Telangana State Board Class 10 Social Science Chapter 11 Sustainable Development with Equity Solution:
1.) Why did the people of Jalsindhi village refuse to move out of the village?
Ans: People of Jalsindhi village were very satisfied with living in the area on the bank of the Narmada with their lands and forests. They have lived there for generations. On that land their ancestors cleared the forest, worshipped gods, improved the soil, domesticated animals and settled villages. It is that very land that they till. They have constructed their own houses where they lived. Their agriculture prospers there. That’s why, people of Jalsindhi village refused to move out of thevillage.
2.) “This is the land of our forefathers. We have a right to it. If this is lost, thenwe will only get spades and pickaxes, nothing else…” says Bava Mahaliya.Can you explain the statement?
Ans: The above lines mean that people of Jalsindhi village were very satisfied with living in the area on the bank of the Narmada with their lands and forests. They have lived there for generations. On that land their ancestors cleared the forest, worshipped gods, improved the soil, domesticated animals and settled villages. It is that very land that they till. They have constructed their own houses where they lived. Their agriculture prospers there. They earned by tilling the Earth. They tilled lands in the village and some in the forest area. On that they grew bajra, jowar, maize, boadi, bate, saunvi, kadri, chana, moth, urdi, sesame and groundnut, and many different kinds of crops.
3.) “Last, but not the least, the key to the Environmental problem lies in changinglifestyles that will minimise waste and pollution.”
- What are the various ways in which our lifestyles affect the TheEnvironment? Use examples from your own context to explain.
Ans: i) The plastic which is used a lot in these times is made up of polythene, which is a non-degredable waste. This in return harms the environment.
- ii) Smoke released from vehicles like cars, buses, motocycles, etc contains carbon monoxide with damages the air and causes air pollution.
iii) CFCs also known as Chlorofluorocarbons is released by air conditioners and refrigerators which depletes the ozone layer protecting the Earth from the sun rays.
- Find out about the various ways in which the problems of garbage andemissions are being dealt with around the world.
Ans: i) People are now using recyclable and reusable plastic bottles and bags so that it could be used again and doesn’t samage the environment.
ii) Grocery bags are now being-reused and plastic bags are now banned and replaced with paper bags.
iii) Papers used to mails, letters and other official purposes are being replaced by digital media platforms, like e-mails, to reduce the use of paper.
iv) Using the old furniture of the house to make something new.
4.) Rapid extraction of minerals and other natural resources would adverselyimpact the future development prospects. Do you agree?
Ans: i) Mining of minerals and other resources has many ill effects on the lives of the people working there as the unrefined materials gets mixed with the air they breathe, hence affecting the people working there and people living nearby. Lead and arsenic poisoning is a very common example.
ii) The unrefined sediments of these materials gets eroded to the nearby streams, ponds, lakes, hence affecting the water bodies. These sediments are also dumped by many factories and industries in their nearby ponds, streams and rivers which in result causes the harmful elements to flow through the water which causes ill-effects on the marine life and for people who uses that water.
iii) The explosions caused during mining destroys the land of the area which creates many pits, hence affecting the land and the bio-diversity of the area.
5.) Why do you think the effects of climate change may be felt by all countries?
Ans: While industrialisation has brought a lot of material comforts, at least to some, it has resulted in a world where natural resources are threatened and now even the climate is being disrupted.On issues like climate change, countries have tried to reach collective decisions. Climate change affects all countries and people, some may be more than the others. People of different countries do not even understand and cannot anticipate many of these effects. Individually, a country may take an initiative to reduce emissions of green house gases. Its The Environment would, however, continue to deteriorate if other countries do not regulate their emissions. Solutions at the global level with countries coming together has now become necessary as it has started to seriously affect the earth.
6.) Should the average temperature of the earth be treated as a natural resource for all people? Why?
Ans: No, the average temperature of the earth be treated as a natural resource for all people. During the last few decades, scientists have discovered that pollution causes the depletion of the protective ozone layer in the atmosphere which is important to absorb harmful rays of Sun. Due to pollution, the average temperature of Earth has been increasing steadily. This is causing the melting of Polar Ice Caps – the vast accumulation of water in the form of ice on the two poles. As the ice melts and joins the oceans, the water level of oceans and seas will rise causing submergence of land in the coastal areas all over the world. Countries like Bangladesh, Sri Lanka Mauritius, India and Indonesia where a very large number of people live along the sea coast will face severe problem of flooding and submergence. Even the people living deep inside the continent will not be spared as the global warming will cause erratic rainfall (unseasonal rains, excess rains and droughts) and crop failure. In other words, global climate change will affect those countries whose population particularly depends upon agriculture.
7.) What are the lessons to be drawn from the alternate PDS initiative at Zaheerabad mandal in Telangana?
Ans: In Zaheerabad mandal of Medak district of Telangana, villagers have reversed the dependence on purchased wheat and rice. It all began around the year 2000 as the women began to reflect on the loss of local food cultures. Millets were the traditional staple of the region, which had been lost to rice. Rice is nutritionally inferior compared to millets. Besides poor nutrition, people also realised that they had lost control on what grew on their land. Many fields were now fallow. Led by a voluntary organisation, Deccan Development Society, the villagers collectively decided to cultivate the fallow land and the commons. Millets were the obvious crop choice because of their suitability to the local The Environment. Millets are hardy crops and nutritious. Cultivation of dryland gave people work. Further, instead of selling the produce outside, the community started community grain bank. This operated on the principle of the PDS system (like people hold different ration cards and are assigned fixed quoatas depending on the type of ration card). Only it was locally managed, and the grain was the local grain. Instead of the grain travelling hundreds of kilometers, locally produced food was now available to ensure food security in the village.
8.) “The Environment is crucially important for the lives and livelihoods of thelocal communities and the lifestyles of local communities are harmoniouswith the The Environment.” Explain.
Ans: Many naturally existing substances like land, water, minerals and ores, products from trees and animals are central to the production process. In primary sector activities – agriculture, mining, quarrying – and in the manufacturing and energy sector, production is hugely dependent on natural resources. The other sectors of the economy too are dependent on natural resources in various degrees. The potential of The Environment to provide these resources is referred to as an The Environment’s source function. This function is depleted as resources are consumed or pollution contaminates the resources.There is another function that The Environment provides. It is to absorb and render harmless waste and pollution from various activities. Unwanted by-products of production and consumption like exhaust gases from combustion, water that isused to clean products, discarded packaging and goods that are no longer wanted are absorbed by The Environment. This is as important as the source function. The “sink function” describes an The Environment’s ability to absorb and render harmless waste and pollution. When waste output exceeds the limit of the sink function, long-term damage to The Environment occurs.
