Ecological Intensification in Asian Rice Production Systems

Abstract

More rice is needed to feed the increasing population in Asia and beyond. Although rice breeders and scientist have produced high yielding varieties, soils have been degraded by intensive agriculture. Hence alternative intensification strategies are needed for sustaining the rice production in Asia. This chapter reviews rice production systems in Asia and potential ecological intensification stratagies. There are well adopted, genetically diverse rice groups performing under varied soil and climatic conditions. Due to the varied topography, soil types, microclimate and cultural diversityDiversitythroughout, rice production systems are diverse. Ecosystem services from these diverse rice ecosystems are also unique to the location of origin, culture of the people associated, functioning style and the expected outcome of each of these rice production systemsIntegrated Nutrient Management.
