“…From an economic perspective, the willingness of producers to supply ecosystem services depends on whether provision of these services increases profits or reduces risks at the farm level. Many ecosystem services do not have an effect on profits or risks at the farm level, because many effects are driven by processes at a larger spatial scale than the farm level, occur primarily off-farm and (or) may be public goods where markets do not fully capture the value of these services [159][160][161] . For example, the spatial pattern of land cover across broad geographic regions can have a large effect on the population and distribution of wildlife species.…”

Conservation agricultural systems rely on three principles to enhance ecosystem services: (1) minimizing soil disturbance, (2) maximizing soil surface cover and (3) stimulating biological activity. In this paper, we explore the concept of diversity and its role in maximizing ecosystem services from managed grasslands and integrated agricultural systems (i.e., integrated crop-livestock-forage systems) at the field and farm level. We also examine trade-offs that may be involved in realizing greater ecosystem services. Previous research on livestock production systems, particularly in pastureland, has shown improvements in herbage productivity and reduced weed invasion with increased forage diversity but little response in terms of animal production. Managing forage diversity in pastureland requires new tools to guide the selection and placement of plant mixtures across a farm according to site suitability and the goals of the producer. Integrated agricultural systems embrace the concept of dynamic cropping systems, which incorporates a long-term strategy of annual crop sequencing that optimizes crop and soil use options to attain production, economic and resource conservation goals by using sound ecological management principles. Integrating dynamic cropping systems with livestock production increases the complexity of management, but also creates synergies among system components that may improve resilience and sustainability while fulfilling multiple ecosystem functions. Diversified conservation agricultural systems can sustain crop and livestock production and provide additional ecosystem services such as soil C storage, efficient nutrient cycling and conservation of biodiversity.

“…It can also be used to communicate the environmental implications of existing distributions of social and economic activities (Bockstael, 1996;Eade and Moran, 1996;Deacon et al, 1998;Irwin and Geoghegan, 2001;Bateman et al, 2002;Lant et al, 2005;Sanchirico and Wilen, 2005;Hein et al, 2006).

Sustainable natural resource management requires inputs from both the natural and the social sciences. Since natural and social systems are inter-related and inter-dependent, it is essential that these data can be integrated within a given analysis, which requires that they are spatially compatible. However, existing environmental and socio-economic monitoring networks tend to observe, collect and report socio-economic and biophysical data separately; with the result that much of these data are spatially incompatible, adding to the complexity of objective and consistent resource management. We present an approach for overcoming spatial incompatibilities between socio-economic and biophysical data; based on a meta-modelling approach using Geographical Information Systems and an application of a water-use simulation model. The method is developed and applied to the irrigation agriculture sector in the Inkomati Water Management Area in South Africa. Agricultural 2 census data, which is measured on a magisterial district scale, is integrated with georeferenced land cover data, which is independent of political boundaries. This allows us to increase the resolution at which data on the economic value derived from irrigation water is presented, from coarse magisterial district scale to a finer (49km 2 ) 'meso-zone' scale, enabling more efficient allocations of irrigation water within magisterial districts.

“…O programa CRP utiliza a Universal Soil Loss Equation (USLE) (Wischmeier & Smith, 1978) para estimativa da perda de solo e prioriza sua aplicação nas áreas classificadas como Altamente Erodíveis (AE), definidas por meio da razão entre o potencial natural de erosão e os valores de tolerância à perda de solo (FSA, 1985;Renschler & Harbor, 2002;Lant et al, 2005;USDA-NRCS, 2006). Essa relação também pode ser denominada de Risco Natural de Erosão -RNE (Basic et al, 2004;Boellstorff & Benito, 2005;Schiettecatte et al, 2008;Oliveira et al, 2011).…”

RESUMOO programa brasileiro de serviços ambientais, denominado "Produtor de Água", apoia-se em incentivos financeiros proporcionais à redução da erosão advinda da implantação voluntária de projetos de conservação do solo por parte de produtores rurais. No entanto, esse programa não constitui restrições preestabelecidas de elegibilidade de áreas de aplicação ou de propostas de conservação. Assim, no sentido de contribuir para a evolução metodológica desse programa, propõe-se uma nova abordagem deste, analisando-se, essencialmente, duas adaptações: introdução de critério de elegibilidade; e utilização da aptidão agrícola para indicação de propostas de uso intensivo e conservação do solo. Para isso, tomou-se por base uma bacia hidrográfica rural próxima ao Pantanal brasileiro, em Terenos, MS. O novo critério de elegibilidade foi baseado no Risco Natural de Erosão (razão entre o potencial natural de erosão e a tolerância à perda de solo). As propostas de ocupação do solo, por sua vez, foram definidas a partir de mapa de aptidão agrícola predefinido. O estudo revela que o novo critério de elegibilidade foi capaz de contemplar somente cerca de 40 % da área de estudo. A aplicação da classificação de aptidão agrícola nessa parcela reduziu drasticamente as alternativas de uso intensivo do solo, direcionando-as, em grande parte, para a atividade pecuária. A análise das duas propostas de inovação do programa "Produtor de Água" permite inferir quanto à potencialidade delas na formação de estratégias de aplicação do programa, além de promover uso mais eficiente dos recursos financeiros destinados ao pagamento por serviços ambientais no contexto brasileiro.Termos de indexação: uso sustentável do solo, conservação do solo, políticas agroambientais.(1) Parte da Dissertação de Mestrado do primeiro autor. Recebido para publicação em setembro de 2010 e aprovado em março de 2011.
