Governmental response to climate risk: Model-based assessment of livestock supplementation in drylands

摘要

Drylands cover 40% of the world's surface and provide the basis for the livelihoods of at least one billion people. Pastoralists in these regions face risk and uncertainty due to highly variable climatic conditions. Therefore, and due to global change, novel risk-coping management strategies have evolved in recent decades. For example, in many pastoral regions in drylands government supplementary feeding programs are commonly introduced as a strategy to address multiple societal challenges related to climate risks, such as poverty alleviation or the maintenance of resilient pastures, in a cost-efficient way. Therefore, it is crucial to assess government supplementation programs from a multi-criteria cost-benefit perspective.
