The southern fringes of the Sahara desert host rugged lands where mankind has thrived for more than a millennium. In this vast panorama, the Inner Niger Delta stands out: In a region where limited rainfall is a fact of life, the Delta is a natural dam and irrigation scheme whose flood plain creates a grazing and cropping perimeter that at its peak can reach 30,000 km2 and sustains about 900,000 people.

You could be forgiven if you found deworming to be something of an enigma.  Some have hailed it as one of the most cost effective interventions for improving school participation in developing countries.

Inequality is of concern for at least three reasons. First, lower inequality per se is an objective for a decent society. Second, lower inequality improves the efficiency of economic growth in achieving poverty reduction. Third, high inequality impedes growth itself, through its impact on social cohesion and the investment climate.

“I am always hungry, as oftentimes my family and I skip meals. I want to go to school like my friends, but my parents always say it is too expensive. If I go to school, then I can’t work to help them buy food, and then I am hungry again. I am helpless when it comes to changing my situation, I have no voice and there are few people that see things the way I do.”
