  • [pib] Seaweeds Mission

    TIFAC has unveiled a Seaweed Mission for commercial farming of seaweeds and its processing for value addition.

    Note the species of edible seaweeds mentioned in the newscard.

    Seaweed Mission

     

    The Mission envisages the following activities:

    • establishing model demonstration farms over one hectare for the cultivation of economically important seaweeds in nearshore and onshore along the Indian coast
    • Kappaphycus all over Indian coast
    • Gracilaria dura in Gujarat
    • Gracilariaverrucosa in Chilika Lake (Odisha)
    • Ulva Linza or Ulva prolife rain Chilika Lake (Odisha)
    • Ulva Lactuca or Ulva fasciata or Ulva indica all over India coast

    Proposed Sites: Gujarat / Tamil Nadu / Andhra Pradesh / Odisha / Karnataka

    Seaweed production in India

    • Out of the global seaweed production of ~ 32 million tons fresh weight valued around 12 billion US dollars. China produces ~57 %, Indonesia ~28% followed by South Korea.
    • India is having a mere share of ~0.01-0.02%.
    • Despite several advantages, commercial seaweeds cultivation has not been taken place in the country at an appropriate scale, as being practised in South-East Asian countries.
    • By an estimate, if cultivation is done in ≈10 million hectares or 5% of the EEZ area of India, it can provide employment to ~ 50 million people.
    • Seaweed cultivation also enhances ocean productivity, abates algal blooms and sequesters millions of tons CO2.

     

  • A resilient future for Uttarakhand

    The article discusses the factors that could explain the cause of the recent flash floods in Uttarakhand and suggest the immediate steps to deal with such disasters.

    What makes Uttarakhand vulnerable

    • Days after a glacier burst in the Chamoli district of Uttarakhand caused flash floods, the scientific community is still struggling to understand what triggered the disaster.
    • Uttarakhand is located in the midst of young and unstable mountains and is subject to intense rainfall.
    • For years experts have voiced their fears about an impending disaster due to climate change, rapid and indiscriminate construction activities, and the subsequent ecological destruction in the region.
    • Studies have shown that widespread settlements, farming, cattle grazing and other anthropogenic activities could destroy the natural barriers that control avalanches and floods, thereby enhancing the possibilities of a glacial lake outburst flood.
    • The Hindu Kush Himalaya Assessment Report (2019) had pointed out that one-third of the Hindu Kush Himalaya’s glaciers would melt by 2100 and potentially destabilise the river regime in Asia, even if all the countries in the region fulfilled their commitments under the Paris Agreement.

    Possible causes of the current glacial outburst

    • The current glacier burst was loosely attributed to erosion, a build-up of water pressure, an avalanche of snow or rocks, landslides or an earthquake under the ice.
    • A rock mass, weakened from years of freezing and thawing of snow, may have led to the creation of a weak zone and fractures leading to a collapse that resulted in flash floods.

    Issue of construction activity

    • Experts and activists have incessantly asked for scrutiny into the construction of hydroelectric power projects in Uttarakhand.
    • There have also been allegations about the use of explosives in the construction of dams and other infrastructure.
    • In 2014, an expert committee led by Dr Ravi Chopra, instituted to assess the role of dams in exacerbating floods, provided hard evidence on how haphazard construction of dams was causing irreversible damage to the region.

    7 Immediate steps

    • 1) Investing in resilience planning, especially in flood prevention and rapid response.
    • 2) Climate proofing the infrastructure such as by applying road stabilisation technologies for fragile road networks and strengthening existing structures like bridges, culverts and tunnels.
    • 3) Strengthening embankments with adequate scientific know-how
    • 4) Reassessing development of hydropower and other public infrastructure.
    • 5) Investing in robust monitoring and early warning system.
    • 6) Establishing implementable policies and regulatory guidelines to restrict detrimental human activities, including responsible eco- and religious tourism policies.
    • 7) Investing in training and capacity building to educate and empower local communities to prevent and manage risks effectively.

    Consider the question “What are the factors that make Uttarakhand vulnerable to natural disasters? Suggest the measures to prevent and deal with the disasters” 

    Conclusion

    India needs to urgently rise up to the challenge by applying innovative and inclusive solutions that support nature and marginalised communities, to restore and rebuild a resilient future for Uttarakhand.

  • Role of dams in Uttarakhand floods

    The article explains the link between the disasters in the Uttarakhand and the construction of dams.

    How dams exacerbate disasters

    • The use of explosives has repeatedly been questioned for dam construction, and the construction of other infrastructure projects, such as roads, in the fragile Himalayan State.
    • Other than this, deforestation takes place when dams are constructed.
    • The construction material that is supposed to be dumped on separate land is often dumped into the rivers.

    The Chopra Committee report after Kedarnath flood

    • The Chopra Committee report of 2014 brings more clarity on how dams exacerbate a disaster such as floods.
    • Its report mentions how dams exacerbated the 2013 deluge, mainly as riverbeds were already raised from the disposed muck at the dam construction sites.
    • The report presents evidence to prove that dams are not only damaged in floods, they also cause immense damage in downstream areas.
    • This is because as floodwaters damage a barrage, they increase the destructive capacity of the water that flows downstream of the barrage.
    • In an affidavit submitted on December 5, 2014 in the Supreme Court, the Union Ministry of Environment, Forest and Climate Change acknowledged the adverse impact of dams in the 2013 floods.

    Impact of climate change and threat of earthquakes

    • Himalayan glaciers are receding and disintegrating as a result of climate change, and the snow cover in the Himalayas is also thinning.
    • Research shows an increase in number and volume of glacial lakes as a result of of increased temperatures.
    • For dams, this means rapid increase or decrease in the reservoir water level.
    • It also means that the projections on the life of a dam reservoir may not stand due to erratic events, such as floods, that could rapidly fill a reservoir with muck and boulders brought along with the floods.
    • In terms of earthquake risk, Uttarakhand lies in Seismic Zone-IV (severe intensity) and Seismic Zone-V (very severe intensity).
    • Ignoring this, many dams have been constructed in zones that are under high risk of witnessing severe earthquakes.

    Consider the question “Examine the role played by the dams in exacerbating the disasters in the Himalayan states”

    Conclusion

    It is clear that dams worsen disasters, and for this to be ignored by the State authorities is unfortunate.

  • Flash floods and their mitigation

    This newscard is an excerpt from the original article published in the Indian Express.

    What are Flash floods?

    • A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and depressions.
    • It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields.

    Take a glimpse of the series of disasters in Uttarakhand

    Chamoli example

    • Flash flood incident in Uttarakhand is another warning of the dangers that a Himalayan state like Uttarakhand faces from natural processes like landslides, snow avalanches cloudbursts or lake bursts.
    • As we saw in 2013 in the same state, such processes can trigger much bigger disasters and cause massive destruction.
    • But it is possible to work towards minimising the threat of such incidents and reduce their impact.

    Role of glacial lakes

    • There are over 1,000 glaciers in Uttarakhand. Almost all of them are receding. Most of the glaciers also have debris cover.
    • When glaciers retreat due to rising temperatures, the snow melts but the debris remains. This debris aids in the formation of lakes.

    Cause: Retreat of glaciers

    • Glaciers have reduced considerably in mass and surface area since the little ice age period.
    • This has led to the formation of a large number of glacial lakes all across the Himalayas.
    • Many of these high-altitude lakes are potentially dangerous, because of their potential to cause flash floods in the event of a breach.

    How big is the threat?

    • Over the years, the frequency of formation of these lakes has increased.
    • But despite that, there are not many GLOF (glacial lake outburst flood) events happening in Uttarakhand.
    • Not as many as in Sikkim, for example. This is because Uttarakhand has very steep slopes, and the water manages to find a way out.

    What should be done?

    (a) Coherent research

    • There are a lot more glaciologists and others who are working in the area and generating data.
    • Multiple scientific groups and institutions are involved. But there is no coherent output. Lots of data are being generated but not being put to good use.
    • There has to be one agency dedicated to the job.

    (b) Monitoring

    • The first step in tackling the threat from these glacial lakes is to start monitoring them and the glaciers more actively and regularly.
    • There is a need to monitor every glacier. Glaciers in one basin do not have remarkably different properties.
    • Relying only on satellites and remote sensing is not going to be enough.
    • What is required is a consolidated state of glaciers in India, with the ability to zoom in on any of them and track the changes happening year by year.

    (c) Planning

    • Construction-related activities in the state might not have a direct link to Chamoli incident, but these are not entirely benign.
    • The Himalayas are very young mountain systems, and extremely fragile and a minor change in orientation of the rocks can be enough to trigger landslides.
    • It is important to include glaciers in any environment impact assessment for major projects such as the construction of dams.
    • The entire catchment areas should be made part of the impact assessment.

    (d) Mitigation

    • If we monitor the glaciers regularly, it would enable us to identify the lakes that need mitigation solutions.
    • Several structural and geotechnical measures can be applied, and there are successful examples where the threat from these lakes has been reduced.
    • It is possible to construct channels for the gradual and regulated discharge of water from these lakes, which will reduce the pressure on them, and minimise the chances of a breach.
    • At the same time, it also reduces the volume of water that goes into the flash flood. Also, alarm systems can be set up at the lakes that will warn the community downstream whenever an overflow happens.

    Way forward

    • It is not possible to completely prevent these kinds of incidents. But their potential to cause destruction can certainly be minimized.
    • Scientists can find a way to let the lake waters slowly drain at the nearby river at a regulated rate so that there is no flooding, and the pressure on the lake does not become unbearable.
    • Such solutions can be applied in Uttarakhand, and some work is being done.

  • Why hydel projects in the Himalayas are worrying?

    The flash flood that claimed several lives in Chamoli has caused Uttarakhand’s hydroelectric projects (HEPs) to be scrutinized closely.

    Q.How do hydropower projects pose geological and topographical threats to the ecosystem? (150W)

    Why Hydropower in Uttarakhand?

    • Uttarakhand has a tricky relationship with electricity.
    • With a landscape that’s inhospitable to thermal power grid lines and with people too poor to pay for electricity, micro and mini hydro-electric power projects were seen as the answer.
    • Between the government’s long-standing ‘power for all’ objective, and environmentalists pushing for a cleaner, renewable energy, setting up dozens of hydel power plants seemed ideal.

    Impacts of HEPs

    Limitless quarrying, deforestation, stopping the flow of rivers, and mushrooming of hydropower projects have made the Himalayas unstable.

    • Existing and under-construction hydro-power projects in Uttarakhand have led to several deleterious environmental impacts (Char Dham Committee).
    • Among the significant impacts are on the river ecosystem, forest and terrestrial biodiversity, geological environment and social infrastructure.
    • More than seven years later, some experts believe that over-exploitation of rivers and rampant damming for hydroelectric projects (HEPs) could be one of the big factors responsible for the Chamoli disaster.
    • The ‘river-bed profile’ across the major HEPs of Uttarakhand has changed significantly, suggesting the possibility of disasters in future.

    The Kedarnath floods

    • Between June 13 and 17, 2013, Uttarakhand had received an unusual amount of rainfall.
    • This led to the melting of the Chorabari glacier and the eruption of the Mandakini river.
    • The floods affected large parts of Uttarakhand, Himachal Pradesh and Western Nepal.
    • The heavy rainfall caused massive flash floods and landslides resulting in the death of residents and tourists as well as extensive damage to property.
    • Over 5,000 people were killed in the floods

    Construction still persists

    • Neglecting all warnings of the experts, rampant construction was carried out in the sensitive zones even after the 2013 Kedarnath deluge.
    • Notably, two dozen hydropower plants of Uttarakhand were rejected by the Supreme Court after the expert panel report.

    HEPs in Uttarakhand

    The rivers and basins in the state are dotted with 43 micro hydel projects. Some of them are:

    Alarms have been raised earlier

    • The Kedarnath expert committee had warned about the excessive exploitation of vulnerable regions and the need to re-study and re-evaluate the HEPs of Uttarakhand.
    • The report also objected to HEPs at an altitude of over 2000 metres.
    • The report pointed out that the potential threat of landslide, cloudburst, subsidence, flash floods has increased tremendously in the past few years and many critical zones need immediate attention.
    • The study also mentioned that a lot of anthropogenic pressure due to different activities related to HEPs was alarming and needed checks.

  • [pib] Scheme for Management of Crop Residues

    The Scheme on ‘Promotion of Agricultural Mechanization for In-Situ Management of Crop Residue in the States of Punjab, Haryana, Uttar Pradesh and NCT of Delhi’ has been extended for the year 2021-22.

    We can cite the example of this scheme for crop residue management as an effective solution against stubble burning.

    Management of Crop Residues

    • In pursuance this, a central sector scheme (100% funded by centre) was launched in 2018 Budget to support the efforts of the governments of Haryana, Punjab, Uttar Pradesh and the NCT of Delhi to address air pollution.
    • It aimed to subsidize the machinery required for in-situ management of crop residue.

    Various objectives of the scheme:

    • Protecting the environment from air pollution and preventing loss of nutrients and soil micro-organisms caused by burning of crop residue;
    • Promoting in-situ management of crop residue by retention and incorporation into the soil through the use of appropriate mechanization inputs and
    • Creating awareness among stakeholders for effective utilization and management of crop residue

    Outcomes of the scheme

    • The residue burning events in 2020 in Punjab, Haryana and UP together have reduced by -30% as compared to 2016.
    • In Punjab the reduction is -22.7%, Haryana – 63.8% and UP – 52.01%.

  • Glacial Lake Outburst Flood (GLOF) in Uttarakhand

    A massive glacier burst at Chamoli in Uttarakhand yet again bringing back our focus to the dangers of climate change.

    A wake-up call!

    Uttarakhand is often at the heart of various Himalayan disasters such as flash floods, cloud bursts, avalanches and earthquakes.

    The Chamoli incident signifies the dawn of ugly faces of climate disaster for which the mankind is clueless. At last, someone has to be blamed, isn’t it?

    What is the news?

    • Experts are uncertain about what caused the massive glacier burst at Chamoli in Uttarakhand.
    • It is unclear whether there was an avalanche in the area recently or whether the lake breach was the result of construction, anthropological activities, climate change etc.

    What is GLOF?

    • A GLOF is a type of outburst flood that occurs when the dam containing a glacial lake fails.
    • An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup.
    • The dam can consist of glacier ice or a terminal moraine.
    • Failure can happen due to various factors such as:
    1. Erosion, a buildup of water pressure
    2. Avalanche of rock or heavy snow
    3. Earthquake or volcanic eruptions under the ice or
    4. Displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it

    Possible causes for Chamoli

    Avalanche

    • An avalanche is falling masses of snow and ice which gathers pace as it comes down the slope.
    • But an avalanche is unlikely to result in the rise of water of that magnitude what Chamoli witnessed.

    Cloudburst

    • What happened in Uttarakhand in 2013 was a multi-day cloudburst.
    • It is a sudden, very heavy rainfall accompanies by a thunderstorm. But it generally happens in monsoon.
    • In fact, the season in which such a disaster was witnessed has surprised experts as there is no immediate trigger that can be pointed to as the reason why water level rose to that level washing away two hydro projects.

    Why always Uttarakhand?

    • Human activities profoundly affect the earth’s climate and mountains are a sensitive indicator of that effect.
    • The mountain ecosystem is easily disrupted by variations in climate owing to their altitude, slope and orientation to the sun.
    • As the earth heats up, mountains glaciers melt at unprecedented rates.
    • Several scientists believe that the change occurring in the mountain ecosystems may provide an early glimpse of what could come to pass in a lowland environment.

    Conclusion

    • The current policy of the government of pursuing hydro-power projects indiscriminately cannot be ignored.
    • The entire State of Uttarakhand is categorised as falling in Zone-IV and V of the earthquake risk map of India.
    • The potential of the cumulative effect of multiple such projects has turned out to be more environmentally damaging than sustainable.

  • [pib] India gets its first Centre for Wetland Conservation and Management

    The Ministry of Environment, Forest and Climate Change has announced the establishment of a Centre for Wetland Conservation and Management (CWCM).

    What are Wetlands?

    • A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.
    • The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.
    • Wetlands provide a wide range of important resources and ecosystem services such as food, water, fibre, groundwater recharge, water purification, flood moderation, erosion control and climate regulation.

    Ecological significance of wetlands

    • Wetlands provide a wide range of important resources and ecosystem services such as food, water, fibre, groundwater recharge, water purification, flood moderation, erosion control and climate regulation.
    • They are, in fact, a major source of water and our main supply of fresh water comes from an array of wetlands which help soak rainfall and recharge groundwater.
    • Just as forests are called the ‘lungs of the earth’, wetlands are the ‘kidneys’ that regulate water and filter waste from the landscape.

    About CWCM

    • WCM would serve as a knowledge hub and enable exchange between State/ UT Wetland Authorities, wetland users, managers, researchers, policy-makers and practitioners.
    • It would function as a part of the National Centre for Sustainable Coastal Management (NCSCM), Chennai.
    • It would address specific research needs and knowledge gaps and will aid in the application of integrated approaches for conservation, management and wise use of the wetlands.

    Why need such a centre?

    • India has nearly 4.6% of its land as wetlands, covering an area of 15.26 million hectares and has 42 sites designated as Wetlands of International Importance (Ramsar Sites), with a surface area of 1.08 million hectares.
    • The year 2021 also commemorates the 50th anniversary of the signing of the Ramsar Convention on Wetlands on 2 February 1971 in Ramsar, Iran, celebrated annually as World Wetlands Day.

    Back2Basics: Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

    Faunal Diversity in Ramsar Wetlands of India

  • The problem of ageing dams in India

    Ageing dams threaten India’s water security, affect farmers’ income and increases the frequency of flooding. 

    What is a dam?

    • A dam is a barrier that stops the flow of water and results in the creation of a reservoir. Dams are mainly built in order to produce electricity by using water. This form of electricity is known as hydroelectricity.
    • Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.

    Types of Dams

    There are many dams in India, and hence there is a need to know about them as there are questions based on the dams of India. The Bank Exams like IBPS or SBI contains questions from this section.

    Based on the structure the types of dams are as mentioned below:

    1. Arch Dam: An arch dam is a concrete dam that is curved upstream in the plan. It is designed so that the hydrostatic pressure (force of the water against it) presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses.
    2. Gravity Dam: Dams constructed from concrete or stone masonry are Gravity dams. They are designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. These are designed in such a way that each section of the dam is stable and independent of other section.
    3. Arch-Gravity Dam: This dam has the characteristics of both an arch dam and a gravity dam. It is a dam that curves upstream in a narrowing curve that directs most of the water pressure against the canyon rock walls. The inward compression of the dam by the water reduces the lateral (horizontal) force acting on the dam.
    4. Barrages: A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems.
    5. Embankment Dams: An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core.
    6. Rock-Fills Dams: Rock-fill dams are embankments of compacted free-draining granular earth with an impervious zone. The earth utilized often contains a high percentage of large particles, hence the term “rock-fill”.
    7. Concrete-face rock-fill dams: A concrete-face rock-fill dam (CFRD) is a rock-fill dam with concrete slabs on its upstream face. This design provides the concrete slab as an impervious wall to prevent leakage and also a structure without concern for uplift pressure.
    8. Earth-fill dams: Earth-fill dams, also called earthen dams, rolled-earth dams or simply earth dams, are constructed as a simple embankment of well-compacted earth. A homogeneous rolled-earth dam is entirely constructed of one type of material but may contain a drain layer to collect seep water.

    Major Dams in India

    The major dams in India have helped the inhabitants in a number of ways like:

    1. Providing adequate water for domestic, industry and irrigation purposes.
    2. Hydroelectric power production and river navigation.
    3. These major dams in India and their reservoirs provide recreation areas for fishing and boating.
    4. They have helped in the reduction of floods.

    Some facts about the issue of ageing dams

    • India is ranked third in the world in terms of building large dams.
    • Of the over 5,200 large dams built so far, about 1,100 large dams have already reached 50 years of age and some are older than 120 years.
    • The number of such dams will increase to 4,400 by 2050.
    • This means that 80% of the nation’s large dams face the prospect of becoming obsolete as they will be 50 years to over 150 years old.
    • The situation with hundreds of thousands of medium and minor dams is even more precarious as their shelf life is even lower than that of large dams.

    Impact on the storage capacity

    • As dams age, soil replaces the water in the reservoirs technically known as silt or sediment.
    • Therefore, the storage capacity cannot be claimed to be the same as it was in the 1900s and 1950s.
    • To make matters worse, studies show that the design of many of our reservoirs is flawed.
    • Almost every scholarly study on reservoir sedimentation shows that Indian reservoirs are designed with a poor understanding of sedimentation science.
    • The designs underestimate the rate of siltation and overestimate live storage capacity created.
    • Therefore, the storage space in Indian reservoirs is receding at a rate faster than anticipated.

    Consequences

    • When soil replaces the water in reservoirs, supply gets choked.
    • The net sown water area either shrinks in size or depends on rains or groundwater, which is over-exploited.
    • Crop yield gets affected severely and disrupts the farmer’s income.
    • The farmer’s income may get reduced as water is one of the crucial factors for crop yield along with credit, crop insurance and investment.
    • It is important to note that no plan on climate change adaptation will succeed with sediment-packed dams.
    • The flawed siltation rates demonstrated by a number of scholarly studies reinforce the argument that the designed flood cushion within several reservoirs across many river basins may have already depleted substantially due to which floods have become more frequent downstream of dams. 

    Consider the question “Ageing dams poses several challenges for India. Identify these challenges and suggest the measures to deal with these challenges.” 

    Conclusion

    The nation will eventually be unable to find sufficient water in the 21st century to feed the rising population by 2050, grow abundant crops, create sustainable cities, or ensure growth. Therefore, it is imperative for all stakeholders to come together to address this situation urgently.

    Green India Mission

    • GIM is one of the eight Missions outlined under India’s action plan for addressing the challenge of climate change -the National Action Plan on Climate Change (NAPCC).
    • Launched in February 2014, it is aimed at protecting; restoring and enhancing India’s diminishing forest cover and responding to climate change by a combination of adaptation and mitigation measures.
    • The mission has the broad objective of both increasing the forest and tree cover by 5 million ha,  as well as increasing the quality of the existing forest and tree cover in 10 years.
    • The Mission proposes a holistic view of greening and focuses not on carbon sequestration targets alone, but also, on multiple ecosystem services, especially, biodiversity, water, biomass etc., along with provisioning services like fuel, fodder, timber and non-timber forest produces.
    • It will also increase options of forest-based livelihood of households living in the fringe of those landscapes where the Mission is implemented.

    Limited success of the scheme

    • As of March 2020, plantation under the scheme was undertaken only over 0.14 m ha land.
    • A 2018 parliamentary committee report on GIM found that the scheme was grossly underfunded.
    • The report found that the scheme had also missed its targets by 34 per cent in both 2015-16 and 2016-17 financial years.
    • The committee also pointed out that the afforestation done under the mission was only aimed at increasing tree count without considering the soil and weather conditions.
    • Trees like eucalyptus were planted which make environmental problems worse rather than solving it.
    • Planting of unsuitable trees may cause drought and prevent biodiversity in the regions.
