Abstract

One of the effects of global climate change is the increasing sea level, which has resulted in higher intrusion of sea water to the mainland in the Mekong Delta region in Vietnam. This study specifically explores the impact of saline intrusion on the socio-economic life of farmers in this region. A socioeconomic survey was carried out in two provinces in the eastern and western regions of the Delta, namely the Kien Giang province in the West and the Tra Vinh Province in the East which represented two regions, each of which experienced different levels of saline intrusion. Data collection methods include secondary data collection, focused group discussions, expert interviews, key informant interviews and 280 household questionnaire surveys. Technically, saline intrusion has changed the farming system from rice culture to shrimp culture at both sides of the Delta. Because of the need for investment in shrimp culture, a group of farming communities with large capital quickly took the opportunity to move to intensive shrimp culture. Meanwhile, other groups of farmers who lack of capital, are only able to carry out traditional rice-shrimp culture by digging around their paddy field for shrimp pond, with lower economic outcomes from their rice and shrimp production. Weak social organizations in the community, making the impact of saline intrusion is only beneficial for a few groups of people.

Abstract

In a development perspective, small islands have limited economic access and opportunities, especially related to the economics of scale. Furthermore, the common problem such as climate change impact requires appropriate behavior of local inhabitant in order to survive in gaining to the economic access. Multi-ethnic society has different socio-cultural background that implies special characteristics and strategies to overcome climate change impacts. This study was conducted in Masalembu Island which consist of Madurese, Mandar, Bugis and Javanese ethnic. The aims of this study are to describe negative impact of climate change to the fisherman and to describe fisherman’s behavior for adapting climate changes. Theanalysis method is mixed method between the descriptive quantitative and qualitative analysis. The results show climate change causes fluctuating fish production, extending fishing ground to be more off-shore, uncertainty schedule for fishing and invasion from outer fisherman. Meanwhile, fishermen's behavior in overcoming the impacts of climate change consist of active response by Group of Fishermen, apply autonomous adaptation and apply adaptation behavior technologically, sociologically and regulatory. Based on these results, it is necessary to improve planned adaptation trough aquaculture, applying modern but friendlytechnology fishing gear and enhancing participation as well as cooperation among fisherman without ethnic consideration.

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.

Abstract

The Ministry of Agriculture has implemented the Rice Farming Insurance (RFI) Program in Indonesia since 2015 to protect farmers from possible loss of crop failure due to various potential disasters such as floods, drought, pests, etc. Although it has been immensely encouraged by the relevant field agencies, this RFI program was unsuccessful. The land area that follows the RFI program in Tanah Datar District decreased significantly from 1,061 Ha (2016) to about 150 Ha (2017), of the total target area of 2,300 Ha. This study is conducted to find factors that lead to decreased farmer participation in this RFI program, mainly by studying how the government has done the socialization process and how farmers' actual attitude towards this RFI program? By applying qualitative and quantitative approaches, this study obtained the empirical facts that the socialization process, done by relevant stakeholders, including government, private and community leaders, and farmers, not so intensified. The attitude of farmers to this program showed that, in the cognitive aspects, most farmers in all five categories still do not fully understand and confident about the RFI program. It is similar to their affective elements; most farmers in the five categories have not yet determined attitudes, whether they like or dislike the RFI program. Meanwhile, only in terms of their conative aspects, mostly farmers of all categories are eager to learn more and become the RFI program participant.

Abstract

The research was conducted on three small islands of the marine conservation area of West Sumatra, namely Kasiak Island, Bindalang Island, and Karabak Ketek Island from January to December 2016. This research aimed to study the variation of the biophysical character of the nesting habitat of the green turtle (Chelonia mydas L, 1758) by survey method, measurement, observation, and analysis. All data were analyzed using Main Component Analysis (PCA), Kruskal Wallis Test Analysis. Based on PCA analysis, the contribution of the main character is 43.28%. These results are supported by biophysical conditions of spawning habitats for green turtles on Karabak Ketek Island as an ideal island of spawning sites favored by green turtles compared to the location of Bindalang Island and Kasiak Island habitats. Kruskal Wallis analysis of Karabak Island rank; 11.90, with a chi-square value; 10.47, sig value 0.005 (5% -10%). This value shows the difference between the spawning habitat's biophysical character on the character of the coastal slope parameter (KP) is 9.60°. It is also the ideal slope value for the sandy beach habitat (PSe) and fine sandy beaches (PHA) as the central spawning location for green turtles in West Sumatra

Abstract

The medicinal properties of Pouteria campechiana fruit in Vietnam currently have not been studied much. This study was conducted to evaluate hydrolysis's effect on the carotenoid, tannin, and antioxidant activity through the correlation between IC50 and TPC values of Pouteria campechiana extract. This study examined hydrolysis conditions, such as enzyme type, enzyme concentration, temperature, and hydrolysis time. Experimental results showed that at pectinase enzyme concentration of 0.6 wt%, cellulase enzyme concentration of 0.6 wt%, at hydrolysis temperature of 600C, and 65 minutes for hydrolysis, the study found carotenoid of 115.14±4.14 (µg/g) and tannin of 45.88±2.37 (mgTAE/g)in the extract. IC50 value (7.82±0.21 mg/mL) and TPC content were highly correlated (R2=0.98). This study's results contributed to the provision of valuable scientific data on Pouteria campechiana fruit, especially for the food industry

Abstract

This study has been conceived with the basic objective to investigate the role played by industries in the East Godavari River Estuarine Ecosystem (EGREE) region to reduce the level of industrial pollution and other eco-friendly initiatives taken for eco-friendly and sustainable development. Effluent treatment systems prevalent in the majority of the studied industries are in working conditions. 57% of industries' effluent treatment plants are working conditions, 29% of the industries are using landing filling methods for disposal of agro-based waste. There is a strong common understanding among the EGREE region industries to lower the CO2 footprint by substituting coal consumption with bio-fuel. In some companies like ITC, biofuel consumption is 80%, and the remaining 20% is Coal. Government and policymakers have to make provision for industrial waste disposal, especially for small and medium enterprises (SME).  Waste transporting cost is high for SME. Effluent treatment plant (ETP) and sewage treatment plant (STP) conditions to be verified by the pollution control board periodically

Abstract

The study evaluated factors affecting the selection of agricultural farming models and advantages, difficulties, and opportunities in the implementation process to propose solutions to develop appropriate agricultural sustainable farming models. The study uses secondary and primary data through KIP interviews, focus group interviews, in-depth interviews, and farmer interviews. As a result, this study found education is an important factor affecting farmers in choosing their farming models and increasing agricultural production in their farmland. For most of the considered factors, the majority of Kinh people choose to evaluate the influence of the decision in choosing a farming model higher than another ethnic group (Khmer). Besides, the Khmer ethnic group accounts for a higher proportion of poor households (18.2%) than the Kinh group. Because of low economic conditions, decisions on agricultural production of Khmer ethnic groups are less assertive than that of the Kinh people. On the other hand, there is a serious shortage of water in the dry season in the highlands, cultivated mainly by rainwater, ethnic minority accounts for 53.36% of the whole commune population, educational level makes it difficult to apply modern techniques in production. Therefore, strengthening and mobilizing people, investing in building upland irrigation systems, and using effective land conversion are essential activities to be carried out to improve the efficiency of farming models to make sustainable agricultural production that can increase income and enhance the economic life of local people.
