Governments shape the future of communities by defining development strategies for nations and regions. These governmental plans and programmes, as well as policies and legislation establish the basis for future decisions on projects in such diverse fields as agriculture, energy, industry, transport, regional development, land use, waste management or water management. It is obvious that these strategic documents have a big influence on future decisions that affect people’s lives. Thus it is crucial that environmental and health considerations are among the decision-making factors. To ensure this, many countries apply a systematic and anticipatory planning tool called Strategic Environmental Assessment, or in short: SEA.
