Abstract

Rainwater harvesting (RWH) is the way to reduce the effects of mid-season dry spells and drought, which often reduce crop yields. Geographic information system (GIS) with multi-criteria decision making (MCDA) is a powerful tool to identify and solve spatial problems like the identification of the suitable site of RWH. Sentinel image, soil, metrological row data, geological data, and digital elevation model (DEM) data were the source of a dataset to undertake the preprocessing, manipulation, and analysis the suitable site identification by using GIS and remote sensing spatial analysis. More than seven parameters where identified based on an extensive literature review which is land use/land-cover, soil textural, rainfall, lineament, slope, runoff density and curve number, distance from settlement and road. The multi-criteria decision-making method was used for weight value estimation of each criterion and finally, the rainwater harvesting suitability map was generated. The potentially suitable site was grouped into four levels of suitability, which accounts in hectare 3,620, 16,0618, 69,867, and 14,010 ha of highly suitable, moderately suitable, less suitable, and restricted respectively from the total area coverage of 248,115 ha respectively.

Abstract

Climate change is one of the life-threatening challenges that face the ecosphere in recent decades. Climate change exacerbates the rate and magnitude of several ongoing land degradation processes. The impact is particularly high in unindustrialized states like Ethiopia. In recognition of the impact adaptation become the policy options to minimize the adverse effects of climate change. The main objective of this research paper is to analyze the determinants of farmers’ choice of land management approaches to climate change in drought prone areas of Amhara region: the case of Lay Gayint woreda, Northwestern Ethiopia. The study employed a multistage stratified sampling procedure (purposive and simple random). Data were obtained from 232 sample households. Primary data were collected from households via questionnaires, interview and focus group discussion. The households’ land management strategies to climate change were summarized by using percentage. Binary logistic regression model was also applied to analyze the factors that influence farmers’ choice of land management strategies. The farming households of the study area have attempted to give response to the impacts of climate change; but their capacity to adapt is challenged by a number of factors. Model results indicate that, Agro ecological setting and non-farm activities are found to be the most statistically significant determinants in the adoption of land management strategies. Solving financial problems, improving extension service, providing timely information and establishing early warning system, livelihood diversification and integrated watershed management practice would enable to increase the adaptive capacity of farmers
