           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.



               cross Africa, engineers and land
               managers are reimagining how
          Awe interact with the oldest human
           industry – and some of the most advanced
           tools available are now shaping how
           we care  for everything  from crops to
           community gardens.  The goal  is not only
           abundance, but resilience: to build systems
           that withstand uncertainty while keeping
           our green spaces thriving.

           The global smart agriculture industry is
           projected to be worth $22.5 billion by
           2025, with South Africa recording a 44%
           rise in AgriTech investment over the past
           five years. Behind these figures lies a shared   •   Controlled-environment farming: Hydro-  whether in a maize field or a golf course
