A non-profit warns EPA against expanding the use of oxyteracycline as pesticide (downtoearth)

On May 10, the Center for Biological Diversity along with Johns Hopkins Center for a Livable Future sent their comments to the Environmental Protection Agency (EPA), asking the regulatory agency to not expand the use of a medically important antibiotic for citrus crops.

A US crop protection company, Nufarm Americas Inc., had sought registration of an antibiotic, oxyteracycline, for use in citrus crops and in dried citrus pulp from the EPA. The agency called for comments from the public by May 10.

The Centre said in its press release that Nufarm Americas Inc. has already been permitted emergency exemption to use the antibiotic in Mycoshield to treat citrus greening disease in Florida starting January 2017 till end of the year. The release added that exposure to antibiotics can have serious unintended side effects on wildlife, including adverse drug reactions, and can also cause changes in the chemical composition and pH of water and soil with potentially serious consequences.

“Since tens of thousands of people are dying every year as a result of antibiotic-resistant infections, it’s outrageous that the EPA is allowing, and may even expand, the use of antibiotics as pesticides,” said Hannah Connor, a senior attorney at the Center. “This is a careless, shortsighted practice that contributes to the reduced effectiveness of these drugs.”

Interestingly, dried citrus pulp is fed to cattle for beef production in the US. This is akin to cattle consuming antibiotics laden feed. The WHO recognises that the misuse of antibiotics in the production of food-producing animals also contributes to the spread and rise of antibiotic resistance.

Antibiotic resistance is a global health concern today. While resistance to antibiotics is a natural phenomenon, the misuse of antibiotics in agriculture is recognised as a factor which speeds the development of resistance in bacteria. The Center for Disease Control and Prevention estimates that more than 2 million people are infected with antibiotic-resistant organisms each year, leading to an estimated 23,000 deaths.

Khar’s experimentation with Himalayan nettle brings recognition (downtoearth)

Nature never fails to surprise us. In many parts of the world, natural resources are the only source of livelihood opportunities available to people. They can be in the form of wild shrubs like Daphne papyracea and Daphne bholua (paper plant) that are used to make paper or Gossypium spp (cotton) that forms the backbone of the textile industry.

Nothing can compete with the dynamism of biological resources. Recently, Girardinia diversifolia (Himalayan nettle), a fibre-yielding plant, has become an important livelihood option for people living in the remote mountainous villages of the Hindu Kush Himalaya.

There is a community in Khar, a hamlet in Darchula district in far-western Nepal, which produces fabrics from Himalayan nettle. The fabric and the things made from it are sold in local as well as national and international markets as high-end products.

A Himalayan nettle value chain development initiative implemented by the Kailash Sacred Landscape Conservation and Development Initiati…

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”.

The Supreme Court on Friday came close to ordering the government not to deport the Rohingya.

It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests.

The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach it in …

Cloud seeding

Water is essential for life on the earth. Precipitation from the skies is the only source for it. India and the rest of Asia are dependent on the monsoons for rains. While the South West Monsoon is the main source for India as a whole, Tamil Nadu and coastal areas of South Andhra Pradesh get the benefit of the North East Monsoon, which is just a less dependable beat on the reversal of the South West Monsoon winds.
