The present study which started in 1999 is framed in the INCOYAM project. Marketing systems of yam are analyzed in three West- African countries: Cote d'Ivoire, Benin and Nigeria. Surveys have been carried out on urban (wholesales and retailers) and rural (collectors) traders. Cities and...

A socio-economic analysis of the farms in four villages of the Dikodougou region (North of Cote d'Ivoire) reviews two debates about the evolution of the farming systems in sub-Saharan Africa. Firstly, the two opposing views in the controversy "Boserup versus Malthus" are complements rather than...

The literature on the evolution of farming systems in West Africa shows a large diversity of general theories on rural development. The purpose of this study is to revisit the theses of Malthus and Boserup and empirically test them on a case study of Northern Cote dIvoire. We have at our...

A socio-economic analysis of a sample of farms in Northern Cote d'Ivoire revisits two debates about the evolution of farming systems in sub-Saharan Africa. Taking into account the diversity of farming systems, the debates "Boserup vs. Malthus" and "competition vs. complementarity" between cotton...

Crop protection is a part of the agricultural production system. In Europe during the past century, this system has been subject to innovation, stemming from the second agricultural revolution of the Modern Time. Today we are on the crossroad of three alternative agricultural systems....

We develop a theoretical welfare framework, which explicitly recognizes that research protected by intellectual property rights generates monopoly profits. The result is a simulation model, shaped to the European sugar sector, and enabling to assess the size and distribution of the benefits of...

Agricultural production almost needs to double in the 21st century, putting tremendous pressure on agricultural resources. Most food production increases must come from more agricultural intensification in the South. This advances the need for a new green revolution: higher productivity and at...

In this working paper we attempt to establish a general analytical framework for the calculation of the micro- and macroeconomic benefits and costs of biotechnology applications in EU agriculture. Since these innovative applications are typically protected by intellectual property rights,...

Some of the crucial assumptions of applied welfare economics do not hold any longer in the case of agricultural biotechnology innovations. We review some modifications to the conventional methodologies measuring the size and distribution of agricultural research benefits, which are critical for...
