Morocco is currently facing significant challenges due to the ever–changing climate, with its critical water sources crucial for agriculture, economy, and daily life being greatly affected. In order to thoroughly understand the impact of climate change on the Ghis–Nekor watershed, an in–depth study spanning 38 years (1978–2016) was conducted. This involved examining the meteorological data from three stations and utilizing advanced indices, such as SPI, RDI, and DI. The findings of this study revealed prominent shifts in precipitation patterns, indicating a vulnerability in the region. While there was a general increase in annual rainfall during the specified time period, a sharp decline was observed post–2008. Further analysis of drought confirmed the presence of persistent dry spells and recurring episodes, highlighting the urgent need for effective water management strategies. These crucial findings must be considered by decision–makers for successful climate adaptation, emphasizing the key role played by this study in mitigating the effects of climate change.

The city of Oujda has a very significant production of solid waste that annually exceeds 340000 tons, of which the organic fraction represents at least 70%. In order to promote the recovery of solid organic waste, a study was carried out on an alternative food made from food waste (FW) in the city of Oujda (Morocco). Before being applied on different flocks of chickens (industrial broilers and farmer broilers), this Lab-Prepared Feed was analysed to determine its organo-mineral composition in comparison to other composed poultry feeds that are marketed in Morocco. The results of organo-mineral characterization showed a composition of 13% in total nitrogen, 7% in mineral matter and 4% in fat, while for the composed poultry feeds, these components were 15%, 6% and 5%, respectively. The composition of nutriment found for the studied materials may promote the food waste recovery to be used as a raw material of the Lab-Prepared Feed (LPF). Thus, it may enable to replace, under sustainable view, the composed poultry feeds, which have presently become very expensive due to various economic factors.
