Ausgangspunkt dieser Arbeit ist die gesellschaftliche Problematisierung des Größenstrukturwandels in der deutschen Landwirtschaft. Zuerst wird anhand einer strukturierenden Inhaltsanalyse von Positionspapieren zur Reform der Gemeinsamen Agrarpolitik herausgearbeitet, dass der Größenstrukturwandel sowohl als Gerechtigkeits- als auch als Multifunktionalitätsproblem gedeutet wird. Die Positionen überlappen im Prinzip der Leistungsgerechtigkeit und in dem Ziel, möglichst viele Betriebe zu erhalten. Viele der präsenten Annahmen über die Vorteile kleiner Betriebe lassen sich wissenschaftlich nicht bestätigen. Hinsichtlich sozialer Funktionen von Landwirtschaft wird eine Forschungslücke identifiziert. Es folgt eine systematische Literaturanalyse, die konzeptuelle Zugänge zu sozialen Funktionen von Landwirtschaft voneinander abgegrenzt und in einem Analyserahmen integriert. Dieser Analyserahmen berücksichtigt landwirtschaftliche Betriebe, die von ihnen ausgeübten Tätigkeiten sowie deren Wirkungen hinsichtlich sozialer Ziele (Funktionen). Aus der Literatur werden zudem elf verschiedene Typen sozialer Funktionen abgeleitet. Daran knüpft eine empirische Fallstudie an, die basierend auf umfangreichen qualitativen Daten soziale Funktionen von Landwirtschaft in Dithmarschen analysiert und Zusammenhänge mit dem regionalen Größenstrukturwandel exploriert. Die Ergebnisse deuten darauf hin, dass sich der mit dem Größenstrukturwandel verbundene, zunehmend industrielle Charakter landwirtschaftlicher Tätigkeiten sowie die abnehmende Anzahl von Landwirt/innen in ehrenamtlichen Strukturen negativ auf soziale Funktionen auswirken. Einkommensdiversifizierung gewinnt im Kontext des Größenstrukturwandels an Bedeutung und stärkt soziale Funktionen, wobei kapital- und arbeitsintensiven Tätigkeiten unterschiedlich wirken. Die Dissertation ermöglicht eine sachlichere Debatte zum Größenstrukturwandel und eine differenzierte Auseinandersetzung mit sozialen Funktionen von Landwirtschaft. / This dissertations’ starting point is the societal problematisation of the changing farm size structure in Germany. In the first article, a structuring content analysis of position papers on the post-2020 reform of the Common Agricultural Policy shows that the shift towards fewer and larger farms is framed as a problem of both equity and multifunctionality. The respective positions overlap when it comes to the principle of performance equity and the goal of maintaining as many (small) farms as possible. Many of the claims made in the debate about benefits of small farms are not supported by empirical research, and a research gap is identified, particularly regarding social functions of agriculture. The second article presents a systematic literature review. Different conceptual approaches to the social functions of agriculture are distinguished and integrated into an analytical framework. This framework considers farms, the activities they carry out and the functions that can be fulfilled through these activities. In addition, eleven different types of social functions are derived from the literature reviewed. The third article builds up on the second and presents an empirical case study, which analyses the social functions of agriculture in Dithmarschen and explores how these relate to regional structural change on the basis of an extensive qualitative data set. The results indicate that both, the increasingly industrial character of agricultural activities associated with the change in farm size structure and the decreasing number of farmers in voluntary structures have a negative impact on social functions. Income diversification becomes more important in the context of farm exits and strengthens social functions, although the effects of capital-intensive and labour-intensive activities differ. Overall, this dissertation facilitates a more objective debate on structural change and a differentiated analysis of the social functions of agriculture.

This study aims at investigating household food accessibility categories (food insecure, vulnerable, marginal and food secure) of rural households in Sekhukhune district of Limpopo province. The study is based on five wards in Mamone village in the Limpopo province of South Africa. Ten households from each ward were randomly selected for the study. Structured questionnaires administered by enumerators were used to collect information from household heads. In all 50 household heads constitutes the sample size for the study. Data was collected from 20 August 2007 to 25 August 2007. Responses in the questionnaires were tabulated, coded and processed using Statistical Package for Social Sciences (SPSS) programme. Based on comprehensive food security and vulnerability analysis the study showed that over 70 per cent of the sampled households were food insecure. Lack of education, income sources, water source, and infrastructure were some of the important factors contributing to food insecurity. The government should also give special attention to policy measures that guide towards the provision of household assets. It is recommended that special attention be given to measures that will provide the necessary factors that negatively affect household food security and vulnerability. / Agriculture, Animal Health and Human Ecology / M.A. (Human Ecology)
