Member agencies of the Disasters Emergency Committee have warned that levels of malnutrition are "alarmingly high" in children living in parts of Darfur and Chad that are plagued by chronic food shortages.

They are urging the public to keep giving generously so that vital medicines and medical equipment can be stocked before the heavy rains arrive in parts of Darfur and Chad.

According to a recent nutrition survey by Tearfund at El Neem camp in Ed Daien, South Darfur, 30 per cent of babies are malnourished - double the level considered to be an emergency. The situation has been described as "deeply serious" by Tearfund, who say the problem has been made worse because at least 30,000 new arrivals have poured into the camps in the last few months.

Nigel Timmins, Tearfund's Operation Manager for Darfur, said: "I was at the El Neem camp a few weeks ago. Mothers sat there with their children. To them their child is the centre of their universe and to not be able to feed them is heart breaking. It's such a basic instinct to want to take care of your child, and they desperately need to know that someone is going to look after them. By supporting this appeal, you really are saving lives and keeping families together. I believe we have a moral obligation to stand with them- they're real people caught up in an ongoing conflict. They have lives, hopes and futures, and we need to persevere and see this through."

Tearfund has been working in Darfur since 2004, providing vital feeding programmes, ensuring people have access to water and sanitation, educating people about health and hygiene and making sure people have seeds and tools to begin to be able to feed themselves.

By donating just £80, you could feed five critically malnourished children for one month. Aid agencies such as Tearfund are on the ground and can help save lives with your help.
