flooding is a threat along rivers and in areas of reclaimed coastal land, protected from the sea by concrete dikes
Environment - current issues:
the environment is exposed to intense pressures from human activities: urbanization, dense transportation network, industry, extensive animal breeding and crop cultivation; air and water pollution also have repercussions for neighboring countries; uncertainties regarding federal and regional responsibilities (now resolved) had slowed progress in tackling environmental challenges
