The performance and determinants of rice export in Tanzania: a vector error correction analysis
(Agricultural Economics Society of Tanzania, 2021) Luhwago, W.; Philip, D.; Kadigi, R.; Kangile, J.R.; Kazuzuru, B.; Hella, J.; Mgeni, C.P.
The performance of rice export in Tanzania is inadequate despite the country being the leading rice producer in the East African Community (EAC) region. Extensive government interventions in the sector and existence of inward-looking trade policies such as Common External Tariff within EAC region were expected to increase rice exports especially intra-regional trade. The question is why the country is performing poorly in terms of rice exports despite all the efforts and the favourable environment for rice production. To answer this question, the present paper analyses the determinants of rice exports in Tanzania. Specifically, it focuses on examining the influence of price and non-price factors on rice export and assessing the competitiveness of Tanzanian exported rice. The paper uses secondary data collected from government institutions and other international data repositories. Vector Error Correction Model was used to capture the dynamics of rice export in Tanzania while the competitiveness of rice exported is assessed using Revealed Comparative Advantage Model. Results show that, international rice price, quantity produced and average GDP per capita of Kenya, Rwanda, Uganda and Burundi are the key determinants for rice export performance in the country. Rice exported is found to be less competitive within EAC regional market. The paper recommends that the government should increase production to improve rice export performance and achieve competitiveness. This will help to meet the export demand of rice to the neighbouring countries and EAC region
Ratification of the Ramsar convention and sustainable wetlands management: Situation analysis of the Kilombero Valley wetlands in Tanzania
(Academic Journals, 2011) Mombo, F.; Speelman, S.; Huylenbroeck, G. V.; Hella, J.; Pantaleo, M.
In recent years, the Kilombero Valley wetlands in Tanzania was designated and added to the Ramsar convention’s list in an attempt to improve its social, economic and environmental values. This study, carried out in selected sites within the Kilombero Valley wetlands, uses a participatory approach to analyze the existing situation and to reflect upon the quest for sustainable management as defined by Ramsar convention. The empirical findings reveal that the Kilombero Valley wetlands are an important source of livelihood for 87% of the dwellers in the area. Moreover, the wetlands also contribute significantly to welfare outside the area as 70% of the country’s hydropower depends on water regulation functions of this wetland and they are the source of a diverse number of streams, adding to their biological and ecological value. The study furthermore revealed that the current institutional arrangement for the site threaten the sustainability of the wetlands, despite its addition to the Ramsar convention’s list. A more detailed study on appropriate incentive mechanisms for the sustainable management of the wetlands, which would help to internalize the negative effects created by the users, is recommended.
