This paper identifies rare climate challenges in the long-term history of seven areas, three in the subpolar North Atlantic Islands and four in the arid-to-semiarid deserts of the US Southwest. For each case, the vulnerability to food shortage before the climate challenge is quantified based on eight variables encompassing both environmental and social domains. These data are used to evaluate t...
What does a horticulturist or landscape architect strive to attain when choosing plants for a naturalistic animal exhibit in any major zoo? Should visitors come upon bananas and tropical figs complementing an exhibit featuring giraffes or zebras that naturally roam the hot, arid Serengeti? Let’s hope not. Likewise, they should not be confronted by trees that resemble the acacias of arid Kenya a...
Today, access to sustainable environment for more presence of humans in open space should improve the quality of open spaces and human thermal comfort. Hence, the courtyard as an open space is an important element in solar radiation absorption and providing thermal comfort. The aim of this paper is to investigate the climatic performance of traditional courtyard houses, according to shading ...
Societies in semi-arid areas in developing regions are amongst those, most vulnerable to climate variability and potentially most vulnerable to climate change. The vulnerability to climate variability is caused by the strong restrictions that limited water availability poses on the use of natural resources, by the generally low reliability of water availability and, on the other hand, an often ...
A large reservoir of bioavailable nitrogen (up to approximately 10(4) kilograms of nitrogen per hectare, as nitrate) has been previously overlooked in studies of global nitrogen distribution. The reservoir has been accumulating in subsoil zones of arid regions throughout the Holocene. Consideration of the subsoil reservoir raises estimates of vadose-zone nitrogen inventories by 14 to 71% for wa...

There exists a general consensus that future climate change has the potential to severely impact fragile regions on the planet, especially the semi-arid to arid zones [1]. If adaptation strategies are absent and institutions are not in place for mitigation, economies will suffer and intraand interstate conflicts over the allocation of scarce resources will potentially ensue. These developments,...

Application of green walls still has not attracted interest among the contractors and people, and this can be due to poor growing performance of the plants on these systems. This study investigated the effect of four growing media types (30% cocopeat + 65% perlite + 5% vermicompost, 30% soil + 65% perlite + 5% vermicompost, 30% mushroom compost + 65% perlite + 5% vermicompost and regular soil a...
