Mathematical Modeling Of Drought Resilience In Agriculture, Ram Ranjan
Mathematical Modeling Of Drought Resilience In Agriculture, Ram Ranjan
Ram Ranjan
Ensuring drought resilience for farmers is an important policy concern. Yet, a quantitative treatment of the concept of drought resilience has been lacking in the literature. This paper designs a mathematical model of drought resilience to assess farmers’ survival strategies when faced with the prospect of repeated droughts. A key distinction is being made here between consecutive droughts and one-off droughts, as it is the former which is of most concern to farmers as well as policy makers. The mathematical model is generalized to incorporate the possibility of more than one set of a certain number of consecutive droughts occurring …
Natural Resource Sustainability Versus Livelihood Resilience: A Model Of Groundwater Exploitation Strategies In Developing Regions, Ram Ranjan
Ram Ranjan
This paper designs a stylized model representing farming in water scarce regions of south India to address the problem of managing depleting groundwater assets facing the threat of irreversible loss. Circumstances under which it may be optimal to forgo sustainable water use are evaluated in the context of farmers’ wealth and land endowments, crop choices and risk of groundwater loss. Several policy and management implications are derived. Additionally, it is argued here that attaining livelihood resilience will entail a transformation process involving tradeoffs between different capital assets where it may be optimal for a farmer to forego the objective of …
