| Abstract | Takeo is one of the most productive rice-producing provinces. Rice surplus from flood
recessibn rice cultivation has boosted Cambodia rice export. In recent years, increasing of
pesticides uses and decreasing fish availability suggest that this area faces environmental
degradation in the future. Introducing rice-fish culture into flood recession rice paddies can be
partial answer to the recent drastic decline of fish consumption and environmental
deterioration. The study was carried out iri Treang and Donkev Districts amount 120
households.
The study investigated the implications of all relevant factors such as physical,
biological, resources and socio-economic conditions that prevailed in the cmTent agricultural
systems. Furthermore, the study also tried to find out the economic viability of each main
enterprise within current farming systems.
Four major farming systems described in this study are: flood recession rice, livestock,
fish culture and wild fish capture systems. Results showed that the existing farming is ricebased
systems with average recession rice yield is about 4 t/ha and average gross margin
ranging from US$ 168.42/ha to US$ 251.27/ha. Farmers can not earn money from culture of
Pangasius spy and pig rising which gross margin from these two enterprises were - US$
11.22/100 m and -US$0.66/head respectively. However they were considered as saving
money for later use. Wild fish still play a significant role for households' consumption. On
average respondents consumed fish at 33. 75 kg/caput/year with an average eating frequency
of 25 days/month.
The most obvious constraints fear the farmers to introduce rice-fish culture are: lack of
social security (poaching), heavy use of pesticides and unsuitable soil in some areas due to
acid sulfate soil. Introduce rice-fish culture into flood recession rice area is a long-term
development strategy that requires extensive and interdisciplinary research both on-farm and
off-farm under close cooperation, co-ordination among various governmental institutions and
between governmental institutions and NGOs. |
