In gardening, there’s also an assumption that things will vary from year to year. Too much sun or too little water and your plants could die or reward you with less than fruitful results. The current weather as well as the amount of attention, time, and money you invest in your garden could make a big difference in your output.
Agriculture in South Africa faces a variety of risks associated with climate change, such as:
-changes in rain patterns
-increased evaporation rates
-increased pests and diseases
-changes in diseases and pest distribution ranges
-spatial shift in optimum growing regions
To minimize these risks it is imperative that the agricultural sector adapts and mitigates its practices in response to climate change.
How does climate change affect South African farmers?
Climate change is predicted to reduce water availability and increase demand for irrigation. Water demand is expected to increase by between 20 and 50 percent over the 21st century. Rain-fed crops are likely to experience a decline in average annual yields. Reducing from 5% under present conditions to around 20% under high scenario conditions.
Changing temperature patterns
Demands of a growing population and increasing global consumption require more food from a limited land area in the next years.
How to manage the impact of climate change on agriculture
Both sides of the climate change equation need to be urgently and creatively managed. On the one hand, this involves an ongoing, concerted effort to reduce and where possible, eliminate destructive agricultural inputs to climate change. Measuring your greenhouse gas emissions and water consumption is essential for any farm to manage its carbon footprint or increase the efficiency of water use.

Recent scarcity of tomatoes due to climate change
Good-quality tomatoes have been tough to find in recent weeks, as heavy rains at the start of the year in the Limpopo valley wreaked havoc on harvests. Whether you are a home gardener or a commercial grower. Consumers will be feeling the pinch of high food prices even more than usual, as they will no longer have access to cheap tomatoes.
The drought has had a disastrous impact on the sector. Carrot production fell by almost 50% during January and February compared to the same period in 2016.
As climate change affects farming practices, farmers everywhere are now looking for opportunities to overcome the hardships brought forth by hot, humid weather. If you are a small-scale or large-scale farmer, there are things you can invest in to lessen the impact of climate change and remain competitive.
