1. Assessment of Equity in Water Distribution at Watercourse Level and Its Impact on Water Productivity

Fiaz Hussain; Amir Iqbal

Volume 1, Issue 4 , Spring 2021, Pages 1-12

http://dx.doi.org/10.22034/wpj.2021.274829.1032

Abstract
  The impacts of water variation differ in their magnitude in different canal irrigation systems, mainly due to variations in water availability (timings and amounts), crop types and soil fertility status. These necessitates conducting site-specific research and studies to evaluate the impact of variations ...  Read More
