Strengthening Capacity for Climate Change Adaptation of Moroccan Agriculture

Abstract

Agriculture in the Mediterranean region is substantially challenged by climate change, and olive growers in particular are facing difficulties because of its effects. In this regard, the olive sector can adopt deficit irrigation strategies, to achieve sustainable management practices that improve water productivity and save irrigation water. This chapter aims to investigate the potential impacts of deficit irrigation strategies on Menara olive tree. Agronomical parameters were assessed in 2021 and 2022, focusing on trees subjected to regulated (RDI) and sustained (SDI) deficit irrigation. The results showed that the performances of Menara olive trees under controlled water stress are better under RDI strategy compared to SDI one. Moreover, the RDI strategy, particularly under specific treatment, allowed to reduction of supplied water by 20% and 40% during sensitive and normal periods, respectively. These results highlight the importance of water management strategies and the need to consider their implications on flowering traits, crop yield, and fruit quality over consecutive growing seasons.
