Abstract:
... Inequalities in access are a major concern for the management of common pool resources. In the case of irrigation water, inequalities are often explained by spatial “head-ender/tail-ender” distinctions, determined by distance to the water source. However, inequalities in access are also produced by social relations and social institutions. Drawing from ethnographic research in Ağlasun, a rural tow ...

Abstract:
... The unsustainable use of irrigation water is one of the most serious environmental problems in coffee farming. Rapid expansion of sustainability certifications and adoption of advanced irrigation technologies are expected to promote more sustainable water use through changes in water management practices in coffee farming. However, there lacks empirical evidence on the effects of those certificati ...

Abstract:
... Mobile drip irrigation (MDI) system is interesting because it combines the efficiency of drip irrigation with the versatility of center-pivot irrigation; however, experimental information about clogging of MDI emitters caused by dragging of driplines on the ground and by solid particles in the irrigation water simultaneously are not presented to date in the literature. The objective of this resear ...

Abstract:
... Israel’s water and vegetative agriculture sectors are interdependent, as the latter constitutes the solution for wastewater disposal. We employ a dynamic mathematical programming model that captures this interdependence for evaluating the economic damage of irrigation water salinity under two strategies of blending water sources with different salinities: field blending, which enables farmers to a ...

Abstract:
... Hand-held hoses and watering cans are widely used by smallholder farmers to irrigate vegetables in Cambodia and Laos. Overwatering is common. Technology change (e.g., low-pressure drip irrigation) has been used to improve irrigation efficiency but can be unaffordable for many smallholder farmers. The purpose of this study was to identify an appropriate method of predicting crop water demand, devel ...

Abstract:
... An appropriate agricultural water-land nexus can help to effectively take advantage of limited water and land resources, which is of great significance for guaranteeing food security. An R index was proposed to evaluate the regional agricultural water-land nexus from a green-blue water perspective in the current paper. The effects of irrigation on the agricultural water-land nexus were revealed fo ...

Abstract:
... The potential for concentrated fertilizer to drive water recovery via forward osmosis has received increased attention in recent years. Questions remain however about the quantities of water that can be recovered from batch processes, and how significant recovery volumes are relative to the overall water balance of crops. In this study, we establish the thermodynamic and practical limits of recove ...

Abstract:
... Apart from some works dealing with potato tuber growth and nutritional composition in response to water supply, no study on the effects of irrigation water saving strategies has been found in the literature. This study aimed to investigate the effects of four irrigation regimes: I0 dry control, I1 irrigation during the whole cycle, I2 irrigation from tuber initiation up to 50% of tuber growth, I3 ...

Abstract:
... An integrated simulation-optimization framework is developed under uncertainty to enhance irrigation water productivity and control salinity in an arid area. A full fuzzy dependent linear fractional programming approach is formulated by incorporating fuzzy dependent-chance programming, fuzzy credibility-constrained programming and linear fractional programming within a general framework of irrigat ...

Abstract:
... The purpose of this study is to estimate the contribution of water-derived ¹³⁷Cs in the total activity of ¹³⁷Cs in brown rice collected from Minamisoma, Fukushima. Three different methods used for the estimation were: 1) the concentration ratio of ¹³⁷Cs from water to brown rice (CR–wₐₜₑᵣ–ᵣᵢcₑ), 2) mass balance ratio of the total activity of ¹³⁷Cs from water to brown rice (MB–wₐₜₑᵣ–ᵣᵢcₑ), and 3) th ...

AIMS: To gather data on agricultural practices in organic farms in Sao Paulo, Brazil, and evaluate their relationship with the microbiological characteristics of samples collected along the production chain. METHODS AND RESULTS: Practices data were based on field observations and interviews with farmers in 10 selected organic lettuce producing farms. Counts of Enterobacteriaceae and surveys for Sa ...

Abstract:
... Reliable short-term forecasts of Irrigation Water Demand (IWD) can provide useful information to help water supply system operators with day-to-day operating decisions. Forecasting IWD is a complex task due to different natural (soil, water, crop, and climate interactions) and behavioral (farmers’ decision-making) components of the irrigation process. So far, various approaches have been developed ...

Abstract:
... The type and amount of salt present in water determine the suitability of water for irrigation. The aim of this study was to determine the effects of different salt sources (SS) and different salinity levels (SLs) in irrigation water on photosynthetic capacity, emergence and seedling growth parameters of eight bean (Phaseolus vulgaris L.) genotypes (G). The experiment was designed as a three-facto ...

Abstract:
... In India, the majority of the population relies heavily on rice as it is their primary source of nutrition. Rice crop yield productivity depends on seasonal variations and mainly depends on hydrological conditions. Long-term water clogging in rice fields for an extended period causes crop flooding and reduces production in terms of quality and quantity. This study deals with the identification of ...
