African botanical heritage for new crop development

The African continent is rather poor in plant biodiversity when compared to other continents on and around the equator. Nevertheless, lots of useful plant species have been domesticated from Sub-Sahara Africa material. Ethnobotanical research offers the possibility to collect information on use and utility of wild plant species from traditional people often living in or close to a challenging natural environment. This type of information then allows us to find new candidates for domestication and subsequent crop development for income generation and increased food security. The case of Gnetum africanum illustrates the practical implications of developing a lesser-known species, and highlights the institutional problems that go together with niche crop development. The latter are subsequently presented and discussed in extenso, and solutions proposed in a second part of this review text

Regional Mortality Differentials in IIASA Nations

This paper examines and summarizes the rich stock of regional mortality data collected for IIASA member nations by the Comparative Migration and Settlement Study. Regional mortality differentials are analyzed by comparing regional mortality rates and by constructing, for each country, an overall index of regional differentials. The principal conclusion reached is that there still are rather striking regional differentials in mortality among IIASA member nations

Migration and Settlement in Canada: Dynamics and Policy

In this report, the author analyzes the regional demographic changes in Canada. The investigation on a provincial basis leads him to draw attention to some very important implications of recent demographic behavior of the population and to propose a more rigorous population distribution policy
