I think it going to be better if all developing countries used agriculture as a key factor to improve the economy.
In Colombia major forms of degradation of the food is subject to poor soil protection practices disproportionately by poor livestock and large extensions of land in crops like bananas and coffee cotton etc. found that traditional crops tieneden to desaparaecer by displacement from rural to cities of many families. logging of native trees in cities and other sites attentive reserve against the purification of air sur case of Bogota, chocoana area south of the country, the illicit crops occupied a large area of fertile land and biodiversity-rich areas were completely hewn by the fumigation of glyphosate to recover these areas by the national government. And another space which plays the theme of water use case Guajira, in the mass consumption of mining cerrejon.y case elsewhere in the country. Also important is the support of the last governments of developed countries control the destruction of areas of forest areas, tropical reserve. Thanks to this important diploma we see even more damage to the environment and the effects of climate change in many species
The documentation of farmland type and use in the US is worthy of note and emulation (by other countries who wish for objective development in this aspect).
in america half of the area is use for agriculture purposes
Se denomina tierra agrícola a la porción del área de tierra cultivable, afectada a cultivo permanente y a pradera permanente. La tierra cultivable incluye aquellos terrenos definidos por la FAO como afectados a cultivos temporales (las zonas de doble cosecha se cuentan una sola vez), los prados temporales para segar o para pasto, las tierras cultivadas como huertos comerciales o domésticos, y las tierras temporalmente en barbecho.
una fracción de la tierra se usa para la agricultura, aveces las condiciones de la tierra no permiten el uso de la tierra, los pastizales y pastos contribuyen al 33% de EE UU. las tierras de cultivos representan el grueso de la comida. aunque no solo en EE UU existen tierras de cultivo y cosas así, deberían hablar a nivel mundial.
Agriculture is the back bone of our economies without land it does not exist. This involves zoning for land demarcated for agricultural potential. This involves the environmental plan.
What is spatial planning?
Less than half of the land area in the world (including the United States) is used for agriculture. The majority of agricultural lands are rangeland or pasture.
Rangelands are unsuitable for growing grain crops for a variety of reasons: the land may be too rocky or too steep, or the climate may be too cool or too dry. Livestock grazing is the major agricultural use of rangeland and pasture.
Together, rangeland and pasture comprise about 35% of non-federal land (526 million acres) in the United States. Most of the nation's rangelands are in vast areas of the western states with arid to semi-arid climates. Pastures, which are smaller managed grassy areas, are found on farms throughout the United States.
Croplands are important because they account for the bulk of food production. About 20% of the land in the United States (about 400 million acres) is croplands, with the highest concentrations in the central United States. About 70% of all cropland in the United States is classified as prime farmland. Prime farmland is land that has a growing season, a water supply from precipitation or irrigation, and sufficiently rich soil to sustain high yields when managed according to modern farming methods. Cropland may become prime farmland with the addition of the irrigation or flooding protection needed to sustain high yields.
Farmlands in the eastern and southern United States are generally smaller and produce a greater variety of crops than those in the Corn Belt and Great Plains, where a few major grain crops predominate.
In countries throughout the world, agricultural land is being lost for various reasons. Some land is being lost to other uses such as housing developments, commercial developments and roads. Unfortunately, this change in use is taking much prime agricultural land. In the United States, federal programs exist that encourage farmers to stop farming agricultural lands defined as sensitive, which pose a risk of environmental degradation.
In an attempt to help preserve prime farmland in the United States, some local and state governments and private organizations have programs to purchase easements on cropland that restricts nonagricultural use. Such croplands are temporarily or permanently retired from active production and are planted with perennial grasses or trees.
Millions of acres of agricultural land in semiarid regions are lost each year due to a phenomenon called desertification. This occurs when once-productive land becomes too arid for agricultural use because of climate change or poor land management (i.e., overgrazing of rangeland, erosion of croplands).
Years ago, the standard practice for replacing lost agricultural lands or increasing overall production in many countries was to develop new farmland from formerly uncultivated land. But now, areas of potentially arable land are shrinking in most countries. Most of the uncultivated land that does remain is marginal, with poor soils and either too little rainfall or too much.
