  • Technical coefficients of direct use of water in monetary terms for agriculture and urban water use

    The San Francisco Integration Project is a Brazilian government project aiming to bring water to the semiarid region of the northeast. The project provides funding for two diversions of the San Francisco River, supplementing the supply of local water in four Brazilian states. The Piranhas-Açú and Jaguaribe basins will become the largest recipients of these water deliveries. In this paper, we ...

  • Watering Scarcity: Private investment opportunities in agricultural water use efficiency

    This report was prepared by Rabobank in collaboration with the World Resources Institute. In many regions around the world, demand for fresh water now outstrips renewable supplies. Water scarcity is projected to worsen considerably due to a combination of factors such as population increase, higher incomes and changing lifestyles, pollution, and climate change. Agriculture is by far the biggest ...

  • Changing mechanisms of agricultural water use in the urbanization and industrialization of China

    The rapid urbanization and industrialization of China in recent years has presented serious challenges for the country in guaranteeing the preservation of agricultural water resources. This study selected four areas in China, each with different water resource and social development conditions. The relationship between the processes of urbanization and industrialization and recent agricultural ...

  • 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 ...

  • Reuse: Agriculture

    Agronomic and water quality considerations Water use for agricultural irrigation is the largest component of water use in most countries and is more than 70% of human water use in drier countries. Use of recycled water for irrigation requires consideration of soil types, groundwater levels, soil and water chemistry, nutrient loads, limits on chemicals, the salt tolerance of ...

  • Agricultural water vulnerability in rural Iran

    Water is an important factor of production and livelihood support in rural communities. Meanwhile, water shortage is a virtually common feature in many arid and semi-arid countries. It is also projected that water stress will be exacerbated in such regions because of climate change. The cumulative effects of these stressors can potentially increase agricultural water vulnerability (AWV). ...

  • The localization of agriculture

    In the United States, there has been a surge of interest in eating fresh local foods, corresponding with mounting concerns about the climate effects of consuming food from distant places and about the obesity and other health problems associated with junk food diets. This is reflected in the rise in urban gardening, school gardening, and farmers’ markets. With the fast-growing local foods ...

  • The impact of public policy on conservation tillage in US agriculture

    A number of policy tools are used to reduce soil erosion from agricultural lands in the USA, including education and technical assistance, financial assistance, land retirement, and conservation compliance requirements. Education and technical assistance by public and private sources can be effective in promoting the adoption of conservation tillage by farmers for whom that practice will be ...

  • Use of vermicomposting biotechnology for recycling organic wastes in agriculture

    Recent trend of declining sustainability in agricultural production is appearing as a major threat to most of the Asian countries. To combat the situation, increasing importance is now being paid on incorporation of organic materials for rejuvenating the health condition and, hence, the productivity of these soils. Large scale availability of conventional organic manures being a big problem ...

  • Opportunities for saving and reallocating agricultural water to alleviate water scarcity

    As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At ...

  • Setting water quality criteria for agricultural water reuse purposes

    The use of reclaimed water for agricultural irrigation is practiced worldwide and will increase in the future. The definition of water quality limits is a useful instrument for the assessment of water quality regarding its suitability for irrigation purposes and the performance of wastewater treatment steps. This study elaborates water quality objectives for a water reuse project in a setting ...

  • Optimisation of water pricing in the Greek agricultural sector

    The agricultural sector is a dominant one in the Greek economy and thus attracts the scientific interest. Water is significant for a cultivation’s productivity and consequently for the agricultural income. Water pricing as a result has become a subject of extended study. The present study refers to the Greek agricultural economy and suggests a macroeconomic model, through which the optimisation ...

  • Water for agriculture and the environment: the ultimate trade-off

    Global population is projected to increase over year 2000 levels by 30% in 2025 and by 50% in 2050. Producing sufficient food to feed a more populous Earth will be a challenge requiring additional developed water supplies. Existing supplies are unevenly distributed around the planet. Some developing countries lack sufficient water to grow the food necessary to feed the growing population. With ...

  • Balancing Agricultural, Urban, and Environmental Water Needs in Water Resources

    The Lower Colorado River Authority (LCRA) – San Antonio Water System (SAWS) Water Project is a plan to conserve water, develop groundwater, and capture excess and unused river flows to meet future water needs for two neighboring regions in Texas. Agricultural and other rural water needs would be met on a more reliable basis in the lower Colorado River basin through water conservation, surface ...

  • Moral drought: The ethics of water use

    Water has been called the berth of life as it performs basic ecological functions in every environment. Many relevant water properties are not discernible to the human senses: microbes are invisible; colour and taste often give little indication of water composition or potability. For this reason, technological deficiencies in water management are often responsible for disease, mortality and ...
