A comparative analysis of technical efficiency of smallholder tobacco and maize farmers in Tabora, Tanzania

The study presented here considers the relative efficiency of planting tobacco and maize in the tobacco-producing Tabora region of Tanzania. The study used a 2013 survey that was conducted among smallholder farmers in the Tabora region. The aim was to investigate whether farmers are better off planting tobacco or maize. The paper briefly reviews the importance of agriculture in general and tobacco planting in particular on the Tanzanian economy. The paper then reviews the methodology used in the analysis, The Frontier Production Function.


Partnerships between private sector ecotourism operators and local communities in the Okavango Delta, Botswana: A case study of the Okavango Community Trust and Wilderness Safaris partnership

The majority of Africa is characterised by high levels of poverty, high population densities and limited economic development. Botswana is, however, different in having the highest gross domestic product per capita in Africa, relatively low population densities and high levels of socio-economic development. Inequality, however, remains high. A community-based natural resource management programme was introduced in 1989 to ensure that local communities benefit from the country's abundant natural resources, with the hope that they will then protect them.


Who should set the total allowable catch? Social preferences and legitimacy in fisheries management institutions

This article presents a decision-making model based on situations that are typically encountered in fisheries management when setting the total allowable quota. The model allows assessing the differences in outcomes when different management institutions make the decision under uncertain conditions. Social preferences are considered to measure the social expected costs raised by different institutions.


Land Acquisitions in Tanzania: Strong Sustainability, Weak Sustainability and the Importance of Comparative Methods

This paper distinguished different analytical approaches to the evaluation of the sustainability of large-scale land acquisitions—at both the conceptual and methodological levels. First, at the conceptual level, evaluation of the sustainability of land acquisitions depends on what definition of sustainability is adopted—strong or weak sustainability. Second, a lack of comparative empirical methods in many studies has limited the identification of causal factors affecting sustainability.
