This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.

"Waterlogging and salinisation are major impediments to the sustainability of irrigated agriculture and livelihoods of farming families across the Indus Basin of Pakistan. About 6.3 million ha in Pakistan are affected by different levels and types of salinity. Nearly half of this area is under irrigated agriculture. The drive for higher cropping intensities coupled with the lack of adequate surface water supplies has caused farmers to use poor-quality groundwater as a supplemental source of irrigation. The large scale exploitation of poor quality groundwater has increased the risks of soil salinisation and sodicity. About 4.5 million ha are already affected by secondary salinisation of which about half are located in irrigated areas. Another 1 million ha is affected by water logging (Qureshi et al., 2008). In Punjab, about 20% of the land suffers from salinity and another 20 to 30% has high groundwater levels, due to over application of surface water. Soil salinity problems are particularly serious in Sindh province where some 70 to 80% of the soil is classified as moderately or severely saline (Smedema, 2000). The southern districts of Lower Sindh, Thatta and Badin are particularly vulnerable to salinity due to waterlogging and seawater intrusion in coastal agricultural areas. A holistic approach that incorporates the social, environmental, technical and economic aspects of salinity management is needed in Pakistan. Such an approach offers better prospects for identifying and exploring adaptation measures and building resilience for communities affected by salinity. This SRA has established the need for a holistic approach to salinity and water management, and has laid the basis for developing a shared understanding of the risks and opportunities for farming and coastal communities in salinity affected areas of the Indus Basin of Pakistan. Central to this is an understanding of the spatial and temporal dimensions of salinity in the landscape."--Website.
