“…However, it remains unclear whether restoration of a single hedgerow and other small-scale, local restoration strategies can compensate for low complexity at the landscape scale and how far benefits of edge restoration may extend into adjacent fields. Uncertainty as to how hedgerow establishment will alter pest and natural enemy insect communities, and ultimately pest control and crop yield, remain a major barrier to landowners' willingness to devote time and money to hedgerow restorations and other CBC strategies on their farms (Griffiths et al, 2008;Stamps et al, 2008).…”

a b s t r a c tWithin-farm habitat enhancements such as hedgerows could aid pest control in adjacent crops; however, there is little information on whether small-scale restoration impacts pests and natural enemies, and crop damage, and how far effects may extend into fields. We compared restored, California native perennial hedgerows to unenhanced field edges consisting of commonly occurring semi-managed, nonnative weeds. Pest and natural enemy communities were assessed in both edge types and into adjacent processing tomato fields. Using sentinel pest eggs, pest control was quantified, and pest pressure and crop damage was compared between field types. Economically-important pests were fewer and parasitoid wasps were more abundant in hedgerows than weedy crop edges. There was no difference in predatory arthropod abundance between edge types, but there was greater predator richness in hedgerow than weedy edges. Predatory lady beetles were more abundant and aphids were lower in fields with hedgerows, up to 200 m into fields, the maximum extent of observations. Fewer of the fields adjacent to hedgerows reached threshold pest levels requiring insecticide application. Benefits of hedgerows to pest control from parasitism extended to 100 m but not 200 m into fields. Farm-scale hedgerow restoration can provide pest control benefits up to 100 or 200 m into fields and multiple hedgerows around fields could enhance pest control throughout entire fields, reducing the need for chemical pest control.

“…), greater weed and insect pressure, and competition with adjacent vegetation for sunlight, water, and nutrients. Conservation buffers have been shown to have a negligible effect on adjacent crop yield (Barbour 2006;Stamps et al 2008). Furthermore, the implementation of conservation buffers in low-yielding crop margins does not simply displace a preexisting yield reduction associated with field margins (Stamps et al 2008).…”

“…Conservation buffers have been shown to have a negligible effect on adjacent crop yield (Barbour 2006;Stamps et al 2008). Furthermore, the implementation of conservation buffers in low-yielding crop margins does not simply displace a preexisting yield reduction associated with field margins (Stamps et al 2008). Barbour (2006) also found that in circumstances where yield was reduced next to a conservation buffer that the magnitude of reduction was small enough to be offset by the economic gain associated with conservation buffer payments (e.g., SRR and Signup Incentive Payment).…”

Abstract:The USDA Farm Bill conservation programs provide landowner incentives to remove less productive and environmentally sensitive lands from agricultural production and reestablish them in natural vegetation (e.g., native grasses, trees, etc.) to achieve conservation objectives. However, removal of arable land from production imposes an opportunity cost associated with loss in revenue from commodities that otherwise would have been produced. Recent Farm Bills have increasingly emphasized targeted practices to achieve specific environmental outcomes that maximize environmental benefits relative to cost. The Habitat Buffers for Upland Birds practice (CP-33) under the continuous Conservation Reserve Program is an example of a targeted conservation practice that has produced measureable outcomes (increased bobwhite and grassland bird populations) with relatively minor changes in primary land use. However, establishing conservation buffers on profitable farmland may be incompatible with the economic objectives of landowners/producers. Precision agriculture technologies provide a powerful conservation planning tool for identifying environmental and economic opportunities in agricultural systems. Precision implementation of conservation practices, such as CP-33, is the foundation of strategic conservation planning and is essential for optimization of environmental and economic benefits. Toward this end, we developed a geospatial decision support tool (Arc GIS tool) to inform this decision-making process. We illustrate the geoprocessing workflow of the tool and demonstrate the conditions under which precision implementation of conservation practices can concomitantly increase whole-field profitability and environmental services for an example farm in Mississippi.

“…The impact of the current agricultural land use change from soybean to sugarcane plantations should be prioritized for studies on biodiversity conservation as it can affect not only agricultural fields but also border areas of native vegetation [19]. In order to understand the possible changes on the patterns of distribution and abundance of biodiversity in such conditions, we should first carry out biodiversity inventories in areas where the original ecosystems of the Cerrado biome have been replaced by an agricultural landscape whose matrix is soybean.…”

Brazil has become one of the top producers and exporters of food, fibre, and bionergy in the world.The expansion of livestock and soybean production in the Amazon basin appears to be independent of the sugarcane expansion in southeastern Brazil whereas the impact of sugarcane expansion over areas of soybean plantation in previous Cerrado biome is still unknown. However, the expansion of sugarcane production in the state of São Paulo has been shown to cause an increase in the local abundance of rodents and result in the emergence of infectious diseases such as hantaviruses and leptospirosis in humans. In addition, with an increase in the use of agrochemicals there will be an increase in euthrophication of watercourses and soil pollution. Considering that São Paulo has a population of approximately 40 million people, these local impacts are relevant. Environmental law should be improved and enforced in Brazil to ensure that sugarcane production is not only economically profitable but also environmentally responsible.
