Irrigated rice cultivation is an important source of greenhouse gas emissions. Among the main gases, there are carbon dioxide, methane, and nitrous oxide, with emission each varying according to management crop, cultivar irrigation management. In this context, present study aimed quantify partial global warming potential (pGWP) measured by CH4 N2O emissions in conventional hybrid cultivars unde...

Sustaining irrigated agriculture to meet food production needs while maintaining aquatic ecosystems is at the heart of many policy debates in various parts of the world, especially in arid and semi-arid areas. Researchers and practitioners are increasingly calling for integrated approaches, and policy-makers are progressively supporting the inclusion of ecological and social aspects in water ma...

Agricultural systems pose many challenges and problems that can be formulated as optimization problems. Among these major challenges are crop selection and irrigation planning. That is, to decide on the proper set of crops to be cultivated and a proper irrigation scheme. Such decisions are made to achieve a certain objectives that typically include the maximization of net profit and/or the mini...

The increase in population growth and demand is rapidly depleting natural resources. Irrigation plays a vital role the productivity of agriculture, consuming no less than 75% fresh water utilization globally. Irrigation, being largest consumer across globe, needs refinements its process, because it implemented by individuals (farmers), use for irrigation not effective. To enhance management, fa...

Abstract Rice cultivation is important in China with over 29.33 million hm 2 of rice fields, producing 28.9% yields worldwide. fields are mass breeding sites for mosquitoes approximately 40 mosquito species found amongst them. Anopheles sinensis , lesteri and Culex tritaeniorhynchus the three main that fields. An. vectors malaria flat areas China, Cx. a vector Japanese B encephalitis. This revi...

Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...

This article takes issue with Stephen Lansing's bottom-up model of Balinese irrigation management. Based on archival research and extensive fieldwork in the former south Balinese kingdom of Mengwi, it is argued that in pre-colonial days large scale irrigation depended largely on dynastic involvement. During the colonial period (1906-1942) the Dutch took over the role of regional irrigation mana...

Since the 1970's, a large number of individual field studies of diverse irrigation systems have been completed in Nepal. Some of these studies were undertaken by masters or doctoral students and are based on extensive periods of time in the field. Others were written on the basis of shorter periods in the field: rapid rural appraisals, brief reports, and field-site visits by expatriate advisors...

To minimize movement of tritium into surface waters at the Mixed Waste Management Facility at the Savannah River Site, tritiumcontaminated groundwater released to the surface along seeps in the hillside is being retained in a constructed pond and used to irrigate forest acreage that lies over the contaminated groundwater. Management of the application of tritium-contaminated irrigation water ne...

When addressing urban water problems, it is no longer adequate to consider issues of water supply, demand, disposal, and reuse independently. Innovative water management strategies and opportunities for water reuse can only be properly evaluated in the context of their interactions with the broader water system. An integrated linear deterministic optimization model is applied to Beirut, Lebanon...
