Christian Aid has launched a new appeal to raise funds for its work in impoverished communities struggling even more in the global recession.

The aid agency aims to raise at least £1.5 million to help mitigate the impact of the recession and fluctuating international exchange rates on its income.

It said unfavourable exchange rates over the last 12 months had increased the cost of funding some of its overseas projects by as much as 20 per cent.

The charity normally only launches appeals to respond to specific humanitarian emergencies but said the recession had made it necessary to launch the unprecedented appeal to keep its work going.

Christian Aid says it needs to raise the additional funds by 19 February if it is to fulfil its planned work for 2010/2011.

Education, health and food are among the funds most in need of donations. Christian Aid will also use some of the donations for its general fund, which is used in communities where the need is greatest.

Paul Valentin, international director at Christian Aid said: “We understand the recession is hitting people in the UK, and this has been reflected in donations this year, however many of the people we work with in developing countries were already trying to survive on $1 a day before the financial crisis hit.

“Any increase, however small, in food and fuel prices mean they may be unable to afford the basics and need our support more than ever.

“Christian Aid usually only launches appeals in response to emergencies but the harsh reality is we need to raise additional funds to allow us to meet our commitments to poor communities around the world in 2010/11.

“Without these funds some very difficult decisions will need to be made before the new financial year so we are appealing to the generosity of our loyal supporters to make an exceptional cash donation.”
