This review assesses the performance of organic cropping systems as an approach to sustainable agriculture, and seeks to identify the contextual considerations (such as type of cropping system) that may affect this performance. The scope of the review is constrained to the level of the farming system (i.e. excludes considerations of other components of the food system, such as packaging or transport). In order to provide an unbiased assessment of organic farming as a means of sustainable agriculture, rather than approaching the question from the usual “What does organic farming do well/badly?” angle, the authors ask “What constitutes successful sustainable agriculture?” then measure organic farming against this yardstick.
A new study submitted to us by an FCRN member, highlights a final report from a four year, multi-disciplinary research project conducted by the Institute for Sustainable Food Systems at Kwantlen Polytechnic University (located in Richmond, BC, Canada).
This book considers the main links between global conservation of the environment and food production.
This newly revised edition by Cambridge researchers sets out to help those interested in evidence-based conservation with summaries of relevant topics.
Opponents in an academic discussion on the relevance and the validity of the ‘Ecological Footprint approach’ have come together to write an article in which they challenge each other’s views.
There is increasing evidence that human demands on natural systems are accelerating and could affect the stability and services provided by these systems. This paper aims to aid understanding of the temporal and spatial variability of human pressures on natural systems, which provides a foundation for environmental damage mitigation. Recent advances in remote sensing have allowed great development in mapping of human pressures, particularly in forested areas. Other pressures, such as roads and pasture lands, have by comparison been overlooked.
In Sweden two of the largest supermarkets in the country have launched campaigns aimed at creating increased consumer awareness around the environmental impact of meat, encouraging consumers to lower their intake of meat and promoting plant-based alternatives.
In this modelling study, the authors examine potential trade-offs between sufficient food provisioning in the future and sustaining biodiversity. On the one hand they find that cropland expansion increases food security, particularly in areas which are currently struggling with access to safe and nutritious food.
In this analysis presented in the journal Nature, four conservation scientists warn against the current trend of over-reporting on climate change’s impacts on biodiversity. Instead, they find that by far the biggest drivers of biodiversity loss are overexploitation (the harvesting of species from the wild at rates that cannot be compensated for by reproduction or regrowth) and agriculture.
Voluntary programs represent a widely accepted policy tool for biodiversity conservation on private land and are often market-based (monetary) rather than appealing to values and morals. A growing body of evidence suggests that market-based approaches to conservation, albeit effective and relevant in many cases, are not always sustainable in the long term.
This paper argues that the failure of protected areas to guard biodiversity partly reflects a lack of science available. The paper offers strategic guidance on the types of science needed to be conducted so protected areas can be placed and managed in ways that support the overall goal to avert biodiversity loss.
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.
Global Forest Coalition and Brighter Green have just released a new report, “Meat from a Landscape Under Threat: Testimonies of the Impacts of Unsustainable Livestock and Soybean Production in Paraguay.”
This study in BioScience compares coverage of biodiversity and climate change in newspapers, scientific articles, and research funding decisions, and finds that climate change eclipsed biodiversity loss as a priority in the mid-2000s.
