| The trade-off between economically critical provisioning services and environmentally sustaining supporting services often seems absolute. Yet, when land use is inefficient, managers may be able to increase provision of both economically and ecologically sustaining services. To explore such sustainable "win-win" outcomes, I present a model of predicted trade-offs of provisioning and supporting services on smallholder farms in eastern Paraguay. The spatially implicit model simulates smallholder parcels as mosaics of subsistence agriculture, cattle pasture, eucalyptus plantations, and/or natural forest cover, and predicts provisioning and supporting service supply depending on the relative abundance of each land-use type per parcel. I represent provisioning... |

| The landscape of Mengsong, southwest China, was biologically diverse until recently due to historical biogeographical processes overlain by the swidden-cultivation practices of the Hani who migrated there several centuries ago. Our research sought to understand how the Hani adjusted their livelihoods to new policies, markets, and technologies, and the consequences for biodiversity conservation. We combined landscape, plot, and household surveys, interviews, and reviews of secondary documents, to reconstruct the major changes and responses to challenges in the social–ecological system over previous decades. Significant changes from closed to open canopy of secondary-forest vegetation took place between 1965–1993 and from open-canopy... |

| A generally used term for easy marketable commodities usually with high prices is cash crops As a result of it these commodities are produced by many developing and especially least developed countries (LDC). These crops have witnessed fluctuation in prices during the last decade. We can suppose that these products would be the domain of developing countries nevertheless the opposite is true. Vanilla is a very good example of those products especially because just very few producers exist. We can suppose that vanilla trade would be the sphere of very few producers and beside that the agents would deal mostly with the demand site on the international market. However, the international vanilla market shows slight differences. Nevertheless, it can be grown... |

| We investigate the impacts of coffee and cotton production on land management and land degradation in Uganda, based on a survey of 851 households and soil measurements in six major agro-ecological zones, using matching and multivariate regression methods. The impacts of cash crop production vary by agro-ecological zones and cropping system. In coffee producing zones, use of organic inputs is most common on plots growing coffee with other crops (mainly bananas), and least common on mono-cropped coffee. Both mono-cropped coffee and mixed coffee plots have lower soil erosion than other plots in coffee producing zones because of greater soil cover. Potassium depletion is much greater on mixed banana-coffee plots. In the cotton production zone, few land... |

| Abstract Abstract: Successive applications of copper fungicides on vines have resulted in increased copper content in vineyard soils over the years. This high copper content has affected the growth of young vines in eradicated vineyards. Thus, the cultivation of annual species for a few years is an alternative to copper phytostabilization, because it would be a good way to decrease copper availability to plants. The aim of this study was to evaluate the physiological responses of different soybean cultivars to copper concentration increase. Four different soybean cultivars were grown under three copper concentrations: 0.5, 20 and 40 μM in nutrient solution. The main outcomes of this study were: i) Cultivar M 6410 IPRO recorded the highest photosynthetic... |
