'Little by little,' Faustino patiently tells me, 'we can change people's minds.' And it seems to be working - this plot here has just been planted with several thousand little Inga seedlings by a family that Faustino has helped persuaded to give up slash and burn.
Faustino keeping an eye on this years maize crop which is coming on really well. His Inga plot is now 7 years old and going strong.
When we called in on Faustino we found him busy harvesting coconuts, which he happily shares with us once he's made it safely back down to solid ground.
Faustino's Inga plot is now yielding huge amounts of firewood each year. Some of the logs they have just cut are more than 20cm in diameter - not bad after just 7 years! Just by selling some of this firewood, they will be able to cover all their costs for their maize crop.
Faustino with this years maize harvest - total organic and virtually weed free thanks to the now 7 year old Inga alleys.
Four years on and those Inga seedlings planted by Aladino at the end of the film are now a forest of sturdy 5m high trees. The soil is fertile and the ground is covered by a thick layer of mulch which has all but defeated the grass and weeds.
Making plans - Aladino is planting Cocoa seedlings in this section of his Inga alleys. As these trees like around 30% shade we helped Aladino to prune back most of the trees in these alleys today.
Even though we pruned trees from just 2 alleys today, it still produced a huge amount of firewood for Aladino and his family can use to for cooking.
This area, just beside Aladino's plot, is completely covered by towering strands of head-high grass. Yet within Aladino's 4 year old Inga alleys, the ground is covered by thick leaf litter with just the odd few weeds managing to survive, demonstrating the remarkable ability of Inga to suppress the aggressive, rapidly growing grasses.
Check out the fantastic amount of firewood Faustino and his wife got from pruning their Inga alleys to plant this year's maize. And this isn't even all of it, there's plenty more that still needs to be carried down from their plot.
