Explore the adoption of rainwater management practices in the Blue Nile region through an analysis of the IFPRI Farm Survey on climate change. This study aims to improve rural livelihood resilience in the Ethiopian highlands by implementing landscape-based rainwater management strategies. The internship timeline includes processing and aggregating the survey data, identifying key variables related to water and soil conservation practices, and running initial adoption models. With a focus on socio-economic constraints, the project aims to create feasibility maps for rainwater management strategies, enhance adoption rules based on census data, and integrate socio-economic factors into feasibility assessments. The research delves into household characteristics, water sources, access to resources, crop and livestock practices, and perceptions of climate change. By incorporating mapping techniques and adoption models, the study seeks to address water scarcity concerns, reverse land degradation, and promote sustainable water management practices in the Nile Basin region.

Nile Basin Development Challenge Objective: to improve the resilience of rural livelihoods in the Ethiopian highlands through a landscape approach to rainwater management. • Water scarcity and land degradation – concerns livelihoods of millions households in Sub-Saharan Africa • Water for agriculture – crop production to feed population and Animal 70 to 90% of the all water used in the region. • Growing populations • Need - to reverse land degradation - to improve water productivity. • Landscape (watershed) approach to rainwater management To better target or ‘match’ promising technologies (or whole strategies) with particular environments.
Nile Basin Development Challenge N3 : on Targeting and scaling out Objective : creating feasibility maps for rainwater management strategies that include socio-economic constraints. One approach : Mapping Willingness of Adoption Procedure : Define adoption rules Based on census data (=data for the whole basin), simulate “virtual farmers” Run adoption rules on the simulated farmer

Objective of the internship • Aggregate the IFPRI “Climate Change” survey (phase 1) to farm level • Describe the dataset in terms of Water Related and Soil Conservation Practices • Compute Variables • Run first Adoption Models
IFPRIFarmSurvey on Climate Change (2005) • General features: Geo-referenced (GPS coordinates) 1,000 households (6,168 individuals) 3 Regions: Fogera, Jeldu and Dapo areas.

Perception of Climate Change (over last 20 yrs) • Variation of Rainfall Declined according to 61.53% Hh • Variation of Temperature # of Hot Days, 67.72% Hh • Perceived Cause of rainfall variation Poor vegetation cover (78.98% ) • Variation of vegetation cover 50% Hh unchanged, for 35% decreasing. • Major constraints in changing your farming ways
Perception of Climate Change (cont’d) • Adjustments made to LT shifts - in temperature - in rainfalls
Willingness to Adopt Model Specification • The framework can be estimated with a multivariate PROBIT estimation. Qualitative depend variable Probit: linear probability model y= α+ βn,ixn,i+ βn+1,ixn+1,i+εi y= Pr(PumpT) • Coefficient Estimators are not BLUE • R² is not a good measure of equation performance. Pseudo-r² (goodness-of fit, maximum loglikelihood)
Results: First Adoption Models 1. Adoption of Pump as a Water Management Strategy technology
3. Adoption of SC Techniques (Soil bunds, Stone bunds, Grass Stripes and Plouhging contour)
Results • PUMPS More productive farmers, closer to market, hiring labour, owning oxen and being informed. • TREE PLANTING Plot near homestead, middle size farmers • SC TECHNIQUES Poorer farmers, further from market & more likely to received Aid
