Vulnerability of Rain-fed Farmer in Lao PDR and
Thailand from Impact of Climate Change
Adaptation direction for rain-fed farmer Lao
PDR Increase total productivity by increasing
rice production by improving farming / crop
management method and to increase buffer in
coping capacity, probably through increasing
livestock and / or off-farm income.
Some adaptation options taken to cope with past
climate variability 1 Seek for off-farm
products e.g. products from natural source 2
Implement alternate crop 3 Increase buffer in
coping capacity, e.g. community based rice bank,
livestock

increasing extra income, perhaps to be higher
than non-vulnerable group in order to cope with
higher expenditure and to increase buffer in
coping capacity, probably through increasing cash
convertible livestock.

26
Vulnerability of Rain-fed Farmer in Lao PDR and
Thailand from Impact of Climate Change
Summary Climate change shows strong tendency
to have impact on rain-fed rice agriculture
system, particularly the increasing in magnitude
and frequency of extreme climate variability.
Rain-fed farmers livelihood would be affected
from the damage or reduction in rice production
due to climate impact. Engaging local
stakeholders to get better understanding on
current adaptation strategies evaluate whether
they would be sufficient to cope with future
climate impact or not.
27
Vulnerability of Rain-fed Farmer in Lao PDR and
Thailand from Impact of Climate Change
  • Project wrap-up plan Planning adaptation
    strategy evaluation
  • Some concerned issues site specific /
    limitation / feasibility
  • The threshold of natural system condition to
    sufficiently support community in compensating
    the lost in rice production of farmer in Lao PDR
  • Also degradation of the natural system as well
    as change in population to the threshold that
    such system may be overly exploited.
  • Economic condition in the city in Thailand to
    support excess labor from upcountry, who try to
    seek for extra income to support their livelihood
    when income from rice production is not
    sufficient.
  • Innovative new adaptation strategies to cope
    with the future vulnerability to climate change
    impact need to be developed
