(CNN)A record 212 land and environmental defenders were killed last year, equivalent to an average of more than four per week, according to a new report from NGO Global Witness.

Colombia was the deadliest country in 2019 with 64 killings -- up from 24 in 2018 -- and was 30% of the global total last year.
Next on the list was the Philippines, with 43 killings. Brazil had 24 and almost 90% of the killings took place in the Amazon region.
Seven of the top ten worst affected nations are in Latin America, where more than two thirds of total killings took place. The region has consistently been the worst affected since Global Witness started gathering data in 2012.
It is also home to Honduras, the country with the largest percentage increase in killings, which jumped from four in 2018 to 14 last year.

Mining was the deadliest sector, with 50 people killed, followed by agribusiness with 34.
Asia was a hotspot for attacks related to agribusiness, representing 85% of the global total. Of this number, nearly 90% took place in the Philippines.
There were also 24 killings related to logging, an 8
