The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater. Pollutants from farming include sediments, nutrients, pathogens, pesticides, metals, and salts. [1] Animal agriculture has an outsized impact on pollutants that enter the environment.
Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transport emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog, and climate change. [6]
The act attempted to correct earlier government policy that encouraged farmers to use their land without concern to the repercussions. The result of these agricultural methods (mostly the way farmers plowed their land) made it vulnerable to the winds. The dry ground, now exposed, rose up to create the "black storms".
The principal environmental issues associated with runoff are the impacts to surface water, groundwater and soil through transport of water pollutants to these systems. Ultimately these consequences translate into human health risk, ecosystem disturbance and aesthetic impact to water resources.
Land-use change is fundamental to the operations of the biosphere because alterations in the relative proportions of land dedicated to urbanisation, agriculture, forest, woodland, grassland and pasture have a marked effect on the global water, carbon and nitrogen biogeochemical cycles and this can negatively impact both natural and human ...
[2]: 2914 The way humans use land, and how land use is changing, has many impacts on the environment. [3] [4] Effects of land use choices and changes by humans include for example urban sprawl, soil erosion, soil degradation, land degradation and desertification. [5] Land use and land management practices have a major impact on natural ...
Leaching is an important transport pathway for P losses from agricultural fields in predominantly flat areas with sandy soils or soils prone to preferential flow. [7] As opposed to nitrogen phosphorus does interact with soil particles via adsorption and desorption .
