A ciência tem mostrado nas últimas décadas que a conta- minação por mercúrio (Hg) é um problema ambiental e de saúde pública. Uma importante fonte poluidora é o garim- po ilegal de ouro, que vem crescendo vertiginosamente, deixando um rastro de destruição. Outras atividades rea- lizadas por seres humanos, incluindo o desmatamento, a queimada de florestas e a construção de hidrelétricas, au- mentam os níveis de contaminação por mercúrio em cor- pos d’agua e no ambiente.

Urban planners are entrusted with the power to make critically important, long-term decisions that determine the future development of cities and towns around the world. The decisions they take shape the urban environment and directly affect the lives and livelihoods of entire communities.

Informal Land Subdivisions And Their Effects On Spatial Development In Peri Urban Areas:The Case Of Kichangani Suward In Kigamboni Municipality, Dar Es Salaam, Tanzania

Context and Background: Land is an important resource for human survival as well as that of other living organisms. Despite its importance, there are many problems that come with its management. There are increasing controversies and disputes over the ownership, access, and use of land. This is due to the increase in land demand, owing to factors such as population growth, urbanization, and food security. Land disputes in the Ashanti Region have drastically escalated recently as a result of these factors.

Context and background               Residing in areas of flood risk informal settlements is more or less normal among low-income households in most cities of the developing countries. While living in such settlements present challenge to quality of life, many among the urban poor offer these areas.Goal and objectives:This paper analyses factors that drive urban residents to acquire land and build houses in flood prone areas.

Context and backgroundExtreme heat is one of the challenges facing urban areas. Though this constitutes a global urban challenge, especially large cities in the world, Urban studies have barely paid attention to urban heat.Goal and Objectives:This study attempts to respond to the research gap through drawing on early warning systems to explore community and governments to extreme heat, in particular, how residents adapt to extreme heat in Dar es Salaam.Methodology:Kigogo ward in the city of Dar es Salaam was selected as a case study area.

In Tanzania, the increase in the number of commercial motorcycles operating in the urban areas has resulted to the establishment of informal parking spaces in various parts of towns and cities. This research aimed to explore the criteria used by commercial motorcycle operators to establish informal motorcycle parking spaces in urban areas. The study on the influence of land use on the spatial distribution of informal motorcycle parking spaces applied triangulation techniques to ensure the validity and reliability of the collected data.

Context and background: Cities in developing world are experiencing rapid urbanization characterized by rapid population growth. Tanzania like many other most of urban areas face poor public transport which force city dwellers to use alternative transport including walking.

Smart Cities In Mauritius: Opportunities And Challenges

Nexus SAMs aims to improve the quality and standardize the construction process of SAMs using a standard toolkit that enables tracing data sources and assumptions. The unified structure of nexus SAMs allows for more robust cross-country comparisons of economies, especially the sectoral composition, allocation of government spending and trade orientation.

The Ethiopian economy relies predominantly on rainfed agriculture for income generation, export earnings, and rural livelihoods. However, the frequency and intensity of extreme ago-climatic events projected by climate scenarios suggest considerable and growing risks from climate change to the country’s agri-food systems and the overall economy. This study assesses the economic impacts of recurrent climate shocks on the Ethiopian economy to 2040.

The review attempted to evaluate the quality attributes and the preferred selected roots, tubers, and bananas (RTB) items (gari/eba, lafun, yam flour, pounded yam, boiled yam, and plantain flour) among the end-users in Nigeria’s rural, peri-urban, and urban segments. The results showed that depending on location, consumers’ preferred quality attributes of gari in the rural area are dry, bright/shiny, white, sweet, dense, fine, cooked aroma and sour/sweet gari.
