Groundwater management

This Technology Transfer Advances Sri Lanka's

• Nationally Determined Contribution and its adaptation targets to build climate resilience of sectors such as health, water management, urban infrastructure and settlement, which are vulnerable to the adverse impact of climate change.

Join our CTCN Consortium Partner, the Tropical Agricultural Research and Higher Education Centre (CATIE) for this introductory webinar on technologies for adapting to climate change in the water sector.

UNEP-DHI Partnership presents a series of 6 webinars that will give an introduction to the basic challenges and issues related to water quality.

According to this report, water security in Asia and the Pacific is under threat from many sources: population growth, urbanization, increasing water pollution, the over-extraction of groundwater, water-related disasters and climate change. Planning and management have proven insufficient to address the challenges of meeting society's diverse needs for water.

Research reports from the International Water Management Institute (IWMI).

This report outlines lessons learnt regarding the principal effects of climate change on 15 cities in low-income countries, and what makes them vulnerable to these effects. It notes that coastal cities are mostly located in tropical areas with hot and humid climates and low-lying land.

Water plays a pivotal role in economic activity and in human well-being. It is essential to food production and in domestic use (drinking, washing, and cooking). Yet the social relations which determine access to, and use of, water are poorly understood. Conflict over water may have far-reaching consequences on social change. This article introduces a framework for analysing different factors in accessing water and applies it to three related issues in Bangladesh. First, extraction of groundwater for irrigation has made many drinking-water hand pumps run dry.

According to this policy brief, climate and other drivers of change raise questions about the continued reliance on surface water resources, prompting countries to fundamentally rethink groundwater management strategies. This policy brief describes a case study from India, to show how the country is seizing the opportunity to use groundwater to face climate change. Similarly, another case study in Central Asia highlights how co-management of surface water and groundwater offers attractive and innovative solutions to complex, politicized water allocation problems.

Unique particles derived from acrylonitrile or other materials which are capable of selectively absorbing uranyl from groundwater surface water and wastewater.Applications:This technology can be used to improve the quality of a water supply by safely effectively and inexpensively removing uranyl ions from the water. The presence of uranium in groundwater is a growing problem in the United States and one without effective treatment to date. These particles can also be used in portable field systems for analysis of uranyl content on site.

Chemical contaminants such as nitrogenous wastes found in aquacultures or groundwater may contaminate nearby areas and drinking water supplies. Groundwater pollution may be caused by activities such as industrial waste disposal accidental spills fuel tank leakage or application of fertilizers herbicides or pesticides to crops. Natural causes such as arsenic also may result in groundwater contamination. Organisms are a major cause of water and aqueous environment contamination and are one of the world’s largest health concerns.
