Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored Satellite data indicate the Congo Basin lost an area of forest larger than Bangladesh between 2000 and 2014.Researchers found that small-scale farming was the biggest driver, contributing to around 84 percent of deforestation.This kind of farming is primarily done for subsistence by families that have no other livelihood options.The study finds that at current trends, all primary rainforest in the Congo Basin could be cleared by the end of the century. Africa’s Congo Basin is home to the second-largest rainforest on the planet. But according to a new study, this may soon not be the case. It finds that at current rates of deforestation, all primary forest will be gone by the end of the century.The study was conducted by researchers at the University of Maryland (UMD) in the U.S. who analyzed satellite data collected between 2000 and 2014. Their results were published today in Science Advances. It reveals that the Congo Basin lost around 165,000 square kilometers of forest during their study period.In other words, one of the world’s largest rainforests lost an area of forest bigger than Bangladesh in the span of 15 years.The Congo Basin rainforest is home to many species, such as this okapi (Okapia johnstoni), which is listed as Endangered by the IUCN and is found only in the Democratic Republic of the Congo.But why? Is it due to industrial pressure like in South America and Southeast Asia where the majority of deforestation has been done for soy, palm oil, and other commodity crops? Or commercial logging, which is razing forests on the Solomon Islands and Papua New Guinea?Not so much, according to this newest study. It reveals that the dominant force behind rising Congo deforestation, driving more than 80 percent of the region’s total forest loss, is actually small-scale clearing for subsistence agriculture. The researchers write that most of it is done by hand with simple axes.According to the authors, the preponderance of small-scale deforestation of Congo rainforest is due largely to poverty stemming from political instability and conflict in the region. The Congo Basin rainforest is shared by six countries: Cameroon, the Central African Republic (CAR), the Democratic Republic of the Congo (DRC), Equatorial Guinea, the Republic of the Congo (RoC) and Gabon. Of these, the DRC holds the largest share of Congo forest – 60 percent – and is home to more people than the other five combined. The DRC, along with CAR, has a human development index in the bottom 10 percent, meaning that lifespans, education levels and per capita GDP there are among the lowest in the world.Three-year moving average of annual forest loss area for the major disturbance categories in all countries. Image from Tyukavina et al., Sci. Adv. 2018;4: eaat2993With few livelihood options, most people survive by carving farmland out of the forest. These plots are farmed until the soil runs dry of nutrients, whereupon a new plot is cleared and planted.Before now, it wasn’t exactly understood how much this type of smallholder farming called “shifting cultivation” and other forms of small-scale agriculture were contributing to overall Congo deforestation. So UMD researchers looked for patterns signalling different types of deforestation in regional tree cover loss data captured by satellites.According to study coauthor Alexandra Tyukavina, “it was important for us to explicitly quantify proportions of different drivers, to demonstrate just how dominant the small-scale clearing of forests for shifting cultivation is within the region, and to show that it’s not only re-clearing of secondary forests, but also expansion into primary forests.”  Tyukavina is a post-doctoral associate at UMD’s Department of Geographical Sciences.Tyukavina and her colleagues found that small-scale forest clearing for agriculture contributed to around 84 percent of Congo Basin deforestation between 2000 and 2014. When zooming in on the portions contained only in the DRC and CAR, that number goes up to more than 90 percent. The only country where small-scale agriculture isn’t the driving force of deforestation is Gabon, where industrial selective logging is the biggest single cause of forest loss.The study also reveals that the majority – 60 percent – of Congo deforestation between 2000 and 2014 happened in primary forests and woodlands, and in mature secondary forests.Pre-disturbance forest type.

Adv. 2018;4: eaat2993The United Nations projects that there will be a fivefold increase in human population in the Congo Basin by the end of the century. The researchers found that if current trends hold, this means that there will be no primary Congo rainforest left by 2100.In their study, the researchers also warn of “a new wave” of large-scale clearing for industrial agriculture. While contributing a comparatively scant 1 percent of Congo deforestation during the study period, it appears to be trending upward, particularly in coastal countries.“Land use planning that minimizes the conversion of natural forest cover for agro-industry will serve to mitigate this nascent and growing threat to primary forests,” the researchers write.
