Housing is the most important element of the city, which is of great importance in the sustainable development of the city. Therefore, achieving sustainable housing in order to enhance and improve the quality of life of the present and future generations is a major issue. Housing from various perspectives, including architecture, construction of buildings, residential buildings, land and building costs, housing loans, housing market, housing regulations, house prices, Desirable housing, etc., can be considered. On the other hand, housing is the most important concern of the present-day human being and its most important function is economic performance. And its most important function is economic performance. The housing situation and the analysis of housing prices are of particular importance, because the main goal of urbanization is to create human settlements and, among the various uses of urban land, residential use is of particular importance. Also the share of housing is also significant in quantitative term. One of the indicators for measuring poverty is housing. Good and adequate housing is a housing that does not have too much density. And, in many cases, housing and environmental conditions are the most important factor affecting on level of satisfaction of a person in a neighborhood. Apart from the social class and economic conditions of individuals, housing is always one of the most important needs and priorities of the household. The main factors  that have led to provide a place to live become a crisis, especially for low-income groups, are: Rapid population growth, a sharp increase in urbanization rates, lower household size, higher rates of profitability of the land market and housing, reduced demand for housing, reduced access rates and poor financial capabilities of the poor, the plummeting market of land and housing to the detriment of low-income groups, the reduction of land and housing supply, the lack of attention of the private sector and, ultimately, unsuccessful government policies. In spite of various experiences to address the problem of disadvantaged low-income groups, the root cause of this problem is the need to examine its structural factors. This paper has been conducted with the purpose of providing a affordable housing pattern for vulnerable urban areas with a sustainable development approach in the Mehregan township of Mashhad Metropolis detachable area using a descriptive-analytical method of applied type. The population of the study is 366 people based on the Cochran formula. Using descriptive and inferential statistics from the completed questionnaires, experts have been analyzed using non-parametric and parametric statistical methods. Since housing is a cross-domain and multidimensional domain, the attitude to it must be all-round and multi-dimensional. Hence, effective policies in the field of housing for low income groups regarding the potential of the marginal areas of Mashhad for system effectiveness will be considered. Finally, in the city of Mehregan, we can solve this problem, By drafting urban planning, architecture and housing construction in accordance with international standards and enhancing their flexibility and encouraging activities in marginalized fabric for the benefit of low income groups and changing the views and plans of urban development projects.

Nos últimos anos, tem aumentado a frequência dos desastres naturais na Amazônia, concomitantemente com a necessidade de estimar os seus prejuízos econômicos. Este trabalho tem como objetivo verificar qual é o tipo e a intensidade do impacto das inundações de 2009, consideradas as maiores já registradas na Amazônia, no crescimento do Produto Interno Bruto (PIB) municipal. A metodologia consistiu na análise de correlação linear entre o desempenho econômico e algumas variáveis referentes ao tipo de inundação e indicadores socioeconômicos. Os resultados mostram que as inundações bruscas são as mais problemáticas em longo prazo. As principais estratégias a serem adotadas perpassam pela inclusão de ações de mitigação de desastres naturais ao planejamento do desenvolvimento sustentável da Amazônia. Palavras-chave: Produto Interno Bruto.

This work have the objective of check what is the type and intensity of 2009 floods impacts, considered the major already registered in Amazon, to the increase of municipal Gross Domestic Product (GDP). The methodology was the linear correlation analysis between the economic performance and some variable relative to inundation type and socioeconomics indicators. The results bring which the fast floods are the major problem in the long term. The means strategies to be adopted are the inclusion of natural disasters mitigation actions in plan of sustainable development of Amazon. Keywords: Gross Domestic Product. Flood.

AbstractLoss and damage from climate change, recognized as a unique research and policy domain through the Warsaw International Mechanism (WIM) in 2013, has drawn increasing attention among climate scientists and policy makers. Labelled by some as the “third pillar” of the international climate regime—along with mitigation and adaptation—it has been suggested that loss and damage has the potential to catalyze important synergies with other international agendas, particularly sustainable development. However, the specific approaches to sustainable development that inform loss and damage research and how these approaches influence research outcomes and policy recommendations remain largely unexplored. We offer a systematic analysis of the assumptions of sustainable development that underpins loss and damage scholarship through a comprehensive review of peer-reviewed research on loss and damage. We demonstrate that the use of specific metrics, decision criteria, and policy prescriptions by loss and damage researchers and practitioners implies an unwitting adherence to different underlying theories of sustainable development, which in turn impact how loss and damage is conceptualized and applied. In addition to research and policy implications, our review suggests that assumptions about the aims of sustainable development determine how loss and damage is conceptualized, measured, and governed, and the human development approach currently represents the most advanced perspective on sustainable development and thus loss and damage. This review supports sustainable development as a coherent, comprehensive, and integrative framework for guiding further conceptual and empirical development of loss and damage scholarship.
