“…The urban neighborhoods, represented by shantytowns and industrial-residential neighborhoods are placed at the opposite end of the gradient. Following Morello et al (2000), shantytowns are less urbanized than industrial-residential neighborhoods because of their low impervious surface coverage and an inadequate supply of urban services.…”

“…Although the conversion of natural or semi-natural ecosystems to urban ecosystems is a slow process, it is usually irreversible (Matteucci et al, 1999;Morello et al, 2000). Urban ecosystems provide fewer ecological services, such as the capacity to control animal and plant populations that may prevent pest outbreaks (Morello et al, 2000).…”

“…Urbanization often occurs at the expense of highly productive agricultural land [25]. It has been estimated that the growth of the Metropolitan Area of Buenos Aires encroaches up to around 45 ha of agriculture land per year (Morello et al 2000). Furthermore, urbanization demands soil materials for industries and the construction sector.…”

Assessing the sustainability of complex development processes requires multi-causal and integrated analyses. We develop a system-based methodology, rooted Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.in interdisciplinary discussion and consensus building between 15 experts, to construct a multi-causal diagram which examines the sustainability of the Argentine Pampaś process of agriculturization. The resulting diagram includes 25 factors and provides a big-picture of the multiple dimensions and interrelations affecting sustainability. According to this examination, the increasing concentration of production and the incorporation of technological innovations, triggered by economic and institutional factors, are the cause of environmental distresses and social changes, whose consequences for sustainability are still highly disputed. Nevertheless, the symptoms of both environmental and social unsustainability are more evident in the case of the extraPampean regions than in the Pampas. This suggests that the Pampean agriculture model should not be transferred to these regions without substantial modifications. The experts did not reach consensus on whether the agriculturization process is overall sustainable or unsustainable. Lack of consensus revolved mainly around opposing perspectives regarding the significance of the threats to environmental sustainability. The magnitude of socio-distributive unbalance and loss of rural jobs were also contentious. Yet, the paper shows how the exercise of building a joint causal diagram was undoubtedly helpful for linking piece-meal disciplinary facts, brought in from all fronts, into a comprehensive and coherent picture.

“…Conversion from natural to urban ecosystems is an ever-growing, and virtually irreversible, process that impoverishes ecological services for humankind, including long-term capacities to control synanthropic species and prevent pest outbreaks (Morello et al 2000). However, citizens' expectations for quality-of-life grow constantly, accentuating the need for effective rodent control programmes accounting for sanitary, economic and aesthetic issues.…”

Poison-Based Commensal Rodent Control Strategies in Urban Ecosystems: Some Evidence Against Sewer-Baiting

Sewers are historically considered the main reservoir for commensal rodents, posing threats to urban ecosystem health. Aboveground rodent signs are often assumed to give clues to high sewer infestation, which can chronically restock surface areas. Thus, current sewer-baiting programmes are mostly reactive, responding to increased surface infestation. Conversely, proactive sewer-baiting (regardless of infestation levels) is often disregarded because cost-effectiveness is not always addressed. We explored the extent to which the surface infestation is related to rodent feeding activity on sewer and surface baits by analysing a set of proactive bait records in Bologna city, Italy. Sewer bait intakes were significantly lower than surface ones, suggesting that proactive sewer-baiting is generally less effective. As surface infestation increased, probability of recording surface bait intake increased significantly but this was not reflected by increased sewer bait intake, suggesting that surface infestation is not always a reliable indicator of sewer infestation. This should discourage the use of reactive sewer-baiting as a routine strategy. Poison-based control programmes by themselves are scarcely predictable and strategically limited, and ideally they should be handled within an ecologically based integrated pest management approach for achieving satisfactory results.
