GS Paper: GS3

  • James Webb Space Telescope

    The James Webb Space Telescope, NASA’s largest space science telescope ever constructed, is scheduled to be sent into orbit in December.

    James Webb Space Telescope (JWST)

    • It is a space telescope being jointly developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
    • It has taken 30 years and $10bn to develop, and is being described as one of the grand scientific endeavors of the 21st Century.

    What is the goal of this telescope?

    • The telescope will be able to see just about anything in the sky.
    • However, it has one overriding objective – to see the light coming from the very first stars to shine in the Universe.
    • These pioneer stars are thought to have switched on about 100-200 million years after the Big Bang, or a little over 13.5 billion years ago.
    • Webb will be picking out groupings of these stars.
    • They are so far away their light – even though it moves at 300,000km per second – will have taken billions of years to travel the cosmos.

    JWST mirror

    • One of the most important objects it will carry is a large mirror which will help collect light from the objects being observed.
    • The primary mirror is made of 18 hexagonal-shaped mirror segments — each 1.32 metre in diameter — stitched together in a honeycomb pattern.
    • The primary mirror is a technological marvel.
    • The lightweight mirrors, coatings, actuators and mechanisms, electronics, and thermal blankets when fully deployed form a single precise mirror that is truly remarkable.
    • Each mirror segment weighs approximately 20 kilograms and is made from beryllium.

    Why beryllium?

    • NASA explains that beryllium was used as it is both strong and light.
    • Beryllium is very strong for its weight and is good at holding its shape across a range of temperatures. Beryllium is a good conductor of electricity and heat and is not magnetic.
    • Because it is light and strong, beryllium is often used to build parts for supersonic airplanes and the Space Shuttle.
    • It added that special care was taken when working with beryllium because it is unhealthy to breathe in or swallow beryllium dust.

    So, it does not have gold?

    • After the beryllium mirror segments were polished a thin coating of gold was applied to it. Gold helps improve the mirror’s reflection of infrared light.
    • The gold was coated using a technique called vacuum vapour deposition.
    • The mirrors are kept inside a vacuum chamber and a small quantity of gold is vapourised and deposited on the mirror.
    • The thickness of the gold is just 100 nanometers. So less than 50 grams of gold was used for the entire mirror.
    • A thin layer of glass was also deposited on top of the gold layer to protect it from scratches.

  • Perform, Achieve and Trade (PAT) Scheme

    A recent report by the Centre for Science and Environment (CSE) has attributed the inefficiency of the PAT scheme to non-transparency, loose targets and overlooked deadlines.

    PAT Scheme

    • Perform Achieve and Trade (PAT) scheme is a flagship program of Bureau of Energy Efficiency under the National Mission for Enhanced Energy Efficiency (NMEEE).
    • NMEEE is one of the eight national missions under the National Action Plan on Climate Change (NAPCC) launched by the Government of India in the year 2008

    Working of the scheme

    • PAT is a market-based compliance mechanism to accelerate improvements in energy efficiency in energy-intensive industries.
    • The energy savings achieved by notified industries is converted into tradable instruments called Energy Saving Certificates (ESCerts).
    • The ESCerts after issuance by the Bureau of Energy Efficiency are traded at Power Exchanges.

    What is PAT cycle?

    • The government shortlists industries and restricts the amount of energy they can consume and defines a time limit of three years by when this restriction should be met as part of PAT.
    • These three years of time are called one PAT cycle.
    • The industries are chosen after in-depth, sector-wise analysis by the government.
    • Industries that participate in this scheme are called designated consumers (DC).
    • Those that overachieve their targets are issued energy savings certificates (ESCerts) that can be traded with industries that have not achieved their targets.
    • Non-achievers have to buy the ESCerts after the three years for compliance.

    Various PAT cycles

    • PAT covered about 13 energy-intensive sectors
    • Sectors included are thermal power plants (TPP), cement, aluminium, iron and steel, pulp and paper, fertilizer, chlor-alkali, petroleum refineries, petrochemicals, distribution companies, railways, textile and commercial buildings (hotels and airports)
    • Announcements for six cycles since 2012 have been made so far

  • India’s electric vehicle push will lead to brighter, greener future

    Context

    The transition to electric mobility is a promising global strategy for decarbonising the transport sector.

    Electricity mobility revolution

    • The global electric mobility revolution is today defined by the rapid growth in electric vehicle (EV) uptake.
    • This phenomenon is today defined by the rapid growth in EV uptake, with EV sales for the year 2020, reaching 2.1 million.
    • Falling battery costs and rising performance efficiencies are fueling the demand for EVs globally.

    Significance of India’s transition to electric mobility

    • India is the fifth largest car market in the world and has the potential to become one of the top three in the near future.
    • India is among a handful of countries that supports the global EV30@30 campaign, which aims for at least 30 per cent new vehicle sales to be electric by 2030.
    • Part of global climate agenda: The push for EVs is driven by the global climate agenda established under the Paris Agreement to reduce carbon emissions in order to limit global warming.
    • Ensuring energy security: It is also projected to contribute in improving the overall energy security situation as the country imports over 80 per cent of its overall crude oil requirements, amounting to approximately $100 billion.
    • Job creation: The push is also expected to play an important role in the local EV manufacturing industry for job creation.
    • Strengthen grid operation: Through several grid support services, EVs are expected to strengthen the grid and help accommodate higher renewable energy penetration while maintaining secure and stable grid operation.

    Battery storage: Opportunities and challenges

    • Promoting sustainable development: With recent technology disruptions, battery storage has great opportunity in promoting sustainable development in the country, considering government initiatives to promote e-mobility and renewable power (450 GW energy capacity target by 2030).
    • Economic opportunity: With rising levels of per capita income, there has been a tremendous demand for consumer electronics in the areas of mobile phones, UPS, laptops, power banks etc. that require advanced chemistry batteries.
    • This makes manufacturing of advanced batteries one of the largest economic opportunities of the 21st century.
    • Concern of absence of manufacturing base: It is estimated that by 2020-30 India’s cumulative demand for batteries would be approximately 900-1100 GWh, but there is concern over the absence of a manufacturing base for batteries in India, leading to sole reliance on imports to meet rising demand.

    Government schemes to promote EV ecosystem

    • To develop and promote the EV ecosystem in the country, government has remodeled Faster Adoption and Manufacturing of Electric Vehicles (FAME II) scheme (Rs 10,000 crore) for the consumer side.
    • It has also launched production-linked incentive (PLI) scheme for Advanced Chemistry Cell (ACC) ( Rs 18,100 crore) for the supplier side.
    • Finally the recently launched PLI scheme for Auto and Automotive Components (Rs 25,938 crore) for manufacturers of electric vehicles was launched.
    • All these forward and backward integration mechanisms in the economy are expected to achieve robust growth in the coming years and will enable India to leapfrog to the environmentally cleaner electric vehicles and hydrogen fuel cell vehicles.

    Benefits of EV ecosystem

    • This will not only help the nation conserve foreign exchange but also make India a global leader in manufacturing of EVs and better comply with the Paris Climate Change Agreement..
    • Battery demand creation: All three schemes cumulatively expect an investment of about Rs 1,00,000 crore which will boost domestic manufacturing and also facilitate EVs and battery demand creation along with the development of a complete domestic supply chain and foreign direct investment in the country.
    • Reduction of oil import bill: The programme envisages an oil import bill reduction of about Rs 2 lakh crore and import bill substitution of about Rs 1.5 lakh crore.

    Conclusion

    India’s push for EV ecosystem is in line with the country’s climate change commitments, will help boost manufacturing sector and also help ensure energy security.

  • A launch window for India as a space start-up hub

    Context

    After the launch of Sputnik in 1957, space race is on again, but this time, private players are on the power field. This has huge implications for original equipment manufacturers (OEMs) in the space sector in India and is a promising venture for global investors.

    Insignificant share of India in space economy

    • 2% India’s share: The space economy is a $440 billion global sector, with India having less than 2% share in the sector.
    • While total early-stage investments in space technologies in FY21 were $68 billion, India was on the fourth place with investments in about 110 firms, totalling not more than $2 billion.

    Reasons for India’s insignificant private participation

    • Absence of a framework: The reason for the lack of independent private participation in space includes the absence of a framework to provide transparency and clarity in laws.
    • Brain drain: Another aspect to throw light on is the extensive brain drain in India, which has increased by 85% since 2005.
    • Policy bottlenecks: Brain drain can be linked to the bottlenecks in policies which create hindrances for private space ventures and founders to attract investors, making it virtually non-feasible to operate in India.

    Suggestions

    • The laws need to be broken down into multiple sections, each to address specific parts of the value chain and in accordance with the Outer Space Treaty.
    • Dividing into upstream and downstream: Dividing activities further into upstream and downstream space blocks will allow legislators to provide a solid foundation to products/services developed by the non-governmental and private sectors within the value chain.
    • Timeline on licensing: With the technicalities involved in the space business, timelines on licensing, issuance of authorisation and continuous supervision mechanism need to be defined into phases.
    • Insurance and indemnification clarity: Another crucial aspect of space law is insurance and indemnification clarity, particularly about who or which entity undertakes the liability in case of a mishap.
    • In several western countries with an evolved private space industry, there is a cap on liability and the financial damages that need to be paid.
    • Need to generate own IP: Currently, many of the private entities are involved in equipment and frame manufacturing, with either outsourced specifications or leased licences.
    • However, to create value, Indian space private companies need to generate their intellectual property for an independent product or service with ISRO neither being their sole or largest customer nor providing them IP and ensuring buy-backs.

    Possibilities for India and the government’s effort

    • India currently stands on the cusp of building a space ecosystem and with ISRO being the guiding body, India can now evolve as a space start-up hub for the world.
    • Already 350 plus start-ups such as AgniKul Cosmos, Skyroot Technologies, Dhruva Space and Pixxel have established firm grounds for home-grown technologies with a practical unit of economics.
    • Last year the Government of India created a new organisation known as IN-SPACe (Indian National Space Promotion and Authorisation Centre) which is a “single window nodal agency” established to boost the commercialisation of Indian space activities.
    • A supplement to the Indian Space Research Organisation (ISRO), the agency promotes the entry of the Non-Government Private Entities (NGPEs) in the Indian space sector.

    Consider the question “Examine the factors responsible for hindering the participation of the private sector in India’s space industry? Suggest the ways to increase the participation of private sector.”

    Conclusion

    To continue the growth engine, investors need to look up to the sector as the next “new-age” boom and ISRO needs to turn into an enabler from being a supporter. To ensure that the sky is not the limit, investor confidence needs to be pumped up and for the same, clear laws need to be defined.

    Back2Basics: The Outer Space Treaty

    • The Outer Space Treaty was considered by the Legal Subcommittee in 1966 and agreement was reached in the General Assembly in the same year ( resolution 2222 (XXI)).
    • The Treaty was largely based on the Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space, which had been adopted by the General Assembly in its resolution 1962 (XVIII) in 1963, but added a few new provisions.
    • The Treaty was opened for signature by the three depository Governments (the Russian Federation, the United Kingdom and the United States of America) in January 1967, and it entered into force in October 1967.
    • The Outer Space Treaty provides the basic framework on international space law, including the following principles:
    • The exploration and use of outer space shall be carried out for the benefit and in the interests of all countries and shall be the province of all mankind;
    • Outer space shall be free for exploration and use by all States;
    • Outer space is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means;
    • States shall not place nuclear weapons or other weapons of mass destruction in orbit or on celestial bodies or station them in outer space in any other manner;
    • The Moon and other celestial bodies shall be used exclusively for peaceful purposes;
    • Astronauts shall be regarded as the envoys of mankind;
    • States shall be responsible for national space activities whether carried out by governmental or non-governmental entities;
    • States shall be liable for damage caused by their space objects; and
    • States shall avoid harmful contamination of space and celestial bodies.
  • Government-owned Contractor-operated (GOCO) Model

    The Army’s ambitious plan for modernization of the Army Base Workshops (ABWs) and implementation of the ‘Government-owned, contractor-operated (GOCO)’ model is delayed, the Comptroller and Auditor General (CAG) said in its report.

    What is GOCO Model?

    • The GOCO model was one of the recommendations of the Lt. Gen. DB Shekatkar (Retd.) committee to enhance combat capability and re-balancing defence expenditure.
    • In GOCO model, the assets owned by the government will be operated by the private industries.
    • Under the GOCO model, the private companies need not make investments on land, machinery and other support systems.

    What is the current system?

    • Maintenance, repair and overhaul (MRO): The Army follows the traditional ‘womb to tomb’ life cycle support management for maintenance, repair and overhaul (MRO) of its costly equipment.
    • Corps of Electronics and Mechanical Engineers (EME): It is responsible for the MRO system.

    Need for GOCO Model

    • High end technologies: In the last three decades, there has been a quantum jump in military technology and the MRO of military equipment has become very complex.
    • Lack of infrastructure: However, some repairs and overhauls have run into problems on account of lack of infrastructure, spares and expertise.
    • Poor performance of Corps: The infrastructure, expertise and work culture has not kept pace with time, leading to below par and inefficient performance.

     Benefits offered by the GOCO Model

    • Time savings: The main advantage of the model is that the targets are achieved in lesser time frame.
    • Competitiveness: Also, it will boost competitiveness among the private entities paving way to newer technologies.
    • Efficiency: The GOCO model will bring in corporate culture, leading to efficiency and accountability.
    • Expertise: Private operators can easily go into partnership with Original Equipment Manufacturer (OEM), both for expertise and spares.
    • Manpower saving: The government can save on manpower — 12,500 personnel workforce of the ABWs.
    • Technical training: This model also opens avenues for absorbing trained retired personnel, which can be built into the contract.

    Major issues with GOCO

    • Costly affair: The corporate world is driven by market forces, which means the GOCO model will be more costly. In most cases, private operators will want better infrastructure, which would have to be upgraded or replaced at government cost.
    • Corporate management: Private operators may not have the expertise to deal with military equipment; they are also unlikely to absorb the existing manpower and will want a younger and better-trained workforce.

  • Ericsson Mobility Report on 5G Subscriptions

    India 5G subscriptions are set to reach 500 mn by 2027, said Ericsson in its report.

    Ericsson Mobility Report

    • The report has added that the total number of smartphone subscriptions is expected to be 810 million at the end of 2021.
    • It is projected to grow at a compounded annual growth rate of 7%, exceeding 1.2 billion by 2027.

    5G penetration in India

    • 5G telecom services are likely to account for 39% of mobile subscriptions or about 500 million subscriptions in India at the end of 2027.
    • 4G is expected to remain the dominant technology in India in 2027.
    • 4G subscriptions are expected to reduce from 68% of mobile subscriptions in 2021 to 55% in 2027 as subscribers migrate to 5G.
    • However, 4G subscriptions are forecast to drop from 790 million in 2021 to 710 million in 2027, showing an annual average decline of 2%.

    Back2Basics: 5G Technology

    • 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
    • It mainly works in 3 bands, namely low, mid and high-frequency spectrum — all of which have their own uses as well as limitations.

    Three bands of 5G

    • The low band spectrum has shown great promise in terms of coverage and speed of internet and data exchange, the maximum speed is limited to 100 Mbps (Megabits per second).
    • This means that while telcos can use and install it for commercial cellphones users who may not have specific demands for very high-speed internet, the low band spectrum may not be optimal for specialised needs of the industry.
    • The mid-band spectrum, on the other hand, offers higher speeds compared to the low band but has limitations in terms of coverage area and penetration of signals.
    • Telcos and companies, which have taken the lead on 5G, have indicated that this band may be used by industries and specialized factory units for building captive networks that can be molded into the needs of that particular industry.
    • The high-band spectrum offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
    • Internet speeds in the high-band spectrum of 5G have been tested to be as high as 20 Gbps (gigabits per second), while, in most cases, the maximum internet data speed in 4G has been recorded at 1 Gbps.

  • [pib] Soil Health Card Scheme

    National Productivity Council (NPC) has carried out a study on ‘Soil Testing Infrastructure for Faster Delivery of Soil Health Card in India’ in 2017.

    What did the study find?

    • In the study it was found that application of fertilizer and micronutrients based on Soil Health Card (SHC) recommendations resulted in 8-10% of savings.
    • It has led to an overall increase in the yield of crops to the tune of 5-6% reported by adopting the SHC recommendations.

     About Soil Health Card Scheme

    • Soil Health Card (SHC) scheme is promoted by the Department of Agriculture & Co-operation under the Ministry of Agriculture and Farmers’ Welfare.
    • An SHC is meant to give each farmer soil nutrient status of his/her holding and advice him/her on the dosage of fertilizers and also the needed soil amendments, that s/he should apply to maintain soil health in the long run.
    • SHC is a printed report that a farmer will be handed over for each of his holdings.
    • It will be made available once in a cycle of 2 years, which will indicate the status of soil health of a farmer’s holding for that particular period.
    • The SHC given in the next cycle of 2 years will be able to record the changes in the soil health for that subsequent period.

    Parameters of SHC:

    • N, P, K (Macro-nutrients)
    • Sulfur (S) (Secondary- nutrient)
    • Zn, Fe, Cu, Mn, Bo (Micronutrients)

  • Risks involved in investment in cryptocurrencies

    Context

    We are witnessing the change where the cult of savers has changed into investors. They are looking for a good return and willing to take the risk.

    Changing the behaviour of the savers

    • There is a new wave of savings and investments in the country that is evolving quite fast.
    • Crypto exchanges assure you that they are safe.
    • But it is the exchange that is safe, not the value of the coin, which will be driven by the market.
    • The equity boom is on, and all the unicorns have delivered excellent results.
    • That’s why bank deposits are no longer on our plates.
    • Banks discouraging deposits: Interestingly, banks today are discouraging deposits with low rates as this is the only way they can manage their balance sheets.
    • Low-interest rate: There are few deployment avenues and paying 5 per cent interest to savers and investing the deposits at 3.35 per cent in the reverse repo auction is a sub-optimal game.

    How safe is investment in cryptocurrencies?

    • From equities, there has been a swift shift to cryptos, which is still a grey area.
    • The regulators/government are wondering what to do. The issue will be discussed in the winter session of Parliament.
    • But investments have been made and there is no stopping this global wave.
    • Currency with no underlying asset: Making money on a currency that has no underlying asset like a metal or other currency and is traded on faith is unique; especially Bitcoin, whose originator is not known by face but by just a name.

    Gaming as a skill

    • There is another door to a new kind of gaming where you make money by making teams and following the matches.
    • The law was first silent, and then confused.
    • But it finally accepted gaming as a skill.
    • Logically, soon we should be able to bet on matches too, if all this is in order.

    Conclusion

    We are witnessing a change in the pattern of holding onto money, where savings get transformed to investment and risk appetite changes from conservative to aggressive. Will this change? Probably not, in the near future, as long as conventional deposits continue to give inferior returns.

  • What is a Tundra Satellite?

    Russia has successfully placed into orbit a military satellite believed to be part of the Kremlin’s early warning anti-missile system. This launch could be delivering a Tundra satellite.

    Tundra Satellite

    • The Tundra or EKS (Edinaya Kosmicheskaya Sistema) series of satellites is the next generation of Russian early-warning satellites.
    • The development of the EKS started in 2000.
    • These satellites carry a secure emergency communications payload to be used in case of a nuclear war.
    • They are launched on Soyuz-2-1b Fregat boosters into Molniya-orbits, inclined highly elliptical 12 h orbits.

    What are Tundra Orbits?

    • A Tundra orbit is a highly elliptical geosynchronous orbit with a high inclination (approximately 63.4°), an orbital period of one sidereal day.
    • A satellite placed in this orbit spends most of its time over a chosen area of the Earth, a phenomenon known as apogee dwell.
    • It makes satellites particularly well suited for communications satellites serving high latitude regions.
    • The ground track of a satellite in a Tundra orbit is a closed figure 8 with a smaller loop over either the northern or southern hemisphere.
    • This differentiates them from Molniya orbits designed to service high-latitude regions, which have the same inclination but half the period and do not hover over a single region.

    Back2Basics: Types of Orbits

    [1] Geostationary orbit (GEO)

    • Satellites in geostationary orbit (GEO) circle Earth above the equator from west to east following Earth’s rotation – taking 23 hours 56 minutes and 4 seconds – by travelling at exactly the same rate as Earth.
    • This makes satellites in GEO appear to be ‘stationary’ over a fixed position.
    • In order to perfectly match Earth’s rotation, the speed of GEO satellites should be about 3 km per second at an altitude of 35 786 km.
    • This is much farther from Earth’s surface compared to many satellites.
    • GEO is used by satellites that need to stay constantly above one particular place over Earth, such as telecommunication satellites.
    • Satellites in GEO cover a large range of Earth so as few as three equally-spaced satellites can provide near-global coverage.

    [2] Low Earth orbit (LEO)

    • A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface.
    • It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface.
    • Unlike satellites in GEO that must always orbit along Earth’s equator, LEO satellites do not always have to follow a particular path around Earth in the same way – their plane can be tilted.
    • This means there are more available routes for satellites in LEO, which is one of the reasons why LEO is a very commonly used orbit.
    • It is most commonly used for satellite imaging, as being near the surface allows it to take images of higher resolution.
    • Satellites in this orbit travel at a speed of around 7.8 km per second; at this speed, a satellite takes approximately 90 minutes to circle Earth.

    [3] Medium Earth orbit (MEO)

    • Medium Earth orbit comprises a wide range of orbits anywhere between LEO and GEO.
    • It is similar to LEO in that it also does not need to take specific paths around Earth, and it is used by a variety of satellites with many different applications.
    • It is very commonly used by navigation satellites, like the European Galileo system of Europe.
    • It uses a constellation of multiple satellites to provide coverage across large parts of the world all at once.

    [4] Polar Orbit

    • Satellites in polar orbits usually travel past Earth from north to south rather than from west to east, passing roughly over Earth’s poles.
    • Satellites in a polar orbit do not have to pass the North and South Pole precisely; even a deviation within 20 to 30 degrees is still classed as a polar orbit.
    • Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km.

    [5] Sun-synchronous orbit (SSO)

    • SSO is a particular kind of polar orbit. Satellites in SSO, travelling over the polar regions, are synchronous with the Sun.
    • This means they are synchronised to always be in the same ‘fixed’ position relative to the Sun.
    • This means that the satellite always visits the same spot at the same local time.
    • Often, satellites in SSO are synchronised so that they are in constant dawn or dusk – this is because by constantly riding a sunset or sunrise, they will never have the Sun at an angle where the Earth shadows them.
    • A satellite in a Sun-synchronous orbit would usually be at an altitude of between 600 to 800 km. At 800 km, it will be travelling at a speed of approximately 7.5 km per second.

    [6] Transfer orbits and geostationary transfer orbit (GTO)

    • Transfer orbits are a special kind of orbit used to get from one orbit to another.
    • Often, the satellites are instead placed on a transfer orbit: an orbit where, by using relatively little energy from built-in motors, the satellite or spacecraft can move from one orbit to another.
    • This allows a satellite to reach, for example, a high-altitude orbit like GEO without actually needing the launch vehicle.
    • Reaching GEO in this way is an example of one of the most common transfer orbits, called the geostationary transfer orbit (GTO).

  • Africa’s Great Green Wall (GGW) Program

    Africa’s Great Green Wall (GGW) program to combat desertification in the Sahel region is an important contribution towards combating climate change, Food and Agriculture Organization (FAO) said in a study.

    Note the countries swept by the GGW project on the African map.

    About GGW Program

    • The Great Green Wall project is conceived by 11 countries located along the southern border of the Sahara and their international partners, is aimed at limiting the desertification of the Sahel zone.
    • Led by the African Union, the initiative aims to transform the lives of millions of people by creating a mosaic of green and productive landscapes across North Africa.
    • The initial idea of the GGW was to develop a line of trees from east to the west bordering the Saharan Desert.
    • Its vision has evolved into that of a mosaic of interventions addressing the challenges facing the people in the Sahel and the Sahara.

    Why was such project incepted?

    • The project is a response to the combined effect of natural resources degradation and drought in rural areas.
    • It aimed to restore 100 million hectares of degraded land by 2030; only four million hectares had been restored between 2007 and 2019.
    • It is a partnership that supports communities working towards sustainable management and use of forests, rangelands and other natural resources.
    • It seeks to help communities mitigate and adapt to climate change, as well as improve food security.
