[34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil ...
The predominant soil in the area is grey. This type of soil is prone to erosion and being swept away by water, and cannot be used in dykes, but it is suitable for rubber plantations. The district has a climate typical of southern Vietnam, with no winter, and a distinct dry and monsoon season.
Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four). [10]: 60–61 [13] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [14] ejecting soil particles. [4]
The Mekong Delta (Vietnamese: Đồng bằng Sông Cửu Long, lit. 'Nine Dragon River Delta' or simply Đồng Bằng Sông Mê Kông, 'Mekong River Delta'), also known as the Western Region (Vietnamese: Miền Tây) or South-western region (Vietnamese: Tây Nam Bộ), is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of ...

The Vietnamese Communist Party (VCP) and Vietnamese party-state are not the only actors playing key roles as far as environmental issues are concerned. The environmental movement, part of Vietnam's civil society, consisting of grassroots organizations and non-governmental organizations (NGOs) such as the Institute of Ecological Economics, is ...
In its early stages of development, soil loss tolerance rates were inconsistent because they were obtained based on rough estimates. From 1961 to 1962, several groups of soil in the United States were designated with T rates ranging from 2 to 6 tons per acre per year. The rate was subsequently adjusted to 1 to 5 tons per acre per year. [5]
