Papua New Guinea (PNG) stands at a critical moment in its development. With Gross Domestic Product (GDP) growth of over 20 per cent expected for 2015, following the start of production from the massive PNG Liquified Natural Gas (LNG) project, the country has a unique opportunity to leverage significant sustainable and equitable improvements in levels of health, education, income and other elements of inclusive human development.
Changing temperature and precipitation pattern and increasing concentrations of atmospheric CO2 are likely to drive significant modifications in natural and modified forests. Our review is focused on recent publications that discuss the changes in commercial forestry, excluding the ecosystem functions of forests and nontimber forest products. We concentrate on potential direct and indirect impacts of climate change on forest industry, the projections of future trends in commercial forestry, the possible role of biofuels, and changes in supply and demand.
There is growing evidence that global climate change is significantly altering forest ecosystems, and will continue to do so in the future. Changes in mean climate and climate extremes such as drought, storms, cyclones and wildfires can fundamentally alter species distribution, composition, phenology, and forest structure. This study reviewed the available evidence of climate change impacts on tropical forests. We selected 85 studies based on two selection criterias and recorded the impacts of climate change on different areas of tropicalforests.
Australia has a highly diverse and variable climate and its forests evolved under a relatively high level of climatic variation. However, human-induced changes in climate are likely to exceed historical ranges of variability and rates of change, and have effects on forests well beyond the experience of forest managers. These conditions will require implementation of management practices appropriate to a changing climate.
Nearly 4 % of the world’s forests are plantations, established to provide a variety of ecosystem services, principally timber and other wood products. In addition to such services, plantation forests provide direct and indirect benefits to biodiversity via the provision of forest habitat for a wide range of species, and by reducing negative impacts on natural forests by offsetting the need to extract resources. There is compelling evidence that climate change is directly affecting biodiversity in forests throughout the world.
Forest plantations are a possible way of increasing forest productivity in temperate and tropical forests, and therefore also increasing above- and belowground carbon pools. In the context of climate change, monospecific plantations might become an alternative to mitigate global warming; however, their contribution to the structural complexity, complementarity, and biodiversity of forests has not been addressed.
Tropical reforestation (TR) has been highlighted as an important intervention for climate change mitigation because of its carbon storage potential. TR can also play other frequently overlooked, but significant, roles in helping society and ecosystems adapt to climate variability and change. For example, reforestation can ameliorate climate-associated impacts of altered hydrological cycles in watersheds, protect coastal areas from increased storms, and provide habitat to reduce the probability of species’ extinctions under a changing climate.
We present a review and analysis of the conservation status and International Union for Conservation of Nature (IUCN) threat categories of all 360 currently recognized species of extant and recently extinct turtles and tortoises (Order Testudines). Our analysis is based on the 2018 IUCN Red List status of 251 listed species, augmented by provisional Red List assessments by the IUCN Tortoise and Freshwater Turtle Specialist Group (TFTSG) of 109 currently unlisted species of tortoises and freshwater turtles, as well as re-assessments of several outdated IUCN Red
Given the economic and cultural dependence on the marine environment in Oceania and a rapidly expanding human population, many marine species populations are in decline and may be vulnerable to extinction from a number of local and regional threats.
This is an economic evaluation of the compensation to which Papua New Guinea’s customary landholders -
wrongly dispossessed through Special Agricultural Business Leases (SABL) - might be entitled if they successfully
sued the government. The evaluation involves the calculation of commercial loss but also, and probably more importantly, economic equivalent value loss. The framework identifies the relevant heads of value (not just priced
transactions) and demonstrates appropriate methods for valuation. It does not pretend to be a price calculator
On the 25th of January this year, Papua New Guinea’s Post Courier newspaper reported that the National Court had just overturned a decision made by a provincial land court magistrate in 2006. The decision in question was meant to
resolve a dispute between two members of a Huli clan about the ownership of land in the Moran petroleum development licence area, which is one of eight licence areas that now form part of the PNG Liquefied Natural Gas (LNG) project. But it seems that the magistrate ‘mistakenly’ granted one of the disputing parties.
In recent years, one of the oldest asset classes in investment – land – has become an issue of international concern and scrutiny. Land acquisitions are being announced at a breakneck pace1 as companies look to produce more food, wood fiber, minerals and energy.
Papua New Guinea is linguistically and culturally the most diverse country in the world. PNG’s languages, as the repositories of ethnobiological knowledge and culture, play a crucial role in biodiversity conservation. The current trends in cultural, social and economic changes in PNG are threatening the survival of languages and ethnobiological knowledge, but there are very limited studies done to assess the suspected decline of indigenous language and ethnobiological knowledge of Papua New Guinea.
This study evaluates the factors affecting community mangrove restoration at nine sites in eight ifferent coastal villages of Manus Island, Papua New Guinea. Between June 2012 and April 2014, more than 8,400 mangrove seedlings of five species were planted on both restoration sites and sites with no history of mangroves. The timing of the plantings was uncontrolled, and some communities continued haphazard planting between the two periods.
