The Global Forum on Innovations for Marginal Environments is organized in view of enormous impact of soil and water salinization and climate change on ecosystems, agricultural productivity, livelihoods and food security worldwide. It is important to clearly map the marginal areas already afflicted by salinity, poor quality water, very high temperature posing risks on a global scale and develop and implement the adaptation and mitigation strategies with robust policy support to effectively and efficiently address the adverse effects.
