  • Simulating the Effect of Climate Change on Agriculture

    Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2 While climate change is expected to affect agriculture and reduce crop yields, the complete ...

  • Reducing agriculture’s water footprint

    Decentralized Water Reuse Can Help Preserve Sources of Fresh Water As the world population grows, so does the demand for food and the need to grow more crops. In many regions of the world, water has become a scarce resource, with supplies affected by climatic changes. Not only does water scarcity limit farmers’ ability to irrigate their crops, but overdrawing groundwater supplies ...

  • Are agricultural chemicals affecting our water?

    With the rate at which modern towns and cities expand it’s inevitable that the volume of separation between agricultural facilities and highly populated areas is shrinking. The loss of these areas can have a lasting impact, particularly when it comes to our water supplies. From an ...

  • 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). ...

  • Direct Potable Reuse: Benefits for Public Water Supplies, Agriculture, the Environment and Energy Conservation

    INTRODUCTION Direct potable reuse (DPR), in which purified municipal wastewater is introduced into a water treatment plant intake or directly into the water distribution system, is becoming an increasingly attractive alternative to developing new water sources (Tchobanoglous et al., 2011). The rationale for DPR is based on the technical ability to reliably produce purified water that ...

  • 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 ...

  • Evaluation of water demand and supply in the south of Iraq

    This paper presents results from the first study that focuses on water resources availability and demand for different purposes in the four oil-rich provinces of southern Iraq. The region accounts for 23% of the surface area and 18% of the country's population, but holds 88% of its oil. A water shortage of 430 Mm3/year for 2010 is estimated for this region where irrigation accounts for 81% of ...

  • China: agricultural production and groundwater

    As in many parts of the People’s Republic of China, Shanxi Province is experiencing reduced water security for the agriculture sector. Changing climate conditions, including reduced rainfall, are increasing reliance on groundwater resources in the province. Unsustainable groundwater use for food production intensifies the impacts of climate change, and cost-effective adaptation responses ...

  • Conjunctive effect of water productivity and cultivation pattern on agricultural water management

    Agricultural water resources are scarce in Iran, and agricultural water management is essential to overcome this limitation. Determination of the water productivity index (WP) using the methods of optimization of cropping patterns and optimal water allocation is the most effective tool in water management in the agricultural sector. In this study, a non-linear optimization model was used to ...

  • 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 ...

  • The water-energy-climate nexus in Mexico`s agricultural use of groundwater

    Human water use is a main driver of the spatial distribution and temporal availability of water resources globally (Vörösmarty et al. 2000). In the specific case of groundwater sources there are three interlinked processes that drive water balances in diverse regions globally: 1) intensification of groundwater irrigation, 2) electrical energy supply for agriculture, and 3) climatic ...

  • Agricultural water conservation and efficiency in California: a special focus on the Delta

    The Sacramento-San Joaquin Delta is a critical resource. Almost half of the water used for California’s agriculture comes from rivers that once flowed to the Delta and more than half of Californians rely on water conveyed through the Delta for at least some of their water supply. The Delta also provides habitat for 700 native plant and animal species. This important region is now in a serious, ...

  • Impact of agricultural water reallocation on crop yield and revenue: a case study in China

    Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

  • One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas

    All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the ...

  • Impacts on the utilization degree of canal water caused by agricultural water reallocation: a case study from China

    Our study area in the People's Victory Canal Irrigation District (PVCID), which is downstream of the Yellow River in China, has been undergoing agricultural water transfer to the city for municipal uses. Water supply condition data from PVCID are used to analyze the impacts of water reallocation on agricultural water supply quality, and field survey data in PVCID are used to examine the ...

  • Water reclamation and intersectoral water transfer between agriculture and cities – a FAO economic wastewater study

    Cost–benefit studies on replacing conventional agricultural water resources with reclaimed water in favour of cities are still rare. Some results of a study under auspices of the Food and Agriculture Organisation (FAO) are presented. By means of an illustrative example at Lobregat River basin in Spain, it could be proved that reclaimed water reuse and intersectoral water transfer can result in ...

  • Potential water savings associated with agricultural water efficiency improvements: a case study of California, USA

    This study analyzes the potential for water savings from irrigation efficiency improvements in California, USA. We model water savings associated with three efficiency scenarios in wet, average and dry water years. The ‘efficient irrigation technology’ scenario shifts a fraction of the crops from flood irrigation to sprinkler and drip systems; the ‘improved irrigation scheduling’ scenario uses ...

  • Everglades Agricultural Area Reservoir A-1 Management of Runoff for Everglades Restoration and Agricultural Irrigation

    THE PROBLEMIncreased development in central and south Florida has altered the natural drainage pattern of the Florida Everglades National Park (Everglades). This alteration has resulted in excess water during the wet season and insufficient water flowing through the ecosystem during the dry season, increased water supply demands, degrading water quality, and declining estuary health and wading ...

  • Climate Smart Agriculture: Zambia’s Strategy to Reduce Emissions

    The agricultural sector is believed to be the backbone of the Zambian economy thereby alleviating problems associated with poverty and food security. The development of the sector is viewed as one sustainable way of economic growth and ‘Eradicating Extreme Poverty and Hunger’ which is goal number one of the Millennium Development Goals (UN, 2000). The sector contributes to the growth ...
