Although the awareness of the environmental damage caused by plastic pollution has recently increased, few steps have been taken to confront its consequences. These consequences are often most severe in the Global South where countries often lack proper waste management infrastructure. Unless the market value of plastic waste increases, it will simply be discarded, eventually making its way to the environment. It has been established that polyolefin plastic can be converted to a sulfur-free fuel oil by pyrolysis, suitable for use in diesel engines or as a clean cooking fuel. However, carrying out this chemistry in the Global South is challenging. Any process intended for use in the Global South must be safe, robust, efficient, simple to operate, low cost, and most importantly profitable for the operator. When the average daily wage in sub-Saharan Africa is less than 3 USD, an income provided from plastic waste fuel can be significant. The research presented herein focuses on the optimization of a plastic-to-fuel processor that can be built using the principles of appropriate technology. The results of this optimization and profitability assessment will be described. This research has been conducted in collaboration with the NGOs Empowered Solutions for Environmental Sustainability and UpCycle Africa.

This paper presents a model of development that is driven by matching between talents and technologies. Differences in productivity across countries are amplified by three dimensions of talent utilization: the range of talents utilized, the density of a specific talent utilized, and the average match quality in the economy. In our model, higher productivity increases the number of technologies available, enhancing the opportunities for individuals to match their talents to specific technologies and increasing the returns to search. More intensive search further contributes to talent utilization.

Introduction. Les oasis marocaines sont réputées pour le savoir-faire ingénieux de leurs habitants en matière de gestion et de préservation des ressources naturelles. La datte, principal produit des oasis, bénéficie amplement de cette ingéniosité qui connaît, de nos jours, une régression et un manque de valorisation. Notre étude a eu pour objectif d’archiver et d’analyser le savoir-faire de la transformation des dattes en jus, localement appelé Tassabount, et d’en proposer un mode de valorisation. Matériel et méthodes. La méthodologie employée pour le travail d’archivage et d’analyse des connaissances locales de transformation des dattes en jus a été basé sur une approche participative impliquant une centaine de femmes oasiennes de la vallée du Drâa (Maroc). Résultats et discussion. Notre étude a mis en évidence une pratique ingénieuse dans la transformation locale des dattes en jus. Ce savoir-faire, développé par les femmes oasiennes, est étroitement lié à la diversité génétique du palmier dattier (variétés et hybrides). En outre, le Tassabount est identifié comme produit prometteur à valoriser, en misant sur ses qualités organoleptiques et ses vertus thérapeutiques. Par ailleurs, la description et l'analyse du procédé familial de préparation du Tassabount ont permis d’identifier des voies possibles d’amélioration pour son élaboration et sa stabilisation en vue de son transfert à des entreprises artisanales et/ou industrielles.

In the years prior to independence, farmers had access to the international market through the production of export crops which at that time received considerable input from research. Access to export crops has dwindled, support for research by national governments is disappointing, human resource development is inadequate, donor funding is uncoordinated, and the food crisis has taken on political dimensions. The assumption that direct importation of western technology can solve the problems of Africa is no longer valid in the face of several failures. The challenge to national agricultural research systems and the problems associated with the generation or adapting of farmer-oriented, location-specific technologies for sustaining agricultural production are discussed. Examples are drawn from India and an agenda for action, involving national governments, the international agricultural research centres and donors, in resolving these problems is presented.
