Abstract In response to water scarcity in Ajloun governorate, Jordan, the effectiveness of implementing rooftop rainwater harvesting (RRWH) was investigated. In addition, a structured questionnaire was prepared and distributed to randomly selected residents to assess the status of the current RRWH practices in the governorate and the people's perceptions of this practice. It was found that between 0.39 million cubic meters (MCM) in a dry year (2017) and 0.96 MCM in a wet year (2018) can be harvested, which is equivalent to 7.6% and 16.8% of the domestic water supply for these years, respectively. The analysis of a total of 360 questionnaires revealed that only 14.2% of the households in Ajloun governorate own a RRWH system. However, the majority, 80.6%, of those who do not own a RRWH system showed interest in installing one. An overwhelming majority of the sample, 96.7%, believes that the government should provide incentives to subsidize the construction of RRWH systems, which is attributed to the high initial cost of these systems. The technical and social feasibilities of RRWH, in addition to the high cost of the alternatives, justifies providing incentives, such as cost sharing for the consumers in Ajloun to implement RRWH systems.

Rooftop Rainwater Harvesting

In highly water-poor areas, rooftop rainwater harvesting (RRWH) can be used for a self-sustaining and self-reliant domestic water supply. The designing of an optimal RRWH storage tank is a key parameter to implement a reliable RRWH system. In this study, the optimal size of RRWH storage tanks in the different West Bank governorates was estimated based on monthly (all governorates) and daily (i.e., Nablus) inflow (RRWH) and outflow (domestic water demand, DWD) data. In the estimation of RRWH, five rooftop areas varying between 100 m2 and 300 m2 were selected. Moreover, the reliability of the adopting RRWH system in the different West Bank governorates was tested. Two-time series scenarios were assumed: Scenario 1, S1 (12 months, annual) and scenario 2, S2 (8 months, rainy). As a result, reliable curves for preliminary estimation of optimal RRWH storage tanks for the different West Bank governorates were obtained. Results show that the required storage tank for S1 (annual) is more than that of the S2 (rainy) one. The required storage tank to fulfill DWD is based on the average rooftop area of 150 m2, the average family members of 4.8, and the average DWD of 90 L per capita per day (L/c/d) varies between (75 m3 to 136 m3) and (24 m3 to 84 m3) for S2 for the different West Bank governorates. Further, it is found that the optimal RRWH tank size for the 150 m2 rooftop ranges between 20 m3 (in Jericho) to 75 m3 (in Salfit and Nablus) and between 20 m3 (in Jericho) to 51 m3 (in Jerusalem) for S1 and S2 scenarios, respectively. Finally, results show that the implementation of an RRWH system for a rooftop area of 150 m2 and family members of 4.8 is reliable for all of the West Bank governorates except Jericho. Whereas, the reliability doesn’t exceed 19% for the two scenarios. However, the reduction of DWDv is highly affecting the reliability of adopting RRWH systems in Jericho (the least rainfall governorate). For instance, a family DWDv of 3.2 m3/month (25% of the average family DWDv in the West Bank) will increase the reliability at a rooftop area of 150 m2 to 51% and 76% for S1 and S2, respectively.

Globally food shortage is still a problem for instance Africa, the most of popular region in the world still has the highest of under nourished. The probable answer to what are the factors influencing food shortage In Tanzania are not well known and documented. This study sought to assess the factors influencing the food shortage in Mtwara Mikindani Municipality by identifying factors influencing food shortage, determining the status of food availability and accessibility and finding out the possible measures to be taken in order to overcome the problem of food. Structured questionnaire, observation and Oral interview had been useful for collecting primary information in which the best recorded interviewees were analyzed supplemented by documentaries. Generally, this study concludes that food shortage in the study area is influencing by, climate change, bad tradition believe, poor government support, laziness culture, land degradation and infertility land. However, the government should not delay to implement its policies practically especially to the small producers so as to establish strong base on agriculture. Also, the government to employ as many as it can agricultural officers so as to allow farmers to get frequent visitors who will  advise them on how to produce efficiently their products by using irrigation methods and scientific methods like the use of improved seeds.

The present study was conducted to assess food security the status of dairy farmers in haor areas of Sunamganj district, Bangladesh. Food security index and binary logistic regression analysis were applied to analyze the data and data were collected by face to face interview of randomly selected dairy farmers with a structured questionnaire. About 56 percent of the dairy farmers were food insecure as they took below 2122 kilo calorie per day per person and rest 44 percent was food secure. Occupation and number of milking cows were found significantly interrelated with food security of dairy farmers and education was also responsible for the food security of respondents. So it may be concluded that the government and other developmental organization should take essential steps which will ensure better dairy farming to improve the food security condition of dairy farmer and help to keep the dairy sector alive.

Domestic Water Supply

A safe rural domestic water supply project has been initiated based on different consumption uses. Long-term computation method and the water balance principle are used to analyze the yearly water demand. Water supply and demand balance is achieved through regulated planning of the rainwater collection surface area and water storage capacity. The best combination of collection area and storage capacity is then determined for various rainfall zones in order to satisfy safe domestic water needs. Ultimately, an optimum matching model is developed to utilize rainwater harvesting for providing safe domestic water in rural areas.

Domestic Water Supply

In this paper the value of an improved domestic water supply was investigated for economic development and gender relations in rural households in a drought-prone area. A comparative study executed with participatory rural appraisal (PRA) methods with groups of women from 11 micro-enterprises in ten villages and five control villages showed that,when an improved domestic water supply does not function, the entrepreneurs groups have a statistically higher loss of the economic use of water and time than the control groups. The extra income that women gain when the supply works and is used economically helps poor families to bridge the dry season. It could further be quantitatively proven that male–female gender relations were significantly better in the entrepreneurs group. This was not so for mother–daughter relationships, which gave new insights into the need to address gender equality issues with the women themselves and with SEWA, the supporting agency. These findings support the view that rural poverty and the status of women would receive a significant boost if policy makers focused on providing employment opportunities for women along with improved water supplies.
