Showing results for: Land-sparing vs. land-sharing

24 January 2017

This newly revised edition by Cambridge researchers sets out to help those interested in evidence-based conservation with summaries of relevant topics.

In this Nature Comment article, Elena Bennett of the McGill School of Environment and the Department of Natural Resource Sciences, Québec, argues against the underlying premise of the ‘land-sparing’ vs ‘land-sharing’ debate that has dominated the agriculture-environment discourse for decades, and advocates a new and more holistic approach that focuses on maximising human well-being.

This paper makes an important methodological contribution to the highly disputed debate about whether the net effect of agricultural intensification on biodiversity is positive or negative. What is already known is that there is clear relationship between increased agricultural intensification and decreased biodiversity on the land that has been intensified.

An academic debate on the controversial possibility of decreasing greenhouse gas emissions via increased beef production in the Brazilian Cerrado finds a new set of commentators, who have responded to an original paper by de Oliveira Silva et al. earlier in 2016 in the same journal, Nature Climate Change.

Initiated in 1999, the Grain-for-Green Program was set up primarily to reduce soil erosion and uses cash payments to incentivise people to replant trees on sloped crop and scrubland. This study examines the effects on bird and bee species in the scheme across the country. It finds that the program has not greatly benefited birds and bees due to the common practice of monoculture tree planting.

This editorial article focuses on an aspect of agricultural food loss and waste, not often considered: the effects that a reduction in food loss and waste at the production stage, might have on the species that have become reliant on food waste.

The need to make the best use of agricultural land in the face of growing future demand has made sustainable intensification an important area of food systems research. Previous research which focused on this topic, looked at the spatial distribution of the intensity of agricultural production and how this has changed, but according to the authors, did not provide sufficient insight into the drivers of intensification patterns, especially at subnational scales.

The iPES food panel (International Panel of Experts on Sustainable Food Systems), has published a report reviewing the latest evidence on benefits and challenges with different production models, specifically looking at the industrial agriculture and agroecological farming systems. It argues that there are eight key reasons why industrial agriculture is locked in place despite its negative impacts; and it maps out a series of steps to break these cycles and shift towards expanding agroecological farming.

This paper in Science discusses the potential of yield increase incentives as a way of convincing farmers to save land to protect biodiversity rather than increasing farmland.   The increase of agricultural land is one of the leading causes of biodiversity loss and greenhouse gas emissions in tropical countries. This paper argues that increasing yields on existing agricultural land can provide farmers with the incentive to spare land for wildlife and nature.

This commentary published in Science Letters, discusses new data recently released by FAO’s statistical division, and makes the case that the current large-scale reversion in pasture area is opening up a potential conservation opportunity. Author and FCRN member Joseph Poore argues that as grazing of land has become more intensive globally, we are seeing ruminant outputs increasing while large agricultural areas are being abandoned, and he argues that this offers a new opportunity for land-sparing conservation.

In this paper, researchers from a number of UK and US research institutions explore the potential for land sparing as a greenhouse gas (GHG) offsetting strategy – that is, by increasing crop and livestock yields so as to enable agricultural land to be freed up and used for habitat restoration (for example) an enable carbon sequestration.

New research from Cambridge University finds that providing farmers and farmer industries with financial incentives to mitigate agriculture’s impact on the environment positively effects greenhouse gas reduction and increased biodiversity at the aggregate level.

The study analysed investment in two key types of agri-environment schemes: measures to spare land for conservation, and measures (such as taxation) intended to limit fertiliser use. The research team plotted this against national trends for farmland bird populations and emissions from synthetic fertiliser across the US, Canada, Australia and Europe.
