Malawi has recently experienced an increased incidence of climate change-related hazards.
More droughts and floods have occurred in the last decade (2000 - 2010) than in the past
three decades before (1970 - 2000). Agriculture is one of the most vulnerable sectors and
consequently has suffered from the negative impacts of climate change. As a result,
communities, NGOs and the government of Malawi are adapting (adjusting to continue
deriving benefits) to the changing conditions in order for Malawian farmers and their families
to survive, since their livelihoods are dependent on agriculture.
This adaptation is inevitable and will add a cost to the national economy and households. To
successfully calculate this there is a need for proper planning and costing of adaptation
strategies at household, community and national level. Currently, the exact costs of
adaptation are not yet known hence this study was undertaken to investigate what
adaptation measures are currently available in the maize subsector in Chikhwawa District in
the Lower Shire Valley of Malawi and how much it will cost at household, community and
national level to continue to carry out such activities. The calculation is based on climate
projections that are likely to happen in Chikhwawa in the next 50 years.
The study revealed that communities are already coping with climate change through a
number of strategies including: use of early and drought-resistant varieties, irrigation
systems, selling of assets, winter cropping and diversification. Regarding climate projections,
it is expected that the temperatures in Chikhwawa will increase by 3oC by 2065, which will
translate into having more days in a month with a mean temperature of above 32oC. It is also
expected that drier conditions will prevail in the future (2046 - 2065).
In terms of costs, Chikhwawa will require about US$55,034,932 (over five years) in the
maize subsector to adapt to climate change. The results of the study suggest that
communities and government should start planning for the subsector bearing in mind the
likely scenarios. The study recommends that research into drought-resistant varieties,
investment in extension and training, as well as investment in irrigation should be
undertaken.
