Food security (FS) remains a pressing issue at the global scale. Current literature about FS points to a plethora of causes of food insecurity, among which climate change and the loss of biodiversity are critical to all facets of food security. Building on this notion, we advocate for a comprehensive understanding of drivers of food security, thus contributing by examining climate change and biodiversity as drivers of food security. The interest in this subject stems not only from the scientific community, but also from practitioners and policymakers. However, holistic encapsulation of the relevant literature addressing this subject is currently lacking. This review systematically analyses and categorises the drivers of FS induced by climate change and biodiversity. Following the Systematic Literature Review approach, 342 peer-reviewed studies were selected and synthesised. Our findings identified 11 categories of climate change drivers and 9 categories of biodiversity drivers of FS. These drivers were found

Global biodiversity loss, ecosystem collapse and national security: a national security assessment

This summer’s extreme weather and wars in Iran and Ukraine have made our need for food stockpiles more pressing than ever

Des milliers de personnes à travers quasiment tout le pays sont touchées par une infection liée à un parasite, dont une partie a été reliée à une salade vendue dans le célèbre fast-food Taco Bell. Les cas mortels restent rares, précisent les autorités américaines.

Farmers warn food shortages are just 10 days away – the signs suggest they’ve already arrived As farmers sound the alarm about a growing food crisis, experts say that Britain's food insecurity needs to be treated as a growing national security risk. As climate change and conflict affect fragile supply chains, the warnings are becoming impossible to ignore, writes disaster planner Lucy Easthope

Exclusive: Global investigation reveals 235 lawsuits have been brought against governments in five countries since 2010

Depuis environ deux mois, les Etats-Unis traversent l’épidémie de cyclosporose la plus grave de leur histoire. En effet, des milliers de cas d’infection intestinale parasitaire ont été recensés. Une enquête toujours en cours a déterminé la cause de la contamination : une simple laitue commercialisée dans une chaine de fast food.

Weather cycle threatens harvests worldwide, adding to inflation already fuelled by the Iran war

Members of parliament have demanded full publication of an explosive report by the UK’s spy leaders that found the collapse of ecosystems overseas would have catastrophic consequences for the UK’s national security, warning that the UK has “no future” if the findings are not urgently acted on.

The climate and nature crisis threatens all aspects of British life, from national security to the food supply. Despite the scale of the risks now facing the UK, there has been no comprehensive national emergency briefing delivered to the public by the Government.

Ce mardi, l’association Foodwatch dévoile que 80% des produits qu’elle a testés contiennent des pesticides interdits dans l'UE. Des épices Ducros aux thés Lipton, elle exige le rappel immédiat de ces aliments et une meilleure régulation.

L’association Foodwatch a mené une enquête sur 64 produits importés en France, en Allemagne, en Autriche et aux Pays-Bas. Sur 15 produits testés en France, 12 présentent des résidus de pesticides dont l’utilisation est interdite en Europe.

L’association de défense des consommateurs Foodwatch a appelé l’Union européenne à revoir son projet sur la sécurité alimentaire et les contrôles de pesticides, après avoir décelé des substances interdites dans des aliments importés de pays tiers, au-delà des limites tolérées.

Beneath the surface of the Pacific, a massive pool of heat is preparing to reshape global weather patterns. Time is running out to prepare for a climate shock of unprecedented scale. As 2026 unfolds, the Pacific Ocean is priming a catastrophic El Niño that threatens to cripple global food systems, trigger widespread economic instability, and shatter planetary temperature records.

Fytoplankton, de basis van zowat alle leven in de oceaan, bevat steeds minder eiwit en meer vetten en koolhydraten. Dat komt door de opwarming van het zeewater.

The world has become well versed in the importance of the strait of Hormuz to the world’s energy flows, but attention is increasingly turning to its vital role in another market – the fertiliser on which harvests depend. A third of the global trade in raw materials for fertiliser passes through the maritime choke point, which is also the route for 20% of shipments of natural gas, which is required to make it.

Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti

The fragility of the global food system fills me with dread – and the war with Iran has exposed just how close to collapse it is

Residents report terror of smoke-filled city, from potentially toxic rain, air and water to food scarcity and difficulty of escape

Three major Defence Agencies are quietly admitting what most still refuse to face: climate breakdown is coming for our food, and the cracks are already spreading. While the wealthy cling to logistics and illusion, the real defence strategy is soil and local growers who refuse to let their communities starve.

As climate and geopolitics shocks bite, countries are rebuilding food buffers. The UK clings to neoliberal ideas while households pay the price

Ecosystem destruction will increase food shortages, disorder and mass migration, with effects already being felt

From floods to droughts, erratic weather patterns are affecting food security, with crop yields projected to fall if changes are not made

UN GEO report says ending this harm key to global transformation required ‘before collapse becomes inevitable’

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petroleum-based waste and heavy metals have been discovered in pesticide and plasticizer formulations. These contaminations have now reached all forms of life. Widespread exposure to chemical mixtures promotes health and environmental risks. We discovered that pesticides have never undergone long-term testing on mammals in their full commercial formulations by regulatory authorities or the pesticide industry; instead, only their declared active ingredients have been assessed, contrary to environmental law recommendations. The ingredients of these formulations are not fully disclosed, yet the formulations are in general at least 1000 times more toxic at low environmentally relevant doses than the active ingredients alone u

“We’re losing 120 calories per person, per day, for every degree of global warming.” That stark data point from a 2025 Nature study signals more than a threat to food security, it points to a growing risk to global financial security. Food system instability exposes markets to cascading shocks: inflation, trade disruption, insurance losses and sovereign credit stress. Yet these risks remain largely unaccounted for in core financial systems.

Five of the seven breached planetary boundaries are linked to food systems. By transforming production and adopting a “planetary health diet,” we can halve food-related climate emissions and prevent millions of deaths, according to the 2025 EAT-Lancet Commission.

Purpose Animal emissions account for nearly 60% of total greenhouse gas emissions from the livestock sector. To estimate these emissions, the Food and Agriculture Organization of the United Nations (FAO) developed a dedicated module within the Global Livestock Environmental Assessment Model (GLEAM). Although previous studies have explored selected inputs for specific animals and emission types, a comprehensive analysis of all 92 inputs (parameters and emission factors) had not been conducted. This study aimed to identify the most influential inputs affecting ruminant emissions in GLEAM.

Exclusive: Increasingly extreme weather a threat to production and supply chains in Britain and elsewhere

2024 was the hottest year on record [1], with global temperatures exceeding 1.5 °C above preindustrial climate conditions for the first time and records broken across large parts of Earth’s surface. Among the widespread impacts of exceptional heat, rising food prices are beginning to play a prominent role in public perception, now the second most frequently cited impact of climate change experienced globally, following only extreme heat itself [2]. Recent econometric analysis confirms that abnormally high temperatures directly cause higher food prices, as impacts on agricultural production [3] translate into supply shortages and food price inflation [4, 5]. These analyses track changes in overall price aggregates which are typically slow-moving, but specific food goods can also experience much stronger short-term price spikes in response to extreme heat.

Slechts één land ter wereld produceert genoeg voedsel om zijn bevolking volledig te voeden volgens moderne voedingsrichtlijnen: het Zuid-Amerikaanse Guyana. Dat blijkt uit een grootschalige analyse van de productiecapaciteit van 186 landen, gepubliceerd in het toonaangevende tijdschrift Nature Food. De studie, geleid door onderzoekers van de Universiteit van Göttingen, toont aan dat de meeste landen ver achterblijven in het realiseren van een gezond voedingspatroon op basis van eigen productie.

Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.

A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

Antarctica's remote and mysterious current has a profound influence on the climate, food systems and Antarctic ecosystems. Can we stop it weakening by 2050?

Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

The world could fall short of food by 2050 due to falling crop yields, insufficient investment in agricultural research and trade shocks, according to Joe Biden’s special envoy for food security, Dr Cary Fowler. Fowler, who is also known as the “father” of the Svalbard Global Seed Vault, a global store of seeds for the most significant crops, said studies by agricultural economists showed the world needed to produce 50-60% more food by 2050 in order to feed its growing population. But crop yields rates were projected to decline by between 3-12% as a result of global heating.

Depleted soil leads to reduced yields, forcing farmers to rely on fertilizers that raise food production costs, consumer prices.

Microplastics and nanoplastics may be present in food, primarily from environmental contamination where foods are grown or raised.

L’association de défense des consommateurs a déposé ce mercredi 25 septembre deux nouvelles plaintes pour les traitements de purification illégaux auxquels les deux géants de l’eau en bouteille ont eu recours.
