We provide a synthesis of what regional scientific research networks in less developed regions of the world can do and why they might be relevant for societal decisions and practice. We do so through a focus on three regional science network initiati

National governments and research scientists may be equally concerned with issues of global environmental change, but their interests-and their timelines-are not the same. Governments are often focused on short-term effects and local impacts of globa

Global change cuts across human and natural systems. Addressing it requires interdisciplinary research across the human and natural sciences. We show that the promotion of interdisciplinarity requires more than changing the requirements of funding ca

Regional change under agricultural expansion in the Chaco of Argentina is determined by interactions of rainfall change, infrastructure development, socio-economic actions and values, and the social perceptions of change. Our study focused on adaptat

Although many studies have examined the effect of different application rates of cattle manure, swine manure, and urea fertilizer on the distribution of phosphorus (P) fractions in soil, few studies have correlated P fractions in soil with inorganic

Trees in silvopastoral systems can accumulate carbon (C) and nutrients under their canopies. Most studies measure only net changes in organic matter and nutrients without evaluating turnover of soil organic matter. Here, the change in vegetation cove
