The challenges of monitoring the effects of deforestation on the Amazon are immense. The vast areas which need to be covered means it's difficult to keep tabs on what's happening on the remote fringes of the rainforest and news of illegal logging and other environmental damage can take a long time to reach the authorities, if they find out at all.
To help solve this problem, the Greenpeace team in Brazil has been training local people to map the impacts of the soya industry in the Santarém region of the forest, the heart of soya production in the Amazon. It's a collaborative project with Brazilian organisations Projeto Saude e Alegria (Health and Happiness Project) and the Rural Workers Unions of Santarém and nearby Belterra, training people to use GPS technology to pinpoint the damage caused by intensive agriculture, empowering them to help defend their land and the rainforest.
