Feeding Tomorrow - Food Security in a Changing Climate

Food lies at the centre of the climate conversation in a way that energy and construction do not.

Everyone eats. The consequences of a failing food system are not abstract - they show up in prices, availability and the kind of social instability that tends to move fast when it starts. And yet food and agriculture receive less sustained board-level attention than almost any other area of climate exposure, despite being one of the most directly and immediately affected.

This is the fourth blog in my series on climate and the sectors I work across. It is also, in some ways, the most personal. I work with Take Root Bio — a business in controlled environment agriculture — as an adviser and NED. The work they are doing is a direct response to the pressures this blog describes. I have seen at close quarters what serious innovation in food production looks like, and equally, how hard it is to scale.

What Is Already Happening

Extreme weather in 2025 caused $50 billion in agricultural losses globally. Some farmers are reporting yield drops of up to 40% for staple crops including wheat, rice and maize. River systems that have long served as supply routes for food distribution - the Mississippi, the Rhine - are becoming unreliable due to drought and flooding. Growing seasons are shortening in some regions and becoming dangerously unpredictable in others.

The result is a food system under sustained pressure. Not crisis in every market, but consistent volatility in prices, yields and availability that is working its way through supply chains and onto the shelves and menus that consumers interact with every day.

For businesses operating in food and agriculture - growers, processors, retailers, hospitality groups = this is not a future risk. It is a present one.

The Innovations Worth Watching

Vertical farming and controlled environment agriculture have moved from novelty to serious commercial consideration. Urban vertical farms using hydroponics, aeroponics and full-spectrum LED lighting can produce food year-round using up to 90% less water than conventional agriculture and with no pesticides. The challenge has been profitability and energy cost. The businesses solving those problems - by integrating renewable energy, waste-heat recovery and AI-managed growing systems - are the ones to watch.

Regenerative agriculture is gaining ground at the other end of the scale. Practices such as cover cropping, no-till farming and rotational grazing rebuild soil carbon and water retention over time, turning farmland from a source of emissions into something closer to a carbon sink. This is not cutting-edge technology. It is a return to farming methods that work with natural systems rather than against them, supported by better data and more sophisticated measurement.

Real-time data tools - satellite imaging, IoT soil sensors, predictive analytics - are giving producers earlier warning of crop stress and more time to adapt. Alternative proteins, including lab-grown meat, insect-based protein and plant-based foods, are reducing dependence on livestock systems that account for nearly half of agricultural methane emissions.

The technology exists. The question, as in construction and energy, is the pace at which it is being adopted,and what determines that pace.

The Organisational and Governance Challenge

In my experience, the businesses in this sector that are adapting most effectively are not necessarily the largest or the best resourced. They are the ones where leadership has taken a clear-eyed view of their exposure, made deliberate decisions about where to invest ahead of regulatory and market pressure, and built governance structures that support long-term thinking alongside short-term delivery.

For a board operating in food and agriculture, the relevant questions are practical ones. What does our supply chain look like if the weather patterns of the last three years become the norm rather than the exception? How are our growing or sourcing regions expected to change over the next decade? What assumptions are built into our cost model about water availability, input prices and logistics reliability?

These are not specialist questions. They are the kind of strategic risk questions any experienced NED should be raising. The fact that they are not being raised consistently in many boardrooms in this sector is, to my mind, one of the more significant governance gaps in UK business right now.

What This Requires from Leaders

Food security in a changing climate will not be solved by technology alone. It will be shaped by the decisions made in boardrooms, by investors allocating capital, and by policymakers willing to support the transition from industrial monoculture to more resilient, diverse food systems.

For the leaders and boards operating in this space, the ask is not to solve the whole problem. It is to understand your piece of it clearly, to ask the questions your organisation may be avoiding, and to build the kind of governance that supports honest assessment of risk and genuine commitment to change.

That is where I think the work matters most. And it is where I am glad to be involved.
