Off the 1,572 km long coastline of Namibia lies known as the Benguela upwelling system, a very rich source of marine life supporting traditional and modern forms of fishery. Commercial fishing and fish processing is one of the fastest-growing sectors of the Namibian economy in terms of employment, export earnings, and contribution to GDP. The fishing industry has grown to the extent that it is currently Namibia's second biggest export earner of foreign currency after mining (90% of national output is marketed for export). In 2005, Namibia harvested about 552,164 tonnes of fish. The final value of processed products (export value) that year was around US$ 376.0 million. Besides the marine captured fisheries, Namibia also has a small but vibrant aquaculture sector. Inland captured fisheries exist in the north-east and north-west of Namibia where as commercial freshwater aquaculture of tilapia and catfish is also undertaken. The inland fisheries are mainly subsistence based and typically labour intensive, with low catch per unit effort. However the subsistence fisheries from these regions play a significant role in the lives of rural community. The domestic market for marine fish products is extremely limited due to the small size of the population (2 million). The fishing industry is a source of considerable employment for many Namibians. Huge potential to increase production exists in Namibia, unpolluted high quality marine waters, high natural primary productivity of the seawater, availability of inexpensive fish by-products from established fish processing sector for inclusion in wet aqua-feeds and well-established processing, packaging and marketing systems due to the marine capture fisheries that can be adopted for aquaculture purpose.

Dairy goat production continues to be a socially, economically and culturally important part of the livestock industry in North, Central and South America and the Caribbean islands. Goat milk, cheese and other dairy products offer consumers food products with nutritional, health and environmental benefits. In North America, Mexico produces the greatest volume of goat milk, but most is for family or local consumption that is typical of a mixed farming system adopted by subsistence farmers in dry areas. The United States is not yet a large global goat milk producer, but the sector has expanded rapidly, with dairy goat numbers doubling between 1997 and 2012. The number of dairy goats has also increased dramatically in Canada. Commercial farms are increasingly important, driven by rising demand for good quality and locally sourced goat cheese. In South America, Brazil has the most developed dairy goat industry that includes government assistance to small-scale producers and low-income households. As of 2017, FAO identified Haiti, Peru, Jamaica, and Bolivia as having important goat milk production in the Western Hemisphere. For subsistence goat producers in the Americas on marginal land without prior history of chemical usage, organic dairy goat production can be a viable alternative for income generation, with sufficient transportation, sanitation and marketing initiatives. Production efficiency, greenhouse gas emission, waste disposal, and animal welfare are important challenges for dairy goat producers in the Americas.

This study reviews recent shell midden studies in Korea. With more interest in biological materials, recent shell midden studies have attempted to reconstruct palaeoenvironment, and understand subsistence economy, the formation processes and function of sites and past culture. Especially, one of the major topics in prehistoric Korean shell midden studies is the transitional process from hunter-gatherer to farmer. To solve these questions related with shell middens, new sampling strategies and excavation techniques have been adopted. Analytical methods combined with scientifical technologies also have been introduced to shell middle studies. These methods indude stable isotope analyses(Oxygen isotope and Carbon and Nitrogen isotope analyses) and growth-line analysis, etc.

The entry of the logging industry in the once heavily forested riverine middle Agusan Valley where aboriginal Manobos live meant the entry of the material practice of wage labor into this out-of-the-way place. Wage labor converted the once relatively isolated, subsistence animist Manobos into laborers of the expanding capitalist regime. A symptom of modernity, this wage labor also accompanied the coming of Visayan settlers (also loggers paid by wage) who introduced indigenous Manobos the compadrazgo social relationship. This friendly relationship across ethnic identities legitimated social ties and is a social material practice represented in recent bilingual Manobo possession rituals where the Visayan spirit is incarnated along with Manobo spirits. To understand the idea behind spirit embodiment, I explore Manobo ritual as mimesis or poeisis. This representation is shaped by concrete material realities as much as these realities, in turn, are reconfigured by ritual practice. In the older Manobo cosmology, which is based on subsistence economy and dependent on the forest and rivers, individuals have an externalized self (as manifest in the idea of twin soul), in which the inner vital principle is co-extensive with a spirit double in cosmos. Manobos imitate the perceived workings of nature in ritual so as to control them in times of illnesses. In contrast, the mimesis of the Visayan spirit is based on a different political economic set up with its attendant asymmetrical interpersonal relationship. By symbolically representing the Visayan patron as friend, Manobos are able to negotiate the predicament of their subalternity in local modernity.

Soybean yellow mottle mosaic virus (SYMMV) and Soybean yellow common mosaic virus (SYCMV) were recently isolated in Korea, and it has not been reported how two viruses were dispersed in Korea. In 2012, we performed nationwide survey in subsistence soybean farming. Suspicious virus-infected infected leave were collected from the field and a total of 682 soybean tissue samples were assayed by RT-PCR using triplex primers detecting SYMMV, SYCMV, and Soybean mosaic virus (SMV). On hundred two samples showed SMV positive, and SYMMV and SYCMV were detected in 116 and 17 tissue samples, respectively. No sample showed double infection of SYMMV and SYCMV, but there were double infection tissues indicating two viruses positive of SMV plus SYMMV (5 tissue samples) and SMV plus SYCMV (1 tissue sample). Through this first subsistence soybean farming field survey, we assumed soybean viruses were originated from home seed production managed by farmer. Thus, in order to prevent possible seed transmission and further damage caused by virus transmission, virus-free commercial soybean seeds are recommended to be planted.

The Hmong people are one of the largest ethnic groups in Vietnam. They traditionally practice shifting cultivation for their daily subsistence. This group has a traditional governance system as well as strong clan and kinship relationships that occupy an important role in maintaining Hmong culture and livelihoods. The state's approval of the legitimate and statutory law for the Nature Reserve largely excluded local rights of access to and the use of natural resources. This study focusses on Hmong responses to the state interventions of the establishment of the Nature Reserve as well as forest land allocation. Based on Scott's contribution of Moral Economy (1976), the authors argue that local responses function as a 'risk-averter' against state intervention. Meanwhile, the intra and inter-ethnic relationships based on the 'subsistence ethic' help locals successfully mitigate state intervention. These findings help the state rethink their interventions, which have been constructed with very little respect for local differences or the desires of ethnic peoples. Furthermore, the main findings, which reveal that not only the intra-ethnic relationship but also the inter-ethnic relationship among ethnic minorities can play an important role in maintaining the Moral Economy, are expected to deepen the previous understanding on the Moral Economy, which has previously constrained its scope to the intra-ethnic relationship.

Absolute poverty is redefined as biological existence level poverty and relative poverty is also redefinded as 'the state that relatively insufficient compared to the specific society's average living standard under the condition that basic needs on the biological existence level has been satisfied.' Then absolute poverty and relative poverty lies on the same welfare continuum. Therefore these two can be regarded as one unified concept. Theoretical bottom line of poverty is the biological existence level and ceiling is average income. Poverty line for the social policy is to be drawn between ceiling and floor. Using these standard lines three poverty bands are categorized : minimum subsistence level, minimum decency level.

The purpose of this study is to explore the model and application for family life welfare service in Korea. In order to explore the characteristics of family life welfare service, the object, the extent and approach for family life welfare service is examined. The model for family life welfare service is constructed on the base of definition for family life welfare-subsistence of family life, personal formation and development, the creation of community culture-, family life cycle and demand for family life welfare service. Lastly, the contents and politic supports for family life welfare service are examined.

This research challenges the general notion of one-person households of the elderly during widowhood as impoverished, isolated, and vulnerable. Recognizing a high potential vulnerability, however, this research attempts to describe the diverse composition of one-person households of the elderly. For this purpose, relying on 2% sample data from the 2000 census, it examines regional distribution, socio-economic characteristics, and determinants of one-person households of the elderly during widowhood. Socio-economic characteristics of one-person households of the elderly differ by region. Jeju island is distinct in terms of sex and age distribution, and residence area of children. In general, rates of economic activity and self-subsistence are higher in provinces than in cities. Compared to the elderly living with family, the elderly living alone show high rates of economic activity, self-subsistence, and capability of physical activity. Results of logistic regression analysis of determinants of living arrangement are consistent with those of descriptive statistics. Those who are economically active and able to move around without assistance tend to live alone after the death of a spouse. Number of sons and living in an urban area are negatively associated with living alone, whereas females are more likely than males to live alone. According to the separate analysis by age, the positive effect of economic activity is greater in the oldest of the old than in other age groups. Those who possess high educational attainment tend to live alone when they are 80 and older, unlike other age groups. Based on these findings, this paper finds that one-person households of the elderly nay not always be the most vulnerable group, and are diverse in terms of socioeconomic characteristics.

In this paper, "Gyeonggi-Do household weekend travel survey" is used in order to analyze activity participation and travel behavior for the people who go to work on Saturday(workers) and those who do not go to work(non-workers). To find out causal relationship between activity participation and travel behavior, Structural Equation Models are developed. Examination of the causal relationship between activity participation and travel behavior identifies three stages. Firstly, subsistence activities and leisure activities are generated. Secondly, each activity participation produces trip volumes and travel times. Finally, the sum of travel times forms trip volumes. Looking into the activity participation stages for the workers, their subsistence activies have a tendency to take place first, and leisure activities usually follow. Non-workers generate more simple trip chains and most of their first stage activities are leisure related.
