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 ...
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 ...
Agrifood systems emissions in 2021. To feed a world population forecast to reach 9.7 billion in 2050, [18] FAO estimates that agriculture may need to produce 40–54 percent more food, feed and biofuel feedstock than in 2012, depending on the scenario. [19]
The geography of food is a field of human geography.It focuses on patterns of food production and consumption on the local to global scale. Tracing these complex patterns helps geographers understand the unequal relationships between developed and developing countries in relation to the innovation, production, transportation, retail and consumption of food.
An increase in the use of technology for farming has transformed the small local farm of the 1940s in to large production facilities. [8] [11] Several federal agencies, such as the US Department of Agriculture and the Food and Drug Administration, manage and sustain the productivity of the US food distribution system. [8]
Sustainable intensification encompasses specific agriculture methods that increase production and at the same time help improve environmental outcomes. The desired outcomes of the farm are achieved without the need for more land cultivation or destruction of natural habitat; the system performance is upgraded with no net environmental cost.
[1] [3] USDA research indicates that these climatic changes will lead to a decline in yield and nutrient density in key crops, as well as decreased livestock productivity. [4] [5] Climate change poses unprecedented challenges to U.S. agriculture due to the sensitivity of agricultural productivity and costs to changing climate conditions. [6]
