NEWS:The U.S. has imposed a 25% tariff plus penalties on Indian imports

GS-2 international relation

citing India’s continued defense and energy ties with Russia and persistent trade barriers. This comes amid stalled negotiations on a mini trade deal and growing friction in India-U.S. economic relations.

• The U.S. imposed a 25% tariff plus penalty on Indian imports, citing India’s trade ties with Russia and market restrictions.
• President Trump criticized India’s tariff and non-tariff barriers, calling its economy “dead” and raising concern over oil deals with Pakistan.
• Talks on a mini-trade deal have stalled; India paused negotiations amid lack of consensus.
• USTR Jamieson Greer indicated a bilateral trade agreement (BTA) is still under negotiation.
• India’s Commerce Ministry reaffirmed its sovereign trade choices, especially in energy and defense.
• The tariff disadvantages India relative to regional competitors like Vietnam, Indonesia, and Malaysia.

Tariff Barriers

Tariff barriers are government-imposed taxes on imports that raise the price of foreign goods to protect domestic industries.

• A tariff is a tax placed on imported goods to make them more expensive than local products.
• Tariffs reduce the competitiveness of foreign goods in the domestic market.
• For example, if Country A adds a tariff on toys from Country B, those toys become costlier in Country A.
• Consumers may shift to locally made products due to higher prices of imports.
• Tariffs can protect local jobs and industries, such as steel manufacturing, from cheaper foreign alternatives.
• The impact of tariffs includes reduced import volumes and possible price increases for consumers.

Non-Tariff Barriers

Non-tariff barriers are trade restrictions that use rules, regulations, or procedures instead of direct taxes to limit imports.

• These barriers include product standards, size limits, and safety requirements for imported goods.
• For instance, a country may require toys to pass safety checks before they can be sold.
• Customs paperwork or complicated procedures can delay or discourage imports.
• Even without taxes, non-tariff barriers make it harder for foreign businesses to access domestic markets.
• They protect consumers and local industries through regulation rather than cost.
• The key difference from tariffs is that non-tariff barriers use regulations instead of taxation to control trade.

NEWS:On July 30 2025 ISRO successfully launched the NISAR satellite aboard GSLV F16

GS-3 SCIENCE AND TECHNOLOGY

Developed jointly by NASA and ISRO, NISAR is the world’s first dual-frequency Earth observation radar satellite aimed at enhancing global environmental monitoring and disaster management.

• GSLV-F16 launched the NASA-ISRO NISAR satellite into a sun-synchronous orbit on July 30.
• NISAR combines NASA’s L-band and ISRO’s S-band radars in a single observatory.
• It will monitor earth processes such as glacier flow, urban subsidence, land use, and biomass changes.
• The satellite offers 12-day revisit cycles with high spatial and temporal resolution.
• Data will be publicly available and support climate models, disaster risk reduction, and policy planning.
• The mission enhances India-U.S. space collaboration and technology transfer.
• ISRO faces challenges in data processing infrastructure and follow-on mission planning.

NISAR Payloads

The NISAR mission carries two primary payloads, which are the advanced radar instruments that will be used for Earth observation:

L-band Synthetic Aperture Radar (L-SAR):

Developed by NASA’s Jet Propulsion Laboratory (JPL)

Operates at a wavelength of approximately 24 cm

Designed to penetrate through vegetation and surface materials

Provides high-resolution imagery for studying solid Earth processes, ice sheet dynamics, and biomass changes

S-band Synthetic Aperture Radar (S-SAR):

Developed by the ISRO

Operates at a wavelength of approximately 10 cm

Optimized for studying surface deformation and changes in biomass

Provides high-resolution imagery for monitoring natural hazards, such as earthquakes, volcanic activity, and landslides

NEWS:Transforming early childhood care and education

GS-2 governance

The NEP 2020 is reshaping India’s Early Childhood Care and Education (ECCE) system by integrating preschool classes in government schools, traditionally served only by Anganwadis

• NEP 2020 mandates universalisation of ECCE by 2030, targeting children aged 3–6 years.
• Government schools are being equipped with Balvatika (preschool) classes, expanding public ECCE infrastructure.
• States/UTs are using the Samagra Shiksha budget for establishing preschool classes, though unevenly.
• Rising preference for schools over Anganwadis is triggering migration of 4–6-year-olds.
• Shift of focus towards home-based care for 0–3-year-olds via home visits by Anganwadi workers.
• The ‘Poshan Bhi Padhai Bhi’ initiative aims to integrate nutrition and education in Anganwadi services.
• Concerns raised about ‘schoolification’ of preschooling, risking play-based learning.

National Education Policy 2020?

The new National Education Policy (NEP) 2020 is the first education policy of the 21st century in India, which replaces the previous National Policy on Education (NPE) 1986.

The Ministry of Education formed a committee under Dr. K Kasturirangan, which outlined this new policy.

The National Education Policy 2020 proposes various reforms in school and higher education, including technical education, that are suited to 21st-century needs.

5 foundational pillars of NEP 2020: Access, Equity, Quality, Affordability, and Accountability.

This policy is aligned with the 2030 Agenda for Sustainable Development.

It aims to transform India into a vibrant knowledge society and global knowledge superpower by making both school and college education more holistic, flexible, and multidisciplinary and aimed at bringing out the unique capabilities of each student

NEWS:Why the world needs better green technologies

GS-3 science and technology

As countries scale up renewable energy to meet climate goals, concerns rise over the long-term sustainability and efficiency of silicon-based solar panels in delivering clean energy and enabling green hydrogen technologies.

• Silicon photovoltaics dominate solar power but have low efficiency (15–18%), requiring large land areas.
• New technologies like gallium arsenide thin films have achieved up to 47% efficiency in labs.
• India produces 6 GW of silicon cells, but efficiency gaps limit progress toward decarbonisation.
• Green hydrogen’s viability depends heavily on the efficiency of solar input, which silicon limits.
• Artificial photosynthesis (APS) and Renewable Fuels of Non-Biological Origin (RFNBOs) offer promising alternatives.
• Current hydrogen storage and transport technologies are costly and inefficient.
• India imports ~85% of its energy, highlighting the need for domestic R&D in futuristic renewables.

artificial photosynthesis (AP) — 

                  which they feel can aid mitigate effects of emissions made by use of fossil fuels.

How it works?

This artificial photosynthesis (AP) harnesses solar energy and converts the captured carbon dioxide to carbon monoxide (CO) (using a photosensitizer), which can be used as a fuel for internal combustion engines.

• Here, scientists are essentially conducting the same fundamental process in natural photosynthesis but with simpler nanostructures.
• This process of converting CO2 into solar fuel also generates oxygen from water.
