Ultimately, a threshold was reached towards the end of the YD, and the Harifian adaptation ceased to be viable, so they had little choice but to abandon their former territories in the Negev and northern Sinai to more favourable environmental conditions, near and, perhaps, far.

The Godavari Basin experiences diverse climatic conditions ranging from humid in the Western Ghats to semi-arid in central and western regions. Frequent hydrological droughts have plagued the Godavari basin.

Further, assessing the regional control of streamflow drought deficit and intensity in a large river basin like Godavari is crucial. The findings show that streamflow drought is worst in central and eastern Godavari. Additionally, dammed and undammed locations have different streamflow drought characteristics.

Increased drought seasons correlated with changes in annual temperature, dew point, and soil temperature. Vegetation growth depended not only on rainfall amount but also on the number of rainfall events and accumulation. Optimal rainfall events per year ranged from 10 to 15, with 70 mm being the threshold for healthy vegetation growth. However, the probability of rainfall events over 80 mm was less than 5%, while low rainfall seasons (1–17 mm) were more likely (90–99% chance). Additionally, vegetation cover varied between protected sites, indicating the complexity of arid lands influenced by factors like topography and soil type. These findings suggest a continued decrease in vegetation coverage, leading to more drought seasons and impacting water and food security. We recommend further research on supplementary irrigation to support native species, understand their seasonal growth stages, and better comprehend soil-plant-water connections and water requirements.

Ecosystem modeling combined with Geographic Information Systems (GIS) is a promising tool for estimating carbon stocks in the Caatinga, where field sampling campaigns are generally expensive and have scarce research funding opportunities. Furthermore, it also allows the evaluation of the effect of environmental changes on C stocks in long-term studies, which is essential for creating and implementing public policies to mitigate and adapt to the impacts of climate change on the ecosystem.
