The agricultural policy of the United States is composed primarily of the periodically renewed federal U.S. farm bills.The Farm Bills have a rich history which initially sought to provide income and price support to US farmers and prevent them from adverse global as well as local supply and demand shocks.
Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. 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]
Native American farming practices are specific to local environments and work with natural processes. [157] This is a practice called Permaculture, and it involves a deep understanding of the local environment. [158] Native American farming techniques also incorporate local biodiversity into many of their practices, which helps the land remain ...
Small farms tend to be more sustainable than large farming operations, because of differences in their management and methods. [35] Industrial agriculture replaces human labor using increased usage of fossil fuels, fertilizers, pesticides, and machinery and is heavily reliant on monoculture . [ 36 ]
In the U.S. over the past 25 years, urban farming has become crucial in helping alleviate a phenomenon known as food deserts, where grocery chains began pulling out of inner cities and residents ...
Climate change and agriculture are complexly related processes. In the United States , agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. [ 1 ] Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion ...
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
Theory suggests that organic farming practices, which exclude the use of most synthetic pesticides and fertilizers, may be beneficial for biodiversity. This is generally shown to be true for soils scaled to the area of cultivated land, where species abundance is, on average, 30% richer than that of conventional farms. However, for crop yield ...
