After days of intense coverage of the landslides in Wayanad, the news cycle has moved on to other calamities. But the problems remain, and things cannot be left to benign neglect as is usually the case. For example there was a strange thundering noise from deep underground that alarmed people in the area. This is ominous, as it may presage a tectonic movement, although there have been no big quakes here for centuries. A dramatic before-and-after report from Reuters, using satellite images from Planet Labs, Google, Maxar Technologies and Airbus, shows how the landslide left a giant scar on the surface of the earth, washing away hundreds of houses, leading to widespread fatalities and destruction. Prime Minister Modi visited the afflicted area. Better governance, both by Center and State, is sorely needed to tackle the problem, because it is not simple: there are proximate, preponderant and root causes. A lot of it is anthropogenic based on local factors, but climate change is also a major factor, as the local climate and rainfall patterns have shifted dramatically in the recent past. There was a drought in 2015, followed by the Ockhi cyclone in 2017, and then landslides and floods in 2018 and 2019. As a resident of Kerala, who has visited Wayanad only twice (once in 2018 and the second time in April this year), both the problems and the possible solutions are of immediate importance to me, because the very same issues are likely to crop up all over the State, and unless remedial measures are taken now, we can expect further tragedies and endless suffering.  Proximate Cause: Excess Rain The proximate cause is La Nina-enhanced rainfall, which has been higher this year along the west coast. In Wayanad itself, it rained 572mm in 48 hours before the landslide: about 1.8 feet, an enormous amount.  Before the Wayanad landslide, there had been another in Shirur on the Karnataka coast near Ankola, where a number of people were swept away. The story of Arjun, a Kerala trucker whose truck full of lumber disappeared, was all over the news, and after a weeks-long search, there was no sign of him or the truck.  The total rainfall since June 1 was of the order of 3000mm in Wayanad, which is unusually high, creating vulnerability to landslides. In a recent interview, environmental expert Madhav Gadgil mentioned that quarrying may have added to the intensity of the rainfall, because the fine dust from the mining and explosions forms aerosols, on which water molecules condense, leading to excessive precipitation.  The intense rainfall saturated the soil, and in the absence of sufficient old-growth vegetation that might have held it together, the hillside simply collapsed.  Preponderant Cause: Population Pressure, Over-Tourism, Ecocide The preponderant causes of the problems in Wayanad are obvious: population pressure, over-tourism and environmental destruction. The forest has basically ceased to exist due to human exploitation. According to India Today, 62% of the green cover in the district disappeared between 1950 and 2018 while plantation cover rose by around 1,800%. Fully 85% of the total area of Wayanad was under forest cover until the 1950s. Overpopulation, settlement and habitat loss My first visit to Wayanad was in 2018, when we drove to Kerala from Karnataka: from the Nagarhole/Bandipur Wildlife Sanctuaries to the contiguous Wayanad Wildlife Sanctuary, all forming a Project Tiger ecosphere along with neighboring Mudumalai Wildlife Sanctuary in Tamil Nadu. Together they form the Nilgiri Biosphere Reserve.  Bandipur/Nagarhole actually looks like a forest. But I was astonished when we drove into Wayanad, because it does not look like a forest any more: it is full
