Conservation of biodiversity, improving rural livelihoods and supporting sustainable agriculture are key issues globally, but for many Pacific Island Countries (PICs) key biodiversity reserves are under considerable pressure from clearing and degradation. Rural communities are often put in a situation where clearing of forest margins is undertaken to meet demand for arable land to produce food and generate income. Forest reserves are also degraded by logging, where timber royalties are important in the absence of other sources of income for traditional landowners and communities. Therefore, agroforestry and ecologically based agriculture systems in the forest margins can help to offset reliance on forest degradation and can enhance the buffers around key reserves. Sustainable forest management and ecotourism also need to be maximised to help meet these challenges of generating income whilst maintaining or enhancing biodiversity, conserving soil and water resources.

Microplastics are widespread in the natural environment and present numerous ecological threats. While the ultimate fate of marine microplastics are not well known, it is hypothesized that the deep sea is the nal sink for this anthropogenic contaminant. This study provides a quanti cation and characterisation of microplastic pollution ingested by benthic macroinvertebrates with different feeding modes (Ophiomusium lymani, Hymenaster pellucidus and Colus jeffreysianus) and in adjacent deep water> 2200 m, in the Rockall Trough, Northeast Atlantic Ocean. Despite the remote location, microplastic bres were identi ed in deep-sea water at a concentration of 70.8 particles m 3, comparable to that in surface waters. Of the invertebrates examined (n ¼ 66), 48% ingested microplastics with quantities enumerated comparable to coastal species. The number of ingested microplastics differed signi cantly between species and generalized linear modelling identi ed that the number of microplastics ingested for a given tissue mass was related to species and not organism feeding mode or the length or overall weight of the individual. Deep-sea microplastics were visually highly degraded with surface areas more than double that of pristine particles. The identi cation of synthetic polymers with densities greater and less than sea water along with comparable quantities to the upper ocean indicates processes of vertical re-distribution.

The Asia and Pacific region is extremely vulnerable to the impacts of climate change. Unabated warming could significantly undo previous achievements of economic development and improvements of living standards. At the same time, the region has both the economic capacity and weight of influence to change the present fossil-fuel based development pathway and curb global emissions. This report sheds light on the regional implications of the latest projections of changes in climate conditions over Asia and the Pacific. The assessment concludes that, even under the Paris consensus scenario in which global warming is limited to 1.5°C to 2°C above preindustrial levels, some of the land area, ecosystems, and socioeconomic sectors will be significantly affected by climate change impacts, to which policy makers and the investment community need to adapt to. However, under a Business-As-Usual (BAU) scenario, which will cause a global mean temperature rise of over 4°C by the end of this century, the possibilities for adaptation are drastically reduced. Among others, climate change impacts such as the deterioration of the Asian “water towers”, prolonged heat waves, coastal sea-level rise and changes in rainfall patterns could disrupt ecosystem services and lead to severe effects on livelihoods which in turn would affect human health, migration dynamics and the potential for conflicts. This assessment also underlines that, for many areas vital to the region’s economy, research on the effects of climate change is still lacking.
