Factors Affecting Rainwater Harvesting Practices: In Case of Assosa Town, Upper Blue Nile Basin, Northwestern Ethiopia

In many parts of the world, conventional water supplies do not exist, are unreliable or prohibitively expensive. Many actual or potential water shortages can be alleviated if the practice of rainwater harvesting becomes widespread. A study was conducted to evaluate the factors affecting rainwater harvesting practices in Assosa city. The reason for starting the research is that the municipality of Assosa suffers from a severe water shortage, especially at the end of the dry season. The study involved 99 randomly selected respondents and purposively selected respondents using a semi-structured questionnaire. Data were collected using a combination of data collection methods including survey interviews, key informant interviews, and direct observation. The data was analyzed using descriptive statistics such as frequency tables to draw conclusions and recommendations. The results showed that lack of funding played a key role in the adoption of rainwater harvesting and, furthermore, lack of information and poor technology contributed to the failure to adopt rainwater harvesting for domestic use. It was determined that roofing materials were not a problem in the area, but storage areas and gutters hindered rainwater collection. We therefore concluded that the implementation of rainwater harvesting systems in Assosa town was hampered by the lack of resources required for the installation of rainwater harvesting systems. In addition, inadequate accesses to information, particularly for women, and lack of knowledge about the maintenance of rainwater harvesting technologies have contributed to the lack of widespread adoption of rainwater harvesting. We recommend making a conscious effort to subsidize rainwater harvesting in this area. The study also recommends strengthening municipal capacities in the area of rainwater harvesting technology, which is expected to be important for improving rainwater harvesting technology.
