This study quantifies the adoption of improved amaranth varieties in Kenya and Tanzania, and the extent to which these result from international vegetable breeding research conducted by the World Vegetable Center (WorldVeg) and partners. The study used expert elicitation and a questionnaire survey among vegetable seed producers. Nine expert panels were conducted involving 123 local experts. The results show that improved amaranth varieties were planted on 51% of the planted area in Kenya and 70% in Tanzania.

This paper focuses on improved storage and preservation technologies as an adaptation strategy in response to climate change. We also study the trade-off between improved cereal storage technologies and the preservation techniques among rural households in Tanzania. We find that climate variables significantly influence farmers’ choice of improved storage technologies and preserving decisions. Using a bivariate probit model, we find that modern storage technologies and preservation measures are substitutes.

Household agricultural production for self-consumption is often highlighted by nutritionists as the main route to increasing household food security and nutritional status, especially for the poor in developing countries. At the same time, the income gains from specializing in fewer crops and selling the surplus product could be an alternate route to improved nutritional status. We use Tanzanian data to study linkages between the diversity and market orientation of a household’s agricultural production, the quality and diversity of their diets, and the nutritional status of their children.

This paper focuses on improved storage and preservation technologies as an adaptation strategy in response to climate change.

With increasingly improved cooking stoves (ICS) that aim to reduce fuelwood consumption by forest-dependent households, more evidence of what drives households to adopt ICS is needed. Using data from a representative sample (N=271) of households in a rural part of eastern Tanzania, we estimated a mixed logit model to take into account the limitations of the standard multinomial logit model and relaxed the restrictive assumption of the conditional logit model.

In this paper, we identify economic implications of the pressure to share resources within a social network. Through a set of field experiments in rural Tanzania we randomly increased the expected harvest of the treatment group by the assignment of an improved and much more productive variety of maize.

The study attempts to estimate the demand for cigarettes in Tanzania and presents simulation results on the effect of the cigarette excise tax on smoking participation, government revenue, and related topics. After briefly summarizing the magnitude and spread of cigarette consumption in the country, the paper reviews some empirical estimates from African and other countries. The 2008 Tanzanian household budget survey was used to estimate the demand for cigarettes in Tanzania.

We examine the welfare implications of the Tanzanian fisheries boom resulting from Lake Victoria Nile perch exports during 1993–2008. In the literature, there are two opposing views on the effect of fish trade: some argue that fish trade can act as an engine of growth, while others contend that trade in fish negatively affects food security, local economies and incomes of the poor.

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.

In low-income countries, both nearby local villagers, “insiders”, and non-locals, “outsiders”, extract products from protected forests even though their actions are illegal.
