For the first time in the republican history of Peru, the presidential transition takes place in democracy, social peace, fast economic growth and favorable world markets. In other words, there has never been a better chance to build a different Peru - a richer country, more equal and governable. There are multiple ways to achieve that goal. New reforms must stem from a widespread and participatory debate, one of a common vision conceived for and by Peruvians. This book aims at making a technical and independent contribution to such debate; it summarizes the knowledge available about the challenges to be faced by the new administration. The study does not recommend silver bullets, but suggests policy options. It is based on the analysis of the current reality and in six decades of relationships with Peru, in which the Bank has implemented more than 100 projects and prepared more than 500 technical reports covering the wide range of development topics. When necessary, the study provides lessons that the Bank has learned elsewhere. The study provides a conceptual framework to the analysis of the country's 34 economic sectors and the two historical perspectives behind them. In doing so, it offers a comprehensive reform agenda that sheds light on possible priorities and courses of action.

"All over the world, in all democratic States, independently of having a legal system based on the common law or on the civil law principles, the courts – special constitutional courts, supreme courts or ordinary courts – have the power to decide and declare the unconstitutionality of legislation or of other State acts when a particular statute violates the text of the Constitution or of its constitutional principles. This power of the courts is the consequence of the consolidation in contem-porary constitutionalism of three fundamental principles of law: first, the existence of a written or unwritten constitution or of a fundamental law, conceived as a superior law with clear supremacy over all other statutes; second, the “rigid” character of such constitution or fundamental law, which implies that the amendments or reforms that may be introduced can only be put into practice by means of a particular and special constituent or legislative process, preventing the ordinary legislator from doing so; and third, the establishment in that same written or unwritten and rigid constitution or fundamental law, of the judicial means for guaranteeing its supremacy, over all other state acts, including legislative acts. Accordingly, in democratic systems subjected to such principles, the courts have the power to refuse to enforce a statute when deemed to be contrary to the Constitu-tion, considering it null or void, through what is known as the diffuse system of judicial review; and in many cases, they even have the power to annul the said unconstitutional law, through what is known as the concentrated system of judicial review. The former, is the system created more than two hundred years ago by the Supreme Court of the United States, and that so deeply characterizes the North American Constitutional system. The latter system, has been adopted in consti-tutional systems in which the judicial power of judicial review has been generally assigned to the Supreme Court or to one special Constitutional Court, as is the case, for example, of many countries in Europe and in Latin America. This concentrated system of judicial review, although established in many Latin American countries since the 19th century, was only effectively developed particularly in the world after World War II following the studies of Hans Kelsen. Of course, during the past thirty years many changes have occurred in the world on these matters of Judicial Review, in particularly in Europe and specifically in the United Kingdom, where these Lectures were delivered. Nonetheless, I have decided to publish them hereto in its integrality, as they were: the written work of a law professor made as a consequence of his research for the preparation of his lectures, not pretending to be anything else, but the academic testimony of the state of the subject of judicial review in the world in 1985-1986".

The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

In recent times what has become known as "the case of Medellín " has generated a growing interest in the international community. These urban transformation that Medellín has experimented have become a focus of attention and reference for experts in many fields, around the world. The book ́Medellin: Environment, Urbanism and Society ́, that now published the Center for Urban and Environmental Studies, Urbam, of EAFIT University is a testimony of the value given by our culture to the accomplishments of the city, to the idea of the public sphere and the growing relationship between the technical sphere and the political sphere, understood in the broad sense as a form of disciplinary knowledge and construction of civil society. This book brings together a knowledge of the city from multiple perspectives; knowledge that is, without any doubt, impressive for its extension and profoundity, as well as for its capacity to combine objective data with conceptual reflections about the scope and impact of the different perspectives concerning the theme of urban transformation and the different actors that have participated in such processes. The book weaves a broad net over the city, its history and development, adopting a multidisciplinary vision. I think that this will be the first step in creating a speech that might finally liberate itself from the strict disciplinary boundaries, building a trans-disciplinary perspective that can amplify the urban dimension of the city. This is the beginning of a profound and complex reflection that is, at the same time, a project of knowledge and an instrument of action and participation.
