What is the periphery? What is the centre? Who is to blame for these extremes (Centre / Periphery)? The countries of the world, even those living on the edge of poverty, want to grow and develop properly... and they're looking for a formula! It is to adjust the development formula that "Inclusion of Rural Areas for the Development of Southern Countries" appears. Nobody needs to travel long intellectual distances to find the formula anymore, because it's right here. Dear reader, you no longer need to try to find difficult formulas, because the simple Inclusion of Rural Areas that this book proposes is not intended to fail... Easy as that!
