Write a short note on land resources ?
Answers
Answer:
Land resources mean the resources available from the land, thus the agricultural land which contain natural fertilizer for growth of the products sown; the underground water, the various minerals like coal, bauxite, gold and other raw materials.
The more a country is able to locate and use the raw materials, the more the industrialization of that country, area etc.
Land resource refers to the land available for exploitation, like non agricultural lands for buildings, developing townships etc
Land resources (natural resources) (economically referred to as land or raw materials) occur naturally within environments that exist relatively undisturbed by mankind, in a natural form.
A natural resource is often characterized by amounts of biodiversity existent in various ecosystems.
Natural resources are derived from the environment. Many of them are essential for our survival while others are used for satisfying our wants.
Natural resources may be further classified in different ways.
Underground geological resources (oil, gas, ores, precious metals), and
Deeper geohydrological resources that normally bear no relation to the surface topography such as confined aquifers, are excluded from the group of components of the natural land unit, although it is recognized that some countries consider them as part of individual land ownership (and hence with rights to exploit or sell them).
Land as a resource
Natural resources, in the context of “land” as defined above, are taken to be those components of land units that are of direct economic use for human population groups living in the area, or expected to move into the area: near-surface climatic conditions; soil and terrain conditions; freshwater conditions; and vegetational and animal conditions in so far as they provide produce. To a large degree, these resources can be quantified in economic terms. This can be done irrespective of their location (intrinsic value) or in relation to their proximity to human settlements (situational value).
Environmental resources are taken to be those components of the land that have an intrinsic value of their own, or are of value for the longer-term sustainability of the use of the land by human populations, either in loco or regional and global. They include biodiversity of plant and animal populations; scenic, educational or research value of landscapes; protective value of vegetation in relation to soil and water resources either in loco or downstream; the functions of the vegetation as a regulator of the local and regional climate and of the composition of the atmosphere; water and soil conditions as regulators of nutrient cycles (C, N. P. K, S), as influencing human health and as a long-term buffer against extreme weather events; occurrence of vectors of human or animal diseases (mosquitoes, tsetse flies, blackflies, etc.).
Environmental resources are to a large degree “non-tangible” in strictly economic terms
Land is a major resource for agricultural development worldwide.
The components of the natural land unit can be termed land resources, including physical, bionic, environmental, infrastructural, social and economic components, in as much as they are fixed to the land unit.
Land, a critically important national resource, supports all living organisms including plants as well as every primary production system such as roads, industries, communication and storage for surface and ground water, among others.
hope it helps dear...
The most important natural resource upon which all human activity is based is land. It is used for growing crops , building houses ,constructing road and railway tracks ,establishing Industries glazing animal , mining , etc . In short, almost all human activities related to food ,shelter and clothing take place on land. Lithosphere consists of loose surface material called soil it is a combination of organic and inorganic matter. The organic component which consists of dead and decomposed parts of animal and plant is known as humus. The inorganic component is formed by Rock particles and Minerals, such as lime, iron, ect. Soil is formed as a result of the long, continued weathering process of Rocks. It also contains water and air which occupy its pore spaces. About 90% of the world's population is inhabited In the plain areas of the alluvial soil of the Tropical and sub - tropical areas. These are the areas of intensive crop cultivation with high yields. All these areas support dense population. In contrast , sparse population is seen in areas of high altitude, deserts and equatorial forest region Where slopes are step temperature is either too hot to cold soils are thin and infertile . These areas are inhabited by people who are engaged in hunting , gathering ,fishing and shifting agriculture . It is very important for us to take initiative to conserve forest by discouraging deforestation and encouraging afforestation . The availability of land on earth is limited there is a conflict over the access and rights of natural resources it has also resulted in tough competition between the agriculture and other sectors over uses of land . Movever , land also suffers from various problems such as soil erosion, degradation and deforestation.
