Mega irrigation projects always bring problems and sometimes it is not easy to solve it. Such a countries like Pakistan, total annual cost of crop losses from salinity in PAkistan have been estimated at between 15 and 55 billion rupees (Rs) per year. This is in addition to the Rs15 billion estimated to have been lost from the land that has been rendered unproductive. Drainage is extremely important in Sindh province, however, because of the lack of management and maintenance not only dugged drainage canals collapse... »»

Quality not quantity is the greatest threat to Asia's most important source of groundwater

For several years satellite measurements have found that groundwater levels are generally declining across the region as groundwater abstraction for agriculture increases. However, this current study, published online this week in Nature Geoscience, looked in much closer detail at how groundwater quality and quantity varies and found that the greatest threat to groundwater in the region is more likely to be from water quality problems than widespread depletion.


Disability, Disasters, and Resilience

People with Disabilities often fall in the blind spot of Disaster Risk Reduction (DRR) plans… of countries, provinces, municipalities, and villages. Through research, awareness-raising, advocacy, and training, efforts are afoot to change that. 


A borehole that lasts for a lifetime

Water supply systems fail for a number of reasons. One reason is that the borehole was not properly constructed in the first place. This short film explains the procedures needed to provide a good drilled water supply that can last for many years.

Journalist Joseph Abuje finds out whether the proposed sugar cane projects in the Tana Delta will be an economic opportunity for local communities or a humanitarian and ecological disaster


 

Salinization: A hazard in irrigated arid zones

The arid zone constitutes a naturally highly saline environment. Irrigated crop production in this zone enhances this natural propensity as it evapotranspires large amounts of water, and in the process concentrates large amounts of salt


 

 

Biological Rodent Control

Rodents are known to destroy between 5-10% of crops on average (pre-harvest). During periods of spike in rodent population, this figure can shoot up to 30%. Local knowledge of biological rodent control based on medicinal plants need to be tapped into urgently.
