Abstract

Expansion and intensification of irrigated agriculture in Pakistan has been driven by food security and export income needs, and is driving a massive increase in poorly managed groundwater use.
Our 4-year ACIAR project, which commenced in late 2016, uses a collaborative approach to develop tools and options for improved groundwater management and farming family livelihoods at selected case study sites. Central to this approach is engaging and enhancing researcher and irrigation department capacity in Pakistan to improve groundwater monitoring, modelling and management. Together, we have developed groundwater models for the Lower Bari Doab in Punjab and the Left Bank of Sukkur Barrage in Sindh to improve spatial and temporal understanding of the groundwater system, and to explore the impact of pumping, irrigation and climatic conditions on water level trends. The models are providing in-depth analysis of the water balance for estimating sustainable yield. For example, the Lower Bari Doab model suggests an average decline in water levels of 0.45m per year since 2009, a rate corroborated by our groundwater monitoring. Scenarios were also run using
historic time-series of climatic data from Oct 2010 to Sep 2047 (Pakistan at 100 years).
This project has taken the first steps towards building capacity to improve management of stressed groundwater resources in Pakistan. In the near future Pakistan will have to rethink how it is going to meet the challenges of lower river flows, overexploited groundwater aquifers, and increasing demand for water from all sectors of society, agriculture, industry and potable use.
