Abstract. Aquaculture sub-sector is the largest contributor to the development of the fisheries sector in
Malaysia. Due to its potential and ability to enhance the national food production and resolve social problems
in Malaysia, the government allocated substantial funds and planned many programmes related to
aquaculture development. Climate change impact on aquaculture production is however uncontrollable and
damaging to the aquaculture growth. This study is carried out with the objective of identifying the
relationship between production, socio-economic and climate change risks in the aquaculture sector in
Sarawak, East Malaysia. This research was conducted on 249 aquaculture ponds and cages farmers in
Sarawak. To determine the relationship between all factors, cross-sectional multiple linear regression was
employed by using socioeconomic and climate risks data. Socio-economic factors such as number of family
members, variable cost and technology usage was found to significantly influence the aquaculture production.
Hence, bivariate analysis was employed to indicate the relationship between volumes of annual aquaculture
production with all climate change risks factors. The results revealed that increase of climate change risks
events have low and significant relationship with decrease in aquaculture productivity. In addition, the
qualitative information from the interviews did verify that decrease of dissolved oxygen in water, flood and
drought events were common production risks to aquaculture in Sarawak. This study suggests adaptation and
mitigation strategies need to be taken immediately to overcome the problem of climate change risks that may
be increasing in the future.
Keywords: climate change, risk, socio-economic, production, aquaculture growth.
1. Aquaculture Sector Growth in Malaysia
Aquaculture sector is one of the important sub-sectors in agricultural development in Malaysia. The
sector is still developing compared to such sector in neighboring countries like Thailand and China.
Aquaculture sector had been developed since 1920’s in Peninsular Malaysia. It started off with the
freshwater aquaculture and then brackish water aquaculture in the late 1930. While in Sabah and Sarawak
(East Malaysia), the aquaculture sector had only started to grow in the early 1990’s. Currently, there are
three practices of Malaysia’s aquaculture; the fresh water, brackish water and marine aquaculture.
The physical and financial drivers are two important aspects that have enhanced the competitiveness of
aquaculture sector development in Malaysia. From 1998 to 2010, the aquaculture production in Malaysia has
increased from 133,062 tonnes (3.9% of growth) to 500,000 tonnes (36.6% of growth). Starting from the
year 2003, a lot of programmes have been announced and commenced by the government to enhance the
potential of this sub-sector. The government invested and allocated a huge fund in order to improve and built
good facilities especially in aquaculture industrial zone area. The underlying reasons are due to the important
contribution of aquaculture sector in increasing national food production and to resolve the insufficient
marine fisheries landings and optimal exploitation of marine fish (Malaysia, 2003; Malaysia, 2011). The
contribution of aquaculture sector to Malaysia’s GDP shows a positive improvement within the years.
Aquaculture sector has contributed 0.283 in production value as percent of GDP in 2003 (Lungren et. al.,
