MENVSC / Department of Geography and Geo-Information Sciences / The purpose of this study was to contribute towards a better understanding of the effectiveness of Biosphere Reserve as a tool in managing natural resources in the Vhembe District Municipality (VDM), Limpopo Province of South Africa. There are limited documented materials for a better understanding of the effectiveness of Biosphere Reserve (BR) as a tool in managing natural resources in the Vhembe District Municipality (VDM). As a result, this study was undertaken to bridge this gap and to discover new insights to assist in understanding the effectiveness of BR as a tool in managing natural resources. This study adopted a pragmatic research approach, which is a mixture of the qualitative and quantitative research approaches, wherein data were collected using primary and secondary sources. Both primary and secondary data were used, in order to obtain information concerning the effectiveness of biosphere reserve in the study area. Primary data were obtained using a combination of methods, including participatory rural appraisal (PRA) tools and techniques, and informal and formal surveys. The secondary data was collected from desk-based examination of relevant documentation relating to conservation of the Biosphere Reserves areas. The documents included previous reports from Greenest Municipality Competition (GMC) results for all local municipalities from 2012 to 2017, Management Effective Tracking Tool (METT-SA) from 2016 to 2018, and previous research data on conservation. The results obtained revealed that Biosphere Reserve (BR) is an effective tool for the conservation of natural resources within Vhembe District, South Africa. This is because natural resources are taken into consideration when there are developments and projects being undertaken. Furthermore, the communities in Vhembe District Municipality benefit from the programmes and projects aimed at conserving natural resources within the VBR. The study also revealed that there are environmental challenges within the Vhembe Biosphere Reserve due to mining activities, climate change, developments in natural resources and deforestation, which require the enforcement of by-laws and programmes and projects aimed at conserving natural resources. / NRF

Die vorliegende Dissertation widmet sich methodischen und empirischen Forschungsfragen mit Bezug auf saisonale Arbeitsmärkte und Politiken zur nachhaltigen Nutzung natürlicher Ressourcen. Hierfür wird ein gesamtwirtschaftlicher Modellierungsansatz angewendet, für den das im südöstlichen Himalaya gelegene Königreich Bhutan als empirische Fallstudie dient. Das methodische Forschungsziel der Arbeit ist, die Relevanz der Darstellung von saisonalen Arbeitsmärkten innerhalb von allgemeinen Gleichgewichtsmodellen (sog. CGE Modelle) zu ergründen. Dies stellt eine Neuheit in der Literatur dar. Die Arbeit zeigt auf, dass Modelle ohne saisonale Arbeitsmärkte systematisch Ergebnisse, wie Angebotsreaktionen und Wohlstandseffekte, verzerren. Die Saisonalität von Arbeit hat eine hohe Relevanz für gesamtwirtschaftliche Analysen im Kontext landwirtschaftlich geprägter Volkswirtschaften, insbesondere für Untersuchungen des Strukturwandels und agrarpolitischer Interventionen. Empirisch wird die wechselseitige Abhängigkeit von Politiken zum nachhaltigen Management natürlicher Ressourcen mit Zielen des Umweltschutzes und der ländlichen Entwicklung untersucht. Basierend auf unterschiedlichen Modellierungsansätzen, konzentrieren sich drei Studien auf agrar- und forstpolitische Szenarien in Bhutan. Es wird gezeigt, dass Bhutans Ziel, seinen landwirtschaftlichen Sektor auf 100% ökologische Landwirtschaft umzustellen, zu substantiellen Wohlfahrtsverlusten und negativen Folgen für die Ernährungssicherung führen würde. Die Analyse verschiedener forstpolitischer Szenarien demonstriert, dass eine höhere Forstnutzung in Bhutan im Sinne der gesamtwirtschaftlichen und ländlichen Entwicklung nachhaltig möglich ist. Die Arbeit weist auf verschiedene zukünftige Forschungsfelder hin, wie zum Beispiel die Integration von Ökosystemdienstleistungen, was als eine der wesentlichen Einschränkungen bei der modellgestützten Analyse von Politiken zur Nutzung natürlicher Ressourcen identifiziert wurde. / Using an economy-wide modelling approach, this dissertation investigates methodological and empirical research questions related to seasonal labour markets and natural resource policies. The Kingdom of Bhutan, located in the south-eastern Himalayas, serves as a case study. The methodological research objective of this thesis is to gain an understanding of the relevance of seasonal labour markets in the context of economy-wide modelling. The depiction of seasonal labour markets at national scale using a seasonal social accounting matrix (SAM) and computable general equilibrium (CGE) model presents a novel development within the literature. It is demonstrated, that the absence of seasonal labour markets leads to systematic bias of model results. The consequences are distorted supply responses and biased welfare effects, underlining the pivotal implications of seasonality for economy-wide analysis in the context of agrarian economies, particularly for scenario analysis involving structural changes and agricultural policy interventions. The empirical research objective addresses the interdependence of natural resource policies with objectives of environmental conservation and rural development. Employing modelling techniques, three studies focus on specific agricultural and forest policy scenarios in Bhutan. Simulating Bhutan’s ambitious policy objective to convert to 100% organic agriculture demonstrates substantial welfare losses and adverse impacts on food security, causing trade-offs with objectives of rural development and food self-sufficiency. Analysing forest policy reforms shows that increased forest utilization contributes to economic development, particularly in rural areas, without jeopardizing the country’s forest conservation agenda. The dissertation points at numerous areas of future research, as for example the incorporation of ecosystem services, which is identified as one key limitation of economy-wide analysis of natural resource policies.
