Abstract

CONTEXT

Climate change is influencing the integrity of agroecosystems, with negative impacts on food security, by modifying the crop types used and by altering the plant physiological and biochemical processes that sustain ecosystem service provisioning. In this new environmental context, understanding the spatial patterns and dynamics of climate change agroecosystems face is important for effective conservation and management.

OBJECTIVE

This study evaluates agroecosystems vulnerability to climate change through exposure, sensitivity, and adaptive capacity.

METHODS

The Shannon Entropy Weight method was employed to estimate the relative weights for individual indicators across the categories of exposure, sensitivity, and adaptive capacity. Indicators of exposure included change in temperature, precipitation variability, and natural disasters. Sensitivity was measured using crop production, livestock density, and distance from deforestation. Adaptive capacity was assessed by evaluating sustainable livelihood assets. These components were integrated into a vulnerability index to inform targeted management approaches.

RESULTS AND CONCLUSION

Ethiopia was identified as the country with the highest overall vulnerability, closely followed by Niger and Nigeria. These countries exhibited the highest vulnerability scores in the study, with Ethiopia showing the most pronounced levels of vulnerability.

SIGNIFICANCE

Mapping vulnerability assessment informs sustainable agroecosystems in climate change adaptation.

期刊介绍： Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments. The scope includes the development and application of systems analysis methodologies in the following areas: Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making; The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment; Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems; Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
