Many societies have rules rooted in legal tradition that require the sustainable and efficient use of natural resources. The obligation of stewardship is a feature of
westernised legal systems. In nations following the common law tradition, the doctrine of waste requires owners of land to use it sustainably. Elsewhere, customary law systems
demand strict rules governing the allocation and use of resources. There is, therefore, an existing legal culture into which our generation's obligations towards the world's
resources can be set.
Coral reefs are vital ecosystems, providing a source of income, food arid coastal protection for millions of people; arid recent studies have shown that coral reef goods and services provide an annual net benefit of US$30 billion to economies worldwide
The Convention on Biological Diversity (CBD) defines its "strategy for the integrated management of land, water and living resources that promotes conservation and sus-
tainable use in an equitable way" as the Ecosystem Approach to management. This use incorporates the concept of an area used by humans as well as one containing plants and animals in a recognisable configuration.

Bioenergy occupies a unique position at the nexus of energy, environment, climate change and rural development agendas. Consequently, bioenergy and biofuels in particular, have seen
record levels of support in the form of subsidies, mandates and investments as governments seek to maximize the perceived synergies between the various opportunities offered by bioenergy. Whilst it is true that well- planned bioenergy development can reduce greenhouse gas emissions from a range of sources, increase rural incomes, reduce waste, improve access
Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worlds ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable.
The Convention on Biological Diversity has been adopted by many countries, resulting in the development of national biodiversity strategies. This illustrates the international recognition of the importance of protecting ecosystems. However, ecosystems still face many threats, some of them growing and spreading so rapidly as to cause irreversible deterioration in many countries and areas.
The world is facing a biodiversity crisis. Nowhere is that more apparent than on oceanic islands where invasive species are a major threat for island biodiversity. Rats are one of the most detrimental of these and have been the target of numerous eradication programmes; a well-established conservation tool for island systems.
The impacts of house mice (Mus musculus), one of four invasive rodent species in New Zealand, are only clearly revealed on islands and fenced sanctuaries without rats and other invasive predators which suppress mouse populations, influence their behaviour, and confound their impacts. When the sole invasive mammal on islands, mice can reach high densities and influence ecosystems in similar ways to rats.
Following the incursion of rats (Rattus rattus) on Taukihepa (Big South Cape Island; 93.9 km²) off southern New Zealand in 1963, and the subsequent extirpation of several endemic species, the New Zealand Wildlife Service realised that, contrary to general belief at the time, introduced predators do not reach a natural balance with native species and that a safe breeding habitat for an increasing number of at risk species was urgently needed.
Rat eradication is a highly effective tool for conserving biodiversity, but one that requires considerable planning eff ort, a high level of precision during implementation and carries no guarantee of success. Overall, rates of success are generally high but lower for tropical islands where most biodiversity is at risk. We completed a qualitative comparative review on four successful and four unsuccessful tropical rat eradication projects to better understand the factors influencing the success of tropical rat eradications and shed light on how the risk of future failures can be minimised.
The Baja California Pacifc Islands, Mexico, are globally important breeding sites for 22 seabird species and subspecies. In the past, several populations were extirpated or reduced due to invasive mammals, human disturbance, and contaminants. Over the past two decades, we have removed invasive predators and, for the last decade, we have been implementing a Seabird Restoration Programme on eight groups of islands: Coronado, Todos Santos, San Martín, San Jerónimo, San Benito, Natividad, San Roque, and Asunción.
Considerable bene?ts can be achieved for indigenous biodiversity when invasive vertebrates are removed from islands. In New Zealand, two logistically challenging eradications were undertaken, one to remove cats (Felis catus) and the other Paci?c rats (Rattus exulans) from Te Hauturu-o-Toi/Little Barrier Island (Hauturu). Here we document the short- and long-term impacts of these interventions on the biodiversity of Hauturu. We also assess the extent to which predicted outcomes were re?ected in the measured responses for a wide range of species.
The evaluation of management effectiveness is generally achieved by the assessment of series of criteria (represented by carefully selected indicators) against agreed objectives or standards. The following definitions refer specifically to the context of protected area management effectiveness.
