Relatively intensive, high-yield farming systems often have lower environmental impacts per unit of product, according to a new paper. The paper used a new framework to measure both land use and major environmental externalities (greenhouse gas emissions, water use, and nitrogen, phosphorus and soil losses) for several different farming systems.

A recent paper uses data from three countries (Ghana, Mexico and Poland) to determine whether more carbon can be kept in above-ground stocks by land sparing (increasing farms yields to minimise the conversion of natural habitats to farmland) or land sharing (increasing carbon stocks on farms, at the cost of converting more natural habitat to farmland because of lower yields). Land sparing maintained the highest above-ground carbon stocks in all cases studied.

FCRN member Ben Phalan of the Universidade Federal da Bahia has written a paper discussing the strengths and limitations of the land sparing-sharing framework, which aims to allocate land use and production intensity so as to maximise the value of land for wildlife while still producing enough food for people. He notes that most studies show that wildlife would be favoured by producing food intensely on as little land as possible, and addresses some common criticisms of the model.

Intensifying agricultural production can make farmland less valuable for wildlife, says a new paper, but optimising land use (by intensifying agriculture in areas where it will cause the least biodiversity loss) can reduce the projected biodiversity loss by up to 88%. The winners and losers of this strategy depend on whether land use is optimised globally or nationally.

This paper by researchers from the USA, UK and Mexico examines the biodiversity conservation and carbon storage implications of a number of land-use scenarios related to cattle ranching in Yucatán, Mexico.

In this article a group of American researchers provide commentary on how sustainable applications of integrated agricultural systems (IAS) can be designed to enhance all ecosystem services, without compromising the land’s resilience. The authors describe IAS as an interactive and synergistic resource transfer between multiple agricultural enterprises over space and/or time.

This paper in Biological Conservation argues that the role of pesticides in driving biodiversity loss deserves renewed emphasis, quantification and amelioration. The authors present their views on how conservationists should support integrated approaches, for sustainable agriculture and rural development planning, that simultaneously address food security, pesticide use and biodiversity conservation.

In the latest in a series of articles seeking to shake up the conversation about food production and its trade-offs (see for example our previous summary of Elena Bennett’s Nature commentary, and the subsequent FCRN discussion forum), this opinion piece seeks to shift the focus of the discourse away from food production as the goal of agriculture, and towards food security, incorporating biodiversity outcomes.

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.
