Land gradient and configuration effects on yield, irrigation amount and irrigation water productivity in rice-wheat and maize-wheat cropping systems in Eastern India.

Agric Water Manag 2021 Sep;255:107036

International Rice Research Institute (IRRI), Los Baños, Laguna, The Philippines.

Laser land levelling is expanding rapidly in the rice-wheat (RW) and maize-wheat (MW) systems of the Indo-Gangetic Plains of India and Pakistan. Current practice is to level to zero (0%) gradient, whereas a small gradient (e.g. Read More

Reuse of treated water in European agriculture: Potential to address water scarcity under climate change.

Agric Water Manag 2021 May;251:106872

European Centre for Agricultural, Regional and Environmental Policy Research (EuroCARE), Bonn, Germany.

The use of reclaimed or treated water from urban wastewater treatment plants for irrigation has been proposed as an alternative water source to address water scarcity issues in Europe. In this paper using agro-economic modelling, we analyse if treated water available for agriculture has the potential to reduce freshwater abstraction and, consequently, water stress. Implementing exogenous treated water quantities as an additional water supply at NUTS 2 level in the CAPRI model, we found that treated water reuse is a possible alternative supply source to address water shortages with a very negligible effect on farmers' income and food production in the EU.

Achieving sustainable soil and water protection: The perspective of agricultural water price regulation on environmental protection.

Agric Water Manag 2021 Feb 20;245:106583. Epub 2020 Oct 20.

School of Economics and Management, Fuzhou University, Fuzhou 350108, China.

With the development of Chinese economy, more and more attention has been paid to environmental protection, the implementation of water price policy affects economic and environmental changes in China. This paper analyzes the impact of water price policy on agricultural land use and the scale of water pollution discharge in 240 cities in China between 2001 and 2017, by including data from China Urban Statistical Yearbook and China Land & Resources Almanac. The theoretical analysis of this study indicates that the optimal scale of pollution depends on the local initial endowment, economic investment capital and the marginal cost of environmental pollution caused by government's economic activities.

Understanding clients, providers and the institutional dimensions of irrigation services in developing countries: A study of water markets in Bangladesh.

Agric Water Manag 2019 Aug;222:242-253

SEP, CIMMYT, Mexico.

Bangladesh is one of the most densely populated nations that nonetheless has largely achieved staple self-sufficiency. This development has been enabled in part by the rapid proliferation of small-scale irrigation pumps that enabled double rice cropping, as well as by a competitive market system in which farmers purchase water at affordable fee-for-service prices from private irrigation pump owners. Excess groundwater abstraction in areas of high shallow tube-well density and increased fuel costs for pumping have however called into question the sustainability of Bangladesh's groundwater irrigation economy.

Soil water management practices (terraces) helped to mitigate the 2015 drought in Ethiopia.

Agric Water Manag 2018 May;204:11-16

CGIAR Standing Panel on Impact Assessment, ILRI, ​​P.O. Box 5689, Gurd Sholla Area, Addis Ababa, Ethiopia.

While the benefits of soil water management practices relative to soil erosion have been extensively documented, evidence regarding their effect on yields is inconclusive. Following a strong El-Niño, some regions of Ethiopia experienced major droughts during the 2015/16 agricultural season. Using the propensity scores method on a nationally representative survey in Ethiopia, this study investigates the effect of two widely adopted soil water management practices - terraces and contour bunds - on yields and assesses their potential to mitigate the effects of climate change.

Effects of the ridge mulched system on soil water and inorganic nitrogen distribution in the Loess Plateau of China.

Agric Water Manag 2018 Apr;203:277-288

Graduate School of Agriculture, Hokkaido University, Sapporo, 060-8589, Japan.

The semi-arid region of the Loess Plateau is typical of rain-fed agricultural production in Northwestern China. In this area, the ridge mulched system (RM) is a widely-used measure to increase crop yield. The purpose of this study was to investigate the effect of RM on soil water and inorganic nitrogen (N) distribution, and grain yield of maize ( L. Read More

Impacts of plastic film mulching on crop yields, soil water, nitrate, and organic carbon in Northwestern China: A meta-analysis.

Agric Water Manag 2018 Apr;202:166-173

Department of Sustainable Soils and Grassland Systems, Rothamsted Research, North Wyke, Devon, Okehampton, EX20 2SB, UK.

In order to increase crop yield in semi-arid and arid areas, plastic film mulching (PFM) is widely used in Northwestern China. To date, many studies have addressed the effects of PFM on soil physical and biochemical properties in rain-fed agriculture in Northwestern China, but the findings of different studies are often contradictory. Therefore, a comprehensive review of the impacts of PFM on soil water content, soil nutrients and food production is needed. Read More

Evaluation of new farming technologies in Ethiopia using the Integrated Decision Support System (IDSS).

Agric Water Manag 2017 Jan;180(Pt B):267-279

Blackland Research Center, Texas A&M AgriLife Research, Temple, TX, United States.

This study investigates multi-dimensional impacts of adopting new technology in agriculture at the farm/village and watershed scale in sub-Saharan Africa using the Integrated Decision Support System (IDSS). Application of IDSS as an integrated modeling tool helps solve complex issues in agricultural systems by simultaneously assessing production, environmental, economic, and nutritional consequences of adopting agricultural technologies for sustainable increases in food production and use of scarce natural resources. The IDSS approach was applied to the Amhara region of Ethiopia, where the scarcity of resources and agro-environmental consequences are critical to agricultural productivity of small farm, to analyze the impacts of alternative agricultural technology interventions.

Response of bean cultures' water use efficiency against climate warming in semiarid regions of China.

Agric Water Manag 2016 Jul;173:84-90

Ningxia Liupanshan Flower Research Institute, Longde, Ningxia 756300, China.

Farm crop growing and high efficiency water resource utilizing are directly influenced by global warming, and a new challenge will be given to food and water resource security. A simulation experiment by farm warming with infrared ray radiator was carried out, and the result showed photosynthesis of broad bean was significantly faster than transpiration during the seedling stage, ramifying stage, budding stage, blooming stage and podding stage when the temperate was increased by 0.5-1.
