Arctic ecosystems are undergoing rapid environmental transformations. Climate change is affecting permafrost temperature, vegetation structure, and wildlife populations, and increasing human development is impacting a range of ecological processes. Arctic indigenous communities are particularly vulnerable to environmental change, as subsistence harvesting plays a major role in local lifestyles. In the Inuvialuit Settlement Region (ISR), in the western Canadian Arctic, indigenous land-users are witnessing a broad spectrum of environmental changes, which threaten subsistence practices. Local cumulative effects monitoring programs acknowledge the importance of subsistence land use; however there are few cumulative effects assessments that measure the impact of environmental change on land-based activities. My MSc addresses this gap with a broad-scale spatial inventory that measures the distribution of multiple disturbances in the mainland ISR, and assesses their overlap with community planning areas, land management zones, and caribou harvesting areas. I also generated nine future disturbance scenarios that simulate increases in both human development and wildfire occurrence, in order to understand how additional environmental change may affect the availability of un-impacted harvesting lands. I used the conservation planning software, Marxan, to assess the impact of increasing environmental perturbations on the availability and contiguity of 40 subsistence harvesting areas. Results show that the study region is already impacted by multiple environmental disturbances, and that these disturbances overlap considerably with wildlife harvesting areas. This limits the success of Marxan runs that attempt to conserve high percentages of subsistence use areas. It becomes increasingly difficult to conserve large, contiguous assortments of wildlife harvesting areas when using Marxan to assess conservation potential in future disturbance scenarios. In a separate study, I conducted 20 semi-structured interviews in the communities of Inuvik, Aklavik, and Tuktoyaktuk that explored the impact of environmental change on Inuvialuit land-users. Participants in my study indicated that wildlife harvesting in the region is being affected by a range of environmental disturbances and that this change is typically considered to be negative. Climate change-related disturbances were noted to affect travel routes, access to harvesting areas, wildlife dynamics, and the quality of meat and pelts. Human activity, such as oil exploration, was noted to impact both wildlife populations and harvesters’ ability to use the land. These observations are an important contribution to local cumulative effects monitoring because they highlight local accounts of environmental change, which are often missed in broad-scale assessments, and they emphasize the concerns of local land-users. This underscores the importance of including indigenous insights in cumulative effects monitoring and suggests that combining quantitative assessments of environmental change with the knowledge of local land-users can improve regional cumulative effects monitoring. / Graduate

Thesis (PhD (Botany and Zoology))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Although the impacts of biological invasions are widely appreciated, a bias exists in research effort to post‐dispersal processes because of the difficulties of measuring propagule pressure and the detecting of newly established species. Here the Antarctic is used as a model system in which to quantify the initial dispersal of alien species and investigate the factors that contribute to the establishment and range dynamics of alien species once they have arrived in the region. Human movements are known to transport alien species into the Antarctic, some of which have successfully established and had wide ranging consequences in recipient ecosystems. Considering terrestrial flora, this research found that over 700 seeds from 99 taxa, including some species known to be invasive, are transported into the Antarctic each year in association with South African National Antarctic Programme (SANAP) passenger luggage and cargo. The first ever assessment of propagule drop‐off indicated that 30‐50% of these propagules will enter the recipient environment. Further results suggested that the construction of the British Antarctic Survey Halley VI station will facilitate the transport of over 5000 seeds from 34 taxa into the region, making this a significant pathway for introductions. Propagule pressure due to SANAP logistics is also considerable for marine species. Fouling assemblages on the external hull surfaces of the SANAP resupply vessel, the SA Agulhas, form only once the vessel’s anti‐fouling paint has been damaged by travel through sea ice and are characterised by low diversity. Ice scour prevents fouling assemblages from being transported to the Antarctic continent, but assemblages remain largely intact when travelling to sub‐Antarctic Islands. In the sea‐chests of the vessel populations of a known invasive, Mytilus galloprovincialis, were found with some individuals having survived transportation to the Antarctic region on multiple occasions. Once species have overcome initial dispersal barriers, they face further ecological and physiological challenges in order to establish in the recipient region. The parasitoid wasp Aphidius matricariae was first recorded on Marion Island in 2001. Surveys around the island show that adult abundance and the frequency of aphid parasitism are highest adjacent to a common anchor point of the SA Agulhas and decline away from this region. Genetic diversity was low, suggesting that the population was established from a single introduction. This highlights that high propagule pressure is not necessary for successful establishment of introduced invertebrates. Another species that has overcome the dispersal barrier is the terrestrial slug Deroceras panormitanum, which was introduced to Marion Island in the 1970’s and has since spread throughout much of the coastal habitat of the island. For this species range limits are set by intolerance of low temperature and salinity, and abundance structure is characterized by patches and gaps which are associated with this species inability to tolerate dry conditions. To prevent further alien introductions in the region, targeted management of high risk pathways is required. In addition, increased vigilance is needed to detect and manage newly established aliens before their ranges expand. / AFRIKAANSE OPSOMMING: Alhoewel die impak van biologiese indringings in die breë waardeer word, bestaan daar vooroordeel in navorsingspogings ten opsigte van na‐verspreidingsprosesse, weens die moeilikhede om verspreidingseenheid druk te meet en in die opsporing van nuut gevestigde spesies. Hier word die Antarktiese streek as ‘n model sisteem gebruik waarin die aanvanklike verspreiding van uitheemse spesies gekwantifiseer kan word en om die faktore wat bydrae tot die vestiging en grens dinamika van uitheemse spesies te ondersoek, wanneer hulle in ’n streek aangekom het. Menslike bewegings is bekend daarvoor om uitheemse spesies na die Antarktiek te vervoer, sommige waarvan suksesvol gevestig het en omvattende gevolge in die ontvanger ekosisteme gehad het. Aangaande terrestriële flora het hierdie navorsing gevind dat oor die 700 sade van 99 taxa, insluitende sommige spesies wat bekend is om indringend te wees, jaarliks na die Antarktiek vervoer word in assosiasie met die Suid Afrikaanse Nasionale Antarktiese Program (SANAP) se bagasie en vrag. Die eerste waardebepaling van verspreidingseenheid afgooi het aangedui dat 30‐50% van hierdie verspreidingseenhede die ontvanger omgewing sal binnedring. Verdere resultate het voorgestel dat die konstruksie van die Britse Antarktiese Opname Halley VI stasie die vervoer van 5000 sade van 34 taxa sal fasiliteer die streek in, wat dit ’n betekenisvolle weg maak vir indringings. Verspreidingseenheid druk is ook, as gevolg van die SANAP logistiek, aanmerklik vir mariene spesies. Vuilgoed versamelings op die eksterne omhullende oppervlaktes van die SANAP her‐voorsieningsvaartuig, die SA Agulhas, vorm wanneer die vaartuig se anti‐vuilgoed verf beskadig is met reis deur see‐ys en word gekenmerk deur lae diversiteit. Ys skuring voorkom dat vuilgoed versamelings vervoer word na die Antarktiese kontinent, maar versamelings bly grootliks vasgeheg wanneer na sub‐Antarktiese eilande gereis word. Populasies van ’n welbekende indringer, Mytilus galloprovincialis, is gevind in die see‐storingsarea van die vaartuig, met sommige individue wat die vervoering na die Antarktiese streek oorleef het op verskeie geleenthede. Wanneer spesies die aanvanklike verspreidingshindernisse oorkom het, staar hulle verdere ekologies en fisiologiese uitdagings in die gesig ten einde in die ontvanger streek te vestig. Die parasitiese wespe Aphidius matricariae is vir die eerste keer op Marion aangeteken in 2001. Opnames om die eiland toon dat volwasse oorvloed en die frekwensie van plantluis parasitisme die hoogste is aangrensend die algemene ankerpunt van die SA Agulhas en afneem weg van die omgewing af. Genetiese diversiteit was laag, wat voorstel dat die populasie gevestig het van ’n enkele bekendstelling. Dit lig uit dat hoë verspreidingseenheid druk nie nodig is vir die suksesvolle vestiging van bekendgestelde invertebrata nie. ‘n Ander spesie wat die verspreidingshindernisse oorkom het is die landslak Deroceras panormitanum wat in die 1970’s op Marion Eiland bekendgestel is en wat sedertdien versprei het oor meeste van die kushabitat van die eiland. Vir hierdie spesie word grens limiete vasgestel deur onverdraagsaamheid vir lae temperature en saliniteit en die oorvloedstruktuur word gekenmerk deur laslappe en gapings wat geassosieer word met die spesie se onvermoë om droë kondisies te hanteer. Om verdere uitheemse bekendstellings in die streek te voorkom, word geteikende bestuur van hoë risiko weë vereis. Toenemende waaksamheid is bykomend nodig vir die opsporing en bestuur van nuutgevestigde uitheemse spesies voordat hulle grense verbreed.

The adoption of the neo-liberal model in the mid-1980s has forced the governing elites to reconfigure the Mexican State. However, the consolidation of a neoliberal State continues to be incomplete and it has been problematic to fully integrated the Mexican economy in the global market due to the increasing organized crime, the dismantling of previous post-revolutionary control mechanisms, and the growing mobilisation of organised indigenous opposition ranging from the peaceful obstruction of hydroelectric mega-projects in their territories to armed struggle. In view of the State crisis, this thesis argues that there has been a shift in the system of control mechanisms of the State that is leaning towards a more recurrent use of open violence to implement its neo-liberal State project. From a theoretical perspective, the research proposes an innovative approach to understanding the formation of the post-revolutionary State, which transcends the State violence dichotomy established between the ´corporatist´ and the ´critical´ approaches in the contemporary literature. The research highlights the wide spectrum of control mechanisms from hegemonic domination to violence used by the governing elites to compensate the unfinished State formation process in order to maintain socio-political stability without profound structural changes. It explores the enhanced tendency of State violence to replace incorporation in Statesociety relations since the efforts to restructure the economy from the 1980s onwards. The thesis analyses how this tendency has grown particularly in response to indigenous movements in the South of Mexico. The argument is substantiated empirically with two case studies undertaken in the sub-region of Costa Chica-Montaña of Guerrero with data from 79 semi-structured interviews with a wide range of social and political actors, and participant observation in ten indigenous communities. The case studies explore the different State control mechanisms used to advance the State formation model in the post revolutionary period; the impact of the crisis of those mechanisms in the sub-region; the violent resistance of local bosses to the loss of power, and the multiples indigenous responses to the implementation of neoliberal policies in their territories. This research also includes a comparative study to explain some factors that strengthen indigenous articulations, as well as their limits in an era of neoliberal globalisation. One of the most important research findings is that neoliberalism has further weakened the 'civilianisation' power of the State to deal peacefully with civil society sectors, particularly with indigenous peoples, while it has strengthened its 'centralised-coercive' power to carry out the imposed State model. Another finding is that the indigenous initiatives that have reinvented themselves through a new version of their practices and broader alliances have consolidated their alternative models. In contrast, the indigenous responses that have reproduced their traditions have failed.

Recently, the issue of poverty amongst indigenous people has become a significant topic in literature on social policy and development studies. The literature mainly looks at this issue in terms of an unequal and one-sided relationship between the mainstream society and an indigenous minority group. This thesis seeks insights into the more diversified circumstances and experiences of poverty amongst indigenous people. The following questions are addressed: (1) Why and how is the poverty of indigenous people reproduced over time and space? (2) How can we understand patterns of differentiation between indigenous people? (3) What is the balance between structural opportunity and constraint in the lives of indigenous people? (4) To what extent do people exercise agency to cope with or overcome their poverty situations? The thesis adopts an ethnographic approach, including participant observation and interviews in four villages of Taiwanese indigenous people. It explores the connections between poverty dynamics and diversified patterns of socio-economic action amongst indigenous people. Hogget and Greener's model of agency, which contains the essential theoretical views of Giddens (the ability of agents to act) and Bourdieu (the embedded corporeal disposition of human agents) are used to make sense of this exploration. The thesis finds that the actions of indigenous people as human agents are differentiated. Actions are not only motivated by strategic plans and emotions but are also influenced by the agents' socio-economic positions, such as their occupations and education and those of their parents. The differentiated socio-economic activities of agents, in turn, have a strong effect on the stratification of their living standards.

This dissertation is a comprehensive description of the grammar of Sierra Popoluca (SP, aka Soteapanec), a Mixe-Zoquean language spoken by approximately 28,000 people in Veracruz, Mexico. This grammar begins with an introduction to the language, its language family, a typological overview of the language, a brief history of my fieldwork, and the methodology undertaken in this study. The grammar continues with a description of the phonology of SP, followed by an overview of the word classes, including verbs, nouns, relational nouns/postpositions, adjectives, adverbs, and numbers, and formative types. The bulk of this grammar is devoted to the morphosyntax of Sierra Popoluca, including nouns and nominal morphology, verbs and verbal morphology, and the mechanisms for expressing tense, aspect, mood, and modality. The grammar also describes the complex predicate formation strategies and sentence-level syntax. A compilation of interlinearized texts appears in the appendix. Sierra Popoluca is an agglutinating, polysynthetic, head-marking language with a complex verbal system. It has ergative-absolutive alignment and its grammar is sensitive to animacy and saliency hierarchies, evident in the case marking and `split' plural systems. Its constituent order is verb-initial, although word order is pragmatically determined. Sierra Popoluca has a number of strategies to form complex predicates, which include verb serialization, noun incorporation, and dependent verb constructions. The data available in this grammar contributes a body of data and descriptive analysis to broad theoretical areas of linguistics as well as existing research on the Mixe-Zoquean language family, languages throughout Mesoamerica, and especially the Gulf branch of the Zoquean family. / text

This dissertation is an ethnographic study of race and other forms of social categorization as approached through the discourse of the indigenous Chachi people of northwestern lowland Ecuador and their Afro-descendant neighbors. It combines the ethnographic methods of social anthropology with the methods of descriptive linguistics, letting social questions about racial formation guide linguistic inquiry. It provides new information about the largely unstudied indigenous South American language Cha’palaa, and connects that information about linguistic form to problems of the study of race and ethnicity in Latin America. Individual descriptive chapters address how the Cha’palaa number system is based on collectivity rather than plurality according to an animacy hierarchy that codes only human and human-like social collectivities, how a nominal set of ethnonyms linked to Chachi oral history become the recipients of collective marking as human collectivities, how those collectivities are co-referentially linked to speech participants through the deployment of the pronominal system, and how the multi-modal resource of gesture adds to these rich resources supplied by the spoken language for the expression of social realities like race. The final chapters address Chachi and Afro-descendant discourses in dialogue with each other and examine naturally occurring speech data to show how the linguistic forms described in previous chapters are used in social interaction. The central argument advances a position that takes the socially constructed status of race seriously and considers that for such constructions to exist as more abstract macro-categories they must be constituted by instances of social interaction, where elements of the social order are observable at the micro-level. In this way localized articulations of social categories become vehicles for the broader circulation of discourses structured by a history of racialized social inequality, revealing the extreme depth of racialization in human social conditioning. This dissertation represents a contribution to the field of linguistic anthropology as well as to descriptive linguistics of South American languages and to critical approaches to race and ethnicity in Latin America. / text

This dissertation is an analysis of aspects of the phonology and morphology of Zenzontepec Chatino (ISO 639-3: czn), a Zapotecan (Otomanguean) language spoken in a remote area of Oaxaca, Mexico (16°32"N, 97°30"W). There are an estimated 8,000 speakers of the language, but its vitality is weakening due to accelerating shift to Spanish. The phonological analysis begins with the segmental inventory. After that, the autosegmental contrasts are treated, with the highlight being the tone system. The tone bearing unit is the mora, which may bear high tone /H/, mid tone /M/, or no tone Ø. In tone systems with a three-way contrast, the unspecified category is usually the mid-level one. Therefore, Zenzontepec Chatino is typologically unusual in this respect. Special chapters are devoted to phonotactics and phonological processes, including a play language of "speaking backwards" that sheds light on crucial phonological questions, such as the status of glottalization and the limits of prosodic domains. There are also chapters on special topics in phonology: regional variation, Spanish loanwords, and sound symbolism. Another chapter bridges the phonology and the morphology, defining and comparing the phonological word versus the grammatical word, and outlining the basic morphological building blocks: roots, affixes, clitics, and particles. After that, lexeme classes are defined using morphosyntactic criteria, providing a syntactic sketch of the language. The language is strongly head-marking with somewhat agglutinating and synthetic morphology. Another chapter gives an overview of verbal morphology, which is the locus of most of the language's morphology. The dissertation is the beginning of a full descriptive grammar and is part of a larger project to document Zenzontepec Chatino, complementing a dictionary and a documentary text corpus recorded in the community with native speakers. The theoretical approach is one in which the language is explored as much as possible on its own terms using naturalistic textual data supplemented by lexicographic and elicited material. The analysis is not bound by any formal framework, but it is informed by socio-cultural and diachronic considerations. It is situated in a typological perspective to offer more of a contribution to the scientific understanding of the structure of human language. / text

Faced with the profound social and ecological threats posed by extractivist projects such as large hydroelectric dams, wind farms, and mining operations, many indigenous communities and their allies in Mexico have articulated new forms of contentious politics into a broad territorial defense movement. This project explores the strategies of contention practiced by an anti-mining movement based in the Municipality of San José del Progreso in the southern state of Oaxaca. As a deeply-divided community that has suffered increased violence and conflict directly related to a Canadian-owned gold and silver mine operating in its vicinity, it presents a valuable case study in how strong social movements can still develop under conditions of disunity. This study combines ethnographic and archival research methods to uncover the deep historical roots of community division, and to develop a close analysis of the contentious strategies employed by the anti-mining movement. The historical record and local narratives show the central role that hacienda colonialism played in creating a salient geography of ethnic discrimination and division in the municipality whose effects can still be seen today. In response to the ongoing processes of colonization and dispossession in San José del Progreso, a legacy of contention has defined and defended both campesino (peasant farmer) and indigenous claims to local territory. More than a series of instrumental strategies designed to expel the hacienda and later mine project, this politics of contention operates as a form of social memory to produce a hybrid form of indigenous/campesino identity linked to healthy land stewardship, an interconnectedness between the earth and human subjects, and a shared history of struggle. As a result, the anti-mining movement in San José del Progreso has shown success in converting its troubled past and checkered present into the foundations of a healthy social and ecological commons, independent of its failure to fully-unite the municipality or close down the mine project in the short-run. / text

Postcolonial critiques have emphasized the need for Western psychology to become more reflective of the histories, worldviews, and lived realities of historically marginalized communities across the globe (Comas-Díaz, 2000; Duran & Duran, 1995; Pickren, 2009). These works have included the contributions of liberation psychologists who advocate for the need to privilege the knowledge systems, concerns, and perspectives of local communities when proposing avenues for psychological research, intervention, and theoretical development (Watkins & Shulman, 2008). Recognizing the legacies of colonialism in North America, U.S. psychologists working with Indigenous communities have advocated for better collaboration with grassroots elders, teachers, and community groups, noting the importance of recognizing the validity of Indigenous epistemologies and the colonizing tensions that still exist between Indigenous healing systems and Western psychology (Duran, Firehammer & Gonzalez, 2008; Gone, 2007; Gone & Alcántara, 2007). Against this backdrop, the present research was carried out as an immersive, long-term ethnographic study in collaboration with Alma de Mujer (Alma), a community of Indigenous-identified women in central Texas, who are committed to creating accessible spaces for their communities to practice Indigenous lifeways and healing. Employing reciprocal ethnographic methods, the author spent two years participating in events and gatherings with the Alma community, as well as conducting in-depth interviews. Community members were consulted on an ongoing basis about the development of the research. The document centers on four objectives: First, the author traces the history of the Alma community as it emerged from social liberation and psychospiritual healing movements over the latter half of the 20th century. Second, based on the women's stories, the author presents community members' narratives about how healing is situated within the community's Indigenous knowledge systems. Specific attention is given to the holistic and reciprocal nature of healing in these stories. Third, the author includes contributions from Indigenous healers who remark on their experiences of the tensions between Indigenous healing systems and Western mental health institutions. Fourth, the author concludes with a personal critical reflection as a trainee in Western psychology and considers how dialogues between local Indigenous communities and Western psychology might be further explored. / text

Bolivia and Guatemala experienced a process of education reform in late 90's. Even though both countries had great international support to eliminate inequalities, especially among indigenous peoples, the domestic political contexts determined to what extent such changes were possible to make. In Bolivia the process started in 1994 with the signing of the Reform Law of Education, and in Guatemala in 1996 with the signing of the Peace Agreements. After more than two decades Bolivia and Guatemala present very different outcomes derived from their respective education reforms. This study is a comparison of them, an attempt to unveil the reasons why Bolivia has moved forward in terms of diversity, indigenous languages, and inclusion while Guatemala has apparently nullified the education reform process and remains in authoritarianism. / text
