The geography of islands The geography of islands
Islands come in all shapes, sizes and types, from tiny rocky outcrops, to enormous continental landmasses. The true number of islands distributed in the planet’s seas and oceans is still elusive. Recent efforts bolstered by an abundance of detailed satellite imagery and the sophistication of geographic information systems (GIS) are bringing real answers to those questions closer than...

Global islands Global islands
A new map of global islands at a high spatial resolution (30 m) has been produced from a semi-automated interpretation of 2014 satellite imagery. The data are available in the public domain. The islands were classified by size into continental mainlands (5), big islands > 1 km2 (21,818), and small islands ≤ 1 km2 (318,868). The new high-resolution islands data are intended to support...

An assessment of the representation of ecosystems in global protected areas using new maps of World Climate Regions and World Ecosystems An assessment of the representation of ecosystems in global protected areas using new maps of World Climate Regions and World Ecosystems
Representation of ecosystems in protected area networks and conservation strategies is a core principle of global conservation priority setting approaches and a commitment in Aichi Target 11 of the Convention on Biological Diversity. The 2030 Sustainable Development Goals (SDGs) explicitly call for the conservation of terrestrial, freshwater, and marine ecosystems. Accurate ecosystem...

The Islands of Oceania – Political geography, biogeography, and terrestrial ecosystems The Islands of Oceania – Political geography, biogeography, and terrestrial ecosystems
Humans are dependent upon ecosystems for the production of goods and services necessary for their well-being (Daily, 1997). As the service provider units (SPUs) for these benefits of nature (Anderson et al., 2015), ecosystems need to be managed in a way that maximizes their persistence on the planet. Part of that management effort includes knowing a) what the ecosystem types are, b)...
