Abstract
Effectiveness of Sodium Bentonite Clay for Reducing Seepages from Earthen Rainwater Harvesting Ponds
Highlights
Arid lands constitute around 80% of the world’s agricultural land where livelihood entirely depends on rainwater
The purpose of this study is to determine the effectiveness of Sodium Bentonite clay as a lining material for rainwater harvesting ponds
The station is operated by Pakistan Council of Research in Water Resources (PCRWR)
Summary
Arid lands constitute around 80% of the world’s agricultural land where livelihood entirely depends on rainwater. These areas contribute at least two-third of global food production [1]. About 70% of the world’s poor people live in these areas These areas have a great potential to contribute to livelihood and food security of the poorest due to:. (ii) largely belong to poor communities and (iii) large area available for out-scaling of promising interventions. These lands need to be exploited to meet the ever-increasing food and fiber demands [2]. Management and its use is a common practice for drinking and farming, either directly tapping the runoff or storing it in surface or subsurface reservoirs [4]
