The following are IWF presentations related to groundwater management:
Dr Stephen Foster
Dr Foster (Senior Adviser at GWP, Visiting Professor at UCL and Past President of IAH) provides a comprehensive overview of the main issues in the management of groundwater resources, examining the main technical considerations for a balanced policy.
Dr Chris Perry
As irrigation efficiency has improved in the Northern China Plain, water which would previously have contributed to groundwater recharge is instead being used elsewhere, with the consequences of increasing net abstractions and declining groundwater levels. The Chinese Government is promoting management of evapotranspiration (ET) and irrigation water use as a way of reversing this decline and restoring balance to aquifers.
Professor Alex Densmore
Dr Karen Villholth
Dr Karen Villholth, a Principal Researcher at IWMI’s Southern Africa Centre at Pretoria, delivers her lecture remotely online from Sri Lanka focusing on trends, and the potential, and constraints, for development. She states that the drivers for groundwater irrigation (GWI) in Africa mainly comprised: (1) groundwater provides a reliable and suitable irrigation source for smallholder, (2) Increasing market demand for horticulture crops, (3) Better low-cost pumps and wells (and better access to them), (4) Increasing attention in GWI (from governments and donors).
Richard Carter presented an array of facts and figures about population growth, irrigation and irrigated area, and groundwater resources and use in Sub-Saharan Africa, to set the scene for the DFID-NERC-ESRC UPGro (Unlocking the Potential of Groundwater for the poor) programme, running for 7 years and with a budget of £12M. He highlighted some of the differences in irrigation philosophy between Africa and Asia, and the need for research to improve our understanding of issues such as recharge process, surface water-groundwater interactions, and groundwater quality.
Professor Alan McDonald
Dr Roger Calow
China’s economic growth and success at feeding its huge population and lifting people out of poverty had been at the cost of environmental degradation, and its present attempts to reverse this whilst maintaining 90% self-sufficiency in future food production has created numerous challenges. In contrast, parts of sub-Saharan Africa could be described as islands of affluence in a sea of poverty as some countries, such as Ethiopia, experienced economic growth but not corresponding poverty reduction. This reflected a lack of past investments in water resource development, including irrigation, by governments and funding agencies, partly due to the paucity of good quality hydrometeorological data on which to base scheme designs.
