TANZANIA – The European Union on Tuesday will pledge 43.6 million euros ($51.5 million) to help meet emergency aid and food needs to three countries in Africa’s Sahel region, as the United Nations sought to raise $1 billion to tackle a humanitarian crisis there.The offer came as part of a virtual ministerial meeting -- hosted by Denmark, Germany, the European Union and the United Nations -- aimed at spotlighting one of the world’s fastest growing humanitarian crises in a region plagued by increasing conflict, weak governance, and a lack of development.“The EU’s pledge consists of 23.6 million euro in funding for humanitarian actions in Burkino Faso, Mali and Niger, and 20 million euro in development funding to address the food crisis.
