Just under 40% of the entire terrestrial surface of our planet is used for agriculture, the vast majority of this for pasture. The land area which can be defined as wilderness – areas where humans have little influence – accounts for around 20% of the total land area and this extent is diminishing. These wilderness areas are, however, vital for the continued existence of wildlife plant species, and ecosystem services. As human populations grow and their lifestyle and consumption patterns become more resource demanding, the pressure on land use is increasing, and the multiple uses we have for land are often in competition with one another. Different cultures define ownership and rights to use land in contrasting ways, making land not only a precious resource but often a focus of contention too.
This report from the intergovernmental Organisation for Economic Co-operation and Development draws on the experiences of Brazil, France, Indonesia, Ireland, Mexico and New Zealand to examine how land use policy can be aligned with climate, biodiversity and food objectives.
This book explores the many factors influencing how land use decisions are made, including culture, values, ethics, trade, governance and pressure on farmland.
This report, commissioned by the UK countryside charity CPRE, assesses the current state of “county farms” - i.e. farms owned by local authorities, sometimes let out at below-market rates to assist new entrants to farming. It finds that the area of county farms has halved in the past 40 years as a result of being sold off.
This paper assesses the rate of soil erosion in different countries, aiming to separate the effect of varying landscapes from the effect of different national territories, e.g. through different agricultural policies or management patterns. As an example of a sharp discontinuity in soil erosion between neighbouring countries, visible on satellite images, the paper shows the difference between Haiti (with a high soil erosion rate) and the Dominican Republic (with greater forest cover and a lower soil erosion rate) - two countries that would have similar natural soil erosion rates in the absence of human activity.
This paper used satellites to observe the effect on yield of conservation tillage practices, such as reducing soil disturbance and leaving crop residues in the field, in the United States Corn Belt. The researchers found that long-term conservation tillage (i.e. from 2008 to 2017) was associated with a 3.3% increase in maize yields and a 0.74% yield increase for soybeans.
The UK’s Committee on Climate Change (CCC) has set out its policy recommendations on agriculture and land use, aiming to reduce the UK’s land-based emissions by 64% by 2050. The CCC estimates that its recommendations could produce £4 billion worth of benefits each year, including reduction of greenhouse gas emissions, recreational value of new woodland, better air quality and flood alleviation.
In the documentary Apocalypse Cow, environmentalist and writer George Monbiot argues that much of the current farming system (except for fruit and vegetable production) will be replaced by food from microbes, freeing up large areas of land for rewilding and carbon sequestration. He also calls for fruit and vegetable farming to be reformed, e.g. by using deep-rooted cover crops to build soil fertility.
This book explores how people can work with natural landscapes and harvest resources sustainably. Examples in the book include cocoa farming in Ghana, orchards in Kent, palm oil production in Borneo and monocrop cultivation in the UK.
This report from international consultancy SYSTEMIQ sets out how farmers in different regions across Europe can transition profitably to regenerative agricultural practices. It estimates that soil degradation currently costs the European Union €97 billion per year, mostly in damage to human health.
In this blog post, Samuel Smith of international sustainability non-profit Forum for the Future sets out research he intends to conduct on how regenerative agriculture is understood, the strategies that could be used to scale it up, and how the food system would be affected by widespread conversion to regenerative agriculture.
Some conservationists propose a “Half Earth” strategy, whereby half of the Earth’s land and half of its sea would be set aside for natural ecosystems. This paper assesses the number and geographical distribution of people who could be affected by the Half Earth conservation plan.
This paper modelled the food system changes in Europe that would allow enough afforestation, reforestation and avoided deforestation to meet European climate targets while also providing enough food. Most scenarios relied on significant yield improvements and reductions in meat consumption.
This review article finds that transforming the land sector (including agriculture, forestry, wetlands and bioenergy) could “feasibly and sustainably” contribute around one third of the emissions reductions needed to stay under 1.5°C of climate change.
This report from the Food and Land Use Coalition proposes ten critical transitions that could enable the food system to provide healthy diets for nine billion people by 2050 while also protecting the climate and biodiversity. The transitions are estimated to provide over 15 times more social benefit than their investment cost, which is likely to be less than 0.5% of global GDP.
This report from the US non-profit Croatan Institute quantifies the current US landscape of investments in regenerative agriculture, including in-depth analyses across asset classes (such as farmland and venture capital), and presents a series of recommendations for investors and stakeholders to build soil health and community wealth through regenerative agriculture.
In this report, Rosalind Sharpe of the Food Research Collaboration documents a series of interviews with farmers in the UK, showing whether and how human health factors into their work and decision making. The report was produced in collaboration with The RSA Food, Farming and Countryside Commission (read the Commission's report here).
The final report of the UK’s Food, Farming and Countryside Commission sets out 15 recommendations to policymakers, business and communities across the areas of healthy food, a ‘fourth agricultural revolution’ based on agroecological principles, and rural communities.
