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.

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.

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.

Owe asymetrie i sprzeczności znajdują odzwierciedlenie w realizowanej przez nie wewnętrznie i poszukiwanej w przestrzeni międzynarodowej policy mix w dziedzinie ochrony środowiska. Na mapie interesów i zależności naturalnie pojawiających się w kontekście ochrony środowiska muszą być uwzględnione korzyści i koszty zewnętrzne, które stwarza polityka ochrony środowiska poszczególnych państw. Z EKC wynika, że owe korzyści i koszty nie mogą być rozłożone równomiernie, co powoduje, że istotne jest zapewnienie takich rozwiązań międzyjurysdykcyjnych, które zapewniają identyfikację świadczeń opartych na wzajemności zgeneralizowanej i realizację ich w jakiejś formule wymagającej międzynarodowego porozumienia o wymianie świadczeń w postaci kooperatywnych elementów polityki ochrony środowiska oraz transferów finansowych. Wzajemność, o której w tym wypadku mowa, ma charakter zgeneralizowany. Jej funkcją jest zapewnienie takich równowag Nasha, które długookresowo zapewniają najwyższy poziom efektywności. Jakkolwiek wyzwala to pewien stopień niekooperatywności w krótkim i średnim okresie, to jednak nie jest ona zupełna, gdyż fundamentalne, długookresowe cele polityki środowiska większości państw są podobne.
