No 70 Planting Inga alleys on steep slopes with Honduran farmers

Rainforest Saver supports several projects to spread Inga alley cropping in Honduras. Each takes a different approach to the dissemination of this sustainable farming technique, which is designed to replace the destructive practice of slash and burn farming.

We have reported more recently on FunaVid, managed by Dr. Dodson, and Dr. Guillermo Valle’s schools’ projects. So this is about Marco Valle’s work with some local farmers.

Marco Valle’s project

Marco has been a partner of Rainforest Saver for several years. He began working with a local farmer, Mr. Perez, on a steep hillside in the Cangrejal Basin about 3 years ago. The steep sloped land has been planted with Inga in batches over these years and now has about 2500 Inga trees of various ages on it.

The oldest Inga trees were pruned for the first time in September 2015. Beans were planted in the pruned Inga alleys in October.

The larger branches make good firewood for the kitchen, and the remainder is left on the ground as mulch.

The first pruning did not provide a lot of mulch. It has to build up over several prunings. So this first crop was not very good, as the land was very degraded to begin with. Marco found that out when he tried to grow beans and tomatoes there earlier, before the Inga had been pruned, and got no crop at all. So any crop is an improvement, but we expect to get a bigger crop in the future when more mulch has built up.

Some of the Inga trees on Mr. Perez’s land have flowered and produced pods. Unfortunately some of these were lost when strong winds broke one of these trees, and birds have been helping themselves to the Inga pods too.

Environmentally destructive slash and burn shifting agriculture remains widespread in the region.

Productive sustainable agroforestry relieves the human pressure to slash and burn the rain forest for unsustainable shifting agriculture.

We would expect that neighbouring farmers would want to try the Inga system when they have seen a few good harvests in the demonstration plot. However, Marco has been able to persuade two farmers nearby to start Inga alleys already.

All these plots will serve as demonstration plots to expand the Inga technique to many more farmers in the surrounding area.
