“…, as reported by Le et al 16 . Accordingly, Synthetic Aperture Radar (SAR) SS 1A data were incorporated into the ORYZA 2000 crop-growth model 16,25 to provide more accurate land-cover data by differentiating rice and non-rice land covers based on its rice growing process database.…”

“…Using time-series data from land-preparation to harvest periods, we applied our phenology-based classification algorithm to map the rice areas. The conversion from multi-temporal satellite images to mapped rice cultivation areas was performed using MAPscape-RICE, a tool that produces seasonal rice, leaf area index (LAI), and start-of-season (SOS) dates 16,25 . The analysis process showed good agreement with SAR-SS 1A statistical data and empirical crop-cut data of Philippines, Vietnam, Cambodia, Thailand, India 25 , and the regional Red River Delta (RRD) of Vietnam 16 .…”

Therefore, the rice cultivated area and rice product for 2019, which were not yet available from traditional data sources of the General Statistics Office of Vietnam (GOSV), were extracted from satellite source data and used to calculate rice straw surplus (RSS).…”

“…The RISR production was calculated using a straw to grain ratio (SGR), where the straw residue yield is estimated using input data of rice production 18,26 . SGR varies with season, location, rice species, harvesting method, and cutting height 16,17 . According to Le et al (2020), a SGR of 1.19 is applicable for Vietnam 16 .…”

Biomass, one of the renewable resources, is expected to play an important role in the world’s energy future. In Asia, rice straw is an abundant agricultural surplus because rice is one of the leading staple food crops in the region. Often, rice straw is burned directly in the field via uncontrolled combustion methods that emit large amounts of short-lived air pollutants, greenhouse gases, and other pollutants. In Vietnam, the energy and environment protection sectors are facing great challenges because of rapid urbanisation and industrialisation. A national strategic choice is to exploit renewable energy, including biomass-derived energy, to achieve energy security and CO2 emission reduction. This study investigates the potential of rice straw as an energy source for power plants at a local scale in Vietnam using data derived from satellite Sentinel-1 images. The results show that Vietnam can produce 2,565 MW from rice straw, for which 24 out of 63 provinces have a potential capacity higher than 30 MW, and the Kien Giang province has the highest capacity (245 MW). The study also analyses limitations and obstacles overcoming which can promote the biomass energy sector in the country.

Closing Rice Yield Gaps in Asia

View full text Add to dashboard Cite

Rice production significantly contributes to greenhouse gas emissions (GHGE), especially methane (CH4) emissions at various cropping stages. A major source of methane emissions is the decomposition of fertilizers and organic residues in flooded fields during the irrigation cycle. CORIGAP technologies and practices are mainly associated with closing yield gaps by increasing productivity and profitability but have been co-designed to address climatic challenges and to minimize negative environmental impacts. Therefore, over the last decade, the CORIGAP interventions not only helped to reduce yield gaps substantially but also resulted in a significant reduction of the carbon footprint (CF) in rice production. This chapter starts with an in-depth synthesis of scientific-based evidence and knowledge on challenges and constraints to reducing rice CF in CORIGAP countries. The chapter introduces solutions that have been proven to reduce GHGE, in particular, Alternate Wetting and Drying (AWD), rice-straw management, mechanization, and postharvest management. The latter two approaches include laser land leveling, mechanized direct seeding and transplanting, and paddy grain drying will be described in more detail. In addition, life cycle assessments will outline the quantification of the carbon footprint in rice production, for these specific technologies. The chapter presents three country case studies (Thailand, Indonesia, and Vietnam) from data collected through CORIGAP activities to estimate GHGE reductions associated with implementation of best practices for lowland irrigated rice production. Lastly, this chapter provides the outcomes related to GHGE reduction and offers specific recommendations that can be easily implemented in other countries.
