Small-scale irrigation continues to cushion the food security gap in sub-Saharan Africa. Irrigation is largely governed by water availability, soil type and crop water requirements, among other factors. Thus, a study was conducted to assess the suitability of various water sources for irrigation in northern Ghana.
Consequently, Colorado farmers, politicians, and businesses developed sophisticated irrigation systems and complex laws for capturing, storing, and moving water from source to field. Beginnings Though irrigation in the West has been practiced for over a millennium, its continuous use in Colorado stems from the mid-1800s.
Irrigation, in turn, did not become feasible during the boom of canals and stream diversion in mining. Thus it was not until the 1860s that large scale, irrigated farming became common. When major rail construction ended in the early 1870s, Chinese laborers moved easily into agriculture, proving themselves skilled farm workers and enterprising ...
— Irrigated agriculture is adapting to viability challenges due to water contamination from mining in various ways. We explore the option of using crops that …
— The large surface of the Mining Waste module generates a greater WF than the HLP module, where it is important to note the classification water type that the …
Ore-Max was a pioneer in the application of drip irrigation to gold and copper mines in the late 1980's. Previously the mines had used sprinklers which had many environmental and production limitations which were …
— Irrigation also includes water that is used for pre-irrigation, frost protection, chemical application, weed control, field preparation, crop cooling, harvesting, dust suppression, and leaching salts from the root zone.
— Heavy metal accumulation in different cities stemmed from different sources, including weathering of parent materials, industrial wastes, sewage irrigation, and mining activities.
Need mining sprinklers? Look no further than the Big Gun® Sprinkler and Rotator® from Nelson Irrigation for highly effective mining dust control solutions.
— An irrigation controller is an essential part of the irrigation system and helps to achieve labour savings in addition to applying the required volume of irrigation water for a specified period leading to high efficiency in water, energy, and fertilizer use (Boman et al., 2018). Irrigation control strategies are divided into open-loop systems ...
— High-fluoride (F ⁻ ) deep groundwater in the vicinity of mining areas poses severe ecological risks. In this study, we aimed to characterize and reveal the seasonal distribution and influencing ...
Water use in the context of hard rock mining refers to process water that is necessary for routine functioning of the mine-mill complex, and not to incidental water such as excess …
— Positive matrix factorization and Monte Carlo simulation were used to evaluate the ecological and human health risks of heavy metals. The research findings indicate that heavy metal pollution was the most severe at the depth of 20–40 cm in soils, with local heavy metal pollution resulting from mining and sewage irrigation.
— Agriculture is a major user of ground and surface water in the United States, and irrigation has enhanced both the productivity and profitability of the agricultural sector. According to the 2017 Census of Agriculture, farms with some form of irrigation accounted for more than 54 percent of the total value of U.S. crop sales, while irrigated land …
— After AMD irrigation in mining areas, heavy metals are distributed among soil layers, but the influencing factors and mechanisms remain unclear. AMD contamination of surrounding soil is primarily attributed to surface runoff and irrigation and causes significant environmental degradation. A laboratory soil column experiment was conducted to ...
In 2008, a maize underproduction disaster occurred in the Xianyu village after irrigation using the coal mining water from the Xingdong Mine, China. This disaster resulted in about 40 hectare maize underproduction and 20 hectare total loss of the maize yields. In order to study the reason, a total o …
— Throughout the world, irrigation (water for agriculture, or growing crops) is probably the most important use of water (except for drinking and washing a smelly dog, perhaps). Irrigation water is essential for keeping fruits, vegetables, and grains growing to feed the world's population, and this has been a constant for thousands of years.
— According to their report, the major uses for water are irrigation (30% of total use), livestock (23.5% of total use) and mining (12.7% of total use), with mining expected to draw more water in the future. The Tuul and the Orkhon basins draw the most water, at 27.6% and 13.5% of total use.
— Irrigation is a lynchpin of rural development strategies and a key input to improving productivity and farm incomes, the key source of livelihood for the majority of the world's poor. ... mining, industry, hydroelectricity generation, and a rising population (USGCRP (U.S Global Change Research Program), 2017, de Fraiture et al., 2010).
Artisanal and small-scale mining and irrigation-based farming are the main. This article aims to show that competing demands on environmental resources have, more often than not, exacerbated vulnerability of poor rural agricultural communities. Artisanal and small-scale mining and irrigation-based farming are the main

This paper reviews the impact of illegal mining on water resources for irrigation and domestic application in Ghana. It was carried out by reviewing literature and media information as well as interviews and observation of small scale mining activities in mining communities especially illegal mining popularly called galamsey in Ghana. It was
— Leach mining operations generally choose between using sprinkler irrigation or drip irrigation systems. The biggest issue with sprinkler systems is that toxic chemicals can be spread beyond the mining site due to wind, whereas a drip irrigation systems ensures that all lixiviant is applied directly to the heap.
— Total water use, by category of use, 2015. Thermoelectric power and irrigation remained the two largest uses of water in 2015, and total withdrawals decreased for thermoelectric power but increased for irrigation.; Withdrawals for thermoelectric power were 133 Bgal/d in 2015 and represented the lowest levels since before 1970.; Irrigation …
