Settler Welfare on Tropical Forest Frontiers in Latin America

Because of urgent concerns to protect tropical forests in Latin America, social science research on them has been generally ‘forest-centred.’ This forest-centred approach considers the people who inhabit the frontier as agents of land use change and forest conversion focusing on how their actions affect forest cover. Welfare indicators for forest frontier populations (income, education, health, access to basic services) are addressed only incidentally in terms of how they influence land use. ‘People’ centred research, which asks questions from the perspective of human welfare such as, ‘Are frontier settlers better off than they were before?’ or ‘What kind of socio-economic impacts does frontier life have on the people who live there?” and “How can their lives be improved?,” has been less common. As a result, we know much about the impacts, especially adverse impacts, which settler activity on the frontier has on forest cover but little about the impacts settlement has on settlers, themselves. This paper attempts to shift discussion towards these kinds of questions and a more people centred approach by reviewing existing research that directly addresses the welfare of settlers in tropical forest frontiers in Latin America. We also review research that touches on settler welfare by considering the concept of ‘sustainability’ on the forest frontier and stakes out a comprise position between ‘forest’ and ‘people’ centred questions or concerns. Settler welfare is defined primarily in economic terms. Household income, wealth, and agricultural productivity are interpreted a proxies for welfare in most cases. We also consider welfare in terms of access to basic services (health and education) and living conditions. We particularly consider how settler welfare indicators may change over time on the frontier. Tropical forests, defined as tropical, moist, broadleaf forests, are the main ecological setting of interest. These forests are generally the largest unoccupied areas in many Latin American countries and are thus, also the main ‘agricultural frontier’ or areas of new settlement by small farmers.     

Optimal Forest Management in the Presence of Intraspecific Competition

The Escalator Boxcar Train method is used to solve the distributed optimal control problems of forest management numerically. It takes into account intraspecific competition for scarce resources such as light, space, and nutrients during reproduction, growth, and mortality. It provides an alternative to gradient projection methods and Markov processes. It is implemented with standard software. The application is on the optimal forest management regime in the presence of intraspecific competition.     

Forest fires,air pollution,and mortality in Southeast Asia

I assess the population health effects in Malaysia of air pollution from a widespread series of fires that occurred in Indonesia between April and November of 1997. I describe how the fires occurred and why the associated air pollution was so widespread and long lasting. The main objective is to uncover any mortality effects and to assess how large and important they were. I also investigate whether the mortality effects were persistent or whether they represented a short-term, mortality-harvesting effect. The results show that the smoke haze from the fires had a deleterious effect on the health of the population in Malaysia.     

Mixed-Mode Oscillations Due to a Singular Hopf Bifurcation in a Forest Pest Model

In a forest pest model, young trees are distinguished from old trees. The pest feeds on old trees. The pest grows on a fast scale, the young trees on an intermediate scale, and the old trees on a slow scale. A combination of a singular Hopf bifurcation and a “weak return” mechanism, characterized by a small change in one of the variables, determines the features of the mixed-mode oscillations. Period-doubling and saddle-node bifurcations lead to closed families (called isolas) of periodic solutions in a bifurcation corresponding to a singular Hopf bifurcation.     

Challenging Neo‐Malthusian Deforestation Analyses in West Africa's Dynamic Forest Landscapes

Many influential analyses of West Africa take it for granted that ‘original’ forest cover has progressively been converted and savannized during the twentieth century by growing populations. By testing these assumptions against historical evidence, exemplified for Ghana and Ivory Coast, this article shows that these neo‐Malthusian deforestation narratives badly misrepresent people–forest relationships. They obscure important nonlinear dynamics, as well as widespread anthropogenic forest expansion and landscape enrichment. These processes are better captured, in broad terms, by a neo‐Boserupian perspective on population–forest dynamics. However, comprehending variations in locale‐specific trajectories of change requires fuller appreciation of social differences in environmental and resource values, of how diverse institutions shape resource access and control, and of ecological variability and path dependency in how landscapes respond to use. The second half of the article présents and illustrates such a “landscape structuretion” perspective through case studies from the forest–savanna transition zones of Ghana and Guinea.     

Multi-scale Analysis of Collaborative National Forest Planning Contexts in the Rural US Mountain West

This research analyzes regional and sub-regional contexts of the United States Mountain West where community-based forms of national forest planning are emerging to ameliorate conflict related to New West rural transformations characterized by high population growth and increasing service and amenity-based economies. A county-level typology is developed using cluster techniques applied to demographic, economic, and environmental indicators and a novel measure of spatial accessibility to forest lands. Results identify three types of contexts with differential characterestics relevant to community-based forest planning. A local scale analysis compares characteristics for counties surrounding a national forest with an ongoing community-based collaboration and its participant characteristics. Results show some key differences between participants and their ambient contexts as well as local-scale contextual heterogeneity. A framework for incorporating multi-scale data and analyses to address current research needs for the emergent topic of community-based collaboration is presented.Please address correspondence to Thomas W.

Income Dependency on Non-timber Forest Products: An Empirical Evidence of the Indigenous People in Peninsular Malaysia

The indigenous people have been identified to be among the poorest and the most socioeconomically and culturally marginalized people all over the world. The main purpose of the paper is to explore the socioeconomic and demographic factors of indigenous people in Peninsular Malaysia in context of poverty and the role of income dependency of non-timber forest products (NTFP). The data were collected in 2014 and 2015 through primary and secondary sources. Partial least squares (PLS) method was used to analysis the data. PLS is a modeling technique that features multiple regression and principal component analysis. The study shows that still a large number of indigenous households is involved in the NTFP activities. But the communities are moving away from NTFP based income to cash-crop based income because of poor sustainable forest management and lack of forest property rights. However, NTFP have a significant role in the household income and contribute 24% of the average income. Moreover, the analysis shows that location is significant to the poverty. There should be a suitable sustainable forest management system which can teach these indigenous communities about proper way of NTFP gathering and given proper rights to forest land. Furthermore, education is not significant to indigenous people and there is a high rate of school dropout among them. The government should introduce a different education system for indigenous communities which will emphasize the importance of education to them.

Effects of Central Decisions on Local Livelihoods in Indonesia: Potential Synergies Between the Programs of Transmigration and Industrial Forest Conversion

In addition to well-documented negative effects (e.g., environmental degradation and ethnic conflict) Indonesia's central government programs of transmigration and industrial forest management subvert indigenous rights (even if unintentionally) through appropriation of forested land and migrant subsidies. Although central control can be an effective strategy for resource management, Indonesia's programs have undercut their own objectives and may interact synergistically to increase population pressure, reduce available land, and intensify land use conflicts on the outer islands. Empirical data are needed to evaluate the interactions between transmigration and forest conversion and to design appropriate management strategies that incorporate local as well as central controls.     

Spatial and temporal residential density patterns from 1940 to 2000 in and around the Northern Forest of the Northeastern United States

Over the past 60 years, housing growth has outpaced population growth in the United States. Conservationists are concerned about the far-reaching environmental impacts of housing development, particularly in rural areas. We use clustering analysis to examine the pattern and distribution of housing development since 1940 in and around the Northern Forest, a heavily forested region with high amenity and recreation use in the Northeastern United States. We find that both proximity to urban areas and an abundance of natural amenities are associated with housing growth at the neighborhood level in this region. In the 1970s, counterurbanization led to higher rates of growth across rural areas. The Northern Forest now has extensive interface between forest vegetation and residential development, which has the potential to profoundly alter the ecological and social benefits of these forests.     

Differentials in divorce in maryland

The basic data needed for measurement of the risks of termination of the legal relationship of marriage by characteristics of the marital partners are not available at this time for the United States because the national divorce registration area includes less than half the States. Special studies based on selected census data or the records of marriages and divorces occurring in one State or community have provided much of the valuable but limited information at hand. Statistics for individual States are subject to substantial bias as a consequence of inter-State migration between time of marriage and time of divorce, but they must serve as a basic data source until national reporting has improved. A record linkage study was undertaken which tied marriages occurring in the State of Maryland in 1959 with divorces occurring in the State in the years 1959–66. Relative, not actual, divorce risks by race, age at marriage, and previous marital status were calculated for couples with at least one partner an in-State resident at the time of marriage. The dissolution rate was higher for whites than for nonwhites. Marriages contracted by persons at very youthful ages and by persons who had been married previously were found subject to greater than average risks of dissolution through divorce.

Increases in childlessness in New Zealand

New Zealand’s fertility fell below the theoretical replacement level (2.1 births per woman) for the first time in recorded history in 1978. It has hovered at or below replacement level ever since. The result, an impression of relative stability, belies changes taking place. Data from the 1981, 1996 and 2006 censuses show a pattern of delayed childbearing and increased childlessness. In a little over 30 years, childlessness has shifted from being almost entirely a consequence of a couple’s infecundity to being as frequently a result of a woman’s life choices. The steady rises in childlessness recorded by successive cohorts suggest that childlessness is already having a significant effect on New Zealand fertility. Patterns in characteristics of those women choosing not to start families, as well as subtle differences in these patterns between New Zealand and other developed nations, suggest that there is a significant potential for childlessness to cause a more dramatic shift in New Zealand’s total fertility rate. This analysis examines growth in childlessness in relation to marital status, country of birth, ethnicity, regional and urban differentials, religion, and educational attainment of women who were childless at the 1981, 1996 and 2006 censuses.

Shifts in Reproductive Patterns in China

The People's Republic of China, during the second half of the twentieth century, has been repeatedly affected by social and political upheavals associated with government policies. These have produced strong but unexpected impacts on Chinese demographic patterns. Many of these policies are of the sorts that alter reproductive costs and benefits. This study examines patterns in Hebei, Shaanxi, and Shanghai, three provinces with differing ecological, geographic, and economic characteristics. Government policies affected the three populations differentially; this was evident at both aggregate and individual levels. The Great Leap Forward and subsequent famine created higher birth deficits and mortality among the largely rural populations of Hebei and Shaanxi than the more urban Shanghai. In contrast, the Cultural Revolution and family planning resulted in lower fertility levels for women in Shanghai. The population history of China during the second half of last century thus reflects strong state interventions in the lives of its citizens. Government policies, along with regional variations in geographic, social, and economic conditions, strongly influence individual access to resources in China. Variations in timing and intensity of women's reproductive patterns reflect differential access to resources and subsequent trade-offs.     

Materialism in Pedagogy Students in Chile

Many studies have used Richins and Dawson’s (J Consum Res 19: 303–316, 1992) Material Values Scale (MVS), applying it to different types of populations that exhibit a particular psychometric behavior, and showing little stability in their factorial structure. In the present study, 1,070 pedagogy students from the northern, central and southern regions of Chile answered the MVS. This sample was randomly divided in two. Using the first sub-sample (N = 539), an exploratory factorial analysis was carried out, from which a structure of nine items was grouped into two factors called “Social Success” and “Personal Happiness”, which presented adequate reliability. Later, with the second sub-sample (N = 531), the factorial structure indicated above was put to the test through a confirmatory factorial analysis. The data from the model show that the scale contains 8 items in total, grouped into two dimensions. The factorial loads are significant at the level of 1 %, which indicates that the 2-factor structure can be confirmed. Finally—using the proposed structure—the presence of the students’ material values was evaluated.
