    Carbon storage potential of grassland ecosystems in the eastern arc mountains: a case study of Udzungwa mountains, Tanzania
    (Sokoine University of Agriculture, 2011) LASWAI,FRANCIS FAUSTINE
    Grasslands are believed to store carbon in below and above ground. However, little is known on the actual proportion amount of carbon stored in the different carbon pools in the grassland ecosystems. This study aimed at quantifying below and above ground carbon stocks of floodplain and upland grasslands. Quadrants measuring I m 2 were established systematically along transects in the floodplain and upland grasslands. Above ground vegetation and litter were sampled in I m x I m plots and below ground roots and soils were sampled in pits of 0.5 m x 0.5 m x 0.6 m. Soil samples were taken from 0-15 cm, 15-30 cm, 30 - 45 cm and 45 - 60 cm depth. Carbon in shoots, litter and roots was determined by Loss on Ignition method. Carbon in soils was determined by Walkley Black method. Data were analyzed using descriptive statistics and ANOVA. The above ground carbon in upland grassland was 12.60 ± 0.50 t ha'1 and 3.09 ±0.11 t ha'1 for vegetation and litter respectively. Below ground carbon was 7.82 ± 0.57 t ha'1 for roots and 40.26 ± 1.17 t ha'1 for soils. In the floodplain grasslands above ground carbon was 33.04 ± 1.18 t ha'1 for^vegetation and 1.89 ± 0.08 t ha'1 for litter. On the other hand below ground carbon was 6.22 ± 0.25 t ha'1 and 24.63 ± 0.88 t ha'1 for roots and soil respectively. In total upland grasslands has potential to store 63.77 ± 2.35 t ha'1 of carbon while the floodplain grasslands storage was 65.78 ± 2.39 t C ha'1. With exception of roots all other pools showed a significant difference in carbon storage between floodplain and upland grasslands (P = 0.000). Both upland and floodplain grasslands have high potential for carbon storage and emission mitigation.

    Consumers’ preference on imported and locally made furniture in Dar es Salaam and Arusha, Tanzania
    (SAGE, 2018) Kumburu, Neema P.; Kessy, John Francis
    This study was designed to assess the consumer’s preference between imported and locally made furniture in Dar es Salaam and Arusha in Tanzania. Primary and secondary data for the study were collected from furniture consumers in the study area. A total of 134 consumers were surveyed. Questionnaires and documentary reviews were used for data collection. Descriptive statistics and binary logistic regression were used in the analysis of data. The result of the study revealed significant differences on the levels of consumers’ preference for furniture products. Imported furniture seems to be far preferred by consumers. It was observed that the major differences in consumers’ preference for furniture were due to quality and design. This study provides valuable implications for local small- scale manufacturers if they want to compete in the globalized market. It is, therefore, recommended that local furniture manufacturers should acquire adequate skills, technology and innovation in order to produce competitive products.

    The role of non wood forest products in improving livelihoods of communities surrounding Jozani and Chwaka Bay national park, Zanzibar.
    (Sokoine University Of Agriculture., 2010) Mkarafuu, Nassor Said
    The role of Non Wood Forest Products (NWFPS) In the communities This study was conducted to asses the role of Non Wood Forest Products (NWFPs) in improving livelihoods of the communities surrounding Jozani and Chwaka Bay National Park in Zanzibar. The study aimed to document, asses the status and contribution of NWFPs, identify roles of user groups and constraints towards development of NWFPs in the study area. Six villages were selected based on accessibility to the forests and availability of NWFPs. Study was conducted in two phases: Phase one involved preliminary surveys and Participatory Rural Appraisals. Phase two was questionnaire surveys with households, key informants and field inventory. Data on PRA were analyzed with the help of local communities, while Statistical Package for Social Science (SPSS) was used for questionnaires. Revenue accrued from different sources was computed in MS Excel. A total of 88 and 26 NWFPs plant and animal species respectively were recorded. NWFPs contribute 27 % of household’s food security, 32 % of income generation while 97 % of households rely for primary health care. The study revealed some constraints towards development of NWFPs. It is concluded that NWFPs contribute in improving livelihood of communities for subsistence, primary health care and income. The study also noted a decrease in NWFPs. It is concluded that gender roles has influence in collection, processing and marketing of NWFPs. It is recommended that information and training on NWFPs should be provided to the communities. Also utilization plan of NWFPs should be developed and collaboration between government and communities is needed to improve protection of the resoures.
