DRP News Bulletin 3 Sept 2018: CHINA HAS STARTED DECOMMISSIONING DAMS

In a mountain village in southwest China’s Sichuan province, authorities have demolished seven small dam projects this year along a river to clear illegal developments in a new nature reserve. The demolition is part of a nationwide programme to close hundreds of tiny and often ramshackle dams and turbines and bring order to China’s massive hydropower sector after years of unconstrained construction.

The dams sat on an unnamed tributary of the fierce and flood-prone Dadu river, which feeds into the Yangtze, Asia’s largest and longest river, where the government says the “irregular development” of thousands of small hydropower projects has wrecked the ecology. But green groups say the campaign will not necessarily save the environment because it will not affect big state hydropower stations, which they say have caused the most damage.

On the 48 km Zhougong, authorities have already demolished small projects built in nature reserves or encroaching upon new “ecological red lines” drawn up to shield a quarter of China’s territory from development.

The government says small dams have disrupted the habitats and breeding patterns of many rare species of fish, although green groups argue the damage wrought by bigger dams is more severe, with entire towns and ecosystems submerged in water, which they say increases the risk of earthquakes, landslides and even climate change.

The mirage of normal monsoon

According to IMD, India is having normal monsoon this year, so far, as per rainfall till date (Sept 1, 2018). Against normal rainfall of 721.1 mm, India has received 676.6 mm rainfall, which is 6.2% below normal, considered within normal rainfall definition as per IMD. So India is having normal monsoon rainfall, says IMD. Let us check this against some ground realities.

However, East and North East India, one of the four regions for which IMD provides rainfall data, has so far had 27% below normal rainfall, while South India had 9% surplus rainfall.  Thus, while at all India level, what seems all normal, is average of different, though serious departures from normal rainfall. Let us say this is first level of mirage of normal rainfall. Continue reading “The mirage of normal monsoon”
