Average global yields of six staple crops could fall by more than 11% under a moderate warming scenario by the end of the century – even when accounting for how farmers could adapt to climate change, new research finds.
The study, published in Nature, examines changes in yields for cassava, maize, rice, sorghum, soya bean and wheat under two different warming scenarios.
But, unlike previous studies, it also factors in adaptive measures that farmers may employ to adjust to the changing climate.
It finds that implementing adaptation could reduce total yield losses by around 12% by the end of the century – although the world would still face “substantial losses”, it says.
The study also finds that the world’s “breadbaskets” – such as the US and Europe – will have less adaptive capacity than poorer regions, as their farming industries have been optimised for high yields, rather than resilience.
One researcher, who was not involved in the new study, tells Carbon Brief that these types of studies “are essential steps” towards better understanding adaptation in agriculture.
‘Partially protective’ adaptation
Globally, agriculture is projected to be one of the industries that is hit hardest by the impacts of climate change.
Along with rising average temperatures and changing rainfall patterns, increasingly frequent and severe weather extremes threaten planted crops.
However, large uncertainties remain around how farmers will adapt to future climate change.
Most previous research on the yield impacts of climate change either assumes that farmers will not adapt to the changes at all or that they can adapt infinitely, explains Dr Andrew Hultgren, an environmental economist at the University of Illinois Urbana-Champaign.
Hultgren, who led the new study, tells Carbon Brief:
“The question is: ‘What do real world farmers actually do?’ So that’s what we really set out to tackle…And what we find is that, essentially, neither of these extreme stories is really accurate. Farmers do adapt, but that adaptation is partially protective – not fully protective.”
The researchers model the impacts on crop yields under two emissions scenarios – moderate (RCP4.5) and very high (RCP8.5) – for two time periods – 2050 and 2098. They select six staple crops for their study: cassava, maize, rice, sorghum, soya bean and wheat.
For both emissions scenarios, the researchers apply projected future incomes consistent with SSP3 socioeconomic pathway. This portrays a “rocky road” of global development in the future due to rising geopolitical tensions driven by “regional rivalry”.
Under the moderate-emissions scenario, they find an overall decrease in staple crop yield of 8.3% in 2050 and 12.7% in 2098.
However, they find that these losses can be reduced somewhat by the introduction of adaptive measures, such as switching to different varieties of a crop or adjusting irrigation levels.
In order to account for adaptation, the researchers use data on crop yields from 12,658 sub-national regions to create a model that links changes in yields to exposure to extremely hot days.
This allows the researchers to project the impacts of adaptive measures without having to prescribe what, exactly, those measures would be, Hultgren says. Relatively lower losses on extreme heat days are “reflective of adaptation”, he adds.
In other words, if two regions with similar baseline climates and yields both experience a season of extreme heat, the one that has lower yield losses has more adaptations to climate change.
Factoring in adaptation and income growth, they find that the yield losses fall to 7.8% in 2050 and 11.2% in 2098 under moderate emissions. While these changes are relatively small, they are not insignificant, Hultgren argues:
“Twelve percent mitigation of losses is still a globally important amount of gains from adaptation.”
Dr Jyoti Singh, a climate-crop modeller at Columbia University’s Center for Climate Systems Research, tells Carbon Brief that the dataset assembled for the new study is its “most noteworthy strength”. Singh, who was not involved in the new work, adds that it “significantly contributes to empirical agricultural impact modelling”.
However, she says, there is a “big limitation” of the study in that empirical models are based only on past data – they cannot account for the full range of potential futures. Therefore, the results from the new study cannot be compared directly to results from models that more explicitly represent the processes that influence crop growth, she says.
Regional loss patterns
The losses are not equal across all six staples. The end-of-century losses range from just over 1% loss for rice yields to 22.4% loss for soya bean yields. This is because each of the crops has a different response to changes in temperature and rainfall.
The change in rice yield is particularly low, Hultgren explains, because the losses associated with overall warming are somewhat counterbalanced by yield increases due to rising nighttime temperatures.
In addition to the differences between crops, the researchers identify strong regional differences in the amount of future losses – as well as the extent to which adaptation will offset these losses.
In Africa, for example, the researchers project an overall yield decrease of 16% by 2098 with no adaptive measures in place. Adding in these adaptations reduces that yield loss to 11.6%. By contrast, adding adaptation to projections of staple yields in North America makes almost no change – reducing the losses from 21.0% to 20.8%.
The maps below show the percentage of yield losses for (clockwise from top-left) maize, soya bean, wheat, sorghum, cassava and rice in 2098 under a moderate-warming scenario that factors in adaptation.
The maps show that many of the staple crops studied suffer the most significant losses in current “breadbasket” regions of the world that produce much of the world’s calories, such as the US and Europe. In contrast, many lower-income, tropical regions see more modest losses. The authors write:
“Because such a large fraction of agricultural production is concentrated in these wealthy-but-low-adaption regions, they dominate projections of global calorie production, generating much of the global food security risk we document.”
However, Hultgren points out, subsistence farmers – particularly those who rely on cassava – will also be significantly impacted by climate change. The researchers identify the highest losses among the top two deciles of the global income distribution and the bottom decile.
This result was “surprising”, Hultgren says. Typically, he explains, research has shown that poorer areas are the hardest-hit by climate change.
He adds that the finding is reflective of the trade-off between average yields and adaptive measures. In high-producing regions, farmers have generally relied on planting the highest-yielding varieties, instead of crop varieties that might have lower average yields, but are more resilient to changes in climate.
Hultgren tells Carbon Brief:
“Adaptation is costly…That’s why losses in the breadbasket portion of the world are so large, because farmers have to essentially pay a high price. Either in terms of actual financial inputs or in terms of just average yield losses, they have to pay a high price in order to get the adaptation they need.”
‘Giving up breakfast’
By combining the projected yields for all six crops, the researchers also estimate the total impact of warming on global calories.
They find a “nearly linear” decrease in global calorific output of 554tn kilocalories per 1C of warming – equivalent to about 120 kcal per person per day per 1C. (The recommended daily intake is typically around 2,000kcal for women and 2,500kcal for men.)
Hultgren tells Carbon Brief:
“If you think about a 3C warmer future, that’s like a population that is giving up breakfast every day – that would be the level of the caloric output loss.”
That result “should raise questions” about global food security and international political stability, Hultgren says.
The study’s method of linking global calories to changes in temperature is one of the “key innovations” of the new study, Singh says. She adds that it “improve[s the] policy relevance” of the work.
Singh tells Carbon Brief:
“Real-world adaptation decisions, from changing crop types to investing in irrigation or adopting resilient varieties, vary significantly depending on policies and farmers’ knowledge, resource access and financial capacity.
“Studies like this one, even if not fully comprehensive, are essential steps toward understanding and incorporating adaptive capacity into yield projections, moving us closer to more realistic agricultural impact assessment efforts.”

DeBriefed 20 March 2026: Energy crisis deepens | Brazil’s new climate plan | New Zealand climate case
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Iran war fallout continues
WORK FROM HOME: The International Energy Agency has advised its member countries to take 10 steps in response to the ongoing energy crisis fuelled by the Iran war, including reducing highway speeds and encouraging people to work from home, said the Guardian. It came after retaliatory attacks between Israel and Iran continued to destroy energy infrastructure in the Middle East, causing energy prices to soar further, said Reuters.
SUPPLY DISRUPTED: The IEA also said it is prepared to make more of its member nations’ 1.4bn-barrel oil reserves available to help ease the impacts of what it called the “biggest supply disruption in the history of the oil market”, reported Bloomberg. The outlet noted that Asian countries have been hit hardest by the shortages, caused by a “near-halt” of shipping through the Strait of Hormuz.
EU SUMMIT: The energy crisis dominated talks at an EU leaders summit on Thursday, said Politico. Arriving at the summit, Spain’s prime minister Pedro Sánchez attacked other European leaders for using the energy crisis as an excuse to “gut climate policies”, according to the EU Observer. The Financial Times said that some European leaders have asked the European Commission to overhaul its flagship emissions trading system (ETS) by summer in response to the energy crisis.
COAL BOOST: In response to the conflict, utility companies in Asia are “boosting coal-fired power generation to cut costs and safeguard energy supply”, said Reuters. UN climate change executive secretary Simon Stiell told Reuters: “If there was ever a moment to accelerate that energy transition, breaking dependencies which have shackled economies, this is the time.”
Around the world
- WINDFARM WINDFALL: The Trump administration in the US is considering a nearly $1bn settlement with TotalEnergies to cancel the French energy company’s two planned windfarms off the US east coast and have it instead invest in fossil-gas infrastructure in Texas, according to documents seen by the New York Times.
- BUSINESS CLASH: Following “clashes” with the agribusiness sector, Brazil launched its new climate plan, which calls for a 49-58% reduction in greenhouse gas emissions from 2022 levels by 2025 and includes “specific guidelines for different sectors”, reported Folha de Sao Paolo.
- SALES SLUMP: Sales of liquified petroleum gas from India’s state-run oil companies have fallen by 17% this month due to cuts in deliveries to commercial and industrial consumers “amid the widespread logistical bottlenecks triggered by the Iran war”, said the Economic Times.
- CUBAN ENERGY CRISIS: The US imposed an “effective oil blockade” on Cuba, leaving the country facing its “worst energy crisis in decades”, reported the Washington Post. Meanwhile, Chinese exports of solar panels to the island have “skyrocketed” since 2023, it added.
- RECORD HIGHS: An “unprecedented” heatwave in the western and south-western US is “shattering dozens of temperature records” and could lead to drought in California in the coming months, reported the Los Angeles Times.
- VULNERABILITY CONCERNS: Landslides that killed more than 100 people in southern Ethiopia have “renewed concerns about Ethiopia’s vulnerability to climate-related disasters”, said the Addis Standard.

Captured
Carbon Brief this week published a significant update to its map of how climate change is affecting extreme weather events around the world. The map now includes 232 new extreme weather events from studies published in 2024 and 2025. Of these events, 196 were made more severe or more likely to occur by human-driven climate change, 12 were made less severe or less likely to occur and 10 had no discernible human influence. (The remaining 14 studies were inconclusive.)

New Zealand breaks new ground on climate litigation
This week, Carbon Brief speaks to experts about a first-of-its-kind climate lawsuit in New Zealand.
Earlier this week, representatives from two environmentally focused legal advocacy groups challenged the New Zealand government’s climate-action plan in court.
The plaintiffs argued that the measures laid out in the plan are insufficient to achieve the country’s legal obligation to hold global warming to 1.5C above pre-industrial temperatures.
The case could be “influential” in shaping lawsuits and rulings around the world, one legal expert not involved in the case told Carbon Brief.
Reductions vs removals
The new case contends that there are several issues regarding the New Zealand government’s response to climate change.
One of the key arguments the plaintiffs make is that New Zealand’s second emissions reduction plan, which covers the period from 2026-30, is overreliant on the use of tree-planting to achieve its targets.
When the plan was released in December 2024, it was “immediately clear that it was a pretty lacklustre plan”, Eliza Prestidge Oldfield, senior legal researcher at the Environmental Law Initiative, one of the groups behind the legal case, told Carbon Brief.
The plan called for large-scale planting of pine tree plantations, which are not native to New Zealand and have a high risk of burning. Because of this, there are concerns about how permanent any carbon removal provided by these plantations actually can be, experts told Carbon Brief.
Catherine Higham, senior policy fellow at the Grantham Research Institute on Climate Change and the Environment who was not involved in the case, said:
“The lawyers are arguing that there are real challenges with equating the emissions that you may be able to remove from the atmosphere through afforestation with actual emissions reductions, which are much more certain.”
‘Global dialogue’
While other climate lawsuits elsewhere in the world have also focused on the inadequacy of a government’s plan to meet its stated emissions-reduction targets, this is the first such case that addresses the role of removals head-on.
Lucy Maxwell, co-director of the Climate Litigation Network, told Carbon Brief that the lawsuit “builds on a decade of climate litigation” in national, regional and international courts.
Maxwell, who was not involved in the New Zealand case, added that there is a “real global dialogue” between, not just plaintiffs, but national courts as well. She said:
“[National courts] look to common issues that have been decided in other countries. They’re not binding on that court if it’s at the national level, but they are influential.”
Given that many other countries have legal frameworks requiring their governments to create plans outlining the pathway to their long-term climate targets, Prestidge Oldfield told Carbon Brief that other jurisdictions “should be interested in these questions around the level of certainty”.
Higham noted that, even if the case is successful, addressing the plan’s shortfalls will face its own set of challenges. She told Carbon Brief:
“A lot of these decisions are political and they can be politically contentious…Those [measures] have to be put into action through legislation and that is then subject to the usual political process. So that’s where the challenge comes in.”
While she could not speculate on the outcome of the case, Prestidge Oldfield said it was “very heartening” to see that both the judge and the opposing counsel “appreciated how much of a concern climate change is globally”.
She added:
“It’s not a given that the judge would even be interested in climate change.”

Around 300 scientists, civil servants, journalists and climate experts took part in the 11th annual Carbon Brief quiz on Wednesday 18 March 2026.
For the second time, this year’s quiz was hosted by Octopus Energy at its headquarters in central London.
In total, 39 teams participated – 25 teams in person and 14 teams joining via Zoom.
Competing teams reflected a wide range of climate change and energy professionals. The list included journalists, civil servants, climate campaigners, policy advisers, energy experts and scientists.
Organisations represented included: Council on Energy, Environment and Water (CEEW) in India; New Scientist; the Times; Business Green; the Bartlett School of Environment, Energy and Resources (BSEER), UCL; Verisk Maplecroft; BBC; World Weather Attribution; Grantham Institute at Imperial; DESNZ; WWF; European Climate Foundation (ECF); the ENDS Report; C40 Cities; Ricardo; Met Office; Meliore; E3G; Danish Meteorological Institute (DMI); Energy Transitions Commission; Carbon Tracker; Ember; Royal Meteorological Society; Civil Service Climate and Environment Network (CSCEN); Changing Markets Foundation; Cerulogy; Oxford Sustainable Law Programme; Université de Lausanne; University of Exeter; Centre for Environment and Sustainability, University of Surrey; UK Parliament; Skeptical Science; ECIU (Energy and Climate Intelligence Unit); Octopus Energy; DeSmog; Department for Transport and Royal School of Mines.
Teams were tested with five rounds of questions – general knowledge, policy, science and two picture rounds. (See the slideshow of the questions and answers below).
After two hours of playing, this year’s winners were announced.
Comprised of players from the Council on Energy, Environment and Water (CEEW) in India, last time’s second place team, “Emissions Impossible” won the coveted Carbon Brief trophy with a total score of 76 out of 100 available points.
In joint second place, with 59 points, were the “Potato-sized nodules”, a mixed team of journalists from New Scientist, the Times and Business Green.
Sharing second place, after leading at the half-way point, were “You cannot BSEERious” from the Bartlett School of Environment, Energy and Resources at UCL.
In fourth place, with 57 points, were “Risky Quizness”, from Verisk Maplecroft.
A certificate was awarded to the BBC for the best team name, as voted for by Carbon Brief staff: “High hopes [low confidence]”.
See the full leaderboard:
All the questions and answers from this year’s quiz can be found in this PDF document.
This year’s trickiest round was picture round two, which asked teams to match the quote to the author, with an average score of 5.9 out of 20 available points.
No team correctly guessed that “Chris Funk: Drought, Flood, Fire” was the source of the quote: “How greenhouse gases warm the atmosphere is pretty straightforward. It is really important that we understand this. But almost nobody does, because it is not something that we are taught in school.”
Science was the second hardest round, earning an average score of 6.1 points out of 20.
No team correctly guessed “religious leaders” as the least trustworthy source of climate information, according to a 2025 study using public polling from seven global south countries.
The highest-scoring round was general knowledge, with an average of 13.8 out of 20 questions answered correctly.
Carbon Brief would like to thank all the teams who took part and we look forward to hosting the quiz again in the spring of 2027.
If you would like to participate in next year’s quiz, please contact us in advance at quiz AT carbonbrief DOT org.

Just 1% of England’s land will be needed for renewables to help meet the UK’s climate goals by 2050, according to a first-of-its-kind framework.
There is enough land in England to meet climate and nature goals, while also producing more food and building new homes, according to the UK government’s new “land-use framework”.
Speaking at the framework’s launch on Wednesday, environment secretary Emma Reynolds said she hoped it would put an end to the idea that England faces “false choices” over “solar panels versus farmland”, or “growth versus environment”.
The policy was first planned by the Conservative government in 2022, but has been delayed many times.
It has been broadly welcomed by environmental groups, with Tony Juniper, the chair of Natural England, calling it a “vital step forward” towards “more joined-up approaches” to land use.
Below, Carbon Brief outlines the main points of the framework relating to climate change, nature restoration, food production, renewable energy and housing.
- What is the land-use framework?
- What does the plan say about how land in England should be used?
- What does the framework mean for different sectors?
What is the land-use framework?
The government’s land-use framework for England aims to set out a “coherent national vision” for using land.
The 56-page report is the first of its kind in England.
It focuses solely on England, but notes that the government will “work closely” with the devolved governments in Scotland, Wales and Northern Ireland to share best practice and “collaborate on cross-border issues”.
It is a “blueprint” to inform better decisions on optimising land use to produce food, host renewable energy, restore nature and build more homes, says environment secretary Emma Reynolds in the foreword of the framework.
The plan hopes to end the “fragmented approach” to tackling these issues, which has led to a “confused picture and missed opportunities for land to deliver multiple benefits”, Reynolds says in the foreword. She adds:
“We can plant trees to reduce flood risk to homes and farmland, locate energy infrastructure alongside nature-rich food production and ensure nature recovery is at the heart of resilient growth and development.”
The report says it will play a “critical role” in helping to deliver national and global commitments, such as carbon budgets and national biodiversity and climate plans.
The framework commits to creating a long-term assessment of climate change impacts on land use at 2C and 4C of global warming.
It also commits to setting up a “land-use unit” in the Department for Environment, Food & Rural Affairs to produce a map of “national spatial priorities” in England for, among other things, food production, nature and housing.
The government says it will update the framework every five years, outlining progress and next steps on implementation.
Currently, about 70% of land in the UK is used for agriculture – primarily livestock.
The chart below highlights how land is currently allocated in the UK (left) and how much overseas land is used to produce food for the UK (right).
The government’s land-use framework for England has been long-awaited and much-delayed.
The recommendation for the report first came in the 2021 National Food Strategy, an independent report led by businessman Henry Dimbleby.
It recommended creating a rural land-use framework to give “detailed assessments” of the best ways to use land in England.
The former Conservative government committed to produce such a report in a June 2022 food strategy.
This strategy said that a land-use framework for England would be released in 2023 “to ensure we meet our net-zero and biodiversity targets”, among other aims.
The publication was, however, delayed many times.
The Labour government launched a consultation on the framework in January 2025 and the final report was eventually released on 18 March 2026.
The framework is a “long-awaited opportunity for real change”, says Roger Mortlock, chief executive of the environmental charity Campaign to Protect Rural England (CPRE), in a statement.
Mortlock welcomes its “ambition”, but says that the way in which land tradeoffs are considered locally and nationally “will be key to its success”.
A report released by CPRE earlier this week, however, said that the framework is “unlikely to be the silver bullet many are hoping for”.
What does the plan say about how land in England should be used?
The framework uses high-resolution modelling – what it calls the “most sophisticated analysis” of its kind – to examine how England can use land to meet climate, nature, food and housing needs.
One key finding is that England has enough land to meet all of its objectives, if land is used efficiently.
This means that England has “enough land to deliver our objectives for nature restoration and development without reducing domestic food production or compromising on these objectives”, according to the framework.
It adds that efficient land use means “playing to the strengths” of England’s varied landscape. This involves, for example, prioritising the restoration of peatlands in north-west England and temperate rainforests in the south-west.
The chart below shows the percentage of land in England currently used for different purposes, as well as how this distribution will need to change by 2030 and 2050, if the UK is to meet its goals, according to the framework.
According to the framework, just 1% of England’s land will need to be taken up by renewables, such as solar and onshore wind, by 2050.
However, the framework does note that there is “inherent uncertainty” in projecting energy use by 2050 and says that the amount of land required for renewables may be nearer to “more than 2%”, depending on how quickly solar and wind is deployed in the future.
A further 6% of England’s land should be used for achieving climate and nature goals, according to the framework.
(A Defra official tells Carbon Brief that the framework’s projections for renewable energy and tree-planting were not as ambitious as those in the Climate Change Committee’s central pathway to net-zero, but are in line with the government’s carbon budget delivery plan for 2035.)
Speaking at the launch of the framework, environment secretary Emma Reynolds said that the framework shows that there are no “false choices” between “solar panels versus farmland” or “growth versus environment”, adding:
“The problem has never been scarcity of land. It has been a shortage of clarity.”
What does the framework mean for different sectors?
The framework sets out a “vision” for land use in several areas, such as housing, energy, food and nature by 2030 and 2050.
It also details what the government is currently doing to achieve these aims and makes pledges for more action down the line.
Below, Carbon Brief has detailed the key points around renewable energy, tree-planting and nature restoration, food production and housing.
Renewable energy
The report notes that the need to produce extra electricity to meet growing demand from, among other things, electric vehicles, heat pumps and data centres is “changing the way land is used across England”.
The UK plans to produce at least 95% of electricity from low-carbon sources, such as wind, solar and nuclear, by 2030.
Despite this, the report says that solar and wind will continue to make up a “small proportion of land use”. It says that, by 2030, much of this land will be “managed sustainably” for dual purposes, such as placing solar panels on the same land as growing crops.
Currently, around 21,000 hectares of land in the UK is covered by solar panels – which, as Carbon Brief has previously noted, is much less than the land used for golf courses.
By 2035, an additional 129,000 hectares of land is estimated to be used for solar and wind energy in England, with some of this land also used to produce food at the same time.
If achieved, this will account for 1% of land in England and 2% of the UK’s agricultural area.
This estimate is based on the assumption that all extra solar will be installed on the ground, which the report says is a “highly conservative and unlikely scenario” given that many panels are anticipated to be placed on rooftops.
This makes the 2035 figure an “upper-bound” estimate, says the report.
By 2050, around 155,000 hectares – roughly equal to the size of Greater London – will be used for renewables, the report estimates, adding that this is based on trends from historical data and not future scenarios.
The report adds that it is possible that more land than this will be needed to meet energy goals past 2035, however, citing the “inherent uncertainty” in figuring out what the mix of electricity sources will look like by 2050.
By 2030, coordinated planning of electricity networks will encourage rural investment, “such as through new data centres”, the report claims.
By 2050, the report says that better land-use planning will lead to a “fairer and more efficient distribution of solar and wind infrastructure across England”.
There will also be better electricity connections to renewables, much of which will be delivered alongside “productive agriculture”, such as by installing solar panels above crops – known as agrivoltaic farming.
The report says that any land-use change decisions should be made based on a number of factors, drawing from “local knowledge, values, data and priorities”.
It notes that development of wind and solar infrastructure in rural areas should give local communities the “opportunity to benefit from local clean energy”.
Tree-planting and nature restoration
According to the framework, 6% of England’s land will need to be used for achieving climate and nature goals by 2050.
This kind of land use includes restoring England’s carbon-dense peatlands, planting new woodlands and restoring heathland habitats.
As part of the analysis, the framework takes a detailed look at what parts of England would be best suited for nature restoration. It says:
“Habitat creation and restoration should be directed to the places where it can have the greatest ecological impact, help to reconnect fragmented landscapes, support priority species and deliver the greatest contribution to nature recovery.”
The chart below, taken from the framework, shows where in England has the greatest potential for nature restoration in dark green.
The analysis finds that north-west England has high potential for nature restoration, largely because it is home to the vast majority of the country’s carbon-rich, but degraded, peatlands.
Other areas identified include the south-west, which could be suitable for “grassland restoration and broadleaf woodland creation” and the south-east, where new grasslands could be planted, according to the framework.
The framework adds that the UK government remains committed to protecting 30% of land for nature by 2030, an international goal set under the Kunming-Montreal Global Biodiversity Framework.
However, it notes that, at present, just 7% of England’s land is protected for nature – with just four years to go until the deadline.
Speaking at the launch of the framework, nature minister Mary Creagh acknowledged that meeting the target remains a large challenge.
She added that her department was currently on a “data sprint” to try to account for all kinds of land that may not currently be classified as being protected for nature, despite serving this purpose.
Food production
The new framework extensively discusses how to balance food production with other uses for land, such as producing renewable energy and building homes.
The government says it is generally not suggesting land-use change on the country’s “best agricultural land”.
The framework focuses instead on using farmland to fulfil dual purposes, “rather than taking land out of production entirely”.
The goals outlined in the framework include increasing domestic food production in England, which the report says is “feasible according to our projections”.
Currently, the UK produces around 60% of its own food, importing the rest from abroad.
By 2030, the “vision” outlined in the framework says that farmers and other land managers will have better long-term clarity and more information on improved ways to use their land.
By 2050, meanwhile, farmlands will be managed to prioritise “sustainable food production and environmental benefits”, it says.
At this stage, the framework estimates that 480,000 hectares of farmland could be used primarily for food production, while also bringing environmental and climate benefits such as planting trees or restoring grassland habitats.
Agricultural land will be used to balance food production and other outcomes. A footnote in the report says that this will broadly lead to a “mosaic of different landscapes” – semi-natural land, low-intensity farmland and higher-intensity farmland.
It also says that, by 2050, farmland will be more resilient to climate change impacts through actions such as planting trees for flood and drought resilience.
All projected scenarios in the analysis behind the framework focus on producing food “more sustainably from less land”, the report notes.
The agricultural land-use change recommendations in the framework differ across the country. If focusing on improvements to water quality and biodiversity, for example, it recommends looking at areas with intensive agricultural production in the east of England.
This is due to these areas using high quantities of fertilisers, which can wash off fields and run into rivers and other waterways. This lowers water quality and harms plants and animals.
The government commits to developing sectoral growth plans, starting with horticulture and poultry, to provide a framework to boost production and “maintain food security”.
The government also promises to support making “under-used land” available for communities to grow food and recover nature, “where appropriate”. This refers to inactive land that is not suitable for other developments.
The report is a “step in the right direction”, says Tom Bradshaw, president of the National Farmers’ Union. He adds that it is “positive” to have “explicit recognition” of using land for multiple purposes and a government commitment to maintain food production.
Bradshaw notes that “challenges remain about delivering against the ambitious objectives as the first 2030 milestone approaches”.
Housing
Reynolds says that this framework can help to “speed up house-building and infrastructure delivery”.
The report says that, by 2030, improved planning will enable areas to facilitate housing and development “whilst protecting and enhancing the environment”.
It adds that, where appropriate, developments will be higher-density to “make the best use of land within our towns and cities”.
By 2030, biodiversity net gain – a planning requirement to improve habitats while building developments – and nature-based solutions will also be used to ensure development “leaves the natural environment in a measurably better state than it was in beforehand”, the report says.
It adds that timber production will be expanded to provide “low-carbon building materials”.
By 2050, meanwhile, the framework says planners will be able to more easily assess how suitable areas are for development “using a streamlined digital planning service and decision support tools”.
These tools – built on a range of data sources – are intended to reduce the number of homes built in areas at risk of flooding, the report says.
One in four homes in England are projected to be at risk of flooding by 2050, under a high-emissions scenario, the report outlines.
The report notes that the government is proposing a “default yes” to some planning applications for developments near well-connected transport stations.
High-demand areas “need to be powered locally and sustainably”, it notes, and using technologies such as rooftop solar to “make use of existing built land for electricity generation” can reduce land pressures elsewhere.
