“…This study was conducted in East Java, Indonesia, which has experienced the climate change phenomena to a large extent. A study conducted by Kusuma, et al [42] claimed that the average sea surface temperature in East Java increased by 0.8 degrees Celsius from 2007 to 2016. Moreover, this province is predicted to face an increase in average annual temperature from 0.8 to 1.0 • C between 2020 and 2050; hence, it is relevant to the latest climatic era of the twentieth century [43].…”

The Impact of Climate Change Adaptation Strategies on Income and Food Security: Empirical Evidence from Small-Scale Fishers in Indonesia

2021

The impacts of climate change on marine capture fisheries have been observed in several studies. It is likely to have a substantial effect on fishers’ income and food security. This study aims to estimate the impact of adaptation strategies on fishers’ income and their household’s food security. Data were collected from small-scale fishers’ households, which own a fishing boat smaller or equal to five gross tonnages (GT). The study sites were the two coastal regions of Malang and Probolinggo in East Java, Indonesia, due to the meager socioeconomic resources caused by climate change. A probit regression model was used to determine the factors influencing the fishers’ adaptation. Propensity score matching (PSM) was applied to evaluate the impact of the adaptation strategies on income and food security. Food security was measured by food consumption score (FCS). The findings indicated that participation in the fishers’ group affected adaptation strategies significantly, and so did the access to credit and climate information. Also, PSM showed that the adaptation strategies had a positive and significant impact on fishers’ income and food security. Those who applied the adaptation strategies had a higher income and FCS than those who did not. This finding implies that the fishery sector’s adaptation strategies can have significant expansion outcome and reduce exposure to risks posed by climate change. Therefore, the arrangement of more climate change adaptation strategies should be promoted by the government for small-scale fishers in Indonesia.

“…Furthermore, fishing season depends on effort (Simbolon & Limbong, 2012) and also environmental conditions, such as Sea Surface Temperature (SST). The warm SST occurs in March in FMA 571 and 572 of the Indian Ocean (Kusuma et al, 2017).…”

Frigate tuna (Auxis thazard) is one of the major commercial tuna species, both in industrial and small scale fisheries, particularly in the waters off Western Sumatera. In Indonesia, A. thazard is a group of locally called “tongkol” together with A. rochei, Thunnus tonggol, and Euthynnus affinis. This study describes a preliminary examination of frigate tuna catch from purse seine off the coast of western Sumatera (FMA 572). The data were collected daily by an enumerator on the fish landing site from 2013 to 2017, including fishing gear, number of days at sea, catch, length, and weight of frigate tuna. The fishing ground coordinate data provided by the observer on board the vessel. General Linear Model (GLM) with gamma was applied in this study to standardize the CPUE by year, quarter, season, and GT as fixed variables. The results showed that the variation of CPUE was mostly influenced by year and quarter, while season and fleet size (GT) showed less impact on the catch. In general, even though the catch trend declines during the observation years, the population of frigate tuna off the coast of western Sumatera (FMA 572) were considered sustainable.

“…The temperature changes in waters, apart from being caused by the heat of the sun shining on the sea surface, are also influenced by surface currents, cloud conditions, horizontal and vertical exchange of water masses as well as the presence of upwelling [22]. In addition to the influence of monsoon winds, SST in Indonesian waters is influenced by global climate phenomena such as El Nino and Indian Ocean Dipole (IOD), especially in waters associated with the Indian Ocean [23][24][25], and in general the west monsoon is cooler than the east monsoon. The low SST value in the Southern Waters of Lombok Island is due to the direct connection with the Indian Ocean which is the most intensive upwelling area [26].…”

This research aims to observe the settlement of puerulus lobster larvae in the waters of Awang Bay in relation to the spatial and temporal fluctuations in aquatic environmental conditions. This research was conducted from August to October 2020 in the waters of Awang Bay, Lombok Island. The main data collected in this study is puerulus settlement,while the supporting data are physical, chemical and biological parameters of the waters. Observations of the aquatic environment are carried out in-situ, namely direct measurements in the field and analysis of satellite images. The collected data were analyzed by multiple regression analysis. The results showed that the distribution of sea surface temperature and chlorophyll-a in the waters of Awang Bay and its surroundings based on satellite imagery during August to October ranged from 25-32 °C and 0.1370 - 2.3532 mg/m3 respectively. Warm temperatures and chlorophyll-a are concentrated in coastal areas and are decreasing towards the offshore direction. The nine environmental parameters studied contained two parameters that significantly influenced individually on puerulus lobster settlement, namely the abundance of plankton and temperature. Meanwhile, brightness, current velocity, dissolved oxygen, salinity, pH, phosphate and nitrate had no significant effect. The significant relationship between plankton abundance and temperature and puerulus lobster settlement was due to plankton being the main food for larvae, and the sea water temperature was still relatively stable so that lobster seeds still survived and could support puerulus lobster settlement.
