Forests and the goods and services they provide are essential for human well-being (Seppälä, Buck, & Katila, 2009). Forests provide three types of ecosystem services that directly support human well-being: provisioning services such as food, fuelwood, medicine, etc.; regulating services such as water purification, climate regulation, erosion control, etc.; and cultural services, including recreation, spiritual, and religious values (Millennium Ecosystem Assessment, 2003). About 1.6 billion people live in predominantly forest ecosystems or in their vicinity. Forest communities include indigenous peoples (IPs) who have been living since time immemorial in forest areas and other local groups including the more recent settlers or immigrants. In the tropics, over 800 million people are living in forests and woodlands, which makes these areas a very important resource for the rural poor (Chomitz, Buys, De Luca, Thomas, & Wertz-Kanounnikoff, 2007). Based on ADB's (2009a) estimates, half of the world's poorest of the poor are IPs, and more than half live in Asia. Sixty million of these IPs are forest dependent.

The ecological decline of ancient Near Eastern civilizations and the violent and explosive characteristics of post‐Columbian colonial ecologies might well remain comfortably remote from us in our twentieth century world were it not for the disturbing parallels that such case histories seem to evoke as we consider our contemporary global circumstance. Just as in ancient times and in the age of colonial expansion, it is in the “remote environments,” usually quite distant from the centers of power, that the crucial indicators of environmental catastrophe first become apparent within the system as a whole. These regions are frequently characterized by weak economies and highly vulnerable ecosystems in our time, just as they were in the past. Accordingly, the environmental circumstances in these regions constitute for the modern world a kind of monitoring device that can provide early warnings of ecological instabilities in the global ecosystem.

This paper aims to demonstrate the optimization of an existing residential building in a tropical climate using indigenous materials as an alternative to conventional building envelopes to achieve thermal comfort and affordable housing.

This study mainly adopted a quantitative research methodology through a comprehensive simulation study on a selected prototype building. The energy plus simulation tool in DesignBuilder was used to predict the average monthly and annual thermal comfort of a typical residential building in the study area. Also, a cost analysis of the final optimization interventions was conducted to estimate the construction cost savings.

The comparative analysis of simulation results for the base-case and optimized models indicates potential advantages in replacing conventional building envelope materials with indigenous materials. The base-case simulation results showed that the annual operative temperature is more than the adaptive thermal comfort set points in tropical climates, by 8.26%. This often leads to interventions using mechanical cooling systems, thus triggering overconsumption of energy and increase in CO₂ emissions. The building envelope materials for floor, walls and roof were replaced with low U-values indigenous materials until considerable results in terms of thermal comfort and overall building construction cost were achieved. The final simulation results showed that using indigenous materials for the ground floor, external walls and roof could substantially reduce the annual operative temperature by 8%, thereby increasing the predicted three months of thermal comfort in the base-case to nine months annually. Likewise, there was a 32.31%, 35.78% and 41.81% reduction in the annual CO₂ emissions, cooling loads and construction costs, respectively.

The knowledge of indigenous materials as an alternative to conventional materials for sustainable buildings is not new. However, most of the available research is focused on achieving affordable housing. There is a dearth of research showing the extent that these indigenous materials can be used to improve indoor thermal comfort in developing countries with tropical climates such as Nigeria.

The purpose of this paper is to propose a measurable terrestrial ecosystem boundary to answer the question: what extent of landscapes, bioregions, continents, and the global Earth System must remain as connected and intact core ecological areas and agro-ecological buffers to sustain local and regional ecosystem services as well as the biosphere commons?

This observational study reviews planetary boundary, biosphere, climate, ecosystems, and ecological tipping point science. It presents a refinement to planetary boundary science to include a measurable terrestrial ecosystem boundary based on landscape ecology and percolation theory. The paper concludes with discussion of the urgency posed by ecosystem collapse.

A new planetary boundary threshold is proposed based on ecology's percolation theory: that across scales 60 percent of terrestrial ecosystems must remain, setting the boundary at 66 percent as a precaution, to maintain key biogeochemical processes that sustain the biosphere and for ecosystems to remain the context for human endeavors. Strict protection is proposed for 44 percent of global land, 22 percent as agro-ecological buffers, and 33 percent as zones of sustainable human use.

It is not possible to carry out controlled experiments on Earth's one biosphere, removing landscape connectivity to see long-term effects results upon ecological well-being.

Spatially explicit goals for the amount and connectivity of natural and agro-ecological ecosystems to maintain ecological connectivity across scales may help in planning land use, including protection and placement of ecological restoration activities.

This paper proposes the first measureable and spatially explicit terrestrial ecosystem loss threshold as part of planetary boundary science.

Provides evidence, from a study on interregional marketing of selected food products carried out in Ecuador, of four problem areas for organisations concerned with marketing policy in less developed countries. Presents the four problems as: the differences between the marketing characteristics of different products; the variability of marketing drains, the relationships between scales of production and consumption and the structure of marketing chains, and the relationships between different types of marketing reform

Over the last decades, there has been an increasing interest among scientists on the linkage between population health and climate and environmental factors, as well as health impacts of climate change and climate variability. Numerous studies have been done and substantial results achieved, but mostly in the developed countries, and not much quantitative evidence or assessment of the impacts at national and local levels has been provided for developing countries.

The argument presented in this paper is based on distinctive and exploitable differences which merit putting eco-tourists, eco-resorts and the coastal tropics into categories of their own. Such differences should inform planning and design process when working in this environment, which is both very sensitive and valuable. The paper aims to describe the main characteristics of the coastal tropics as a climate targeted by eco-tourism. Differences between eco-tourists and residents are presented through definition of comfort. Climatic and other factors influencing comfort limits are at the core of discussion, in which passive design is seen as the most appropriate response to challenges of the tropical coast setting. The design opportunities for the desirable climate modifications in eco-friendly resorts together with some passive design features are briefly presented. These architectural design solutions are set against theoretical principles specific to tropical coastal regions. The focus is on human responses to environmental factors, and on their implications. The paper concludes with a few recommendations aimed to deliver indoor conditions consistent with climatic preferences of itinerant environmentally conscious users of buildings in the coastal tropics. Such an approach is expected to minimize impacts the facility will make on the environment.

The purpose of this paper is to investigate forest fires and their relationship to prevention and mitigation strategies based on the empirical problems raised by this study. Public policy implementation (in this case, the policy of forest fire management) is influenced by the role played by government and by the participation of the public and stakeholders (in this case, companies), as well as the effects of good governance. Thus, from the empirical problems associated with theoretical problems and normative problems, this study raises the influence of the role of central and local government on the implementation of forest fire prevention policy in Indonesia, which is moderated by the good governance variable.

This study used a quantitative approach by adopting survey methodology. The study has aimed to assess both large and small population groups, by selecting and reviewing carefully chosen samples of the population to find the incidence, distribution and relative interrelation of the variables considered (Kerlinger and Lee, 2000). The survey was undertaken in areas of Indonesia that have a high level of vulnerability to forest fires. There are currently six provinces – Riau, Jambi, South Sumatra, West Kalimantan, East Kalimantan and South Kalimantan – that have the highest intensity of forest fires. The study population was taken from 105 villages in those six major provinces experiencing forest fires. Sample size precision was determined by using Slovin’s formula with a precision of 10 percent and, thus, a sample size of 52 was obtained.

The central government’s activities have no significant effect on regional forest fire prevention. However, the results found that there is a significant effect caused by the interaction between the central and local governments and their governance of forest fire prevention. Even though the direct effect is not significant, the interaction effect significantly influences the forest fire prevention governance variable, which is a pure moderator. This study found that the role of central government has no effect on forest fire prevention. If the role of the central government is high, it will not impact the effectiveness of forest fire prevention, which is reflected in the aspects of prevention and early warning, reward and punishment, the improvement and management of ecosystems by reviewing courts, law enforcement and national and regional synergy.

This is one of the few public administration science studies to have investigated the relationship between good governance and forest fire policy in Indonesia, particularly the combined roles played by central and local governments.

The purpose of this paper is to examine the impact of corruption on the size of the shadow economy in countries that differ with respect to income level or geographical location. The underlying idea is that the primary manifestation of corruption might be associated with country characteristics and that different types of corruption might have different consequences.

IV regressions and bootstrapping are applied to a cross‐section of countries to show that geographical location of a country impacts on the relationship between corruption and the shadow economy. An interaction term of the level of corruption and geography is used to capture the differences in the types and consequences of corruption between countries.

Corruption does not seem to affect the size of the shadow economy outside the tropics. Instead, the higher the tropical area fraction of a country, the more a certain level of corruption enlarges the unofficial economy. Moreover, corruption and the shadow economy seem to be substitutes in the tropics.

Different types of corruption may have different consequences.

Unlike most of the previous literature, the paper accounts for the fact that some corrupt practices tend to be commonplace in some parts of the world, while other countries may be plagued by other types of corruption. Therefore, the consequences of corruption might also differ.

The purpose of this paper is to analyse thermal comfort and the thermal environment in naturally ventilated classrooms. Specifically, the aims of the study were to identify the thermal environment and thermal comfort of respondents in naturally ventilated university classrooms and compare them with the ASHRAE and Indonesian National Standard (SNI); to check on whether the predicted mean vote (PMV) model is applicable or not for predicting the thermal comfort of occupants in naturally ventilated university classrooms; and to analyse the neutral temperature of occupants in the naturally ventilated university classrooms.

The study was carried out at the new campus of Faculty of Engineering, Hasanuddin University, Gowa campus. A number of field surveys, which measured thermal environments, namely, air temperature, mean radiant temperature (MRT), relative humidity, and air velocity, were carried out. The personal activity and clothing properties were also recorded. At the same time, respondents were asked to fill a questionnaire to obtain their thermal sensation votes (TSV) and thermal comfort votes (TCV), thermal preference, and thermal acceptance. A total of 118 respondents participated in the study. Before the survey was conducted, a brief explanation was provided to the participants to ensure that they understood the study objectives and also how to fill in the questionnaires.

The results indicated that the surveyed classrooms had higher thermal environments than those specified in the well-known ASHRAE standard and Indonesian National Standard (SNI). However, this condition did not make respondents feel uncomfortable because a large proportion of respondents voted within the comfort zone (+1, 0, and −1). The predictive mean vote using the PMV model was higher than the respondents’ votes either by TSV or by TCV. There was a huge difference between neutral temperature using operative temperature (T_o) and air temperature (T_a). This difference may have been because of the small value of MRT recorded in the measured classrooms.

The research shows that the use of the PMV model in predicting thermal comfort in the tropic region might be misleading. This is because PMV mostly overestimates the TSV and TCV of the respondents. People in the tropic region are more tolerant to a higher temperature. On the basis of this finding, there is a need to develop a new thermal comfort model for university classrooms that is particularly optimal for this tropical area.
