It is mostly noted that the design for residential purpose is professionally considered universal, distinct and specific. The socio-economic, cultural and traditional aspects which affect the house users’ requirements and hence the residential designs seem to be considered by professionals’ standpoint as a mere user’s ignorance and lack of access to suitable designs. In this respect, the attributes of vernacular and traditional architecture are sought to unpack the intrinsic relevance to contemporary architecture of residential design within the local context. The case study has been conducted in Dar es Salaam city assessing the local residential house owners’ requirements aiming to understand the social, economic and cultural factors which impact the architecture of residential designs. The findings show that residential designs and use are dynamic and likely to transform based on the owners’ evolving socio-cultural, economic and spatial requirements which highlight the relevance of vernacular and traditional architecture. This trend raises the professional concern on the need for further interrogation of current residential architecture approach. Thus, it has been concluded that professionals perspective should opt for less control of residential requirements and emphasise the recognition of socio-economic and cultural aspects which aspire for flexibility of form, function and spatial organization and facilitate design control by the house owner. Such revelation indicate the validity of vernacular and traditional architectural approach which integrate the local knowledge, optimum utilization of resources, nature and built environment.

This study investigated the levels of pesticides and metabolites in vegetables from major markets in Dar es Salaam city, Tanzania. Samples of fresh cabbage, spinach, and onions from the markets were analysed for pesticide residues. Extraction was performed using acetone followed by dichloromethane : cyclohexane mixture and the extracts were cleaned up using Florisil. The compounds were determined by gas chromatography-mass spectrometry (GC-MS). Pesticides and metabolites were detected in 72.2% of the samples. The detected pesticide residues and their highest mean concentrations were p,p′-DDT 4.00 × 10−3 mg/kg, p,p′-DDD 6.40 × 10−1 mg/kg, o,p′-DDD 1.00 × 10−2 mg/kg, α-endosulfan 6.00 × 10−1 mg/kg, β-endosulfan 2.10 × 10−1 mg/kg, chlorpyrifos 3.00 mg/kg, and cypermethrin 4.00 × 10−2 mg/kg. The most frequently detected compounds were p,p′-DDD and chlorpyrifos. The order of contamination was spinach > cabbage > onions. Generally, there were no significant variations in concentrations of pesticide residues among samples and sampling sites, which indicated similarities in contamination patterns. The concentrations of contaminants were above the maximum residue limits (MRLs) in 33.3–50% of the samples. The findings indicated risks and concerns for public health.

Green spaces in urban areas including in Dar es Salaam City provide multiple ecological, social and economic benefits. Despite their benefits they are inadequately documented in terms types, coverage and uses. This paper attempts to provide information on types, coverage and uses of green space in Dar es Salaam City. A number of methods including literature review, interpretation of remotely sensed image, interviews, focus group discussions and questionnaires were used to document city greenery. The research findings show that residential greenery is made up of greenery found within and external to plots. The dominant green spaces external to residential plots were natural and semi natural vegetation while within plots were woody plants, plots farms vegetable and ornamental gardens. Distribution of greenery varied among the wards due to differences in building density and distance from the city centre. Natural and semi natural vegetation increased with decrease of building density and increase of distance from the city centre, while the number of plots with trees for shade increased with increase of building density. Only Kawe ward that had greenery above Tanzania space planning standards, the other three wards which are informal settlements had green space deficit. Three quarters of the households use green spaces for shade provision and cooling, two thirds as a source of food products and a quarter for recreation and aesthetic purposes. The study reveals that Dar es Salaam City residents invest predominantly on shade trees in their residential plots compared to other green space types.

<p align="center"><strong><em>ABSTRACT</em></strong></p><p><em>Nowadays, the development of f</em><em>isheries strategic issues </em><em>is related to </em><em>poverty and welfare of fishermen. In 2010 - 2014, Ministry of Marine and Fisheries implemented Business Development Program of Rural Area by creating a Joint Business Group (</em><em>J</em><em>B</em><em>G</em><em>) to help traditional and small scale fishermen who categorized as poor. This study aimed to determine the performance of JBG of gillnet fishermen and to identify the attributes of performance (aspects of institutional, socio-cultural, economic, environmental and policy) in Barsela Aceh. Data was collected by purposive sampling method from 13 JBG of gillnet fishermen. IPA analysis and gap analysis were performed to measure each attribute and attribute's performance. The results showed that the value of the gap in the aspect of the institution of 1.87, and socio-cultural aspect of 1.91, which are categorized as good enough. Furthermore, the value of the economic aspect (2,12), environmental aspect (2,43) and policy aspect (2.21) are categorized as less good</em><em>. </em><em>The attributes which categorized as </em><em>a top priority</em><em> (in quadrant A) are the aspect of institution, namely; human resources quality of JBG, the level of utilization of information technology and marketing, participation in training event, frequency of training held by related agencies and traditional institutions and the effectiveness of PPTK. Socio-cultural aspects are the desire to be independent culture, work ethic culture, group cohesiveness, and JBG assets are jointly managed. In economic aspect are active savings and loan activities, the level of turnover development of JBG and the level of market opportunities for JBG fishermen's business. Environmental aspects are the effectiveness of target fish species catch, high economic value of fish and environment-friendly technologies. Policy aspects are sanctioned policies for fictitious JBG, policies about who can become a member of JBG, policy management in preparing a joint business plan and sanctions for members who violate the rules.</em><em></em></p><p class="TubuhTulisanAll"><strong><em>Keywords:</em></strong><strong><em> </em></strong><em>Barsela Aceh, </em><em>JBG</em><em>, gillnet</em><em> fishermen</em><em></em></p><p align="center"><strong>ABSTRAK</strong></p><p class="Abstrakisi">Perkembangan isu strategis perikanan saat ini adalah kemiskinan dan kesejahteraan nelayan.

Abstract Cimex hemipterus resistance to residual insecticides is a growing public health concern worldwide. Herein, we report the susceptibility status of C. hemipterus against pyrethroid (permethrin) and organophosphate (dichlorvos) insecticides in Dar es Salaam. The knockdown efficacy of dichlorvos (99%) was greater than that of permethrin (43%), and mortality at the end of 24 h was also greater for dichlorvos than for permethrin. Mortality in recommended concentration of permethrin was lower than manufacturer’s expectations. In contrast, similar concentrations in dichlorvos resulted into mortality of 100% at the end of 24 h. LC50 and LC95 values for permethrin were 3.36 (2.356–4.364) and 2,887.39 (2,886.37–2,888.39), respectively, whereas those of dichlorvos were 7.91 (3.85–11.97) and 44.39 (40.33–48.45). Dar es Salaam city has high coverage and usage of long-lasting insecticidal nets (LLINs) for prevent malaria. The resistance in bedbugs to permethrin may be related to the widespread use of the insecticide in LLINs. We recommend of the change from pyrethroids dichlorvos for the control of bedbugs.
