Showing results for: Land footprint
This paper compares stylised, hypothetical dietary scenarios to assess the potential for reducing agricultural land requirements. It suggests that a combination of smaller shifts in consumer diet behaviour – such as reducing beef consumption by replacing with chicken, introducing insects into mainstream diets and reducing consumer waste – could reduce agricultural land requirements.
The authors of this paper compare the impact of intensification in the beef and dairy sectors via two pathways; either intensification within a system (e.g. a mixed crop-livestock system) or through transitioning to another more productive system (from pasture to mixed crop-livestock production) and assesses the mitigation potential that could arise. It reviews the impacts of these forms of intensification on both GHG emissions, land occupation and land use change (LUC), the last of which has often been excluded in other similar analyses.
A new study submitted to us by an FCRN member discusses the virtual land footprint associated with regional supply capacities.
With global trade, UK consumption patterns are displacing cropland use to other countries. This paper by FCRN members Henri de Ruiter, Jennie Macdiarmid and Pete Smith looks at the environmental consequences of competition for global agricultural land and specifically at the total land footprint associated with the total livestock product supply in the UK.
This article by T.C. Ponsioen of Wageningen University, and H.M.G. van der Werf of INRA, discusses the major sources of inconsistency in life cycle assessment (LCA) analyses of food and drink, and makes recommendations to address these inconsistencies. The article begins by describing the many attempts that have been made to standardise (or ‘harmonise’) environmental footprints of food and drink, and identifies five main areas which lack consensus.
Over the past half-century, the paradigm for agricultural development has been to maximize yields through intensifying production, especially for cereal crops. But achieving food security and building a healthy, resilient global food supply is about more than just the quantity of calories provided. New metrics of success and methods of evaluation are needed in order to measure progress towards meeting the world’s nutritional needs within environmental limits.
This paper by FCRN member Lukasz Aleksandrowicz and colleagues consolidates current evidence on the environmental impacts of dietary change, finding environmental benefits are possible from shifting typical Western diets to a variety of alternative dietary patterns. The results also highlight that there is still complexity in defining environmentally sustainable diets, though moderate reductions in meat consumption (particularly ruminant meat) replaced by plant-based foods, seem to reliably reduce greenhouse gas (GHG) emissions, land use, and water use, as well as improve health.
The EU uses more than its fair share of global land; in 2010 the amount of land needed to satisfy our consumption of agricultural goods and services was 43% greater than the land available within its boundaries. This report stresses the responsibility that the EU has to measure, monitor and reduce its global land footprint.
The authors of this paper have tried to develop a framework to apply the concept of planetary boundaries to national level decision making and to discuss what a country’s ‘fair share’ of Earth’s safe operating space could be.
Future demand for food and for land is set to grow. A key question is therefore: how can we most productively use land for food, in order balance the multiple competing demands for the ecosystem services it provides? One way this has been investigated previously is by looking at crop yields and how to increase them. Another way, focussing instead on the consumption side, has looked at the metric of dietary land footprint.
Entering into the sustainable intensification debate, Johan Rockström from the Stockholm Resilience Centre and colleagues propose that a paradigm for sustainable intensification can be defined and translated into an quantitative, operational framework for agricultural development.
This EU brief looks at a recent study assessing the social environmental impacts of agricultural imports to EU from other, often less developed countries. The EU has thus picked up on an important study assessing Europen diets' contribution to excessive land-use in countries outside of the European Union. FCRN has previously highlighted this study (Balancing virtual land imports by a shift in the diet. Using a land balance approach to assess the sustainability of food consumption).
A new study from International Institute for Applied Systems Analysis IIAS considers whether it is possible to reduce greenhouse gas (GHG) emissions from agriculture by producing more food on less land. It specifically focuses on the effects of crop yield and livestock feed efficiency scenarios on GHG emissions from agriculture and land use change in developing countries.
