Shanxi Farmers Embrace Modern Irrigation Methods to Adapt to Climate Change Read more about Shanxi Farmers Embrace Modern Irrigation Methods to Adapt to Climate Change “Managing groundwater is important not just because of overuse. Due to climate change, groundwater has become the solid buffer,” said Frank van Steenbergen, water resources specialist with MetaMeta Research. “Water saving is important. This project started with the idea that we would save water, and that is important because we overuse it.”
Can We Secure Asia's Water by 2050? Read more about Can We Secure Asia's Water by 2050? The International Water Management Institute emphasizes productive and sustainable water management as a business case for the planet, focusing on solutions that cut across sectors. While the challenges are varied and dynamic, there are equally extensive solutions that can be put in place.
Evolution of Irrigation Practices: Are Large Scale Irrigation Systems Still Relevant? Read more about Evolution of Irrigation Practices: Are Large Scale Irrigation Systems Still Relevant? Recent irrigation trends in South Asia show signs of slowdown in groundwater use. This paper examines the implications of this slowdown in private informal irrigation on farmers, and what this entails from the irrigation bureaucracies who may now find farmers develop renewed interest in their services.

Salinity Intrusion and its Impact on Groundwater Quality: Case Study in Downstream of Bentota River Basin, Sri Lanka Read more about Salinity Intrusion and its Impact on Groundwater Quality: Case Study in Downstream of Bentota River Basin, Sri Lanka This study addresses the problem of salinity inclusion in Bentota River Basin in Sri Lanka and its impact on the environment. The objectives of the study are to identify surface and groundwater quality variations due to the influence of sea water intrusion, and determine impact on groundwater quality in the surrounding area.
Focus on Evapotranspiration-Based Integrated Water Management in the Turpan Basin Read more about Focus on Evapotranspiration-Based Integrated Water Management in the Turpan Basin Prevention of groundwater over-draft is essential in the case of the People's Republic of China. As the potential of saving water lies in agriculture, there is a need to develop effective water-saving irrigation techniques. The remote sensing-based evapotranspiration monitoring technique is used as an example.
