Shared water resources in South Asia face various challenges including scarcity, population growth, and climate change impacts on all the riparians. Consequently, national calls for water security have become louder. As a result, collaboration among the nations of South Asia for ensuring equitable sharing of such water resources has not been optimal. While most countries do not have reliable systems for data generation, those possessing some hydrological data consider them state secrets, restricting their exchange. Even when treaty obligations exist, data-sharing practices are
ad hoc, and the range of information shared is limited. Thus, negotiating new transboundary water treaties amongst South Asia’s riparian countries has become a daunting task, and enforcing existing ones remains a real challenge.
The book describes and analyses how environmental issues are regulated in several federal, regional and unitary systems and in the European Union. The comparative analysis reveals common trends towards a multi-layered environmental governance, cross-cutting traditional distinctions among different state models.
In the second part, the case study of the management and protection of water resources is selected and analysed in the same legal systems. Disaggregating environmental protection into more specific competence fields allows trends and challenges to be tested
The book casts light on the relationship between the state models as to the division of powers and environmental governance. It develops theoretical and practical foundations of contemporary, multi-level environmental law and challenges consolidated approaches in federal studies.
