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.

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.

The potential impacts of climate change on water resources and surface hydrology for Africa and Southern Africa have received considerable attention from hydrologists during the past decade. Climate change can affect groundwater levels, recharge and groundwater contribution to base flow. To assess these impacts, a climate change vulnerability index was developed. The index is used as a regional screening tool to identify areas that could experience possible changes in their groundwater resources as a result of climate change.

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.

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.

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. 

This report is divided in four main topics. The first presents a general analysis of links between the hydrological cycle and climate change, followed by the hydrological cycle in the Caribbean and its impact on water resources. It continues with an analysis of the possible impacts on groundwater due to sea-level rise and several aspects related to water management and finishes with different adaptation and mitigation options that should be implemented in each country's policies.
