Key messages

  • One study evaluated the effects, on vegetation or human behaviour, of lobbying/campaigning/demonstrating to protect marshes or swamps. The study was in Brazil.








  • Human behaviour (1 study): One study in Brazil reported after lobbying local and national governments, a wetland complex was designated as a sustainable development reserve (rather than being strictly protected) and a sustainable development research institute was created.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A study in 2008 of a wetland complex in northwest Brazil (Sellamuttu et al. 2008) reported that following lobbying of national and local governments in the 1990s, the area was designated as a sustainable development reserve (in 1996) and a new research institute for sustainable development was created (in 1999). The sustainable development reserve designation, which allowed sustainable use of resources by local and indigenous people, was a relaxation of former strict protection. Methods: The Mamirauá wetlands are a complex of seasonally flooded forest, rivers and lakes. In the early 1990s, they were strictly protected but were faced with pressure from commercial loggers and hunters. From 1992, a conservation group lobbied the Brazilian Government to allow sustainable use of the wetlands by local people. This lobbying was backed by biological and socioeconomic studies, and supported by national and international media campaigns. The conservation group leader also personally lobbied the State Governor, with arguments about political benefits of allowing sustainable use.
