Impact of climate variability and change adaptation strategies on technical efficiency of sorghum production in Manyoni District, Tanzania
(Tanzania Journal of Agricultural Sciences, 2023) Mbwambo, E. P.; Kabote, S. J.; Kazuzuru, B.
Climate variability and change adaptation strategies are increasingly becoming fundamental for improving efficiency in agricultural production in Tanzania and elsewhere in developing countries. However, empirical evidence on how adaptation strategies improve agricultural technical efficiency on drought resistant varieties like sorghum is inadequate in Tanzania. This study was conducted to address this knowledge lacuna in the literature. With cross-sectional research design, we used a household survey to collect data from 330 randomly selected household heads. A Cobb- Douglas stochastic frontier model was used to determine the impact of adaptation strategies on technical efficiency of sorghum production. Farmers adapted a number of strategies including drought tolerant crops, conservation agriculture, drainage system, early maturing crops, use of hired labour, resistant livestock breeds, membership in farmer organizations, access to extension services, and access to credit to cushion climate variability and change impact. Six strategies including use of drought tolerant crops, drainage systems, conservation agriculture, membership in farmer organizations, access to extension services and access to credit showed significant impact on technical efficiency of sorghum production at 5% level of significance. Such strategies were effective in improving technical efficiency of sorghum production. However, about half of the respondents were less efficient. Therefore, farmers’ adaptation strategies were indisputably essential in semi-arid environments like Manyoni district. Nevertheless, a policy to heighten use of the effective farmers’ adaptation strategies to cushion climate variability and change impact should be devised and effectively executed to strengthen farmers’ efficiency.
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
