In the last 30 years, rice production in Peru has grown 4.88 times. Rice in the Camaná Valley of the department of Arequipa is one of the most important food crops in the regional economy with a world record in yield for paddy rice. The objective was to analyze the innovation system in the adoption of IR-43 (NIR) and Tinajones rice varieties by rice farmers in the Camaná Valley and determine the impacts on improvements in the quality of life of farmers. This study used the innovation systems framework to explore four key aspects of innovation systems: Actors, the roles they play and the activities in which they are involved, attitudes and practices of the main actors, patterns of interaction between the main actors and the enabling environment. It was determined that the adoption of IR-43 (NIR) and Tinajones varieties was facilitated by the existence of a diversity of collective intelligence mechanisms to organize interactions for innovation, government actors have been identified (INIA, SENASA, Agrarian Agencies); private companies (CORDESA Camaná, commercial houses, phytosanitary companies), media, rice producers, a sociotechnical regime that constitutes the mills, financing entities, market information and marketing agents, forming a network of social and economic actors, which interact with each other for the adoption of rice varieties. The livelihoods of producers have been favored by human, social, natural, financial and political capital. The increase in yields and a better price of the product allows them to improve their economies.

This study analyzed the socio-economic, institutional, and environmental factors influencing the adoption of high-yielding rice varieties, IR-43 and Tinajones, in the Camaná Valley, Peru. Using a mixed-methods approach over 24 months, data were collected from 300 farmers through surveys, semi-structured interviews, and environmental assessments using life cycle analysis (LCA). Regression analysis identified farm size, access to credit, and institutional support as the primary drivers of adoption, with larger farms exhibiting adoption rates 40% higher than smaller ones due to better financial resources. Education and market access also significantly influenced adoption, with educated farmers and those with strong market integration showing a 25% higher likelihood of adoption. However, adoption came with environmental trade-offs: IR-43 and Tinajones required 10–20% more water and produced 15% higher greenhouse gas emissions than traditional varieties. Structural equation modeling revealed that education and institutional support indirectly increased yields by 30% through improved access to credit and training. The findings underscore the need for policy interventions that balance socio-economic benefits with environmental sustainability, integrating measures such as optimized irrigation and organic fertilization to mitigate negative environmental impacts. These findings highlight the need for integrated policy interventions that support both the socio-economic and environmental sustainability of rice farming in semi-arid regions like the Camaná Valley. © 2025 Elsevier B.V., All rights reserved.
