“…The exemption of small farms to restore Legal Reserve deficits added 7 Mha, and the possibility to use natural vegetation in riparian buffer zones to fulfil deficits of Legal Reserves added 3 Mha, resulting in 36 Mha of additional land available for legal agricultural use compared with the prior Forest Act, most of it in the Amazon. Furthermore, Legal Reserve deficits in one farm can now be compensated by a surplus in other farms, and half of the required area for Legal Reserves can be planted with non-native tree species, including oil palm (Ab'Sáber 2010, de Sousa et al 2011, Tollefson 2011, Nazareno 2012, Sparovek et al 2012, Schwartzman et al 2014, Soares-Filho et al 2014.…”

Although mainly used for other purposes, and historically mainly established at the expense of tropical forests, oil palm can be the most land efficient feedstock for biodiesel. Large parts of Brazil are suitable for oil palm cultivation and a series of policy initiatives have recently been launched to promote oil palm production. These initiatives are however highly debated both in the parliament and in academia. Here we present results of a high resolution modelling study of opportunities and risks associated with oil palm production for biodiesel in Brazil, under different energy, policy, and infrastructure scenarios. Oil palm was found to be profitable on extensive areas, including areas under native vegetation where establishment would cause large land use change (LUC) emissions. However, some 40-60 Mha could support profitable biodiesel production corresponding to approximately 10% of the global diesel demand, without causing direct LUC emissions or impinging on protected areas. Pricing of LUC emissions could make oil palm production unprofitable on most lands where conversion would impact on native ecosystems and carbon stocks, if the carbon price is at the level $125/tC, or higher.

“…The reversal of Brazilian environmental legislation removes legal protection of vast natural areas [7], and can result in the extinction of species, qualitative and quantitative losses to agriculture, increased soil pollution, eutrophication of water bodies, imbalance of trophic networks, impacts on the pharmaceutical industry [11] and most of all the impoverishment of one of the greatest biodiversity areas of the planet.…”

“…Under its present government, however, Brazil has been steadily reversing its environmental legislation, ceasing to protect areas [7] and altering its environmental policies. Both the government and various society sectors are now divided into two camps: the so-called “ ruralista ” composed of large agribusiness producers allied with the majority of deputies and senators, who are opponents of the environmental agenda; and the “environmentalist” bench, composed of NGOs for environmental protection, the scientific academy, and a small number of politicians.…”

Legalizing Environmental Exploitation in Brazil: The Retreat of Public Policies for Biodiversity Protection

Brazil is the country with the most biodiversity in the world and also hosts the largest rainforest on the planet. Although Brazil was a pioneer of public policies for conservation of biodiversity and natural resources, it has recently jeopardized all biome conservation through questionable environmental policies. Over the past four years, the government has drastically altered its environmental legislation, removing vast areas from protection and encouraging overexploitation of natural resources,, which will result in loss of biodiversity, reduction of forest cover, and increased pollution of soil and water. The Brazilian political-social scene and its relationship with biodiversity conservation are discussed as well.

“…The new Brazilian Forest Code (implemented in 2012) reduced the protection of riparian vegetation, intentionally ignoring available scientific information (Ab'Sáber ; Metzger ), and increased the proximity between water bodies with croplands and pasture areas. These condition favours the processes of percolation and surface runoff that can increase the levels of phosphorus and nitrogen in water, the influx of contaminated effluents (e.g.…”

Agropastoral activities increase fluctuating asymmetry in tadpoles of two neotropical anuran species

Agriculture and pasture activities are the main drivers for habitat reduction, directly affecting amphibian assemblages. In the Cerrado, the progress of agricultural and pasture areas negatively affects aquatic environments and their organisms, once the suppression of marginal vegetation reduces the natural protection against allochtone stressors. One possible way to measure the stress level is the Fluctuating Asymmetry (FA), which is calculated based on the deviations in the development of bilateral morphological traits of the organism. Herein, we evaluated whether environments with a higher degree of agropastoral influence and reduced marginal vegetation can increase FA levels in tadpoles of two common and widely distributed anuran species in the Cerrado (Physalaemus cuvieri and Scinax fuscomarginatus). We sampled and classified water bodies according to the percentage of agropastoral land use and marginal vegetation, and measured four morphological traits of tadpoles to evaluate the degree of FA. We found that in environments with intensive agropastoral land use, tadpoles of P. cuvieri and S. fuscomarginatus had higher FA in nostril-snout distance (NSD). In environments with reduced marginal vegetation, tadpoles of S. fuscomarginatus had higher FA in eye width (EW), but no effect was detected for tadpoles of P. cuvieri. These morphological traits (i.e. nostrils and eyes) are associated to individual fitness of tadpoles. Thus, these developmental deviations can affect species fitness and population homeostasis over time, contributing to generate stochastic population dynamics and increasing the vulnerability of native species to local extinctions. The use of FA as a tool to measure environmental impact on species with potential to be used as bioindicators can contribute to generate and test hypothesis when integrated with long-term studies.
