Nations of the world have committed to a number of goals and targets to address the global environmental challenges humanity faces. Protected areas have for centuries been a key strategy in conservation and play a major role in addressing current challenges. The most important tool used to track progress on protected area commitments is the World Database on Protected Areas (WDPA). Periodic assessments of the world’s protected area estate show steady growth over the last two decades. However, the current method, which uses the latest version of the WDPA, does not show the true dynamic nature of protected areas over time, nor does it provide information on sites removed from the WDPA. In reality, this methodology can only show growth or remain stable. This paper presents a novel approach to assess protected area change over time using twelve temporally distinct versions of the WDPA that quantify area added, and removed, from the WDPA annually from 2004 to 2016. Results show that both the narrative of continual protected area growth and the counter-narrative of protected area removal are overly simplistic. The former because growth has been almost entirely marine and the latter because we demonstrate that some areas removed are re-protected in later years. Analysis indicates that, on average, 2.5 million km2 is added to the WDPA annually and 1.1 million km2 is removed. Reasons for the inclusion and removal of protected areas in the WDPA database are explored and discussed. To meet the 17% land coverage component of Aichi Biodiversity Target 11 by 2020, which stands at 14.7% in 2016, the world will either need to reduce the rate of protected area removal or increase the rate of protected area designation and addition to the WDPA.

Natural disasters have a significant impact in the Pacific Islands. Between 1950 and 2004, more than 200 disasters resulted in more than 1700 fatalities and losses amounting to USD 6.5 billion. Given their small populations and economies, such losses are traumatic to Pacific Island countries. Tonga, one of 52 Small Island Developing States (SIDS), is highly susceptible to the impacts of climate change and disasters due principally to its geographical, geological, and socio–economic characteristics. Climate change and natural disasters pose severe adverse threats on the environment, the people of Tonga, and their livelihoods. Scientific findings revealed that these impacts would be exacerbated by future climate change. The Government of Tonga has acknowledged these risks to the sustainable development of the country and has hence considered these issues as high priorities in its National Strategic Planning Framework. The United Nations Development Programme (UNDP) and the Australian Government Pacific Adaptation Climate Change (PACC) project have assisted to increase the resilience of the water resources management sector in Tonga and to enhance adaptive capacity of villages, communities and socio–economic activities to climate change and sea level rise (SLR). This paper, however, describes the impacts of water resources due to climate change rather than the PACC results.
