Aresourceis any physical or virtual entity of limitedavailabilitythat needs to be consumed to obtain a benefit from it. In most cases, commercial or even non-commercial factors requireresource allocationthroughresource management.

VALUE OF A RESOURCEThe purely economic value of a resource is controlled by supply and demand. This is, however, a narrow perspective on resources as there are many things that cannot be measured in money.Natural resourceslikeforests, mountains etc. are considered beautiful so they have aesthetic value. Resources also have an ethical value as well, because it is widely recognized that it is our moral duty to protect and conserve them for the future generations

CHARACTERISTICS OF RESOURCESResources have three main characteristics:utility, quantity (often in terms ofavailability), andconsumption. However, this definition is not accepted by some, for example deep ecologists who believe that non-human elements are independent of human values.

TYPES OF RESOURCES TYPES OF RESOURCES NATURAL RESOURCES :Natural resourcesoccur naturally withinenvironmentsthat exist relatively undisturbed by mankind, in anaturalform. A naturalresourceis often characterized by amounts ofbiodiversity and geodiversityexistent in variousecosystems. Natural resources are derived from the environment. Many of them are essential for our survival while others are used for satisfying our wants.

Human resources : Human beings are also considered to be resources. The termHuman Resourcescan also be defined as the skills, energies, talents, abilities and knowledge that are used for theproduction of goods or the rendering of services.Tangible / intangible resources : Resources may be split into tangible and intangible resources. Tangible resources are those resources like equipment, vehicles which have actual physical existence; whereas intangible resources are things like corporate images, brands and patents that are present but cannot be grasped or contained.

Classification of natural resources ON THE BASIS OF ORIGIN :Biotic Biotic resources are obtained from thebiosphere, such as forests and their products, animals, birds and their products,fishand other marine organisms.Mineral fuelssuch as coal andpetroleumare also included in this category because they are formed from decayed organic matter.Abiotic Abiotic resources include non-living things. Examples include land, water,airandmineralsincludingoressuch as gold, iron, copper, silver etc.. ON THE BASIS OF THEIR STAGE OF DEVELOPMENT :Potential Resources Potential resources are those that exist in a region and may be used in the future. For example,petroleummay exist in many parts of India, having sedimentary rocks but until the time it is actually drilled out and put into use, it remains a potential resource.Actual Resources-are those that have been surveyed, their quantity and quality determined and are being used in present times. The development of an actual resource, such aswood processingdepends upon the technology available and the cost involved.Reserve Resources- The part of an actual resource which can be developed profitably in the future is called a reserve resource.Stock Resources- Stock resources are those that have been surveyed but cannot be used by organisms due to lack of technology. For example. hydrogen

ON THE BASIS OF RENEWABILITY Renewable resourcesare ones that can be replenished or reproduced easily. Some of them, like sunlight, air, wind, etc., are continuously available and their quantity is not affected by human consumption. Many renewable resources can be depleted by human use, but may also be replenished, thus maintaining a flow. Some of these, like agricultural crops, take a short time for renewal; others, like water, take a comparatively longer time, while still others, like forests, take even longer. Non-renewable resourcesare formed over very longgeological periods. Minerals and fossil fuels are included in this category. Since their rate of formation is extremely slow, they cannot be replenished once they getdepleted. Of these, the metallic minerals can be re-used by recycling them.But coal and petroleum cannot be recycled.

ON THE BASIS OF AVAILABILITYInexhaustible natural resources- Those resources which are present in unlimited quantity in nature and are not likely to be exhausted easily by human activity are inexhaustible natural resources (sunlight, air etc.)Exhaustible natural resources- The amount of these resources are limited. They can be exhausted by human activity in the long run (coal, petroleum, natural gas, etc.)

ON THE BASIS OF DISTRIBUTIONUbiquitous resources- Resources that are found everywhere are called ubiquitous resources. For exampleland,airLocalized resources- Resources that are found only at certain places are called localized resources. For exampleminerals,fossil fuels

Resource depletionis aneconomicterm referring to the exhaustion of raw materials within a region.Resourcesare commonly divided betweenrenewable resourcesandnon-renewable resources. Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. Resource depletion is most commonly used in reference to thefarming,fishing,mining, andfossil fuels.

Causes of resource depletion

Over-consumption/excessive or unnecessary use of resourcesNon-equitable distribution of resourcesOverpopulationSlash and burnagricultural practices, currently occurring in manydeveloping countriesTechnologicalandindustrialdevelopmentErosionIrrigationMiningfor oil and mineralsAquifierdepletionForestryPollutionor contamination of resources

Recycle everything you can; newspaper, cans, glass, aluminum foil and pans, motor oil, crap metal, etc. Investigate local recycling centers that take items your garbage hauler doesn't (scrap paper, plastics, appliances).Save your kitchen scraps for the compost pile. Avoid the use of household pesticides. Fly swatters work very well. Clean your windows with vinegar and water instead of chemical products. Use cold water in the washer unless it's necessary to use warm or hot.

Use washable rags, not paper towels, for cleaning spills and other household chores. Crumpled newspaper are great for washing windows. Use cloth diapers. The plastic in disposable diapers doesn't break down in landfills. Use cloth, not paper napkins. Don't put hazardous substances down your drain or in your trash (paint thinner furniture polish, etc). Dispose of them on designated hazardous-waste collection days. Don't use electrical appliances for things you can easily do by hand. Reuse brown paper bags to line your trash can instead of plastic liners. Reuse bread bags, butter tubs, etc. Use reusable containers to store foods - not plastic wraps and foil. Save your coat hangers and return them to the cleaners.Take unwanted, reusable items to a charitable organization or thrift shop. Don't leave water running needlessly.
