The System of Rice Intensification (SRI) is a farming methodology that aims to increase the yield of rice while using fewer resources and reducing environmental impacts. The method was developed by a French Jesuit Father Henri de Laulanié in Madagascar [ 1 ] and built upon decades of agricultural experimentation.
By 1989, he had re-engineered the method into a sustainable, integrated organic rice and duck farming system that could be replicated. Today, in addition to protecting his family’s health, Furuno now produces crop yields without the use of chemicals that equal or surpass those of farmers still using conventional methods.
Hence, the method and experiment provide sustainable agriculture means in Southern China. Rice production in China is severely constrained by “excessive water consumption, labour shortage, large environmental footprint, and low economic profit” [21] – this makes rice ratooning a favourable practice for production. From the former, rice ...
Getting customers to buy into local, small-scale, environmentally-sustainable farms and farmers on the front end of the process has long been the goal of community supported agriculture, or CSA.
This form of agriculture is sustainable at low population densities, but higher population loads require more frequent clearing which prevents soil fertility from recovering, opens up more of the forest canopy, and encourages scrub at the expense of large trees, eventually resulting in deforestation and soil erosion.

A rice-fish system is a rice polyculture, a practice that integrates rice agriculture with aquaculture, most commonly with freshwater fish. It is based on a mutually beneficial relationship between rice and fish in the same agroecosystem. The system was recognized by the FAO in 2002 as one of the first Globally Important Agricultural Heritage ...
Rice terraces in Sa Pa, Vietnam. Rice terraces of the Hani people in Yunnan, China. Rice terrace in the Fukuoka Prefecture, Japan. In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming.
High-yielding rice varieties developed for continuously flood irrigation rice system still produce high yield under safe AWD. [6] This method can even increase grain yield because of enhancement in grain-filling rate, root growth and remobilization of carbon reserves from vegetative tissues to grains.
