Experts urge collaboration for climate resilient agriculture in India
The policy silos need to be dismantled to ensure a climate-resilient agriculture ecosystem for the country, they said while speaking at a seminar regional policy dialogue on climate and agriculture — organised by a voluntary organisation, Sustainability Matters.
These participants included farm activists, scientists, and even farmers. The former Director of the Central Institute of Cotton Research (CICR), CD Mayee, said climate change is a reality that needs to be responded to. He called for technology adaptation on a large scale.
CICR's current Director, WN Wahmare, said Vidarbha is already experiencing a shift in rainfall patterns. Over 1,000 mm of precipitation has been recorded in areas where the average is 700 to 800 mm.
The former vice-chancellor of the Panjabrao Krishi Vidyapeeth, Sharad Nimbalkar, said soil health should be central to any strategy on dealing with climate change. "We are losing organic content at an alarming rate, and it is directly impacting the yields," he said.
"Universities and research institutions must lead in developing watershed-based models to generate soil sustainability."
The district superitendent (agriculture) Ravindra Manohare said Maharasthra's project on climate resilient agriculture (POCRA) project covers of 7,000 villages and is supported by a world bank fund of Rs6,000 crore. The seminar was part of the national series said a press note.

Leafhopper outbreak threatens cotton crop in North India: SABC
Bathinda: South Asia Biotechnology Centre (SABC), a scientific organisation, has flagged infestation of green leafhoppers (jassid), commonly known as "hara tela" on cotton across major cotton-growing districts of Punjab, Haryana and Rajasthan. The infestation has impacted Mansa, Bathinda, Fazilka in Punjab; Hisar, Fatehabad, Sirsa in Haryana and Hanumangarh, Sri Ganganagar in Rajasthan. SABC observed the outbreak during a field survey conducted under Project Bandhan by the Jodhpur-based centre, which has its research and development wing in Sirsa. The field team led by Dilip Monga, Bhagirath Choudhary, Naresh, Deepak Jakhar and K S Bhardwaj reported infestation levels of 12 to 15 leafhoppers per leaf, significantly above the economic threshold level (ETL). The field survey also reported cotton leaf injuries exceeding ETL based on the damage grading system. For the past three consecutive weeks, green leafhopper (jassid) populations have exceeded ETL, triggering yellowing of leaf margins and downward curling, classic symptoms of a jassid attack. The outbreak is being attributed to a confluence of weather conditions, including above average rainfall, an increased number of rainy days, persistent humidity and cloud cover, all of which have created ideal conditions for jassid proliferation. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Patna: 1 Trick to Reduce Belly Fat?

"The leafhopper infestation has emerged at a time when overall conditions are significantly better than the past three to four years. The crop appears to be robust across the northern region, except in late-sown areas of Sri Ganganagar, where irrigation was unavailable during the sowing period", said Bhagirath Choudhary, director, South Asia Biotechnology Centre's high-tech R&D station, Sirsa. Amrasca biguttula biguttula (Ishida) leafhopper is commonly referred to as an Indian cotton jassid or "hara tela". Leafhopper adults are very active, pale green in colour, measuring about 3.5mm in length, with two distinct black spots on forewings and vertex. They are readily identified by their characteristic diagonal movement on the leaves and are hence referred to as "leafhoppers". Population of leafhoppers occurs throughout the season but attains pest status during July-August. Up to 11 generations per season have been estimated to occur on cotton. Both nymphs and adults of leafhoppers suck the cell sap from cotton tissue and inject toxin, causing "hopper burn" symptom, characterised by yellowing, browning, and drying of leaves. The affected leaves show crinkling and curling symptoms. In extreme situations, there is reduced photosynthetic activity, browning and drying of leaves that can considerably hamper productivity of the cotton, and yield losses of up to 30%, if left unmanaged. PAU scientist Paramjit Singh said that there was no cause for alarm as the leafhopper was only a little above ETL. However, the survey team noted that failure to control the green leafhopper infestation promptly could lead to damage to the cotton crop in the coming days. Farmers must remain alert and take immediate action to manage the pest effectively to avoid potential yield losses. SABC has urged cotton farmers to adopt science-backed measures to effectively manage and control the growing menace of green leafhoppers (jassids). Such measures include regular field monitoring, accurate pest identification and assessment of infestation severity. Recommendations include use of neem-based bio-insecticides or other eco-friendly, organic pesticides to manage mild infestations and spray during early morning or late evening, when the wind is calm. It is important to ensure thorough coverage, especially on the underside of leaves, where pests usually hide. Farmers must also eliminate weeds within the field and along borders, since they serve as alternative hosts for leafhoppers and other pests.

New light on a powerhouse
My mother was very possessive and finicky about her kitchen; she always left it sparkling clean and locked it at night before going to bed, perhaps to prevent unauthorised access to leftover ice-cream in the refrigerator. A year after my marriage, she handed over the kitchen keys to my wife. 'It is now for you,' she said. By then, she was convinced that my wife understood the harms of night-time coffee and took it seriously. The kitchen continues to be securely locked at night, with the access code unavailable. By the time of the handover, the tremor in mom's hands was becoming more difficult to hide, her drooling speech more obvious. In the next six months, she needed help to walk, and by the year-end, she was confined to bed and unable to recall my name. A rapidly progressive type of Parkinson's disease was eating up my mom's brain from the inside. She died on July 1, 2010, Doctor's Day. Some 1.5 billion years ago, a free-floating single unicellular anaerobic organism (a single-cell life form that lived out of fermented product, not oxygen) accidentally engulfed a passing-by aerobic (oxygen-living) bacterium. For some unusual reasons, the 'gentleman' organism did not kill or digest the bacterium, and instead, let it live and thrive inside its cytoplasm. The thankful bacterium continued to produce nutrients using oxygen and supplied it to the organism in return for a safe habitat. This endosymbiosis turned the bacterium into a modern-day 'mitochondrium'. The mitochondrium is the powerhouse (the kitchen) of the cell. It produces ATP (energy) by taking in nutrients and oxygen. It also carries its own 37-gene DNA that gives it a degree of autonomy. Interestingly, the mitochondrial DNA comes entirely from the mother. This acquisition of mitochondria is the biggest evolutionary jump in the development of complex multicellular life. New research indicates that mitochondria are not just a 'battery pack', but a cellular motherboard. Dopamine deficit Parkinson's disease is a neurodegenerative disease thought to be the result of a reduction of a neurotransmitter called dopamine in specific areas of the brain. Present-day treatment aims at increasing the amount of dopamine while treating associated disabilities. New research now points to a possible defect in the mitochondria. The brain claims only 2% of our body weight but uses 20% of our total energy expenditure. This is the reason the energy-hungry brain neurons carry over 2 million mitochondria per cell (compared with hundreds in a liver cell, and thousands in a hard-working muscle cell). In an article and an interview published in Scientific American in May, researcher Martin Picard from Columbia University suggested that a defect in mitochondria might be a key driver of Parkinson's disease. Already, researchers have identified abnormal mitochondrial function in PINK1 and PRKN, two types of genetic Parkinson's disease. The disease has no known treatment. A recent update from the University of Michigan indicates that regular exercise, a diet rich in fruits and vegetables, and reduction of mental stress can contribute to its prevention. Early treatment of hypertension, diabetes and lipids helps. Interestingly, caffeinated drinks (coffee) seem to be beneficial too. The cellular kitchen (aka mitochondria) turns out to be so much more than a powerhouse; it is an HQ where ideas evolve, and plans are drawn and strategies laid out. The mitochondrial gene passed from mother to childen ensures that the coffee-addict father or the ice-cream crazy child has to obey the rules, both at home and in biology. The mitochondria seem to have a profound effect on cellular function and survival. Mitochondria-directed therapy might be the key to hitherto non-curable neurodegenerative and cardiovascular diseases. But our present kitchen admin is yet to be convinced about the protective effects of coffee. Our kitchen continues to be locked at night. tinynair@

Leafhopper outbreak threatens cotton crop in region
1 2 Bathinda: The South Asia Biotechnology Centre, a scientific organisation, has revealed an infestation of green leafhoppers (jassid), commonly known as 'hara tela', on cotton across major cotton-growing districts of Punjab, Haryana, and Rajasthan. The impact is notable in Mansa, Bathinda, and Fazilka in Punjab, Hisar, Fatehabad, and Sirsa in Haryana, and Hanumangarh and Sri Ganganagar in Rajasthan.

Leafhopper ≥5 plants showing damage grade II/III/IV, grade II shows minor crinkling, curling, and yellowing in lower leaves, grade III is observed with leaf crinkling, curling, and crinkling across the plant; stunted growth, grade IV with severe bronzing, crinkling, curling, and drying of leaves. If ≥5 plants per 20 sampled show grade II or above damage, immediate action is necessary, said Research Scientist Deepak Jakhar.
