At a fundamental level, biotechnology is directed at manipulating energy flows, especially those in agriculture. Improved crop varieties, disease and pestcontrol, as well as nutrient enhancement can be achieved by it. Biotechnology thus contributes
The role of forest ecosystems and wood in controlling the absorption and emission of carbon dioxide
of trees to pests and diseases; 3) as a benificiary of global changes thanks to the fertiliser effect; 4) as a remedy for global changes thanks to their ability to sequester carbon. The role of forests depends thus on methods of management and the ways

Vers une approche individu-centrée pour modéliser et simuler l'expression spatiale d'une maladie transmissible : la peste à Madagascar
L'enjeu actuel des recherches porte davantage sur l'analyse des processus d'émergence, de réemergence, de diffusion et de conservation de la peste, ce qui suppose de replacer la maladie dans son environnement, afin de mieux la contrôler. Les AA

This parasitic disease has a marked potential for eradication through a combination of water supply management, health education, and controlled medical intervention. These methods require the development of water wells and establishment of schools
. A model is developed to determine the best locations for the different types of facilities used to fight the disease.

A private Contagious Diseases Act : prostitution and public space in Victorian Cambridge
En Grande-Bretagne, le contrôle de la prostitution est devenu une question urgente au milieu et à la fin du 19ème siècle, ainsi que l'indiquent les Contagious Diseases Acts. La politique de contrôle a été d'abord menée par l'Université de Cambridge
. L'A. analyse la nature de ce système de surveillance. Il étudie l'origine sociale et l'expérience des prostituées. Ce système de contrôle considéré comme autoritaire et anachronique a été critiqué.

The reinfestation of malaria of northern Argentina is analysed, from the point of view of the trends in incidence during the period 1937-89 and especially the increase after 1970. Control measures are also proposed.

Same disease—different research strategies : Bananas and Black Sigatoka in Brazil and Colombia
Using the cases of Brazil and Colombia, this paper examines different agricultural research responses to the Black Sigatoka disease. Brazil opted to replace susceptible varieties with resistant ones, whereas in Colombia chemical control by private
