“…odorata also presented relatively slower growth among the studied species (MAI = 0.67 cm at 16 years), however the species mean annual increment is in accordance with the values found to the Amazon Forest (Dünisch et al, 2003;Cunha & Finger, 2013;Braz et al, 2015). Despite showing a slow-growth, this species is a light-demanding tree species, which adapts to gap environments and is recommended for forest enrichment plantations after timber harvesting (Pinedo-Vasquez et al, 2001;Vieira et al, 2018). Again, the density and competition conditions may have harmed the growth of this species in the study area.…”

The large amount of degraded areas and productive potential of the legal reserves in Brazil make restoration an environmental demand and a commercial opportunity. We modelled the diameter growth as a function of age of eight tree species in restoration plantations in the Brazilian Amazon. From 14 years of annual forest inventory data, for each species, we tested variations of logistic function: simple logistic, logistic with covariant (plant area at the time of planting), logistic with random effect, logistic with random effect and covariant. Amongst the studied species, Schizolobium parahyba var. amazonicum, Tectona grandis and Simarouba amara showed the highest growth rates while Cordia alliodora, Cedrela odorata and three species of the genus Handroanthus showed slower growth. The gains from using the covariant in modeling were small for both fixed and mixed-effect models. Gains from the inclusion of the random effect were substantial. Mixed-effect models had the best performance in modeling the growth of the species. Our results provide basis for a critical view of the criteria and possibilities for degraded areas restoration and management practices in legal reserves of the Amazon. An economic analysis is required to ensure the viability of these areas’ sustainable exploitation.

“…Assessments of socioeconomic, demographic, and environmental changes are fundamental to support the implementation of public policies that take into account regional and local sustainable development in the Amazonian arc of deforestation, which comprises the area along the eastern, southern, and western edges of the forest (Barreto et al 2008, Fearnside 2008. In this context, several studies have explored the regional levels of poverty, inequality, and social vulnerability in the Brazilian Amazon (Pinedo-Vasquez et al 2001, Sears et al 2007, Mangabeira 2010, Guedes et al 2012, Garrett et al 2017, as well as the negative social effects of deforestation in the region (Moran 1993, Celentano et al 2012) and the interactions between forest loss and socioeconomic patterns in deforestation frontiers , Celentano et al 2012). In general, these studies reveal that deforestation occurs on many fronts within the Amazonian arc of deforestation, which present distinct socioeconomic and demographic characteristics in a heterogeneous territory.…”

We focus here on deforestation and human development dynamics among 211 small and medium-sized municipalities (in terms of population) in the Amazonian arc of deforestation, Brazil. First, we construct a typology of municipalities through principal component analysis and cluster analysis. Using this typology, we seek to identify changing deforestation frontiers in the study area based not only on forest loss levels, but also on sets of socioeconomic and demographic elements associated with human development. We find four well-defined macro-deforestation frontiers that exhibit distinct interactions between forest loss and human development levels. Our results show different levels of demographic and economic pressures in these frontiers while revealing some important trends such as the internalization of investments and demographic growth in the arc of deforestation. In addition, population growth and inmigration and out-migration patterns in the explored municipalities suggest a demographic complementarity among frontiers. Finally, we explore implications for public policies seeking to advance forest recovery and long-term conservation through sustainable development growth at the local and regional levels.

“…Research on the relationship of people to plant species at a landscape level associates changes in soil use and cover over time with economic phenomena, migration to urban centers, globalization, and demography [6,9-14]. These events, which are triggered by human action, can permit the recognition of historical use of some detailed landscape patches defined as landscape units or ecotopes [15,16].…”

BackgroundPeople influence their environments through the manipulation of landscapes and species. Human influence on the landscape may lead to the development of differentiated landscape units that originate from past use and may be related to the presence of certain species. This study investigated the presence of the palm Euterpe edulis and its current and past importance in landscape units established by a community of German descendants located in southern Brazil. The objectives of this study were to characterize the use of the species, to identify the importance of E.edulis for the German immigrant community, to identify past and current uses of E.edulis, to describe the historical use of the landscape, and lastly, to identify landscape units in which E.edulis is found.MethodsThe researched community is composed of people of German descent residing in southern Brazil. A variety of research tools were used to achieve the objectives of the research. Semi-structured interviews and free-listings were conducted in all family units. The interviews focused on groups of people in the community who had current or historical connection with the species. Group workshops and guided tours were conducted to identify different landscape units. The data were analyzed using descriptive statistics, use-value index, citation frequency, salience index, and informant perception analysis.ResultsOver the historical period studied, the community demonstrated changes with respect to economic activities. These changes are reflected in the transformation of the landscape. The species E.edulis was and still is very important for people in the community; its importance is reflected in its high use value, citation frequency and salience. The species is found within various landscape units in the community as well as in homegardens and in secondary forests.ConclusionsThe landscape heterogeneity of this community is influenced by changes in economic activities and by the relationship with the conservation unit. Landscape units resulting from this relationship may be identified. The species E.edulis is found within these landscape units and is integrated into the livelihood of the community.
