A MACRO LEVEL OUTLOOK

Planet Earth exists since 4.5 Billion Years.

Life on Earth started since last 2 Billion Years.

Human beings (homo sapiens) came in to existence since last 2 Million years.

Civilization began since last 5000 years.

Modern Science has been there since last 750 years.

Basic Environmental Facts

1) Forest cover is just 11 per cent

against the desirable 33 per cent according to the National

Forest Policy.

Page 4: Environmental challenges of  india

2) India is one of the mega centres of biodiversity in the world.

Page 5: Environmental challenges of  india

3) About 16 rivers in the world

experience severe erosion: of

these Ganges stands 2nd and Bramaputra 3rd

Page 6: Environmental challenges of  india

5) 10 per cent of Rural & urban

population does not have access

to regular safe drinking water.

Page 7: Environmental challenges of  india

4) Population growth will lead to decline in per capita availability of

fresh water-

1947---------5150 cubic meter

2000 --------2200 cubic meter

2017 ------- 1600 cubic meter

Page 8: Environmental challenges of  india

6) 1 crore suffer due to excess arsenic in water.

Page 9: Environmental challenges of  india

7) 7 crore people in 20 states are at risk due to excess fluoride.

Page 10: Environmental challenges of  india

8) Air pollution load from transport

sector was 0.15 million tonnes in

1947, which increased to 10.3 million tonnes in 1997.

Page 11: Environmental challenges of  india

10) Pollution load from Industrial

sector was 0.2 million tonnes in

1947, 3 million tonnes in 1997.

Page 12: Environmental challenges of  india

9) The organic content of the soil at present is 0.2 per cent, while it was 3 to 3.5 per cent before green revolution.

Page 13: Environmental challenges of  india

11) At present, 1.2 billion people world wide defecate in the open and India has the uncomfortable distinction of leading the list with 665 million (2006).

Page 14: Environmental challenges of  india

12) A study conducted by the Centre for Science and Environment revealed that the GDP in India has gone up by two and a half times during 1975-95, while industrial air pollution has gone up by four times.

Page 15: Environmental challenges of  india

13) World Bank estimates the total cost

of Environmental damage in India amounts to U.S $ 9.7

billion

annually or 4.5 per cent of the GDP.

GRAIN DRAIN

Fine cereals like rice and wheat are given priority leading to over production. These crops are water intensive, less nutritious and require more inputs for cultivation.

On the other hand, coarse grains like jowar (sorghum), millets like bajra (pearl millet), ragi (finger millet), kutki (little millet), kodo (kodo millet), cheena (proso millet), kangani (foxtail millet), pseudocereals like amaranthus, buckwheat, jave (barley),jau (oats) and maize are nutritionally rich, have their own speciality like pest resistance, drought resistance and early maturity.

Page 21: Environmental challenges of  india

Projections show that India is the only country with negative growth in coarse grain production.

Page 22: Environmental challenges of  india

Public Distribution is also responsible for the sorry state of affairs.

Page 24: Environmental challenges of  india

Coarse grains contribute food for 40% of the country’s population and two-thirds of the livestock population.

Page 25: Environmental challenges of  india

Increase in diabetes, heart diseases and hypertension can be taken as the manifestation of the replacement of traditional food with food based on rice and wheat.

Page 26: Environmental challenges of  india

The poor varieties of rice and wheat grown in our country contain mostly starch and very few vitamins and minerals; they are also deficient in vitamin A and iron.

Our government is blindly inducing all people to eat these deficient food items by supplying it through PDS, as a result the problem of deficiency of micronutrients like iron, zinc, iodine and vitamins among the poor is on the increase.

Page 27: Environmental challenges of  india

M.S.Swaminathan says “ Nutritional security is in very bad shape in our country. Every third child is under weight. There are two types of hunger in our country. You can see open hunger, but hidden hunger, which is due to micronutrient deficiency, is not visible from outside. Both are serious in our country.”

Page 28: Environmental challenges of  india

The best option is to diversify part of lands under fine grain cultivation to grow coarse grains. Coarse grains make good environment and social sense, provide cheap alternatives for regional food security and adequate nutrition to the poorest of poor.

Page 29: Environmental challenges of  india

Loss of Access to Common Property Resources : (CPRs)

Resources accessible to and collectively owned/held/managed by an identifiable community and on which no individual has exclusive property rights are called Common Property Resources (NSSO, 2000).

DOMESTICALLY PROHIBITED GOODS (DPG)

Dangerous products undesired at home are called Domestically Prohibited Goods (DPG). In international parlance, DGPs are defined as products that are either banned or severely restricted for sale in the country of origin but are allowed to be exported to other countries.

Page 34: Environmental challenges of  india

Products notified as DGPs include:

Chemicals such as highly toxicliquids, benzene, chlorides, PCTsand asbestos.Pharmaceuticals for human and animal use.Fertilizers, pesticides and other plant protection products.Substances used in food and food-stuffs such as additives.Cleansing agents.Cosmetics and perfumery.Dangerous substances used in toys and car accessories.Dangerous products like auto-ignition candles, certain toy planes etc.Gunpowder, explosives and military equipment.Radioactive substances.Poisonous and deleterious substances.

Page 35: Environmental challenges of  india

Developed countries follow double standards; they allow export of DGPs to developing countries but prohibit import of the same from these countries on the ground that they may contain toxic substances

Page 36: Environmental challenges of  india

Import of Mercury

India being the largest importer of Mercury, its consumption has increased five-fold over a period of seven years, from 346 tonnes in 1997-98 to 1386 tonnes un 2002-2003.Methylmercury is neurotoxic.Exposure to it causes health hazards like irritation, speech and visual impairment, kidney failure and Alazheimer’s disease.

Page 37: Environmental challenges of  india

Many examples can be cited to point out the irrational dumping of DGPs by the industrialized nations into the poor countries. Toxic wastes, hazardous chemicals, obsolete technologies, are being donated, exported or dumped into developing countries, which are desperate to develop at any cost.

Page 38: Environmental challenges of  india

The Rich are guided by the Not-in-my-backyard (NIMBY) syndrome, while the poor by the Welcome-in-my –backyard (WIMBY) syndrome. However the poor will choose poison over starvation, because of the impact of poison is slow and less cruel.

Page 39: Environmental challenges of  india

The Basel convention

The Basel convention on the control of trans- boundary Movements of Hazardous Wastes and their Disposal was adopted in March 1989 and came into force on the 5th May 1999.

Basically these are resources both biological and genetic in forms found mostly in the tropical forests.

‘Insitu’ and ‘Exsitu’ that is in terms of bio and genetic forms in the wild, before being manipulated and developed and kept in laboratories for further genetic manipulation.

Essentially the debate boils down to the question of Economics. Only the economic benefits over the use of biodiversity cause much concern for the North and South.

Another facet of Biodiversity Convention is Sociology, quite significant from the point of actual forest dwellers who co-exist with biodiversity.

Page 48: Environmental challenges of  india

This needs to be addressed in the backdrop of globalization process, which is an inevitable mechanism in vogue. The socio-politico-economic implications of releasing such crops into the environment need to be assessed critically.

Page 49: Environmental challenges of  india

When Biodiversity Conventions was placed in the Earth Summit, for signature, almost 156 member countries had signed barring a few. Most conspicuous exception is the United States of America.

Page 50: Environmental challenges of  india

Genetically Modified (GM)

Genetically – engineered crops are those which contain a foreign gene. Geneticists today can cut out a gene from anywhere, not necessarily plant and put it into any crop.

These way traits that are not present in the particular crop can be brought in from anywhere: another plant, an animal or even a bacterium.

Genetically Modified Food Are genetically modified organisms (GMO) a panacea for solving the world’s hunger problem or a potential threat to environment in general and human health in particular? This is a tough but a formidable question for discussion.

Page 53: Environmental challenges of  india

GMOs- DisbenefitsGene escape into the environment causing growth of super weeds.

Destruction of useful insects along with the pests harmful to the crops.

Transgenic crops, which have better growth, might compete with desirable crops leading to their loss.

Unexpected and undesirable change in the ecology of that region.

Experimental errors – cloning wrong genes into the organism.

Insertion of a desired gene sequence may (cause) take place at an undesirable site in the host genome.

– Andhra Pradesh, the state where more than 500 farmers committed suicide after a failed crop in 1998.

– A packet of One kg of Bt cotton is sold at Rs.3000 per kg. This amount is excessively high when compared to the price of the conventional seed which is sold at Rs.500 per kg.

– According to GEAC rules, a refuge belt- comprising one-fifth of every field - has to be se up where planting of non- Bt varieties will be mandatory.

BAMBOO

Page 56: Environmental challenges of  india

British Rulers of India, saw bamboo as a rich exploitable resource and declared it as a tree for their own benefit, thereby preventing access to the locals.

Carl von Linne, Swedish botanist and ‘Father of Taxonomy’ classifies bamboo as a grass.

Page 57: Environmental challenges of  india

• Indian Forest Act, 1927, declared bamboo as a tree.

• Modern taxonomy classifies bamboo as a giant graminoid or grass belonging to the family Poaceae.

• If regarded as tree- major forest resource- denial of access to forest dwellers.

• If regarded as grass- minor forest resource- natives of forest have right to access.

Page 58: Environmental challenges of  india

Carl Von Linne, the father of modern taxonomy and modern ecology, argued in favour of bamboo as a giant graminoid (grass).

Page 59: Environmental challenges of  india

Forest Rights Act, 2006, FRA was passed in the Indian parliament on 13, December 2006.

This act has unfolded the prejudices against the tribal people.

Page 60: Environmental challenges of  india

Government has monopoly to harvest, use and sell bamboo.

Annual trade of bamboo in India is Rs. 10,000 to Rs. 15,000 crore.

Forms the major raw material for pulp and paper industry and construction industry.

Page 61: Environmental challenges of  india

Locals use bamboo for subsistence- part of their livelihood.

Forest departments proclaim cutting and transporting of bamboo illegal, if done by locals.

Transit passes and permission to use bamboo denied to the people who solely depend on them for existence.

Page 62: Environmental challenges of  india

India, second richest country in bamboo resources.

136 species of bamboo in India

9.57 million hectare of bamboo forest

Annual production of 4.7 million tonnes.

Forest communities have nurtured and protected bamboo for centuries.

Page 63: Environmental challenges of  india

Traditionally they use bamboo for construction of bridges, houses, fences weapons etc.

It is used as food- tender bamboo shoots serve as food.

Every day utility items like utensils, baskets, fans, mats and crafts are produced for trade.

Page 64: Environmental challenges of  india

Government should proclaim bamboo as a grass and thereby it becomes a minor forest produce and the locals would have free access.

Reluctance of State Governments to forgo the revenue creates delay in implementation of the amendment in the Forest Act.

Page 65: Environmental challenges of  india

Stakeholders partnership with easy accessibility would conserve the bamboo forest and prevent degradation.

Moreover bamboos are the most eco-friendly material that can combat global warming

Page 66: Environmental challenges of  india

Bamboos sequestrates C02 at a higher rate than any other tree.

It reduces energy use in construction.

Durable, bio-degradable and non- toxic

High resilience and earth quake proof.

Holistic green energy solution

SUSTAINABLE USAGE – only way to maintain green growth in the years to come.

Page 67: Environmental challenges of  india

Mining Industry and Environment

India has huge mineral deposits.

Mineral production in 1993-1994 was of value Rs. 25,000 crore.

In 2005-2006 it has become Rs. 84,000 crore (more than 70 per cent increase).

Mining and seismic activity

Mining leaves huge void in earth’s surface- this alters the balance of forces on rocks.

Ground collapses in mining areas and produce seismic waves.

Mining may reactivate the existing faults in earth and cause quakes.

Page 72: Environmental challenges of  india

POSCO

Pohang Iron and Steel Company, (POSCO) Korea-

US $ 12 billion POSCO project covering 1620 hectare of which 1440 hectare is forest land in the state of Odisha.

The project envisages a steel plant, power plant and port. It also requires construction of 300 kms of railway track for transport of ore from mines to factory through forest area.

Page 73: Environmental challenges of  india

Additional 2469 hectares of hilly area in Khandadhar to be brought under mining.

This major project is for economic development- according to the Odisha government.

Page 74: Environmental challenges of  india

Locals fight against the project since conception.

Are they against development?

According to Government the project will displace only 466 families, about 2,500 people who will be adequately compensated.

But the forest area is the livelihood for more than 10,000 to 15,000 people.

Page 75: Environmental challenges of  india

The forest of Sundergarh is home to Mundas, Oraons, Paudi- Bhuiyan tribes.

Their livelihood is betel cultivation in the forest land and other minor forest produce.

Forest Rights Act demands consent from these people before initiation of the project.

The State government says these people are not entitled to this right as they are not traditional forest dwelling community.

Page 76: Environmental challenges of  india

Compensation of Rs. 28.75 lakhs per hectare of acquired land is being offered.

Betel farming provides Rs. 10- 17.5 lakhs per hectare per year.

The compensation will be equal to 2-3 years of revenue.

POSCO cannot employ locals as they are not skilled labors.

Page 77: Environmental challenges of  india

POSCO may be development but will be development that takes the livelihood of the people for whom the project is meant for.

It is a tussle between land based economic growth as against industrial growth.

POSCO is about GROWTH versus GROWTH.
