The article discusses the ongoing negotiations between the United States and India regarding the opening of India's agricultural market to genetically modified (GM) crops as the July 9 deadline approaches. It presents various perspectives about GM crops and their implications for Indian agriculture, especially in light of India's existing agricultural policies and practices.

Summary:

• Negotiation Pressure: US negotiators are urging India to allow GM crops, which poses a significant challenge for sealing a trade deal given India’s resistance.

• India’s Stance: Finance Minister Nirmala Sitharaman emphasizes that agriculture and dairy are "sacrosanct red lines," warning that accepting GM imports could threaten farmers' livelihoods and food safety.

• Global GM Adoption: Since 1996, global adoption of GM crops has increased dramatically, with over 200 million hectares cultivated across 76 countries by 2023.

• Current Status of GM Crops in India: The only GM crop currently approved in India is cotton (Bt cotton), introduced in 2002 under the Atal Bihari Vajpayee government. Today, over 90% of India's cotton area relies on Bt cotton, with its seed used in animal feed.

• Impact on Cotton Production: The introduction of Bt cotton led to a substantial increase in cotton production—from 13.6 million bales in 2002-03 to 39.8 million bales in 2013-14, with significant productivity gains.

• Decline in Cotton Yields: Since 2015, yields in cotton have decreased from 566 kg/ha to around 436 kg/ha, lower than the global average of 770 kg/ha. This decline is attributed to pest outbreaks, regulatory issues, and a ban on next-generation cotton seeds.

• Illegal HT-Bt Cotton: The emergence of illegal herbicide-tolerant Bt cotton reflects farmer frustrations. Estimates suggest that 15-25% of cotton acreage may be planted with these unregulated seeds, risking crop failures without any official recourse.

• Regulatory Challenges: The Cotton Seed Price Control Order of 2015 reduced seed royalties, disincentivizing research and development in the cotton sector. Additional regulations imposed further limits, which deterred global biotech firms from investing in India's agricultural innovation.

• Stalled Innovations: Other GM crops like Bt brinjal and GM mustard face approval delays. The moratorium on Bt brinjal since 2009 and conditional release of GM mustard in 2022 remain uncommercialized due to bureaucratic blockages.

• Call for Policy Reform: The article advocates for a shift towards a science-led approach in agricultural policy. Emphasizing PM Modi's “Jai Anusandhan” slogan, it argues for the need for India to embrace biotechnology innovations to enhance productivity and prosperity in rural areas.

Key Points:

• Negotiations for GM crop opening between the US and India intensify as a July 9 deadline looms.
• India's government declares agriculture and dairy as protected sectors against GM imports.
• Over 200 million hectares of GM crops are cultivated globally as of 2023.
• Bt cotton has significantly increased India's cotton production since its introduction.
• Cotton yield decline and pest outbreaks mark current challenges faced by Indian farmers.
• Illegal introduction of HT-Bt cotton raises concerns about compliance and risk management.
• Restrictions and regulations hinder the development of new biotech seeds in India.
• The moratorium on existing GM crops denotes a conservative regulatory environment.
• Strong leadership in science and technology is crucial for agricultural innovation in India.
