Stacked up Inga firewood at Aladino's house - The sheer amount of firewood Inga alley cropping can produce is incredible. Aladino got all this, plus as much again which they haven't stacked yet, from pruning just a small section of his Inga alleys.
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.
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.
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.
'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.
