Determinants of Wild Fish Consumption in Indigenous Communities in the Ecuadorian Amazon

This paper analyzes the socioeconomic determinants of consumption of wild fish among the Kichwa and Shuar indigenous peoples in the Ecuadorian Amazon. The results of a random-effect linear model show that the consumption of wild fish is higher for households with younger heads that do not have off-farm work and reside far from urban centers, in communities with low population densities. Although various actors promoting aquaculture in the region often claim that it helps to relieve the pressure on wild fish stocks, no statistically significant effect of the consumption of cultivated fish on the consumption of wild fish could be shown. Thus, our analysis suggests that public policies and development interventions which increase access to off-farm employment can both improve local livelihoods and conserve biodiversity, but that the same affirmation cannot be made for the promotion of aquaculture.     

Who Is “Forest‐Dependent”? Capturing Local Variation in Forest‐Product Sale,Eastern Honduras

How researchers describe groups living within or near the world's tropical rain forests has important implications for how and why these groups are targeted for assistance by conservation and development organizations. This article explores how data about market behavior can be used to assess one aspect of forest peoples’ livelihoods: their “dependence” on forest resources as a source of market income. With the intent of revealing the importance of methodology to how we describe forest peoples’ livelihoods, I draw from a multiyear survey of market activity among the Tawahka Sumu of Honduras and distinguish nested measures of the Tawahkas’ engagement in forest‐product sale. Results indicate that whether or not the Tawahka —or any forest group — can be considered financially “dependent” on forest resources depends on the spatial and temporal scales at which data are aggregated. As a group, the Tawahka earned 18 percent of total market income from forest‐product sale, but their group profile masked a high degree of heterogeneity at the village and household level. Similarly, multiyear data indicated that while group‐level generalizations adhere from year to year, they belie considerable change in households’ market behavior across years. I discuss three ways in which the findings are relevant to the theory and practice of conservation and development in the humid tropics. I emphasize the importance of spatial scale in interventions, how market‐oriented conservation schemes can benefit from a broader conceptualization of the economic context in which forest‐product sale occurs, and how longitudinal analysis can reveal the dynamism of forest peoples’ livelihoods.

The household economy of pastoralists and wage-labourers in the Richtersveld, South Africa

The Richtersveld is situated in an arid environment and its inhabitants are confronted with various hazards. Based on data collected during 22 months of ethnographic fieldwork, the livelihood strategies of Richtersvelders are explored. Besides a thorough examination of the diversified economy, the internal institutional arrangements for pooling and redistributing resources within households are analysed in this paper. Encouraging household members to engage in different activities and to share their income—as well as skills to manage the household budget properly—are integral to diversification and reducing the vulnerability of households. This study has shown that even in a community marked by considerable dependence on wage labour, almost three-quarters of the households are directly involved in stock farming. Although pastoralism still plays an important role for households, it has shifted from being the core economic activity to being an insurance against unemployment and contributing to subsistence. Stock farming serves to build up resilience through the diversification of economic activities inside the household. In the South African context, the relevance of activities dependent on land has implications not only for rural development, but also for post-apartheid land and agrarian reform.     

农户土地规模与生产率的关系及其解释的印证——以吉林省为例

依据原中共中央政策研究室和农业部的农户固定观察点数据,利用数理模型对吉林省农户土地规模-生产率之间的关系进行了验证。结果表明:(1)农户土地规模-土地生产率之间的关系并不是简单的直线关系,当农户经营的土地面积小于30亩时,负向关系并不明显,但农户经营土地的规模超过30亩后,两者之间则呈现出明显的负向关系;(2)吉林省大规模农户土地产出率较低的主要影响因素为化肥投入,劳动投入因素的影响位列次席,这与前人的研究有所差别;(3)农户劳动力的影子工资率与农户土地规模存在正向关系。鉴于目前吉林省大部分农户的经营规模在20亩以下,因此笔者建议鼓励土地流转,进一步推动耕地的适度经营规模;大规模农户可适当地增加化肥和劳动投入量。     

Negotiating Technology — (Re)considering the Use of GIS by Indigenous Peoples

Geographic Information Systems (GIS) have been increasingly touted for their ability to help empower indigenous peoples. The opportunity to discuss the development of an iwi‐based GIS with Te Ruunanga O Raukawa provides a platform for reflecting critically on issues that impact the effective use of GIS by indigenous groups. The dialectical context of GIS is explored by (re)considering the opportunities and challenges of applying GIS as a cross‐cultural communication device. A position is negotiated which interprets GIS as conditionally empowering provided that indigenous peoples consider their symbolic representation in, and physical access to GIS before making an initial investment in the technology.

全球地方化背景下乡村旅游地治理模式转变与发展要素互动——以四川省成都崇州市竹艺村为例

全球地方化背景下如何通过旅游治理发挥要素优势成为实现乡村可持续发展的关键问题。以四川省竹艺村为例,从发展要素视角探析从LOT（Lease-Operation Tourism）模式到LOT-CBT（Community-Based Tourism）融合模式转变中乡村旅游发展要素的互动机制。研究发现：① 旅游治理模式决定了发展要素的互动关系,要素的互动关系亦推进了旅游治理模式的转变,两者之间呈现循环往复的作用路径;② 不同主体对发展要素的利用与整合能力存在差异导致其从旅游业中获益程度不同;③ 不同旅游治理模式融合下竹艺村形成了竹艺村-乡村企业-农户家庭层层嵌套的3层旅游发展层级;④ 社工的进驻推进了模式融合和发展要素的层级间流动,实现了2种模式优势叠加。     

Toward an inclusive semantic interoperability: the case of Cree hydrographic features

There has been ample work in GIScience on the formalization of ontologies but a relatively neglected area is the influence of language and culture on ontologies of geography. Although this subject has been investigated for conceptual ontologies using indigenous words denoting geographic features, this article represents the first attempt to develop a logical ontology with an indigenous group. The process of developing logical ontologies is here referred to as formalization. A methodology for formalizing ontologies with indigenous peoples is presented. A conceptual (human readable) ontology and a logical (axioms specified in mathematical logic) ontology were developed using this methodology. Research was conducted with the Cree, the largest indigenous language grouping in Canada. Results show that the geospatial ontology developed from Cree geographic concepts possesses unique design considerations: no superordinate classes were found from archival sources or Cree speakers so ontologies are structurally flat; the ontology contains some unique classes of water bodies; and the ontology challenges our notions of the generalizability of ontologies within indigenous groups. Whereas these difficulties are not insurmountable to the establishment of a cross-cultural Geospatial Semantic Web, the current plans of the World Wide Web Consortium do not adequately address them. We suggest future directions toward an inclusive semantic interoperability.     

中国省域城镇工资水平的区域分异机制与空间效应

工资水平的区域分异是一种较为常见的经济地理现象,其形成源自于众多影响因素的综合作用,生成与演进也带有特定的区域相互作用特征。运用空间计量分析与GIS相结合的方法,系统分析我国省域城镇现有工资水平的区域分布特征及分异格局,进一步深入探讨中国工资水平区域分异的作用机制和空间效应。在对中国工资水平区域分异的基本现状进行简要描述的基础上,利用新经济地理学中的工资方程,结合中国经济社会发展实际,试图阐明中国工资水平现有分异格局的作用机制;并通过全域自相关指数、SLM和SEM模型实证检验了各主要理论因素对中国工资水平区域分异的影响程度及其空间效应,结果显示：市场潜能、开放度、市场分割度等因素对中国工资水平的区域分异有重要的影响,且中国省域间城镇工资水平存在显著的空间误差效应。最后,从合理缩小现有的工资水平区域差距,促进区域协调发展的角度提出了若干政策建议,具体包括健全劳动力市场协调机制、减少劳动力资源的跨区域流动障碍;强化人力资本积累在缩小地区工资差异中的作用力;增进省级地域单元间的贸易联系性,弱化市场分割程度;优化低工资地区的外贸投资环境,提升其对外贸易竞争力和融资效率;推进东部地区尽快转型升级,积极培育中西部省份重要的增长极。     

The geography of dual career households: a research agenda and selected evidence from secondary data sources for Britain

"Amongst the key dimensions of population and labour market change in most parts of western Europe and other similar economies in the 1990s are low fertility rates, rising numbers of smaller households, increasing female participation rates, growth in higher level non-manual occupations and the spread of flexible employment patterns. This paper explores how these trends have led to an increase in the number and significance of one particular subgroup: dual career households. An overview from available secondary sources of the geography and socio-economic characteristics of such households in Britain is presented, and directions for possible future research on dual career households are outlined."     

Rethinking Precolonial Plant Cultivation on the Northwest Coast of North America

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.

Response of reindeer and caribou to human activities

Petroleum and mineral exploration and extraction, hydroelectric development, atmospheric transport of contaminants, timber harvesting and tourism are increasing worldwide, especially in the Arctic. This development may adversely affect populations of reindeer/caribou ( Rangifer tarandus ) which are the basis of subsistence economies for northern indigenous peoples. Our purpose is to present a survey of the literature that has investigated the response of reindeer/caribou to human activities. Individuals and groups of reindeer/caribou: 1) move away from point sources of disturbance; 2) increase activity and energy expenditure near disturbance; 3) delay crossing or fail to cross linear structures; 4) shift away from areas of extensive and intensive development; and 5) are killed by collisions with vehicles and by hunting along roads. Cows and calves during the calving season are the most easily disturbed group. Bulls in general and all reindeer/caribou during insect harassment are least likely to avoid development areas. Estimation of the proportion of a population that is exposed to disturbance and the implications of this exposure to annual energy budgets, survival and productivity of reindeer/caribou has received little attention. Future advances in understanding the implications of human disturbance to reindeer/caribou will require cumulative effects assessment at annual, population and regional scales. Although some level of cumulative effect is likely, clear separation of cumulative effects of development from natural variation in caribou habitat use and demography will be difficult.     

Farmers’ Dual Roles in Food Safety:Perceptions and Countermeasures

Farmers are both the producers and consumers of food, and as such have a dual role in food safety: they both generate risks and are exposed to them. Based upon a survey of the food production and consumption habits of 140 farm households and long-term research in two villages in Yunnan province, this study found that rural families are highly dependent on the market for food production and consumption. In their role as consumers, farmers are aware of food safety risks and concerned about them, but their ability to protect themselves is limited. They do so primarily by avoiding certain products and growing as much of their own food as possible. At the same time, in their role as producers, farmers engage in practices, primarily the overuse and inappropriate use of fertilizer and pesticides, that are damaging to food safety and the environment. There is therefore a disconnect in their roles as consumers and producers that needs to be addressed if policy goals for improving food safety and reducing the use of agricultural chemicals are to be achieved. Farmers need more information about food safety risks related to the products they consume themselves, and technical guidance on the safe use of farm chemicals when growing food for market. However, such measures will not be effective unless the external pressures on farmers are also addressed, through consideration of market incentives to use farm chemicals and the impact of consumer demand.

Segregation and diversity measures are meant to reflect extent of integration. Based on population counts gathered for enumeration units, these areal-based measures are sensitive to the spatial scale at which the data are tabulated. They are also not effective in capturing various types of assimilation affected by spatial distance among ethnic groups. This paper proposes to use the multiethnic household as a measure of ethnic integration and social assimilation. Using 1990 Public Use Microdata Samples (PUMS), the percentage of multiethnic households is derived for each state and Public Use Microdata Area (PUMA) to indicate integration. Based upon the results, Hawaii and Alaska have extremely high levels of integration. The west and southwest are more integrated than the rest of the U.S., with the exceptions of Oklahoma and several states along the east coast. The least integrated region includes several Appalachian states. The PUMA-level analysis reveals a great deal of variation in ethnic integration within states.     

Race,Gender, and Spatial Segmentation in the Twin Cities*

This study analyzes commuting trends in a relatively vibrant setting during the 1980s to determine (a) how labor market segmentation correlates with differences in the spatial dimensions of local labor markets, and (b) whether this link represents a direct spatial effect, independent of earnings, travel mode, and part-time work. I use 1980 and 1990 PUMS data to analyze changes in racial and gender divisions in the workforce, and I develop an estimate of work trip distance to adjust for different travel modes. For all groups except white men, employment in a job “typical” of one's gender and racial group is associated with more localized commutes, but this effect is strongly mediated by variations in earnings and part-time work. Using a covariance structure model to control for these effects, I find no independent link between segmentation and longer commutes among African Americans. Earnings and commute distances remained unchanged over the decade for African Americans, providing no evidence of a purely spatial mismatch manifest in lengthening work trips without corresponding wage gains. The spatial dimensions of an employment mismatch for inner-city minorities are concealed through the replacement of production jobs by poorly paid service work in the expanding downtown economy of a vibrant regional center.

Making a living in the cocoa frontier,Western Ghana: Diversifying incomes in a cocoa economy

Geografisk Tidsskrift, Danish Journal of Geography 107(2):29–44, 2007

The literature on livelihoods in rural Africa has for the past decade documented and discussed the growing importance of non-farm income for rural livelihoods and often linked this to an increasing divorce of rural livelihoods from farming and land. This paper challenges the view that the increasing importance of income earned on non-farm activities is a direct expression of processes of deagrari-anisation. Drawing on empirical evidence from recent research in the Ghanaian cocoa frontier, the paper shows that a growing importance of income from non-farm activities is evident, but that incomefrom cocoa is still the determining factor for most households' income and thereby for the demand for non-farm goods and investment in the non-farm sector. By identifying two overall factors explaining the level of income diversification, the paper questions how generally applicable processes of deagrarianisation are in the Ghanaian case. Firstly, the actual crop cultivated and its price and marketing possibilities are of great importance for a farmer's choice to engage and stay in the agricultural sector or to diversify into non-farm activities. Secondly, different dynamics are evident between settlements dominated by either migrant or indigenous households, mainly due to unequal access to land. The paper argues that what on a general scale may look like processes of deagrarianisation during the last decade to a large extent can be explained by migrants without access to land who engage full-time in the nonfarm sector and by cocoa farmers diversifying their incomes, but not leaving a deteriorated agriculture.
