Genetic advance to ensure future of high-protein crop

Millions of people in developing countries may benefit from a breakthrough in chickpea farming thanks to an international research team involving researchers from the University of Western Australia, CSIRO and other Australian research groups.

The goal of the Indian-based International Crops Research Institute for Semi-Arid Tropics (ICRISAT) project was to decode the genomes of 90 chickpea genotypes. Apart from Australia and India, the international effort also involved scientists from the USA, China, Canada and Europe.

The study – recently published in Nature Biotechnology – is significant because chickpea seeds are a major protein and nitrogen source for people living in the semi-arid tropics such as parts of India and the African countries, Ethiopia, Tanzania and Kenya.

Chick pea crops provide high-quality protein and cash income to resource-poor farmers, and fix nitrogen in the soil, which improves fertility.

Chickpea is the second-most widely grown legume after soybean and was the major grain legume crop grown in Australia last year.

The research team discovered millions of genetic markers that may be used in the development of chickpea that is higher yielding and more resistant to drought and disease. This will help chickpea farmers to be more resilient to climate change.

Like many other common crops, chickpea has a narrow genetic base because of domestication. In much of the world, chickpea is grown in semi-arid places and on poor soil which – combined with its susceptibility to drought and disease – have restricted yields to below its theoretical potential.

In the study, researchers re-sequenced and analysed the genomes of chickpea from 10 countries. The study covered small-seeded ‘desi’, larger-seeded’ kabuli’ and wild varieties.

The Australian contribution, led by Winthrop Professor Karam Singh, of the University of WA and CSIRO Plant Industry, was funded by the Grains Research and Development Corporation (GRDC) with further scientific contributions from the CSIRO, Curtin University and the University of Queensland.

Make your next holiday a sustainable one

Rosemary Black

It’s holiday time and many of us are heading off overseas, or thinking about where to spend our next vacation. Our choice of destination, accommodation and activities can make a difference to local economies, cultures and environments. Dr Rosemary Black offers some advice on how we can make our holidays more sustainable.

Eco-tourism is a major source of income, supplementing subsistence fishing and farming.

For developing countries like Fiji, Thailand and Indonesia, tourism is a major source of foreign income and a potentially significant driver for economic growth. So, while we often hear about cases where tourism may have detrimental impacts on the local environment and communities, it can also provide positive benefits.

Sustainable tourism is tourism that is environmentally, economically and socially sustainable – that means its aim is to minimise impact on the environment and communities, and at the same time contribute positively to local communities.

What can you do to ensure that your tourism experiences are sustainable?

The first thing is to realise you are a vital part of the global tourism industry, and you can help transform the way the world travels by being a responsible traveller.

As a tourist or potential tourist, ask yourself ‘am I contributing to the local community or environment?’ Travel can and should be much more than simply visiting places, taking pictures and buying souvenirs; it can inspire cultural awareness, tolerance, and commitment to environmental responsibility.

Try to minimise your impact on communities and the environment. One of the most important things you can do as a responsible traveller is to make informed choices before and during your trip. With a little planning, you can improve the quality of your trip, while making a real difference to the people and places you visit.

When choosing destinations, accommodation and tour operators, consider which ones work to protect the environment and benefit local cultures and communities.

Do your homework, ask questions, seek out quality products by looking for accredited operators, guides and accommodation, and look for opportunities to give something back to the local community or environment – many tourism operators are supporting community projects and offering travellers the opportunity to get involved.

By exploring alternative travel choices, you can have a unique trip and avoid leaving negative marks on cultures, economies, and the environment, while making a positive impact on the people and places you visit.

Here are some useful dos and don’ts for your next trip away from The International Ecotourism Society. These are useful for holidays in Australia and overseas.

1. The hotel: Ask about environmental policies and practices. Talk with staff about working conditions. Does the hotel support community projects?

2. Language: Learn a few words of the local language and use them.

3. Dress: Read up on local conventions and dress appropriately. In many countries, modest dress is important.

4. Behaviour: Be respectful of local citizens’ privacy. Ask permission before entering sacred places, homes, or private land.

5. Photos: Be sensitive to when and where you take photos/video of people. Always ask first.

6. Environment: Respect the natural environment. Never touch or harass animals. Always follow designated trails. Support conservation by paying entrance fees to parks and protected sites.

7. Animal products: Never buy crafts or products made from protected or endangered animals.

8. Pay the fair price: Don’t engage in overly aggressive bargaining for souvenirs. Don’t short-change on tips for services.

9. Buy local: Choose locally owned lodges, hotels, and B&Bs. Use local buses, car rental agencies, and airlines. Eat in local restaurants, shop in local markets, and attend local festivals/events.

10. Hire local guides: Enrich your experience and support the local economy. Ask guides if they are licensed and live locally. Are they recommended by tour operators?

A book I recently co-edited explores the issues of how sustainable tourism can provide positive benefits to local people and the environment in developing countries. Sustainable Tourism and the United Nations’ Millennium Development Goals: Effecting Positive Change brings together research and examples from around the world of sustainable tourism initiatives.

The UN Millennium Development Goals focus on trying to address global issues like poverty alleviation, primary health care and education for all, environmental sustainability and gender equity. We used this as a framework for the book and explored how sustainable tourism can help support and meet the goals.

We didn’t only have academics writing chapters but sought out local people who actually run sustainable tourism operations in places like Nepal, Costa Rica, Fiji and Indonesia.

I think this book has an important message for tourists from developed countries such as Australia who travel overseas to enjoy the different culture and environment of a developing country – that they can play an important role as responsible tourists and that tourism can help support the health and well-being of local people, assist biodiversity conservation efforts, and preserve local cultural heritage, while also supporting education, equal opportunities for women and basic human rights.
