Assessment of Implementation of Rainwater Harvesting Structures in Drylands Areas and Their Challenges West Harareghe Zone, Chiro, Ethiopia

The main problem of this 21<sup>1st</sup> century is lack of water and contamination of water. Even if Ethiopia has water tower country in the eastern Africa; she has known as scarcity of water both in quality and quantity. This study will be entitled with: assessment of implementation of rainwater harvesting structures in drylands areas and their challenges west Harareghe zone, Chiro Ethiopia. The objectives include: two phases: first phases include the following objectives-to identify the causes and factors that are adversely affects rainwater harvesting; to evaluate the challenges prevent rainwater harvesting and its utilization; to recognize the success and an exemplary model of rainwater harvesting areas; to investigate the consequence impacts of the failure of rainwater harvesting and to identify the socio-economic and environmental effects of rainwater harvesting. second phases include: implementation of model RWH structures for crop production on farm land, for forest tree production on forest land and for livestock consumption and fodder production on pasture land, for wild animals consumption and rehabilitation of their habitat through keeping of livestock and wild animals ecosystem balance; to be monitoring and evaluating the project and then transferring to other areas having similar agro-climatic conditions, topography and soil types. Of all identification of soil textures similarity to before losses of transfer of economy to other areas. Random sampling techniques will be considered by taking 10% of the PA population for interview through their stratification of random sampling techniques based on the criteria stated under the methodology.
