A bioeconomic model of carbon trading within an Australian grazing enterprise AgEcon
Gowen, Rebecca; Rolfe, John; Donaghy, Peter.
The Carbon Farming Initiative (CFI) and other carbon trading programs have been promoted as alternative sources of income for agricultural producers, particularly those on marginal land. This paper presents the results of a bioeconomic model developed to compare the relative returns from a beef enterprise against changing regrowth management practices to sequester additional carbon and sell carbon offsets. The model is constructed based on a 1000 hectare parcel of land in Central Queensland and is calculated for two landtypes; Brigalow and Eucalypt. Assuming zero transaction costs and a 20 year contract period, a carbon-cattle enterprise has higher returns that a cattle-only enterprise at relatively low carbon prices for both land types. However, results...

Above and Belowground Biomass Characteristics of Rhizoma Peanut Entries and Their Relationship with Soil C and N. Repositório Alice
SILVA, L. S.; SOLLENBERGER, L. E.; COOLEY, K. D.; KOHMANN, M. M.; ARYAL, P.; PEDREIRA, B. C. e; PEDROSO, G. B.; SILVEIRA, M. L.; DUBEUX JÚNIOR, J. C. B..
In forage systems, soil C and N are affected by many factors including above- and belowground biomass, root exudation, defoliation management, and tissue turnover dynamics. There is need to understand the main drivers of soil C and N accumulation under perennial forages, especially those factors associated with differences in growth and canopy characteristics. The objective was to determine soil C and N status and their relationship with above- and belowground characteristics of six rhizoma peanut (RP, Arachis glabrata) entries. Treatments were Apalachee, Chico, Ecoturf, Ona33, Peace, and Tito RP arranged in four replicates of a randomized complete block design. Stands were planted in 2010 and harvested twice per year after establishment. The area was...

Accumulation des sels nutritifs dans un sédiment lagunaire et environnement hydrodynamique ArchiMer
Gomez, E; Millet, B; Picot, B.
The Mejean-Perols Lagoon is situated on the French Mediterranean coast. It is a small (747 ha) and shallow (70 cm) lagoon. Some treated effluent from Montpellier flows into this hypereutrophic lagoon. The cartography of C, N and P concentrations in the sediment was studied based on 35 bottom samples. The nitrogen and organic carbon concentrations were more or less homogeneous, the highest concentrations being found in the middle of the lagoon. The phosphate was principally bound onto the sediment in the west zone. The observed distribution was independent of grain size, the distribution of which was rather homogeneous. In this lagoon water circulation is wind induced. Four different water flow structures were observed, as functions of the prevailing winds...

Afforestation to increase the provision of ecosystem services: economic implications for Ukraine and beyond AgEcon
Nijnik, Maria; Oskam, Arie J.; Nijnik, Albert.
This paper analyses costs and benefits of planting trees on marginal lands across forestry zones in Ukraine with the purpose of using them for timber production, erosion prevention and climate change mitigation. The research reveals that establishment of new forests to increase timber production and alleviate soil erosion is economically and environmentally justified in some regions. Incorporating the effects of afforestation through on climate change mitigation increases social benefits.

Aggregate Stability in Soil with Humic and Histic Horizons in a Toposequence under Araucaria Forest Rev. Bras. Ciênc. Solo
Hanke,Daniel; Dick,Deborah Pinheiro.
ABSTRACT Aggregate stability is one of the most important factors in soil conservation and maintenance of soil environmental functions. The objective of this study was to investigate the aggregate stability mechanisms related to chemical composition of organic matter in soil profiles with humic and histic horizons in a toposequence under Araucaria moist forest in southern Brazil. The soils sampled were classified as Humic Hapludox (highest position), Fluvaquentic Humaquepts (lowest slope position), and Typic Haplosaprists (floodplain). The C and N contents were determined in bulk soil samples. The chemical composition of soil organic matter was evaluated by infrared spectroscopy. Aggregate stability was determined by applying increasing levels of...

Allocation du carbone et métabolisme azoté chez l'haptophyte Tisochrysis lutea ArchiMer
Garnier, Matthieu.
The aim of this thesis is to improve knowledge on mechanisms involved in the response to nitrogen limitation and in lipid accumulation in the microalgae haptophyte Tisochrysis lutea. The wild type strain and a lipid accumulating mutant strain were grown under different nitrogen limitation and starvation and analyzed by functional genomics. Four genes of high-affinity nitrate/nitrite transporter (Nrt2) were identified and characterized to reveal the mechanisms involved in mineral absorption in this species. Transcriptomes of both strains were sequenced and proteins affected by nitrogen starvation and differentially expressed between the two strains were identified. We so identified the functions regulated by nitrogen deficiency and potentially involved in...

Allometric equations for estimating tree biomass in restored mixed-species Atlantic Forest stands. Repositório Alice
NOGUEIRA JUNIOR, L. R.; ENGEL, V. L.; PARROTTA, J. A.; MELO, A. C. G. de; RE, D. S..
Restoration of Atlantic Forests is receiving increasing attention because of its role in both biodiversity conservation and carbon sequestration for global climate change mitigation. This study was carried out in an Atlantic Forest restoration project in the south-central region of Sã o Paulo State ??Brazil to develop allometric equations to estimate tree biomass of indigenous tree species in mixed plantations. Above and below-ground biomass (AGB and BGB, respectively), stem diameter (DBH: diameter at 1.3 m height), tree height (H: total height) and specific wood density (WD) were measured for 60 trees of 19 species. Different biomass equations (linear and nonlinear-transformed) were adjusted to estimate AGB and BGB as a function of DBH, H and...

Allometric models for estimating the phytomass of a secondary Atlantic Forest area of southeastern Brazil Biota Neotropica
Burger,Déborah Moreira; Delitti,Welington Braz Carvalho.
The purpose of this study was to develop and validate equations to estimate the aboveground phytomass of a 30 years old plot of Atlantic Forest. In two plots of 100 m², a total of 82 trees were cut down at ground level. For each tree, height and diameter were measured. Leaves and woody material were separated in order to determine their fresh weights in field conditions. Samples of each fraction were oven dried at 80 °C to constant weight to determine their dry weight. Tree data were divided into two random samples. One sample was used for the development of the regression equations, and the other for validation. The models were developed using single linear regression analysis, where the dependent variable was the dry mass, and the independent variables...

Almacenamiento de carbono en bosques manejados de pinus patula: Estimación mediante percepción remota Colegio de Postgraduados
Aguirre Salado, Carlos Arturo.
Se presenta la metodología y los resultados obtenidos sobre estimación de almacenamiento de carbono mediante técnicas de percepción remota en bosques manejados de Pinus patula en Zacualtipán, Hidalgo, México; la cual surge como una necesidad de monitoreo de los recursos forestales a partir de los compromisos adquiridos por México en el Protocolo de Kyoto para aminorar el inminente cambio climático causado por los denominados gases invernadero (CO2). En esta tesis se estudia principalmente el carbono (CHA) (Mg/ha) aunque preliminarmente resulta necesaria la cuantificación de biomasa (BHA) (Mg/ha). De manera paralela también se estudian algunos parámetros forestales de densidad como índice de área foliar (IAF) (m2/ m2), cobertura arbórea (COB) (%), área...

Amazon Forest maintenance as a source of environmental services Anais da ABC (AABC)
Fearnside,Philip M..
Amazonian forest produces environmental services such as maintenance of biodiversity, water cycling and carbon stocks. These services have a much greater value to human society than do the timber, beef and other products that are obtained by destroying the forest. Yet institutional mechanisms are still lacking to transform the value of the standing forest into the foundation of an economy based on maintaining rather than destroying this ecosystem. Forest management for commodities such as timber and non-timber forest products faces severe limitations and inherent contradictions unless income is supplemented based on environmenta lservices. Amazon forest is threatened by deforestation, logging, forest fires and climate change. Measures to avoid...

Forest degradation is broadly defined as a reduction in the capacity of a forest to produce ecosystem services such as carbon storage and wood products as a result of anthropogenic and environmental changes. The main causes of degradation include unsustainable logging, agriculture, invasive species, fire, fuelwood gathering, and livestock grazing. Forest degradation is widespread and has become an important consideration in global policy processes that deal with biodiversity, climate change, and forest management. There is, however, no generally recognized way to identify a degraded forest because perceptions of forest degradation vary depending on the cause, the particular goods or services of interest, and the temporal and spatial scales considered....

Bacteria and phytoplankton production rates in eight river stretches of the middle Rio Doce hidrographic basin (southeast Brazil) BABT
Petrucio,Mauricio Mello; Barbosa,Francisco Antônio R.; Thomaz,Sidinei Magela.
Measurements of bacterial secondary production (BSP), together with primary phytoplanktonic production (PPP) were conducted during dry and rainy seasons, in eight rivers of different orders submitted to different degrees of human impacts (different trophic degree). We aimed to determine and compare the importance of BSP and PPP in carbon fixation in these different lotic ecosystems. Our results showed that the Ipanema River was the most modified system by anthropogenic effluents inputs. These inputs altered the trophic degree and BSP rates of these streams and rivers.
