La densification rapide des groupes à revenu intermédiaire dans les économies en développement est certainement un événement majeur du début du 21e siècle (Kharas, 2010). Ce projet de recherche a pour objectif de proposer un examen approfondi des classes moyennes, de leurs caractéristiques, comportements, aspirations et attentes, ainsi que des impl...
This paper makes a first attempt to estimate the evolution of income inequality in Africa from 1990 to 2017 by combining surveys, tax data and national accounts in a systematic manner. The low quality of the raw data calls for a lot of caution. Results suggest that income inequality in Africa is very high, and stands at par with Latin America or In...
Dans le monde de l'irrigation, la région de Marrakech est connue pour l'ancienneté et la complexité de réseaux de canaux de surface, les seguias, alimentés par les oueds du Haut Atlas et de réseaux de galeries drainantes, les khettaras, qui ramènent en surface les eaux de la nappe phréatique. Dans les années 1970, la gestion de ces ouvrages hydraul...
When the Amazonian rain forest is cut to create pasture, some of the original vegetal species survive clearing, even expressing their ability to invade agro-systems.

The comparison of little fall and its decomposition in rubber monoculture and rubber agroforestry plantations were study and were conducted at Si Banphot and Srinagarindra districts, Phatthalung province from October 2016 to April 2017. The mature rubber cultivar RRIM 600 clone with age around 10-30 years were selected to study in monoculture and r...
In this chapter, based on re-analysis of previous published data, we study the biomass, trophic component and size structure of the zooplankton in the Sontecomapan Lagoon, in order to better evaluate its trophic status and assess its possible incidence on food transfers, eutrophication and terminal productivity in this lagoon. Our results show very...
