economic valuation of subsistence harvest of wildlife in madagascar
Conservation Biology, 2014Co-Authors: Christopher D Golden, Matthew H Bonds, Justin S Brashares, B Rodolph J Rasolofoniaina, Claire KremenAbstract:Wildlife consumption can be viewed as an ecosystem Provisioning Service (the production of a material good through ecological functioning) because of wildlife's ability to persist under sustainable levels of harvest. We used the case of wildlife harvest and consumption in northeastern Madagascar to identify the distribution of these Services to local households and communities to further our understanding of local reliance on natural resources. We inferred these benefits from demand curves built with data on wildlife sales transactions. On average, the value of wildlife Provisioning represented 57% of annual household cash income in local communities from the Makira Natural Park and Masoala National Park, and harvested areas produced an economic return of U.S.$0.42 ha-1· year-1. Variability in value of harvested wildlife was high among communities and households with an approximate 2 orders of magnitude difference in the proportional value of wildlife to household income. The imputed price of harvested wildlife and its consumption were strongly associated (p< 0.001), and increases in price led to reduced harvest for consumption. Heightened monitoring and enforcement of hunting could increase the costs of harvesting and thus elevate the price and reduce consumption of wildlife. Increased enforcement would therefore be beneficial to biodiversity conservation but could limit local people's food supply. Specifically, our results provide an estimate of the cost of offsetting economic losses to local populations from the enforcement of conservation policies. By explicitly estimating the welfare effects of consumed wildlife, our results may inform targeted interventions by public health and development specialists as they allocate sparse funds to support regions, households, or individuals most vulnerable to changes in access to wildlife. © 2013 Society for Conservation Biology.

links as a Service laas guaranteed tenant isolation in the shared cloud
IEEE Journal on Selected Areas in Communications, 2019Co-Authors: Eitan Zahavi, Alexander Shpiner, Ori Rottenstreich, Avinoam Kolodny, Isaac KeslassyAbstract:The most demanding tenants of shared clouds require complete isolation from their neighbors, in order to guarantee that their application performance is not affected by other tenants. Unfortunately, while shared clouds can offer an option, whereby tenants obtain dedicated servers, they do not offer any network Provisioning Service, which would shield these tenants from network interference. In this paper, we introduce links as a Service (LaaS), a new abstraction for cloud Service that provides isolation of network links. Each tenant gets an exclusive set of links forming a virtual fat-tree, and is guaranteed to receive the exact same bandwidth and delay as if it were alone in the shared cloud. Consequently, each tenant can use the forwarding method that best fits its application. Under simple assumptions, using bipartite graph properties and pigeonhole-based analysis, we derive theoretical conditions for enabling the LaaS without capacity over-Provisioning in fat-trees. New tenants are only admitted in the network, when they can be allocated hosts and links that maintain these conditions. We also provide new results on the numbers of tenants and hosts that can fit while guaranteeing network isolation. The LaaS is implementable with common network gear, tested to scale to large networks, and provides full tenant isolation at the cost of a limited reduction in the cloud utilization.
