dc.description.abstractEnFarmers in Madagascar are among the most vulnerable groups in the World. Malagasy agronomic systems are characterised by low to very low soil fertility resulting to food insecurity. The availability of phosphorus (P) is a key issue of climate change mitigation of agronomic systems, as P is the first limiting factor of agricultural productivity. In fact, combination of organic and inorganic phosphorus fertilisers allows overcoming P deficiency in rain fed rice and, at the same time, permit coping with the negative impacts of climate variability when farmers have to modify their conventional farming system and practices, such as the use of triple superphosphate or the delay in crop installation. The production of rain fed rice can be improved from 1t to 3t per ha using mixed organic and inorganic sources of phosphorus. A transformational change is needed for an effective support from the decision makers either in training than in financial and technical supports. The participatory action research is the way for scaling up research results in the field.
