Agricultural productivity is becoming increasingly important as the world population continues to grow. [14] As agricultural productivity grows, food prices decrease, allowing people to spend less on food, and combatting hunger. [15] India, one of the world's most populous countries, has taken steps in the past decades to increase its land ...
A farmer can invest a large amount of money to increase his yields by a few percent, for example with an extremely expensive fertilizer, but if that cost is so high that it does not produce a comparative return on investment, his profits decline, and the higher yield can mean a lower agricultural productivity in this case. A yield is a 'partial ...
Increased erosion in agricultural landscapes from anthropogenic factors can occur with losses of up to 22% of soil carbon in 50 years. [99] Climate change will also cause soils to warm. In turn, this could cause the soil microbe population size to dramatically increase 40–150%. Warmer conditions would favour growth of certain bacteria species ...
Climate change will exacerbate current biotic stresses on agricultural plants and animals. [6] Increases of atmospheric carbon dioxide (CO 2), rising temperatures, and altered precipitation patterns will affect agricultural productivity. Increases in temperature coupled with more variable precipitation will reduce productivity of crops, and ...
A study for the U.S. Office of Technology Assessment concluded that regarding industrial agriculture, there is a "negative relationship between the trend toward increasing farm size and the social conditions in rural communities" on a "statistical level". [67] Agricultural monoculture can entail social and economic risks. [68]
Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries.. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself [1] [2]), with an ...
Tilth is a physical condition of soil, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, soil biota, rate of water infiltration and drainage.
The impact of agricultural policy on reducing poverty differs across countries and is influenced by a variety of factors, such as the level of government policy support, the degree of public and private investment in agriculture, the different types of agriculture, and the growth rates of agriculture parallel to non-agriculture sectors.
