According to this study of farmland birds in Finland, bird abundance is positively correlated with the nearby presence of organic animal farms, as well as the percentage of nearby field cover and the presence of natural grasslands.
Following consultation with fishers and marine conservation experts, the UK government has created new Marine Conservation Zones around the English coast, taking the UK’s total protected areas of ocean to over twice the size of England. However, some critics question whether the protected areas are actually beneficial to wildlife.
This report from UK charity Rewilding Britain argues that rewilding peatlands, heathland, native woodlands, saltmarshes, wetlands and coastal waters in the UK could sequester carbon and also produce other benefits such as flood mitigation, enhanced biodiversity and water quality improvement.
Agriculture is one of the leading drivers behind the loss of species and ecosystems, warns the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). An estimated one million animal and plant species (one in eight) are threatened with extinction. Species losses are happening tens or hundreds of times more rapidly today than over the last 10 million years, with the rate accelerating.
This report from the Animal Law and Policy Programme at Harvard Law School estimates the carbon sequestration potential of converting UK land currently used for animal agriculture into native forest. The remaining cropland is enough to provide more than the recommended calories and protein for all UK residents, according to the authors.
This paper reviews studies where changes in both productivity and species richness have been tracked at the same location, following changes in the intensity of land use. On average, intensifying land use leads to a 20% gain in output and a 9% decrease in species richness, but there is considerable variation between different contexts.
Schools strike climate activist Greta Thunberg, along with several scientists, authors and campaigners, has called for “natural climate solutions” to tackle climate change and biodiversity loss simultaneously.
This paper shows that pollinator services in agricultural landscapes that have been highly altered from their natural state are lower than would be predicted from a simple count of pollinator species. The paper bases its estimates on a study of the evolutionary relationships between pollinators and extensive surveys of pollinators.
This report by international non-profit Forum for the Future outlines some key trends in sustainability that the authors expect will be important over the next decade. The report also aims to equip decision-makers with a greater ability to influence systems at the scale necessary to tackle global challenges.
This paper analyses how different agriculture and forestry activities affect biodiversity and carbon sequestration. In 2011, the top driver of losses to bird species richness was cattle production, while the greatest driver of losses to net carbon sequestration (relative to sequestration if natural vegetation were allowed to grow) was forestry.
FCRN member Peter Stevenson of Compassion in World Farming has produced a policy briefing for the Fourth Session of the UN Environment Assembly, arguing that industrial livestock production has a detrimental impact on soils, water, biodiversity and food security and also undermines small-scale livestock farmers.
This report from the FAO reviews the state of ‘biodiversity for food and agriculture’, i.e. any biodiversity that contributes in some way to food production. It finds that 26% of livestock breeds are at risk of extinction. Crop diversity is declining, with only 9 crop species accounting for 66% of crop production. One third of fish stocks are overfished, and a further 60% are being fished at their maximum sustainable capacity.
Over 40% of insect species are at risk of extinction over the next few decades and 75% to 98% of insect biomass has already been lost, according to this review of the current state of knowledge about insect declines, with habitat loss through conversion to intensive agriculture being the main driver. Agro-chemical pollutants, invasive species and climate change are also driving insect declines.
According to this paper, 23% of deforestation in Indonesia between 2001 and 2016 was caused by palm oil plantations, 20% by conversion of forests to grasslands or shrublands (including conversion caused by fire), 15% by small-scale agriculture, 14% by timber plantations, and the remainder due to other causes including logging roads, mining and fish ponds.
This book, edited by Pasquale Ferranti, Elliot Berry and Anderson Jock, offers readers a ‘one-stop’ resource on food security and sustainability. It has been written by both academics and practitioners.
This feature in the Guardian explores the reasons for the rapid growth of the anti-plastic movement. It also describes historical lobbying campaigns that painted plastic packaging as being the responsibility of the consumer rather than manufacturers, and outlines some of the issues associated with recycling plastic (in comparison to recycling, say, glass or metals).
This book, by David Lindenmayer, Damian Michael, Mason Crane, Daniel Florance and Emma Burns, describes best practice approaches for restoring Australian farm woodlands for birds, mammals and reptiles.
