Sustainable water resources management under water-scarce and limited-data conditions

Urbanization and population growth increase the demand for freshwater abstraction, food production, rising thus the agricultural, economic, and productivity expectations. The need for improved water services, sustainable and resilient management under changing climate, are major drivers to set forth the redesigning of water planning. Water scarcity combined with the limited expansion of new infrastructure create competition among water uses and further stress the satisfactory coverage of the increasing needs. Integrated modeling is a way to simulate and address the above challenges, however, poor monitoring, incomplete databases, and complexity make its applications difficult. Questions such as what data to use, how to best exploit the (limited) available databases, what parameters to calculate, and how to satisfy both economic and environmental objectives, occur. This study presents a novel Decision Support System (DSS), combining hydrology, economics, engineering, and social aspects, aimed to participatory management, using simple concepts, and discussing assumptions for working with limited data, and useful parameters to estimate. Water availability and demand, water quality, profits, costs, and management scenario analysis, including nature-based solutions, are explored under climate change scenarios, and alternative policies are evaluated. The combination of the above and the useful modeling insights, under water- and data-scarcity conditions are novel elements, while the aim is to encourage integrated and sustainable water resources management through understandable and user-friendly DSSs.

Studi Eksplorasi Tentang Harapan Masyarakat terhadap Keberadaan Aset Wisata Embung Tambakboyo Kabupaten Sleman Daerah Istimewa Yogyakarta

Water Resources must be managed in a comprehensive, integrated and environmentally sound in order to realize the benefit of sustainable water resources for the prosperity of society. For the participation in exploring the public’s expectations of the existence of an asset for tourism Embung Tambakboyo together to built awareness and understanding in the management of water resources in order to have available economic value for sales to tourists. Three things in this effort are I. The changing social function of the water from the objects to objects that have economic value, 2. The changing nature of the waters Public Property inti an economic commodity that can be controlled by private owners, 3. Shifting role of government from provider to facilitator. From the analysis can be concluded that based on the variables of economic, social and community participation of the three community groups (MU, PKL, KET). An increase in the economy is the main hope of street vendors and community groups have the highest expectations compared to the MU and KET. Be comprehensive to date has been the existence of Embung Tambakboyo has many positive benefits for local peoples, social and environmental sector economic and Embung Tambakboyo worthy of man-made attractions.

Review: Sustainable Water Resources Engineering and Management; Nigerian Perspective

Water resources sustainability is essential to life because all living things and some non-living things need it to complete their processes. The water usage is rising, hence pressure on the availability, and some instances rose to crisis level. These pressures were due to population growth, increases in irrigated land, deforestation, soil and land degradation, and wastages. Engineering is one of the majors’ components in tackling water resources sustainability. Therefore, this paper reviews the general concepts of sustainable water resources from an engineering and management perspective. The method adopted to realize the aim of the research was a thorough literature review. Engineering has three sub-components, these are Ecological, Economic, and social sustainability. Failure in one of these sub-components is a failure of the component. The literature revealed that Water resources sustainability is a multifaceted discipline therefore, engineering discipline alone would not solve it. However, this paper proffered some recommendations and the way forward. These recommendations are the steps required at the watersheds level, the engineering strategies aspects, and the management strategy. It concluded that a holistic approach where all shareholders will be involved is an ideal approach.

Machine Learning with Metaheuristic Algorithms for Sustainable Water Resources Management

Management of available water resources needs good planning and to do this, prognostication of hydrological parameters (parameters of the hydrological cycle such as rainfall, runoff, solar radiation, groundwater, evaporation/evapotranspiration) [...]
