The Philippines is one of many countries in which ecological marginalization has occurred. High rates of population growth — over 2 percent per year — have made cropland relatively scarce in the fertile lowlands, forcing many farmers to move into the less productive uplands. This migration was also encouraged by the fact that the land ownership in the lowlands was concentrated in the hands of a few elite landholders.

As the lowland-to-upland migration proceeded, rising cultivation in the ecologically fragile uplands has led to erosion and ecological degradation, further shrinking the supply of available cropland. These various forms of environmental scarcity can lead to a number of potentially destabilizing social effects, specifically:.

Rapid population growth, environmental degradation, and inefficient practices led to increasing scarcity of both cropland and water by the early s. As a result, while agricultural production and the national economy continued to grow, the benefits of this growth were not enjoyed equitably and income inequality has increased. Impoverished rural residents have flooded into cities looking for work, along with refugees from Afghanistan and returning workers from overseas.

The influx of migrants overwhelmed municipal services in cities like Karachi, where population growth rates exceeded six percent in the mids. Disruptive social effects such as these, in turn, can lead to violence under certain conditions. If group tensions in society are high, migration and relative deprivation can be a particularly volatile mix. In Pakistan, ethnic conflict became a serious urban problem as the influx of migrants altered the ethnic balance in the cities.

The result has been long-running but diffuse urban violence that has simmered since the mids. The murder rate in Karachi, for example, more than doubled between and , and attacks on municipal offices — particularly the electricity and water utilities — became common. In sum, the connection between environmental scarcity and civil violence is indirect but important. Environmental scarcity is never the sole cause of conflict, but it is often an aggravating or contributing factor. Future efforts at conflict prevention and resolution should take the role that environmental scarcity plays into account, and appropriate interventions to prevent demand-, supply-, and structurally-induced scarcity should be pursued.

This is because of the limited availability of substances in nature. Water is a renewable natural resource and vital for all life. There is no substitute for water. Man uses water not only for drinking but also for a number of other activities like bathing, cooking, washing, irrigation, power generation and also as a means of transportation. Our water requirement is fulfilled entirely by nature. We get water through rainfall and from oceans, rivers, canals and wells.

Whenever the water-cycle in nature is disrupted, the ecological-balance in nature is disturbed. Water is often wasted during its use. The rivers and canals near the big cities get polluted due to industrial wastes or sewage which is thrown into them. Indiscriminate felling of plants by man to satisfy his greed has also upset the water-cycle in nature. This has resulted in water shortage. Water is renewable only if it is protected against wastage, pollution and if a thick cover of forest plants is maintained.

Soil is also a renewable natural resource. Man depends on agriculture for food, clothing, medicine and many other necessities. Land is also being used for industrialization and urbanization. We know that the surface of the earth is limited and so is its soil. Random and excessive cutting down of trees, quarrying for minerals and ores followed by heavy rains leads to washing away of the rich top soil necessary for plants.

It may even lead to landslides causing great damage to man. Growing crop after crop of the same type without replenishing the nutrients that are used-up results in the land becoming useless for cultivation after a few years. If plants do not grow on the land, soil tends to be washed away by rain or wind causing soil erosion.

It is clear that land is good for agricultural purposes when it is fertile and land is fertile when it is covered with or surrounded by trees. For agricultural purposes, man has altered the texture and fertility of large tracts of fertile land and made the land unfit for cultivation and finally converted them into desert areas.

The Thar Desert, for example, is entirely a man-made desert. At one time it was so thick with forest that Emperor Akbar went hunting there. Soil is a renewable resource only if it is protected from erosion and if suitable amount of organic matter is added to it from time to time. Barren soil cannot renew itself as it remains exposed to natural forces which cause erosion. Forests are one of the most useful renewable resources.

They are our national wealth. They provide the best habitat for various kinds of wild animals. Forests are a must for the survival of animals. They purify air, control pollution to some extent, regulate the climate, control floods, prevent soil erosion and maintain soil fertility.

We also get numerous useful products like wood, rubber, gum, resin, honey, bee wax, medicinal plants, bamboo, lac, timber etc. One of the most important uses of forest is that it helps in maintaining the ecological-balance of a place. Deforestation, over-grazing, forest fires, and several pests and diseases have destroyed our forests. Forests are renewable resource only if man takes care to replant the trees which he cuts down.

Deforestation and indiscriminate hunting has led to a depletion of wildlife. Wildlife includes all plants and animals that are not domesticated, but in strict sense, they are the undomesticated animals specially mammals, reptiles, birds and fishes which are generally hunted. Wildlife is very important. Killing of one species may cause considerable disturbance in the food-chain and food-web and thus may upset other species.

In the long term, these changes may also affect man. Snakes, for example, are feared by most and are therefore killed indiscriminately. All snakes are, however, not poisonous. They play a key role in the balance of nature by acting as predators of rats and mice. Killing a large number of snakes leads to an increase in the population of rats and mice. Rats, in turn, damage crops and eat-up stored grain. Ultimately, this affects man. Due to over-exploitation of forests, many plants and animals have become extinct.

The Cheetah, the Sikkim stag, the Mountain quail, the Pink headed duck etc. Some species of cranes, bustards, partridges, pigeons, doves, hornbills, Kashmir stag, swamp-deer etc. Wildlife is renewable only if indiscriminate hunting and deforestation is prevented. Hence, it is clear from the above that most of the renewable resources are exhaustible and care needs to be taken about their utilization. Non-renewable resources are those which are not replaced in the environment after their utilization.

Metals, coal, natural gas, minerals etc. Man has to be very careful in using these resources so that he may obtain the maximum benefit from them. This is because these resources are limited in quantity and are not renewable. The demand for natural resources is increasing as the human population is increasing at a tremendous rate.

More and more cities and towns are coming up for providing shelter and other basic necessities for the ever increasing population. This has resulted in the depletion of some resources. Several new industries are being established in rural as well as urban areas to generate employment and to produce consumer articles for daily use. This has resulted in over-exploitation of our natural resources.

Deforestation means large scale cutting down of forests. The depletion of forests has also reduced the other renewable resources like soil, water and wildlife. Unscientific mining and quarrying for the extraction of minerals and ores have also depleted resources. Repeated growing of the same crop year-after-year and excessive use of fertilizers and pesticides reduces soil productivity and makes the soil sick.

This paper will discuss scarcity of potentially disconcerting resource areas i. As far as field of energy is concerned, the expectation from market-stimulated solutions are high, latest processes of conservation and production of alternative fuels may prove to be effective.

The following threatening area of shortage, is strategic minerals which is of crucial importance for the stability of economy. Then comes the scarcity of food availability, which appears as the utmost long-term year intimidation to the nations for its impacts on world stability. Inoue and Isozaki, If current trends of scarcity of natural resources persist any longer, undoubtedly the upcoming years can be anticipated to be more polluted, more crowded, economically less stable and more at risk to create disturbance in the planet where we live at present.

Depletion of natural resources represents lack of efforts made by the governments to preserve them. This conditions will prove to be extremely hazardous if governments take no actions in terms of institutions, public policies or rates of technological advancement. In the start of twentieth century none of the countries within European continent had total economic independence.
