Beschreibung
The originality of this book is to review and characterize the current body of scientific publications that describe the complete causal sequence from reorganization of agricultural production to land use changes (LUC) and the resulting environmental impacts.
Concerns have been raised recently about the consequences of LUC linked to the expansion of primary production for bioenergy, notably in terms of the greenhouse gas impacts. Such concerns have prompted a sharp increase in the number of scientific publications on this topic over the past ten years. However, scientific research on LUC tends to be highly segmented between that focused on LUC drivers and the body of work examining LUC impacts.
In fact, in order to account for LUC impacts /within /when assessing the environmental footprint of biomass production, we need to be able to link reorganization in biomass production to changes in the use and management of soils, and then determine the impacts of those LUC onthe environment. Surprisingly, no systematic literature review encompassing this full causal sequence, “drivers – LUC – environmental impacts” have been carried out so far.
The present book chapters examines both the range of territorial reorganizations leading to LUC and the range of associated environmental impacts considered in the literature, including GHG emissions, atmospheric pollution, biodiversity impacts, water resources, and soil quality.
The analysis consisted of four principal steps: i) identification of research articles using a bibliographic search process; ii) description of these articles’ main characteristics; iii) textual analysis of the articles and identification of thematic sub-groups; iv) closer examination of a subset of the sub-group pertaining to non-food biomass production based on a detailed template and a thorough analysis of the results. This is the first time this set of approaches was combined to assess the environmental impact of LUC, andspecifically those related to non-food biomass production.The originality of this book is to review and characterize the current body of scientific publications that describe the complete causal sequence from reorganization of agricultural production to land use changes (LUC) and the resulting environmental impacts. The chapters examine both the range of territorial reorganizations leading to LUC and the range of associated environmental impacts considered in the literature, including GHG emissions, atmospheric pollution, biodiversity impacts, water resources, and soil quality.
Textual analysis is a powerful tool for mapping a large set of article on a topic (in this case LUC drivers and environmental impacts) and have a quick overview of its structure and content The cross analysis of all drivers and all environmental impacts show that impact valuation depends on the methodology used: economic models appear to be more conservative than other methods Evidence mapping methodology was used to summarize the main characteristics of the set of 241 studies in a graphical user-friendly format. It highlights major knowledge gaps and future research needs on the land-use-mediated implications of biomass production
