- This part contains Environment and science technology related current affairs from May-2016.
Clean Energy Related
Energy: Solar cooperative farms
Solar Cooperative in Kheda District, Gujarat
- SPICE: Solar Pump irrigator cooperative enterprise
- Farmers in Dhundi village of Kheda district of Gujarat, have started SPICE- solar cooperative, wherein they install solar irrigation pump in their farm with state government subsidy.
- Excess electricity is sold off to Madhya Gujarat Vij Ltd. For Rs. 4.63 /unit. For 25 years’ contract.
- Company can also sell off renewable energy certificates (REC) based on this purchase.
- A farmer with 1 ht. land can hope to earn Rs.60,000/- per year from selling excess solar electricity.
- Farmer can also cultivate cash crops like spinach, carrot, garlic, beet and medicinal plants in the shadow below the solar panels. Thus optimal landuse.
Energy: Hydel
| Arunanchal Hydropower |
- 2008: National Hydro power policy 2008: Arunanchal has ~50,000 out of ~1.5 lakh MW total hydropower potential of India.
- 2015: Dibang Multi purpose project (2880MW): India’s largest hydropower project – it was given clearance by government of India in 2015.
- May 2016: Anti-dam protests in Tawang. A Buddhist monk died in Police firing.
|
| Athirapally Hydel project |

|
Energy Misc. developments in May 2016

- LED bulb to be sold @ concessional rate of Rs.80 (household) and Rs.90 (Commercial purpose).
|
| Energy Bank |

| Pachai Tamizhagam |
- Meaning “Green Tamilnadu“. This is the ‘first’ Green party of TN, floated by one of the anti-nuke protestors.
- Their Election symbol is “Pot”.
|
Agriculture and Food
Bread Carcinogens
- Potassium bromate (KBrO3):- oxidizing agent, used in flour treatment to make bread white, fluffy, soft and elastic. Causes cancer.
- Potassium iodate (KIO3):– flour treatment agent, causes thyroid disorders.
- Many 1st world countries prohibit use of these chemicals in bread.
- But Centre for science and environment (CSE) has found these chemicals in major bread/pizza/burger brands of India.
Wheat Blast- Bangladeshi worry, Indian neednot
- Fungal disease originated from Brazil. It affects heads of the wheat stalk, and difficult to be treated by fungicides.
- Widespread in Bangladesh after they imported wheat seeds from Brazil without proper quality check.
- Bangladesh Government advised farmers to burn down the crop, and not to sow seeds from infected plots.
- India need not worry since our wheat harvest season mostly over, so less chances of disease spread.
Misc. developments in May-2016
| Gaushala meet |
- National conference on “Gaushalas” (Cowsheds), organized jointly by Agriculture and Environment ministries at Delhi’s Vigyan Bhawan.
|
| GM compulsory licensing |
- Earlier government had notified that GM-technology Licensor can’t refuse license to any seed company to use its technology in their hybrid varieties.
- GM Tech-Companies opposed this notification, and just like EPFO fiasco, here too government withdrew the notification.
|
Flora Fauna
| Black necked crane |
- Black necked cranes are considered to be embodiment of 6th Dalai Lama.
- Nyamjang Chhu river in Tawan region of Arunanchal is one of their Wintering site.
- NGT ordered government to conduct a study here on impact of hydel project.
|

|
| Man eater lions |
- Lions have now settled in Junagadh, Gir Somnath, Amreli and Bhavnagar districts of Saurashtra region of Gujarat. According to the 2015 census, there are 523 lions in the region.

- Forest department has encaged ~13 lions.
|

|
| Wasp |
- Scientists found a new species of wasp (Conobregma bradpitti) and named it after Hollywood actor Brad Pitt.
|
Marine Biodiversity
El-Nino & Coral Bleaching
- New study says El Nino→ hot water→ more stress on corals, ultimately they become white and vulnerable to diseases. 30% of Great barrier reef’s coral destroyed by Coral bleaching.
- Corollary to that, Hurricane/storms → cold water → less stress on corals
- For more about Coral bleaching- watch Rajtanil’s lecture G5/P2
Palau Jellyfish Lake
- It’s a group of islands in W.Pacific ocean. They’re part of UNESCO world heritage site.
- Earlier tourist attraction for “Jellyfish lake” for presence of Golden jellyfish which don’t sting, so you can swim without worry.
- But suddenly all jellyfish gone! Researcher blame it to climate change → Less rain → lake became more salty → uninhabitable for this particular species of jellyfish.
Wetland draft rules
- Government has sought public comments on new draft rules 2016 for Wetland conversation. They’ll replace 2010’s old rules.
- India has 26 of the total 169 Ramsar wetland sites. Ramsar agreement was signed in 1971 in Iran’s Ramsar.
- Notable wetlands in India: Wular Lake-Jammu Kashmir, Ashtamudi- Kerala, Deepor Beel- Assam and Nal Sarovar- Gujarat.
- More you can read in Indianexpress Q&A series (although as such no point, because these are still ‘draft’ rule. After they’re officially publish, you should worry.)
Earth, Climate Change, Disasters
| Earth wobbling |

Science Technology
Resuable space shuttle (RSV)
Image taken from Indianexpress
- To launch a satellite Payload, we need a “Launch vehicle”.
- Two major types of Launch Vehicles are PSLV and GSLV. Read my old notes for more on them
- But these launch vehicles get burnt on re-entry into the atmosphere.
- So, to minimize the cost and increase the frequency of launches, ISRO came up with idea of Reusable launch vehicle and conducted a technology demonstration in 2016, May.
- Criticism: its R&D and mfg. cost is far exceeding the cost of existing non-reusable launch vehicles.
Atomic Force Microscope
- Electron microscopes use electron beams to illuminate object for observation.
- Atomic Force Microscopes use sharp needle with dimensions of few nanometers. This needle ‘feels’ the geometry of the object and creates its picture.
- Problem: needles have to be replaced frequently.
Misc. terms: 2016, May from newspapers
