Klabin is one of the oldest tree plantation and paper producing companies of Brazil, starting their activities in Paraná and now active in 8 Brazilian states and in Argentine. In Paraná, peasant populations and rural workers started in 2011, in collaboration with a Federal Education Institute, to survey the problems and conflicts around industrial tree plantations expansion in the region, especially in the Imbaú municipality (40% of municipality occupied by eucalyptus and pine plantations providing the mills of Klabin), also in relation to Klabin´s expansion plans. In 2011 a commission of affected people started to meet and organize a survey of impacts of the tree plantations in the municpality of Imbaú. In 2013 a big seminar was organized in Imbaú to present the results. The result was a social map of the impacts, including rural exodus and confinement of the communities, cultural impacts, water shortage and impacts on food sovereignty, impoverishment of soil and biodiversity. A 'regional commission of affected people by the green desert' was formed that tries to influence the local authorities to restrict the expansion of Klabin and repair the impacts.
