Wildfires are any unplanned or uncontrolled fire affecting natural, cultural, industrial and residential landscapes (adapted from FAO, 2010).

Deforestation is the conversion of forest to other land use independently of whether human-induced or not (FAO, 2020).

Forest invasive species are any species that are non-native to a particular forest ecosystem and whose introduction and spread causes, or are likely to cause, socio-cultural, economic or environmental harm or harm to human health (adapted from FAO, 2015).
