| The oregano is a plant, rich in essential oil and very used as spice in the preparation of foods. The objective of this paper was to analyze the viability of irrigation for oregano in Presidente Prudente, São Paulo state, Brazil, including economic risk factors, their effect on irrigation total cost, as well as the different pumping kinds. The Monte Carlo simulation was utilized to study the economic factors: fixed cost, labor, maintenance, pumping and water. The use of irrigation for the oregano in the region of Presidente Prudente is indicated because of its economic feasibility and the reduced risks. The average values of the benefit/cost for all water depths tested were higher than 1, indicating viability. The use of irrigation promoted lower risks... |

| The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline. |

| The purpose of this report is to show the process of the intervention made through the implementation of the IWRM and Food Security Demonstration Project in Zambia. The report gives details of the project processes, showing the steps the project went through, the outcomes and its impact on the communities where it was implemented. The report is the result of a number of field visits made to the completed project sites, the sources of information have been; focus group meetings, interviews, discussions with key informants, beneficiaries the youth, male and female stakeholders and reviews of project activity reports, and direct observations. Therefore, what is presented here is a cumulative “factual and real time” opinion as to what has been observed and... |
