Purple revolution: India’s farmers turn to lavender to beat drought

Posted on by

Faced with climate change, farmers in Jammu and Kashmir are switching from maize to essential oils

It’s late June and the field is glowing with fragrant purple as the women in their flowing shalwar kameez arrive with scythes to harvest the lavender. In the 30-odd villages on the hilly slopes of Jammu’s Doda district, more than 200 farmers have shifted from maize to lavender production, starting a “purple revolution” in the region.

The village of Lehrote had a moment of agricultural fame this year when a 43-year-old farmer, Bharat Bhushan, won a prestigious award for innovative farming from the Indian Agricultural Research Institute, one of several institutions across the country looking to find ways of coping with the climate crisis and its devastating impact on farming. Lavender, a drought-resistant crop, can be grown on poor soil and likes lots of sun but needs little water.

Action on the climate crisis must come with a social contract to protect the poor and vulnerable


As a climate policy researcher, I am often asked: what is the biggest obstacle to decarbonisation? My answer has changed profoundly over the last couple of years. I used to point to the lack of affordable green technologies and an absence of political will. Today, I point to something else. Something less tangible, but possibly more challenging: the absence of a green social contract.

The green revolution is already unfolding, driven by a stunning reduction in the cost of green technologies and by a global momentum for climate neutrality by the mid-century. So, if cheaper green technology and an unprecedented political green ambition are rapidly converging, what could go wrong? Unfortunately, the situation is not as simple as it seems. Decarbonisation will reshape our economies and our lifestyles. Nothing will be left untouched in the process: the green world will be profoundly different from the one we know today.

The rice of the sea: how a tiny grain could change the way humanity eats

Ángel León made his name serving innovative seafood. But then he discovered something in the seagrass that could transform our understanding of the sea itself – as a vast garden

Growing up in southern Spain, Ángel León paid little attention to the meadows of seagrass that fringed the turquoise waters near his home, their slender blades grazing him as he swam in the Bay of Cádiz.

It was only decades later – as he was fast becoming known as one of the country’s most innovative chefs – that he noticed something he had missed in previous encounters with Zostera marina: a clutch of tiny green grains clinging to the base of the eelgrass.

China’s vast bitcoin mining empire risks derailing its climate targets, says study

Posted on by

China powers nearly 80% of the global cryptocurrencies trade, but the energy required could jeopardise its pledge to peak carbon emissions by 2030

China’s electricity-hungry bitcoin mines that power nearly 80% of the global trade in cryptocurrencies risk undercutting the country’s climate goals, a study in the journal Nature has said.

Bitcoin and other cryptocurrencies rely on “blockchain” technology, which is a shared database of transactions, with entries that must be confirmed and encrypted. The network is secured by individuals called “miners” who use high-powered computers to verify transactions, with bitcoins offered as a reward. Those computers consume enormous amounts of electricity.

Best served chilled: green tech keeps the cool on India’s dairy farms – photo essay

Posted on by

Photographer Prashanth Vishwanathan captured a network of community dairies helping off-grid farmers in Maharashtra keep milk fresh as temperatures rise. All pictures are from Climate Visuals

As global temperatures climb, a lack of refrigeration makes a big impact on people trying to make a living from farming. Especially dairy farms.

There are more than 75 million smallholder dairy farmers in India. Most are in off-grid areas without refrigeration, or reliant on expensive and polluting diesel generators. This locks people out of national supply chains, and farmers have to spend hours transporting milk to markets, or sell at a lower price to middlemen. In Maharashtra, western India, a network of community dairies has been set up, using sustainable refrigeration technology, where people can bring their milk to be tested, chilled, and sold on.

Rewilding our cities: beauty, biodiversity and the biophilic cities movement

Buildings covered in plants do more than just make the cityscape attractive – they contribute to human wellbeing, biodiversity, and action on climate change

Our cities are dominated by glass-faced edifices that overheat like greenhouses then guzzle energy to cool down. Instead, we could have buildings that are intimately connected to the living systems that have evolved with us, that celebrate the human-nature connection that is central to our wellbeing.

As more of us in Australia live in urban areas and our cities grow, bringing nature into our cities is a key part of establishing and rebuilding that connection. As well as bringing beauty into urban environments, we know that people are healthier when they are connected to nature. Research also shows that crime rates decrease in areas with street trees and that property values increase.

Experts say extreme weather including droughts will become more common as planet heats

Recent sandstorms that shrouded Beijing in a post-apocalyptic orange haze and intensive droughts in other parts of the country are bringing into stark relief the challenges China faces from rising temperatures induced by the climate crisis.

The widespread sandstorms that pelted the capital and spread as far as central China for several days in mid-March and again at the end of the month were brought on by lower than average snow cover and precipitation, as well as higher than normal temperatures and winds across Mongolia and northern China.

Economies are gearing up for return to fossil fuel use instead of forging green recovery, warns Fatih Birol

New energy policies are urgently needed to put countries on the path to net zero greenhouse gas emissions, the world’s leading energy economist has warned, as economies are rapidly gearing up for a return to fossil fuel use instead of forging a green recovery from the Covid-19 pandemic.

Most of the world’s biggest economies now have long-term goals of reaching net zero by mid-century, but few have the policies required to meet those goals, said Fatih Birol, the executive director of the International Energy Agency (IEA).

After bottles were recovered in top shape from a first world war shipwreck, winemakers have started to exploit the sea’s cool, dark environment

Slipping into the chilly waters of the Baltic sea, the divers descended more than 60 metres to where the masts of the Jönköping lay strewn across the seabed. They glided past the wounds left when the Swedish schooner was sunk by a German U-boat in 1916 to home in on the rare treasure they had come for: thousands of bottles of 1907 Heidsieck champagne.

Dutch Green Business, which plants trees for carbon capture, says ex-Ukip leader will ‘facilitate introductions’

He has criticised Greta Thunberg for “alarmism” and wind power as “economic insanity” – but Nigel Farage appears to have made a U-turn on climate change, after signing up as a lobbyist for a Dutch green finance firm, in his first commercial role outside frontline politics.

Dutch Green Business Group, which is listed on the Amsterdam stock exchange, said it had appointed Farage to its new advisory board. The eurosceptic and former Ukip leader will “facilitate introductions to politicians and business leaders in the UK and around the world” while also acting as a spokesman for the company, it said in a press release.

One of Earth’s giant carbon sinks may have been overestimated – study

Posted on by

The potential of soils to slow climate change by soaking up carbon may be less than previously thought

The storage potential of one of the Earth’s biggest carbon sinks – soils – may have been overestimated, research shows. This could mean ecosystems on land soaking up less of humanity’s emissions than expected, and more rapid global heating.

Soils and the plants that grow in them absorb about a third of the carbon emissions that drive the climate crisis, partly limiting the impact of fossil-fuel burning. Rising carbon dioxide levels in the atmosphere can increase plant growth and, until now, it was assumed carbon storage in soils would increase too.
