context: The local people have traditionally utilized material from the forest, whether for use in their architecture, to make pirogues (dugout canoes), to provide fiber for weaving, to provide firewood, to gather leaves for traditional medicine, or to flavor their drinks.  Most of the residents are subsistence rice farmers who cultivate irrigated paddies in valleys or who plant on hillsides that have been cleared and burned (slash and burn agriculture, known locally as tavy).  The swamps which formerly covered vast areas of Andapa Basin have been converted to rice paddies which are intensively cultivated; however the Tsimihety traditionally practice slash and burn techniques on the hillsides in preference to irrigated rice fields.  Coffee was an important cash crop before market prices fell in the 1970s, but vanilla remains an important crop for the area.  Until the mid-2000s, vanilla prices were high, but they have since fallen off significantly.  The crash of vanilla prices, along with a rapidly growing population and steady decrease in cultivatable land, has resulted in widespread and extreme poverty.  Between January and April, before the main rice harvest, many people in the region do not receive enough food to eat.  The Sava Region, which includes Marojejy, is the poorest region in Madagascar, and in 2011, continued rises in global food pricesâparticularly that of imported riceâhas made obtaining food more difficult for rural families.Not only have international environmental organizations (such as Conservation International, Wildlife Conservation Society, World Wide Fund for Nature, and Care International) established programs to help local residents, many local people work to improve their situation through environmental and health education programs.  An increase in sustainable agriculture, silviculture, conservation awareness, and improved education and health care have also furthered the goal of protecting the environment and promoting livelihoods centered on the remaining forest.  Limited and responsible ecotourism is also seen as a long-term alternative to continued deforestation.
