The problem to be addressed in this article is related to the precautionary principle and its incorporation into the Brazilian law. As it is beknown, this principle has been widely cited by Brazilian case law and it is an important part of the legal and environmental scholarly production. However, it follows that its application has been made fairly randomly, and even so there is no clear and operational definition of its content. The hypothesis being examined is that since the Rio Declaration's - in its translation into Portuguese - environmental legislation has termed as legal principle, which internationally is an approach, a precautionary measure, as can be seen in both the texts in English and French of the Rio Declaration and other relevant legal instruments. The methodology to be used is the research of the case law and relevant legal rules, as well as the examination of the scholarly production on the subject. As a result, the conclusion is that there is an overuse of the precautionary principle by the Brazilian courts, especially by the Superior Court of Justice and that, in this case, the Federal Supreme Court has played a moderating role in relation to the application of the precautionary principle.

The Environmental Kuznets Curve (EKC) is a descriptive formula used to reflect on asymmetries in economic development and consequential conflict of interests arising between various states of the world. These asymmetries and conflicts of interests have their reflection in these states' environmental policy mix - implemented domestically and pursued in the international context. The emerging map of mutual interests and dependences results from the consideration of external costs and benefits pertaining to respective national environmental policies. The EKC makes it evident that these costs and benefits cannot be evenly spread over all the states. This urges these states to adopt such interjurisdictional arrangements which are based on the identification of a possible multilateral exchange of economic policy favours and international financial transfers. Such an exchange, whenever occurs, has a generalized reciprocity formula. The function of such an arrangement is to make it possible for Nash equilibria to emerge, as such are most likely to produce the highest possible level of effectiveness in the long run. Such a behavior may not be cooperative in the short and medium term, yet the bottom-line cooperativeness is achieved because most states have similar if not the same long-term environmental goals.

This work analyzes the Agenda 2030 in its main potentiality to lead public policies and private actions towards a more sustainable path. At the same time it acknowledges its dependency on measurements and finance mechanisms for the Sustainable Development Goals implementation. The main argument is that public expectations face difficulties to be translated in public actions, due to, among other factors, the lack of measurement and finance mechanisms. With this purpose it starts describing what is the Agenda 2030, and how this United Nations lead international declaration is structured to be monitored and implemented by States and others multi stakeholders. Secondly it analyses the importance of the measurements to address critical social environmental challenges and to allow comparison between the achievements of each member state. Third it remarks the role-played by international financial institutions, by international investment and by the private sector in general. Forth, the article highlights the drawbacks the methodology of goals can represent when used to overcome collective challenges marked by moral issues and diffuse impacts, being highly dependent on measurements and finance tools. The methodology chosen was the descriptive and normative, the techniques used were documentary, legislative and bibliographic research.

Adjusting the legal status, and support policies for migrant workers is an issue on the agenda of international institutions for nearly a hundred years. The first efforts to protect foreign workers have been taken during the first session of the International Labour Conference in 1919. In the following decades ILO activities has led to the preparation of three international documents concerning this issue (non-binding ILO Convention No. 66 in 1939, and Convention No. 97 of 1949, and No. 143 of 1975). For many decades, the problem of the protection and assistance of migrant workers' rights was considered as a narrow issue of international labor law. Codification efforts, undertaken during seventies, has led to the adaptation of the UN document (International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families) in 1990, and inclusion this issue into more general area of international human rights law. Despite this fact, and the existence of several categories of documents concerning migrant workers within Council of Europe, the European Union, and even ASEAN, the protection of migrant workers has never been effectively functioning system. The aim of this article is the analysis of the codification of that issue, and the main obstacles to consensus on the protection of migrant workers' rights. The state parties of the UN Convention contains primarily countries of origin of migrants (such as Mexico, Morocco and the Philippines). It seems, therefore, that despite 46 ratifications the, UN convention does not have a global character, and activities of its monitoring body (Committee on Migrant Workers-CMW) reflects primarily demands of sending countries. The article closely examines particularly controversial provisions of the ILO and UN documents from the point of view of current labour migrations and policies of sending and host countries.

The eco-friendliness achieved several spaces in society, also reaching the government as a response to the pressures exerted by international organizations, but also by society itself, demanding compliance with the legislation, seeking to develop better environmental quality and promote the municipalities reactions that seek answers to these requirements because for decades that environmental responsibility was focused only on federal and state government levels. However, in 1997, the National Environmental Council (CONAMA), by Resolution No. 237/1997, establishing the evaluation of local environmental impacts of projects for competence of municipalities, which must coordinate actions, developing environmental education for understanding and community respect for the environment, implementing regulations to control environmental deterioration, enabling a reduction of degraded areas, thus taking the mission to stimulate local sustainable development with social equity, economic development and environmental protection.

This book explores the issue of environmentally-induced migrations from the point of view of international human rights law, international humanitarian law, international refugee law and international law of statelessness. Last few years have become a period of unprecedented growth in the number of studies devoted to the forced migration caused by climate change. The book by professor Jane McAdam, published by Oxford University Press, differs significantly from previous studies in this area. The focus of the author became a state responsibility for the situation of climate-change induced displaced people with a particular focus on legal aspects of this problem. The basis of the author`s considerations are four particular areas of public international law: international human rights law, international humanitarian law, international refugee law and international law of statelessness. The issue of climate change-induced displacement is now becoming a growing challenge for public international law. The growing number of climate change migrants becomes a challenge for the international istitutions dealing with humanitarian assistance. Sea level rise become a factor of specific legal problems, such as climatic deterritorialization of the state, state succession on the new territory, the status of people forced to leave their country submerged under the waters of ocean (forced migrants?, refugees?, stateless people?, citizens of the former country continuing its status within a new territory?).

The European Union does not have an autonomous and self-standing public policy concerning the protection of landscape. Instead, it adopts fragmentary and incidental measures meant to protect landscape. These measures are adopted within the frameworks of other EU policies, most importantly the EU environmental policy as well as other policies which are integrated with it (such as agricultural policy or policy concerned with special planning). In all these realms, the EU shares its powers with its member states. In some important areas, such as e.g. the property regime, the member states retained their exclusive competences. This particular distribution of powers makes the implementation of the extra-EU international law instruments rather difficult and not sufficiently effective to produce a worthwhile impact. These obligations have a limited influence because most of them are obligations of "a diligent pursue" rather than "firm result". As such, they are unlikely to give rise to direct application of respective conventional provisions. Notwithstanding, their importance is much more pronounced in the area of legal reasoning, where even the EU or domestic measures have to be interpreted in the light of the EU and/or its member states' obligations arising from international conventions on landscape protection.

Habermas discusses the chances for the establishment of world citizenship in contemporary society, marked by multiculturalism and the process of globalization. Habermas identifies the historical configuration of the post-national constellation, and from there themed the transition from international law to the law of citizens of the world, which aligns the concept of citizenship to the idea of ​​human rights. Habermas analyzes the Kantian idea of ​​a cosmopolitan state in which citizens are legal subjects of their respective States and members of a cosmopolitan entity. Kant elaborates on the concept of world republic, which Habermas disagrees with, but offers the example of the European Union for a discussion on the realization of a just and peaceful international order. Based on the Kantian orientation of constituting an order of world citizenship, Habermas discusses the conformation and viability of this idea in contemporary times. For Habermas, it is possible to spell out the idea of ​​cosmopolitan citizenship. From the European Union, cooperation between States and citizens shows that a cosmopolitan community is needed to complement an international community of States.

The planning and implementation of legal units of environmental management have been
conflicting, generating social and economic predicaments. These conflicts generate cognitive, emotional and
affective movements, that somehow contribute to learning with the operation. The Environmental Education, as
a mediating process, enables the collective construction of the sustainable development process for the
productive sectors, with an open methodological proposal, whose model is to generate solutions from social
participation. In this sense, it is understood that Environmental Education is a process of educational praxis that
aims at building values, attitudes, concepts, skills, standards, knowledge and shared practices for the constructing
a style of thinking that contributes to environmental citizenship. Trying to understand and contribute with this
social dynamics, have been conducted, from 2001 to 2006, numerous and multiple environmental teaching
actions in the highlands region of Santa Catarina. This movement resulted in the development of an open model
of environmental education which is mediated by the environmental perception of social actors involved,
understanding perception as the integration of biological, psychological and social dimensions. Thus, the
proposition for the Open Model of Environmental Education with the paradigm of transdisciplinary opening
mediated by the environmental perception of social actors involved will result in the collective construction of
solutions to local environmental problems.
