Abstract The problem of informal areas is the most significant urban challenge facing third world countries. Most of the urban population has become informal areas dwellers. These areas consume many resources and suffer from bad conditions. Therefore the need arose to transform them into sustainable societies in order to save resources and improve their quality of life. This paper discusses the sustainability as means of achieving quality, efficiency and improvements in informal areas using the three pillars of sustainability: social, economic and environmental. It also aims at carrying out a comparative analysis of case studies for sustainable upgrading of informal areas in Brazil and India to observe the impact on their dwellers' life after upgrading. Analysis is examined on three levels: economic, social and environmental. Moreover, the comparison and evaluation of results ends with suggestions to be applied on Egyptian informal areas in order to achieve more efficient and sustainable upgraded areas.

This paper presents international co-inventor networks as both a predictor variable of countries' ability to produce and disseminate internationally green inventions, and an alternative mechanism to support development of relevant programmes and policies in that regard. It includes cases from three developing countries with limited resources for clean technology development, Brazil, India and South Africa, which have shown successes owing to the potentials of co-inventor networks. It contributes the extent literature on this topic, which predominantly emphasizes firms' responses to conventional governments' interventions (subsidies, market price, standards, and interagency cooperation) to achieve cleaner production plans and particularly the Targets 17.6; 17.7 and 17.8 of the sustainable development goals. Broadly, such targets aim at enhancing countries' technological capabilities through partnership. The paper finds various correlations between co-inventor networks and growth of patents in solar energy, air pollution management and biofuels in the sample countries. Correlations are linear in India, followed by Brazil owing to the larger sizes of co-inventor networks but nonlinear in South Africa, which has smaller networks. The paper argues that co-inventor networks accelerate transnational exchanges of core human capital, and are fitting predictors of production and flows of green inventions. They are worth adopting in national and transnational industrial and innovation cluster policies globally to support sustainable production plans. [ABSTRACT FROM AUTHOR]

Abstract: This paper presents an overview of the current status of the main CCS initiatives in the major emerging economies: China, India, Brazil, Mexico, Russia, and South Africa. This study first covers all six countries as a group and describes their natural resources. The second part of this study embraces each country individually and includes current initiatives and current legal and technological status of CCS. At the end, this study summarizes the main findings in the emerging economies and the potential of including CCS as part of the CDM. [Copyright &y& Elsevier]

Abstract: How big a threat is global warming to climate-sensitive and economically important sectors such as agriculture in developing countries? How well will farmers be able to adapt to the threats of global warming? This paper attempts to shed light on these two important questions. A cross-sectional analysis is employed to estimate the climate sensitivity of agriculture in Brazil and India. Using panel data from both countries, the study measures how net farm income or property values vary with climate, and consequently, how farmers in India and Brazil react and adapt to climate. The estimated relationships are then used to predict the consequence of alternative climate scenarios. Global warming by the end of the next century could cause annual damages in Brazil between 1% and 39% and between 4% and 26% in India, although some of this effect may be potentially offset by carbon fertilization. These estimates do not factor into account climate-induced extreme weather events. [Copyright &y& Elsevier]
