7 ENVIRONMENT AND SUSTAINABLE DEVELOPMENT After studying this chapter, the learners will understand the concept of environment analyse the causes and effects of ‘environmental degradation’ and ‘resource depletion’ understand the nature of environmental challenges facing India relate environmental issues to the larger context of sustainable development. ENVIRONMENT AND SUSTAINABLE DEVELOPMENT 115 2024-25 The environment, left to itself, can continue to support life for millions of years. The single most unstable and potentially disruptive element in the scheme is the human species. Human beings, with modern technology, have the capacity to bring about, intentionally or unintentionally, far-reaching and irreversible changes in the enviornment. Anonymous 7.1 INTRODUCTION and abiotic factors that influence each other. While all living elements — the In the earlier chapters we have birds, animals and plants, forests, discussed the main economic issues fisheries etc. — are biotic elements, faced by the Indian economy. The abiotic elements include air, water, land economic development that we have etc. Rocks and sunlight are examples achieved so far has come at a very heavy of abiotic elements of the environment. price — at the cost of environmental A study of the environment then calls quality. As we step into an era of for a study of the inter-relationship globalisation that promises higher between these biotic and abiotic economic growth, we have to bear in components of the environment. mind the adverse consequences of the past developmental path on our Functions of the Environment: The environment and consciously choose a environment performs four vital path of sustainable development.

The rising population of the developing countries and the affluent consumption and production standards of the developed world have placed a huge stress on the environment in terms of its first two functions. Many resources have become extinct and the wastes generated are beyond the absorptive capacity of the environment.

Air Pollution Water Pollution Noise Pollution Asthma Cholera ENVIRONMENT AND SUSTAINABLE DEVELOPMENT 117 2024-25 Box 7.1: Global Warming Global warming is a gradual increase in the average temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. Much of the recent observed and projected global warming is human-induced. It is caused by man-made increases in carbon dioxide and other greenhouse gases through the burning of fossil fuels and deforestation. Adding carbon dioxide, methane and such other gases (that have the potential to absorb heat) to the atmosphere with no other changes will make our planet’s surface warmer. The atmospheric concentrations of carbon dioxide and CH4 have increased by 31 per cent and 149 per cent respectively above pre-industrial levels since 1750. During the past century, the atmospheric temperature has risen by 1.1°F (0.6°C) and sea level has risen several inches. Some of the longer-term results of global warming are melting of polar ice with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases. Among factors that may be contributing to global warming are the burning of coal and petroleum products (sources of carbon dioxide, methane, nitrous oxide, ozone); deforestation, which increases the amount of carbon dioxide in the atmosphere; methane gas released in animal waste; and increased cattle production, which contributes to deforestation, methane production, and use of fossil fuels. A UN Conference on Climate Change, held in Kyoto, Japan, in 1997, resulted in an international agreement to fight global warming which called for reductions in emissions of greenhouse gases by industrialised nations.

Added to these are the health costs of The biggest question that arises is: degraded environmental quality — are environmental problems new to this decline in air and water quality (seventy century? If so, why? The answer to this per cent of water in India is polluted) question requires some elaboration. In have resulted in increased incidence of the early days when civilisation just respiratory and water-borne diseases. began, or before this phenomenal Hence the expenditure on health is also increase in population, and before rising. To make matters worse, global countries took to industrialisation, the environmental issues such as global demand for environmental resources warming and ozone depletion also and services was much less than their contribute to increased financial supply. This meant that pollution was commitments for the government. within the absorptive capacity of the 118 INDIAN ECONOMIC DEVELOPMENT 2024-25 Box 7.2: Ozone Depletion Ozone depletion refers to the phenomenon of reductions in the amount of ozone in the stratosphere. The problem of ozone depletion is caused by high levels of chlorine and bromine compounds in the stratosphere. The origins of these compounds are chlorofluorocarbons (CFC), used as cooling substances in air- conditioners and refrigerators, or as aerosol propellants, and bromofluorocarbons (halons), used in fire extinguishers. As a result of depletion of the ozone layer, more ultraviolet (UV) radiation comes to Earth and causes damage to living organisms. UV radiation seems responsible for skin cancer in humans; it also lowers production of phytoplankton and thus affects other aquatic organisms. It can also influence the growth of terrestrial plants. A reduction of approximately 5 per cent in the ozone layer was detected from 1979 to 1990. Since the ozone layer prevents most harmful wavelengths of ultraviolet light from passing through the Earth’s atmosphere, observed and projected decreases in ozone have generated worldwide concern. This led to the adoption of the Montreal Protocol banning the use of chlorofluorocarbon (CFC) compounds, as well as other ozone depleting chemicals such as carbon tetrachloride, trichloroethane (also known as methyl chloroform), and bromine compounds known as halons.

Hence to meet the growing needs of the environmental problems did not arise. expanding population, things changed. The result was that the demand for resources for both production and consumption went beyond the rate of regeneration of the resources; the pressure on the absorptive capacity of the environment increased tremendously — this trend continues even today. Thus what has happened is a reversal of supply-demand relationship for environmental quality — we are now faced with increased Fig. 7.2 Damodar Valley is one of India’s most demand for environmental industrialised regions.

Hence the environmental issues of waste generation and pollution have become critical today. 7.3 STATE OF INDIA’S ENVIRONMENT India has abundant natural resources in terms of rich quality of soil, hundreds of rivers and tributaries, Fig. 7.3 Deforestation leads to land degradation, biodiversity loss and lush green forests, air pollution plenty of mineral deposits beneath the land surface, vast pressure on its finite natural stretch of the Indian Ocean, ranges of resources, besides creating impacts on mountains, etc. The black soil of the human health and well-being.

However, the developmental unstable use and inappropriate activities in India have resulted in management practices. 120 INDIAN ECONOMIC DEVELOPMENT 2024-25 Box. 7.3: Chipko or Appiko — What’s in a Name? You may be aware of the Chipko Movement, which aimed at protecting forests in the Himalayas. In Karnataka, a similar movement took a different name, ‘Appiko’, which means to hug. On 8 September 1983, when the felling of trees was started in Salkani forest in Sirsi district, 160 men, women and children hugged the trees and forced the woodcutters to leave. They kept vigil in the forest over the next six weeks. Only after the forest officials assured the volunteers that the trees will be cut scientifically and in accordance with the working plan of the district, did they leave the trees. When commercial felling by contractors damaged a large number of natural forests, the idea of hugging the trees gave the people hope and confidence that they can protect the forests. On that particular incident, with the felling discontinued, the people saved 12,000 trees. Within months, this movement spread to many adjoining districts. Indiscriminate felling of trees for fuelwood and for industrial use has led to many environmental problems. Twelve years after setting up of a paper mill in Uttar Kanara area, bamboo has been wiped out from that area. “Broad-leaved trees which protected the soil from the direct onslaught of rain have been removed, the soil washed away, and bare laterite soil left behind. Now nothing grows but a weed”, says a farmer. Farmers also complain that rivers and rivulets dry up quicker, and that rainfall is becoming erratic. Diseases and insects earlier unknown are now attacking the crops. Appiko volunteers want the contractors and forest officials to follow certain rules and restrictions. For instance, local people should be consulted when trees are marked for felling and trees within 100 metres of a water source and on a slope of 30 degrees or above should not be felled. Do you know that the government allocates forestlands to industries to use forest materials as industrial raw material? Even if a paper mill employs 10,000 workers and a plywood factory employs 800 people but if they deprive the daily needs of a million people, is it acceptable? What do you think?

This was followed by states establishing their own state level boards to address all the environmental concerns. They investigate, collect and disseminate information relating to water, air and land pollution, lay down standards for sewage/trade effluent and emissions. These boards provide technical assistance to governments in promoting cleanliness of streams and wells by prevention, control and abatement of water pollution, and improve the quality of air and to prevent, control or abate air pollution in the country. These boards also carry out and sponsor investigation and research relating to problems of water and air pollution and for their prevention, control or abatement. They organise, through mass media, a comprehensive mass awareness programme for the same. The PCBs prepare manuals, codes and guidelines relating to treatment and disposal of sewage and trade effluents. They assess the air quality through regulation of industries. In fact, state boards, through their district level officials, periodically inspect every industry under their jurisdiction to assess the adequacy of treatment measures provided to treat the effluent and gaseous emissions. It also provides background air quality data needed for industrial siting and town planning. The pollution control boards collect, collate and disseminate technical and statistical data relating to water pollution. They monitor the quality of water in 125 rivers (including the tributaries), wells, lakes, creeks, ponds, tanks, drains and canals. Ø Visit a nearby factory/irrigation department and collect the details of measures that they adopt to control water and air pollution. Ø You might be seeing advertisements in newspapers, radio and television or billboards in your locality on awareness programmes relating to water and air pollution. Collect a few news-clippings, pamphlets and other information and discuss them in the classroom. In India, air pollution is widespread vehicles (two-wheeled vehicles and cars in urban areas where vehicles are the only) constituted about 85 per cent of major contributors and in a few other the total number of registered vehicles areas which have a high concentration thus contributing significantly to total of industries and thermal power plants. air pollution load.

The concept of sustainable development Work This Out was emphasised by the United Nations Conference on Environment and Ø You can see a column on the Development (UNCED), which defined measure of air pollution in it as: ‘Development that meets the need any national daily.

The The above points highlight the use of the concept ‘needs’ in the challenges to India’s environment. The definition is linked to distribution of various measures adopted by the resources. The seminal report — Our Ministry of Environment and the Common Future — that gave the above central and state pollution control definition explained sustainable boards may not yield reward unless development as ‘meeting the basic we consciously adopt a path of needs of all and extending to all the sustainable development. The concern opportunity to satisfy their aspirations for future generations alone can make for a better life’. Meeting the needs of development last forever.

Ø Population explosion, affluent consumption and production have placed a huge stress on the environment. Ø Developmental activities in India have put immense pressure on its finite natural resources, besides creating impact on human health and well-being. Ø The threat to India’s environment is of two dimensions — threat of poverty induced environmental degradation and the threat of pollution from affluence and a rapidly growing industrial sector. Ø Though the government, through various measures, attempts to safeguard the environment, it is also necessary to adopt a path of sustainable development. Ø Sustainable development is development that meets the need of the present generation without compromising the ability of the future generation to meet their own needs. Ø Promotion of natural resources, conservation, preserving regenerative capacity of ecological system and avoiding the imposition of environmental risks on future generations would lead to sustainable development.
