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. 

Context

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

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.

Description

Climate change is expected to have a significant impact on water resources, necessitating the search for suitable adaptation options. However, understanding the impacts of climate change on water resources will not be possible without an in-depth knowledge of the hydrological cycle and hydrology. This website has a plethora of training material on hydrological concepts and processes; e.g., water cycle, hydrometry, topography, rating curves, data management, flow measurement and groundwater. Users interested in capacity building exercises should find this website useful.

The data is intended to assist in establishing the basis for highlighting the risks and vulnerabilities associated with groundwater use.

Groundwater is an important resource for livelihoods and food security of billions of people, especially in developing countries of Asia. Despite the significance of groundwater for sustainable development in Asia, it has not always been properly managed, resulting in depletion of the resource. Climate change impacts may add to existing pressure on groundwater resources by impeding recharge capacities in some areas and filling eventual gaps in surface water availability caused by increased variability of precipitation.

Enhancing water productivity is often recommended as a "soft option" in addressing the problem of increasing water scarcity. In this study, authors analysed the water productivity and GHG implications of water reuse through pumping groundwater and creek water, and compare this with gravity-fed canal irrigation in the Upper Pampanga River Integrated Irrigation System (UPRIIS) in the Philippines. Water productivity indicators show that water reuse contributes significantly to water productivity.

This web-based application was developed to assist the aggregation procedure, as well as the gathering and dissemination of information. The GGMN application enables the user to periodically produce online maps showing a regional change of groundwater variables in time.

IRD - Institut de Recherche pour le Développement (Research Institute for Development) - is a research organization based in France that is working with its partners in the South to address international development issues. Improving health, understanding social changes, and protecting the environment are the main pillars of its work towards achieving the Millennium Development Goals (MDGs). IRD work includes interdisciplinary scientific research, capacity building and nurturing innovation in more than fifty countries worldwide.
