Policy makers have welcomed the $3 billion pledge by US President Barrack Obama to fight poverty on the African continent.They are however hoping the pledge will not come with its own conditionalities as has been the case in previous pledges.Obama made the pledge during the ongoing G8 Summit in US, Friday, hoping the amount will lead to food security and a Green Agriculture Revolution in Africa.President John Mills who was one of four African presidents at the summit pledged his government's commitment to ensure food security not only in Ghana but on the continent as a whole.But policy makers have cautious about the pledge.Advocacy Manager of International NGO Oxfam, Mohammed Sadat Adam, told Joy News’ Evans Mensah on Top Story the pledge should be linked to what Africa wants to do and not what the G8 wants Africa to do.He said G8 must not only make pledges but must be seen to redeem their pledges.According to him, a similar pledge of $22 billion over three years was made by the same G8 in 2008 but less than half of the pledge has been made available.He said the continent must begin to look at innovative ways of solving the problem of food insecurity on the continent.The General Secretary of the Agricultural Workers Union Edward Kariwe also reiterated the need for Africans to choose which areas in agriculture to invest the amount pledged.Whilst he believed that Ghana is not close to a famine situation, he was quick to add that the country must increase its production capacity.
