Helping feed the world with rice innovations: CGIAR research adoption and socioeconomic impact on farmers

An economic assessment of adoption of hybrid rice: Micro-level evidence from southern China

“…The choice of conventional rice versus hybrid rice based on rice quality remains a question beyond this paper's scope. The large-scale production and promotion of hybrid rice varieties, known as the Green Revolution, a breakthrough in crop science and technology in the 1960s, was a boon to the world for global food security (He et al, 2020;Mishra et al, 2022). However, the impact of the adoption of hybrid rice technology on the natural ecological environment cannot be ignored.…”

“…In addition, Fan (2020) believes that Green Revolution technologies, such as high-yield rice, have a negative impact on the natural ecological environment because of the use of large amounts of fertilizer and stresses on irrigation water resources, land degradation, and biodiversity damage. In a recent study, Mishra et al (2022) concluded that new rice technologies should be developed with sustainable natural resource management, including water and land management. The authors note that sustainable production methods such as DSR can increase production even as land availability decreases and the frequency of water shortages increases.…”

Assessing returns to research investments in rice varietal development: Evidence from the Philippines and Bangladesh

“…This method has been used to evaluate the welfare effects of new agricultural technologies and research programs within a partial equilibrium framework ( Alston et al, 1998 ; Brennan and Malabayabas, 2011 ; Rejesus et al, 2014 ; Labarta et al, 2017 ; Schreinemachers et al, 2017 ; Shew et al, 2019 ; Sequeros et al, 2020 ). Although the impacts of rice R&D innovations in CGIAR programs have been largely examined in the economic literature through ex post assessment methodologies (see Yamano et al, 2016 ; Mishra et al, 2022 for recent reviews) and through ex ante assessment of new and future technologies, the economic surplus approach offers the advantage that it allows revealing more aggregated benefits over longer time spans. Reviews by Hurley et al (2016) focusing on 492 separate studies published from 1958 to 2015 and by Pardey et al (2016) focusing on 113 studies published from 1975 to 2014 spanning 25 countries indicate that the economic surplus approach remains relevant in the economic literature to examine the returns on R&D investment, although new approaches, mostly econometric-based, are now being used.…”

“…Notwithstanding our contributions to understanding the net economic surplus impact of IRRI and its NARES partners' R&D and extension investments in the Philippines and Bangladesh, it is important to recognize the limitations of the study and mention promising opportunities for future research. First, numerous studies have examined the impacts of rice innovations and R&D investment in CGIAR through ex post impact assessment ( Yamano et al, 2016 ; Mishra et al, 2022 ). These models of ex post impact assessment often focus on individual innovations using a variety of econometric methods that are less restrictive in terms of assumptions than the economic surplus analysis used here.…”

Diffusion of Submergence-Tolerant Rice in South Asia

“…1 1 IRRI and other international agricultural research institutes have been developing and disseminating stress-tolerant crop varieties and other climate-smart agricultural technologies. Yamano et al (2016) andMishra et al (2022) present reviews of recent agricultural technologies and their impacts among farmers in developing countries.…”
