Paddy farming in times of climate change – field notes – A sequel
Guest Article by Dr. Sreeja KG and Dr. Madhusoodhanan CG
Climate change and its impacts in the tropics are changing the once familiar landscapes, once certain weather patterns, once secure living spaces beyond recognition. The disasters that can be as local as a tidal surge to national level episodes of cyclones, wildfires and massive floods are being managed in the same administrative mode as has been the practice during the more forgiving past: without training, without relevant real time information, without involvement of the communities and often merely with the strong will and dedication of the field staff and local volunteers. With events far in between, episodic and with time to recoup, we have been spared total and irrevocable breakdown of the system and society. But for how long?

Kerala and Uttarakhand floods in Oct 2021: Did the forewarnings help?
The October 2021 flood disasters in two ends of India, in Kerala and Uttarakhand have a lot common. Both happened after the end of normal dates of South West Monsoon 2021. In both cases it is repeat of earlier such disasters in respective states. In both cases, there were reports by expert reports warning about the disasters. In both cases the rainfall events were broadly along the lines warned by the climate scientists, but in both cases the state was ill prepared to cope with it. In both cases, inappropriate human interventions have worsened the disasters in major ways. And in both cases disaster management seems to be absent from ground. In both cases, more precise forecasts about the rainfall quantum and location would have helped. (Feature Image above is from The Hindustan Times, Oct 23, 2021)

(Feature image: Sindh river seen from Duderhama bridge. Source Wikipedia.)
In a noteworthy development this week, on Oct 21, 2021, the Jammu & Kashmir High Court bench of Chief Justice Pankaj Mithal and Jutice Sanjay Dhar has sought reports about the Sindh River from Secretaty Revenue and Seccretary Irrigation & flood control by Nov 15, and both officers have been directed to be present in the court. The HC has been following up on this issue through earlier orders on Sept 18, Aug 12. The High Court has been asking for demarcation of Sindh River in Ganderbal district of J&K and removal of encroachments.
The River originates in the Machoi Glacier at an elevation of 4800m east of the Amarnath temple and south of the Zoji La and passes through the alpine hill station Sonmarg. The river is facing the worst kind of pollution through constructions- hotels, tourist hut, resorts etc – being undertaken at various places on the river beds and floodplains. The River is the natural habitat of trout, and other fish, the most famous among them are: brown trout, rainbow trout, snow trout, Shuddgurn and Anyour. The River also suffers from mechanised mining and pollution.

DRP News Bulletin 11 Oct 2021: Are we being forced towards nature based solutions?
Four interesting developments in this week seems to suggest that mankind is being pushed closer to nature based solutions to society’s needs. In Brussels in Belgium (Europe), the local government has started to uncover the Senne river that now is hidden under the pavements with the declared objective to “return nature to the city” and the river becoming an ecological corridor in the city.
In USA, the Army Corps of Engineers, more known as Dam builders, have over the last five years, moved towards nature based flood control by creating wetlands. In the 2020 Water Resources Development Act, US Congress directed the Corps to consider nature-based systems on equal footing with more traditional infrastructure. Its possibly a baby step, but a very significant one for a traditional dam building organisation that has stopped building dams and have been working towards decommissioning dams.
