“…beneficial arthropods) within an agrosystem are, however, highly dependent on the area's plant community richness (Altieri, 1999), even if they may vary within the cultivated field, also because plant species richness decreases from the edge to the centre of the field (Debras et al, 2008;Thomson & Hoffmann, 2009;Poggio et al, 2013;Molina et al, 2014). The species richness (plants and arthropods) and abundance that normally are observed in the edges occur mainly in more stable conditions with richer resources within semi-natural habitats, rather than in productive fields (Marshall & Moonen, 2002).…”

In areas of intensive agriculture, wild plant species are confined to field margins, thus they play a role in protecting biodiversity. The aim of the present study was to assess plant diversity in an area of intensive viticulture and to evaluate, for the first time, the impact of field margins on vineyard flora biodiversity. The study was conducted in North-West Italy, were five categories of floristic lists in vineyard-margin pairs were sampled and compared. Five margins were identified: grass-covered (A) and bare (B) headlands, small (C) and wide (D) woodlands, and shrub and herbaceous (E) areas. Two hundred and fifty-two taxa were found, although only 19 were widespread. Differences among categories emerged, highlighting the high floristic complexity of the sites surrounded by wide wooded areas (D). The findings suggest an influence of margin size, in addition to margin type, on the floristic richness of the vineyard. Moreover, an inverse relationship between species richness and both the presence of Poaceae and the degree of soil grass coverage emerged. Enhancing biodiversity, at landscape and field level, by the appropriate management of cover crops and ecological infrastructures, within and around vineyards, could be a strategy in sustainable viticulture. The increase in plant species richness is not an end in itself, but it might help to promote biodiversity at different trophic levels.

“…In our study, the irrigation canal and drainage presented intermediate richness (Figure 2), but the turn area, which was equivalent to field edges in Poggio et al (2013) and José-María et al (2010), consistently exhibited the same weed richness as the border. This is particularly interesting, because our original hypothesis was that weed diversity would be negatively affected by the intensity of the disturbance caused by agricultural management (Hawes et al 2010).…”

“…However, studies in subtropical and several temperate regions have identified weed diversity levels similar to our results. For instance, sampling at a larger scale (approximately 7,000 km 2 ) in an area with intensive annual crop production including maize, soybean, and winter wheat in the Rolling Pampa region in Argentina, Poggio et al (2013) identified 143 arable plant species. Gaba et al (2010) reported 135 weed species in winter wheat fields in central western France, while Cordeau et al (2012) and Trichard et al (2013) reported 101 and 93 weed species, respectively, in agricultural fields in central and eastern France.…”

Weed diversity, structure, and distribution within and outside agricultural fields affect not only ecological processes but also weed management strategies. We studied how areas managed differently within and outside the field determine weed communities in a sugarcane cropping system in the dry tropics of Costa Rica. A total of 120 weed species were detected, which was similar to surveys conducted in subtropical and temperate conditions. Weed species richness was highest in undisturbed field borders and lowest in rows and furrows. The area where tractors turn within the field (turn area) had similar richness compared with the borders, despite being one of the most disturbed management areas studied. The most predominant weed species were divided between generalists and species that exhibited clear preferences for management area or soil texture. Soil texture was more important for determining weed community structure than management area when considering weed species affecting weed control decisions. The results indicated that disturbance in the management area and, especially, weed control practices are critical factors affecting weed diversity, but availability of resources for weed growth such as nutrients, soil moisture, and light can mitigate some of the limitations imposed by weed control on weed diversity, especially in the turn area. Differences in weed communities between management areas within fields indicated the existence of conditions that favor key weed species, and this information can be used to anticipate their population growth and help determine when and where more intensive control should be implemented. Nomenclature: sugarcane, Saccharum officinarum L.

In this chapter, requirements for and lessons learnt from assessing the impact of land use and land cover change (LULCC) on the provision of hydrological ecosystem functions (ESF) and services (ESS) are demonstrated based on selected case studies. First, potentials, limits and transferability of a detailed land classifi cation scheme developed for Germany are explored. Second, an approach how to make use of landscape metrics to correct the assessment of ESF and ESS provision in LULCC impact assessment is presented to better account for land-use pattern heterogeneity. Third, the potential of Hydrological Response Units (HRU) to bridge scale-related discrepancies between modeling, assessment and decision units is discused. Finally, a conceptual framework approach is suggested that builds on the HRU concept and merges the latter with a cellular automaton based LULCC impact assessment framework.
