Sustainable development programs in third world countries, generally bankrupt, are characterized by the marginalization of peasantries, urban poverty, food deficit, destruction of infrastructure and the environment, failure of endogenous industrialization , over-indebtedness of States, mismanagement of available resources and potential, inter-ethnic conflicts, repeated rebellions and wars, corruption, theft and embezzlement.The question we ask ourselves on this subject is whether the programs and projects were poorly designed, poorly developed, poorly carried out or executed? or is there a lack of follow-up in execution to plunge populations into impoverishment which requires the intervention of external aid? According to the analyzes carried out, it is important that the notorious inefficiency of all these projects is linked to errors in the precision and choice of activities, design, development, monitoring and evaluation of the projects. This situation sufficiently reflects the non-existence in third world countries for decades of a good system of the process through which our projects must go.
