How to do a Cost-‐Benefit Analysis in ELD: a case study from the Ethiopian Highlands Hans Hurni University of Bern ELD Ethiopia Project Scope: Soil degradaBon and sustainable land management in rain-‐fed agriculture LocaBon: Ethiopian Highlands SpaBal scale: MulB-‐scale from local to naBonal Strategic focus: Provide a spaBally explicit model for cost-‐benefit analysis (CBA) of sustainable land management (SLM). Define further inputs for modelling the total economic value (TEV) of the Ethiopian Highlands. Inform decision-‐makers about best opBons for sustainable water and land management in Ethiopia. The Ethiopian Highlands 3 C. Hormann 2006 H. Hurni 1998 4 The ELD Ethiopia Team in Addis Abeba on 13-‐15 January 2014 Defini9on of Total Economic Value (TEV): “The full economic value allocated by society as a whole. This includes use value (direct and indirect, opBon value) and non-‐use value.” ELD IniBaBve 2013 Case study Ethiopian Highlands: -‐ direct use value through agricultural (crop and livestock) producBon -‐ indirect use value through water (and sediment) delivery for lowland irrigaBon -‐ opBon value for ecotourism and biodiversity (e.g. wildlife) conservaBon -‐ non-‐use value through water (and sediment) delivery for lowland irrigaBon Cost-‐benefit analysis: “A comparison of all of the costs and benefits associated with taking acBon, compared to ‘business-‐as-‐usual’ (changing nothing). ” ELD IniBaBve 2013 ELD Ethiopia Project 2014 Spa9ally explicit case study of the direct agricultural use value of land in the Ethiopian Highlands: -‐ Costs and benefits of past and actual (SWC) acBon -‐ Costs and benefits of opBmum (SLM) acBon -‐ Costs and benefits of ‘business-‐as-‐usual’ (inacBon) 8 H. Hurni, 1981 Recalling the 6+1 steps to es9mate the economic benefits and costs of ac9on 1. Incep9on: IdenBficaBon of the scope, locaBon, spaBal scale, and strategic focus of the study 2. Geographical characteris9cs: Assessment of quanBty, spaBal distribuBon, and ecological characterisBcs 3. Types of ecosystem services: Analysis of ecosystem services stocks and flows 4. Role of ecosystem services in community livelihoods and economic valua9on: Role of the assessed ecosystem services in the livelihoods of the communiBes; role of overall economic development 5. Land degrada9on paRerns and pressure: IdenBficaBon of land degradaBon paaerns, drivers and pressure on the sustainable management of land resources 6.
