Previous research on the effects of drought vegetation productivity seldom distinguished different responses ecosystems to under management practices and land use systems. Studies investigating whether irrigation can buffer negative impacts usually used discontinuous yield data in distribution. In this study, trends farmlands drylands northern China (DNC) from 2000 2018 were studied using self-...

Because of its unique chemical structure, water dissolves almost any substance and thus is easily polluted. Environmental pollution continues to escalate in emerging economies such as in Sri Lanka. This is aggravated by anthropogenic activities, including deforestation, soil erosion, and irresponsible use of agrochemicals, and overuse of phosphate fertiliser. The latter has led to leaching of l...

The estimation of evapotranspiration of blue water (ETb) from farmlands, due to irrigation, is crucial to improve water management, especially in regions where water resources are scarce. Large scale ETb was previously obtained, based on the differences between remote sensing derived actual ET and values simulated from the Global Land Data Assimilation System (GLDAS). In this paper, we improve ...

Wastewater contains poisonous metals which can be moved and accumulated in plants before entering the human body through food chain. The aim of this research was to investigate concentrations toxic such as Nickel (Ni), lead (Pb), copper (Cu) wastewater, celery plant farmlands soils Duhok city Kurdistan of, Iraq. heavy accumulation Celery plants, soil water samples were analyzed by using an atom...

Agricultural irrigation is a primary user for freshwater withdrawal. Irrigation plays an important role in crop production, as it provides the benefit of reducing effects prolonged dryness and erratic precipitation. Center pivot system most common agriculture. As center ages, could develop leaking joint, clogged sprinklers, physical damage. This can cause areas non-uniformity that lead to under...

Urban farming, practiced by about 800 million people globally, has contributed significantly to food security and food safety. The practice has sustained livelihood of the urban and peri-urban low income dwellers in developing countries for many years. Its popularity among the urban low income is largely due to lack of formal jobs and as a means of adding up to household income. There is increa...

More attention has been paid to estimating soil nutrient status, along with a sharp decrease in total farmland acreage, especially in Beijing Municipality. However, traditional site-specific investigation makes it impossible to apply it to large scale monitoring. The objective of this study was to evaluate and classify soil nutrient status using advanced 3S (global positioning system, GPS; remo...

During 30 days male euglossine bees were bait-sampled at 12 sites, in the central Pacific coast of Colombia (ten days and four sites at each of three adjacent habitats: farmlands, highly disturbed forest and less disturbed forest) and 487 individuals were captured. Most captured individuals belonged to six species, five widely distributed through the American tropics and an endemic species. Two...
