Degree Programs in Environment

Thursday, July 9th, 2009

Soon after my K2K journey last year, I decided to pursue research in the area of environment and natural resources. Here is a list I have compiled of some of the degrees in the domains I am interested in. Considering time and money, I may apply to five different programs.

If you need additional information, please visit the websites. Note that this compilation is based purely on my preferences. BTW, education in Sweden is free till 2010. If you apply this year to any of the universities in Sweden, you just have to manage your living expenses. From 2011 onwards, Sweden would be charging tuition fee to foreign students.

If you know / come across any interesting quality programs in environment sciences / management, please let me know.

Are all cyclists environment friendly?

Friday, July 3rd, 2009

I would say – No, not at all.

Cycling has different connotations.

  1. Poor people who cannot afford other means of transport.
  2. People who have adopted cycling by choice.
  3. People who have adopted cycling for fun.

Let us consider the first group. If a person is poor, he is struggling to meet his needs. His overall carbon foot print will be minimal. So he is the most eco-friendly person among the lot. (India’s carbon emission, in relation to its population, is very minimal because 70% of the population is poor enough to have minimal carbon footprint)

The second lot, the most complex of the lot, tend to be self righteous, sometimes. Cyclists tend to be a bit arrogant to the rest of the population. They act as though they are putting all the effort to save the planet while the rest are basking in the luxury of automobiles. Cycling can be one of the ways to minimize carbon footprint. I don’t know how many of those cyclists are firing unnecessary printouts or keeping their computers on at office, always. I don’t know how many of them take prolonged showers, keep tap water running while brushing teeth or shaving. I don’t know how many of them compost their kitchen wastes, refrain from burning crackers during diwali or harvest rainwater during monsoons. I don’t know how many of them have reduced their meat consumption or eating organic or non-exotic food items. I don’t know how many of them are really bothered about unnecessary consumerism and have cut down on shopping. I don’t know how many of them reject plastic bags and carry their own cloth bags.

I have seen people who don’t cycle but have adopted many other ways of being eco-friendly. So we need not be arrogant to non-cyclists.

Cycling, as a sport, is very resource intensive. Also, these cyclists may be squandering environment in their normal way of living but might have adopted cycling as a fun sport. These people might use an SUV to carry a bicycle to a hilltop and then ride the cycle down. When you look at cycling as a sport, you cannot talk about environment. We should just appreciate it as any other sport. Running or walking is the most eco-friendly way to move from one point to another. But an Olympic runner need not be the most eco-friendly person on earth. Cycling as a sports completely falls into a different category.

Cycling is one of the most humble ways of moving around. Hence a cyclist can never be arrogant. By cycling, we are not saving the planet or fellow humans, we are trying to save ourselves.I

Humanure

Wednesday, July 1st, 2009

Currently I am reading this book – “The Humanure Handbook” by Joseph Jenkins. I am impressed.

If there is one thing human beings don’t want to talk about, it is their excreta. I don’t remember discussing managing the excreta with anyone – either at home or at school. All I knew about excreta was that it stinks and is host to millions of pathogens. Today it is “the thing” that is killing the planet.

We all know that excreta is organic in nature and just as any organic substance, under the right conditions and time frame, it will turn into humus. But we are putting our excreta in clean water and pushing it out of our house. In few cases the excreta is stored in a pit just in front of the house. But in most of the urban areas, it is ferried away for hundreds of kilometers just to be dumped in a river, with almost no treatment.

Nobody wants to own the waste created by oneself – let it be vegetable peels, plastic covers or human excreta. To start with, almost 60% of the Indians do not have safe drinking water. To add to this woe, people are building leach pits and allowing the waste water to seep down into groundwater sources. Human excreta contains all kinds of pathogens. If not treated properly, it can contaminate water sources and spread various diseases.

I keep saying this – People talk about HIV, but in India, number of deaths by dysentery and diarrhoea is greater. If we want, we can blame the government and continue shitting with our eyes closed. But the danger is looming. 70% of our rivers is polluted either with domestic or industrial waste. It is time to cut down this pollution. What is the option?

The best option which people would like is – treating the waste water. But this requires infrastructure to carry waste water from every corner to the treatment plant and huge amount of energy and chemicals to treat it.

The best option nature would prefer is – composting the waste – let it be kitchen waste or toilet waste. Daily Dump, a small initiative to compost kitchen waste is picking up in Bangalore. But most people fail to compost properly and complain about smell, flies and maggots. The key lies in keeping the mix dry by moist enough to encourage microbial breakdown. Composting is an art. If performed right, it can create the very essence of soil – HumusW

Human waste can be composted. The stinking excreta turns into fragrant humus within a year. The ‘How’ part of it is technical and lengthy to be put into a blog post. Good thing would be to read the Humanure handbook. Best thing is – it’s available free of cost.

In India, composting human excreta is done through ecological sanitation (EcoSanW). There are many villages near KolarW and MysoreW which are reaping the benefits of human compost. EcoSan is a dry toilet. You don’t need water to flush the excreta instead you deposit it directly in a pit. The urine is collected separately, stored, diluted and used on crops. The combination of human compost and urine replenished the fertility of the soil. Farmers don’t use fertilizers thereby avoid the damage imparted to nature in producing and using it. Humanure eliminates the need for clean water to carry the excreta and puts an end to the pollution caused by dumping human waste into rivers, lakes or leach pits.

Countries like Singapore are struggling to meet their water demands. Singapore recycles waste water to manufacture bottled drinking water.

Newater Bottle

Newater Bottle

But people have not accepted this form of recycling fully. Last week, our CEO, Sunita Nadhamuni got us a bottle of NewaterW from Singapore. I tasted the water and just could not find any difference. The problem lies in our culture – we treat our excreta as waste – but it is a precious resource that returns the fertility back to the soil that fed us. Singapore is ahead in thinking. Singapore does not use words like waste water treatment plants or water reuse. Instead it uses words such as Water Reclamation Plants or reclaimed water.

I am constructing an EcoSan at my house. It should be ready by September. I will update you all on my findings. In the meantime, you read the book and let me know about your opinion.

Oh the folly of Mankind!

Tuesday, June 30th, 2009

From past few days I have been reading about rain failure, power shortage and water problems. Bangalore Mirror posed a question to its users – “Should Bangaloreans take the issue of power shortage to streets just as Delhites?” Today 80% have responded saying ‘YES’. I wonder how many among that % really know the cause of power shortage.

Almost half of India’s electricity comes from coal and almost the other half from hydel power. Wind and solar power are still new concepts gaining momentum. So if rains fail, India drowns in darkness. The best part is the awakening of the bourgeois. All of a sudden bourgeois is showing concern – it wants electricity to run its televisions, ACs, treadmills and what not. These people must have domestic UPS right? Yes. Most of them do. But these UPS require 8-14 hours of power to charge completely. How can they charge 100% when there is intermittent supply? The best part is, for every 10 units an UPS absorbs, it gives away only about 7-8 units. 20% is lost in storage and reconversion. After 3.5 years, the entire fleet of batteries needs replacement, adding to the pollution caused by improper disposal of these batteries/chemicals.

Now that bourgeois has no option, it may retaliate. Delhi feeds on Tehri. Even then it has still not been able to meet its demands. How can we meet demand when the demand is on a constant rise with ever increasing population and frivolous needs?

I remember Nandan Nilekani’s words. I agree with him. We, the middle class, have created a parallel society of our own. We are not bothered about good education or transportation facilities because we can put our children into private schools and buy motorbikes and cars. We have even solved the problem of water with our own borewells and that of power with domestic UPS.

But we have forgotten the fact that we are connected to nature. How can your borewell suck water when nobody is worrying about recharging it? How can your UPS function when the electricity that charges it is dependent on rains? When rains fail, even government cannot do anything. China has tried chemical techniques for catalysing cloud formation and bringing home rain. But it cannot work on a larger scale.

This is a glimpse of our greed. The worse part is yet to come. Bangaloreans should worry about conservation of water, electricity and other resources. If we all protest, nature is not going to budge.

We are just worried about us. Think about all the living creatures that are on the brink of extinction because of severe deforestation. Think of all the people who get displaced in our country just because the urban population needs water and power. Think of all the damages made by our large dams – today they are dry – neither they have water nor they are producing electricity – these dams stand as a testimony of our ego and folly.

There are several options. We all can adopt solar and wind power. We have been using solar water heater at home. We use it for almost 330 days in a year. But now hybrid power is also an option – you can harness the power of Sun and Wind at the cost of Rs.2.2lakhs per house hold (after 50% govt. subsidy). Time to sell your extra car and worry about nature.

I am reminded of Jared Diamon’ds book – Collapse: How Societies Choose to Fail or SucceedW. It is time that we wake up and worry about our future not just today or tomorrow. Remember – someone else is paying for our comforts.

Interpreting Data

Friday, June 19th, 2009

India is one of the countries where getting access to public data is very difficult. Through RTI has enable the citizens to file an application and get data, the scale to which it can be used to get national level data is limited indeed.

Even straight forward data such as rainfall data is not available to public. Recently IMD agreed to put up last five years data in public domain.

Data plays a crucial role in research, policy making, planning and implementation of public works etc. In India, most of the time data is either generated by a private institute or an international institute. Very few government websites provide current and relevant data to public. Department of Drinking Water Supply is one of the few government departments putting up data for public use.

The next challenge with data is its presentation. Providing people with raw data is good, but everybody will not be in a position to interpret data. Data, if presented in the right format, can overturn laws and policies. One such effort has been enabled by Google’s Fusion Tables. Now that google has solved the problem of visualisation, we Indians should get back to the business of collecting data and making it publicly available.

Below is a very good representation of Total Renewable Freshwater Supply across the world. If you can observer, India is not doing bad. China is doing even better. But both India and China will soon be water stressed countries since we are not harvesting the rains to the best of our efforts. I am sure that once we overcome the challenge of collecting data and its visualisation, we would have to solve the greatest problem of humanity – convincing fellow humans to act in the right direction

Where is all the water going?

Monday, June 8th, 2009

With the advent of rainy season, with the frequent water logging, we might all be thinking that the planet has excess water and hence all the mess… But the fact is, our planet’s fresh water reserve is dwindling at an ever accelerating pace.

To begin with, let us look at the sources of freshwater – lakes, rivers, ice and groundwater. So what is happening with each source?

  1. Lakes – Lakes have been the traditional systems of harvesting rainwater – it is the nature’s way to store rainwater in a depression, which can be used in non-rainy days. But today, the catchment area of the lake as well as the lake itself is being encroached. Wherever the lake has withstood this attack, we are letting in our domestic waste into the lake and accelerating eutrophication
  2. Rivers – This source, since it is mobile, is suffering the largest possible damage. We are building dams and stopping water. This is affecting the entire ecosystem of the river. Many rivers are not reaching the oceans because of dams and over extraction of water. It is not just the over extraction but the contamination of rivers that is doubling the damage. Again, industrial and domestic waste is let into rivers without any treatment. Rainfall and Glacial melt – the two important sources of water for rivers – are changing their patterns. At some places, it seems that rivers seem to have more water than in the past. But it is the result of accelerated glacial melt. Rainfall pattern is shifting. Now oceans will carry more water than ever. This will alter the load balance mechanism of the planet. If oceans have to carry extra weight of water, it can trigger frequent earthquakes.
  3. Ice – Considering the climate change, we are not sure how long they can last. Fortunately, ice cannot be contaminated but can only be melted. But melting ice can completely change the current ocean levels.
  4. Groundwater – Over the last few decades, groundwater has been the most abused source of water. Apart from over extraction, the source is being contaminated with the constant seepage of harmful chemical of fertilizers, pesticides and soak pits. Today almost 70% of India’s water needs is met by groundwater. 85% of which goes towards irrigating crops. India’s farmers haven’t been very keen of optimizing the efficiency of water in agriculture. 40-50% of water goes underutilized. To add to all these woes, groundwater is not being replenished at the rate at which it is being extracted.

Blue Gold

Monday, June 1st, 2009

There is no other word that can aptly describe water – Blue Gold.

Today I was watching the movie – Blue Gold – World Water Wars. A must see movie for environment and water enthusiasts.

The movie starts with a true story of a Californian gold hunter – how his body got transformed into a quasi corpse in seven days because of lack of water. The story then moves on how we humans are using water without discretion. Here are some interesting statistics:

  1. Manufacturing an average automobile requires 350,000 liters
  2. Upto 7 barrels of water is required to extract a barrel of oil – Save oil to save water
  3. One microchip requires 32liters of water
  4. Today there are 50,000 large dams worldwide
  5. Today there are at least 10 publicly traded water indices
  6. 750 pounds of carcass requires 5.2 million liters of water – be a vegetarian and save water.
  7. 30,240 liters of water is required per 50pound bag of wheat! Don’t waste food my friends.
  8. 1.8 million liters per bale of cotton – Don’t buy too many clothes (don’t wear too less either)
  9. 77,500 liters of water is required per 50pound bag of rice. One kilo of rice requires 3,500 litres of water
  10. 99 liters for an apple
  11. 107 liters for a banana
  12. 22,000 liters of water per 50pound bag of corn
  13. 10 litres for a rose (more…)

I will find a place for us

Sunday, May 31st, 2009

Today I was listening to one of the Radiolab’s podcasts – Zoos

Personally I hate caging animals. But this podcast helped me understand how several people, knowing that zoos can never vanish, are trying to create better environment for caged animals.

Towards the end of the program there is a very inspiring story of Alan Robinowitz. As a teenager, Alan stared at a Jaguar in a zoo and said “I will find a place for us”. During next few decades, the stuttering teenager grew up into a man who changed himself and changed the lives of many wild animals.

We rarely hear about such people in India…the country home to 1/6th of world’s population.

Akshaya Trutiya – The new trend in south

Saturday, April 25th, 2009

Buying gold on Akshaya Trutiya is a new trend that has picked up in south only during recent years. Today’s newspapers are filled with ads to nudge people to buy gold. Many people believe that the amount of gold bought on this would double soon in the coming years fetching them fortune.

But I was wondering about the implications of these precious metals. Mining a single gram of gold would mean creating 5 tonnes of mining waste – that is 5000kg of mining waste. An gold earring would leave half a truck load of waste.

It is not just about environmental waste, but also the communities that get affected in the wake of our attraction to the glitter. Read this article from WorldWatch Institute for more details.

After watching Blood Diamond, I am sure, most of us would not have the tendency to buy Diamond, Gold or any other precious metal.

Are these precious metals so important to lead a happy life?

The era of nonviolence is over

Wednesday, February 18th, 2009

If it were not for the British, Gandhi would not have got the right attention for his nonviolence principle. I feel so more because of Indian government’s attitude towards nonviolent protests.

It has been close to 35 days. Prof. GD Agarwal has been on a fast-unto-death since Jan 14th this year. End of last year, Indian government declared the river Ganga as the national river. But the river has been the most sacred of all for the billion Indians since time immemorial. Government’s declaraton has done no good to the pathetic state of this river.

As we all know, the Ganga is fed with industrial and domestic waste throughout her journey to the ocean. But till 2006, she was spared till Hardwar. Now she is being chained just after 9km of her inception. She continues to be manipulated for every 10-15km till Uttarkashi. Prof. Agarwal’s only request is to allow Ganga to flow unhampered for first 125km.  When he first fasted in the month of June of 2008, central government said that it would look into the matter. The fast ended. But when neither the state government and nor the central government kept their promises, Prof. resumed the fast last month. The dam construction has not been halted.

So far, there have been several protests by NGOs and like minded people and organizations. But the govt. is busy in election preparation. I always keep saying this – the development projects in India help only two sections of the society – politicians and contractors. I fear that govt. would not brook to Prof.’s demand. The dams will be constructed. I hope Prof. Agarwal’s fight as well as life will not go wasted.
