Diagnosis of land condition is a basic prerequisite for finding the degradation of a territory under climatic and human pressures leading to desertification.
It is a heterogeneous territory in climatic terms, with a mainly eastward and southward decreasing precipitation gradient (range 200 2000 mm) and a mainly northward decreasing temperature gradient [30].
As a result of the large surface area occupied by Nigeria, the national territory covers different climatic and ecological zones.
The present study shows a significant association between hospital emergency visits for wheezing and gastroenteric disorders in children 0 2 years of age and air pollution levels in six urban cities in Italy, located in different geographical areas (northern, central and southern Italy, plus seaside localities and hinterland territory) having different climatic conditions.
While broadleaved tree species are widespread over the whole Italian territory and across different climatic regions, conifers are represented mostly by alpine species (P. abies, Larix decidua Mill., P. sylvestris) each of them occupying a specific ecological niche with a distribution limited to Northern Italy (Fig. 1a).
The installation and extended usage of a significant number of Auto40 flow cytometers in Chad also allowed us to assess the performance of these CD4 T cells counters in situations of actual use, across an entire country with harsh climatic conditions and a large geographical territory.
Either via pathoadaptive evolution or genetic recombination and/or the acquisition of new virulence genes, pathogens may rapidly evolve mechanisms to cause disease on new hosts, within new territories and under new climatic conditions, outpacing the capacity of the hosts to adapt to the conditions and the new pathogenic burden.
Climatic conditions and good soil favour agriculture.
Including, for instance seismic risk, sociocultural practices of the population, as well as the diversity that characterizes the climatic and geographical data of the entire national territory, by following the existing national legislation, regulations and standards.
For this, the used method (1) generates future time series of climatic variables (precipitation, temperature) spatially distributed over the territory for potential aquifer recharge (PAR), and (2) simulates them within previously calibrated spatial PAR or NAR recharge models from the available historical information to provide distributed PAR or NAR time series.
