In the last century, many mobile pastoralists have transitioned to more sedentary lifestyles. Mobile people can be both pushed into a more settled existence by environmental or political forces, or pulled by new economic opportunities. While researchers have examined the causes and consequences of growing sedentarization, few contemporary studies have examined the patterns of settlement among mobile groups who are shifting to sedentary lifestyles and how these patterns may be related to socio-economic outcomes. This research examines settlement site selection by using GIS and remote sensing techniques to quantify settlement patterns in four Maasai villages in northern Tanzania, exploring the environmental and infrastructure correlates of settlement locations. A subset of these geographic variables is used with social survey data for 111 Maasai households in the study site to test the hypothesis that settlement location impacts livelihood strategies and economic outcomes by creating and constraining access to important resources and infrastructure. Landscape level evaluation of settlement pat-terns show that certain soil types limit occupation and the potential for agricultural expansion in 30% of the study area. Settlement density and existing agriculture are also clustered in certain parts of the landscape. The spatial models support the hypothesis that proximity to roads and village centers plays an important role in shaping overall settlement patterns. However, models that combine these factors with environmental and geophysical elements show improved explanatory performance, suggesting that competing factors are at play in influencing settlement patterns. Spatial models also indicate that agricultural development may be limiting land available for settlement in some parts of the study area. Results of the household level outcomes are more ambiguous, with few relationships between geographic variables and household livestock holdings, land under cultivation, annual income. Rather, these factors are influenced largely by demographic variables such as household size, age of the household head, and asset allocation. However, there appears to be less income diversity in households more distant from permanent water sources. / Master of Science / Around the world, many people who traditionally have moved from place to place on a seasonal or annual basis have become much more settled, often no longer moving at all. These formally mobile people can be both pushed into a more settled existence by environmental or political forces, or drawn by new opportunities presented by being more settled. While researchers have studied the reasons for these changes and how being more settled affects people, not many studies have examined the patterns of settlement of people who are becoming more settled or how these patterns may be related to how people do economically once they become settled. This study is focused on settlement patterns in four Maasai villages in northern Tanzania. The study used geographic information systems and data collected by satellites to map the location of Maasai households, called bomas, in the four villages, and the environmental characteristic of where people do and do not live on the landscape. This study also looked at measures of income and economic activity for 111 households to see if the location of a household on the landscape effects people’s economic choices and outcomes. This study found that certain environmental factors in the area do influence where people live, particularly soils types and climate, but did not find that where people live has strong influence on how they do economically.

During recent years the high country of the South Island has attracted a good deal of attention from farm economists, soil conservationists, geographers and also politicians. With the present need for increased national production the problem of keeping the high country in productive occupation is the subject of justifiable concern. The purpose of this regional study is to describe one of the most distinctive areas in the high country, and to discuss the problems which have caused the recent Royal Commission on the Sheep-farming Industry in New Zealand to investigate the general economic position of the runholders. Besides being a well-defined physiographic unit, the Mackenzie Basin or, as it is better known to the local people, the Mackenzie Country has a distinctive character of its own. On entering Burkes Pass even the most casual observer cannot fail to notice how different the landscape within the basin appears compared with that outside. This large, gravel-filled intermontane depression with its vast expanse of dun coloured tussock and its clear, dry climate seems to have a special flavour which distinguishes it from any other part of either Canterbury or Otago. Probably the most striking feature of the basin is its monotonous uniformity of both physical conditions and human activities. The extensive sheep-farming economy has imposed a distinctive pattern of land use over the whole area. Not only does the landscape have a similar appearance everywhere but, because of their common int erests, the people all tend to live alike and think alike. Before 1939 the basin was solely a sheep-grazing area but, with the recent developments connected with the storage of water in the lakes for the generation of hydro-electricity, the Mackenzie Country has assumed a new importance. With the dam-building schemes at Tekapo and Pukaki an entirely new element has been introduced into the landscape - the large Public Works Camp. These camps, however, are, for the most part, temporary features and the sheep-station remains the typical unit of settlement. For this reason the major part of this study is devoted to a description of the landscape as it has developed under the extensive sheep-farming economy and a discussion of the problems resulting from the exploitation of the natural vegetation. When the early settlers first took up their runs they had the opportunity of making the Mackenzie basin one of the best merino grazing areas in New Zealand. In most cases that opportunity was lost, due partly to ignorance of proper grazing methods under sub-humid conditions and partly to short-sighted practices caused by temporary economic difficulties. Over-burning and over-stocking extracted an early toll from the vegetation cover which, in spite of numerous attempts can never be fully repaid. By deliberately introducing rabbits into the area the early runholders made their third and possibly their greatest mistake. These rabbits were allowed to multiply unchecked for nearly twenty years before it was realised what a menace they were likely to become. By that time it was too late. Today, the rabbit is generally considered to be the chief cause of the disturbing decline in the sheep carrying capacity of the Mackenzie Country. Altogether, unwise burning, overstocking and rabbits have caused such a deterioration in the tussock cover that Cumberland's description of some parts of the basin as "deserts in the making" is quite appropriate. Admittedly conditions are not as bad as in the "man-made deserts" of Central Otago but a serious problem at present confronts the Mackenzie runholders.

This study focuses on the constraints, adaptations and innovations in the livelihoods of Orma pastoralists. The fieldwork took place with families around Tiltila, Waldena and Kalalani over a period of 9 months in 2007/08. The position of pastoralist peoples in East Africa is characterised by social, political and economic marginalisation, weak land tenure, and declining per capita livestock holdings, while their shrinking grazing lands are widely regarded to be on the front line of climate change, both in terms of climate impacts and biofuel/agribusiness land pressure. The dearth of good quality data on pastoralist populations and livelihoods is widely cited as one of the fundamental barriers to improving the effectiveness of development support in the drylands. This study seeks to address these knowledge gaps for Orma pastoralists, while contributing to the body of theory on pastoralist livelihood dynamics. Data on the effects of wealth, education and food aid on household mobility were analysed using a theory of asset threshold dynamics. An adapted typology of livelihood strategies was developed to interpret and structure the data. Using child mortality as a proxy for respondent health, the impacts of wealth and mobility status on families’ health were explored. In the context of an almost total lack of data on community redistribution of food aid, both for the Orma and for East African pastoralists more generally, the study provides empirical data on de facto community food aid allocation patterns. The study also examines a controversial large-scale expropriation of land in Tana River (subsidised under the Kyoto Protocol’s Clean Development Mechanism) which will undermine the capacity of Orma pastoralists and other minority groups, to adapt to increased and more extreme environmental variability. In an environment in which enrolment in formal education is very low (particularly for girls), the study found that community nursery schools represent a relatively recent (and thus far undocumented) innovation organised and funded by groups of parents. The data demonstrates unprecedented levels of female enrolment despite cost constraints faced by least wealthy families. It is therefore suggested that incorporation of the community nursery model into the basic literacy element of the proposed national distance learning strategy, offers significant potential for addressing ‘Education For All’ in Kenya’s drylands.

The Tarangire ecosystem of northern Tanzania is proclaimed a site of global biodiversity significance. The economic value of wildlife in Tarangire and Lake Manyara National Parks is substantial and growing. Maintaining the health of these parks is important to Tanzania’s overall tourism industry and macroeconomic health. A considerable proportion of Tarangire’s wildlife leaves the park for approximately six months a year, migrating onto village lands under the jurisdiction of local communities. Of particular importance are grazing and calving areas in the Simanjiro Plains. Conservation of the ecosystem’s migratory wildlife populations largely depends on maintaining these habitats on communally owned lands. However, populations of most large mammal species have declined by over fifty percent in the last decade. The progressive conversion of pastoral rangelands to agriculture is believed to be a major contributing factor to this decline. Community-based conservation (CBC) interventions in the Tarangire ecosystem aim to increase the combined economic returns from wildlife and pastoral livestock production in order to reduce incentives for non-wildlife compatible agricultural land-use change. Increased State investment in CBC, continued growth in photographic and hunting tourism revenues, and large infusions of funding from international conservation organisations suggest that substantial potential exists for CBC to play a significant role in poverty reduction and biodiversity conservation. This thesis examines the fortunes of CBC in the Tarangire ecosystem. It uses a household survey conducted in a village earning substantial wildlife tourism revenues to show that wildlife benefits are concentrated in the hands of the elite, and have limited livelihood or conservation impacts. By documenting the root causes of local resistance to conservation, this thesis explains the failures of new conservation strategies in Tanzania.

This doctoral dissertation revisits the horse in Blackfoot culture in order to explore how its adoption altered Blackfoot hunting practices and landscape uses during the Contact Period in the Northwestern Plains of North America. The Blackfoot provide one of the best avenues for research into the horse's impact on big-game hunters because of their pre-contact trajectory, history of interaction with other groups, detailed ethnographic record, and continued investment in equestrianism. While the socio-economic consequences of the horse's introduction have been studied from a historical perspective, the archaeology of this transition remains ambiguous. This project presents a new, archaeological dimension to the dynamics of the Blackfoot equestrian transition by incorporating material culture with traditional knowledge, historic accounts, and geospatial data into a multi-scalar, transnational interpretation of the horse's impact on both Blackfoot social, economic, religious, and spiritual life, as well as the way in which Blackfoot peoples used and understood their landscape. The results of this study show how these changes may be best understood as a transition in modes of production from hunting and gathering to nomadic pastoralism. In this endeavor, this project contributes new theoretical and methodological approaches as well as substantive new data to our understanding of hunting and pastoralism among people of the Northwestern Plains.

The late Holocene marks a period of significant population movement and subsistence change throughout much of sub-Saharan Africa. Around 3500 BP it appears that foraging populations in southernmost South Africa began to experience stress related to an increasing population and changing climatic conditions. Approximately 1500 years later a new form of subsistence - sheep herding – emerged in areas previously occupied solely by foragers, but was not exclusively adopted. The mechanisms surrounding the introduction of this new subsistence strategy – an indigenous adoption via diffusion or a foreign migration - remain unresolved. This study takes a biological approach to this significant question in southern African prehistory by exploring a collection of Later Stone Age skeletal remains that predate and postdate the appearance of pastoralism in order to determine if any significant changes in skeletal morphology indicative of population discontinuity can be identified at 2000 BP. A collection of seventy-three Later Stone Age adult skeletons (31 M, 42 F) with newly generated radiocarbon dates ranging from 8000 BP to 300 BP (uncalibrated) from the Eastern Cape Province of South Africa forms the basis of this study. Questions surrounding population continuity or discontinuity associated with the advent of sheep herding are investigated by examining metric variables collected from the cranium, post cranial skeleton and dentition, in conjunction with cranial discrete traits. Some changes in skeletal morphology are observed, but the timing, pattern and magnitude of these changes are not consistent with a foreign migration. A reduction in overall skeletal size in the absence of changes in shape corresponds with the period of forager intensification. Body size rebounds at around 2000 BP when evidence for a new form subsistence, sheep herding, is first observed in this region, suggesting that some foragers may have adopted sheep and the herding way of life as a stress relieving mechanism, while others maintained the foraging lifestyle. The timing of the observed changes in skeletal size, the absence of shape changes and the homogeneity in cranial discrete trait frequencies through time argues against the idea that sheep herding was introduced to the Cape region by outsiders. Rather, the findings of the current study suggest sheep herding was an indigenous development among existing foragers.

(Agro)pastoralism in Sahelian Niger, as elsewhere, operates through household enterprises. Katsinen-ko’en (Fulбe) households, interconnected within kin and community networks, utilize a range of flexible strategies to manage a variety of ecological and economic risks. This dissertation argues that (agro)pastoralist households and communities maintain or improve viability in risky environments first by employing various mobility patterns, among other strategies, and relying on the tightly knit interdependence between household and herd. Secondly, households that most successfully sustain a cooperative integrity (i.e. partnerships between husband and wife, or wives, and parents and children) to negotiate decisions and strategies best withstand adversities such as droughts. The continuance of vital links between household and herd helps the household enterprise more easily weather difficult times and profit during advantageous times. Thirdly, the transfer of endowments from parents to children of ecological, economic and political knowledges and socio-economic networks ensures the continuity of family livelihoods. This dissertation analyzes a range of household/herd mobility patterns on a livelihood continuum from sedentary agropastoralism to exclusive pastoralism, and the household decisions that lead to those mobilities. In this way, it adds to a growing body of literature that examines household strategies employed in very uncertain natural environments, contributing to pastoral studies and environmental anthropology. By folding household economics and political ecology into household ecology, it analyses resource and asset transfers within and between households, all under the influence of the natural and political-economic environments. Contributing to development anthropology, I argue that the most important buffer against the risks of unpredictable environments is a stable, undivided household, migrating with and managing its own herd. I conclude by showing how development research and projects should support household/herd integrity to enhance livelihood security. When government or development agencies institute policies and projects that remove children from the household, or separate households and herds, they endanger the integrity of the household and the reproduction of livelihoods that make essential contributions to national economies. Rather than urging pastoralists to modify their livelihoods to fit images held by ABSTRACT OF DISSERTATION administrators, these organizations and agencies should help pastoralists to build on adaptations that already facilitate their management of risky environments.
