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 ...
Population density is the number of people per unit of area, usually transcribed as "per square kilometre" or square mile, and which may include or exclude, for example, areas of water or glaciers. Commonly this is calculated for a county , city , country , another territory or the entire world .
An area with a population density of up to 400 per square kilometer, Villages with clear surveyed boundaries but no municipal board, A minimum of 75% of male working population involved in agriculture and allied activities. [11] RBI defines rural areas as those areas with a population of less than 49,000 (tier -3 to tier-6 cities). [11]
For example, deforestation (the systematic and permanent conversion of previously forested land for other uses) has historically been a primary facilitator of land use and land cover change. [10] [11] The study of land change relies on the synthesis of a wide range of data and a diverse range of data collection methods. [12]
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...
In agriculture, farmers avoid these very high densities as they do not contribute to seed yield. Normal densities in modern agriculture depend on final plant size and vary between 5-10 plants per square meter for Maize till 200-300 plants per square meter for Rice or Barley. In forestry, normal densities are less than 0.1 plants per square meter.
A second supporting service is to maintain the habitat of wild biodiversity, particularly associated biodiversity, for example pollinators and predators. Agrobiodiversity can support wild biodiversity through the use of field margins, riparian corridors, hedgerows and clumps of trees, which provide and connect habitats.
73% of utilised agricultural area is arable land. [9] This percentage is among the highest in Eastern Europe. [6] Moldova's land area can be separated into three differing agro-ecological zones, where terrain, soil type, climate and water availability vary between the Northern, Central and Southern agro-ecological zones.
