Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...
Weaknesses of ex situ conservation include: 1) it is costly to maintain seeds and germplasm healthily in perpetual storage, or in field collections; 2) Coverage of the diversity of neglected and underutilized crops or crop wild relatives is currently very limited. Genebanks have largely focused on the conservation of major staple crops while ...
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. [1] Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least ...
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans , but sometimes to other living organisms too. It is a key geographical term.
A 2020 U.S. survey found that typical indoor agriculture crops, per pound of crop yield, consumed between US$0.47 (for leafy greens) and US$1.38 (for microgreens) in inputs (especially seed, growing media, and nutrients) -- though tomatoes were reported at US$0.06 inputs per pound. Labor costs for container farms were reported at US$2.35 per pound.
Horticulture and agriculture as types of subsistence developed among humans somewhere between 10,000 and 8,000 years ago in the Fertile Crescent region of the Middle East. [1] The reasons for the development of agriculture are debated but may have included climate change , and the accumulation of food surplus for competitive gift-giving . [ 2 ]
Worldwide employment In agriculture, forestry and fishing in 2021. India has one of the highest number of people employed in these sectors. As per the 2014 FAO world agriculture statistics India is the world's largest producer of many fresh fruits like banana, mango, guava, papaya, lemon and vegetables like chickpea, okra and milk, major spices like chili pepper, ginger, fibrous crops such as ...
The physiological density or real population density is the number of people per unit area of arable land. A higher physiological density suggests that the available agricultural land is being used by more and may reach its output limit sooner than a country that has a lower physiological density.
