“The water is everywhere before the water is somewhere”. Bruno De Meulder, Tamanduatei Studio 2017. Abstract Thinking the city of Sao Paulo, more specifically the flood plain edge of Tamanduatei river, through the perspective of water infrastructure design was our challenging mission as Tamanduatei Studio class 2017, in a context of urban redevelopment. People living in a city of 300 rivers do not have any contact with the few remaining tributaries. Existing structures can become an opportunity instead of being a burden (De Meulder 2017). Besides the geological structure, the infrastructure (highways, viaducts, roads, railways, high voltage lines, ...) have a major role in harvesting water to solve the flooding problem. Based on this background, this thesis paper highlights the potential of infrastructure in being the major motif of water urban mechanism. Moreover, the paper investigates the strategy developed in course of designing the new waterways and water plains. The first part of this thesis offers an introduction to infrastructure as landscape by referring to some literatures. The second part will be an overview of some similar cases in the world. The third part will be presenting a comprehensive analysis of the existing urban fabric at the flood plain of Tamanduatei by emphasizing on the mobility and infrastructure analysis. Finally, the fourth will analyze the strategy adopted for a sample project from the Tamanduatei studio.

This paper is a comparative study between spatial dichotomies of two bustling mega-cities that were both shaped in the mid 90’s as a result of the wave of urbanization across the world. Despite of being two different geomorphologies, the two cities have somehow transformed drastically and exhibit similar patterns of development, increasing urban migration and a similar socio-spatial division, which is distinctly visible in the image of the two cities. Through a review of various literature, this paper aims to analyse how these two important financial capitals of Latin America and Asia, today have become contested territories of irreconcilable dichotomies .São Paulo and Mumbai are examples of multiple worlds living in the city. These bustling mega cities of the urban age represent the coexistence of both the Global North and the global south within the same boundaries. Is this form of splintering urbanism in megacities like São Paulo and Mumbai becoming a ‘generic’ pattern in the developed/developing context of urbanization? Is the growing number of gated communities and exclusion of informality is creating a ridge in the materiality of the two cities? Can we by de-layering the patterns of both these kinds of settlements, link them together to a stronger network of the globalized economy? How can we prevent this multiplication of homogeneous, exclusive form of architecture in this rapidly urbanizing world? Can redefining infrastructure, together with landscape urbanism help weave these fragmented islands into a more heterogeneous habitats? What can the emerging economies learn from these two cities, and what lessons do they have to offer each other?

The present article tries to analyze the subsistence economy model having as parameter its spatial organizational relation with the landscape. The subsistence economy is a model of an economic system based on activities that aimed at the self-sufficiency of its practitioners, originating in the period prior to pre-industrialization. In this type of economy the activities that stand out are agriculture and livestock. In Mozambique, between 70% and 80% of the population lives in rural areas and has agriculture as their main source of subsistence. The territory of the Republic of Mozambique has a high potential for promoting agriculture through irrigation, but most of its production that includes vegetables and cereals at subsistence level is a rain-fed production. The Constitution of the Republic of Mozambique in its N°1 of Article 103 advocates agriculture as the basis of national development. This essay presents an analysis of the main concepts of subsistence economy, their advantages and a characterization of the current stage (essay one), and the effects of the subsistence economy on the deforestation of the landscape (essay two). As a working methodology For the accomplishment of this paper, the bibliographical consultation was carried out as well as the analysis of data collected in the field. Subsistence agriculture has been practiced in the Zambezi basin region since the earliest indigenous human settlements that settled along the banks of the rivers as a way to take advantage of this resource and by the fertility of the soils at the margin of which it was very favorable to the practice of agriculture than the highland soils where productivity was dependent on rainfall. Since then, agriculture and livestock have been playing an important role in food production and economic development. The rural population in Mozambican survives from the production of food for consumption by families whose surpluses are marketed both in rural areas as well as in urban centers. The practice models of this agriculture in the form of preparation of the soil as well as the type of planting and the conditions of the climate of the semi-arid region jeopardize this activity; The discovery of mineral resources such as coal in the region and the growing urbanization process have led some of the population to abandon agricultural production to seek employment in miners and the reduction of land available for agricultural practice. The introduction of new processes in agriculture from the family base can demonstrate that it is possible for families to remain in these regions and live with dignity in this way of life from working the land where families can produce food by ensuring and improving their diet and selling production is individual or collective. The objective of this research is to analyze the practice of farming as an activity in its various forms of income generation and self-sufficiency, taking into account its characteristics and the different types of organization (it individual or cooperative). From this research exercise, direct results are expected that can increase the yield of agricultural production and control of the animal mortality rate, taking into account the territorial constraints and the effects of the climatic changes, from a system of diversification and rotation of cultures and methods and techniques for capturing and storing rainwater and surface water.

Due to the rapid population growth in Tete province, Mozambique, where the annual growth rate is more than 4%, the population will double in the next 20 years, the demand for food and water will increase. A problem that the region is experiencing now and will increase in the future as a result of climate change, which will lead to increased periods of drought, lack of water resources, and change and unpredictability of rainfall. To meet people's needs for water and food on this wide scale, radical policies and strategies must be applied to water management. The most important of which is the recharge of groundwater, lakes, and rivers by harvesting, storing, managing and using rainwater in the dry months and significantly improving food production. Agriculture depends heavily on rainwater, but most of it evaporates before it is used or harvested. Or before penetrating the soil, or becomes runoff causing soil erosion. This paper discusses one of the methods of harvesting rainwater and employing it in agriculture "runoff farming". Which directs runoff water from rainwater harvested in non-planted areas into a restricted area for storage and residual use in irrigation during dry periods.Runoff farming has proven to be a valuable tool in dry areas to increase crop yields, promote reforestation, equal soil erosion, maximize available water resources And recharge local groundwater.The paper will review a number of examples of Runoff farming water harvesting in the world in similar conditions to Tete Province, its different techniques and results. In addition to a proposal draft demonstrating the applicability of the technology within the city of tete.
