TEXT A Reаd the fоllоwing previоusly reаd/seen cаse study and answer the questions that follow. My name is Themba, and I love being out on our farm with my dad. We grow and provide vegetables and herbs for Woolworths, and I'm proud of my dad because he is 'Farming for the Future.' That means we look at our whole farm as an ecosystem where we use the best practices of conventional and organic farming to grow good quality food in a responsible way. 'Farming for the Future' is part of the Woolworths Good Business Journey that helps farmers produce food in more sustainable ways. When you farm for the future, you start with healthy, balanced soil that supports plenty of micro-life and contains lots of good minerals that our crops need to grow well. We use lots of compost and worm droppings to build the fertility of our soils so that there is less need for artificial fertilisers. Everything is interconnected - because we have healthy soil and healthy plants, we have fewer problems with pests. Often, we can use clever, nature-friendly ways to control pests so that we use less pesticides. One of the great things about 'Farming for the Future' is that we save water. This is important, because water is a scarce (limited) resource in South Africa and agriculture uses up to 80% of the available fresh water. On some 'Farming for the Future' farms, water usage has been cut by 30% by using scientific methods to work out how much water the crops actually need, then watering using a drip irrigation system so that there's no water being wasted. We also manage our waste wat er properly to ensure that we don't pollute the river that runs through our farm. Because my dad has created a healthier, sustainable farm environment, we have lots of biodiversity on our farm. There are plenty of indigenous plants and trees so that lots of birds, mammals, insects, reptiles and frogs can live on our farm again. The best thing about my dad farming sustainably is that when I grow up and start farming too, there will still be healthy soil, enough clean water and lots of biodiversity for me, my children and my grandchildren.

What are the mechanisms in place that make this possible?
