The Matière à débattre et décider collection is intended for decision makers (communities, businesses, associations and public authorities), project managers and any citizen seeking to form an opinion in total liberty on topical, sometimes provocative subjects. It includes books designed to provide them with elements for debate and reflection. Collective, predictive or synthetic expert accounts, these works are written by specialists, in clear language with concrete, quantified and frequently international examples. This coolection icludes the publication of the ancient coolection Expertises collectives.
The recycling of organic waste can be considered an agro-ecological practice which enhances soil fertility, reduces environmental impacts and promotes a circular economy. This book gives readers insight into the bio-geochemical processes involved in recycling organic waste and the products derived therefrom. It offers solutions for various social, economic and cultural contexts, North and South.
This work presents an overview of resources and the use of fertilisers derived from waste in France, and provides key insights into how they can replace mineral fertilisers. It focuses on the agronomic, environmental and socio-economic impact of waste expansion and highlights how difficult it is to quantitatively assess the advantages and disadvantages of using these materials.
Severe acute respiratory syndrome (SARS), avian flu, Ebola virus or Middle East respiratory syndrome coronavirus (MERS-CoV) are increasingly attracting the attention of scientists, risk managers, the media and the general public. Specialists analyse the ecological, social, institutional and political dynamics associated with emerging infectious diseases. They show the challenges but also the opportunities taken up by the players faced with these diseases.
Agriculture in France accounts for approximately 20% of all greenhouse gas emissions. This book suggests ten actions or agricultural practices to reduce them without substantial change to production systems nor a significant reduction in production. An estimated mitigation potential for each one in tonnes CO2 equivalent avoided and the associated costs or savings in euros are given for 2030.
The link between green tides, nitrogen flows and agriculture has been established, but which agroecological transitions suit the region and how do we embark on them with the stakeholders in question? To respond, the players rely on the results of the research programme ACASSYA "Support agroecological changes in livestock systems in coastal catchment areas".
In a context where the resources continue to simplify and where the rotations are increasingly short, crop diversification seems essential to reduce the use of agricultural inputs, especially pesticides. This work analyses the main obstacles to crop diversification at the level of the agricultural industries and farms. It suggests ways of shaking up highly-specialised productive schemes and creating new ones.
This work makes updated scientific knowledge of nitrogen flows on livestock farms and their fate available to policymakers and public and private players. It also identifies technological, organisational, structural or territorial options to reduce the pressures of nitrogen emissions from farms on the environment.
So-called "herbicide-tolerant" varieties of sunflower and oilseed rape have been introduced in France since 2009. Intended to make weedkilling easy, these varieties resist a given herbicide, meaning theoretically that the herbicide can be applied without risk to the crop. Cultivating such varieties has sparked social protest, resulting in herbicide-tolerant sunflower crops being denounced and pulled up as "hidden GMO". In this context, the Ministries of Agriculture and the Environment have requested Inra and CNRS to report on available knowledge on all impacts of cultivating these varieties.
The French equine sector, that has enjoyed steady growth for some thirty years, is currently weakened by international competition, changes in regulations and reduced State support. This book traces the major changes in the sector and explores future possibilities. It sheds original light to help the institutional and economic players in the sector to build their future.
Soil fertility is at the crossroads of the challenges of food security, environmental protection and economic profitability of the agricultural activity. This book presents the results of a long-term reflection on the context of fertilisation in the next five to ten years. It defines the needs in terms of methods and tools for managing biogeochemical cycles and integrating fertilisation into agriculture.
