earthrise sets off to South Africa and Nepal to see how some newly developed solutions are helping farmers to produce food for a growing population as conditions change. 

Surviving drought in South Africa

South Africa has been experiencing the worst drought in 100 years. Since the 1990s the country has lost a third of its farms because of water scarcity. As a result, farmers have had to turn to a hi-tech solution to help cope with dwindling water supplies and harsher environments.

Professor Jill Farrant, a professor at the University of Cape Town, who has been trying to unlock the secret behind so-called resurrection plants which can survive long periods without water. He believes they may hold the answer to crops surviving long periods without water.

On the De Wet family farm they have employed cutting-edge technology called Fruitlook to help run their orchard effectively. The system uses NASA satellite imagery which takes monthly pictures showing soil health and dry areas. As a result, farmers are able to target irrigation to areas that really need it, thus saving water.

Nepal's plant clinics

As trade has become more globalised, so too has the movement of pests from one country to another. Together with a changing climate that has become suitable for pests, this has meant that smallholder farmers in Nepal are having to cope with new problems threatening their crops.

In Pokhara, Nepal, there is a new initiative called Plantwise, which sets up clinics to advise and aid farmers in ridding farms of pests with eco-friendly methods.
