This study aims to contribute to our understanding of how rice and fish availability
affect occupation and food security of people in the Lower Mekong Basin (LMB),
including Cambodia, Lao PDR, Thailand, and Vietnam. The study focuses on
subsistence and commercial fishers and farmers. The data obtained for my research are
from the first basin-wide survey conducted across the four countries using a common
methodology and timing in 2009. Results of the study show that the extent of
dependence of people on rice and fish availability for occupation, income, and food and
their resilient capacities varies greatly between strata and across study sites.
If both fish and rice decline at a common rate applicable to the whole LMB, cash income
of at least one of four strata in each site will easily fall below the poverty line of $1.00
per capita per day. Seen from the perspective of food, all strata of all sites will be
significantly affected if the availability of rice and fish decline. Altogether, fish and rice
account for more than 81% of the total daily calorie intake. With uneven distribution of
population by countries and varied social-ecological zones and livelihood activities,
impacts of changes in the rice and fish availability will not distribute evenly. If changes occur throughout the Mekong, the number of people impacted will be highest in
Vietnam, followed by Cambodia and Lao PDR. Thailand will be affected the least.
