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.

While invasive species eradications are at the forefront of biodiversity conservation, ant eradication failures are common. We reviewed ant eradications worldwide to assess the practice and identify knowledge gaps and challenges. We documented 316 eradication campaigns targeting 11 species, with most occurring in Australia covering small areas (b10 ha). Yellow crazy ant was targeted most frequently, while the bigheaded ant has been eradicated most often. Of the eradications with known outcomes, 144 campaigns were successful, totaling approximately 9500 ha, of which 8300 ha were from a single campaign that has since been partially re-invaded. Three active ingredients, often in combination, are most commonly used: fipronil, hydramethylnon, and juvenile hormone mimics. Active ingredient, bait, and method varied considerablywith respect to species targeted,which made assessing factors of eradication success challenging. We did, however, detect effects by active ingredient, number of treatments, and method on eradication success. Implementation costs increased with treatment area, and median costs were high compared to invasive mammal eradications. Ant eradications are in a phase of increased research and development, and a logical next step for practitioners is to develop best practices. A number of research themes that seek to integrate natural history with eradication strategies and methodologies would improve the ability to eradicate ants: increasing natural history and taxonomic knowledge, increasing the efficacy of active ingredients and baits, minimizing and mitigating non-target risks, developing better tools to declare eradication success, and developing alternative eradication methodologies. Invasive ant eradications are rapidly increasing in both size and frequency, and we envisage that eradicating invasive ants will increase in focus in coming decades given the increasing dispersal and subsequent impacts.

The international community is increasingly aware of the link between biodiversity and sustainable development and its direct impact on wealth, health and well-being. Biodiversity is the origin of all crops and domesticated livestock. It is also the source of vital ecosystem services and functions, including soil conservation, water cycling, pollination, pest and disease regulation, carbon sequestration and nitrogen fixation. Biodiversity and the ecosystem services it supports are thus key to nutritional diversity and to agricultural productivity and resilience. The Convention on Biological Diversity (CBD) Strategic Plan for Biodiversity 2011–2020 and its 20 Aichi Biodiversity Targets provide a framework for countries to develop national targets and policies for sustaining biodiversity for a healthy planet. To meet rising global food demands, agricultural systems need to produce greater quantities of more diverse and nutritious food in a sustainable way. This progress can and must be achieved without driving biodiversity loss. It must come through gains in the efficiency of resource use, through sustainable intensification and a landscape perspective in agricultural production. By contributing to the conservation and sustainable use of biodiversity, agriculture will be a key driver for eliminating poverty, improving human health and providing energy, food and clean water for all while maintaining natural ecosystems.

Fisheries and aquaculture remain important sources of food, nutrition, income and livelihoods for hundreds of millions of people around the world. World per capita fish supply reached a new record high of 20 kg in 2014, thanks to vigorous growth in aquaculture, which now provides half of all fish for human consumption, and to a slight improvement in the state of certain fish stocks due to improved fisheries management. Moreover, fish continues to be one of the most-traded food commodities worldwide with more than half of fish exports by value originating in developing countries. Recent reports by high-level experts, international organizations, industry and civil society representatives all highlight the tremendous potential of the oceans and inland waters now, and even more so in the future, to contribute significantly to food security and adequate nutrition for a global population expected to reach 9.7 billion by 2050.l

Three-quarters of the Earth's surface is covered by oceans and seas which are an engine for global economic growth and a key source of food security. The global ocean economic activity is estimated to be USD 3-5 trillion. Ninety percent of global trade moves by marine transport. Over 30 percent of global oil and gas produced is extracted offshore. Expanding knowledge of marine biodiversity has provided breakthroughs in sectors such as pharmaceuticals, food production and aquaculture. Over 3.1 billion of the world's population lives within 100 kilometers of the ocean or sea in about 150 coastal and island nations.
