The technique of eddy correlation was used to measure the net ecosystem exchange over a woodland savanna (Cerrado Sensu stricto) site (Gleba Pé de Gigante) in southeast Brazil. The data set included measurements of climatological variables and soil respiration using static soil chambers. Data were collected during the period from 10 October 2000 to 30 March 2002. Measured soil respiration showed average values of 4.8 molCO2 m-2s-1 year round. Its seasonal differences varied from 2 to 8 molCO2 m-2s-1 (Q10 = 4.9) during the dry (April to August) and wet season, respectively, and was concurrent with soil temperature and moisture variability. The net ecosystem CO2 flux (NEE) variability is controlled by solar radiation, temperature and air humidity on diel... |

Payment for ecosystem services (PES) is a market-based approach to environmental management that compensates land stewards for ecosystem conservation and restoration. Because low-income households and communities control much of the ecologically sensitive land in developing countries, they potentially stand to gain from PES, as environmentally responsible stewardship is assigned a value by various actors in society. To date, however, instances of PES benefiting the poor have been limited mainly to specific localities, small-scale projects, and a handful of broader government programs. We analyze the size, characteristics, and trends of PES to evaluate its future potential to benefit low-income land stewards in developing countries. We estimate that by the... |

Apresenta-se uma ferramenta (kit) para avaliação simplificada de SE em agroecossistemas, que está em desenvolvimento por pesquisadores da Embrapa Solos nos últimos anos. A ferramenta agrega um conjunto de protocolos e instrumentos, bem como um manual com orientações de uso para a avaliação simplificada dos serviços ecossistêmicos, a saber: controle à erosão, provisão e regulação hídrica, sequestro de carbono, regulação da fertilidade e avaliação da polinização. |

Grasslands are among the largest ecosystems and cover around 3.5 billion-hectare (ha) area, representing 26 percent of the world land area and 70 percent of the world agricultural area. These grassland soils contain about 20 percent of the world?s soil organic carbon (SOC) stocks. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. Grasslands that are self-seeded are often defined as natural or native grasslands. These grasslands are predominated by grasses, grass-like plants, forbs, or shrubs suitable for grazing or browsing. They are defined as rangelands when natural (native) or grazed, and defined as pastures when forage is managed by seeding, mowing (i.e. for hay, silage, renewable energy... |

Abstract The objective of this work was to evaluate the physical quality of an Oxisol under no-tillage subjected to different crop rotations and crop sequences. The experiment was carried out in a clayey Oxisol, during six years, in a randomized complete block design, with strip plots and three replicates. The following physical indicators of soil quality were evaluated: soil density and carbon content, as well as mean weight diameter and tensile strength of aggregates. Treatments consisted of three summer crop rotations - corn/corn (Zea mays), soybean/soybean (Glycine max), and soybean/corn - and of seven second crops (crop sequences) - corn, sunflower (Helianthus annuus), oilseed radish (Raphanus sativus), pearl millet (Pennisetum americanum), pigeon pea... |

Arctostaphylos pungens HBK is a dominant species with increasing abundance and distribution in chaparral ecosystems as a result of range management and, possibly, changes in climate. The value of this species for carbon (C) sequestration is unknown, and the standard 50% C out of total tree biomass is used as an approximate value. In this study, we aim to determine the C concentration of the primary components of A. pungens. The total C expressed as a percentage of biomass was determined with a Solids TOC Analyzer. We found the C concentration to vary among components. Leaves exhibited the highest C concentration (51.70%). Roots (46.11%), stems (47.30%), fruits (47.89%) and twigs (48.40%) had similar C concentration. These results provided superior... |

Carbon sequestration is a temporal process in which carbon is continuously being stored/released over time. Different methods of carbon accounting can be used to account for this temporal nature, including annual average carbon, annualized carbon, and ton-year carbon. In this paper, starting by exposing the underlying connections among these methods, we examine how the comparisons of sequestration projects are affected by these methods and the major factors affecting them. We explore the empirical implications for carbon sequestration policies by applying these accounting methods to the Upper Mississippi River Basin, a large and important agriculture area in the United States. We find that the differences are significant in terms of the location of land... |

With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers and landholders in rural Australia have increased opportunities to participate in the market. This includes the adoption of land-use change to sequester additional carbon in exchange for carbon credits and the production of a renewable energy source (biofuels). However, these land-use changes compete with existing farm enterprises and may contain significant transaction costs. Therefore it is necessary for the institutional arrangements to provide adequate incentives for landholders to adopt these land-use changes. This paper examines the potential supply of these land-use changes for climate mitigation from landholders in a northern NSW catchment. These results... |
