“…Chemical inputs have been replaced with knowledge-intensive crop management techniques like timely fertilizer application and extensive pest management. Other advancements include the use of irrigation systems or agricultural technology that is resistant to harsh weather conditions like drought and floods (Estudillo et al 2023). The results of these developments had their impact on the crop yields and production in Asia.…”

Recent technological advancements have revolutionized agriculture in Asia, leading to significant changes in crop yield stability. This study examines the changing face of crop yield stability in Asia resulting from the increasing adoption of innovative technologies in agriculture. Through a review of current research and case studies, the impact of technology-driven changes on yield levels, variability, and predictability is explored. The study applies a yield stability index (YSI) to evaluate the yield stability of six crops in seven Asian countries during two periods (1961–1994 and 1995–2020), comparing the countries, crops, and stability changes between the two segments. The novelty of the research is the application of YSI, which, contrary to usual stability metrics, can distinguish between rare large extreme yields and frequent minor fluctuations, and based on this feature, evaluates the suitability of the prevailing technologies to local environmental conditions. The YSI is used to evaluate the stability of technologies, indicating whether the technologies can respond well to the annual variations of environmental conditions. Positive YSI values indicate stable technologies that can respond well to the annual variations of environmental conditions, and the concept of a well-technologized crop is used for crops in countries with stable positive YSI values, indicating the suitability of the actual crop to the actual geographical environment. These results can guide production technology developments and the introduction or abandonment of certain crops in certain geographical zones, especially regarding the implications of climate change and global warming. This study highlights the transformative power of technology in improving crop yield stability and food security in Asia, while discussing the potential challenges associated with these changes and the need for continued research to address them.

As the System of Rice Intensification (SRI) has evolved in many ways and in several directions over the past two decades, this review follows the software-naming convention of labeling SRI’s different and subsequent versions as SRI 2.0, 3.0, 4.0, etc. In agroecology as with software, variants are not necessarily linear and can establish new directions as well as the further evolution of existing ones. This overview reviews how rainfed SRI, direct-seeded SRI, mechanized SRI, and other modifications of the initial SRI methodology have emerged since 2000, and how versions of SRI have been improvised to improve the production of other crops beyond rice, like wheat, finger millet, maize, and sugar cane. SRI thinking and practices are also being incorporated into diversified farming systems, broadening the logic and impact of SRI beyond monoculture rice cultivation, and SRI methods are also being used to achieve broader objectives like the reduction of greenhouse gas emissions and the conservation of biodiversity. SRI observations and research have been contributing to the crop and soil sciences by focusing attention on plant roots and soil ecology and by showing how crop management can elicit more desirable phenotypes from a given genotype. Cooperation regarding SRI among farmers, civil-society actors, scientists, private sector agents, governments, and funding agencies has begun introducing noteworthy changes within the agricultural sector, and this collaboration is expected to deepen and expand.
