Academic literature on the topic 'Land use, Urban – Mozambique – Maputo'

Landfill site selection is problematic in many countries, especially developing nations where there is rapid population growth, which leads to high levels of inadequate waste disposal. To find sustainable landfill sites in sprawling cities, this study presents an approach that combines geographic information system (GIS) with multi-criteria (social, environmental and, technical criteria) and the population growth projection. The greater Maputo area in Mozambique was selected as a representative city for the study, which is undergoing rapid urbanization. Six criteria, i.e., land use, transport networks, hydrology, conservation reserve, geology and slope, were considered and overlaid in the GIS using an analytic hierarchy process (AHP). The arithmetic projection of the population trend suggests that the greater Maputo area is experiencing a rapid and uncontrolled population growth, especially in Matola city. These pronounced changes in population then significantly change the landfill placement decision making. Dynamic and static scenarios were created, based on the analysis of multi-criteria and the areas likely to undergo future increased population growth. A comparative evaluation in a scenario of dynamic behavior considering future population showed that suitable areas for landfill sites have been drastically modified due to social and environmental factors affected by population distribution in some regions. The results indicate that some suitable areas can generate land use conflicts due to population growth with unplanned land use expansion. Finally, the western part of Matola city is recognized as the most recommendable landfill site, which can serve both Maputo and Matola city with affordable costs. This study provides an effective landfill placement decision making approach, which is possible to be applied anywhere, especially in developing countries to improve sustainable municipal solid waste management systems.

ObjectivesThe study aimed at identifying the commonly used non-prescribed antibiotics (NPAs) and the main health conditions leading to the practices of self-medication with antibiotics (SMAs) in Maputo city, Mozambique.DesignCross-sectional qualitative study based on individual and group interviews.SettingThe study was conducted in nine pharmacies of three socioeconomic areas of Maputo city, from October 2018 to March 2019.ParticipantsThe study included 32 pharmacy clients and 17 pharmacists. The pharmacy clients included men 10 (31%) and women 22 (69%) ranging from 19 to 67 years while the pharmacists included men 6 (35,3%) and women 11 (64,7%) with ages ranging from 24 to 47 years.FindingsThe majority of the pharmacy clients 30 (93.75%) admitted frequent use of NPAs, 15 (88.2%) out of the 17 pharmacists admitted dispensing NPAs. While the majority of the participants (16) mentioned the use of amoxicillin, also known as ‘two colours medicine’, 14 mentioned the use of cotrimoxazole and seven mentioned amoxicillin with clavulanic acid. Two to five participants also used tetracycline, ciprofloxacin, azithromycin, doxycycline, erythromycin, metronidazole and phenoxymethylpenicillin. The above mentioned NPAs were used to treat self-perceived sore throat, fever, pain, cough, vaginal discharge, eye problems, the common influenza, urinary infections, respiratory tract infections, wounds and toothaches.ConclusionsAntibiotics are perceived as essential medical resources to manage health and illnesses. While taking an active role in their health-disease process, participants commonly used amoxicillin, ‘two colours’, cotrimoxazole and amoxicillin with clavulanic acid to manage their health and that of their families. In this sense, the practices of SMAs were perceived as part of the self-care process and not necessarily as misuse of antibiotics. A wideunderstanding of health-seeking beliefs and behaviours regarding the utilisation of antibiotics is needed to inform public health experts, health policymakers and other stake-holders in designing and implementing public health education and health promotion programsat all levels in Mozambique.

Data from three separate studies conducted in Maputo, Mozambique, in 1993 are used to analyse the relationship between the type of social environment in which women work and their fertility and contraceptive use. The analysis finds that women who work in more collectivized environments have fewer children and are more likely to use modern contraception than women who work in more individualized milieus and those who do not work outside the home. Most of these differences persist in multivariate tests. It is argued that collectivized work environments are most conducive to diffusion and legitimation of reproductive innovations. In contrast, individualized environments tend to isolate women and therefore may retard their acceptance of innovative fertility-related behaviour.

Studies on sexual behaviour within the area of HIV prevention in sub-Saharan Africa have largely focussed on unsafe sex and obstacles to condom use rather than examined factors potentially favouring safe sex. The present study examines how class, gender and peer education affects safe sex in male youth and identifies the reasons behind condom use by combining a questionnaire survey with ethnographic fieldwork. Findings from the field study among male secondary school youth in Maputo, Mozambique point to middle class youth from urban schools as more likely to use condoms than working class youth from suburban schools. Examining the meanings behind use or non-use of condoms the study identified narratives in middle class youth favouring safe sex in response to better social conditions, career opportunities and ‘modern’ masculinities, whereas working class youth explained non-use of condoms as due to lack of hope and job opportunities and by reference to fatalist ideas that life is out of their hands and that it’s better to ‘live in the moment’.

Shared sanitation—sanitation facilities shared by multiple households—is increasingly common in rapidly growing urban areas in low-income countries. However, shared sanitation facilities are often poorly maintained, dissuading regular use and potentially increasing disease risk. In a series of focus group discussions and in-depth interviews, we explored the determinants of shared sanitation management within the context of a larger-scale health impact evaluation of an improved, shared sanitation facility in Maputo, Mozambique. We identified a range of formal management practices users developed to maintain shared sanitation facilities, and found that management strategies were associated with perceived latrine quality. However—even within an intervention context—many users reported that there was no formal system for management of sanitation facilities at the compound level. Social capital played a critical role in the success of both formal and informal management strategies, and low social capital was associated with collective action failure. Shared sanitation facilities should consider ways to support social capital within target communities and identify simple, replicable behavior change models that are not dependent on complex social processes.

Due to its location, Mozambique suffers from cyclical flooding associated with heavy rains and cyclones. In recent years, extreme flood events affected millions of people, disrupting the economic recovery process that followed the peace agreement in 1992. Despite this natural threat, most of the population continues to live in flood prone areas both in rural environment, due to the dependency on agricultural activities, and in urban environment, since unsafe zones are often the only affordable option for new settlers. This paper presents a brief analytical review on different issues related with urban informal settlements, or slums, based on different project activities developed by the United Nations Human Settlements Programme (UN-HABITAT) in Mozambique. The aim is to identify applicable strategies to reduce vulnerability in urban slums, where approximately 70 percent of the urban population live. The implemented project activities target different organisational levels in an integrated manner, seeking for active involvement of the Government, local authorities and communities at each implementation stage, from decision-making to practical implementation. They consist of three main components: 1) supporting policy-making in order to ensure sustainable urban development, 2) delivering a comprehensive training and capacity building based on the mainstreaming concept of “Learning How to Live with Floods” as valid alternative to resettlement, and 3) facilitating participatory land use planning coupled with physical upgrading interventions at the local level. In the long-term, the intention of UN-HABITAT is to progressively focus on community-based slum upgrading and vulnerability reduction activities, coordinated by local authorities and actively monitored by central institutions, in improving and managing basic services and infrastructures (i.e. water supply, drainage, sanitation, waste management, road network, etc). This type of bottom-up experiences should then represent a basis for setting up a slum upgrading intervention strategy to be applied at the national level.

District of Namaacha in Maputo Province of Mozambique presents a high wind potential, with an average wind speed of around 7.5 m/s and huge open fields that are favourable to the installation of wind farms. However, in order to make better use of the wind potential, it is necessary to evaluate the operating conditions of the turbines and guide the independent power producers (IPPs) on how to efficiently use wind power. The investigation of the wind farm operating conditions is justified by the fact that the implementation of wind power systems is quite expensive, and therefore, it is imperative to find alternatives to reduce power losses and improve energy production. Taking into account the power needs in Mozambique, this project applied hybrid optimisation of multiple energy resources (HOMER) to size the capacity of the wind farm and the number of turbines that guarantee an adequate supply of power. Moreover, considering the topographic conditions of the site and the operational parameters of the turbines, the system advisor model (SAM) was applied to evaluate the performance of the Vestas V82-1.65 horizontal axis turbines and the system’s power output as a result of the wake effect. For any wind farm, it is evident that wind turbines’ wake effects significantly reduce the performance of wind farms. The paper seeks to design and examine the proper layout for practical placements of wind generators. Firstly, a survey on the Namaacha’s electricity demand was carried out in order to obtain the district’s daily load profile required to size the wind farm’s capacity. Secondly, with the previous knowledge that the operation of wind farms is affected by wake losses, different wake effect models applied by SAM were examined and the Eddy–Viscosity model was selected to perform the analysis. Three distinct layouts result from SAM optimisation, and the best one is recommended for wind turbines installation for maximising wind to energy generation. Although it is understood that the wake effect occurs on any wind farm, it is observed that wake losses can be minimised through the proper design of the wind generators’ placement layout. Therefore, any wind farm project should, from its layout, examine the optimal wind farm arrangement, which will depend on the wind speed, wind direction, turbine hub height, and other topographical characteristics of the area. In that context, considering the topographic and climate features of Mozambique, the study brings novelty in the way wind farms should be placed in the district and wake losses minimised. The study is based on a real assumption that the project can be implemented in the district, and thus, considering the wind farm’s capacity, the district’s energy needs could be met. The optimal transversal and longitudinal distances between turbines recommended are 8Do and 10Do, respectively, arranged according to layout 1, with wake losses of about 1.7%, land utilisation of about 6.46 Km2, and power output estimated at 71.844 GWh per year.

Abstract. The water–energy–food (WEF) nexus has been promoted in recent years as an intersectional concept designed to improve planning and regulatory decision-making across the three sectors. The production and consumption of water, energy and food resources are inextricably linked across multiple spatial scales (from the global to the local), but a common feature is competition for land which through different land management practices mediates provisioning ecosystem services. The nexus perspective seeks to understand the interlinkages and use systems-based thinking to frame management options for the present and the future. It aims to highlight advantage and minimise damaging and unsustainable outcomes through informed decisions regarding trade-offs inclusive of economic, ecological and equity considerations. Operationalizing the WEF approach is difficult because of the lack of complete data, knowledge and observability – and the nature of the challenge also depends on the scale of the investigation. Transboundary river basins are particularly challenging because whilst the basin unit defines the hydrological system this is not necessarily coincident with flows of food and energy. There are multiple national jurisdictions and geopolitical relations to consider. Land use changes have a profound influence on hydrological, agricultural, energy provisioning and regulating ecosystem services. Future policy decisions in the water, energy and food sectors could have profound effects, with different demands for land and water resources, intensifying competition for these resources in the future. In this study, we used Google Earth Engine (GEE) to analyse the land cover changes in the Zambezi river basin (1.4 million km2) from 1992 to 2015 using the European Space Agency annual global land cover dataset. Early results indicate transformative processes are underway with significant shifts from tree cover to cropland, with a 4.6 % loss in tree cover and a 16 % gain in cropland during the study period. The changes were found to be occurring mainly in the eastern (Malawi and Mozambique) and southern (Zimbabwe and southern Zambia) parts of the basin. The area under urban land uses was found to have more than doubled during the study period gearing urban centres increasingly as the foci for resource consumption. These preliminary findings are the first step in understanding the spatial and temporal interlinkages of water, energy and food by providing reliable and consistent evidence spanning the local, regional, national and whole transboundary basin scale.

African woodlands form a major part of the tropical grassy biome and support the livelihoods of millions of rural and urban people. Charcoal production in particular is a major economic activity, but its impact on other ecosystem services is little studied. To address this, our study collected biophysical and social datasets, which were combined in ecological production functions, to assess ecosystem service provision and its change under different charcoal production scenarios in Gaza Province, southern Mozambique. We found that villages with longer histories of charcoal production had experienced declines in wood suitable for charcoal, firewood and construction, and tended to have lower perceived availabilities of these services. Scenarios of future charcoal impacts indicated that firewood and woody construction services were likely to trade-off with charcoal production. However, even under the most extreme charcoal scenario, these services were not completely lost. Other provisioning services, such as wild food, medicinal plants and grass, were largely unaffected by charcoal production. To reduce the future impacts of charcoal production, producers must avoid increased intensification of charcoal extraction by avoiding the expansion of species and sizes of trees used for charcoal production. This is a major challenge to land managers and policymakers in the area. This article is part of the themed issue ‘Tropical grassy biomes: linking ecology, human use and conservation’.

Maputo City has a very high population density and sources of domestic energy such as electricity, gas or even kerosene are not yet available for the majority of the population. Demand for wood products is high both in the rural and urban areas for consumption and generation of income. Coupled with agricultural expansion, this raises concerns over the sustainability of use of natural forest resources. Nevertheless, the government has limited financial and human resources to establish plantations which can satisfy the increases in wood demand, especially in the urban areas. The 1991 Reforestation policy attempted to overcome this by adopting as strategy the involvement of the users, especially the rural community, in the replacement of exploited forest resources. However, reported failure in implementation of this strategy has suggested that there is need to elaborate a decision support tool, which would encapsulate the multidisciplinary nature of the problem, at both farm and regional levels. The underlying hypothesis of this research is, therefore, that despite data scarcity and/or unreliability, it is possible to develop a planning framework applying a relatively sophisticated planning tool such as Mathematical Programming. The aim of the thesis is to perform an <I>ex-ante</I> analysis of the impact of the strategy, stressing a bottom-up and integrated planning procedure and including decision makers at the two levels. Both single and multiobjective mathematical programming methods are applied, preceded by the use of Geographical Information Systems in the analysis of the spatial distribution of resources. The results show that by integrating agriculture, forestry and animal husbandry activities and constraints in the farm planning framework, it is possible to assess the individual potential responses to reforestation alternatives. Furthermore, conflicts among national goals are assessed using aggregation techniques. This provides policy makers with information on the opportunity cost that may be associated with changes in government priorities.

Esta região é reconhecida pelas autoridades administrativas nacionais e provinciais como estando sob pressão de uso agropecuário, desmatamento devido à exploração desenfreada das florestas, queimadas, pecuária extensiva de bovinos e caprinos. Estes fatos estão trazendo e acentuando problemas sócio-ambientais, nomeadamente, insegurança alimentar, baixa produtividade das culturas, erosão e assoreamento dos cursos de água. A avaliação e determinação da capacidade do uso das terras numa bacia hidrográfica são de vital importância para o planejamento e uso racional do solo e outros recursos da terra, dado que o uso inadequado e sem observância da sua capacidade do suporte tem provocado sua degradação. A partir de avaliações dos elementos do meio físico e das atividades desenvolvidas na região compreendidas entre as bacias de Chanagalane e Mazimunhama, com destaque para as de agropecuárias, fez-se uma avaliação das terras, pelo sistema de capacidade de uso, conjugado com as classes de manejo do sistema de aptidão agrícola das terras, a fim de atender ao planejamento e conservação dos recursos da terra e minimizar os problemas ambientais decorrentes do seu uso inadequado. Os dados foram gerados e integrados no SIG Arcinfo/Arcgis 9.2. Os planos de informação para entrada e cruzamento no SIG foram a carta de solos, cartas topográficas (Classes de declives) e uso das terras. Este último componente foi obtido por processamento digital de imagens ASTER. As análises permitiram concluir que a unidades de solos Bv (Basaltos vermelhos) de textura francoargilo- arenoso que ocorrem em declive plano (0-3%) cobrem a maior parte área de estudo com 172.8 km2 (30.1%); este solo foi avaliado como classe IIIs-p/f no sistema de capacidade de uso e 2ab(c) no sistema de avaliação para a aptidão agrícola, mostrando que é um solo adequado para o cultivo de culturas anuais e até perenes, porém têm problemas ligados a profundidade efetiva dos solos e à baixa fertilidade. Por causa da limitante profundidade não é recomendável o uso de mecanização pesada. A segunda unidade de solos que ocupa uma área considerável da área em estudo é a dos solos coluvionares (C) com 154.9 Km2 (26.9%) que ocorrem em relevo suave ondulado a ondulado e estão inclusos na subclasse IVs-sl/so. Estes solos são limitados pela salinidade e sodicidade e risco de inundação.<br>Abstract: The study area consists of the sub-basins of the Changalane and Mazimunhama rivers, tributaries of the Tembe river, situated in the Maputo province of Southern Mozambique. The region is recognized by the national and provincial authorities as being under pressure from: agricultural use, deforestation due to uncontrolled exploitation of forests, forest fires and the farming of cattle and goats. These factors are creating and exacerbating social and environmental problems, in particular: food insecurity, low crop yields, erosion and siltation of water courses. The evaluation and determination of land use capacity in a hydrographic basin is of vital importance to the planning and rational use of soil and other terrestrial resources given that misuse and disregard of this capacity lead to degradation. From an evaluation of the physical environment and the activities undertaken in the Chanagalane and Mazimunhama basin regions, especially those concerning argiculture, an assessment was made of the land use capability by combining the concepts of system management and agricultural fitness. The purpose of this evaluation was to address the issues of land-use planning and conservation in particular by minimizing the environmental problems arising from misuse. The data were generated and integrated using GIS Arcinfo/Arcgis 9.2. The information layers used included maps of both soil and topography (slope classes) as well a land use map. The latter component was obtained by the digital processing of ASTER images. The analysis showed that the Bv (Basaltos vermelhos) soil units, with a loam-clay-sandy texture, occur on the plains (slope; 0-3%) and cover most of the study area (172.8 km2, 30.1%). This soil was rated as Class IIIs-p/f when evaluated using the land-use capability system 2ab(c), indicating that it is adequate for the cultivation of annual and even perennial crops. However there exist problems regarding the depth of the soil and its low fertility, because of this limited depth it is not recommended to use heavy mechanization. The second soil unit, which occupies a considerable portion of the study area (154.9 km2, 26.9%), consists of the coluvionares soils (C). They occur in regions with mildly to considerably undulating relief and are included in the subclass IVs-sl/so. These soils are limited by their salinity, sodicity and flood risk.<br>Mestrado<br>Análise Ambiental e Dinâmica Territorial<br>Mestre em Geografia

To understand the territory of fast-growing cities, where there are multiple stakeholders involved, the observation of such dynamics seems indispensable to formulate and implement policies and actions based on a better understanding of these territorial systems. This chapter offers a perspective on how urban territories should be observed through geoinformation technologies that can provide a means for creating monitoring indicators concerning land use of fast-growing cities. The city of Maputo was used as an experimental laboratory for the use of geoinformation technologies in the observation, discussion, and reflection on methods for sustainable urbanism. The discussion includes the implications of the case study and possible developments to take a step forward in land use planning processes to achieve the desired socio-spatial equality.

While the savannah elephant (Loxodonta africana) is listed by the International Union for Conservation of Nature (IUCN) as “vulnerable” because of declining abundance in some regions of Africa (Blanc 2008), populations in some protected areas of South Africa are growing rapidly (van Aarde and Jackson 2007). These populations can cause extensive modification of vegetation structure when their density increases (Owen-Smith 1996; Whyte et al. 2003; Guldemond and van Aarde 2007). Management methods such as culling, translocation, and birth control have not reduced density in some cases (van Aarde et al. 1999; Pimm and van Aarde 2001). Providing more space for elephants is one alternative management strategy, yet fundamental to this strategy is a clear understanding of habitat and landscape use by elephants. Harris et al. (2008) combined remotely sensed data with Global Positioning System (GPS) and traditional ethological observations to assess elephant habitat use across three areas that span the ecological gradient of historical elephant distribution. They explored influences on habitat use across arid savannahs (Etosha National Park in Namibia) and woodlands (Tembe Elephant Park in South Africa and Maputo Elephant Reserve in Mozambique). The researchers focused on three main variables—distance to human settlements, distance to water, and vegetation type. The authors used Landsat 7 ETMþ imagery to create vegetation maps for each location, employing supervised classification and maximum likelihood estimation. Across all sites, they recorded the coordinates of patches with different vegetation and of vegetation transitions to develop signatures for the maps. Elephants do not use all vegetation types, and it can be expedient to focus on presence rather than both presence and absence. Accordingly, the researchers used GPS to record the locations of elephants with the aim of identifying important land cover types for vegetation mapping. The authors mapped water locations in the wet and dry seasons using remotely sensed data and mapped human settlements using GPS, aerial surveys, and regional maps. They tracked elephants with radiotelemetry collars that communicated with the ARGOS satellite system, sending location data for most of the elephants over 24 h, and then remaining quiescent for the next 48 h to extend battery life.
