What is conventional farming?

The prevailing agricultural system, variously called “ conventional farming ,” “modern agriculture ,” or “industrial farming,” has delivered tremendous gains in productivity and efficiency. Food production worldwide has risen in the past 50 years; the World Bank estimates that between 70 percent and 90 percent of the recent increases in food production are the result of conventional agriculture rather than greater acreage under cultivation. U.S. consumers have come to expect abundant and inexpensive food.

What is the agricultural sector?

Economically, the U.S. agricultural sector includes a history of increasingly large federal expenditures. Also observed is a widening disparity among the income of farmers and the escalating concentration of agribusiness —industries involved with manufacture, processing, and distribution of farm products—into fewer and fewer hands. Market competition is limited and farmers have little control over prices of their goods, and they continue to receive a smaller and smaller portion of consumer dollars spent on agricultural products.

What causes desertification?

Why do grasslands exist?

Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture. In Romania, however, they still exist because of the traditional (low-impact) way of farming and seasonal grazing of livestock by shepherds.

Why is fair trade important?

Fair trade chocolate and coffee from rainforests encourages sustainable management of rainforests from where these goods originate. Fair trade also helps native people retain their traditional ways of life in a way that works in harmony with local ecosystems and gives incentives to continue to protect them [4].

How does rotational grazing affect biodiversity?

Through grazing for a limited time period in one area, biodiversity of native plants increases because grasses have time to regrow equally without one species taking over and becoming invasive.

How do plants and trees help the aquifer?

Plants and trees in agricultural systems help to retain and add water to underground aquifers. This process is most effective when the crops being grown are perennials that continue to grow every year and have deep, well-established root systems.
