Abstract

The droughts that hit North and North Western Europe in 2018 and 2019 served as a wake-up call that temperate regions are also affected by these kinds of slow progressing or creeping disasters. Long-term drivers, such as land-use changes, may have exacerbated the impacts of these meteorological droughts. These changes, which are spread over a long time span, may even be difficult to perceive for an individual, but make a big difference in how these rare weather events impact a region. In this paper, we introduce three long-term drivers: forest fires in Europe, global urbanisation, and global deforestation. We attempt to provide a first assessment of their trends, mainly using statistics derived from satellite imagery published in recent literature. Due to the complexity of drought impacts, and the scarcity of quantitative impact data, the relationship between drought impact and these three processes for land use change is difficult to quantify; however, hence we present a survey of the recent trends in these land use change processes and the possible mechanics by which they affect drought impacts. Based on this survey we can conclude that the extent and the number of wildfires have increased markedly in Europe since 2010. Deforestation is still occurring in the tropics, with a loss of 12% in the last 30 years but has halted in the northern regions. Urbanisation has more than doubled in the same time span in the tropics and subtropics, mostly at the expense of forests, while in Europe urbanisation took place mainly in the northern part of the continent. We can conclude that none of these implicit drought drivers followed a favourable trend in the last 30 years. With consistent and worldwide monitoring, for example, by using satellite imagery, we can regularly inform the scientific community on the trends in these drought impact affecting processes, thus helping decision makers to understand how far we have progressed in making the world resilient to drought impacts.

  • The deforestation the tropics might exacerbate drought decreased in area, while forests in the northern latitudes increased at the expense of tundra impacts in adjacent regions, due to a change in type of cloud formation and increase of and barren land

  • We reported that there is a trend of increasing wildfires in the last five years in Europe

Summary

Land Use Changes in the Last 30 Years

Drought is often perceived as mainly a meteorological driven disaster. land use can have a significant influence on the impact of a drought. We present here an overview of the most important land use changes in the last decades that are potentially relevant for current drought severity and impacts. Controversies hampertion and requirement, while cooling at the same time and decreasing need for ingwater a sustainable land use in relation to drought are, for example, irrigation, helping to drought impact and in on dry local areas, conditions during dry seasons, butfeaalso water. Covered are soilIndegradation and compaction and the role of irrigation, for which not the following sections some of the main trends in land use changes related to enough datawildfires, could be gathered through satellite imagery. Worldwide statistics on to increased temperatures and availability of dry litter Worldwide statistics on these fires these firesusing are made using satellite imagery results often leading to political debates.
