Carbon losses from deforestation and widespread degradation offset by extensive growth in African woodlands
Degradation—the loss of carbon stored in intact woodland—is very difficult to measure over large areas. Here, the authors show that carbon emissions from degradation in African woodlands greatly exceed those from deforestation, but are happening alongside widespread increases in biomass in remote areas
Synergies and trade-offs of national conservation policy and agro-forestry management over forest loss in Argentina during the last decade
One reason for the decline of natural forest is that many ecosystem services(ES) are usually not priced and values were only considered provisioning services. Argentina enacted the National Law 26,331/07, which regulates protection, enrichment, restoration, and management of native forests and its environmental services. The objective is to determine the ecological and socio-political factors that influence the dynamics of forest cover loss before and after the law implementation, and discuss the effectiveness of conservation and forest management policies. Satellite images, national ordination, forest regions maps and other variables were combined in GIS with national databases (social, agriculture, industry) to determine the evolution of potential drivers of forest changes. The main potential drivers were: (i) population growth, (ii) road density, (iii) crops area, (iv) livestock and (v) fires. Payment of incentives by government can not fully stop the deforestation but decrease the forest loss rate. New approaches must be considered to built-in flexibility actions according to local conditions and constraints, which are influenced by social and economic contexts. Thus, it is necessary to establish new regional policies associated with the factors linked to the loss of forest cover, in thesearch for sustainable management alternatives that combine economic andconservation proposals.Fil: MartÃnez Pastur, Guillermo José.

An assessment of the metabolic profile implied by agricultural change in two rural communities in the North of Argentina
The soy expansion model in Argentina generates structural changes in traditional lifestyles, which can be associated with different biophysical and socioeconomic impacts. To explore this issue, we apply an innovative method for integrated assessment-the multi-scale integrated analysis of societal and ecosystem metabolism framework-to characterize two communities in the Chaco Region, Province of Formosa, North of Argentina. These communities have recently experienced the expansion of soy production, altering their economic activity, energy consumption patterns, land use and human time allocation. The integrated characterization presented in the paper illustrates the differences (biophysical, socioeconomic and historical) between the two communities that can be associated with different responses. The analysis of the factors behind these differences has important policy implications for the sustainable development of local communities in the area
