Yield Enhancement through a Low-Cost Irrigation System for Groundnut

Delivering a low-cost, reliable drip irrigation filtration system for micro-irrigation in developing countries

The cylindrical filters presently used in drip irrigation systems frequently clog, increasing pressure loss and lowering the flow rate through the filters. This work investigates alternative filtration strategies that increase the reliability of, and are compatible with, existing systems. To test different filtration strategies, a drip irrigation test setup was built to measure the pressure los...

Reimagining cost recovery in Pakistan's irrigation system through willingness-to-pay estimates for irrigation water from a discrete choice experiment

It is widely argued that farmers are unwilling to pay adequate fees for surface water irrigation to recover the costs associated with maintenance and improvement of delivery systems. In this paper, we use a discrete choice experiment to study farmer preferences for irrigation characteristics along two branch canals in Punjab Province in eastern Pakistan. We find that farmers are generally willi...

A low cost photoelectron yield setup for surface process monitoring

Automated Landslide Monitoring through a Low-Cost Stereo Vision System

In this paper we introduce an inexpensive yet efficient photogrammetry system that takes advantage of state of art computer vision techniques to monitor large natural environments. Specifically, our system provides a precise evaluation of the terrain flow in wide landslides through optical flow applied to 2D image sequences and a back-projection of the resulting motion gradients to a 3D model o...
