Article
Full-text available
Due to complex interactions, changes in any one area of food systems are likely to impact—and possibly depend on—changes in other areas. Here we present the first annual monitoring update of the indicator framework proposed by the Food Systems Countdown Initiative, with new qualitative analysis elucidating interactions across indicators. Since 2000...
Article
Full-text available
Introduction Efforts are underway to transform food systems in light of their contributions to global challenges like climate change. However, food systems are highly complex, involve noteworthy place-based challenges, and there is often debate and disagreement among experts over appropriate technologies or interventions to prioritize. Tracking pro...

For many decades, food-based dietary guidelines (FBDGs) were only health-oriented. This changed post-2009 when gradually, an increasing number of countries began to include environmental sustainability considerations in their guidelines. International organisations such as the Food and Agriculture Organization (FAO) and the World Health Organizatio...
Article
Full-text available
A new food system indicator framework and monitoring architecture is presented to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) r...

Indonesia is embarking on an ambitious relocation of its capital city to Kalimantan, Borneo, bringing with it major urban and road infrastructure. Yet, despite being one of the world's most biologically diverse regions, the potential implications of this development for wildlife have yet to be fully assessed. We explored the potential impacts of th...
Article
See corresponding article on page 1039. The past few years have been an important time for food systems. Numerous studies (1, 2) have pointed to the sweeping benefits of a global food system transformation, the first ever United Nations Food Systems Summit brought together a broad group to stakeholders to accelerate action on food systems, and glob...

Food systems that support healthy diets in sustainable, resilient, just, and equitable ways can engender progress in eradicating poverty and malnutrition; protecting human rights; and restoring natural resources. Food system activities have contributed to great gains for humanity but have also led to significant challenges, including hunger, poor d...
Article
Full-text available
Tropical forest ecosystems are the most species-rich in the world and face intense pressures from land conversion. If done well, selective logging can be an important way of supporting local economies while minimally impacting wildlife. However, most studies on how selective logging affects wildlife come from sites that have been logged some time a...
Article
Full-text available
Malnutrition in all forms, ranging from undernourishment to obesity and associated diet-related diseases, is one of the leading causes of death worldwide, while food systems often have major environmental impacts. Rapid global population growth and increases in demands for food and changes in dietary habits create challenges to provide universal ac...
Article
Full-text available
The food system is a major driver of climate change, changes in land use, depletion of freshwater resources, and pollution of aquatic and terrestrial ecosystems through excessive nitrogen and phosphorus inputs. Here we show that between 2010 and 2050, as a result of expected changes in population and income levels, the environmental effects of the...
Article
Full-text available
Camera traps set to monitor target species generate large amounts of bycatch data of non-target species, which are secondary to the study’s objectives. Bycatch data pooled from multiple studies can answer additional questions that were not the objective of the primary studies. Variation in field and data management techniques creates logistical and...

The Sunda clouded leopard Neofelis diardi is a medium sized (15–25 kg) cat, found only on the Sundaic islands of Borneo and Sumatra. In recent years intensive camera-trapping surveys in Borneo have begun to shed light on the habitat associations and basic ecology of this elusive wild cat, but its distribution on an island-wide scale remains very po...
Article
Full-text available
The first comprehensive survey of gibbons (Hylobates spp.) across Indonesian Borneo was carried out over 3 years to (1) determine whether densities of gibbon species are correlated with vegetation characteristics, and if so, whether the same characteristics are correlated with density across all forest types; and (2) determine population densities...
Article
Accurate information on the density and abundance of animal populations is essential for understanding species' ecology and for conservation planning, but is difficult to obtain. The endangered orangutan (Pongo spp.) is an example; due to its elusive behavior and low densities, researchers have relied on methods that convert nest counts to oranguta...
Article
Responses of biodiversity to changes in both land cover and climate are recognized [ 1 ] but still poorly understood [ 2 ]. This poses significant challenges for spatial planning as species could shift, contract, expand, or maintain their range inside or outside protected areas [ 2–4 ]. We examine this problem in Borneo, a global biodiversity hotsp...
Article
Full-text available
There is a lack of information on how the Endangered Bornean orang-utan Pongo pygmaeus morio moves through its environment. Here we report on a camera-trapping study carried out over 2.5 years to investigate the orang-utan's terrestrial behaviour in Wehea Forest, East Kalimantan, Indonesia. We set 41 camera trap stations in an area of secondary for...

The orangutan is the world's largest arboreal mammal, and images of the red ape moving through the tropical forest canopy symbolise its typical arboreal behaviour. Records of terrestrial behaviour are scarce and often associated with habitat disturbance. We conducted a large-scale species-level analysis of ground-based camera-trapping data to evalu...
Article
Aside from anecdotal evidence, terrestriality in orangutans (Pongo spp.) has not been quantified or subject to careful study and important questions remain about the extent and contexts of terrestrial behavior. Understanding the factors that influence orangutan terrestriality also has significant implications for their conservation. Here we report...

Our group donned surgical masks to prevent the transmission of disease and quietly approached the orangutans. We wandered down a crumbling walkway, pushing back the encroaching jungle, and made our way to the back of the facility where 18 orangutans were locked in cages. We spent the next hour talking, holding hands and connecting with these amazin...
