2.3 Conceptual Framework
The invulnerability of coastal livelihood to the impact of climate change has been the hope for all sectors including fisheries sector, fisheries business,
government, and other relevant sectors. However, that hope is seemingly far- fetched, seeing the poverty in the research area. The poverty of this community is
strongly related to the ownership and the use of simple technology and the high dependency of fisheries sector on climate Indah Susilowati, 2004; Mayanggita
Kirana, 2008
The change of ecosystem caused by climate change affects the productivity of fisheries sector, mainly in the disaster prone areas where climate
change, storms, and abrasions can be found. These fishermen are vulnerable because they still have a lack of understanding about climate and weather
information which is provided by BMKG, and they still use traditional technique in predicting weather, making the output of production decrease. This causes their
bidding level lower. Therefore, economic valuation to frame adaptation and mitigation
strategies is needed. It is expected that the income of the people working in small scale fisheries sector and the fulfillment of needs of the coastal livelihood will
increase.
2.4 Hypothesis
Based on the research of Indah Susilowati 2010 en titled „Developing
Adaptation Strategies Due To Climate Change: with Special Reference to The Vulnerable Small Scale Fisheries Sector in Central Java
– Indonesia‟, small scale fisheries sector, which consists of fishers with 5
– 30 GT speed boat, was the most vulnerable sector to climate change in Java island. Their inability was caused by
their unawareness of the indicators of fishery vulnerability. Therefore, there should be a continuous empowerment of stakeholder that was competent, such as
academicsNGO, businessman, government, and community in general. Marine and Fisheries services, BMKG, local government, the department of industry, and
should immediately work together in the efforts of the empowerment of coastal livelihood. This research also stated that the co-management approach is a
promising approach in overcoming the impacts of climate change on fisheries sector.
E. Baran, N. Schwartz, Y. Kura 2008 also stated that most fisheries workers in Cambodia are very vulnerable to climate change. Adaptation and
mitigation strategies offered by the research are increasing the adaptation capacity in fisheries community by building infrastructure such as hydropower dam,
intensifying the fisheries sector, and building macroeconomics. Based on prior research and studies, the hypotheses of this research are:
1. The level of vulnerability of people in fisheries sector due to climate
change is still high. This is caused by the ignorance of the local fishermen
about the information given by BMKG and the traditional culture of
fishing in study area.
2. The climate change shifts the best season for fishing. Thus, the fishermen
would not be able to go fishing in the same season like they used to be which will decrease their productivity. Furthermore, climate change will
cause an additional length of trip and additional costsspending of
fishermen.

The definition of indicators of variables is as follows: 1.
Impact on production is impact of climate change towards the production of marine fisheries. It can be measured by changes in volume of catch,
length of trip, and spending or costs of fishermen. FAO, 2010
