3. Statement of the Problem
Agric. has been identified as the most severely
affected by dry spells & drought
These have presented new challenges to
smallholder farmers because they are
exogenous.
For example, about 1.1 million people were
reported to be food insecure due to unreliable
rainfall patterns (FEWS NET,2013).
4. Definition: Resilience
The ability of a system, community or society
exposed to hazards to resist, absorb,
accommodate and to recover from the effects of a
hazard in a timely and efficient manner, Phiri
(2010: 19)
The ability of the community, society or even a
household to “spring back” from a shock, UNDG
(Undated:38).
The amount of change a system can undergo and
still remain in the same state, Falkenmark and
Rockstrom (2009:94)
5. Objectives
Main objective:
To determine how prolonged dry spells and
droughts have affected the resilience of maize
farming households in Salima district.
Specific Objectives:
Determine factors that affect a household’s
resilience to dry spells and droughts in Chipoka EPA.
Determine the effect of drought resilience on the
welfare of farming households in Chipoka EPA
6. Methods
• Principal Components Analysis (PCA) used to
construct DRI
• Probit model used to identify determinants of
resilience
• Stochastic frontier approach used to determine
the effect of drought resilience on household
output (proxy with welfare)

14. Conclusions
62 percent are vulnerable to adverse effects
Mean DRI of -0.0857 is below threshold of 0
for a household to be considered resilient.
Determinants of resilience: age of Hh, Size of
Hh, Land and number of immediate family
members living outside household
Resilience had a +ve effect on Hh welfare
15. Policy Implications
Govt. & non-state actors working in Chipoka to
consider introducing productivity enhancing
technologies such as irrigation in the study
area.
Encourage farmers to diversify crop production
and participate in off-farm livelihood activities.
Target beneficiaries to food aid and other relief
programs.
