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.
Currently, land-sparing and land-sharing are two of the most prominent schools of thought concerning the relationship between agricultural production and biodiversity. Advocates of the former approach believe that the best solution to maximising food production sustainably is to promote high-yielding intensive agriculture on as small a land footprint as possible, ‘sparing’ more physical space for biodiversity and conservation. Advocates of the latter approach, on the other hand, believe that agriculture should be less intensive and that the (larger amount of) land used for this extensive agriculture should be farmed in a wildlife-friendly way; i.e. ‘shared’ with biodiversity.
Dr. Bennett, however, argues that the reason no agreement or conclusion has ever been reached in this debate is that it presents a false choice between two extreme ‘solutions,’ neither of which address the complexity of food security beyond food supply, nor of ecosystem services beyond biodiversity. Instead, Dr. Bennett poses some new, more nuanced, questions to ask, which amount to: ‘What ecosystem services are important and which can we promote in the landscape to best improve human well-being, now and in the future?’. Although lacking detailed actionable suggestions, this article provides a much-needed critique of the overly reductionist ‘food vs. biodiversity’ debate that pervades agricultural and environmental thought.
The land sharing/sparing debate has stagnated. Finding a way forward requires that we ask new questions and, crucially, focus on human well-being and ecosystem services.
