In inland aquifers, a decrease in groundwater recharge can lead to saltwater intrusion of neighbouring saline aquifers, and increased evapotranspiration in semi-arid and arid regions may lead to the salinisation of shallow aquifers. Originality/value – In Africa, climate change and variability have...
In addition to the world climatic mapping program, CSIRO has developed more detailed climatic mapping programs for a wide range of regions, including Africa, mainland South-East Asia, and Latin America, as well as for individual countries, including Australia, Cambodia, China, Indonesia, Laos, Tha...
RegionsGlacier and glacial landscape evolutionProjections Russian Arctic (63°–81°N/45–62°E, 1899 m) *Glaciers of the northern Urals lost half their volume from the 1960s to 2018 and many disappeared. *Glaciers in Novaya Zemlya retreat continuously from 1992, except in the northeastern ice...
While climate parameters and species pools display a continuous evolution along the climatic gradient, these stable structural states have discontinuous transitions, resulting in regions containing mosaics of alternative stable states. Soils appear to have little effect inside the climatic stable state ...
The issues considered under sub-theme 1.2 included the potential of the various agricultural production systems in the various agro-ecological regions of Africa; the policies needed to increase not only the level but also the effectiveness of investment in the agricultural sector (e.g., absorptive ...
This is documented by a major increase in the delta18O values of pedogenic and groundwater carbonates at these times. The data suggest that meteoric water of the earlier, more humid climate was 2-4 per mil lower in 18O content than modern waters of these regions....
Zone IVa is characterized by consistently high temperatures and significant humidity throughout the year. The standard testing conditions for pharmaceutical products in this zone are 30°C with 65% RH. This zone includes regions like Southeast Asia, Central Africa, and parts of South America, where...
The most significant climatic change that has occurred has been a long-term reduction in rainfall in the semi-arid regions of West Africa. This was on the order of 20 to 40% in parts of the Sahel. There have been 3 decades of protracted aridity. Nearly all of Africa has been affected...
Climate change has impacted crop production and food security in regions of smallholder dominance (Eissler et al., 2019; Hussain et al., 2019). Crop responses to climate variability and change are variable but have mostly been detrimental (Krishnan et al., 2011; Lobell et al., 2007). Show...
Ixodes ricinusticks have wide geographical and climatic ranges spanning all over Europe and some regions in northern Africa and western Asia13. Long-term observation of the questing activity ofI. ricinusnymphs, for both phenology and abundance, has been an important indicator for the exposure risks ...
