Optimization of the charcoal chain in Tanzania
The high reliance on charcoal makes Tanzanian producers, traders and consumers vulnerable for environmental problems such as deforestation. Increasing the sustainability of the charcoal chain in Tanzania calls for a comprehensive approach that accounts for a multitude of aspects (e.g technological, economic, social and environmental issue
Acceptability of Condom Promotion and Distribution Among 10-19 Year-Old Adolescents in Mpwapwa and Mbeya Rural Districts, Tanzania.
\ud
The HIV/AIDS pandemic remains a leading challenge for global health. Although condoms are acknowledged for their key role on preventing HIV transmission, low and inappropriate use of condoms persists in Tanzania and elsewhere in Africa. This study assesses factors affecting acceptability of condom promotion and distribution among adolescents in Mpwapwa and Mbeya rural districts of Tanzania. Data were collected in 2011 as part of a larger cross-sectional survey on condom use among 10-19 year-olds in Mpwapwa and Mbeya rural districts of Tanzania using a structured questionnaire. Associations between acceptability of condom promotion and distribution and each of the explanatory variables were tested using Chi Square. Multivariate logistic regression model was used to examine independent predictors of the acceptability of condom promotion and distribution using STATA (11) statistical software at 5% significance level. Mean age of the 1,327 adolescent participants (50.5% being males) was 13.5 years (SD = 1.4). Acceptance of condom promotion and distribution was found among 37% (35% in Mpwapwa and 39% in Mbeya rural) of the adolescents. Being sexually active and aged 15-19 was the strongest predictor of the acceptability of condom promotion and distribution (OR = 7.78, 95% CI 4.65-12.99). Others were; not agreeing that a condom is effective in preventing transmissions of STIs including HIV (OR = 0.34, 95% CI 0.20-0.56), being a resident of Mbeya rural district (OR = 1.67, 95% CI 1.28-2.19), feeling comfortable being seen by parents/guardians holding/buying condoms (OR = 2.20, 95% CI 1.40-3.46) and living with a guardian (OR = 1.48, 95% CI 1.08-2.04). Acceptability of condom promotion and distribution among adolescents in Mpwapwa and Mbeya rural is low. Effect of sexual activity on the acceptability of condom promotion and distribution is age-dependent and was the strongest. Feeling comfortable being seen by parents/guardians buying or holding condoms, perceived ability of condoms to offer protection against HIV/AIDS infections, district of residence and living arrangements also offered significant predictive effect. Knowledge of these factors is vital in designing successful and sustainable condom promotion and distribution programs in Tanzania.\u
Yield loss due to the stemborer Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) at different nitrogen application rates to maize
International Journal of entomology, 2006; 42(3-4):487-494Field trials were conducted at Kibaha and Morogoro in eastern Tanzania during two seasons
to evaluate the effect of nitrogen fertilization (0, 50, 75, 100 kg [N]/ha) on pest abundance, plant
damage and yield loss of maize due to stemborers. In general, ear and grain weights increased
linearly with nitrogen level. In the infested plot, grain weight increased 2.5 and 1.8 fold from 0 to
100 kg [N]/ha in the short and long rainy season, respectively, at Kibaha, and 1.4 and 1.6 times at
Morogoro. Yield loss decreased with an increase in nitrogen application and the effect was stronger
under high than low borer infestation levels. The results show the benefi cial effect of nitrogen on the
plant’s ability to compensate for borer damage. Analysis of economic benefi ts of applying fertilizer and
insecticide treatment indicated that using insecticides is not profi table under high-pest-low-soil fertility
conditions

Greening the charcoal chain in Tanzania
With a population of 34 million and an extremely high reliance on charcoal, Tanzania is a classic example of the social and environmental risks faced by many developing countries. About 85% of the total urban population uses charcoal for household cooking and energy provision for small and medium enterprises (Sawe 2004). In 1992 the total amount of charcoal consumed nationwide was estimated to be about 1.2 million tons (Sawe 2004). In 2002, the charcoal business generated revenues of more than 200 billion TShs (US$ 200 million), with more than 70 000 people from rural and urban areas employed in the industry (TaTEDO 2002b). Dar es Salaam, Tanzania’s largest city, accounts for more than 50% of all charcoal consumed in the country. The charcoal sector is far from sustainable. The forest resources that the industry is relying on are disappearing rapidly and the productivity of the sector has not seen any improvement either. The charcoal sector in Tanzania is operating economically, socially and environmentally in a suboptimal manner. However, solutions that safeguard the charcoal sector’s future are not straightforward
