Development of an adaptation model by applying non-linear programming to compute adaptation deficiency in climatic hotspots

For the policy makers, risk-based planning to minimize future climatic risk needs decision on investment priority. This is particularly important where there are resource constraints, and in cases where the decisions depend on socio-political reality of the region. For the policy makers, it is also...

This is particularly important where there are resource constraints, and in cases where the decisions depend on socio-political reality of the region. For the policy makers, it is also extremely important to know how a system will behave if investment is made on any specific adaptation in any specific location to minimize climatic risk in the region. To answer these questions, an Adaptation Model is developed in this study to compute adaptation deficiency for a location that will minimize climatic risk in that location. In this methodology, a system approach is followed by applying non-linear programming. The non-linear programming system is formulated by defining future climatic risk as the objective function where the risk is a non-linear function of hazard, exposure, vulnerability, where vulnerability is a linear combination of sensitivity and adaptive capacity.

The output from the model can be used by the policy makers to decide on the most appropriate investment options for risk-based planning that will minimize future risks in the identified hotspots. The model shows the risk limit below which risk cannot be reduced. Any investment attempt on adaptation to reduce the risk beyond this limit will disrupt the system equilibrium and will make this investment a surplus.Marin AkterAnisul HaqueDewan Sadia KarimMunsur RahmanMashfiqus SalehinRubaiya KabirMohammad Abdul AlimMohammad Asif ul HaqElsevierarticleRisk hotspotNonlinear programmingSystem approachRisk minimizationAdaptation deficiencyRisk-based planningEnvironmental sciencesGE1-350Social sciences (General)H1-99ENProgress in Disaster Science, Vol 12, Iss , Pp 100201- (2021)
