SMART LANDSCAPES: FARMING AND
THE FUTURE OF GREEN SPACES
The technologies transforming African agriculture are not confined to distant fields
and vast farmlands. They are equally relevant to the places many of us call home:
landscaped estates, golf courses and urban green belts where water, soil, and plant
health demand constant care. In an era of climate volatility and rising resource
pressure, the same systems that help farmers secure resilient harvests can help our
estates maintain vibrant, sustainable landscapes.
