The 2015 Human Development Report is the latest in the series of global Human Development Reports published by the United Nations Development Programme (UNDP) since 1990 as independent, analytically and empirically grounded discussions of major development issues, trends and policies.

Invasive alien species such as Spathodea campanulata (African tulip tree) threaten biodiversity in the Pacific islands as well as the economic, social, and cultural wellbeing of Pacific peoples. Despite the potential magnitude of these threats, our scientific understanding of the ecology and management of the African tulip tree is nascent. In this paper, we use data from novel surveys of households and communities to document the direct and direct impacts of African tulip tree in Fiji, focusing on those impacts which may be monetised. We use the same data to describe current management approaches and then describe a state-of-the-science, ‘‘integrated’’ management approach that employs different strategies for trees of different ages and sizes. These two approaches are then compared in a comprehensive cost–benefit analysis. We find strong arguments for pursuing the integrated management approach, which derives monetised benefits of $3.7 for each $1 spent. However, the less costly current approach is also strictly preferred to the baseline, ‘‘do nothing’’ approach, with monetised benefits of $2.7 for each $1 spent. Results of this analysis clearly show that managing African tulip tree is cost effective, even without explicitly considering biodiversity, culture, and other non-monetised benefits of control.

Taro (Colocasia esculenta (L.) Schott) plays a prominent role in the economies and cultures of Pacific Island countries such as Fiji. Unfortunately, taro is highly susceptible to invasion from taro beetles, which burrow into the corms and weaken the plants, rendering them unmarkable and prone to rot. Papuana uninodis Prell, an invasive alien species that is native to the Solomon Islands and Vanuatu, was first reported on Viti Levu (Fiji's largest island) in 1984. Since that time, taro production on Viti Levu has fallen substantially. In this paper, we employ data from surveys of households and communities to document the impacts of P. uninodis on Viti Levu. We then identify three management approaches-chemical controls, cultural controls, and switching from taro to another staple crop-and conduct a cost-benefit analysis of each. We find strong arguments for pursuing chemical control, which derives a net present value of monetised benefits of about FJ$139,500 per hectare over 50 yr, or >FJ$21 for each FJ$1 spent. Still, any of the three management options is more efficient than no management, even without any attempt to quantify the benefits to biodiversity or forest protection, underscoring the value of actively managing this invasive alien species.

Invasive species pose an enormous threat in the Pacific: not only do they strongly affect biodiversity, but they also potentially affect the economic, social and cultural wellbeing of Pacific peoples. Invasive species can potentially be managed and their impacts can potentially be avoided, eliminated, or reduced. However, neither the costs nor the numerous benefits of management are well understood in the Pacific. Thus, we undertook cost-benefit analyses (CBAs) of managing five species that are well established on Viti Levu, Fiji: spathodea campanulata (African tulip tree), herpestus javanicus (small Asian mongoose), papuana uninodis (taro beetle), pycnonotus cafer (red-vented bulbul), and merremia peltata (merremia vine). These CBAs are informed by extensive survey data that record the incidence, management, and impacts of five species in Fiji. Wed find that the most cost-effective management option varies by species, precluding a universal solution. Nevertheless, the benefits of management often exceed the costs of management by a wide margin, arguing for a more concerted effort to control the spread of invasive species in the Pacific.

Reducing the risk of climate change requires large and rapid reductions in greenhouse gas emissions, most of which are caused by the burning of fossil energy sources (1). The debate around emission reductions has been dominated by concern for economic growth, and its reliance on cheap and plentiful energy. Instead, I believe energy’s role in achieving human development should be our core priority.

The concept of ‘climate finance’ has gained considerable currency following commitments from developed countries to provide new and additional funding for action on climate change. There have been a series of studies estimating the size of the financing need and assessments of how the international financing architecture can meet those needs. Sources of ‘climate finance’ comprise not only finance that governments spend, but also private finance for private actions on climate change. These studies have served a useful purpose of putting the mobilization and effective use of increased international resources for action on climate change firmly on the agenda.

The Pacific Islands Greenhouse Gas Abatement through Renewable Energy Project (PIGGAREP) is a Global Environment Facility (GEF) US$5.25 million project in eleven Pacific Island Countries (PICs). Implementation of the project started on 1 January 2008. PIGGAREP’s planned five year duration has been extended to six and a half years, with a scheduled end date now of December 2013.

In 1989, the Asian Development Bank provided technical assistance to the then Department of Agriculture and the Survey Department through a NZ Consulting Firm - ANZDEC under an ADB Land Resource Planning Survey Project. The Project provided training on mapping and GIS capability for the survey staff who were involved in the mapping work. Electronic GIS data and equipment were handed over to the Department of Agriculture at the end of the project which were later on damaged by Cyclone Ofa in 1990. A decade later, the Integrated Climate Change Risks in Agriculture and Health Sectors (ICCRAHSS) Project funded by the GEF through UNDP contracted the services of a consultant to provide: -improved GIS maps for soil, crops and rainfall distribution under different climatic projections; -review existing GIS systems and possible areas for collaboration; -consider a program to support capacity building on the use of the system and; -some applications that addresses options for climate change adaptation for the agriculture sector. Based on this report, a GIS system for the Ministry of Agriculture was procured to address the need for such a system to be in place with the expectation that the system will be properly utilized and maintained by relevant people.
