific technical details of the model outputs here. Two representative case studies from rural South Africa demonstrate the replicability of this approach in rural and peri-urban areas of other developing and least developed countries around the world.

Using changes in agricultural utility to quantify future climate-induced risk to conservation.

Much of the biodiversity-related climate change impacts research has focused on the direct effects to species and ecosystems. Far less attention has been paid to the potential ecological consequences of human efforts to address the effects of climate change, which may equal or exceed the direct effects of climate change on biodiversity. One of the most significant human responses is likely to be mediated through changes in the agricultural utility of land. As farmers adapt their practices to changing climates, they may increase pressure on some areas that are important to conserve (conservation lands) whereas lessening it on others. We quantified how the agricultural utility of South African conservation lands may be altered by climate change. We assumed that the probability of an area being farmed is linked to the economic benefits of doing so, using land productivity values to represent production benefit and topographic ruggedness as a proxy for costs associated with mechanical workability. We computed current and future values of maize and wheat production in key conservation lands using the DSSAT4.5 model and 36 crop-climate response scenarios. Most conservation lands had, and were predicted to continue to have, low agricultural utility because of their location in rugged terrain. However, several areas were predicted to maintain or gain high agricultural utility and may therefore be at risk of near-term or future conversion to cropland. Conversely, some areas were predicted to decrease in agricultural utility and may therefore prove easier to protect from conversion. Our study provides an approximate but readily transferable method for incorporating potential human responses to climate change into conservation planning.
