Show moreThis thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe. The focus is predominantly on the Grey Crowned Crane although one chapter is dedicated to social dimensions of Wattled Crane conservation. Chapter 2 provides an overview of how social factors influence wetland management decision-making, drawing linkages between human actions and ecological changes associated with crane habitat loss. Chapter 3 outlines major human actions that impact Wattled Cranes and their habitats, elaborating the underlying social causations behind the actions. Chapter 4 draws lessons on the effectiveness of community-led conservation approaches through an evaluation of a community-led project in Kenya. Chapter 5 presents results of an evaluation of the institutional development process and the ensuing environmental conservation impacts at three sites where conservation projects were initiated in 2002 in Uganda. Chapter 6 synthesises key findings, addressing the question of what works for cranes and wetland conservation in rural landscapes in East and Southern Africa. The thesis contributes to an improved understanding of interactions between cranes and rural communities and provides insights into strategic approaches for addressing the decline of cranes within their range in East and Southern Africa.

Show moreBACKGROUND: A clear understanding of the differences in the epidemiology of food allergy between rural and urban populations may provide insights into the causes of increasing prevalence of food allergy in the developed world.OBJECTIVE: We used a standardized methodology to determine the prevalence and types of food-specific allergic sensitization and food allergies in schoolchildren from urban and rural regions of China, Russia, and India.METHODS: The current study is a multicenter epidemiological survey of children recruited from 5 cities in China (Hong Kong and Guangzhou), Russia (Tomsk), and India (Bengaluru and Mysore) and 1 rural county in Southern China (Shaoguan). A total of 35,549 children aged 6 to 11 years from 3 countries participated in this survey. Random samples of children from 3 countries were first screened by the EuroPrevall screening questionnaire. Children with and without a history of adverse reactions to foods were then recruited for the subsequent case-control comparative studies. We determined the prevalence rates of food-specific IgE sensitization and food allergies using the predefined criteria.RESULTS: The prevalence rates of food-specific IgE sensitization (>= 0.7 kU/L) to at least 1 food were 16.6% in Hong Kong, 7.0% in Guangzhou, 16.8% in rural Shaoguan, 8.0% in Tomsk, and 19.1% in India. Using a definition of probable food allergy as reporting allergic symptoms within 2 hours of ingestion of a specific food plus the presence of allergic sensitization to the specific food (positive IgE and/or positive skin prick test result), the prevalence of food allergy was highest in Hong Kong (1.50%), intermediate in Russia (0.87%), and lowest in Guangzhou (0.21%), Shaoguan (0.69%), and India (0.14%). For children recruited from Hong Kong, both sensitization and food allergy were significantly higher in children who were born and raised in Hong Kong when compared with those who were born in mainland China and migrated to Hong Kong, highlighting the importance of early-life exposures in affecting the subsequent development of food sensitization and food allergy.CONCLUSIONS: There are wide variations in the prevalence of food-specific IgE sensitization and food allergy in the 3 participating countries. Food allergy appears to be less common when compared with developed countries. The variations in the prevalence of food allergen sensitization cannot be explained by the differences in the degree of urbanization. Despite the high prevalence of food-specific IgE sensitization in India and rural China, food allergy is still extremely uncommon. In addition to IgE sensitization, other factors must play important roles resulting in the clinical manifestations of food allergies.

Show moreIn het gebied tussen de Oude Rijn en de Nieuwe Maas in de huidige provincie Zuid-Holland bevond zich gedurende de eerste drie eeuwen van onze jaartelling het bestuursdistrict van de rurale gemeenschap van de Cananefates (de civitas Cananefatium). De vorming van deze gemeenschap, alsmede de veranderingen die binnen de identiteit van deze groep plaatsvonden zijn onderzocht door middel van een systematische analyse van de aanwezige archeologische resten. Om de rol van de Romeinse staat in deze processen te duiden, zijn ook de stedelijke en militaire gemeenschappen in de analyse betrokken. Op deze manier is een overzicht ontstaan van een landschappelijke en administratieve regio waarbij aspecten als de interactie tussen de verschillende groepen, het karakter van de rurale gemeenschappen en het contrast met andere rurale groepen langs de grenzen van het Romeinse rijk bestudeerd konden worden.

Show moreThe main objective of this thesis is to improve understanding of the role of helminth infections in the development of insulin resistance (IR), hence Type 2 Diabetes (T2D), in the light of increasing urbanization in Indonesia. Our large-scale cluster-randomized controlled trial was performed in a rural area of Indonesia, which is endemic for soil-transmitted helminth (STH), and has been previously reported to have a low prevalence of IR and T2D. In STH-infected subjects, as assessed by microscopy, 12-month anthelmintic treatment increased IR, which was mediated by an increase in BMI and leptin to adiponectin ratio, as well as reduction in eosinophil count. Next, we also aimed to assess the different metabolic profile between populations living in rural and urban area, and to study the relative protective effect of rural environment to high-fat diet (HFD). In comparison to those living in rural area, individuals living in urban area had higher whole body IR, which was mainly mediated by the higher adiposity and leptin level, which were progressively increased with increased duration of time spent in urban area. Different environmental factors (including past or current exposure to STH) did not seem to affect the metabolic response to HFD intervention, independent from adiposity. Show less

Show moreThis chapter starts from the premise that economic actions can only be understood if looked upon as embedded in social structure. Therefore, it elaborates the concept of (sustainable) livelihood, which is taken to emanate from the interactions of actors with vital capitals. It argues that, in the context of globalization, livelihood becomes increasingly multidimensional and multilocal, spanning rural and urban areas at the same time. The chapter focuses on changing rural-urban linkages in West Africa, notably on the trade in maize, yam, and cattle in Benin. Expanding flows between rural areas and urban outlets are analysed against the background of the livelihood strategies of traders, paying special attention to trade organization, networks, entry modes, and accumulation paths. Emphasis is placed on the role of social capital in these interactions. Bibliogr. [ASC Leiden abstract] Show less

Show moreThe 1980s were a dramatic period in the history of South Africa. At stake in the battles of the 1980s was the contest about changing the borderlines in the racial and social stratifications of the country. In this contest, participants developed their own visions of a future society, of a new political and social order as well as a new moral order. This book examines these processes at the local level. It focuses on the United Democratic Front (UDF) as a social movement from below, officially launched in August 1983. The aim of the UDF was the creation of a united democratic South Africa. The author takes three local organizations as a vantage point. The first part of the book briefly explores the origins of the UDF, followed by a chronological outline of major events and trends in the 1980s. The second part consists of three case studies, which look in detail at locally based attempts at shaping a new society: a youth congress in Sekhukhuneland, a rural part of Lebowa in the Northern Transvaal; a civic association in Kagiso, a township west of Johannesburg; and 'Grassroots', a community newspaper in the Cape Peninsula. The conclusion describes how these local struggles fit into the overall story of the antiapartheid struggle Show less

Show moreMany local tenure arrangements in Niger were largely implicit, not recorded in any codified form. In the process of codification now underway, chiefs are regarded as the key interpreters of tradition, mutating the implicit into the explicit. Land tenure reform is not without contradictions. How are chiefs to maintain a level of flexibility and dynamism within the codified, rigidified form that the local tenure arrangements will have once they are made explicit? How are chiefs to determine which implicit local customary practice is to have primacy in a codified form, since their parameters are always changing from season to season and from year to year? As the new 'Code rural' in Niger shows, the invention-of-tradition approach which has gained prominence in English-language research has failed in its French counterparts. Both planner-administrators and academics are engaged in a discourse that seems to take tradition as an undisputed given. The remarkable thing is that is appears to work. The 'Code rural' has been considered path-breaking and innovative because it seeks to modernize tenure rules without breaking with tradition. The conclusion is that land tenure legislation can be modernized by integrating traditional chiefs into the legal framework. Show less

Show moreThis essay deals with the relation between ritual behaviour and environmental conditions in an African rural society, that of the South-East Surmic (Nilo-Saharan)-speaking Me'en people, a group of 'tribal' cultivators in Käfa region, Ethiopia. The study attempts to integrate 'ideational' and material-environmental elements, in order to explain how meaning in ritual is constituted in the dialectic between human action and environmental conditions. For this purpose, a text of the 'mósit', a central ritual of the Me'en, is presented and discussed. The author looks at the significance of environmental referents in the ritual acts and words, and at how the language and the context of the 'mósit' reflect social and reproductive relations within Me'en society. The aim is an explanatory account of the 'mósit' as a religious ritual system. The unifying theoretical perspective which informs this analysis is derived from the theory of E.T. Lawson and R.N. MacCauley (1990), which advocates a 'competence'-approach to religious ritual behaviour. Show less
