Showing results for: Land use and land use change
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.
Climate mitigation policies rarely account for the time lags associated with land-based greenhouse gas mitigation policies such as reforestation, bioenergy with carbon capture and storage (BECCS) or reduction of agricultural emissions, argues this paper, making it unlikely that commitments under the Paris Agreement will be met.
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 paper presents a ‘carbon benefits index’ to measure how land use change contributes to global carbon storage and reduction in greenhouse gas emissions. The index accounts for both the carbon that could be stored if the land were reforested, and the carbon emissions of producing the same food elsewhere.
The latest issue of The Land magazine, of which FCRN member Simon Fairlie is an editor, has a 40-page section on meat-eating and veganism, with about 20 articles and short features representing a variety of viewpoints.
So-called natural climate solutions in the United States (such as changing management of forests, grassland and agricultural land) could create annual emissions savings equivalent up to 21% of current US emissions according to this paper.
In this report, the InterAcademy Partnership expresses concern over the current state of global food systems and nutrition, and also identifies science-based initiatives that could contribute to solutions.
This paper presents maps of global land use change from 1992 to 2015, showing net increases in the area of agriculture, grassland and settlement, and net losses in the area of forest, wetland, shrubland, sparse land, bare land and water.
Current land use patterns in the UK are not sustainable, according to this report from the UK’s Committee on Climate Change. The report claims that, if current farming trends continue, there will not be enough land in the UK to both meet future settlement needs and maintain current levels of per capita food production. The report also predicts significant negative effects of climate change on soils, water, vegetation and wildlife.
6.5–15.4 million hectares of private land in Brazil could become legally available for deforestation, because expansion in the land area designated as conservation units or indigenous reserves could trigger a legal mechanism whereby the area of legal reserves for native vegetation may be decreased.
This interim report from the UK’s Food, Farming and Countryside Commission inquiry into the challenges that the food industry, farmers, and the countryside face sets out the progress that the inquiry has made so far.
In this piece for The Conversation, researcher Elise Wach discusses the consolidation of farmland in the UK and rising farmland prices. According to Wach, there were nine times more small farms in England 15 years ago than there are today, and the number of high-intensity large farms is rising swiftly.
WWF’s 2018 Living Planet Report finds that population sizes of thousands of vertebrate species have declined by 60%, on average, between 1970 and 2014, land degradation seriously impacts 75% of terrestrial ecosystems, and current species extinction rates are 100 to 1000 times higher than the background rate. The report attributes these impacts to rising demand for land, water and energy, and explores the impacts of agriculture, fisheries and deforestation.
This paper searched for areas of land in Africa where palm oil could be cultivated productively with minimal impact on primate populations. The results showed that such areas are rare: the areas that are suitable for growing palm oil also tend to be areas where primates are highly vulnerable.
A feature in the New Food Economy explores how the difficulty of finding farmland at an affordable price presents a barrier to new farmers in the United States. Two online tools have been developed to help farmers find land: Farm to Farmer, which matches farm owners to land seekers, and the Finding Farmland Calculator, which aims to demystify the costs of owning farmland.
27% of global deforestation since 2001 has been caused by permanent land use change for producing commodities (such as beef, soy and palm oil), according to a recent paper. The researchers used satellite imagery to assess 10 km by 10 km grid cells across the globe and categorised each cell by likely forest disturbance type: commodity production, shifting agriculture, managed forestry, wildfire, or urbanisation.
If the US were to shift to entirely grass-finished beef (vs. grain-finished), then the US cattle population would have to increase by 30% relative to today, because grass-fed cattle gain weight more slowly than those fattened in feedlots. Furthermore, existing pastures would have to become 40%-370% more productive to avoid converting more natural habitat to farmland or competition with human food supply. Methane emissions from the cattle’s digestive systems might increase by 43%, again because of slower growth rates.
