KM-A4 Invasive alien species can add to 
marginalization and inequity, including, in some 
contexts, gender- and age-differentiated impacts 
{A5, A6}. People with the greatest direct dependence 
on nature, including those involved in gender- and agespecific activities, such as fishing or weeding, may be 
disproportionately affected by invasive alien species. 
More than 2,300 invasive alien species are found on lands 
managed, used and/or owned by Indigenous Peoples 
across all regions of Earth, threatening their quality of life 
and often leading to general feelings of despair, sadness 
and stress. Indigenous Peoples and local communities, 
ethnic minorities, migrants, and poor rural and urban 
communities are disproportionately impacted by invasive 
alien vector-borne diseases. Biological invasions negatively 
affect the autonomy, rights and cultural identities of 
Indigenous Peoples and local communities through the loss 
of traditional livelihoods and knowledge, reduced mobility 
and access to land, and increased labour to manage the 
invasive alien species. Impact reports by some Indigenous 
Peoples and local communities document 92 per cent
