Communal forests are a unique land tenure system and comprise a singular legal category in Galicia. Their persistence over time demonstrates that this community-owned resource has overcome the “tragedy of the commons”, showing their capability to successfully develop self-governing institutions. However, communal forests have rarely been studied through the lens of economics. This minimizes the opportunity to explore to what extent communities of communal forests might be a driving force of general well-being, citizen empowerment, equity, employment, and local development.
Greenhouse Gas Emissions from Forest Soils Reduced by Straw Biochar and Nitrapyrin Applications
Forestlands are widely distributed in the dominantly agricultural landscape in western Canada, and they play important ecological functions; such forestlands (e.g., shelterbelts) accumulate soil organic matter and may receive a substantial amount of nitrogen in the form of surface and subsurface runoff from adjacent croplands and become a significant source of emissions of greenhouse gases (GHGs) such as CO2, N2O, and CH4. Biochar and nitrapyrin applications could potentially mitigate GHG emissions, but their co-application in forest soils has not been studied.
Vegetation Degradation of Guanshan Grassland Suppresses the Microbial Biomass and Activity of Soil
Changes in vegetation influence the function of grassland ecosystems. A degradation of the vegetation type has been found from high to low altitudes in Guanshan grassland in the order of forest grassland (FG) < shrub grassland (SG) < herb grassland (HG). However, there is poor information regarding the effect of vegetation degradation on soil microbes in Guanshan grassland. Therefore, our study evaluated the impact of vegetation degradation on the microbial parameters of soil, as well as the mechanisms responsible for these variations.
Changes in Vegetation of Flooded Savannas Subject to Cattle Grazing and Fire in Plains of Colombia
Cattle grazing and fire are common types of management on natural ecosystems, generating several threats to the conservation of native vegetation (e.g., changes in species richness, cover, and abundance, mainly of bovine-palatable species). In this work, we analysed the response of the structure and composition of vegetation managed with different cattle stocking rates and fire in the savanna ecosystems of Colombia. The study was located in the eastern area of the Llanos region, where savannas were subjected to grazing and burning.
Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates
We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops.
