Human beings maintain their life by using natural resources. These sources are to be mobilized properly and rationally. Conservation of natural resources is to be done by mankind realizing the dependence on the natural resources and living beings and their interrelationship with environment.Principles of Natural Resource Conservation
Natural resources maintains a balanced environment on the earth by their natural process of regeneration. Micro-organisms, plants and animals create a favorable environment for their survival and continue their race for an infinite period of time. There are two principles of conservation of natural resources.Absolute conservation Conservation of natural resources needs to be viewed with the conservation and utilization of natural resources. Absolute conservation encompasses the quantity and quality of natural resources such as air, water, land, forest, animal, minerals, without their declination. Absolute conservation is the thinking that natural resources should be used without their utilization. Human beings including other living-beings use natural resources, which cannot be stopped. Absolute conservation is the concept that natural resources should be maintained without any disturbance in the condition in which they exist in nature.
Major objectives of absolute conservation of natural resources are:
Natural resources are essential in every step of our life. We can not imagine even a second of life in the absence of these resources. The way that we exploit these resources along with conservation is its proper utilization. Conversational use of natural resources refers to the utilization of natural resources refers to the utilization of natural resources in such a way that includes the consumption as well as conservation, with the purpose of achieving the principle of sustainability. We should clearly understand the type, status and nature of the resources. On the other hand, the renewable natural resources are available in limited amount; therefore, we should reduce their use and seek their alternatives. The concept of conversational use incorporates the following principles:
Re-use means using use the things for the next time. In re-use, the form of the resources is not changed. These are again to supply the drinks. Re-use helps conserve the natural resources in two ways. On the one hand it helps reduce the use of raw materials and on the other hand, it helps one reduce environmental pollution.
Recycling is the process of making the resources able to be used after some alteration in the structure of the resources. Re-cycling includes re-melting, recollecting and reprocessing as well. The metallic utensils and plastics are re-cycled.
Human beings depend upon the natural resources of the universe for their development activities. If they use the natural resources without their development activities. If they use the natural resources without considering their conservation, they can create a situation of imbalance in environment. Some of the important points of impact made on natural resources by human activities are explained below:
1. Scarcity of Water
Water is a renewable nature resource. water is needed for various activities of human beings, like drinking, irrigation, industry, navigation, electricity production, etc. Water scarcity leads to the degradation of vegetation which in turn increases natural disasters like soil erosion, landslides and flood.
2. Environmental pollutionThe major resources of the earth like air, water and land get polluted due to human activities. Industries are established mainly to produce valuable goods like cloths, food items, beverages, cement, bricks, etc. But, these industries are also major sources of pollution for air water and land resources and the environmental pollution is caused.
3. Depletion of wildlife
People are destroying forest for the purpose of timber, firewood and agriculture. Beside, forest is also used for the house settlement zone. The habitat of valuable animals like rhinoceros, tiger, bear, leopard, wild cow, yak, etc. is endangered.
4. DeforestationForest is not only important to get valuable forest products but also important to maintain ecological balance. Due to extreme poverty most of the people depend on forest resources for their survival. People collect firewood, timbers, folder, etc from the forest which depletes the forest resources. Landslides, floods, climatic variations such as excessive rainfall, drought, etc are also the consequences of deforestation.
5. Degradation in Eco-system
Problems like depletion of forests, floods, landslides, extreme utilization of land are started to be observed due to various activities of people. Pollution caused by industrial works degrades the status of land, water and vegetation. Natural status of the earth has started to destroy due to these reasons.
6. Depletion of pasture land
The pasture land for animals has been depleting due to various types of development activities. Overgrazing of pasture land results in the problems like soil, landslides, deforestation etc.
7. Floods, Landslides and Soil Erosion
The activities of man cause floods, landslides and soil erosion. Destruction of forest, excess use of land, cultivation of sloppy land, excess grazing, etc. have supported flood, landslides and soil erosion. Destruction of forest, excess use of land, landslides and soil erosion. It causes imbalance in the environment of hills and Terai.
8. Declining of ecosystem
A functional system operating in the environment by the interaction of living beings with their non-living environment is called ecosystem. When the resources like air, water and land get polluted then it affects the survival of plants and animals.
Human beings are the most prominent utilize and destroyer of natural resources. At the same time, he is the most thoughtful among the living beings. Therefore, it is their duty and responsibility to manage and conserve natural resources.
Forest conservation soil conservation, wildlife conservation, watershed conservation and solid waste management are the examples of natural resource conservation. Various national and international agencies have involved in such activities
1. Government agency
Different ministries of the Government of Nepal like, the ministry of forest and soil conservation, ministry of science and environment, ministry of Water resource, ministry of education and sports and the program under-taken by different agencies under it, have helped in the conservation, community forest program, reserve protected area, etc. are established under the ministry of forest and soil conservation, which also helps in the conservation of natural resources.
2. National and International AgenciesDifferent national and international agencies have been working for the conservation of natural resources. Nepal Nature Conservation Fund has conducted various programmes like environment education, sustainable development program, resource conservation etc in the Annapurna conservation area.
3. Non-government agencies
Various programmes for conservation and protection of natural resources and environment on national and local level are carried out by the non-government agencies.
4. Educational Institutions
Various aspects of natural resource conservation and environmental management have been included in the curricula of school education. Environment education is imparted through informal educational programmes.
5.Inclusion in world heritage list
Chitwan National Park and Sagarmatha National Park are including in the list of World Heritage. National Parks are making effort for protection and promotion especially.
6. Legal Provision
Various acts, directives and guidelines have been effective in the conservation and management of natural resources. The forest act 2049 B.S National Park and Wildlife Conservation Act 2029 B.S, land and Watershed conservation Act 2053 B.S., has been highly effective to control pollution and integrate environment conservation programme in development activities.
