Development and validation of climatic hazard indicators for roselle (Hibiscus sabdariffa L.) crop in dryland agriculture

Two of the major challenges in achieving food security in the future are: (1) the increase in demand for food due to constant high population growth and (2) the increase in adverse climatic conditions, due to global climate change, that will affect crops. Currently, no universal indicators are avail...
