Showing results for: Land use and land use change

This report details the methodology used to create a new online tool which can help companies set science-based emission targets and incorporate land-use change into their mitigation strategies. It is part of the Science Based Targets initiative run by the Carbon Disclosure Project (CDP) CDP, UN Global Compact, the World Resources Institute (WRI) and World Wildlife Fund (WWF).

With global trade, UK consumption patterns are displacing cropland use to other countries. This paper by FCRN members Henri de Ruiter, Jennie Macdiarmid and Pete Smith looks at the environmental consequences of competition for global agricultural land and specifically at the total land footprint associated with the total livestock product supply in the UK.

This article by agricultural researchers in Spain reviews the historical changes in land use and soil management practices, and examines how these changes have contributed to soil erosion in the past, before presenting modelling data to show how soil erosion may impact on agricultural yields in the future.

This paper in Nature addresses the question of whether a warming planet leads to increased CO2 emissions through heightened activity by soil microbes. It finds that this positive feedback mechanism exists and is likely to be of great importance in the future global carbon budget.

One of the greatest challenges of this century is figuring out how to feed more people, while significantly reducing greenhouse gas emissions from agriculture, just as other demands on land - for example, for sequestration and bioenergy production - are increasing.

This blog on the World Resources Institute’s (WRI) website discusses their collaboration with food multinational Mars in developing science-based sustainability targets for climate, land use, and water.

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.

A key ingredient in junk food is vegetable oil. 60% of this oil is from oil palm and soybean, production of which has been expanding in Southeast Asia and South America, resulting in widespread deforestation and biodiversity loss. In this article, the authors calculate the amount of current deforestation due to vegetable oil consumption (through junk food) and extrapolate vegetable oil demand to predict the deforestation future consumption patterns would cause by 2050.

This report by Zero Carbon Australia, outlines how research on greenhouse gas emissions from land use (agriculture and forestry) can be reduced to zero net emissions, coupled with economic opportunities and increased resilience in the face of climate change. The land use sector is the second largest source of emissions in Australia and is highly exposed to the impacts of climate change. 15% of total emissions in Australia are from the agriculture and forestry sectors, the largest component of which is land clearing for grazing.

In this letter, over 100 researchers and practitioners argue that media coverage of the 2016 International Peat Congress (the first to be held in the tropics) was dangerously misleading in its assertions that peatland management under palm oil plantations was sustainable (see for example this news article by BorneoPost). They argue that such articles, by downplaying the issues imposed on peatland ecosystems by agriculture, undermine recent real and promising advances in tropical peatland management.

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.

Initiated in 1999, the Grain-for-Green Program was set up primarily to reduce soil erosion and uses cash payments to incentivise people to replant trees on sloped crop and scrubland. This study examines the effects on bird and bee species in the scheme across the country. It finds that the program has not greatly benefited birds and bees due to the common practice of monoculture tree planting.

The EU uses more than its fair share of global land; in 2010 the amount of land needed to satisfy our consumption of agricultural goods and services was 43% greater than the land available within its boundaries. This report stresses the responsibility that the EU has to measure, monitor and reduce its global land footprint.

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 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.
