Outils et méthodes pour une politique territoriale de gestion raisonnée des pratiques agricoles : cas d’application dans la région de la Béqaa au Liban.

Abstract : For many countries, food security is the biggest challenge facing agriculture, while ensuring environmental sustainability. Sustainable intensification of production and preventing crop losses are key element to increase production and ensure their consistency, massive inputs (fertilizers, pesticides) use is most often the easiest and the safe solution in the short term. These intensification practices resulting sometimes in increasing excessive consumption of fertilizers and pesticides have a negative impact in both environment and human health, which today pose the problem of the sustainability of these production methods. Ensuring food security through process intensification and environmental sustainability seem to be in opposition. The impact on the environment and human health from the intensification of agricultural practices with the increase in using chemicals has carry civil society and governments to query the sustainability of this development system and to question the scientific community to provide other types of production for sustainable development. How to build sustainable systems of agricultural production in the territories, while responding to the objectives of increased production to ensure an acceptable level of food security. This question as part of climate change today has become central to policy makers. Agriculture is associated to the concept of territory, environmental sustainability to a collective problem; modify the parameters for the formulation of public policy actions. We must now build integrated management approaches and collective agriculture in these territories, taking into consideration the local stakeholders, the potentialities and the specifications of the physical environment. To build a collective project, it is crucial to understand the representations that users and stakeholders in the management and the ecosystem uses should be done in dynamics and interactions between rules of practice and behavior of local actors. What tools and methods must implement policy-makers in the territories to meet these goals? The framework is at the interface of different scientific fields; agronomy, geography and economics. A model of the operation planning as an instrument of support for the dialogue seems to be appropriate for such approach; possible to simulate different alternatives and allow viewpoints. The first part of the thesis will focus on a literature review of existing instruments and methods in this area, particularly in terms of indicators of characterization and alternative solutions in terms of production. The choice in terms of generic method is oriented on elaborating of tools in spatially, collective and interactive simulation. The goal is to build a method for developing an agricultural strategic planning to allow the basis of a territorial public policy. The field of application will be the Bekaa region in Lebanon, which is an intensive farming area in Lebanon, and contributing very significantly to agricultural production in Lebanon.
