While India’s expansion of the rice–wheat cropping system led to the production of more food, it has also led to degradation of the natural environment, and concerns over the sustainability of the practice. This report looks at the returns on investment of ACIAR projects that sought to develop alternative practices for growing rice and wheat sustainably, and designing a machine that allows direct seeding of wheat into rice stubble.
