Tourism contributes significantly to global gross domestic product, and is forecast to grow at an annual 4%, thus outpacing many other economic sectors. However, global carbon emissions related to tourism are currently not well quantified. Here, we quantify tourism-related global carbon flows between 160 countries, and their carbon footprints under origin and destination accounting perspectives.

Aerosols play an important role in climate change processes. Among the various aerosols, black carbon (BC) has been recognized as the second most important anthropogenic agent for climate change and the primary tracer for adverse health effects caused by air pollution. The increasing concentration of BC in the atmosphere has now become a matter of serious concern, especially in the high Himalayan glaciated region that has the most vulnerable ecosystem with pristine environment, rich biodiversity and pollution-free ambient air quality.

Tourism activities occurring on communal lands such as Wildlife Management Areas (WMAs) are increasing in Tanzania. This is the result of natural resources governance reforms aimed to empower communities to manage and benefit directly from resources found in their jurisdictions. This article explores the impacts of taxes imposed on tourism activities occurring on communal lands and the emerging politics of resource and revenue sharing among WMA member villages. In the process, we use empirical data gathered from two WMAs in northern Tanzania between 2006 and 2016.
