Forest planning and traditional knowledge in collective woodlands of Spain: The dehesa system
SIAT - Sistema de Avaliação de Terras
The purpose of this work was to adapt the MicroLEIS - Land Evaluation Information System developed in Spain to the Brazilian Southeast conditions. Twelve (12) variables were considered, as follows: A - Relief Factor: 1) Slope; B - Soil Factor: 2) Effective depth, 3) Texture, 4) Stoniness, 5) Drainage, 6) Salinity; C - Erosion Factor: 7) Erodibility, 8) Slope, 9) Vegetation density, 10) Rainfall erosivity; D - Bioclimatic Deficiency Factor: 11) Frost, 12) Available water. For each of them, the control parameters were changed, according to conditions of the soils of the State of São Paulo.
European biomass resource potential and costs
The objective of this study is to assess the European (EU27+ and Ukraine) cost and supply potential for biomass resources. Three methodological steps can be distinguished (partly based on studies explained elsewhere in this volume) (i) an evaluation of the available 'surplus' land, (ii) a modeled productivity and (iii) an economic assessment for 13 typical bioenergy crops. Results indicate that the total available land for bioenergy crop production - following a 'food first' paradigm - could amount to 900 000 km2 by 2030.
Abomasal parasites in wild sympatric cervids, red deer, Cervus elaphus and fallow deer, Dama dama, from three localities across central and western Spain: relationship to host density and park management
A survey of abomasal parasites in cervids from Central Spain was conducted at 3 sites, Quintos de Mora (Toledo), Maluéñez de Arriba (Cáceres), and La Herguijuela (Cáceres). Commonly occurring helminths belonged to 3 polymorphic species of the Ostertagiinae: Spiculopteragia asymmetrica/S. quadrispiculata, Ostertagia leptospicularis/O. kolchida, and O. drozdzi/O. ryjikovi. Trichostrongylus axei was found in very few cases. Ostertagia drozdzi/O. ryjikovi and the minor male morphotype, S. quadrispiculata, are reported for the first time in red deer from Spain.
Estimation of actual evapotranspiration from remote sensing: application in a semiarid region
The potential of remote sensing for the recommendation and monitoring of irrigation practices is irrefutable. GIS have enabled the development of operational spatio-temporal tools for monitoring agricultural activity which can overcome the uncertainty brought about by problems related to water scarcity and increasing drought events. This paper presents an operational methodology for estimating actual evapotranspiration from Landsat images, and its application in the Region of Murcia (Spain).
Assessing the influence of afforestation with Eucalyptus globulus on hydrological response from a small catchment in northwestern Spain using the HBV hydrological model
Land use change as conversion pasture to forest produces several changes on hydrological cycle. In this paper, we analyse the effects on stream discharge of afforestation of a small watershed devoted to pasture using the HBV hydrological model. Streamflow data obtained over the first 10 years after planting were employed to evaluate the capacity of HBV model to simulate hydrological behaviour of catchment after afforestation. Obtained results indicate that the estimation of streamflow was accurate as reflected by statistics (R² = 0.90, NSC = 0.89 and PBIAS = 0.34).
Bayesian Network Application to Land Suitability Classification in the Sewage Sludge Amendment of Agricultural Soils
Sewage sludge (SS) amendment of agricultural soils has recently become an issue of great interest because improvements in wastewater treatment systems have increased production of this type of waste. This practice is known to benefit soil and crops. However, the potential contamination of the environmental matrices has been rarely assessed because suitable models and data regarding the diffuse contamination of SS in agricultural fields are limited.
The MODERE Model and The Economic Analysis of Farmers’ Decisions
The MODERE, the Ministry of the Environment Irrigation Decision Model, is a simulation tool whichuses mathematical programming methods to reveal the implicit multiattribute objective function lyingbehind the observed cropping decision. The model takes different criteria such as profit maximization,risk aversion, avoidance of management complexities and so forth into account.
