“…This is supported by results of this study and other research on the status of regional habitats and their biodiversity [23] [27] [33] [34] [56]. Areas of Permanent Preservation (APP) and Legal Reserves (RL) form one of the main mechanisms for the protection of biodiversity in Brazil [70]. Those present in the Miranda basin require intensive supervision so that the representativeness of the remaining vegetation of the Brazilian biomes also is guaranteed on private property.…”

Changes in land use associated with the suppression of native vegetation can greatly alter the landscape configuration, affecting biodiversity and environmental services availability. This study analyzes how changes in land use affect landscape patterns of vegetation remnant over a 10 year period. We quantified spatial landscape patterns throughout a hydrographic basin for the years 2002, 2008, 2010 and 2012, using nine landscape metrics. An indicator of integrity was used to details the transformation processes occurring in the basin that could be used to monitor the impact of landscape changes and its spatial patterning. Results showed that over this decade, extension of farming activities reduced the cover of native vegetation by 4.4%, with grassy-woody savanna, wooded savanna and forested savanna impacted especially strongly. Suppression of vegetation across this period reduced the size of fragments and their connectivity. The landscape fragmentation indicator indicated that the fragmentation pattern varied spatially, with the upland areas along river headwaters, being most fragmented. Areas of floodplains vegetation, belonged to the Pantanal Wetland, although in better integrity states, are the most threatened by current pressures of land use change. An intense recovery program for headwaters and aquifer recharge areas, as well as riparian forests, is recommended to avoid the future depletion of water production. Besides, we also recommend the maintenance and recovering of the connectivity of the current remaining patches of natural vegetation corridors and elaboration of specific laws that incoporate the consolidated scientific knowladge about wetland ecosystem functioning, like the Pantanal.

“…This is all the more so because, in general, the precarious nature of the environmental bodies' institutional structure is a serious problem when it comes to managing native vegetation, and managing and inspecting rural properties in the country. This makes it more difficult to effectively comply with the law so these areas can perform their functions satisfactorily (BACHA, 2005;BERNARDO, 2010;MARQUES;VIANA et al, 2002). The environmental bodies still have little experience and knowledge of the possibility of applying and using AFS in legal reserves (RAMOS FILHO, 2007).…”

Sistemas agroflorestais como alternativa para as reservas legais

De acordo com a legislação ambiental brasileira, os Sistemas Agroflorestais (SAF) constituem uma alternativa para recomposição e uso das Reservas Legais (RL). Todavia, uma vez que SAF compreendem práticas muito heterogêneas, é pertinente discutir se, e quais Sistemas são adequados para cumprir as funções dessas áreas protegidas. O presente artigo visa apresentar elementos e considerações pertinentes a essas questões, com base em ampla revisão bibliográfica. A bibliografia aponta que o valor e potencial dos SAF para a conservação são limitados e controversos; a sustentabilidade e os benefícios proporcionados por esses Sistemas dependem de sua tipologia (estrutura e diversidade), da paisagem do entorno e da condução do manejo. Portanto, é imprescindível estabelecer critérios e limites para o uso dos SAF na restauração e exploração das RL, que considerem o grau de conservação e a extensão das RL e baseiem-se em estudos sobre a viabilidade ecológica e/ou ambiental desses Sistemas a longo prazo.

“…Among these legal obligations, the Forest Code demands the maintenance of Permanent Protection Areas (i.e. APPs) and a Legal Reserve, which represent "obligatory modalities of protected natural areas" (BRASIL, 2012a;SILVA;RANIERI, 2014, p. 116;MARQUES;RANIERI, 2012). Despite the importance of these instruments for the protection and restoration of essential ecological processes, various scientific studies observe a large quantity of Legal Reserve deficits on private properties (SOARES-FILHO et al, 2014a;SPAROVEK et al, 2012;STICKLER et al, 2013).…”

Regularization of Legal Reserve Debts: Perceptions of Rural Producers in the State of Pará and Mato Grosso in Brazil

et al. 2017

The native vegetation on private land is considered a key component in the supply of ecosystem services, so the Forest Code establishes the Legal Reserve. While some studies have showed that non-compliance is common, so far no study has analyzed the willingness of producers to settle this liability. This study aimed to investigate in a exploratory ways the stated preferences and the motivating factors of producers in the settlement of liabilities and use of Legal Reserve surpluses. With this purpose this study has collected primary data through structured face-to-face interviews with 77 producers in 17 municipalities in the states of Pará and Mato Grosso. The results showed four available classes of producers in regulation (positive, inaccurate, inaccurate and negative) and suggest that age, income and the type of agricultural activity are important factors in the decision-making process of farmers in relation to environmental regularization of their legal reserves.
