Sunderbans needs flow of sweet water for its survival: study

As climate change continues to impact socio-economic life of people in the Sunderbans, researchers have called for ensuring supply of fresh sweet water to the island along with other adaptation strategies for saving the mangrove tress, people and the unique biodiversity of the region.

 A study “The Sunderbans, impact of climate change on people’s livelihood: options for adaptation” — the result of a joint effort School of Oceanography Studies, Jadavpur  University  and Caritas India, a non government organisation —   released on Saturday suggests “ linking of canals to areas outside Sunderbans to ensure  inflow of sweet water  in the  interior connected  regions.”  Experts, who were present at the release of the study, also stressed on the need of providing vocational training to the youth in Sunderbans that would help them sustain as climate change will eventually impact traditional livelihoods like farming and fishing.
Speaking at the launch of the report, Professor Sugata Hazra said that unless “we are able to save rivers and ensure fresh water supply to the areas of Sunderbans, it is difficult to save the people and the ecosystem from the effects of climate changes.”
  The key research outcomes of the report included a recommendation on diversion of water of river Hooghly through lock gates at Kulpi and  Karanjali to benefit five or six blocks.
6 blocks “vulnerable”
  One of the key findings of the report is that six of 19 blocks in the Sunderbans archipelago “are highly vulnerable from the perspective of fresh water availability” and that blocks with limited access to fresh water have lower percentage of agricultural land under second crop.
  On the necessary adaptation in agriculture the reports recommends “crop diversification,” establishing soil-testing facilities at block level and advice to farmers on ecosystem specific crop selection.  The study also presents case-studies of farmers from the Sunderbans having adopted the integrated land and water resource model in the wake of challenges related to monoculture and crop failure.   Participating in the discussion over the launch of the study, West Bengal Minister for Sunderbans Affairs Manturam Pakhira expressed concern that experts were warning that a portion of Sunderbans would go under water in the next few years.   An estimation of composite vulnerability of the islands of Sunderbans points out that Mousani and Ghoramara islands are highly vulnerable to climate change, the report states.

    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 …

    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…

    The Chipko movement as it stands today

    The idea behind the Chipko movement originated in early 1970s from Mandal, a village in Chamoli district of Uttarakhand. Forty-three years later, Down To Earth travelled to Chamoli and Tehri Garhwal and spoke to the participants of this movement about its relevance today
