Texto completoThe current climatic and environmental upheavals deeply impact our society and ecosystems. Food production and consumption play an essential role in these disruptions. The globalized food system, characterized by mass production and consumption and a disconnect between producers and consumers, places significant pressure on territories and their resources. To address this, the reterritorialization of food is emerging as a promising solution for a more sustainable food system. France is at the forefront of this initiative, with the recent development of Territorial Food Projects (Projets Alimentaires Territoriaux, PAT) led by local authorities. These projects aim to promote a local and sustainable food economy while supporting short supply chains. However, despite their potential, the environmental impacts of these initiatives remain understudied. Most current studies compare short and long food supply chains, focusing on transportation-related impacts. Consequently, they do not consider the systemic benefits associated with the development of more sustainable practices within local food systems. To respond to this issue, this thesis adapts the Territorial Life Cycle Assessment (TLCA) methodology to assess local food systems from a systemic and environmental perspective. This adapted methodology is applied to two diverse territories in France and their local food systems: the municipality of Mouans-Sartoux and the Finistere department. Both territories are pioneers in implementing food territorial projects (PAT). The environmental assessment of the two local food systems reveals the extent of both direct and indirect impacts, notably related to imported products and agricultural inputs. The results demonstrate that transportation played a minor role in these impacts. Both local systems heavily depend on imports to feed their inhabitants. The short food supply chains, and consequently their impact, remain limited. The assessment of the impact of the Mouans-Sartoux local food policies demonstrates positive effects since their implementation. An estimated reduction in environmental impact equals approximately 20 % of the entire local food system's impact, particularly in terms of climate change and land use. In Finistere, the prospective analysis highlights the potential benefits of local strategies, particularly in connection with the promotion of agroecological practices. In conclusion, this interdisciplinary work confirms the relevance of life cycle assessment methodologies for local planning and assessment. It equally reveals the potential of local food policies to contribute to the ecological transition

Texto completoFor the sake of the sustainable development as a measure against global environmental change, urban consumption needs to be studied through the processes that underlie production and assessed in terms of resource use and pollutant emissions into the environment. This PhD thesis devotes to understand the mechanisms in supplying meat and milk to Paris over two hundred years and measure the land requirements, water withdrawals and nitrogen flows between agrosystems and the environment to supply each product in the early 19th, 20th and 21st centuries. We used agricultural and transport statistics from French and international data sources to locate the Paris hinterland at each date, quantify the urban food supply as a proportion of the regional potential food production, precisely model the diets of the livestock according to the animal productivity and the feed availability in the regional and global markets at the dawn of each century, compute the nitrogen, energy and feed conversion efficiencies in the meat and milk production and, finally, assess both the size and the geographic pattern of the Paris acreage (spatial imprint) and of the nitrogen and water flows in support of the production. The water imprint is used to account for the water withdrawals (irrigation and rainwater) in terms of volume and use intensity. The N imprint measures on the one hand the total amount of reactive nitrogen entering the agrosystems and the partitioning of these inputs between the food production and the environmental losses. The latter are referred to as “the depth” of the urban imprint which provides a measurement of the indirect contribution of urban areas to the alteration of the N cycle. When expressed on a “per capita” basis (kg N/cap) the depth of the imprint shows the emissions of reactive nitrogen to supply the diet of one person as opposed to the direct individual N discharge in urban wastewater. When expressed on a “per hectare” basis, it shows the intensity of the upstream urban N emissions and can be used as a tool for assessing urban sustainability beyond the city limits. Since the early 19th century, the land requirements for the “per capita” meat and milk consumption in Paris (equaling about 2 kg N/cap/year in both the early 19th and the early 21st centuries) reduced six-fold – with about 30 % of the reduction relating to the doubling of the nutrient conversion efficiencies in the secondary production – but the water use intensity and the “per hectare” depth of the imprint respectively doubled and quadrupled. We estimate that currently, about 45 % of the N losses - meaning 5.1 kg N/per/year or 60 kg N/ha – stem from abandoned manure. As the beef, pork and fresh milk imports to Paris currently account for about 25 % of the protein intake of a Parisian and given that animal production is a priori more wasteful that primary production, we estimate that the “per capita” emissions of N for providing the whole diet equal over 7 times the urban N discharges, meaning that a city's wastewater treatment plants handle less than 15 % of the total (direct and indirect) food related N emissions of the citizens

Texto completoThis thesis addresses the research question of how demand requirements for eco-responsible and local products may impact the food supply distribution configuration. In other words, how to configure urban food systems to satisfy a demand for eco-responsible food products. Therefore, the purpose of this research is to explore how to estimate the relationship between a demand for eco-responsible and food distribution configuration considering economic and environmental issues.The thesis is a compilation of three phases:• Eco-responsible food demand: It seeks to identify the product's environmental quality criteria that impact product demand and how these demand's characteristics can be used to describe the requirements of logistic schemes for sustainable distribution.• Food supply chain configuration: Considering these new requirements, this phase aims to describe the food supply chain strategies that achieve a sustainable food distribution addressed in the literature, and to analyse how these strategies identified impact logistic decisions in the supply chain.• Food supply chain assessment: It attempts to analyse the estimation of economic and environmental indicators that may represent the impacts generated in the configuration of the different food distribution schemes proposed.The results highlight a framework proposal, aiming to understand how changes in a current food distribution system can be identified and quantified (in a logic of before-after scenario assessment). This framework includes: (i) Logistic decisions to be considered in the distribution system at strategic and tactical level. (ii) Food system characterization to define an initial situation (stakeholders, demand and supply characterization), and the demand and supply estimation; (iii) Scenario construction to analyse scenarios to be tested; and (iv) Scenario assessment to identify and assess economic and environmental impacts of the food distribution system, including tests and expert feedback to validate the scenarios proposed

Texto completoGrowing environmental preoccupations and a rapid evolution in food consumption tendancies have led us to analyse the strict interdependance between farming and food production with regards to the natural environment. Environmentaly friendly food products are the result of modifications in production practices, that we consider to be a technological change within the farm, and thus add a social fonction to the food function, making these products highly specific. The major stake in developing these products will be to suceed in showing their economic and commercial value. From varius examples of organic or integrated products, we have made an attempt to list the quality conditions requiered for these products. These conditions are established through coordination between agents and quality agreements based on trust. But new technological changes in environmentally friendly farming practices are going to make production structures evolve because they necessitate individual and collective learning. This evolution can lead to new forms of business organizations in order to maintain the specificity of theses products to the end consumer. Observing varius examples allow us to suggest some ways to develop these products

Texto completoRice has become a primary consumed product in Benin. Studies have revealed it will become the most consumed cereal in west Africa within the next decades. Despite the resources Benin possesses favouring rice culture and the government measures to promote it, the household supply remains unsatisfactory when compared to the objective set by the country to reach food sovereignty. The present essay analyses the government policies in order to reach a sustainable food sovereignty through rice culture. In depth, exploratory surveys have been conducted among the rice farmers. Qualitative and quantitative data was collected through structured questionnaires and guided interviews revealing the comparative advantage local rice has over imported one. Efforts have yet to be made in order for Malanville rice famers to reduce their production costs and become more competitive. Education level, access to loans, rice farmers experience as well as their social status are the key factors influencing the implementation of new technologies allowing an increase of productivity. Rice production and food sovereignty should be attained by implementing simultaneously income support policies, funded fertilizers, climate-smart culture and ploughing by oxen
