Benefits of biotechnology to small scale farmers: Case Study Makhatini MR THEMBITSHE JOSEPH BUTHELEZI (T J) UBONGWA CAPE TOWN BIOTECHNOLOGY INFORMATION DAY 14 TH AUGUST 2002

WHAT IS UBONGWA? o Ubongwa is an umbrella association of 50 smallholder farmer associations in KwaZulu-Natal. o I am the chairman of Ubongwa.

GENETICALLY MODIFIED COTTON IN SOUTH AFRICA (GM) oInsect resistant cotton (Bt-cotton) first grown in Makhathini 1996 / 97. o My farm was one of the first four farms to try GM cotton in 1996 / 97. o I planted 2ha with GM cotton and 2ha with conventional cotton in 1999 / 2000. o Other farmers from different associations came to see my GM cotton.

Bt-cotton vs. non Bt-cotton (both planted at the same time) Bt-cotton Small compact plant Many mature bolls ready for harvest -3 sprays for non bollworm pests Non Bt-cotton Large plant, excessive vegetative growth Difficult to spray Few bolls to harvest 10 sprays for all insect pests

SMALLHOLDER ADOPTION OF Bt COTTON IN THE MAKHATINI Statistics - 1999/00 to 2000/01 Growth in no. of Bt-cotton users: 57% Bt-cotton: 52%non Bt cotton: 48%

IMPLICATIONS FOR SMALLHOLDER GROWERS NEGATIVES Affordability Technology fee pests Emergence of other pests which were previously controlled by bollworm sprays Jassids, green stinkbug These are easily controlled with 1-2 sprays Are not as damaging as bollworms NEGATIVES Affordability Technology fee pests Emergence of other pests which were previously controlled by bollworm sprays Jassids, green stinkbug These are easily controlled with 1-2 sprays Are not as damaging as bollworms

IMPLICATIONS FOR SMALLHOLDER GROWERS POSITIVES Savings Time (free up time to do other household tasks) Water (water provision for spraying difficult) Costs of pesticides Labour (20 km to spray 1 ha with knapsack) Transport (to buy pesticides)POSITIVES Savings Time (free up time to do other household tasks) Water (water provision for spraying difficult) Costs of pesticides Labour (20 km to spray 1 ha with knapsack) Transport (to buy pesticides)

IMPLICATIONS FOR SMALLHOLDER GROWERS CONT. POSITIVES Safety Reduced handling of hazardous chemicals Improved bollworm control efficiency Weather no longer plays a role in spray efficiency Technology provides superior bollworm control Improved ecologyPOSITIVES Safety Reduced handling of hazardous chemicals Improved bollworm control efficiency Weather no longer plays a role in spray efficiency Technology provides superior bollworm control Improved ecology

OVERALL IMPACT OF Bt COTTON IN SOUTH AFRICA FOR SMALLHOLDER FARMERS Impacting more on smallholder farmers than commercial ~ 85% of smallholder area is Bt cotton Increased yield and profit for both commercial & smallholder farmers. We used to get 6 tons/ha of cotton, now we get 9.8 tons/ha using Bt cotton.

THE DIFFERENCE GM COTTON HAS MADE TO ME Less labour and time needed to grow cotton so I can grow more. I used to grow 4ha, now I can grow 12ha of cotton and I plan to grow 25 ha next year. Now I have enough money to build a house.
