Transboundary environmental problems (i.e. environmental problems that affect more than one country across their borders) need negotiated discussions in oirder to arrive at consensus solutions that will then be implemented by all concenting or signatory countries. This is especially true for problems than are global or affect a large number of countries. Such negotiated solutions - called "Multilateral Environmental Agreements" - are usually formulated under the aegis of the United Nations and include scientific data gathering, negotiations, discussions, global conferences, and an Agreement document that is signed by concenting countries. The best known of MEAs, is of course the UN Framework Convention on Climate Change (UNFCCC) under which the Paris Agreement was promulgated in December 2015, and along with the MEAs on biological diversity and dersertification, form the "Big Three" MEAs.

Each issue is critical in its own right, yet they are deeply interconnected. Climate change accelerates biodiversity loss and land degradation; biodiversity loss weakens the natural systems that regulate climate; and desertification diminishes the planet's capacity to sustain both people and ecosystems. Together, they form a triad of global crises that demand integrated and cooperative responses, linking science, policy, and community action to secure a sustainable future for all.
