The vast majority (approximately 75%) of the population in Madagascar falls below the world poverty line of $1.90/day. I think the main problem is food.
Here's an interesting article that was just recently published:
A nutrient-rich traditional insect for improving food security and reducing biodiversity loss in Madagascar and sub-Saharan Africa

My summary: Researchers were able to harvest an edible insect that would eat the tops of a specific crop without destroying the yield. In essence, the crop yielded more food without having to cut down more crop space. They were able to combat deforestation
and malnutrition

Here's a quote from the article: "In Madagascar, native

I think many studies are showing that insects are the future of food. Many countries have been doing this for thousands of years. Madagascar's main issues are hunger and malnutrition. Many adults have signs of stunted growth or bone issues due to a lack of food.
@leedragon, the implementation of the first article is relatively recent, but it looks promising. If they are able to get all of Madagascar to adopt this method of harvesting food, the lemurs and fossas should be safe (as well as chameleons). I honestly think that mammals will always be the first to go when it comes to people hunting them to extinction. Once the mammals are gone, then chameleons may be next.
