Summary

At the interface between agronomy and environmental assessment, the stake of this thesis is to better account for the soil-climate-and agricultural management in the Life Cycle Assessment of cropping systems. The objective is to provide an inventory considering water as a resource but also a vector of solutes such as nitrogen and salts, with the underlying purpose to feed the actual and futures methods assessing water and salinization impacts in LCA.

Summary

Context

The PhD began with a comparison of two environmental assessment approaches: a “site” approach (Environmental Impact Assessment, EIA) and a “product” approach (Life Cycle Assessment, LCA). Their similarities and differences were discussed, in order to see how they could complement and enrich each other.

Objectives

Following this analysis, potential general research issues were formulated for extending one and / or the other of these two approaches. One of these challenges, regarded as a major societal issue, consists in defining or improving new locally-relevant impact categories, such as the water use or the land use. In this context, the question of the impact of land use on biodiversity was chosen.

Based on literature review of land-use impacts in LCA, the main research needs identified were: (i) take into account not only the destruction of habitat, but also habitat fragmentation and (ii) define more comprehensive indicators of the state of biodiversity (various components of biodiversity).

Thus, habitat fragmentation, considered as a relevant lever for improving the impact of land use on biodiversity, was chosen as research question.

The study of habitat fragmentation in the ecological literature should then be used to make the link with LCA in order to define the causal chain associated with this human pressure.

The main objective of the PhD is first to develop a conceptual framework for the integration of fragmentation in LCA. Secondly, and depending on the remaining time, operational implementation of this framework could be proposed (application of the model on a global scale).

Application

This research question is at the interface of EIA and LCA, as it could not only improve the current LCA methods but also better assess the offset measures in EIA.

Summary

The main challenge of this thesis is to further develop life cycle impact assessment (LCIA) methods on eutrophication and freshwater ecotoxicity categories with a differentiation in emissions with respect to their intensity and temporal distribution. Indeed, current impact characterization models do not include temporal dynamics in the emission of a pollutant between its source and its target. The proposed approach will combine this temporal differentiation with a spatial differentiation of emission sources, in order to discriminate between impacts originating from an incidental, point-source emission (eg WWTP overflow) and impacts arising from a diffuse or non-point emission (eg daily expected release from a WWTP or nutrient leaching to river systems from agricultural lands). The selected application is the differentiation of impacts associated with daily discharge of WWTP compared to point source discharges over time eg in relation to an overflow due to weir storm.

Water footprint and impacts LCA of the consumption of water: development of indicators of water quality
Charlotte PRADINAUD, Irstea – Ecole des mines d’Alès PhD student

Summary

The objective of the PhD is to develop a relevant water quality indicator according to the potential use, while identifying and eliminating the potential problems of double counting. This should be realized on the basis of the water footprint indicators existing, but also of local quality indicators of the water. It will involve the analyzing of the need and the possibilities of adapting the average indicator at a country scale to bigger spatial scales in order to better answer to the regional / local specificities. An additional prospect will be to integrate into the water quality indicator the impacts due to micropollutants and emergent contaminants. The work will begin with a detailed analysis of the existing models of waterfootprint and water use in LCA. Secondly, the parameters having a significant influence on the global variability of the indicator will be identified and an average global indicator will be developed. Finally, the spatial variability of the indicator will be studied by analyzing the effects of the consideration of the local conditions on the characteristics of the average indicator.

The approach will be applied to one or several examples of activities having strong environmental pressures on the quality or the local resource in water (ex: technologies of water supply, territorial management of the water resource, etc.)

Water footprint and Life Cycle Assessment – Development of a methodological framework for the regionalized consideration of different water sources in LCA
Susana LEAO, Irstea – Ecole des mines d’Alès PhD student

Summary

Context

The water used for human activities may come from different sources. It may be of conventional (river water or groundwater) or unconventional (water reuse, desalinated water, etc.) origin and may be suitable for different uses directly related to its quality. In Life Cycle Assessment (LCA), current methods used for life cycle inventory (LCI) can differentiate the source of water used from the conventional sources of water, which is not the case for unconventional sources. Nevertheless, they are increasingly used, especially in arid countries where water is a scarce resource, and the more so in a context of climate change where the availability of conventional water resources decreases. In addition, the availability of water varies in each country / watershed. However, current practice in LCA does not sufficiently take into account the geographical differentiation. To use methods for assessing environmental impacts specific to each water source, the stage of the life cycle inventory should allow determining the type of water source used depending on the type of use.

Objectives

The main objective of the thesis is to include information on the source and the quality of the water used in the life cycle inventory phase depending on the type of human activities (agricultural, domestic, or industrial use, etc.) and for each region (country / watershed) in the world. In analogy with the electric mix in LCA, the objective is to develop regionalized water supply mix depending on the type of water use.

The influence of socio-economic and climatic factors on the regional availability of future water resources will also be a focus of the thesis work with the aim to develop several scenarios on the availability of water resources and the ability to adapt in different regions of the world.

The developed approach will be applied to one or more examples of activities with strong environmental pressures on the quality and availability of local water resources (e.g. water supply technologies, territorial management of water resources, etc.).
