Environmental impact of Agriculture is the effect that different farming practices have on the ecosystems around them. The environmental impact of Agriculture varies based on wide variety. It also depend on other climatic changes such as rainfall and temperature. The environmental impact depends on production practices of system used by farmers
There are two types of indicators of environmental impact: “means-based”, which is based on the farmer’s production methods, and “effect-based”, which is the impact that farming methods have on the farming system or on emissions to the environment. Some of the environmental issues that are related to agriculture are climate change, deforestation, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Climatic changes and Agriculture are interrelated process, Global warming is projected impacts like temperature, precipitation,glacial runoff. Rising carbondioxide effects both detrimental, beneficial on crop yields. The radioactive forcing, Land use, deforestation, desertification change global warming which is reduce rains.
- Deforestation causes loss of habit for millions of species. It isalso known as climatic changer. It reduces water cycle,which water vapour back to the environment. The removal of trees also causes extreme fluctuations on temperature
- Irrigation can led to number of problems. If we over irrigated,it leads to water pollution ,soil degradation,chemical pollution and salinity increases.
- Pollutants like fertilizers,pesticides,herbicides can control pests but degrade soil nutrients and fertility. It residue in foods,air pollutants spray,bio remedies.
- Wastes like Agricultural,animals,plastic reduces soil nature.
By using organic materials and primitive farming we can reduce environmental impacts on farming.Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. If we resolve we can sustain more farming.
