The number of inhabitants who are exposed to traffic noise along major roads outside urban areas is gradually decreasing. In 2017, around 16,000 fewer inhabitants were exposed to high road traffic noise levels throughout the day compared to 2012. There is an important difference between inhabitants who live in the impact area of major motorways and highways, and inhabitants who live in the impact area of major main and regional roads.

In the last decade, droughts have been slightly less intense than in the previous decade, and it is worrying that they occur most often during the growing season. Especially in the first trimester, we observe a decrease in the frequency and intensity of hydrological drought. In the period 1961–2020, the year 2003 stands out in terms of drought, which was dry in all quarters of the year. After 2000, the years 2007 and 2011 were more markedly dry.

Soil drought has a key impact on plant development and consequently on various industries (forestry, agriculture, …) . Indicators of the number of drought days and the duration of drought periods in individual years show an increase especially after 1990. Similarly, the analysis of the impact of the climate change up to 2100 shows that soil water deficits will increase in the future. The number and the duration of the droughts will increase.
