Center for Agricultural Water Research in China, China Agricultural University, Beijing 100083, China.

There is an urgent need for scientific management of agricultural water and land resources to cope with global warming and water shortages. Therefore, a stochastic multi-objective non-linear programming model was established under the society-economy-ecology framework in this study, which is capable of (1) considering the carbon sink function of farmland vegetation and the carbon emissions produced from the input of production materials; (2) dealing with the potential impact of agricultural water use on ecology by the indexes of water scarcity and degradation footprint (3) weighing the conflicts and contradictions among different developing targets with economic benefits, and water productivity as well as ecological considerations; (4) obtaining the planting structure, irrigation water allocation schemes and irrigation schedules. In order to verify the applicability and effectiveness of the model, it was applied to Huangyang Irrigation District in Shiyang River Basin, northwest China. Read More

Intelligent Control of Agricultural Irrigation through Water Demand Prediction Based on Artificial Neural Network.

Comput Intell Neurosci 2021 23;2021:7414949. Epub 2021 Nov 23.

Institute of Urban and Rural Construction, Agricultural University of Hebei, Baoding 071001, China.

In irrigated areas, the intelligent management and scientific decision-making of agricultural irrigation are premised on the accurate estimation of the ecological water demand for different crops under different spatiotemporal conditions. However, the existing estimation methods are blind, slow, or inaccurate, compared with the index values of the water demand collected in real time from irrigated areas. To solve the problem, this paper innovatively introduces the spatiotemporal features of ecological water demand to the forecast of future water demand by integrating an artificial neural network (ANN) for water demand prediction with the prediction indices of water demand.

Crustacean Fauna of the Aral Sea and its Relation to Ichthyofauna During the Modern Regression Crisis and Efforts at Restoration.

Zool Stud 2021 31;60:e25. Epub 2021 May 31.

Section of Marine Biology, Department of Biology, University of Copenhagen, Universitetsparken 4DK-2100 Copenhagen, Denmark. E-mail: (Høeg).

The regression and salinization of the Aral Sea, largely caused by water diversion for irrigation, is among the most severe ecological disasters of the 20th century, and has had severe health and economic consequences for the local population. Introductions of alien species to enhance commercial fisheries before the regression had already impacted the ecology of this system. Crustaceans made up about one-quarter of the original metazoan species and constituted the principal food for native and introduced fish. Read More

Experimental study on infiltration pattern: opportunities for sustainable management in the Northern region of India.

Water Sci Technol 2021 Nov;84(10-11):2675-2685

Civil and Environmental Engineering, University of the West Indies, St Augustine, Trinidad.

The infiltration process plays a key role in designing groundwater recharge, irrigation, and drainage systems, and contamination evaluation is controlled by numerous factors, among which soil physical properties and land use & land cover (LULC) are the prime factors. A comprehensive understanding of the spatial water infiltration characteristics over the soil, which is site-specific and more complex due to non-uniformity, could enhance the agriculture water use efficiency and mitigate water-related issues. The present study deals with the measurement of field infiltration characteristics using a mini disc infiltrometer in all 24 blocks of Gaya district, Bihar, which covers a wide spectrum of soil types.

Department of Computer Science, College of Computer Science and Information Sciences, Majmaah University, Al-Majmaah, Saudi Arabia.

The amount of water taken from non-renewable resources such as aquifers to fulfill irrigation requirements is rarely monitored, putting sustainable agriculture under threat in the face of changing climate. In the present research, an attempt was made to apply multi-sensor (Landsat suite, GRACE, GRACE-FO) satellite data to monitor spatiotemporal evolution of agriculture for the Al-Qassim region, Kingdom of Saudi Arabia (KSA). For this purpose, time series of NDVI (Normalized Difference Vegetation Index), SAVI (Soil-Adjusted Vegetation Index), and MSAVI2 (Modified Soil-Adjusted Vegetation 2) was utilized to assess vegetation pattern change in the study area.

Tomas Bata Univesity in Zlín, Faculty of Management and Economics, Mostní 5139, 760 01, Zlín, Czech Republic.

The economics of producing energy-valuable gases by fermenting phytomass is deteriorated by the costs associated with waste management of highly diluted (typically 95% water) fermentation residues (FR). Previously, no better solution was known than to plough FR into the arable land and claim that it is an irrigation with soil improving and fertilizing effect. However, farmers soon realized that FR organic matter is of little agronomic value and nutrients are at agronomically insignificant levels. Read More

Removal of Biomass and Nutrients by Weeds and Direct-Seeded Rice under Conservation Agriculture in Light-Textured Soils of North-Western India.

Plants (Basel) 2021 Nov 11;10(11). Epub 2021 Nov 11.

Department of Agronomy, Bangladesh Wheat and Maize Research Institute, Dinajpur 5200, Bangladesh.

The escalating scarcity of irrigation water, transplantation of rice on light-textured soils and labour cost acted as major drivers for the transition towards direct-seeded rice (DSR) cultivation from the conventionally flooded transplanting system. Despite these advantages, DSR is a challenge in light texture soil due to heavy weed infestation and a slight decline in crop yield. The weeds compete for nutrients and have an adverse effect on the growth and yield of crops. Read More
