Testo completoThe sharp increase in agricultural yields in the past 150 years owes a lot to the improvement of plant varieties, which, to large extent, is the result of the research and development process. Whether the research and development effort undertaken by firms operating in this sector and institutions regulating research are socially optimal is an important question for public policies. This thesis aims to contribute to tackling this issue, and its main contribution is to endeavor to account for the impact of crop innovation on the environment. We address the question through three different perspectives: innovation per se, the research and development process, and the institutional framework available to research firms. We show that environmental externalities of research significantly modify social optima

Testo completoThe thesis explores the role of tinkering as a framework for analyzing the adaptation of agricultural equipment to promote the sustainability of agricultural systems. The initial results of surveys conducted with dealers and agricultural advisors highlight shortcomings such as commercial bias and terminological confusions. An additional study based on YouTube videos sheds lights on the importance of agricultural DIY, particularly focusing on soil and seed drills. Interviews with farmers reveal their growing interest in soil conservation agriculture as a response to climate change, as well as their tendency to customize their equipment, especially seed drills, to make them more suitable for new agricultural practices. The modularity of agricultural equipment emerges as a necessity to meet the evolving needs of farmers and promote more resilient and sustainable agriculture. Lastly, the interaction between technical advances in agronomy and equipment DIY is emphasized, underscoring the importance of technology innovation tailored to the practical needs of farmers for a more flexible and sustainable agriculture

Testo completoFrench agriculture, which perpetuated an after-war objective of established efficiency criteria, was guided by the search for a greater productivity. This direction, promoted by both the Common Agricultural Policy and the globalisation of the markets, was mostly driven by States with strong agricultural potentials, especially France playing a leading role. This evolution was guided by scientific and technology innovations, carried by three initial promoters: the public authorities, the agricultural sector and industrial groups. Scientific innovations, in an effort to protect the plants and improve the quality of vegetables, triggered a growing involvement of public authorities which faced alerts from environmental activists and increasing public opinion on the matter. The expansion of a national legislation has been followed up over the last twenty years by a growing European regulation. The latter aims at establishing a compromise between health and food safety as well as protecting the environment and industrial progress. It also questions the coherence of the existing legal framework for agricultural crops applied to the French territory, the current legislation on scientific innovations for plant agriculture and it's possible limits. This thesis deals with 'The French and European Law Facing Scientific Innovation for Plant Agriculture'

Testo completoBiofuel development supported by the international community expands since the early 2000s globally to reduce emissions of greenhouse gases, meet the energy concerns of industrial countries and reduce energy poverty in the countries of south. This strategy meets several controversies that address the socioeconomic impacts of biofuels and the most appropriate technological trajectories to the needs of developing countries in sub-Saharan Africa. The aim of the thesis is to understand the determinants of the process of technological innovation on the production of biofuels. The thesis raises two hypotheses for this. The first assumption structured by intersection between the theories of transition and systemic analysis of innovation based on institutional determinism of technological innovation process that structures the emergence of the biofuel sector. The second assumption is that the emergence and development of the bioenergy sector resulting conditions of micro-economic and territorial adoption of the production of energy crops. The test of these hypotheses is achieved by mobilizing an analytical reference in terms of innovation system in the case of the Jatropha sector in Burkina Faso. The results highlight the emergence of biofuels technologies in sub-Saharan Africa is related to institutional changes induced by the energy and environmental crises. These institutional changes enable favorable resources to the emergence and diffusion of technology on biofuels. In Burkina Faso, these changes are driven by European policies and those of sub-regional organizations such as UEMOA and ECOWAS. Econometric modeling allows complementary way to test the conditions of microeconomic adoption and implementation of technological innovations on biofuels. Structural factors of the farm (land capital, food situation, perception); the proximity of the actors of the sector; and institutional variables inherent in capacity building and skills appear structuring of these processes of adoption of Jatropha. This adoption also depends technological models that integrate a territorial perspective the production phases of the raw material, processing and use in a response mechanism to the priority needs of the development of Burkina Faso

Testo completoAgricultural research has an important role for the world population by considering it as a strategic area for providing knowledge and technological base for agricultural production. This sector generates outputs, outcomes with respective impacts to rural zones, supply chains, economy, society and environment. The agricultural research & innovation represents a key piece for reaching the United Nations sustainable development goals (SDG), especially to SDG 2 and 12 – to promote sustainable agricultural to eliminate hunger and improving nutrition, as well as to promote sustainable consumption and production, respectively. In order to check whether agricultural research organizations generate sustainable impacts, it is necessary to assess the impacts of their innovations. Funders, supreme auditing institutions, parliament, government, producers, supply chains, consumers and all society require transparency, efficacity, and effectivity of public organizations: they must highlight return of public investment as well as generate positive impact to the economy and society, and minimize negative impacts to the environment. Many public research organizations around the world have developed impact assessment processes. There is no flawed theories and practices approaches to impact assessment context. Therefore, this research seeks to fill gaps or to supplement the existing approaches. The main thesis objective is to summarize theoretical and practical studied approaches on impact assessment, including the experiences of four research organizations, and to develop a conceptual model of innovation impact assessment management system, especially applicable to agricultural research organizations. It adopts a methodology based on literature review, four cases of a comparative study of agricultural research organizations (Cirad and Inra from France, Embrapa from Brazil, and CSIRO from Australia), and benchmarking these experiences studied. The innovative contributions of this thesis are I. construction of a conceptual model of an impact assessment management system based on the open innovation process; II. the model of innovation impact assessment management system considers a cross-cut view of sustainability, integrating the environmental, social, political and economic dimensions; III. the innovation impact assessment system will be based on a unique managerial process that regards ex-ante and ex-post assessment stages according to its respective temporality; IV. the management of the innovation and impact assessment processes foresees the insertion of behavioral approaches such as concepts of holism, constructivism, transdisciplinarity and agile management practices as essential requirements for the effective engagement of the internal and external actors and the effectiveness of the evaluation process. This thesis has an original approach by bringing a research governance tool with an innovative focus on ex-ante and ex-post impact management, helping research and innovation organizations to become increasingly sustainable in their institutional missions, thus contributing to the achievement of the UN's sustainable development goals towards more productive and sustainable agriculture

Testo completoIn spite of measures aiming to reduce the environmental impact of agriculture, changes in farming practices remain modest while societal concerns continue to rise. The environmental mission assigned to agriculture is complex and subject to interpretation. The growing number of diverse stakeholders turning their attention to farming increases the demands placed on agriculture. In this context, the goal of this thesis is first, to understand how a diversity of agricultural and non-agricultural stakeholders involve themselves in transition processes towards more environmentally-soundagriculture and second, to understand the effect of their involvement on farmers practices. To achieve this, I relied on a pragmatic approach wich highlights "frictions", as well as "holdfasts" used by stakeholders and makes it possible to give a faithful account of their interpretations and experience of transition processes. Based on a socio-historical analysis and three case-studies from the Paris region, I characterized, first, the conditions of the emergence of movements promoting change in agriculture practices, second, the enrollment processes throught wich the issue of transition makes sense and, third, the changes in terms of both agricultural practices and forms of governance of those changes as well. The study shows that transition processes emerge as the result of adjustements between diverse stakeholders embedded in different communities. This analysis suggests the emergence of a "territoire-based contribution" model of change, where a diversity of stakeholders contributes by their discourse and actions to the ecologization of agriculture in their territoire
