Biodiversity and agronomy - Introduction

/ Canal-u.fr

Voir le résumé
The biodiversity plays a key role in the development and the upholding of the agrarian practices all over the world. This biodiversity is related to the grown species and varieties, but also to the ecosystems where those farmings are established, starting with the soil. The recent evolution of those practices shows a considerable decrease of the structure and of the functioning of this biodiversity. In the short and medium terms, this is a threat for the food production capacities. In order to ensure a sustainable agriculture, Etienne Hainzelin points out the necessity to develop agrarian practices, which are more intense from an ecological point of view.

Voir le résumé
In this third part, you will discover the biodiversity of the terrestrial and continental aquatic environments. Those environments are extremely diversified and are subjected to very specific dynamics, like intermittent rivers or ecological successions of the forest environments. Some of those environments present important physicochemical variations, like the rivers, from the spring to the estuary. The biodiversity is very rich in those environments, and several preservation prospects are presented. Mot(s) clés libre(s) : biodiversity, forest, river
