ABSTRACT Deforestation and land-use change are accelerating in the Congo Basin and elsewhere in the tropics affecting the soil-atmosphere exchange of greenhouse gases (GHG). There is a lack of data from Central Africa. We quantified CO2, CH4, and N2O fluxes at the soil-atmosphere interface in a secondary forest, a cocoa agroforest, and an unfertilized cropland in a typical central African forest transition

ABSTRACT As the primary alternative to ozone-depleting refrigerants, hydrofluorocarbons (HFCs) have increased in use and emissions in the United States. This increase, and a large portion of total U.S. HFC consumption, is expected due to the use of HFCs in residential air conditioning (RAC). The RAC market primarily relied upon chlorodifluoromethane, a hydrochlorofluorocarbon (HCFC) known as HCFC-22

ABSTRACT Statistical relationships between surface ozone (O3) concentration, precursor species and meteorological conditions in continental South Africa were examined from data obtained from measurement stations in north-eastern South Africa. Three multivariate statistical methods were applied in the investigation, i.e. multiple linear regression (MLR), principal component analysis (PCA) and –regression

ABSTRACT In the last decade, the debate on the governance of water, energy, and food (WEF) has intensified, spurring the emergence of the term “nexus governance.” In general, the reduction of trade-offs and construction of synergies between WEF have been placed on the scientific, political, and economic agenda. However, although increasingly used, it is difficult to find a clear meaning and definition

ABSTRACT This paper examines the making of urban sustainable food provisioning through the case of Barcelona. Barcelona is seeking to develop a more sustainable food system. It aims to green its municipal food markets by reducing the distances from which the food is sourced from. This has been labelled by the city of Barcelona as “proximity food”. We shed light on how, and to what extent, proximity
