Review Questions

• How does UNCLOS define maritime boundaries and what implications do these definitions have on international relations?
  • UNCLOS defines various maritime boundaries including territorial seas and exclusive economic zones (EEZ), impacting how nations interact in terms of resource rights and navigation. For instance, the establishment of an EEZ gives coastal states significant control over marine resources while still allowing for certain navigational freedoms for other countries. This framework can lead to disputes when countries overlap in their claims or when new resources are discovered, highlighting the importance of UNCLOS in shaping international relations.
• Evaluate how UNCLOS contributes to environmental protection in maritime areas.
  • UNCLOS includes several provisions aimed at protecting the marine environment by promoting sustainable practices and preventing pollution from ships. It obligates states to take measures to prevent marine pollution and manage marine biodiversity effectively. By creating a legal basis for conservation efforts and establishing guidelines for managing human activities in ocean areas, UNCLOS plays a vital role in balancing economic interests with environmental protection.
• Assess the challenges faced by UNCLOS in enforcing maritime laws and resolving disputes between nations.
  • Despite being widely accepted, UNCLOS faces challenges such as differing interpretations of its provisions and varying levels of commitment among nations regarding enforcement. Some countries may not recognize certain claims made under UNCLOS or may act unilaterally to exploit resources without consideration for international agreements. Additionally, resolving disputes can be complicated due to geopolitical tensions and national interests. The lack of a centralized enforcement mechanism means that compliance relies heavily on cooperation among states and their willingness to adhere to international norms.
