  • Turtle rehab centre in Bhagalpur, Bihar

    A first-of-its-kind rehabilitation centre for freshwater turtles will be inaugurated in Bihar’s Bhagalpur forest division in January 2020.

    About the rehab centre

    • The centre, spread over half a hectare, will be able to shelter 500 turtles at a time.
    • Earlier, rescued turtles were released into rivers without much treatment in the absence of any facility.
    • In the rehab centre they will be properly monitored before being released in their natural habitat.

    Why need such centre?

    • The need to build such a centre was felt after several turtles were found severely wounded and sick when rescued from smuggles by rescue teams.
    • This centre will play a significant role in treating these animals and their proper upkeep before being returned to their natural habitat.

    Why Bhagalpur?

    • Eastern Bihar has been an ideal breeding ground for turtles.
    • In Bhagalpur, the flow of water in the Ganga is ample. Also, there are many sandbanks in the middle of the river, which are ideal breeding ground for turtles.

    Significance of turtles

    • According to environmentalists, the turtles play a significant role in the river by scavenging dead organic materials and diseased fish.
    • They control fish population by their predation and control aquatic plants and weeds.
    • They are also described as indicators of healthy aquatic ecosystems.

    Various threats

    • According to a recent study conducted by Traffic India, around 11,000 turtles are being smuggled in India every year. In the past 10 years, as many as 110,000 turtles have been traded.
    • These species are now under severe threats due to habitat fragmentation and loss through dams and barrages, pollution, illegal poaching, accidental drowning through fishing nets and threats to their nesting habitats etc.
    • The turtles have come under serious threat primarily for two reasons — food and the flourishing pet trade.
    • Turtles are being frequently targeted for meat due to the prevailing belief that it gives an energy boost and keeps various diseases away.

    Back2Basics

    Operation Save Kurma

    • It is a periodic species specific operation on turtles conducted by Wildlife Crimes Control Bureau since 2017.
    • Under this, a total of 15,739 live turtles were recovered from 45 suspects, having inter-state linkages.
    • It helped the enforcement agencies to focus on the existing trade routes and major trade hubs in the country, which will be continued in future.
  • Species in news: Senna spectabilis


    The Kerala Forest Department is planning to adopt steps to arrest the rampant growth of invasive plants, especially Senna spectabilis, in the forest areas of the Nilgiri Biosphere Reserve (NBR).

    Senna spectabilis

    • The Senna spectabilis species was planted as avenue trees in Wayanad. The vayal ecosystem (marshy land) of the forest area now has this plant in large numbers.
    • The spread is posing a major threat to the forest areas of the reserve, owing to its quick growth and coppicing character.
    • The tree species was found in nearly 10 sq km area of the 344.44 sq km sanctuary around five years ago.
    • The plant has started to invade the adjacent Bandipur and Nagarhole tiger reserves in Karnataka and the Mudumalai tiger reserve in Tamil Nadu.
    • Now, it had invaded to more than 50 sq km of the sanctuary Wayanad WLS.
    • A recent study of the Ferns Nature Conservation Society recorded the presence of the plant in 78.91 sq km area of the sanctuary.

    Impact

    • An adult tree grows up to 15 to 20 metres in a short period of time and every year distributes thousands of seeds after gregarious flowering.
    • The thick foliage arrests the growth of other indigenous tree and grass species and causes food shortage for the wildlife population, especially herbivores.
    • Moreover, wildlife will not feed on the leaf of the treeas it is not palatable for them.
    • The allelochemicals produced by this plant adversely affect the germination and growth of the native species.
  • Forest Conservation Efforts – NFP, Western Ghats, etc.

    The environment ministry came out with a draft National Forest Policy (NFP). The policy has been prepared by the Bhopal-based Indian Institute of Forest Management (IIFM) and is aimed at facilitating ecologically responsible behaviour among stakeholders.

    source

    The proposed NFP is going to be third such document after India’s independence with first in 1952 followed by the second in 1988.


    Why is there a need for Forest Policy?

    • Forests and trees constitute nearly one fourth of the geographic area of the country.
    • Protection of this vast and valuable resource, improving and increasing the forest and tree cover requires adequate investment keeping in view the pressures on these forests, and the ecosystem services that they provide to the nation.
    • Large tracts of forest area in the country have degraded due to immense biotic pressure and lack of adequate investment.
    • The crux of the problem in India’s existing forest policy — the Forest Policy of 1988 — has been that it made the forest department the manager of the forests and the people lost their rights over it.
    • But as the Uttarakhand forest fires showed recently, a few hundred forest officials and a few thousand employees of the department can do nothing when a calamity strikes. They need community support in such emergencies.

    Key highlights

    • Less forest on hilly areas: Although the policy continues with the national goal of maintaining a minimum of one-third of the geographical area under forest or tree cover, Hills and mountainous regions may not be required to maintain two-thirds of the geographical area under forest cover.
    • Board to monitor management of forests: The policy states that a National Board of Forestry and State Boards of Forestry are to be established to ensure monitoring of the spread of the forest areas and management of forest cover.
    • Technology to minimize damage to forests: The policy states that forest land diversion projects related to mining, quarrying, construction of dams, roads and other linear infrastructure need to adopt special caution. Use of state-of-the-art technology which causes minimum pollution and damage should be promoted.
    • Green tax on citizens: The draft National Forest Policy (NFP) proposes the levy of a green tax for facilitating ecologically responsible behaviour and supplementing financial resources essential to address forestry woes.
    • Undermines FRA 2006: NFP ignores Forests Rights Act, 2006, which empowers local gram panchayats, especially in tribal areas close to India’s forests, and proposes a joint forest management-like mechanism to enhance agro-forestry.
    • New Mission: The policy proposes to launch a new Community Forest Management Mission, bringing government, community and private land under the new proposed management system.
    • Provisions for responsible tourism: It calls for developing “sound ecotourism models” with the focus on conservation while supplementing the livelihood needs of local communities.
    • Climate change to emerge as important factor in policy: It states that Climate change concerns should be effectively factored into all the forest and wildlife areas management plans and community ecosystem management plans.
    • Purchase of wildlife corridors: The draft policy indicates that CAMPA funds from diversion of forest land by industry are to be used for purchasing wildlife corridors from people.
    • Maintaining Urban forest: The policy also asks for management plans for city forests, parks, garden and woodlands to nurture and sustain urban health, clean air and related benefits.
    • Supports the Government Vermin Policy: In a nod to the Union government’s controversial decision to declare certain animals as “vermin” and implicitly sanctioning the slaughter of nilgai, wild pigs and monkeys in certain States, the forest policy recommends mitigating human-wildlife conflicts by taking up habitat enrichment, providing adequate and timely compensation in case of injury or loss of human life, property, crop damage or livestock casualties and developing teams of well-equipped and trained forest personnel.

    Significance of the policy

    • The policy recommendation for the launch of a national forest streams revival programme in a mission mode to tackle intensifying water crisis in India in the last few decades is a good step.
    • The levy of a green tax for facilitating ecologically responsible behaviour, supplementing financial resources essential to address forestry woes will act as a step to mitigate the effects of pollution.
    • Besides specifying how to manage forests, the draft policy said, “Other ecosystems such as alpine meadows, grasslands, deserts, marine and coastal areas should be protected and managed as well” and this will help to make it comprehensive.
    • It calls for developing sound ecotourism models with the focus on conservation while supplementing the livelihood needs of local communities which is a commendable move.

    Criticism of the policy

    • NFP ignores Forests Rights Act, 2006, which empowers local gram panchayats, especially in tribal areas close to India’s forests, and proposes a joint forest management-like mechanism to enhance agro-forestry. This move will bring back the forest department as the final authority over using forest resources instead of forest dwellers and communities dependent on them.

    Way forward

    • After facing much criticism from the Civil society the centre has withdrawn the draft policy recently. The criticism is not misplaced as the draft policy proposes to dilute the Forests Rights Act (FRA), do away with requirement of having two-third geographical area of mountainous and hill regions under forests, and for allowing industry to have commercial plantations on the forest land , increase the power of the forest bureaucracy and keep local communities out of the decision-making process.
    • While devising a new policy, the ministry must not only focus on increasing the forest area and bettering the quality of the forests but also ensure that the connection between forest-dependent communities and forests is not lost.

  • Monsoon Updates

    How does El Nino affect Indian Monsoon? A Comprehensive Explainer

    As many reports speculated that El Nino is the main cause of the worsening Indian Monsoon and has played badly with Indian agriculture, we thought that we should take a big picture of El Nino and it’s scope in India.


     

    • The Monsoon is basically a result of the flow of moisture laden winds because of the variation of temperature across the Indian Ocean.
    • There are a number of climatic phenomena which affect it namely the El nino, La nina etc.
    • We will look at their origin, impact and way forward.

    Now, let’s take a overview and develop our understanding. 

    What happens in a Normal Year?

    • Peru Current = Humboldt Current = Cold Current.
    • During normal year 2 things are very strong – Cold Peru Current and Trade Winds.
    • As a result, cold water is dragged from Peru towards Australia.

    What would be the result of this exchange?

    • Warm water region around Australia is called Western Pacific Pool (WPP).
    • WPP = low pressure = warm air ascends = cloud formation = rain over North Australia
    • This air also joins walker cell and begins descending near Peru.
    • Descending air = anti-cyclonic condition = high pressure = stability = no cloud/rain = Drought in Atacama Desert.

    (Simply, Walker cell is the result of a difference in surface pressure and temperature over the western and eastern tropical Pacific Ocean)

    What happens below the water from Peru to Australia ?

    At Peru coast, cold water upwelling brings nutrient to surface + more lunch for Plankton + more fishes = Peru fishermen gets happy.

    What happens above the water from Australia towards Peru?

    Warm water + low atmospheric pressure = good rainfall over Australia & Indonesia.

    What happens in La Nina Year?

    Same things as in a “normal” year, but 2 things become even “stronger” –

    • Cold Peru Current
    • Trade Winds

    What’s the Result?

    • Too many fishes at Peru coast = oversupply of fishes = prices become dirt cheap.
    • Too much rain / flood over Australia and Indonesia.

    This is what happens in normal and La Nino year, Let’s back to El Nino!


     


     

    What happens in an El Nino year?

    Two things become weak.

    • Cold Peru Current
    • Trade Winds
    • As result, cold water is not dragged from Peru to Australia.
    • But reverse happens, warm water is dragged from Australia towards Peru.
    • Consequently, warm water + low pressure condition develops in the Eastern Pacific (Peru) and Cold condition + high pressure in Western Pacific (Australia).

    What will happen if pressure is inversely related with amount of rainfall ?

    • Rain & Floods at Peru, Atacama and even Southern USA
    • Drought at Northern Australia, Indonesia- even bushfires.
    • Storms and Hurricanes in East Pacific.
    • Coral bleaching (high temperature coral dies)

    But, what is the El Nino?

    • El Nino is an Oceanic and Atmospheric phenomenon that leads to unusual warming of water in the Peru coast, occurs every 3-5 years.
    • Consequently, warm water + low pressure condition develops in the Eastern Pacific (Peru) and Cold condition + high pressure in Western Pacific (Australia).
    • Since Pressure is inversely related with amount of rainfall, El Nino causes drought situation in Australia and South East Asia.
    • It weakens the trade winds and changes in Southern Oscillation, thereby affects the rainfall pattern across the world.

    el-nino-phenomenon


    What is Southern Oscillation?

    • Alternating of (tropical) sea level pressure between the eastern and western hemispheres.
    • We can measure Southern Oscillation by observing the pressure difference between Tahiti (French Polynesia) and Darwin (Australia).

    How does El Nino affect Indian Monsoon?

    • El Nino-Southern Oscillation (ENSO) water circulation happens between Australia and Peru.
    • But, the wind movement is part of larger atmospheric circulation hence affects the rainfall over India. But, how?
    • We have learned that During normal year, the warm water moves towards Australia, this pool of warm water is called Western Pacific Pool (WPP).

    So, from WPP air rises above and moves towards two walker cells –

    • Towards Peru coast = this affects rainfall in South America.
    • Towards Mascarene High Pressure zone near East Africa. So, this affect Indian monsoon.

    Why should India worry about?

    • Drought condition decreases the agriculture output, leads to food inflation.
    • Declined supply of cotton, oilseeds and sugarcane negatively affects the textile, edible oil and food processing industries respectively.

    What is the way forward?

    Let’s discuss first Near-term Solutions?

    • Government must expand farm insurance cover and advice financial institutions to settle crop insurance claims in the drought-hit areas without delay. Otherwise, it results in farmer suicides (e.g. Maharashtra farmers’ suicide ).
    • High quality seeds of alternative crops must be distributed among farmers in drought-affected areas.
    • Need of realistic assessment of ground level situation in order to estimate the shortfall of oilseeds and pulses and help traders with market intelligence.
    • Scrapping the APMC Act and allowing free flow of agricultural goods among the states.
    • This would help bridge the mismatch of demand and supply of goods, which is the underlying factor contributing inflation.

    What should be the Long-term Solutions?

    • Developing drought free crop varieties and distributing its subsidized seeds to the farmers. It is a part of National Action plan on climate change in Agriculture.
    • Using low water use technologies like drip and sprinkler irrigation.
    • The MSP regime in India has to provide more remuneration for less water consuming crops.
    • Strengthening community watershed management and development by protecting and conserving local water sources like ponds, lakes etc.
    • Developing early warning systems and alerting the farmers much in advance like recently launched Kisan SMS scheme.
