Estimating productivity of water at different spatial scales using simulation modeling
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Droogers,   Peter; Kite,   Geoff.
A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Indicators for comparing performance of irrigated agricultural systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Molden,   David J.; Sakthivadivel,   Ramasamy; Perry,   Christopher J.; de Fraiture,   Charlotte; Kloezen,   Wim H.
Outlines IWMI's external and other comparative performance indicators that allow for analysis of irrigation performance across systems. The purpose of these indicators is to understand the current situation with respect to productive utilization of land and water, to compare relative performance of systems, and to identify where performance can be improved.

Accounting for water use and productivity
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Molden,   David J.
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and  increasing water...

Impact of management interventions on the performance of five irrigation schemes in Sri Lanka
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Imbulana,   K.A.U.S.; Merrey,   Douglas J.
This working paper is the outcome of a data collection process initiated under the advice of Dr. Shigeo Yashima of the International Irrigation Management Institute (IIMI). The objective of this data collection process was to make a preliminary assessment of irrigation performance in Sri Lanka using irrigation systems with different backgrounds to identify areas for further research.

Institutional design principles for accountability in large irrigation systems.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Merrey,   Douglas J.
Argues that single irrigation systems managed by autonomous system-specific organizations accountable to their customers, perform better and are more sustainable than those managed by agencies dependent on the government, or by agencies responsible for multiple systems. Selected cases are reviewed and the plausibility of this hypothesis established. General recommendations are made for policy makers designing irrigation reform programs.

Participatory rural appraisal for irrigation management research: lessons from IIMI's experience
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gosselink,   Paul; Strosser,   Pierre.
The increasing international awareness about the strengths of participatory approaches and methods for research and development has led international development banks, NGOs, donors and research and training institutes to adopt Participatory Rural Appraisal (PRA) and other participatory approaches to implement new projects and programs. At IIMI, PRA approaches and methods have also been incorporated in a number of research activities. The present Working Paper explores the opportunities of PRA in irrigation management research through an analysis of selected case studies in which IIMI attempted to practice the PRA approach.

Evaluation of the Heat and Energy Performance of a Datacenter Using a New Efficiency Index: Energy Usage Effectiveness Design – EUED.
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Santos,Alexandre F.; Gaspar,Pedro D.; Souza,Heraldo J.L. de.
Abstract Data Centers are growing steadily worldwide, and they are expected to continue growing up to 53% in 2020. Energy efficiency, in high power consumption, is a key venue. There are methodologies to measure this efficiency, one example is using the PUE (Power Usage Effectiveness) index. In this paper is proposed a new index for measuring efficiency at the design stage, the EUED (Energy Usage Effectiveness Design). This index allows to evaluate systems using “free cooling” and adiabatic system. A comparison is performed considering the equipment in the worst situation. The thermodynamics parameter enthalpy is used to calculate the results. This new methodology allows to determine differences between the cities of São Paulo and Curitiba (1.21%) and...
