Volumetric Water Pricing, Charles M. Burt

BioResource and Agricultural Engineering

This document discusses the concept of volumetric pricing for irrigation water, including:

1. The justification for paying volumetrically

2. The challenge of charging volumetrically

3. Characteristics of volumetric charges and influencing factors

4. Examples of irrigation projects with volumetric charges

5. A summary of necessary conditions for volumetric billing

Monitoring And Evaluation (M&E) Of Capacity Development For Irrigation Modernization, Charles M. Burt

BioResource and Agricultural Engineering

Effective capacity development monitoring and evaluation (M&E) depends first upon targeted capacity development programs, with well-defined and attainable objectives that can be evaluated after completion of the program. This paper focuses on capacity development related to technical issues of irrigation modernization.

ITRC performs diagnostic research on irrigation projects and field irrigation systems in advance of developing targeted capacity development programs. If the capacity development is appropriate, and if it is targeted in both content and to specific audiences, one can expect an eventual improvement in post-capacity-building performance. ITRC has found that the improvements are incremental, and often require substantial changes …

Surface Drip Tape Irrigation Systems As An Alternative To Sdi For Field And Row Crops, Charles M. Burt

BioResource and Agricultural Engineering

In recent years, new equipment and techniques developed by farmers and private industry have improved the suitability of surface drip tape as an alternative to subsurface drip irrigation (SDI) for field crops and vegetable crops in highly mechanized farming. Retrievable drip tape systems now lack many of the disadvantages of SDI, yet provide the advantages typically expected from drip irrigation. Tape retrieval practices have now reached well beyond the theoretical realm to the point that they dominate drip systems for cauliflower, lettuce, celery, and broccoli on the Central Coast of California. It is expected that drip design and practices will …
