The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
Agriculture contributes greatly to soil erosion and sediment deposition through intensive management or inefficient land cover. [32] It is estimated that agricultural land degradation is leading to an irreversible decline in fertility on about 6 million ha of fertile land each year. [ 33 ]
Livestock's Long Shadow: Environmental Issues and Options is a United Nations report, released by the Food and Agriculture Organization (FAO) of the United Nations on 29 November 2006, [1] that "aims to assess the full impact of the livestock sector on environmental problems, along with potential technical and policy approaches to mitigation".

Mily Trevino-Sauceda was 9 when her mother fell as she worked to move irrigation pipes along rows of potato and alfalfa on an Idaho farm. Decades later, the memory remains sharp for Trevino ...
Ecological farming is a concept that focused on the environmental aspects of sustainable agriculture. Ecological farming includes all methods, including organic, which regenerate ecosystem services like: prevention of soil erosion, water infiltration and retention, carbon sequestration in the form of humus, and increased biodiversity.

Soil-conservation farming involves no-till farming, "green manures" and other soil-enhancing practices which make it hard for the soils to be equalized. Such farming methods attempt to mimic the biology of barren lands. They can revive damaged soil, minimize erosion, encourage plant growth, eliminate the use of nitrogen fertilizer or fungicide ...
Meat is obtained through a variety of methods, including organic farming, free-range farming, intensive livestock production, and subsistence agriculture. The livestock sector also includes wool, egg and dairy production, the livestock used for tillage, and fish farming. Animal agriculture is a significant contributor to greenhouse gas emissions.
Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers. For example, deforestation reduces the quantity of plants that may anchor soil and protect it from erosion, whereas overgrazing depletes vegetation and ...
