Diagnostic Analysis (DA) is a methodologyfor assessing and understanding the performance of anagricultural system. This analysis is thefirst step in a large system change process, known asthe Management Improvement Program (MIP), whoseobjective is to improve the performance of the agricultural system.A group of Federal andstate of Arizona agencies agreed to apply the MIPmethodology in a western U.S. setting. The purpose of theapplication was to test the applicability of the MIPapproach and to re...

A detailed Diagnostic Analysis (DA)was performed on an irrigation district in CentralArizona as part of a Management Improvement Program(MIP). The DA was conducted by an interdisciplinaryteam who focused their findings on performance of theirrigated agricultural system, on- and off-farm,rather than on disciplines. This paper reports on thefindings related to on-farm management. Specificfindings are presented relative to farm water use,soil sustainability, the interactions between the farmirrigat...

The Management Improvement Program, a process based on Organizational De- velopment principles and methods, was applied to an irrigated agricultural system in Arizona, USA. The MIP seeks to improve management and performance of the agricultural system through structured diagnosis, planning, and implementation activities with the participation of system stakeholders. An equally important objective of the demonstration project was to identify strengths and shortcomings of the MIP methodology and t...

Enhanced long-term management ofnatural resources, farmer profitability, and overallsocial well-being are essential to sustainableirrigated agriculture. Because these objectives oftenseem to conflict, all agriculturalstakeholders – farmers, irrigation districts, supportand regulatory government agencies, and otherinterested parties – need to interact proactively toidentify and address common needs. To this end, theManagement Improvement Program (MIP) was tested in theMaricopa-Stanfield Irrigatio...

A Diagnostic Analysis was conducted in the service area of theMaricopa-Stanfield Irrigation and Drainage District in Arizona,USA. The study was an initial step in a managed change process,named Management Improvement Program (MIP), aimed at improvingthe performance of the area's irrigated agricultural system. Partof the Diagnostic Analysis study focused on the performance ofthe irrigation district's water delivery service. The studyidentified areas of high and low water delivery performance,fact...

In 1991, the USDA-Agricultural Research Service U. S. Water Conservation Laboratory (USWCL) and a coalition of federal, state, and county agencies initiated a project to develop and test the Management Improvement Program (MIP) as a methodology for improving the performance of an irrigated agricultural area. The MIP is a process that aims to involve multiple stakeholders in the identification, development, and implementation of plans to strengthen the sustainability of the system. A demonstratio...

An interagency Management Improvement Program (MIP) has been initiated to develop, apply, and evaluate the MIP methodology as a way to improve resource management and organizational effectiveness in supporting irrigated agriculture. The Diagnostic Analysis (DA), the first phase of a demonstration MIP underway in an irrigation district in central Arizona, is described along with a brief discussion of the DA findings.
Farmers who receive water from irrigation districts prefer deliveries that are flexible but accurate in frequency, rate, and duration. To study how well an irrigation district was able to match deliveries to farmers' orders and to account for deliveries, water deliveries along two monitored lateral canals were compared to the orders and bills for those events. The data showed that farmers complied with the official ordering policy about half the time, and were more likely to follow the policy du...

An irrigation district in southwestern Arizona was studied to assess the performance of its water delivery system. Data were obtained through monitoring of lateral canals, examining water order reports and bills, and conducting a diagnostic analysis of the water delivery and on-farm irrigation systems through interviews. A number of differences between official andde facto district operating policies were found. These policies had changed over the years and provided far more flexibility and bett...

Deep percolation flow below agricultural and can transport nitrate and pesticide residues to underlying groundwater. Irrigated agriculture in dry climates can also contaminate groundwater with salt from irrigation water and with trace elements such as selenium leached from the vadose zone. Groundwater contamination by agricultural chemicals can be minimized by using best management practices (BMPs) for crop production (including low-input sustainable agriculture or other source control) and for ...
