There are four goals to this study. The first is to investigate the diet of prehistoric dogs (Canis familiaris) in the Northeast region of North America using stable isotope analysis. The second goal of this study is to generate independent data concerning the presence or absence of C4 resources, such as maize, in the diets of dogs. Third, this study investigates the use of dog bone as a proxy for human bone in studies assessing the presence of C4 resources at archaeological sites. The fourth goal of this study is to provide a check on existing interpretations of the material, macro- and micro-botanical records as it concerns the presence or absence of C4 resources at the sites involved in this study. Stable isotope analysis is a science that allows the measuring of the abundance ratio of two stable isotopes of a particular element. Stable isotope analysis can differentiate C4 and C3 plants, as well as terrestrial and marine resources in material such as bone where the chemistry of diet becomes recorded. Given the importance of C4 plants to many prehistoric populations, in the absence of direct evidence identifying their presence at archaeological sites, an alternate method for identification is needed. Maize played an important role in changing human behaviors during prehistory including: decisions to increase sedentism, abuse of power structures, and stratification of gender roles within human populations. Additionally, an overall decrease in health is seen in prehistoric populations who focused their subsistence practices on maize. Dogs were chosen as the focus of this study because related research suggests that their diet tends to mimic human diet. Prehistoric dogs were scavengers, but they were also intentionally fed companions. The suggestion that dog diet in some way mimics human diet means that stable isotope ratios from their bone will reflect the type of resources available for consumption by their human counterparts. As such, this investigation may also indirectly inform on the diets of the American Indian inhabitants of the settlements in which these dog remains originate. Thirty samples of dog bone, dating from the Early Ceramic Period, ca. 3000 B.P. to the Late Woodland and Early Historic Period, were obtained from museum and personal collections, and from ongoing archaeological excavations throughout the Northeast region of North America. Stable isotope analysis was conducted at Notre Dame's Center for Environmental Science and Technology. The results of this analysis indicates that these prehistoric dogs consumed the types of resources represented in the archaeological record with one important exception: consumption of C4 resources, possibly maize, was occurring at several sites where no other evidence of C4 exploitation exists. Of the dogs sampled ten were from pre-agricultural sites in Maine and their stable isotope ratios indicated a diet of marine and terrestrial resources. Nineteen dogs were excavated from components dating to the Late Woodland or Historic Period. During the Late Woodland and Historic Period the C4 plant maize was exploited by many human groups in the study region. Interpretation based on stable isotopes from bone collagen indicates that six of these dogs had isotopic signatures within the range of significant C4 resource consumption. Stable isotope ratios from the remaining dogs indicate a smaller contribution of C4 resources to diet. According to 13C ratios from carbonate three dogs, two from New Jersey (DB2, DB8) and one from Maryland (DB11), had a significant C4 plant component to their diet. The remaining Late Woodland and Historic period dogs most likely consumed minor amounts of C4 resources. In addition to identifying C4 resources in the diet of dogs, the value of assessing isotope data from both collagen and carbonate is investigated. The sample size for this study was small in comparison to the size of the region assessed. Despite the small sample size, this analysis contributes to our knowledge of past dog and human subsistence patterns. Our understanding of the utility of stable isotope studies of human companion species has also expanded. In addition to investigating the presence of C4 resources in the diet of prehistoric dogs, this research provides an alternate line of inquiry to re-assess current interpretations, especially in areas where direct evidence of isotopically identifiable C4 plants, such as maize are currently lacking. The results of this study are applicable first and foremost to the consumption patterns of the individual animals sampled. However, that these dogs were consuming particular resources provides at least a clue of what was under consideration by their human counterparts. / Anthropology

The original Yukpa are an indigenous community who have inhabited the lands of the Sierra de Perij a (mountain range of Perij a) in Venezuela since prehistoric times. The sovereignty of the Yukpa on their ancestral territories was protected from non-indigenous people until the arrival of Spanish Capuchin missionaries during the seventeenth century. The presence of the Capuchin missionaries furthered the entrance of non-indigenous people, who explored the area and discovered the fertility of the soil and a rich variety of natural resources. In the 1930s, ranch owners started the progressive occupation of Yukpas' ancestral lands, taking advantage of the Venezuelan government's indi erence to indigenous communities. The Yukpa started to resist the ranch owners. In retaliation, ranch owners responded with violence to intimidate and expel the Yukpa from what they claimed to be their property. The Yukpa have also been harassed by insurgent Colombian groups and drug dealers, who nd the Sierra de Perij a an ideal place to cultivate marijuana and opium poppy owers. To avoid the violence in the Sierra de Perij a, a signi cant number of Yukpa moved during the eighties to the city of Maracaibo in northwestern Venezuela. These displaced Yukpa have settled in lots located in the vicinities of the Hospital General del Sur, in Maracaibo, where they continue to live. For many indigenous communities, land and culture are interdependent. Land represents for many indigenous people their origin and continuity. Some authors claim that the forced displacement to areas distinct from their place of origin may disrupt the continuity of traditions which are the essence of their culture (Maybury-Lewis 2001:31; UNESCO 2009:207). This study examines ethnographically the Yukpa settled in Maracaibo in order to identify the extent to which the involuntary displacement from their ancestral territories has a ected their autochthonous land-based culture. Furthermore, this study provides a biographic pro le of the Yukpa settled in Maracaibo along with a discussion of their current needs, and some recommendations for further studies / Anthropology and Archaeology / M.A. (Anthropology)

This thesis focuses on two extreme weather years in 1867-1868 that led to crop failure and subsistence crisis in parts of Sweden. Specifically it focus on Gävleborgs County and one parish, Hanebo Parish, in south west Hälsingland. The study presents contemporary examples from original sources on the national, regional and local level and one secondary source. With a qualitative approach, the study investigates the social impacts of sudden extreme weather and following harvest failure and assess signs of a possible subsistence crisis on regional and local level in the years of 1867-68. The empirics are analyzed trough demographic methodology often used to evaluate ”famine-like” situations, theories on famine and its causes and the three concepts: vulnerability, resilience and exchange entitlement. The result of the study shows a subsistence crisis in Gävleborg county and Hanebo Parish, in the years of 1867-68. These indications included poor harvest, demographic impact on parochial level and visible mitigating strategies for coping with the situation. Social hierarchies which are making impact on attitudes within the contemporary context of crisis are also discovered in the empiric material. The study also shows that state incentives and publically organised incentives can mitigate disaster both over short and long term.

Thesis (PhD)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: South Africa is rich in biodiversity among which are semi-domesticated vegetable species which are known as wild or indigenous vegetables. These wild indigenous vegetables have been reported to be good in nutritional qualities such as macro and micronutrients. However, there is still a high prevalence of malnutrition; especially micronutrient deficiencies among low or marginal income bracket of the population. The use of indigenous vegetables has been proposed as part of the solutions to the problems of micronutrient malnutrition among these populations. Indigenous vegetables are an important source of food in the maize based subsistence farming sector of rural South Africa. Their main role is as relish as they are used as an accompaniment for staple cereal based diets. They are also generally reported to be rich in micronutrients. Although they may be consumed in small quantities, they influence the intake of cereal staples, manage hunger and play a central role in household food security for the poorer rural groups. Mixing several indigenous vegetables species in one meal contributes to dietary diversity in terms of more vegetable types as well as in terms of choice of relish. For some very poor families indigenous vegetables are substitutes for some food crops. The seasonal occurrence of these vegetables leaves many families without a food source during the off-season. Indigenous vegetables increase agro-biodiversity at the household level. This agro-biodiversity helps in buffering against the accumulation and multiplication of pests and diseases and provides important cover for the soil. Further research on agronomic, social and economic dimensions is required to understand the roles of IV in subsistence farming systems in South Africa. The survey study revealed that indigenous vegetables were important in the diets of most rural people in the study area. They were consumed as relish although they were not being cultivated. Their method of acquisition was gathering from homesteads and the wild. These vegetables were also believed to be medicinal. The local naming of wild vegetables varied among villages in the same district such that a vegetable in one village was assigned to a different species of vegetable in another village. They were reportedly abundant during summer and there was a decrease in availability off-season leaving vulnerable people who rely on them with a food shortage. The utilisation of wild vegetables among South Africans is reported to be declining due to over reliance on introduced temperate species. Efforts to domesticate and cultivate wild vegetables could be hampered by several factors including seed dormancy and premature flowering. In this present study dormancy was observed in C. olitorius. The response of wild genotypes of C. olitorius with different seed sizes to various dry heat and hot water treatments was evaluated. Steeping seeds in boiling water (95oC) for ten seconds and soaking seeds in a hot water bath at 80oC for ten minutes resulted in the highest response to germination in this species. The study also recorded significant interactions between heat treatment and seed sizes. We concluded that C. olitorius seeds of different sizes require diverse durations of exposure to heat treatment methods to break dormancy caused by an impermeable seed coat. Cleome gynandra is another species that is consumed as a vegetable in various parts of the world including Africa. The plant is also used as a medicinal herb for the treatment of various human diseases. Among the wild vegetables, C. gynandra has been reported to flower prematurely, a phenomenon known as bolting and common in many vegetable crops. Premature flowering (bolting) can be as a response to temperature extremes and photoperiod and affects many other leafy vegetables such as lettuce (Lactuca sativa), spinach (Spinacea oleracea) and mustard rape (Brassica juncea). Bolting leads to production losses in leaf vegetable crops as they flower before they have produced an economic yield. The removal of flowers and nitrogen application resulted in significant increases in the fresh and dry weight of cleome leaves. Removal of flowers resulted in a 46% increase in fresh weight of leaves. The observed positive response of leaf yield to removal of flowers offers a possible way to deal with the problem of bolting. The continuous removal of the flowers leads to increased utilisable leaf yield. The application of incremental amounts of nitrogen top dressing results in increased leaf yield in C. gynandra. The response of selected indigenous vegetables (Corchorus olitorius and Amaranthus cruentus) to micronutrients added to the soil was compared with the response of a reference crop; Swiss chard (Beta vulgaris var. cicla). For all the levels of micronutrients applied, Swiss chard accumulated Cu, Zn and Mn in the leaves at significantly (p<0.01) higher concentrations than the wild vegetables. Variations between the vegetables in the micronutrients were greater for Zn (72–363 ppm) and Mn (97.9–285.9 ppm) for Cu (8.8–14 ppm). C. olitorius had the least capacity to concentrate Mn and Zn in the leaf, which suggested that this vegetable is a less attractive candidate for agronomic bio-fortification of these elements. However, C. olitorius accumulated Fe at a significantly higher concentration (327 ppm) in the leaves than did Amaranthus (222 ppm) or Swiss chard (295 ppm). Sulphur as a macronutrient varied little in the plant species tested. The mean S concentration in the leaves ranged from 0.26% in C. olitorius to 0.34% in Amaranthus cruentus and Swiss chard. We concluded that the different vegetables have different abilities to take up Cu and Zn in the order Swiss chard > Amaranthus > Corchorus, and that they responded to micronutrients added to the soil but only up to certain limits of supplementation. The results from this current study seem to contradict the belief that wild vegetables have the inherent ability to concentrate mineral micronutrients in their tissue. Factors such as environment, anti-nutrients, dietary diversity, plant parts, plant age, and varieties result in differences in reported nutritional composition of indigenous vegetables. Post-harvest handling, storage, cooking and preservation also alter the composition. The need to optimise protocols for each vegetable type and for different laboratories makes analysis expensive. Equipment and methods of analysis are varied and may not be comparable, making it difficult to generalise on the composition of these vegetables. The Agricultural Research Council of South Africa and other stake holders are conducting studies on some aspects of these vegetables. There are still many information gaps regarding many aspects of these vegetables which require research attention. These include; the selection and improvement of genotypes, seed biology and germination studies, agronomic (population, fertiliser, crop mixtures) studies and phyto-chemical evaluation of these important species in order to encourage the overall use of these important indigenous resources. Finally, there is need to promote their increased utilisation. / AFRIKAANSE OPSOMMING: Suid- Afrika is ryk aan biodiversiteit waaronder half-mak groente spesies, wat as wilde of inheemse groente bekend is, voorkom. Hierdie wilde inheemse groente is aangedui om goed in voedingswaarde te wees met voldoende makro-en mikrovoedingstowwe. Daar is egter nogsteeds 'n hoë voorkoms van wanvoeding, veral tekorte aan mikronutriënte onder die lae of marginale inkomstegroep van die bevolking. Die gebruik van inheemse groente word voorgestel as deel van die oplossing van die probleem van wanvoeding onder hierdie bevolkings. Inheemse groente is 'n belangrike bron van voedsel in die mielie gebaseerde bestaansboerdery sektor van landelike Suid-Afrika. Hul vernaamste rol is as smoor waar dit gebruik word tesame met stapelvoedsel in ʼn graan-gebaseerde dieet. Hierdie groentes was oor die algemeen ook aangedui om ryk te wees in mikrovoedingstowwe. Hoewel hulle verteer kan word in klein hoeveelhede, beïnvloed hulle die inname van graan stapelvoedsel, en speel 'n sentrale rol in huishoudelike voedselsekuriteit vir die armer landelike groepe. Vermenging van verskeie inheemse groente spesies in een maaltyd dra by tot die dieet diversiteit in terme van meer groentesoorte sowel as in terme van die keuse van smaak. Vir 'n paar baie arm gesinne is inheemse groentes die plaasvervanger vir gewone groente gewasse. Die seisoenale voorkoms van hierdie groente laat baie gesinne sonder 'n bron van voedsel gedurende die af-seisoen. Inheemse groente verhoog landbou-biodiversiteit op ʼn huishoudelike vlak . Hierdie landbou-biodiversiteit help buffer teen die opbou en vermeerdering van peste en siektes en bied belangrike dekking vir die grond. Verdere navorsing op akkerbou-, maatskaplike en ekonomiese aspekte is nodig om die rolle van inheemse groentes in bestaansboerdery in Suid-Afrika te verstaan. Die studie opname het getoon dat inheemse groente belangrik was in die dieet van die meeste mense van die platteland in die studie area. Hierdie groentes was gebruik as smoor hoewel hulle nie gekweek word nie. Hul metode van verkryging is deur dit te versamel van huise en die natuur. Die groentes word ook as medisinaal beskou. Die plaaslike benaming van wilde groente het gewissel tussen dorpe in dieselfde distrik, tot so 'n mate dat die benaming van groente tussen dorpe verskil. Hulle was na bewering volop in die somer, en daar was 'n afname in die beskikbaarheid af-seisoen, wat kwesbare mense, wat staatmaak op hul voorkoms, met 'n tekort aan kos laat. Die benutting van wilde groente onder Suid-Afrikaners daal as gevolg van die afhanklikheid in nuwe spsies. Pogings om te mak en wilde groente te kweek, kan belemmer word deur verskeie faktore, insluitend saaddormansie en voortydige blom. In hierdie studie was dormansie waargeneem in C. olitorius. Die reaksie van wilde genotipes van C. olitorius met verskillende saad groottes op verskeie droë hitte en warm water behandelings, was geëvalueer. Sade was geweek in kookwater ( 95oC ) vir tien sekondes en ander in 'n warm water bad by 80oC vir tien minute, en het gelei tot die hoogste reaksie op ontkieming in hierdie spesie. Die studie het ook belangrike interaksies tussen hitte behandeling en saad groottes getoon. Ons het tot die gevolgtrekking gekom dat C. olitorius sade van verskillende groottes diverse duur van blootstelling vereis en ook so m.b.t. die ondeurdringbare saadhuid. Cleome gynandra is nog 'n spesie wat as 'n groente in verskeie dele van die wêreld, insluitend Afrika verbruik word. Die plant word ook gebruik as 'n medisinale plant vir die behandeling van verskeie siektes van die mens. Onder die wilde groente, was C. gynandra aangedui om vroeg te blom, 'n verskynsel wat bekend staan as “bolting” en is algemeen in baie groente gewasse. Voortydige blom (vas) kan wees as 'n reaksie op die temperatuur uiterstes en fotoperiode en raak ook baie ander groen groente soos blaarslaai (Lactuca sativa) , spinasie (Spinacea oleracea) en mosterd (Brassica juncea ) . “Bolting” lei ook tot produksie verliese in blaar groentegewasse as hulle blom voordat hulle 'n ekonomiese opbrengs opgelewer het. Die verwydering van blomme en stikstof toediening het gelei tot 'n aansienlike toename in die vars en droë gewig van Cleome blare. Verwydering van blomme het gelei tot 'n toename van 46% in vars gewig van die blare. Die waargenome positiewe reaksie van die blaar opbrengs deur verwydering van blomme bied 'n moontlike manier om die “bolting” probleem te hanteer. Die voortdurende verwydering van die blomme lei tot verhoogde bruikbare blaar opbrengs. Die toepassing van toenemende stikstof topbemesting het verhoogde blaar opbrengs in C. gynandra tot gevolg. Die reaksie van geselekteerde inheemse groente (Corchorus olitorius en Amaranthus spp ) met mikrovoedingstowwe toegevoeg tot die grond, is in vergelyk met die reaksie van 'n verwysings gewas; spinasiebeet (Beta vulgaris var cicla . ). Vir al die vlakke van mikronutriente toegepas, was die spinasiebeet opgehoopte Cu , Zn en Mn in die blare, in beduidend (p <0.01 ) hoër konsentrasies as die wilde groente.

Agriculture forms the livelihood basis of several billion people around the world. Despite the increasing trend for rural to urban migration the problems associated with poverty are expected to remain predominantly rural for some time into the future. The challenges associated with rural poverty are particularly important in South Africa where the remaining effects of the oppressive apartheid regime are still vividly evident. The rural population are often stranded in areas of stagnant economic growth and minimal employment opportunities further compounded by low levels of education. The livelihoods of these rural communities, in the former homelands, are often confined to a heavy reliance on remittance incomes and agriculture. However, in the recent past the level of agricultural activity in these rural homelands appears to be declining. This has direct implications for the development agenda in these rural areas. This study is an examination of the various dynamics which have affected the subsistence agriculture sector within a specific community in the former homeland of KwaZulu in Southern KwaZulu-Natal. The responses of 12 respondents, representing independent households, were recorded along with four purpositive interviews with relevant role players in the agricultural sector and in the rural community. The responses shed some light on the multifaceted dynamics which have played an important role in how individual households and the community at large make livelihood choices and how subsistence agriculture fits into these decisions. An increasing reliance on money as the basis of livelihood decisions is resulting in the reliance on agriculture shifting away from a central foundation of household livelihood towards a more supplementary form of food source and risk diversion. Shifting cultural norms have resulted in women and the youth becoming less involved in farming practices in general, which may have been influenced by the expansion of social grants into the rural communities. The changes in dynamics which influence local community and household livelihood decisions are important to consider when determining a possible development initiative in these rural areas. / Thesis (M.Dev.Studies)-University of KwaZulu-Natal, Durban, 2012.

The aim of this dissertation was to analyse the effect of socio-economic factors on poverty in Nyakallong. Nyakallong is a former Black township in the Free State Province of South Africa. The effect of the socio economic factors on poverty was analysed using an econometric model. The analysis was based on data collected by the researcher and three fieldworkers who conducted a survey of 412 households in Nyakallong in 2009. To calculate poverty rates and the effect of socio-economic factors, data relating to the area was used. Poverty was defined and then measured for the township, and the profile of both the whole and the poor population was determined. The following poverty lines are used in South Africa – PDL, MSL, MLL, SLL, HSL and HEL. The HSL, which is defined as an estimate of the theoretical income needed by an individual household to maintain a defined minimum level of health and decency in the short term, was used as a measure of poverty in the area. The headcount index, poverty gap ratio and the dependency ratio were also used to measure poverty. The headcount index was found to be 0.472 for Nyakallong, meaning that 47.2% of all household’s income is below their respective poverty line. Poverty rate in Nyakallong was found to be 48.5% which is almost similar to the poverty rate of 49.1% for the Free State province, while poverty rate in Kwakwatsi was found to be 62.1%. The analysis of the sources of income of the poor showed that government grants constitute 64% of household income, with the old state pension grant alone contributing 16% to household income for a poor family. In Kwakwatsi, government grants contributed 38.4% of poor household’s income, with the old state pension grant having contributed 40.6%. On average, the whole population has a monthly income of R2 938, 35 compared to R1 140 which is received by the poor population; while in Kwakwatsi, the poor population received a monthly income of R688 and the whole population received an average of R1401.01. The expenditure patterns for the whole sampled population show that 39.7% of household income goes to buying food, compared to 44.3% for the poor sampled population of Nyakallong. In Kwakwatsi, poor population spent 49.2% of income on food and the whole population spent 33.4%. In Nyakallong, 50% of the whole population and 53% of the poor population was found to be economically inactive. In Kwakwatsi, 44% of the whole population and 56% of the poor population was found to be economically inactive. The unemployment rate of the poor in Nyakallong is 95.6% compared to 69.9% of the whole population. In Kwakwatsi 86.9% of the poor population and 79% of the whole population were unemployed. The dependency ratio was found to be 6 among the poor population and 2 for the whole population of Nyakallong, while in Kwakwatsi it was found to be 7 among the poor population and 4 among the whole population. The study analysed the socio-economic determinants of poverty in the area. The data was evaluated using hypothesis testing for statistical significance of the parameters. It was established that there is a positive relationship between education and the poverty gap ratio although it is statistically insignificant. It was also found that there is an inverse relationship between employment and poverty ratio. This complies with theory. The results also showed a positive relationship between household expenditure and the poverty gap – this is what was expected, because expenditure is the reduction of resources. On gender, the results confirm the generally held hypothesis that female headed households are poorer compared to their male counterparts. The results show that poverty is high among female headed households compared to male headed households. Household size was measured by the number of people staying in a given house. The household size was found to range from one to eleven members per household. The average household size was found to be 4.2 in Nyakallong, 3.9% in Kwakwatsi and 3.4% in the Free State. Household size is an important variable in determining poverty – increasing the household size by 10% is likely to increase the poverty gap of the household by about 1%. This might seem not significant, but this is a result that must be noted and handled with caution. More people in households also mean more expenditure on food items, medical expenses, clothing and education. In order to reduce the level of poverty in Nyakallong, job creation and employment opportunities should be targeted. The nearby university of technology and FET College should inform learners at secondary schools about funds (NFSAS) available to help them in furthering their studies. Educators should also engage learners to realise the disadvantages of large household size. Large organisations such as ESCOM and Harmony Gold could help by means of skills development, especially among youth and females, in order to make them employable. Unemployment can also be reduced by putting back into operation the closed mine shaft and Allanridge Sanatorium hospital. A food garden community programme should be established in order to reduce the level of poverty. People who are involved should be trained on how to manage and develop the programme. / MCom, Economics, North-West University, Vaal Triangle Campus, 2012

Ce travail à pour but de déterminer le mode d’acquisition des ressources carnées par les groupes d’hominidés au cours du Paléolithique inférieur en Europe. La présence du genre Homo en Europe, antérieur à l’épisode paléomagnétique de Jaramillo est attestée dans plusieurs sites archéologiques. Cette dispersion hors d’Afrique est signalée par des industries lithiques appartenant à l’horizon culturel du Préoldowayen et par des restes squelettiques affiliés au genre Homo. Cette étude est axée sur l’analyse taphonomique et archéozoologique, de trois assemblages fauniques associés à une industrie du mode 1 (Barranco León, Fuente Nueva 3, la grotte du Vallonnet) et un assemblage associé à une industrie du mode 2 (la Caune de l’Arago). Les analyses permettent de comprendre les processus de formation de ces assemblages en contexte de plein air et en grotte et d’estimer la part des agents qui sont intervenus. L’implication des Hommes est attestée dans la modification des carcasses de grands mammifères. Des ossements présentent des stries, qui impliquent que les éclats étaient bien utilisés pour prélever la chair et une fracturation caractéristique, liée à l’éclatement des os par les outils aménagés. L’analyse des assemblages osseux révèle une variabilité des systèmes d’approvisionnement en matière carnée. La comparaison de ces accumulations formées en grotte et en plein air, apportent une meilleure compréhension des comportements de subsistances et permet de proposer un aperçu de la variabilité et de la chronologie des comportements alimentaires des Hommes en Europe méridionale pendant le Pléistocène inférieur et moyen. / The purpose of this work is determinated the mode of acquisition of the meat-based resources by the groups of hominids during the lower Palaeolithic in Europe. The presence of the genus Homo in Europe previous to the paleomagnetic Jaramillo event, is attested in several archeological sites. This dispersal outside Africa is indicated by litic industry belonging to the cultural horizon of Préoldowayen and by human fossils affiliated to genus Homo. This study is centred on taphonomical and zooarcheological analysis, of three faunal assemblages associated with a mode 1 industry (Barranco León, Fuente Nueva 3, the Vallonnet cave) and an assemblage associated with a mode 2 industry (Caune de l' Arago). Analyses allow to understand the processes formation of these assemblages in open air site and in cave, and to estimate the part of the agents who intervened. The implication of human is attested in the modification of the carcasses of big mammals. Bones present cutmarks which imply that flakes were used to discard flesh and a characteristic fracturation connected to the percussion of bones by stones tools. The analysis of the bones assemblages reveals a variability of the systems of supply in meat-based subject. The comparison of theses accumulations, bring a better understanding of the subsistences behavior and allows to propose an outline of the variability and the chronology of the eating habits of the Paleolitic People in Southern Europe during Lower and Middle Pleistocene.

This thesis addresses food insecurity from an Indigenous fisheries lens and presents a conceptual model by integrating three different but inter-related domains (ecological, cultural, and business) that impact Indigenous food security. Under the broader umbrella of fisheries and food security, the thesis addresses four objectives: (i) to investigate the co-existence of commercial and subsistence fisheries, (ii) to assess food security among commercial and subsistence fishing households, (iii) to explore the meaning of traditional food by engaging Indigenous youth with an objective to revitalize culture, and (iv) to examine the role of the fisherman’s co-operative as a social enterprise to address community economic development. The study was conducted over a period of 14 months (from September 2013 to December 2014) in Norway House Cree Nation, northern Manitoba, Canada. Community members are engaged in both subsistence and commercial fishing. The two kinds of fisheries co-exist, and potential problems of overlap are handled by temporal separation; spatial separation; formal mechanism of monitoring of net ownership; and informal communication for conflict resolution consistent with Cree values. The study found that extensive sharing of fish and other traditional foods by commercial fishers reached almost half of the total population in the community and contributed to improving food security. I used a participatory research approach to engage Indigenous youth to explore the meaning of traditional food. Participants produced a collaborative artwork on the theme of “what traditional food means to you?” This art work functioned as a boundary object, initiating discussion about food security planning in the community. Norway House Fisherman’s Co-op operates as a social enterprise mainly because of fish sharing and its role in business diversification for community economic development. The Chief and Band Council requested an exploration of ways to add value to their existing commercial fisheries. Based on the findings, further development can rely on: (i) better use of existing fish resources, such as the by-catch, (ii) fishing related economic development, such as value-added fish products, and (iii) use of options regarding regulatory bodies, such as eco-certification. / February 2017

Le Sénégal est situé dans une zone soudano-sahélienne particulièrement exposée aux changements du climat, ce dernier rendant l’agriculture, activité principale du pays, précaire. La modification des conditions climatiques, en particulier depuis la fin des années 1960, a fortement affaibli le secteur agricole, majoritairement vivrier et pluvial. Face à l’importance de l’activité agraire vivrière du pays, il apparaît primordial de savoir comment les agriculteurs vivriers du Sénégal ont modifié ou prévoit modifier leurs pratiques en vue de satisfaire leurs besoins alimentaires dans un contexte de changement et de variabilité du climat. Cette étude a été effectuée au sein de la communauté rurale de Sessène selon une approche qualitative et à l’aide d’entretiens, de l’observation participante et d’analyse phénoménologique. Elle a permis de mettre en avant les caractéristiques générales des familles agraires et des exploitations de cette zone, de montrer comment les agriculteurs ont vécu le changement climatique et comment ils envisagent les prochaines années et enfin de discuter de leur capacité d’adaptation. Face au raccourcissement de la saison des pluies, à la diminution des précipitations, à l’intensification des évènements extrêmes et aux impacts de ces modifications sur l’environnement naturel, les agriculteurs vivriers adoptent des mesures aussi bien techniques que socio-économiques. / Senegal is located in a sudano-sahelian region vulnerable to climate change that renders agriculture, the country's main activity, precarious. In fact, changing climate conditions, particularly since the late 1960s, have considerably weakened the agricultural sector, which is mostly subsistence and pluvial in nature. Because of the importance of the country’s subsistence agriculture, it is imperative to know how subsistence farmers in Senegal have changed or will change their practices in order to satisfy their nutritional requirements in the context of climate change and variability. This study was undertaken in the rural community of Sessène using a qualitative approach composed on interviews, participant observation and phenomenological analysis. The research revealed the general characteristics of the agrarian families and farms, demonstrated how farmers dealt with climate change in the recent past and how they envisage doing so in the next few years, all aimed at contributing to a discussion of their adaptive capacity. In response to the shortening of the rainy season, the decrease in rainfall, the increased frequency of extreme events and the impacts of these changes on the natural environment, subsistence farmers are adopting both technical and socio-economic measures.

This dissertation is a cross-national, empirical study of human rights conditions in a dynamic international political economy. The scope of the examination covers 176 developed and developing countries from 1980 through 1993. Through evaluating the numerous theoretical aspects of human rights conceptualization, I draw upon Shue's framework and consider whether there are indeed "basic rights" and which rights should fit into this category. Further, I address the debate between those who claim that these rights are truly universal (applying to all nations and individuals) and those who argue that the validity of a moral right is relative to indigenous cultures. In a similar vein, I empirically investigate whether various human rights are interdependent and indivisible, as some scholars argue, or whether there are inherent trade-offs between various rights provisions. In going beyond the fixation on a single aspect of human rights, I broadly investigate subsistence rights, security rights and political and economic freedom. While these have previously been addressed separately, there are virtually no studies that consider them together and the subsequent linkages between them. Ultimately, a pooled time-series cross-section model is developed that moves beyond the traditional concentration on security rights (also know as integrity of the person rights) and focuses on the more controversial subsistence rights (also known as basic human needs). By addressing both subsistence and security rights, I consider whether certain aspects of the changing international political economy affect these two groups of rights in different ways. A further delineation is made between OECD and non-OECD countries. The primary international focus is on the effects of global integration and the end of the Cold War. Domestic explanations that are connected with globalization include economic freedom, income inequality and democratization. These variables are subjected to bivariate and multivariate hypothesis testing including bivariate correlations, analysis of variance, and multiple OLS regression with robust standard errors.
