“…Thus, in cases where the Theil index equals zero, there is a monopoly market, i.e., with the maximum concentration. Whereas, in the Theil index upper limit, the "ln(n)", companies have similar shares in export representativeness in the market, demonstrating a minimum market concentration (RESENDE;BOFF 2002, SANTOS JUNIOR et al 2021. Similar to what was suggested for the HHI, Resende (1994) proposed an adjusted entropy index in cases of intertemporal analyses.…”

“…This coefficient measures the degree of inequality in exports of forest products between nations, since a concentrated market implies high inequality between countries participating in economic transactions. The index ranges between 0 and 1, with G = 0 indicating zero inequality in the market and G = 1 meaning absolute inequality (COELHO JUNIOR et al 2022, SANTOS JUNIOR et al 2021.…”

The world’s economy has undergone several changes and crises that may have altered the dynamics and structure of the forestry market after 2008. Thus, the objective of this study was to measure the concentration of the international market of the main forest products between 2008 and 2018. We used the Concentration Ratio [CR(k)], Hirschman-Herfindahl Index (HHI), Theil Entropy Index (E) and Gini Coefficient (G) to evaluate the forest products concentration. Our results showed that American and Asian countries have risen and taken positions of major forest products exporters to European markets over the years. The main exported product was “Paper and cardboard”, followed by “Lumber”, “Pulp”, “Wooden panels”, “Wood for industrial purposes” and “Energy”. Brazil's global share stood out in the pulp and paper segments. The forest products market concentration was classified as low for CR4, moderately low for CR8, unconcentrated and highly competitive for HHI and Entropy indices. Furthermore, the market was classified with inequality from very strong to absolute using the Gini index indicating that exports come from a small number of nations.

“…According to the North East Plant Association [7], one of the species that makes the state so relevant is the cashew trees. The authors point out that the need for pruning for fruiting interferes Still, regarding the high specialization of Alagoas and Pernambuco, Santos Júnior [51] highlighted the two states with the largest number of thermoelectric plants installed in the Northeast region of Brazil. Currently, there are 20 plants in each state, together totaling 74.1% of the regional thermoelectric plants.…”

Potentialities and Impacts of Biomass Energy in the Brazilian Northeast Region

et al. 2023

In Northeast Brazil, the use of biomass for energy generation is settled on traditional productive arrangements, such as a sugarcane production system in the humid Atlantic coastal area and firewood extraction from native tropical dry forests in the west. In parallel, substantial amounts of other biomass sources, such as residues from agricultural or urban processes, are still little used or wholly wasted, fudging the opportunity to generate new value chains based on these biomass sources. We hypothesize that using these non-traditional biomass sources to produce biofuels would significantly increase the regional bioenergy supply. In this context, this article discusses the potential for the production and use of biofuels and bioenergy in Northeast Brazil and its effects on regional development, which may be useful for both private actors and policymakers in the energy sector. The use of biomass sources for energy in the region is significant, reaching approximately 8.8 million tons of oil equivalent (toe) per year, emphasizing the already consolidated production of sugarcane and its derivatives. The use of all biomass resources in the Northeast region could supply around 4% of the Brazilian national electrical energy demand, with an environmental footprint of 0.055 tCO2eq per toe, which would contribute to reducing emissions from the Brazilian energy matrix generation. Regarding the spatial distribution of biomass sources, sugarcane prevails on the coast, firewood and livestock manure in the dryland area towards the west, and municipal solid waste is distributed throughout the region within urban areas. Different from what we expected, the potential energy recovery from municipal waste and animal manure would increase by only 17% the current bioenergy supply. In the future, since the majority of the region presents a semi-arid climate with limited rainfall, to increase the use of biomass as an energy source, there is a need to increase the supply of biomass sources with high efficiency in water use and good yields in drylands. For this, the cultivation and use of cacti and agave, for example, could contribute to making biorefineries viable in the region. Above all, public policies for harnessing bioenergy in NE Brazil must seek opportunities associated with the carbon/decarbonization economy, with studies being needed to assess the technical, economic, social, and environmental viability of future productive arrangements.
