Yes bamboo wood dry faster and can burn well but bamboo stick or wood can not give the heat needed in those countries. Bamboo wood burns like fuel. It does not last
Some have recommended selectively burning bamboo to transform it into charcoal, which will last longer. I have seen people burn wood inside a 55 gallon drum to make charcoal. Its an interesting process. Here is a video clip on youtube of charcoal being made via primitive means:

If its produced in high quantities, the price will decline and supply will become plentiful enough to perhaps offset its fast burn time. The fast growth rate and ease of replenishment carries potential to offset observed negatives.
Paulownia is said to be one of the fastest growing trees in the world. That could be another option to target sustainable firewood markets. Which would not involve chopping down old growth forests. And would be easiest to develop and replenish with time being a factor.
