Abstract

Lake Singkarak is a livelihood source for people who live on the banks, especially for fishing activities. Unfortunately, this fishing sector shows a decline in fish catches since 1996 and significantly in 2007-2016. This paper presents the results of a study that specifically reveals the current state of the biophysical and environmental conditions of Lake Singkarak and explores the types of fishermen's livelihood strategies in relation to access to their livelihood assets at the current biophysical and environmental conditions of Lake Singkarak. This research framework adopts the Sustainable Livelihood Framework by applying a calculation of the index value/ratio of each livelihood asset. The results of this study indicate that changes in the biophysical conditions and the environment of the lake have played a role in influencing access to fishermen's livelihood assets at the study site and have implications for decreasing sources of livelihood from the lake. It was found that presently there are 6 types of livelihood strategies that are carried out by fishermen to be able to fulfill their living needs, namely Type B: Fishermen who carry out fisheries intensification and extensification (6.12%), Type C: Fishermen who have diversified their economic activities either in agriculture or non-agriculture (34.69%) , Type E: Fishermen who carry out fisheries intensification and extensification and also diversification (44.9%), Type F: Fishermen who carry out intensification and extensification of fishing and also temporary migration (2.04%), Type G: Fishermen who diversified their economic activities also temporary migration (4, 08%) and Type H: Fishermen who carry out fishing intensification/extensification, diversification and also temporary migration (8.16%). In relation to access to livelihood assets, it turns out that human resource assets are the main assets that influence the alternative choices of fishermen's livelihood strategies. The alternative type of strategy for diversifying economic enterprises, both in agriculture and non-agriculture, is the most widely chosen option besides alternative intensification and extensification of fishing in lakes.

Abstract

Mangrove, as one of the most unique ecosystems, is a great natural resource potential with high productivity and biodiversity able to adapt to harsh areas between the sea and coast. Its destruction rate is very mild as it is estimated to 1% each year (Ong et al., 1991) and 0.7-3% per year (Pedleton et al., 2012). The destruction of mangrove is usually related with human population density (Alongi, 2002). Widespread mangrove destruction affects the loss of biodiversity and other resources and the functioning of the ecosystem. The huge potential of mangrove must be preserved by managing, maintaining and providing costs to protect and improve ecosystems. This study aims to measure Kuala Langsa community members’ willingness to pay for the preservation and repairationof degrading mangrove. To achieve this goal, Contingent valuation methods was used in this study. Of the 131 respondents involved in this study, 112 or 85.496%  are willing to pay for the preservation of mangrove. While those unwilling to pay account for 19 or 4.504% . WTP with the households 669 earned by  is Rp 18,821,512,200/month or Rp 225,858,146,400/year.

Abstract

This study was aimed to analyze the physiological characteristics including respiratory rate, rectal temperature, and heterophil-lymphocyte (H:L) ratio of Sumatra’s organic chicken (SOC) that was raised in cool and hot climate regions. One-hundred-and-eighty-seven male and female SOC aged about 6 months were taken from cool and hot climate regions in Sumatera Island. Regions with cool climate were represented by highlands in West Sumatera including the subdistrict of Tilatang Kamang, Canduang, and East Padang Panjang. Regions with hot climate were represented by lowlands in Riau Province including the subdistrict of Bunga Raya, Lirik, and East Kampar. Samples of SOC were collected from farmers where the distance of sampling was about 500 m. Measurements were taken on respiratory rate, rectal temperature, and heterophil-lymphocyte ratio. Data was analyzed by t-test. The result showed that the respiratory rates of SOC in hot climate regions were higher than the ones in cool climate regions, the rectal temperatures of SOC in hot climate regions were lower than the ones in cool climate regions and there was no difference between the Heterophil:Lymphocyte ratio of SOC in hot climate and in cool climate regions.

Abstract

Population of Bilih Fish (Mystacoleucus padangensis) in Singkarak Lake has decreased as the effect of intensive exploitation and changes in water use function. Many appropriate works have been conducted for the fish conservation. One of them is introducing Bilih fish population to a new habitat,  Toba Lake. After nine years of releasing the fish, there was a hypothesis that these fish had undergone some changes on their morphology compared to their original population in Singkarak Lake. The changes could occure in some morphological characters and also the increase or decrease of their growth. This study was aimed at comparing morphology characters between Bilih fish introduced to Toba Lake with the original population in Singkarak Lake. Survey method was used and 400 samples of fish were taken from each Singkarak and Toba Lakes.  Parameters measured were 29 morphological characters. Data were analyzed using Mann Whitney U Test with SPSS 22. The results showed that 27 morphological characters of introduced fish had changed. Characters that had not changed were dorsal fin (anterior end)-anal fin distance (DFAF) and preanal distance (PD). Population of Bilih fish in Toba Lake might keep changing in the process of morphological character differentiation as long as environment factors still support the life of Bilih fish.

Abstract

In 2008, the Government of Ghana introduced a national fertiliser subsidy programme to promote the production of cereals in the country. Documented evidence of the impact of the programme, factors affecting participation, and the perceptions of farmers about its effectiveness remains scanty and hard to find. This study therefore sought to investigate the factors affecting participation in the subsidy programme as well as farmers’ perceptions about its effectiveness using data from a cross-section of 300 farm households in northern Ghana. The study employed a probit model to assess the factors affecting participation in the subsidy programme while descriptive statistics were used to present the findings on farmers’ perceptions. The results indicated that participation in the subsidy programme is significantly influenced by educational status and farming experience of the household head, contact with agricultural extension agents, herd size, degree of specialisation in rice production, use of farm mechanisation and location of the farm. Furthermore, farmers perceived the subsidy programme to be ineffective in terms of timeliness, availability and distribution of subsidised fertiliser, access to coupons (vouchers), and distance to fertiliser depots. The findings underscore the need to ensure adequate and timely supply of subsidised fertiliser, improve communication on the availability of both fertiliser coupons and subsidised fertiliser, as well as increase in the number of extension workers to enhance the effectiveness of the subsidy programme.
