In this report we therefore present a farming project in Southern Brazil and the work of the organisation Centro Ecológico on participatory certification of organic foods. These examples show that it is possible in practice to increase food production and secure livelihoods with the help of small-scale trade and organic farming, both of which conserve and draw benefits from ecosystem services. Through being active in a range of different networks, Centro Ecológico has been able to influence the development of organic farming both nationally and internationally.
