The Global Challenge

More people.
Less water.
A system under pressure.

The world's agricultural systems are facing a convergence of crises — population growth, water scarcity, climate disruption, and decades of soil degradation. These are not future risks. They are today's reality.

Four Interconnected Challenges

These are not separate problems.
They are one system failing.

Water scarcity, soil degradation, fertiliser inefficiency, and climate unpredictability are all connected through the soil. Address the soil — physically, not chemically — and the entire system begins to stabilise.

01

Growing populations. Shrinking capacity.

The world's population is on course to reach 9 billion by 2050 — an increase of roughly 25% from today. Feeding this population will require agricultural output to rise by at least 50%, while the natural resources available to achieve this are under increasing strain.

Today, an estimated 673 million people experience hunger. The majority are in Sub-Saharan Africa and South Asia — precisely the regions where agricultural systems face the greatest pressure.

02

Agriculture uses most of the world's fresh water — and wastes much of it.

Agriculture accounts for approximately two-thirds of all global fresh water withdrawals. Yet much of this water is never effectively used by crops — lost through uncontrolled evaporation, surface runoff, and deep percolation past the root zone, taking dissolved nutrients with it.

2.4 billion people currently live in countries experiencing water stress. Almost 40% of the world's cropland already operates under conditions of water scarcity — and the figure is rising.

03

The seasons farmers relied on no longer behave as expected.

For generations, farmers in Africa, Latin America, and Asia planned their planting cycles around predictable wet and dry seasons. Climate change has dismantled this predictability. Today, droughts occur within what should be wet seasons. Floods strike in dry months.

Africa is warming at up to 1.5 times the global average. The gap between a good harvest and a failed one is narrowing to a few weeks of erratic rainfall.

04

Decades of mismanaged inputs have left the soil depleted.

Healthy soil is not simply a growing medium — it is a living system. When this system is degraded, no amount of irrigation or fertilisation can compensate. Across Sub-Saharan Africa and other key agricultural regions, decades of intensive mono-cropping and excessive chemical input use have progressively destroyed this living infrastructure.

Degraded soil responds poorly to fertiliser. Low yields drive more application. More application drives further degradation. Without an intervention that addresses the soil's physical structure, this cycle continues.

Climate Events — Africa

Predictability has ended.

East Africa

Five consecutive failed rainy seasons

From 2020 to early 2023, East Africa experienced five consecutive failed rainy seasons — the worst drought in 40 years. Harvest failures, livestock losses, and water scarcity left 4.35 million people requiring humanitarian aid.

Southern Africa

Worst drought in a century

The 2023–2025 regional drought was classified as the most severe in over 100 years. Six countries declared national drought disasters. Cereal yields fell 16% below five-year averages.

Nigeria & West Africa

Flooding followed by drought

In 2024, flooding displaced over 4 million people across West Africa. In the same period, other parts of the region suffered crop failure from drought — both extremes happening within the same growing season.

Africa-Wide

13 million people affected in 2025

The WMO's 2025 State of Climate in Africa report documented over 13 million people affected by climate-related shocks in a single year, with flooding accounting for more than half of all recorded climate hazards.

The Soil Problem

A self-reinforcing cycle
of degradation.

Fertiliser is frequently applied in the wrong quantity, at the wrong time, or to soils that are not yet capable of responding to it. Much of it is washed away before the plant can absorb it — accelerating soil acidification without improving yields.

Blanket fertiliser recommendations

Generic dosage guidelines ignore the enormous variability in soil composition, moisture levels, and crop types — resulting in systematic over- or under-application.

Fertiliser lost to rainfall and runoff

In rainfed agricultural systems, a large share of applied fertiliser is washed out of the root zone before it can be absorbed — wasting resources and polluting waterways.

Chemical inputs destroying soil biology

Excessive use of synthetic pesticides and herbicides eliminates the microorganisms that keep soil alive, productive, and resistant to erosion.

A self-reinforcing cycle

Degraded soil responds poorly to fertiliser. Low yields drive more application. More application drives further degradation. Without physical intervention, this cycle continues.

These are not separate problems.

Address the soil — physically, not chemically — and the entire system begins to stabilise. That is the principle behind HYDRONICA®.
