The indigenous peoples of the Northwest Coast of North America are widely believed to have been true “hunter‐fisher‐gatherers,” lacking plant cultivation of any kind. This depiction of the region's indigenous inhabitants emerged within early colonial accounts and was perpetuated within the literatures of geography, anthropology, and archaeology. Still, there is ample evidence of plant cultivation available from archival, archaeological, and ethnographic sources. In particular, the peoples of coastal British Columbia created large gardens of edible estuarine plants, using sophisticated indigenous technologies. The oversight of these practices in written representations of the region reveals consistent patterns of bias, emanating from the agendas of colonial agents and early academics alike. In turn, this bias has undermined aboriginal traditions of cultivation and indigenous land claims.  相似文献

Chagusaba, which is traditional tea-grass integrated system in Shizuoka, is one of Globally Important Agricultural Heritage Systems (GIAHS) sites in Japan. Chagusaba provide an important habitat for natural plant species. In this study, we investigated the flora in Chagusaba and environmental factors to affect the number of native species estimated their diversity. Fifty Chagusaba were classified in to five vegetation types by Two-way indicator species analysis. In addition, high number of native plant species Chagusaba had low soil pH, covered large areas, and were in places where the land had not been modified. Through statistical analysis (GLM), we found that land modification had an especially significant effect on the diversity of native plants, and that the diversity of native plants was reflected in the history of the use of the land.  相似文献

The Mapuche people have a deeply rooted tradition of wild plant use for their subsistence. In this study we evaluated whether plant selection by the Mapuche is influenced by environmental constraints. Selection patterns of wild plant richness were compared in two Mapuche communities sharing the same traditions and beliefs but inhabiting different environments. Similarities and differences in the use patterns of wild medicinal and edible plants were quantitatively analyzed by using concepts derived from ecological theory. The Cayulef community is settled in the NW Patagonian (herbaceous) steppe while the Curruhuinca community is established near the Andean temperate forest, 100 km away from each other. Free-listing and semi-structured interviews were conducted with 32 families in Cayulef and 39 in Curruhuinca corresponding to 80% and 40% of each population, respectively. Data were analyzed by means of the Jaccard similarity index and statistical tests. The main results of this study showed that the home environment is a determinant factor that influences which plant species are utilized, as is the anthropic environment (with its high exotic species richness) in each community. However, similar patterns were found with respect to plant families, ways of utilization, plant parts and life forms utilized irrespective of where the communities are settled. In addition, in both populations, wild plant richness was significantly higher for medicinal than for edible species. Our results showed that the use of wild plants is primarily based on the utilization of species belonging to the nearest ecological environments that have both therapeutic and dietary functions.  相似文献

毛乌素沙地3种飞播植物种群分布格局的研究   总被引:4,自引:0,他引:4  
沈渭寿 《中国沙漠》1998,18(4):372-378
在播区水平和群落水平上,讨论了毛乌素沙地3种沙丘类型区飞播后,沙地由流动到半固定和固定状态的变化过程中,籽蒿、羊柴和花棒3个主要飞播植物种群分布格局的变化,以及各种状态下决定种群分布格局的主导因素。研究表明:在沙地处于流动状态下,不论是播区水平还是群落水平上,幼苗的分布格局都是由环境的空间异质性决定的;在半固定状态下,种群的分布格局是植物自身的生物生态学特性和环境因素共同作用的结果;而在固定状态下,种群的分布格局几乎全部是由植物自身的生物生态学特性所决定的。  相似文献

This article discusses the relevance of the work of Pierre Gourou for Vietnamese and non‐Vietnamese scholarship on colonial and postcolonial rural society in Vietnam. The term “tropicality” is used to situate Gourou's work within the framework of both French and Vietnamese regimes of truth. It is argued that Gourou was aware of the complex human geographies of the tropics and monsoon Asia and the challenges this posed to both Western and “tropical” peoples. Gourou and the issue of tropicality is used to show that Vietnamese scholars did not completely reject French colonial systems of knowledge, and that decolonisation did not herald a complete shift in knowledge about rural Vietnam. Rather, since the 1940s there has been antagonism and accommodation between colonial and postcolonial, French and Vietnamese modes of knowledge production. While Gourou underscored the otherness of the tropics, and there are colonial overtones in his work, he had an immense influence on indigenous ethnography and geography in Vietnam and elsewhere in the formerly colonised world. The article traces this important influence and how it has been both questioned and affirmed since independence in the Vietnamese context. It is suggested that the humanistic approach that Gourou pioneered in his 1936 study of the Red River Delta of northern Vietnam has outlived and been able to overcome the setbacks and drawbacks of both colonial and revolutionary/Vietnamese politico‐intellectual projects.  相似文献

Severe erosion, initiated by climatic changes during the Late Pleistocene-Early Holocene period and resultant declines in dust deposition, causes the formation of waterfalls during the winter floods in many wadi systems in the central Negev desert of Israel. In some areas, erosion of the original loess substrate has been complete, so that the underlying rock has been exposed. We examined the effects of this erosion in four wadis in the central Negev desert on soil nutrients, plant community structure and plant quality. We predicted that erosion has caused reductions in soil nutrients. Reductions in soil nutrients should result in reductions in plant cover. Furthermore, reduced soil nutrient availability should cause reductions in the nutrient status and quality of the plants growing there. In addition to the loss of biodiversity that may result, this erosion may result in economic hardship for the Bedouin peoples whose herds depend on these resources. In this study, there were significant negative effects of erosion on soil organic carbon, nitrate nitrogen and water-holding capacity, but not on soil phosphorus, conductivity or pH. Furthermore, there was a negative effect of soil erosion on an overall measure of soil quality derived from a principal components analysis in three of the four wadis we studied. Erosion resulted in an increase in plant species richness and significantly altered plant community structure in eroded areas of wadis. Increased plant species richness in eroded sites is consistent with the intermediate disturbance hypothesis of plant community structure. Plants growing in eroded areas did not differ in two quality indices (nitrogen content and digestibility), although plants typical of eroded areas had significantly lower levels of common digestion inhibitors (total polyphenols) and toxins (alkaloids) than plants from undisturbed sites. These last-mentioned results are contrary to our prediction and are consistent with the notion that plants growing in disturbed (e.g. eroded) sites maximize growth at the expense of investments in defense.  相似文献

《Urban geography》2013,34(8):815-837
A comparison of the British and Dutch experience in the 20th century makes it possible to deepen our understanding of colonial urban housing policy, and hence of the colonial city in general. Both colonial powers expressed new concern about urban living conditions at the time when they began to promote colonial development. In the British case this began in the 1930s, largely in response to local unrest and partly because of international pressure. By the 1950s, British colonial governments used housing programs to placate nationalists and to help prepare colonial societies for self-rule. The Dutch undertook similar initiatives earlier, after 1901, by forming municipal governments, improving services in autonomous native settlements, and by bringing these kampongs under municipal control. Their initiatives were more a response to domestic considerations than to colonial unrest. The Dutch incurred expenditures beyond what Indonesians could afford, but were less active than the British in house-building. Their efforts flagged as nationalist sentiment grew. Neither colonial power responded directly to poor urban conditions. Although the colonial city might have existed, it did not shape colonial urban policy in a predictable way.  相似文献

This paper considers some of the ways in which travellers, administrators and academics in the colonial period sought to categorise the indigenous groups of Borneo. It focuses on Sarawak and North Borneo between about 1850 and 1920, and examines the use of stereotypical images of exoticism, fear and loathing in constructing different categories of peoples in the region. The paper argues that such categorisations were important in structuring the relationships between ruler and ruled, and in the development of particular regional and local identities.  相似文献

ABSTRACT

Urban greening is a buzz term in urban policy and research settings in Australia and elsewhere. In a context of settler colonial urbanism, like Australia, a first fact becomes clear: urban greening is always being practiced on unceded Indigenous lands. Recognising this requires some honest reckoning with how this latest urban policy response perpetuates dispossessory settler-colonial structures. In this paper, we listen to the place-based ontologies of the peoples and lands from where we write to inform understanding the city as an always already Indigenous place – a sovereign Aboriginal City. In so doing, the paper tries to practice a way of creating more truthful and response-able urban knowledge practices. We analyse three distinct areas of scholarly research that are present in the contemporary literature: urban greening and green infrastructure; urban political ecology; and more-than-human cities. When placed in relationship of learning with the sovereign Aboriginal City, our analysis finds that these scholarly domains of urban greening work to re-organise colonial power relations. The paper considers what work the practice and scholarship of ‘urban greening’ might need to do in order to become response-able and learn to learn with Indigenous sovereignties and ontologies.  相似文献

We studied the effect of ant herbivory on the establishment and survival of the annual plant Schismus barbatus. We hypothesized that ants may control this species when biomass of native plants is generally low during their vegetative period. We predicted that ant herbivory will decrease plant survival and reproduction. We tested our prediction with an insect exclosure experiment in a sandy desert of Northern-Central Monte.We found more than 12 000 established seedlings per square meter on early May, after two consecutive rain pulses of ca. 20 mm each. Overall, we found that almost 75% of recruited plants survived by the end of the cool season (September), and that 22–24% of the initially established plants survived as mature reproductive plants by the end of the growing season (December). Contrary to our expectation, insect herbivory did not affect plant establishment, plant survival or the proportion of flowering and fruiting individuals of S. barbatus.The large number of seedlings reported, the ability to exploit a temporal window free of plant competitors and enemies, and the availability of microsites where this species can succeed, all suggest that S. barbatus may have the potential to become an important plant invader in the Monte Desert.  相似文献

Medicinal plants and fungi play important roles in the health of Maliseet people of northern Maine, USA. A critical aspect of exercising choice in health care for this community is the ability to locate and have access to these plants. Habitat suitability modeling is a form of geospatial technology that can enhance health sovereignty by identifying locations in which populations of medicinal plants can be conserved or established. However, use of this technology within indigenous communities has been limited. Focusing on the medicinal plant muskrat root, Acorus americanus (Raf.) Raf., we generate a habitat suitability model for eastern Aroostook County, Maine (1,055,653.659 ha) that also takes community needs into consideration. Drawing on participatory ethnographic data as well as environmental characteristics, our model combines ecological and sociocultural parameters to identify previously unknown populations of A. americanus that are accessible to tribal elders. Our model successfully predicted 95% of A. americanus locations in our field validation data set of ∼71,000 ha. Results suggest that approximately 0.6% of our study area contains suitable habitat to plant muskrat root that could also meet tribal members' gathering needs for the future. Increasing the number of potential collection sites gives communities options for gathering, thereby enhancing health sovereignty. Broadly, our work suggests that, when done in partnership with communities, different forms of geospatial technology can be beneficial tools for efforts to promote health sovereignty.  相似文献

Editors' Note: The following is the ninth in the Singapore Journal of Tropical Geography Lecture Series. It is based on the plenary presentation of 3 September at the Annual Conference of the Royal Geography Society (with the Institute of British Geographers) held in London in 2010. In the search for a more international approach to theorizing cities, comparative methods hold considerable promise, although one concern might be that in their theoretical ambitions they foster a universalising approach rather than one appreciative of diverse and sometimes divergent urban experiences. The potentially universalizing ambitions of comparative methods lead some postcolonial theorists to question the extent to which comparativism carries the marks of colonial histories. Critics argue that some aspects of formal comparative methods can be traced to ambitious and geographically encompassing intellectual projects from the colonial era, when the interest and capacity to bring different parts of the world together within the same intellectual frame advanced significantly. This paper explores the complexities of these colonial lineages of comparative research with a view to assessing their implications for postcolonial comparative urbanism. It concludes by assessing the potential for more modest comparative experiments in a postcolonial vein through attending to the diverse vernacular cosmopolitanisms of cities. Following the spatialities of cities themselves has the potential to offer non‐universalizing but variously internationalizing theoretical engagements with different places.  相似文献

Alpine medicinal plant trade and Himalayan mountain livelihood strategies   总被引:5,自引:0,他引:5  
Commercial alpine medicinal plants are collected from the wild by local rural households throughout the Himalaya and sold in order to increase household incomes. Recent studies indicate that this annual trade amounts to thousands of tonnes of roots, rhizomes, tubers, leaves, etc., worth millions of US dollars. The main market is in India. Based on a national survey, including the most commonly traded species, and a village study this paper investigates the importance of the alpine medicinal plant trade at national and local levels in Nepal. The national survey included standardized open-ended interviews with 232 harvesters, 64 local traders, 66 central wholesalers, 47 regional wholesalers, and 16 production companies. The village survey is based on the daily records of household activities in 15 households in a one-year period. The annual Nepalese alpine and sub-alpine medicinal plant trade is conservatively estimated to vary from 480 to 2500 t with a total harvester value of US$0.8–3.3 million; the average harvester value is estimated at US$66.0 ± 99.0. The trade in 1997/98 amounted to 1600 t with a harvester value of US$2.3 million and an export value equivalent to 2.5% of total export from Nepal. Medicinal plant harvesting was found to constitute an integrated part of local livelihood strategies, contributing from 3 to 44% (average of 12%) of the annual household income. Importance at household level depended on land and animal holdings, and the availability of adult male labour. The validity and reliability of methods and analyses is evaluated, and issues of conservation and management of alpine medicinal plant species under the community forestry scheme are discussed.  相似文献
