The studied groundwater is dominated by HCO3, Ca, and Mg ions. According to the World Health Organization (WHO) and Algerian standards, all groundwater samples are considered safe and fit for drinking as they fall within the permissible limits. In addition, the Schoeller diagram confirms the best quality water of the Hauterivian groundwater. Gibbs diagram show that the predominant samples fall in the rock-water interaction field, suggesting that water-rock interactions are the major mechanism controlling groundwater chemistry. Assessment of groundwater samples using various water quality indices such as sodium absorption ratio (SAR), soluble sodium percentage (SSP), residual sodium carbonate (RSC), magnesium hazard (MH) and Kelly ratio (KR) showed that the groundwater in the area has an excellent quality for irrigation purpose. According to Wilcox’s diagram, all groundwater samples fall in the C2S1 category, reflecting that they are suitable for irrigation.","PeriodicalId":39224,"journal":{"name":"Journal of Water and Land Development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68949870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To encourage government, business, community and other parties to continue investing in flood risk management projects, it is necessary to give understanding that the projects can also provide economic benefits through systematic predictions and assessments of costs, benefits and social values, especially on flood-affected communities. This study aims: (1) to develop knowledge and understanding on small-scale flood risk management project in Malang City, Indonesia, and; (2) to assess the economic efficiency of the project investment considering all benefits, both monetary and non-monetary. The research method is a mixed method combining quantitative questionnaires (N = 53 from 162 families) with qualitative in-depth interviews (N = 10) and field observations. The runoff discharge and the inundation depth were calculated using hydrology and hydraulic analysis, while the economic efficiency was analysed using cost benefit analysis (CBA). The results show that the community-based flood risk management system can reduce the flood risk up to 30% compared to before the implementation of that system. This system also provides direct financial benefits through the use of drainage channels for fish and vegetables farming. It causes the increase of the net social benefit about 70–90% and the net present value (NPV) greater than zero (NPV > 0). Therefore, the project investment is recommended to be proceeded.","PeriodicalId":39224,"journal":{"name":"Journal of Water and Land Development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68950055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Southeast Asian countries are facing severe water scarcity challenge due to their location in the tropics. In 2018, the Sumba Island experienced the highest temperature of 36°C and lesser rainfall of 911.1 mm per year and it was classified as a long dry island prone to drought due to dry winds from Australian desserts. This paper focuses on the perceived effect of water scarcity on livelihoods in the Mandahu Village, Indonesia, due to climate change. Sampling and survey covered rural households and the findings showed that the average household of 4 to 8 people consumed around 250 dm of water per day. The community relied on two main sources of clean water from two main springs. However, the prolonged dry season from May until December every year results in major challenges to access water and eventually affect the agricultural productivity. Hence, the feasibility of the fog collection technology has been investigated from technological, economic and social points of view as a reliable and cost-effective source of water. The outcome of this work will produce a feasibility statement for fog-to-water as an alternative solution counteracting water scarcity in the Sumba Island, a solution which can be replicated in other climate change stricken hot spots in Southeast Asia.","PeriodicalId":39224,"journal":{"name":"Journal of Water and Land Development","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68950177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
