Powerful plants: nature-based solutions in Asia

Jute: a natural alternative to plastic

The weather patterns in Bangladesh are ideally suited to growing jute, despite the changing climate. Jute was once a major source of foreign exchange but lost out to artificial fabrics. As we become more aware of the environmental dangers of plastics, jute is popular once more.

‘Retting’ the jute in water separates the useful fibre from the rest of the plan

Jute is an eco-friendly alternative to plastic because it grows quickly without the need for a lot of water or any artificial fertilisers or pesticides. It’s completely biodegradable and recyclable. It also absorbs carbon dioxide more quickly than many other plants. It even adds to the nutrients of the soil it grows in, rather than depleting them. Quite a roll-call of benefits!

We’re working with women in rural Bangladesh to build successful businesses from this extraordinary plant. Together, we’ve identified the fastest growing, most reliable varieties and we’re making sure there are plenty of seeds available to buy. We’ve sourced a simple machine which makes processing the raw fibre quicker. Unemployed young people are being trained in metalwork skills that enable them to manufacture these locally.

Plastic bags are banned in Bangladesh so there’s already a growing local market. Our work has also resulted in the development of new products such as sandals and yoga mats for the export market.

More than 400 women like Sheuli have taken our training and are now working for small and medium sized enterprises creating jute products. They have been able to gain some financial independence and improve their living conditions, all while improving the environment and reducing plastic waste.

Small is beautiful: climate-hardy seeds

Most people in Nepal rely on farming for food and income. Climate change has caused weather patterns to become more erratic, and many previously reliable crops can’t cope with the new conditions. Farming families are unable to grow enough to remain healthy and to earn a decent living.

The solution literally starts from the ground – with resilient seeds, better suited to changing climates and variable weather patterns. They produce delicious, spicy Nepa chilies; bitter gourd, a staple food that’s fed farming families for years; cauliflowers that can grow in even the toughest terrain; and hardy turnips, radishes and potatoes that grow all year round, even with extreme environmental challenges.

We’re working with farmers in Nepal so that it’s easier for them to buy climate-hardy seeds at a reasonable price. Training means they know when to plant them and how to tend them so that they stand the best chance of growing into big, healthy plants. And seed-saving techniques mean that farmers can create their own local ‘seed banks’, consisting of seeds perfectly suited to local conditions.

Green and mighty: bamboo biodykes

In Bangladesh and Nepal, climate change has caused monsoon flooding to become increasingly severe and unpredictable. People’s crops, property and businesses are destroyed by floods every year.

Biodykes are an environmentally-friendly alternative to normal flood defences, where ‘normal’ means huge concrete structures that are expensive to build, damage the environment and are catastrophic when they fail.

We’ve worked with communities in both Bangladesh and Nepal to build biodykes by strategically planting locally-available trees and other plants, such as bamboo. The biodykes bind the soil and help prevent erosion, maintaining the original flow of the river, while also preventing the river from overflowing after heavy rainfall.

Biodykes deliver economic, environmental and social benefits. They really are a win, win, win solution – unlocking the triple dividend of resilience in terms of saving lives and avoiding losses when disasters strike, stimulating local economic activity, and delivering additional development co-benefits.

Biodykes have been instrumental in protecting communities’ homes, agricultural land and public infrastructure, reversing the annual cycle of flood losses and increasing the confidence of communities to invest in long term land and farm productivity.

What’s next?

COP26 will be biggest summit ever hosted in the UK, with around 30,000 attendees expected in November 2021. It’s been described by climate change experts as the most significant climate event since the 2015 Paris Agreement. That’s because COP26 is the first moment when countries must report back on their progress since the Paris Agreement and set out more ambitious goals for ending their contribution to climate change.

One of our major roles is to balance things out by making sure voices from the Global South are heard. Our team will be on hand to listen to the negotiations and to help delegates from less developed nations provide research, evidence, examples and testimony to show the impact of climate change on their populations and the value of nature-based solutions.
