How, since 2006 when the organic law on the finance law entered into force, has the figure become the centrepiece in a way of governing where the political decision is subjected to a logic of result? The author wonders about the current hold of the management evaluation over the definition of the governmental activity. He shows how it makes the democratic practices lose their strength. It addresses the forms of resistance that civil servants and citizens can use to oppose this erosion.

This book champions the idea that it is possible to achieve plentiful agricultural production whilst improving the quality of the environment. It discusses the various specific features of ecologically-intensive agriculture, sets out the changes in the concept and states the means of expanding the use of ecological functionalities for agriculture and animal husbandry. It addresses the conditions for global economic and social viability, seen as a factor in successful ecologically-intensive agriculture. Based on a panel with very wide experiences, this work will fuel the debates between agricultural professionals and environmental groups so that farmers themselves become true champions of the agricultural biosphere.
Fruit of the photosynthesis of plants, the biomass is an essential resource for humans, supplying them with food, energy and materials. With its three sources (forest, crops and waste), the energy-biomass is restricted by the production capacity of soils and its competition with its other uses. Could it therefore contribute to the growing energy needs of humanity and to the energy transition that must take place to reduce our oil and gas consumption substantially?
This practical guide presents the different stages in mango processing, from fruit delivery to dried mango marketing. The authors have included various diagrams and designs.
This work is a compilation of the most recent scientific thinking. It attempts to assess whether man can still adapt to the consequences of his own action on the environment and moderate his thirst for "always more".Eminent researchers present results that are sometimes alarming, often puzzling and occasionally reassuring. The work addresses in succession the biological abilities of the human species to adapt and their limits, the consequences of our activity on the environment and the margins for manoeuvre available to us. It develops premises for solutions and the scientific, ethical and philosophical interrogations they generate.
This book traces the history of birds right back to their reptilian origins. It underlines their homogeneity - flight, beak, skeleton and feathers are a bird's reference points - without losing sight of their diversity. Morphological and biological diversity (reproduction especially), but also adaptative. How do they withstand the cold and the predators, how do flightless birds run, how do you fly when you are a vulture? This book explores the intimacy of birds whose habits awaken the curiosity - the Grey Cuckoo, certain species of pigeon or the Hamerkop. It also discusses the relationship between humans and birds.
How can the presence of rocks from the oceanic crust in the French mountains be explained? How can we decode their long history from their birth within the oceans, their burial in the depths and then their rise to the surface? This work will serve as a geological guide for anyone wishing to explore these rocks on the ground.
Although the French standard uses girth, this cubage table for wood blocks or logs is based on diameter, to take account of the consistent and justified use of diameter in French-speaking tropical countries. Clear and precise instructions for using ...
