Managing invasive alien species with professional and hobby farmers: Insights from ecological-economic modelling

Are preserved farms actively engaged in agriculture and conservation?

“…A number of studies have started with the premise that hobby farms are destructive to peri-urban commercial agriculture, either because they are not "actively engaged" (Layton, 1978;Blank, 2005;Hart, 1992;Ceddia et al, 2009) or because they fragment rural landscapes that previously enjoyed spatial critical mass (Layton, 1978;Daniels, 1986;Stobbe et al, 2009). While hobby farms are clearly smaller than their more commercial counterparts, small farms are the norm in states like New Jersey, Delaware, and Maryland (Table 2).…”

“…If lifestyle farmers are disproportionately attracted to preserva-tion programs, an obvious concern is that they will invest less in their operations because of their part-time status or lack of business acumen (Daniels, 1986;Lambert et al, 2007;Ceddia et al, 2009). A disproportionate number of participants could be seeking to "cash out" a portion of their land asset as part of a transition toward retirement.…”

A structured war-gaming framework for managing extreme risks

“…Among the existing studies, two lines of research are of particular relevance to the model we developed. The first group addresses the decision-support needs of policy makers by integrating established ecological models with economic management frameworks (Barbier, 2001;Cacho et al, 2008;Carrasco et al, 2010;Ceddia et al, 2009;Crepin et al, 2011;Epanchin-Niell et al, 2014;Hyder et al, 2008;Sharov and Liebhold, 1998). The second line of research has developed spatially explicit approaches using stochastic simulations that combine environmental variables and dissemination behaviors in order to characterize uncertainty in spread patterns over time (Carrasco et al, 2012;Epanchin-Niell and Hastings, 2010;Fernandes et al, 2014;Hastings et al, 2005;Meier et al, 2014;Rafoss, 2003;Touza et al, 2010;Yemshanov et al, 2009).…”

When ignorance is not bliss: Pest control decisions involving beneficial insects

“…Some of the earlier work in this area analyzes the effects of a pest's growing resistance to the pesticide on the optimal use of the pesticide over time (Plant et al, 1985;Regev et al, 1983). More recent work focuses on optimal management of invasive species across time and space (Brown and Zilberman, 2002;Ceddia et al, 2009). Some work has added a predaceous Ecological Economics 107 (2014) [104][105][106][107][108][109][110][111][112][113] insect population, but without considering pesticide toxicity to the predator (Marsh et al, 2000;Schumacher et al, 2006).…”
