This chapter presents a comprehensive framework for evaluating methane mitigation strategies in dairy farming systems, with particular emphasis on the Indian context. Methane, a potent greenhouse gas primarily produced through enteric fermentation and manure management, represents a significant environmental challenge in dairy production. Through systematic analysis of existing literature and case studies across diverse farming systems, the research identifies six key parameters essential for effective methane reduction: emission reduction effectiveness, economic practicality, environmental co-benefits, scalability, monitoring capability, and social acceptance. The methodology combines theoretical analysis with practical applications, demonstrating how these parameters interact within whole-farm systems. Findings indicate that integrated approaches combining feed optimization, animal husbandry improvements, and manure management yield the most significant and sustainable results. The chapter concludes by outlining policy recommendations that support smallholder farmers in adopting climate-friendly practices while maintaining economic viability. This parameter-based evaluation framework provides a valuable tool for researchers, practitioners, and policymakers working to reduce dairy-related methane emissions while supporting sustainable agricultural development.
