2024年11月7日 · Recent research looking at key snowmelt-driven watersheds access the West estimated that 61% of wetlands are associated with irrigated agriculture. Many of these are temporary and seasonal wetlands sustained by flood irrigation in areas where natural wetlands were once historically located.

The tool allows users to map flood-irrigated grass hay agriculture across the western United States, as well as the types of wetlands it provides throughout the year. This spatial tool is a great companion for the strategic conservation of agricultural lands and …

2023年6月20日 · Irrigation accounts for ~70% of global freshwater withdrawals and ~90% of consumptive water use, driving myriad Earth system impacts. In this Review, we summarize how irrigation currently...

Proper irrigation management is required to maintain adequate soil moisture in the crop root zone for healthy plant growth and optimum yield. This publication provides information on the potentially negative impacts excess water or wet soil can have on crop growth and yield, soil oxygen, and the carbon dioxide concentration balance.

2024年10月3日 · In most humid regions, irrigated area is larger in dry years, whereas in more arid regions like Spain, it is larger in wet years. The largest irrigated area across Europe occurred in dry...

33 Land use land cover change affects weather and climate. This paper quantifies land-34 atmosphere interactions over irrigated and non-irrigated land uses during the Great Plains 35 Irrigation Experiment (GRAINEX). Three coupling metrics were used to quantify some land-36 atmosphere interactions as it relates to convection. They include: the ...

Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world.

2025年1月1日 · We hypothesized that the continuous moist soil water pattern provided by suitable continuous irrigation technology, compared with the continuous dry and wet alternations during the growth period, could improve soil physicochemical characteristics, maintain good soil structure and enhance soil bacterial community, and ultimately obtain higher ...

2 天之前 · But despite these contributions, our wetlands face multiple threats. Since 1700, approximately 87% of the world’s wetlands have been lost, with 64% of this loss occurring since 1900. Between 1970 and 2015, there was a 35% reduction in global wetland area, indicating that wetlands are disappearing three times faster than forests.. Land-use change is the biggest driver of wetland degradation.

2025年1月26日 · Drechsel et al. 7 estimated that globally roughly 30 million hectares of agricultural land are irrigated with untreated, partially treated, or diluted wastewater, by far exceeding the area of ...
