Unsustainable groundwater use for food production intensifies the impacts of climate change, and cost-effective adaptation responses ...

  • The viability of treated piggery wastewater for reuse in agricultural irrigation

    Background The swine production is a very important economic matter, occupying prominent position in the worldwide market. However, it appears as the greater impacting activity for the water resources. Researches point a swine manure production of 105.6 million m3/year in Brazil, which resulted in a piggery wastewater rich in solids, nutrients, heavy metals, and pathogens. Moreover, ...

  • Household water constraints and agricultural labour productivity in Tanzania

    While previous research has analysed the links between drinking water access and health, and to some extent between health and agriculture, the direct impact of household water access on agricultural productivity has hardly been studied. We address this research gap, using survey data from Tanzania. Regression models show that water access constraints significantly decrease labour productivity ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • Aerated biofilter with seasonally varied operation modes for the production of irrigation water

    Water reuse for agricultural irrigation can contribute to the conservation of valuable water resources and opens the possibility to reuse the wastewater's nutrients (N and P) at the same time. As irrigation is usually limited to vegetation periods, effluent requirements for treated wastewater may vary seasonally. A process concept for wastewater treatment with variable operation modes for the ...

  • Water efficiency of agricultural production in China: regional comparison from 1999 to 2002

    We apply stochastic frontier analysis (SFA) techniques to a provincial level data set to measure technical and water efficiency in China's agricultural production from 1999 to 2002. The determinants of the efficiencies are identified together with the physical determinant structure of the irrigation factor, which refers to the water use per irrigated land area. The study yields the following ...

  • Deficit irrigation optimization of cotton with aquacrop

    Given the current pressures to reduce irrigation water use, it is important to optimize the use of water in irrigated agriculture. This work was aimed at determining the optimum level of applied irrigation water (AIW) for cotton (Gossypium hirsutum L.) production in southern Spain under several climatic and agricultural policy scenarios. To generate the yield response to variations in AIW, we ...

  • Estimating water use efficiencies for water management reform in Southern Alberta irrigated agriculture

    Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...

  • Irrigation planning for sustainable rain-fed agriculture in the drought-prone Bundelkhand region of Madhya Pradesh, India

    The recent spells of recurrent and consecutive droughts in the Bundelkhand region in Central India have led to uncertain rain-fed agriculture and its sustainability. Adequate knowledge of starting dates and lengths of dry spells has a considerable importance in rain-fed agriculture, irrigation planning, and various decision-making processes. The long dry spells incur heavy costs to the affected ...

  • Pressure Measurement For Agricultural Applications

    A couple months ago we took a brief look at how the agriculture industry is turning to automation and data to help monitor product and resource levels, enabling farmers and ranchers to be proactive, rather reactive, about the needs and conditions of their businesses. We all agreed that there are plenty of opportunities for level measurement in the modern agriculture industry. But what of pressure ...

  • Irrigation challenges in the sub-humid US Mid-South

    Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

  • Net biome productivity of irrigated and rainfed maize–soybean rotations: modeling vs. Measurements

    Estimates of agricultural C sequestration require an understanding of how net ecosystem productivity (NEP) and net biome productivity (NBP) are affected by land use. Such estimates will most likely be made using mathematical models that have undergone well-constrained tests against field measurements of CO2 exchange as affected by management. We tested a hydraulically driven soil–plant–atmosphere ...

  • A policy option for valuing irrigation water in the dry areas

    Participants at the international conference on policies for water and food security in the dry areas, held in June 2013, agreed that, given the fast pace of depletion of groundwater, the issue of water valuation in the dry areas is no longer one of whether or not, but rather of how. Policies that have been or are perceived to have adverse effects on the cost of agricultural production or food ...
