Food for nutrition, nature and livelihood

What societies eat reflects their position on the modernity trajectory. Poorer countries have health problems because of lack of food. Then as people get rich, they end up losing the health advantage of food availability. They eat processed food that is high in salt, sugar and fat, which make them obese and ill. It is only when societies get very rich that they rediscover the benefits of eating real food and value sustainability.

Promise me the monsoon

Why this weird weather? Why have western disturbances—the extra-tropical storms that originate in the Mediterranean and Atlantic seas—been lashing us again and again, with devastating impacts on agriculture? Is this normal? Or has weird weather become the new definition of normal?

How to plant trees for development

Today, in India, forest protection happens against all odds. There is no economic value seen in forests, but there is value seen in the development project for which forestland is required. Clearly, this is not the way to go. We need a value to be paid for standing forests; it needs to be shared with people who inhabit these lands; we need to grow trees in ways which bring money to the poor; and we need to learn how to protect, regenerate and grow trees, all at the same time.

Straw in the wind

What does the decision to save groundwater in Punjab or Haryana have to do with air pollution in Delhi? Plenty. We need to know this because many actions have unintended and deadly consequences.

Walk the talk on carbon tax, Mr Finance Minister

Budget 2015, presented by Finance Minister Arun Jaitley, has a first. In it, India has accepted that it has a de-facto carbon tax—on petroleum products and dirty coal. Arguably, the only big green initiative of this budget is the increase of cess on coal—from Rs 100 per tonne to Rs 200 per tonne. But the question is: is this carbon tax, imposed on the carbon content of fuel, doing what it should—reduce greenhouse gas emissions that are responsible for climate change?

How power can be cleaned

Coal is an environmentalist’s bugbear. The use of coal to generate energy is the key reason the world is looking at a catastrophic future because of climate change. Recognising this, global civil society has given a rousing call for coal divestment, asking companies, universities and individuals to stop investment in coal thermal power plants. They want coal to go, renewables to be in. And in the interim, clean gas, also a fossil fuel, to be used as a “bridge fuel”. In this scenario any talk of “cleaning” coal to make it less damaging is untenable.

Time for new environmentalism

 2014 has brought India’s environmental movement to a crossroad. On the one hand, there is a greater acceptance of our concerns, but on the other hand, there is also growing resistance against the required action. More importantly, every indicator shows that things on the ground are getting worse. Our rivers are more polluted, more garbage is piling up in our cities, air is increasingly toxic and hazardous waste is just dumped, not managed. Worse, people who should have been in the front line of protection are turning against the environment.

Real pride of ancient indian science

I write this with considerable impatience and one question. Do we really have the time to waste on controversies like what ancient India did or did not achieve by way of scientific discoveries? This is when there is the huge unfinished agenda to use the best of science to tackle current challenges and crises.

India's climate strategy needs revision

 Climate change negotiations are by now predictable. The already-industrialised come to each conference of the parties (COP) with a clear game plan, that is, to erase their contribution to the emissions already present in the atmosphere, thereby effectively remove the differentiation between their responsibility and that of the rest of the world to act. This would rewrite the 1992 convention on climate change and let them evade the obligation to provide funds and technology for action in the developing world.

So that we can breathe easy

THE EASIEST way to clear air pollution is to not know how bad it is. This is what India practices—in most parts of the country. There is virtually no equipment to monitor the air we breathe and no system that tells us what we should do when pollution levels are up and unhealthy.

Last call to get climate deal right

The Indian government must not use “equity” to block climate change negotiations. It must be proactive on equity and put forward a position on how to operationalise the sharing of the carbon budget—accounting for countries’ contribution to past emissions and allocating future space—in climate talks. I wrote this last year when the UPA government was in power. I am repeating this as the NDA government prepares for the next conference of parties (CoP) to be held in December in Peru.

Making sense of green building rating

The building sector is set to grow exponentially. It already has a huge environmental footprint, with the domestic and commercial sectors consuming some 30 per cent of India’s electricity. So, the imperative to go green is clear. The question is where India is and where it should go. The Bureau of Energy Efficiency (BEE) has issued the Energy Conservation Building Code (ECBC) to improve the energy performance of buildings by 40-60 per cent. But the use of the code in design is not linked to the actual performance of the building after it has been commissioned.

Ozone-smart, climate-cool

One item on the agenda of the much-discussed Narendra Modi-Barack Obama meeting that has Indian commentators flummoxed is hydrofluorocarbons (HFCs). The joint statement issued after the meeting of the two heads of states says rather ambiguously that the two sides agreed to cooperate on “next steps to tackle the challenge posed by HFCs to global warming.”

The myth of green building

There is no question that India and other parts of the still-under-construction world must build green. The building sector is a major contributor to climate change and local environmental destruction because of construction materials used; energy expended for lighting, heating and cooling; and water consumption and waste discharge. This is the threat. There is an opportunity as well.
