A new approach focusing on ＂human security＂ principles based on freedom, dignity, justice, equality, solidarity, tolerance, and respect articulated in the millennium declaration is needed. Achieving this requires a more integrated, inclusive, and comprehensive development framework that is able to analyze and understand the context with its progress and setbacks. The paper realizes that measuring MDGs achievement does not only need a comprehensive integrated approach, but also a defmition of risks and challenges that the region faces. Issues like poverty, inequality, unemployment of graduates, personal and collective insecurity due to conflict, migration, and brain drain, food insecurity, and gender inequality are all issues that need to be redefined when analyzing the region to suit the context. The paper concludes that in order to understand the context, re-definition of concepts like poverty reduction, participation, and empowerment is needed to make concepts more relevant to the context. Lastly, the paper reflects the new call from youth for a new development model that is not based on market economy, ends political economy of the rentier states, and emphasizes a productive oriented economy that is able to generate employment and decent work. It also emphasizes democratic governance as an only path for a sustainable participatory development that can realize ambitions and aspirations of the majority of population.展开更多

The main objectives of the research are focused into four interrelated issues： （1） to analyse the structural-function of the social networks of Sudanese and Egyptian migrants; （2） to explain the opportunities and challenges confronting the social networks; （3） to examine the elements of implications on SA society as perceived by the networks; and （4） to identify perceived future visions of the social network members in the context of their social and economic remittances in both countries. The research has applied a qualitative method and a structured interview sheet was used for data collection. The Sudanese sample focused on members from a Nubian social network in ]eddah who resemble skilled, semi-skilled, and unskilled labours, while the Egyptian sample selected randomly from semi-skilled youth labours and unskilled labours as informal groups. The research has found some differences in the structural functions of both groups. There are many similarities shared between the two groups in relation to conserving social ties, support and cooperation as one homogeneous socio-ethnic groups in the hosting country. Also, the results show that both groups follow similar strategies of social and economic remittances to home land. Moreover, both groups are suffering and facing many shared challenges regarding economic security and sustainability in the hosting country. While, the Sudanese group has clear vision in respect of the betterment of the migrants in SA, the Egyptian group perceives the future as gloomy and uncertain.展开更多
