Madagascar is a priority country for conservation and preserving Earth’s biodiversity riches threatened by a rampant rate of habitat destruction. Ninety percent of the natural habitat of Madagascar has been destroyed and 91% of the lemur species are critically endangered, endangered or threatened.
Since the political turmoil of 2009, coupled with security issues and illegal extraction activities, the conservation situation has worsened. The presidential election that took place in January offers hope that this new regime will make preservation of the unique wildlife of Madagascar a priority.
President Andry Rajoelina ran on a platform of eliminating poverty for his people.
Ecotourism is good for the economy, but there are doubts if it is enough. Our conservation teams in the Ranomafana region are hoping that we have a solution for improving local economies.
Centre ValBio (CVB), a 30-year-old research center, is nestled overlooking the Ranomafana National Park rainforest near Fianarantsoa, and is an eight-hour drive from the capital Antananarivo.
CVB is a hub of modern science with laboratory equipment to study genetics, infectious diseases and mapping from satellites.
Substantial efforts by scientists have led to an improved understanding about taxonomy, species distributions, the evolution, behavior and population size of the flora and fauna, and the impact of habitat loss on Madagascan biodiversity.
This knowledge has been successfully used to guide conservation planning and action, as well as new discoveries in medical science. Scientists investigate the impact of anthropogenic influence, edge effects, climate change, and fragmentation on ecosystems and communities in these lush rainforests.
The CVB campus has five buildings and a staff of 130 local scientists, technicians and administrators who work year-round on research, training and conservation.
This station conducts studies of cyanide-eating lemurs, climate change, new leech species, lemurs that have genes that might be related to diabetes and Alzheimer’s, and genetics of an ecosystem.
All around, the parks, forests and the rare species within them are still disappearing. Slash-and-burn agriculture is the main threat to rainforests in Madagascar.

Forests are sacrificed to plant rice, the staple food for humans.
CVB has launched an alternative against this destruction of natural resources. First, the village elders are engaged to ensure a buy-in by the communities.
If the villagers are enthusiastic, workshops and training begin in the fields.
Next, using years of botanical knowledge, the reforestation team (technicians and scientists) helps villagers plant endemic saplings of tree species eaten by lemurs. We don’t plant a monoculture, but rather use natural dispersion as a guide.
We know from our pilot experience that it takes about 15 years for the endemic trees to fruit and flower, and for birds, bats and lemurs to return to these ‘new forests’ where they could help ‘plant’ more forests by dispersing their seeds.
We are hoping that this strategy will help to stabilize the soil, prevent erosion and river silting, and expand the habitats for wildlife.
But what value do these trees have for the Malagasy farmer?
Using these trees as structure vines of high value crops such as vanilla, wild pepper and cinnamon that need shade to grow well are transplanted onto these trees.
With assistance in processing and marketing, the local farmers can harvest these high-value crops and earn great economic gain.
The prices of Malagasy spices are high in the world market and spice venders project that the high prices will continue into the future with new markets in China and India.
There is hope that not only will this strategy increase biodiversity, but it will also bring affluence to the farmers and merchants of Madagascar.
Rajoelina’s promise of prosperity is possible and the unforeseen benefits could be transformative.
