A tropical paradise.
Many people do not know this, but agriculture in Papua New Guinea is not a recent development. Barely explored until the middle of the twentieth century, the people of the highlands of PNG have been practising agriculture for more than 7,000 years and may even be considered the first agricultural people in the history of humankind. In short, many landscapes in PNG have been under human influence for thousands of years. This does not, however, mean that the pressures on the landscape have remained the same. Along with PNG’s increasing integration into the globalized world, population and the need to provide food have increased, leading to a steady reduction of tree cover in these settled areas. Given how steep the highlands are, this has had dramatic effects: landslides and erosion, together with an increase of degraded grasslands, barely able to provide ground for agricultural crops, are normal sights now. It is high time to save this tropical paradise from its own downfall.
In Jimbu Province, Yongomugl subdistrict, right in the middle of the eastern highlands, a small NGO called the Voice of Yongos (VoY) has been working for years to reverse this trend. In 2017, VoY teamed up with APFNet to expand their original idea and combat a problem they had been facing in the past far too often: the unwillingness of farmers to plant trees as there is no immediate income to gain from this.
The issue, in fact, lies even deeper than just a lack of an income for a few years: aside from a main road winding its way through the mountains, many areas in need of restoration are far off the road and no farmer has time to go to the only nursery in the next larger town 1.5 hours away just to get the seedlings. Additionally, compared with other tropical economies, the rotation periods in the highlands are far longer due to ecological constraints, market demand, and social customs. Instead of 5 to 10 years, the average rotation is 15 to 30 years for most trees. This, on the upside, leads to a landscape boasting large trees and less erosion due to constant cutting, on the downside this makes the matter of earnings from trees more of a legacy business than a mid-term investment. Money has to be earned in other ways in this subsistence economy.
Over the years VoY recognized these problems and developed this project intending to tackle all of these obstacles. In order to overcome the seedling accessibility issue, the NGO built four nurseries in the area and purchased a jeep that can deliver these seedlings right to the doorsteps of the farmers. For those farmers living in remote areas, so-called “mini-nurseries”, that is nurseries that raise 10,000 seedlings instead of 40,000 seedlings per nursery, were established on mountain tops to cover as large an area as possible.
Mini-nurseries are located far off the roads high up in the mountains.
“Every small tree you see around here has been supplied by one of our nurseries, we are really changing the landscape here,” said Joe Kelly Bik, the Director of VoY. In fact there are many species such eucalyptus, white pine and patula pine trees now dotting the valley on both sides and holding it in place. It is truly a testimony to the determination of humans and the abilities of trees to resettle even degraded areas.
“If you think about it, each tree is a bioengineering project,” says a teacher at a local high school, where through the project students are taught the importance of trees to fight erosion on a smaller scale and climate change impacts on a global scale. Trees, he emphasizes, are the cheapest and most ecological tool to restore the landscape’s functionality.
Papua New Guinea is still at the beginning of its path to restoring degraded sites throughout the economy. The national government and the Papua New Guinea Forest Authority, which is also formally overseeing this project, has committed itself to increasing reforestation efforts in the coming years. The APFNet “Community Tree Planting Project”, spearheaded by VoY, will in this context be a model for how not only the community can be included in reforestation efforts, but also how short- and long-term benefits can effectively be connected.
