“…The first forestry companies arrived in southern Bahia at the beginning of 1980, encouraged by soil and climate conditions, land availability and price, availability of labor, and feasibility of forest products distribution (Almeida et al, 2008). Specifically, in the regions selected, land use change occurred primarily from native forest being replaced by grassland cultivation.…”

Eucalyptus forests in southern Bahia (BA) are planted in soils with a sandy surface layer and humid tropical climate, conditions that lead to soil carbon (C) decomposition. Recent studies have shown that nitrogen (N) may be important for soil C stabilization. The aim of this study was to evaluate the contribution of Eucalyptus harvest residues and nitrogen fertilization to C stabilization in Ultisols of southern BA. The experiment was conducted in Eucalyptus clonal plantations cultivated in two regions of Eunápolis, BA, Brazil, with different clay content: southern region (140 g kg -1 of clay) and western region (310 g kg -1 of clay). Five treatments were evaluated: one control (CTR), without Eucalyptus harvest residues and N fertilization, and four treatments with harvest residues combined with four rates of N fertilization: 0, 25, 50, and 100 kg ha N) of particulate organic matter (POM) and mineral-associated organic matter (MAOM) were determined. In the southern region after 36 months, the C-MAOM stocks in the 0.00-0.10 m layer of the CTR decreased by 33 %. The addition of harvest residue followed by 100 kg ha -1 N increased C-POM and N-POM stocks (0.00-0.10 m) compared to the CTR, and the final N-POM stocks and residue-C recovery in the surface soil layer were positively correlated with the increase in N fertilization rates. In the western region, residue maintenance resulted in increased C-MAOM stocks (0.00-0.10 m) compared to the CTR, but an increase in N availability reduced this increment. The increase in N fertilization rates did not alter C stocks, but reduced N stocks of POM and MAOM in the upper soil layer. At the end of the experiment, N fertilizer recovery (0.00-0.60 m) was similar among the regions evaluated. In soil with lower clay content, higher N availability led to higher C and N stocks in the particulate fraction. In soils with high clay content, physical and chemical protections are more important than N fertilization for soil C stabilization, and just maintaining harvest residues may suffice to increase C and N in the more stable SOM fraction.

“…The expansion of the agricultural frontier, pastures for livestock, and eucalyptus monoculture plantations for cellulose production further increased deforestation rates in the region. To conserve some of the remaining forest in the area, the Mata Atlântica Biosphere Reserve (MABR) was declared in 1993 (Diegues 1995, de Almeida et al 2008. Although well-conserved http://www.ecologyandsociety.org/vol20/iss3/art33/ natural vegetation is only present in 8% of the MABR (GalindoLeal and Camara 2003), it is considered a biodiversity hotspot, mostly for plant species, and is one of the most diverse biomes and important endemism centers of the world (Diegues 1995, Ribeiro et al 2009, Lino et al 2011.…”

ABSTRACT. Indigenous and rural communities have developed strategies aimed at supporting their livelihoods and protecting biodiversity. Motivational factors underlying these local conservation strategies, however, are still a largely neglected topic. We aimed to enrich the conceptualization of community-based conservation by exploring trigger events and motivations that induce local people to be engaged in practical institutional arrangements for successful natural resource management and biodiversity conservation. By examining the history and development of three community conservation initiatives in Brazil, Mexico, and Bolivia, we have illustrated and discussed two main ways of understanding community-based conservation from the interaction between extrinsic and intrinsic motivations. First, incentive-based conservation policies can stimulate people's economic interests and mobilize individual and collective behavior toward the formalization of conservation-oriented actions. Second, environmental justice concerns, such as international and national movements for the recognition of indigenous peoples' rights, can support local people's sense of autonomy and result in increased control over their territory and resources, as well as a renewed conservation commitment. The results are useful from a policy perspective because they provide insight into the governance of conservation development by bridging the gap between communities' culturally based motivations for conservation, which are still embedded in customary institutions, and broader political and socioeconomic contexts.

“…Critical data analysis combined with satellite imagery revealed 256,000 ha of land had been converted from cattle ranching to plantations during the 10-year period (IMA/LIMA, 2009), this was not surprising given the low economic return, area-wise, from cattle (125-160 USD per hectare and year; IMA/LIMA, 2009). Public statistic reveal a steady decline of rural population since the 1970s heydays of native forest logging, resulting in a 50% decline in rural population between 1980 and 1990 (Almeida et al, 2008), this out migration continues today at a lower rate. Meanwhile, urban areas grew rapidly, with immigrants from other states and regions outnumbering rural people from the neighbouring areas.…”

a b s t r a c tThe large-scale pulp investment model, with its pressure on land, has created conflict and caused major disagreements and open hostility amongst the social movement and NGO networks, state actors, and the pulp and paper companies in Brazil. In this article, Ethical Analysis was applied in the assessment of the dynamics and possibilities of conflict resolution related to the expansion of pulpwood plantations in Brazil's Bahia State, particularly near Veracel Celulose. Ethical Analysis as a tool identifies the complex dynamics of contention through identifying bridges and rifts in the social, ecological and economic viewpoints of the main actors. The analysis was based on field research, interviews, and a review of existing literature. The results indicated that the conflict is marked by politics of power, and as long as this stage continues, the politics of cooperation and conflict resolution would be hard to achieve. The key actors have diverging interests, values and principles, and different ways of presenting their viewpoints. The current investment context is economically and institutionally peripheral and socially weak. Without a radical rethinking and emphasis on ethical and structural reworking of the investment model, the conflict will likely continue to deepen, aggravating investment risk for large-scale business and industrial forestry.
