Examining New Donors in the OECD's Development Assistance Committee

Journal of International Development, EarlyView.
ABSTRACT How do emerging donors integrate into the existing international aid architecture? While the existing literature focuses largely on emerging donors from the Global South, such as Brazil, China, India and Russia, there are many emerging donors from the Global North that have joined the OECD's Development Assistance Committee (DAC)—the premier ...

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.
