ABSTRACTLake Victoria fisheries are important to Tanzanian food security, employment, and foreign exchange, but they have experienced declining performance, largely due to overfishing. This paper studies technical efficiency and skipper skill using Tanzanian fishery data for the two major species, Nile perch and dagaa. The relative level of efficiency is high in both fisheries and several observable variables linked to skipper skill significantly explain the efficiency level.

AbstractAgriculture is the backbone of many African economies. Cilliers explores the history and role of agriculture in development, and the likely future trajectory of agriculture in Africa along the Current Path, drawing lessons from other regions. Improvements in this sector, particularly access to finance and use of modern technology can unlock the significant potential to achieve food security, improve health and nutrition outcomes, create agribusiness ventures that influence employment, earn foreign exchange through exports and promote economic prosperity. The chapter concludes with a scenario that emulates the impact of a revolution in agriculture on food security and growth.

Abstract Lake Victoria fishery activities are of crucial economic importance to the communities around East Africa as they support the majority of fishers specifically through Nile perch fishing. As a consequence, increasing fishing pressure had also led to overfishing. This study employed the Data Envelopment Analysis (DEA) and Propensity Score Matching (PSM) techniques to assess the impact of Nile perch overfishing on technical efficiency of fishers based on a survey of 268 fishers across 10 landing sites in Lake Victoria, Tanzania. Results from the DEA show that, overall Nile perch fishers have average technical efficiency of 30% which indicates a high level of inefficiency. Specifically, there is no statistically significant difference in the technical efficiencies for Nile perch fishers who are overfishing and those who are not overfishing due to fisher’s mobility across the Lake. In addition, mode of propulsion and being a member of fishery organization were found to be statistically significant factors influencing inefficiency of Nile perch fishers. Furthermore, results from the probit estimates of the PSM show that being a member of fishery organization, quantity of Nile perch harvested per trip, age of a fishing vessel (boat), the gillnet mesh size and cost of fishing inputs have statistically significant effect in influencing the probability of Nile perch overfishing. However, further result indicates that Nile perch overfishing do not have statistically significant impact on fisher’s technical efficiency. Therefore, this study recommends a need to monitor and formalize fisher’s mobility as one of the alternative for co-management of the Lake. Also, overfishing can be controlled without necessarily affecting technical efficiency of Nile perch fishers through training and access to proper fishing gears.

The challenge of food security in Nigeria hinges on several factors of which poor technical efficiency is key. Using a stochastic frontier framework, we estimated the technical efficiency of agricultural households in Nigeria and tested for the significance of mean technical efficiency of food-secure and food-insecure agricultural households. We further assessed the determinants of agricultural households’ inefficiencies within the stochastic frontier model and adopted a standard probit model to assess the determinants of households’ food security status. The results of our analyses revealed that; on the overall, the agricultural households had a mean technical efficiency of 52%, suggesting that agricultural households have the tendency of improving their technical efficiency by 48% using the available resource more efficiently. We found that households that are food-secure are more technically efficient than food in-secure households and this was significant at one-percent. Our results provide useful insights into the role of land size and number of assets as determinants of agricultural households’ food security and technical efficiency status.

The economic growth, which is underway in Russia, raises new questions to be addressed. How to improve the quality of growth, increasing the role of new competitive sectors and transforming them into the driving force of growth? How can progressive structural changes be implemented without hampering the rate of growth in general? What are the main external and internal risks, which may undermine positive trends of development? The author looks upon financial, monetary and foreign exchange aspects of the problem and comes up with some suggestions on how to make growth more competitive and sustainable.

Relevance. Grain is the key to strategic products to ensure food security. From this point of view, the creation of large grain farms is a matter for the country's selfsufficiency and it leading to a decrease in financial expense for import. Creation of such farms creates an abundance of productivity from the area and leads to obtaining increased reproductive seeds. The main policy of the government is to minimize dependency from import, create abundance of food and create favorable conditions for export potential.The purpose of the study: the development of grain production in order to ensure food security of the country and strengthen government support for this industry.Methods: comparative analysis, systems approach.Results. As shown in the research, if we pay attention to the activities of private entrepreneurship in the country, we can see result of the implementation of agrarian reforms after which various types of farms have been created in republic.The role of privateentrepreneurshipinthedevelopmentofproduction is great. Тhe article outlines the sowing area, production, productivity, import, export of grain and the level of selfsufficiency in this country from 2015 till 2017.

Oral History Interviews

Food insecurity in Indigenous communities in Canada continue to gain increasing attention among scholars, community practitioners, and policy makers. Meanwhile, the role and importance of Indigenous foods, associated knowledges, and perspectives of Indigenous peoples (Council of Canadian Academies, 2014) that highlight community voices in food security still remain under-represented and under-studied in this discourse. University of Winnipeg (UW) researchers and Fisher River Cree Nation (FRCN) representatives began an action research partnership to explore Indigenous knowledges associated with food cultivation, production, and consumption practices within the community since 2012. The participatory, place-based, and collaborative case study involved 17 oral history interviews with knowledge keepers of FRCN. The goal was to understand their perspectives of and challenges to community food security, and to explore the potential role of Indigenous food knowledges in meeting community food security needs. In particular, the role of land-based Indigenous foods in meeting community food security through restoration of health, cultural values, identity, and self-determination were emphasized by the knowledge keepers—a vision that supports Indigenous food sovereignty. The restorative potential of Indigenous food sovereignty in empowering individuals and communities is well-acknowledged. It can nurture sacred relationships and actions to renew and strengthen relationships to the community’s own Indigenous land-based foods, previously weakened by colonialism, globalization, and neoliberal policies.
