Agricultural Demand

As the most important resource for life, water has been a central issue on the international agenda for several decades. Yet, the world’s supply of clean freshwater is steadily decreasing due to extensive agricultural demand for irrigated lands. Therefore, water resources should be used with greater efficiency, and the use of non-traditional water resources, such as Treated Wastewater (TW), should be increased. Reusing TW could be an alternative option to increase water resources. Thus, many countries have decided to turn wastewater into an irrigation resource to help meet urban demand and address water shortages. However, because of the nature of that water, there are potential problems associated with its use in irrigation. Some of the major concerns are health hazards, salinity build-up, and toxicity hazards. The objectives of this comprehensive literature review are to illuminate the importance of using TW in irrigation as an alternative freshwater source and to assess the effects of its use on soil fertility and other soil properties, plants, and public health. The literature review reveals that TW reuse has become part of the extension program for boosting water resource utilization. However, the uncontrolled application of such waters has many unfavorable effects on both soils and plants, especially in the long-term. To reduce these unfavorable effects when using TW in irrigation, proper guidelines for wastewater reuse and management should be followed to limit negative effects significantly.

Abstract In December 2021, the Malta X Conference “Frontiers of Science: Innovation, Research and Education in the Middle East—A Bridge to Peace” will mark the celebration of the tenth anniversary of the Malta Conferences. The first Malta Conference was held on the island of Malta in 2003 amidst the height of the Second Intifada. Since then, the Malta Conferences Foundation (MCF) has been a pioneer in using science diplomacy as a bridge to peace and sustainable development in the Middle East [1]. MCF uses science diplomacy to advance the following four UN Sustainable Development Goals: 1. Ensure inclusive and quality education for all (Goal 4) 2. Ensure access of Water and Sanitation for all (Goal 6) 3. Ensure access to affordable, reliable, sustainable, and modern Energy for all (Goal 7), and 4. Promote Peace and Justice, as well as inclusive societies (Goal 16). In 2016, MCF received the UN NOVUS Summit award for Goal 16: Peace and Justice [2]. The Summit was held in the UN General Assembly.

Bioenergy is expected to play a key role in achieving a future sustainable energy system. Sweet sorghum-based fuel ethanol, one of the most promising bioenergy sources in China, has been receiving considerable attention. However, the conflict between sweet sorghum development and traditional water use has not been fully considered. The article presents an integrated method for evaluating water stress from sweet sorghum-based fuel ethanol in China. The region for developing sweet sorghum was identified from the perspective of sustainable development of water resources. First, the spatial distribution of the water demand of sweet sorghum-based fuel ethanol was generated with a Decision Support System for Agrotechnology Transfer (DSSAT) model coupled with Geo-Information System (GIS). Subsequently, the surplus of water resources at the provincial scale and precipitation at the pixel scale were considered during the growth period of sweet sorghum, and the potential conflicts between the supply and demand of water resources were analyzed at regional scale monthly. Finally, the development level of sweet sorghum-based fuel ethanol was determined. The results showed that if the pressure of water consumption of sweet sorghum on regional water resources was taken into account, about 23% of the original marginal land was not suitable for development of sweet sorghum-based fuel ethanol, mainly distributed in Beijing, Hebei, Ningxia, Shandong, Shanxi, Shaanxi, and Tianjin. In future energy planning, the water demand of energy plants must be fully considered to ensure its sustainable development.

Resources Development

Despite the ‘immense’ water resources available, Nepal has not been able to transform this abundance of water resources into desired economic growth and societal welfare. This paper attempts to analyze the reasons for such incessant challenges that loom over water resources development in Nepal. This paper finds that it is not the resource that limits the development of water resources, but the approaches and wishes that are framed on the foundation of persistent myths. Analyzing those myths, this paper highlights the realities in water resources management of Nepal, and suggests that without dismantling the existing myths, the sustainable development of water resources seems limited.HYDRO Nepal JournalJournal of Water, Energy and Environment Issue: 23Year: 2018

Wastewater Reclamation And Reuse

An integrated technical-economic model is used to address water management issues in the French island of Noirmoutier. The model simulates potable water production and supply, potable and non potable water demand and consumption, wastewater collection, treatment and disposal, water storage, transportation and reuse. A variety of water management scenarios is assessed through technical, economic and environmental evaluation. The scenarios include wastewater reclamation and reuse for agricultural and landscape irrigation as well as domestic non potable application, desalination of seawater and brackish groundwater for potable water supply. The study shows that, in Noirmoutier, wastewater reclamation and reuse for crop irrigation is the most cost-effective solution to the lack of water resources and the protection of sensitive environment. Some water management projects which are regarded as having less economic benefit in the short-term may become competitive in the future, as a result of tightened environmental policy, changed public attitudes and advanced water treatment technologies. The model provides an appropriate tool for water resources planning and management.
