However, with an increase in demand of the land for infrastructure development (for residential, commercial and strategic facilities), for which their stabilization may be essential, and a need to utilize these (aeolian) sands as a construction material, particularly due to acute scarcity of sand, their complete characterization becomes essential.
The scarcity of sand is also a function of geography.
The scarcity of LGM dune sand elsewhere in the dune field is interpreted as the result of intensive aeolian activity without substantial net sand accumulation.
Table 4 shows that 19 and 5%% respondents from severe drinking water scarcity areas use pond sand filters respectively to get safe drinking water with minimal salinity and arsenic contamination, whereas 33 and 15%% of the respondents from moderate drinking water scarcity areas utilized the same practice.
Instead of filling buckets with water — a scarcity in the Gaza Strip — people are dumping sand and rocks on their heads, in reference to the rubble of thousands of Gazan homes razed by Israeli airstrikes.
These observations reflect the scarcity of both hyaluronidase transcript and hyaluronidase protein in sand fly salivary glands, and at the same time underline the remarkably high specific activity of the enzyme.
The Shell folk insist that they recycle much of it, but even they accept that water scarcity will become an issue if many tar-sands operations take off in future.
The climatic conditions are harsh including scarcity of rain, intense sunshine, high evaporation, dry air and blowing sand.
Besides the pond sand filter and rainwater harvesting technology, 8 and 18%% of respondents from severe and moderate scarcity areas respectively use deep tube wells with overhead tanks installed by the local NGO Iswaripur Development Foundation (IDF), with GIZ German Development Cooperationn) assistance (Fig. 9b).
High evaporation rates in desert areas lead to water scarcity and in turn salinity components accumulate in the surface layers of the sand dunes.
Sand rice is a potential food crop resilient to ongoing climate change; however, partly due to the scarcity of genetic information, this species has undergone only little agronomic modifications through classical breeding during recent years.
