MAINSTREAMING CLIMATE CHANGE ADAPTATION IN AGRICULTURAL EXTENSION
This has been done for us using the same historical data from the met stations
that was put in the graphs for events – see the following slides
SLIDE 21 - EL NINO, ORDINARY AND LA NINA YEARS AT MAKOHOLI
(FROM IRI)
SLIDE 22 - MEAN NUMBER OF RAIN DAYS (MAKOHOLI)
Go through the figures in the table on the slide
These show us that for Makoholi:
In El Nino years there were less days with rain in every month (than in normal or
La Nina years)
This difference is greater in the first 3 months of the season than the second
In La Nina years there are more days with rain in some of the months than in
normal years. Also there are more days with rain in all months than in La Nina
years
SLIDES 23 – 25 GRAPHS COMPARING EL NINO, LA NINA AND NORMAL
YEARS
These slides support what has been said above.
SLIDE 26 – LOOKING AT EL NINO AND LA NINA YEARS
- These can be forecast before the season
- El Nino ..... Does it mean lower rainfall at our site(s)? YES for Makoholi
(We need to do the same analysis for other sites)
- La Nina .... Does it mean more rainfall at our site(s)? NOT SO CLEAR,
BUT THEY ARE NOT LIKELY TO HAVE LOW RAINFALL for Makoholi
(We need to do the same analysis for other sites)
- This means that (for Makoholi at least) telling farmers whether it is going
to be El Nino, La Nina or neither could be very useful
