“…In the case of the spread of Acacia and Pinus spp. in the Fynbos floral kingdom of South Africa, for example, the impacts may be contained within the Fynbos (Turpie and Heydenrych 2000). In contrast, HIV or livestock pathogens such as the foot-andmouth virus, are clearly global problems.…”

ABSTRACT. We postulate that the causes of the problem of invasive alien species are primarily economic and, as such, require economic solutions. Invasive alien species are of increasing concern for four reasons. First, introductions are increasing sharply, while mechanisms for excluding or eradicating alien species have been either withdrawn or progressively weakened. Both trends are due to the liberalization of and increase in international travel and trade, an economic phenomenon. Second, the costs of invasions are rising rapidly due partly to increasing human population density, and partly to increasing intensity of production in genetically impoverished agricultural systems. Third, biological invasions are associated with a high degree of uncertainty both because they involve novel interactions, and because invasion risks are endogenous. Actual risks depend on how people react to the possibility of invasions. Fourth, the exclusion and control of invasive species is a "weakest-link" public good. This places the well-being of society in the hands of the least effective provider. We argue that an economic solution to the problem of invasive species has two components. One is to use incentives to change human behavior so as to enhance protection against the introduction, establishment, and spread of invasive behavior. The other is to develop institutions that support the weakest members of global society, converting a "weakest-link" to a "best-shot" public good.

“…All of these papers [70][71][72][73] provide estimates showing that clearing invasive alien plants makes economic sense (in that they deliver positive cost-benefit ratios). These findings rely heavily on the age-biomass models described above, and all do not account for the total economic value which would consider the full suite of economic costs and benefits.…”

“…But they also include a change in ecosystem functioning and hydrology. A number of studies have hown that fynbos mountain catchments are extremely valuable in terms of their water yield, and that the value of changes in water yields exceeded expected restoration costs (Higgins et al, 1997;van Wilgen et al, 1996;van Wilgen et al, 1997;Turpie and Heydenrych, 2000;le Maitre et al, 2002). The result was a major control programme, the Working for Water Campaign, which had both restoration and poverty-alleviation goals.…”
