Consumption Of Indigenous Fruits In Uluguru North And Ruvu North Forest Reserves, Tanzania

The study was conducted between 1998 and 2000 to compare the number, types and consumption of indigenous fruit species by sex and age classes in the Uluguru North Forest Reserve (UNFR) and Ruvu North Forest Reserve (RNFR). Data were collected through household interviews and forest inventory. A total of 120 households from six villages (3 bordering the RNFR and 3 near the RNFR) were randomly selected for interviews. Plots with the size of 0.1 ha were established along the transects after every 400m during forest inventory for the purpose of identifying fruit plants. A total of 25 indigenous fruit species were identified in the study areas. 20 and 16 species were identified in the UNFR and the RNFR respectively. 9 species were only found in UNFR while 5 were identified in RNFR. 11 species were identified in both study areas. Responses on consumption by age showed that, in both sites, children consumed more indigenous fruits than any other age group followed by adult women. The consumption of these fruits in UNFR was 64% (children), 47% (adult women) and 25% (adult men) while in RNFR consumption was 46% (children), 39% (adult women) and 23% (adult men). Seasonality and availability of exotic species had effect on consumption of indigenous fruits. The consumption of indigenous fruits appeared to be much higher when the supply of exotic fruits was low and vice versa. TJFNC Vol. 75 2004: pp. 65-7

Household Tree Planting In Kilosa District, Tanzania

The objective of this study was to assess household tree planting efforts and to investigate current constraints to afforestation in Kilosa District, Tanzania. The results of the study showed that 77 % of farmers in the district have planted trees in their farms, whether by themselves or previous farm owners. The average total number of planted trees was estimated to be 40 + 7 (SE) trees per household. Men headed household tended to have more planted trees [44 + 9 (SE)] than female headed households [31 + 11 (SE)]. Middle age households had planted more trees [49 + 14 (SE)] than younger [29 + 13 (SE)] and elder households [33 + 8 (SE)]. Tree planting appeared to be positively influenced by farm size and education. Fruit trees dominated in the home gardens (53 %) while non-fruits trees were more abundant far away from homestead. An investigation of constraints to tree planting and tending revealed that lack of seedlings (32 % of respondents), shortage of designated planting sites (24 %) and uncertainty over land ownership appeared to be the most important obstacles to tree planting in the district. It was surprising that land shortage became as the second leading constraint to tree planting despite the apparent low density of human population (32 people per km2 in 2000). The study concludes by recommending that in order to promote tree planting in the country\'s rural areas, farmers have to be assisted in production of seedlings. Other necessary prerequisites are effective land-use planning and clear secured tenure over land. TJFNC Vol. 75 2004: pp. 99-10

The Chronic Diseases Clinic of Ifakara (CDCI)- establishing a model clinic for chronic care delivery in rural sub-Saharan Africa

The rollout of antiretroviral drugs in sub-Saharan Africa to address the huge health impact of the HIV pandemic has been one of the largest projects undertaken in medical history and is an unprecedented medical success story. However, the path has been and still is characterized by many far reaching implementational challenges. Here, we report on the building and maintaining of a role model clinic in Ifakara, rural Southwestern Tanzania, within a collaborative project to support HIV services within the national program, training for staff and integrated research to better understand local needs and improve patients' outcomes

Measuring the capability to raise revenue process and output dimensions and their application to the Zambia revenue authority

The worldwide diffusion of the good governance agenda and new public management has triggered a renewed focus on state capability and, more specifically, on the capability to raise revenue in developing countries. However, the analytical tools for a comprehensive understanding of the capability to raise revenue remain underdeveloped. This article aims at filling this gap and presents a model consisting of the three process dimensions ‘information collection and processing’, ‘merit orientation’ and ‘administrative accountability’. ‘Revenue performance’ constitutes the fourth capability dimension which assesses tax administration’s output. This model is applied to the case of the Zambia Revenue Authority. The dimensions prove to be valuable not only for assessing the how much but also the how of collecting taxes. They can be a useful tool for future comparative analyses of tax administrations’ capabilities in developing countries.Die weltweite Verbreitung der Good-Governance- und New-Public-Management-Konzepte hat zu einer zunehmenden Konzentration auf staatliche Leistungsfähigkeit und, im Besonderen, auf die Leistungsfähigkeit der Steuererhebung in Entwicklungsländern geführt. Allerdings bleiben die analytischen Werkzeuge für ein umfassendes Verständnis von Leistungsfähigkeit unterentwickelt. Dieser Artikel stellt hierfür ein Modell vor, das die drei Prozess-Dimensionen „Sammeln und Verarbeiten von Informationen“, „Leistungsorientierung der Mitarbeiter“ und „Verantwortlichkeit der Verwaltung“ beinhaltet. „Einnahmeperformanz“ ist die vierte Dimension und erfasst den Output der Steuerverwaltung. Das mehrdimensionale Modell wird für die Analyse der Leistungsfähigkeit der Steuerbehörde Zambias (Zambia Revenue Authority) genutzt. Es erweist sich nicht nur für die Untersuchung des Wieviel, sondern auch des Wie des Erhebens von Steuern als wertvoll. Die vier Dimensionen können in Zukunft zur umfassenden und vergleichenden Analyse der Leistungsfähigkeit verschiedener Steuerverwaltungen in Entwicklungsländern genutzt werden

Impacts of savanna trees on forage quality for a large African herbivore

Recently, cover of large trees in African savannas has rapidly declined due to elephant pressure, frequent fires and charcoal production. The reduction in large trees could have consequences for large herbivores through a change in forage quality. In Tarangire National Park, in Northern Tanzania, we studied the impact of large savanna trees on forage quality for wildebeest by collecting samples of dominant grass species in open grassland and under and around large Acacia tortilis trees. Grasses growing under trees had a much higher forage quality than grasses from the open field indicated by a more favourable leaf/stem ratio and higher protein and lower fibre concentrations. Analysing the grass leaf data with a linear programming model indicated that large savanna trees could be essential for the survival of wildebeest, the dominant herbivore in Tarangire. Due to the high fibre content and low nutrient and protein concentrations of grasses from the open field, maximum fibre intake is reached before nutrient requirements are satisfied. All requirements can only be satisfied by combining forage from open grassland with either forage from under or around tree canopies. Forage quality was also higher around dead trees than in the open field. So forage quality does not reduce immediately after trees die which explains why negative effects of reduced tree numbers probably go initially unnoticed. In conclusion our results suggest that continued destruction of large trees could affect future numbers of large herbivores in African savannas and better protection of large trees is probably necessary to sustain high animal densities in these ecosystems

Environmental conservation and social benefits of charcoal production in Mozambique

Charcoal is an important source of energy and income for millions of people in Africa. Its production often drives forest degradation and deforestation which have impacts on the local people that remain poorly understood. We present a novel methodology for analysing the contribution of woodland ecosystem services (ES) to rural well-being and poverty alleviation, which takes into account access mechanisms to ES, trade-offs between ES, and human response options. Using a participatory approach, a set of land use change scenarios were translated into a probabilistic model that integrates biophysical and social data. Our findings suggest that in highly forested areas woodland degradation does not have a critical impact on the local use of the three ES studied: charcoal, firewood and grass. Social factors show the largest impact on the quantity of charcoal produced, e.g. female-headed households experience the greatest barriers to access charcoal production. Participating in forest associations and diversifying income activities lead to greater charcoal production. Results show that charcoal production increases some aspects of well-being (e.g. household assets), but does not decrease acute multidimensional poverty. Great efforts are required to reach a charcoal production system that alleviates poverty, improves environmental sustainability, and provides a reliable charcoal supply.info:eu-repo/semantics/publishedVersio

Differential utilization and Ethnobotany of trees in Kitulanghalo forest reserve and surrounding communal lands, eastern Tanzania

Economic Botany, 2000; 54(3):328-343 .This study documents the utilization aspects and distri- bution of ethnobotanical knowledge of the local people of Morogoro, Tanzania, as a first step towards sustainable utilization and conservation of tropical woodlands. A total of 133 arbo- rescent species in 31 families was identified of which 69% had a variety of uses. These uses were classified into 12 categories and major uses were charcoal, firewood, medicine, and poles. Most tree species have occasional uses, but a few are exceptionally useful and thus their levels of utilization may far exceed their regeneration and production. The questionnaire survey in- dicated that 62% of the respondents agreed that traditional medical services were more avail- able than modem services. Utilization surveys indicated that wooden poles are the building material used in 98% of the dwellings and storage structures, wild foods were useful for food security especially during drought years, and high quality timber trees have been depleted in the forest because of earlier exploitation by pit-sawing. The distribution of ethnobotanical knowledge indicated that much of the relevant ethnobotanical and utilization information was held by more aged members of the society and hence there is a clear need to capture this knowledge before it is lost. This study has shown that resources are defined by use and culture, and some components of ethnobotanical knowledge have potential for the sustainable manage- ment of miombo woodlands
