Increase: Having to cut the grass more often & a weed population
explosion! Generally the bush is getting denser. Mopane trees, in scrub
form, are slowly taking over grasslands in Kruger - good for the prey,
difficult for the predators & game-viewers. Occasional wildfires are a
natural form of control. Statistics indicate that malaria may be on the
march again - the vaccine has arrived just in time! Essentially, South
Africa is a water deficient country so from a human perspective with an
increasing population it should be beneficial in the long term.
Decrease: great hardship all round.

What are the long term implications of an increase/decrease in the average?
You are in savannah country, I think?

The 65 year average seasonal rainfall for Phalaborwa is 540mm. Higher
global temperatures allows the air to hold more water vapour and
therefore the rainfall would be expected to increase. We had 730mm in
2019/20 & 947mm in 2020/21. This season seemed to be following the same
trend with 627mm already recorded by the end of Jan. Now, Feb. is
usually our wettest month & March quite wet too so it looked like we
were heading for over 800mm again. Mother Nature obviously had other
ideas. Only 14mm in Feb. & 2mm in March so far. Unseasonably hot &
unpleasant too - mid 30's (C) virtually every day. The rainfall in the
latter part of the season mostly emanates from cyclonic activity in the
Mozambique channel between Madagascar & the continent. The people of
Madagascar have already been battered by several but only only one had
made landfall in Africa & then in the north of Mozambique & Mrralawi. This
year all the others peeled of and went back into the Atlantic - what a
waste - the ocean is full enough already! Perhaps we will still make 700mm?
