The Herero could, therefore, be described as semi-sedentary pastoralists utilising opportunistic management and mobility in order to cope with, and take advantage of the highly variable resource base (Almagor 1980).
The distinctive nature of environmental quality problems in agriculture — an industry based on the extraction of highly variable natural resources under stochastic conditions — has important implications for policy design.
Competition for resources does not have to mean that resources are being used in the same spatial location at the same time; but competition can be displaced by time, especially in rangelands where resource availability is highly variable and resource users are highly mobile (Butt and Turner, this Issue).
Consequently, water in California, is a highly variable and contentious resource that suffers from intense competition among a diverse set of legitimate stakeholders (farms, cities, terrestrial ecosystems and fish), especially during the dry years when it is scarcest.
This is evident from the range of values shown by the error bars of Varnus on Fig. 18 a; as Varanus distributes the cost of monitoring and uses a resource aware approach its resource usage is highly variable dependant upon the available resources.
Their quality is highly variable; some are excellent resources and programs, some are click-bait laundry lists.
One species that inhabits highly variable environments with limited resources relative to their dietary needs and large body size are grizzly (brown) bears (Ursus arctos L). [ 40].
Bumble bees selectively use native and exotic species to maintain nutritional intake across highly variable and invaded local floral resource pools.
But the SNP should bear in mind that oil is not a sustainable resource, not a good resource to hedge our bets on due to highly variable prices, and is most certainly a resource which will continue to gradually decline.
Many pollinator species forage at the landscape scale and depend on floral resources that are highly variable in space and time.
