Biodiversity Under Climate Stress: Pathways to Resilient and Sustainable Food Systems

Incorporating plant biodiversity in Climate-Smart Agriculture (CSA) is crucial in planning for climate change and food security. Plant and animal species are basic elements of any ecosystem that sustain agricultural production through services such as nutrient cycling, pest control, and soil health. Some of the practices include agroforestry, intercropping, and conservation tillage, which can help CSA impact climate change challenges favorably without undermining ecological stability. However, the actual achievement of such strategies to promote the conservation of biodiversity is not without challenges such as financial constraints, lack of technology, and poor policy coherence. Monocultures and high-input farming systems have in the past emphasized production to the detriment of environmental considerations and have thus caused habitat destruction and species simplification. This chapter calls for policies, incentives, and community support in enhancing the practice of biodiversity in agriculture. Measures such as agri-environmental schemes, biodiversity credit trading, and payments for ecosystem services are presented as powerful means of encouraging farmers. Furthermore, the use of traditional knowledge in the formulation of biodiversity management strategies and participation ensures that the strategies developed fit for culture and relevant to the local situation. There is now a great appreciation of technology in the assessment of biodiversity in various ecosystems as well as in the formulation of adaptive management measures through the use of remote sensing and GIS. The research also underlines the importance of international cooperation and policy harmonization for the further development of the biodiversity-related CSA practices. The convention on biological diversity (CBD) and other national and global policies must therefore harmonize to ensure that there are proper policies that can foster conservation of biodiversity. This chapter has discussed how economic, ecological, and social advantages make the incorporation of biological diversification into CSA a sound method for attaining sustainable agriculture. Technically, these systems cut on production costs and increase output, especially in the constraining conditions of resource based farming systems. Conservation wise, they help protect species, habitats, and ecosystem services that are vital for the overall sustainability of the environment.
