Governments were warned to rethink the way they deal with international issues to boost global benefits in areas such as disease control, pollution reduction and crisis prevention. A study for the United Nations Development Program (UNDP) said : "Global concerns are penetrating national agendas and national concerns are becoming the subject of international debate and of policy coordination." The report by a team of international experts including Nobel Economics prize laureate Amartya Sen, added : "Today, concrete outcomes and targets - such as disease control, pollution reduction, crisis prevention and harmonised norms and standards matter."
