Conservation challenge at the agricultural frontier: deforestation, fire, and land use dynamics in Mato Grosso

Abstract

Achieving conservation objectives within the rapidly changing agricultural frontier in Mato Grosso State requires tradeoffs between production and preservation. We provide a description of deforestation, fire, and land use dynamics during [2000][2001][2002][2003][2004][2005] to consider a range of strategies for conservation planning. Long-term conservation of Cerrado, transition forest, and Amazon biomes in the state can benefit from direct consideration of landscape structure, duration of post-clearing land use, and the mosaic of land uses surrounding potential conservation corridors or reserve areas. Although the creation of new protected areas may not be feasible, since few large, uninterrupted forest areas exist within the state, some conservation objectives can be met through greater coordination of the legal reserve system among property owners. We present three examples of landscape-level prioritization based on existing Forest Code regulations stipulating 80% forest reserves on private property. Through a state-mediated system, property owners could augment existing reserve areas on their property through purchase of lands in: 1) buffers surrounding existing conservation units and indigenous reserves; 2) small watersheds with little or no deforestation; 3) forest patches with high connectivity within specified mosaics of different land uses. Any final approach for property-level coordination will depend on the specific conservation goals (e.g., river corridors, bird habitat, or plant biodiversity), but we provide a framework for developing and implementing a conservation plan at the agricultural frontier. Tradeoffs in both conservation value and productive use are required to achieve coordinated conservation at scale.Keywords: Brazilian Amazon; change detection; MODIS; protected areas; conservation strategy.Desafios para conservação nas áreas de fronteiras agrícolas: desflorestamento, fogo e dinâmica do uso da terra no Mato Grosso RESUMO Para atingir os objetivos de conservação em áreas de rápida mudança na fronteira agrícola do Estado do Mato Grosso é requerido um balanço entre produção e preservação. Nós apresentamos uma descrição de desflorestamento, fogo e dinâmica do uso da terra no período 2000 -2005 para definir estratégias para o planejamento de conservação. A conservação a longo prazo das áreas de Cerrado, floresta de transição e do bioma amazônico no Estado pode se beneficiar diretamente das informações sobre a estrutura da paisagem, a MORTON, D.C.; SHIMABUKURO, Y.

Amazon vegetation: how much don’t we know and how much does it matter?

“…Some of the more accessible areas have also been subjected to selective logging, and in 2006 there was a concerted, albeit unsuccessful, attempt by Mato Grosso's Vice-Governor to reduce its area by 27,500 ha, including much of its most fertile land. The park is of some considerable conservation significance, lying in a strategic position in the southern Amazon conservation corridor proposed by the WWF (Morton et al 2007). This has been identified as an important buffer to northwards spread of the agricultural frontier into the Amazon.…”

“…This is consistent As can be observed in Figure 5, SL, characteristic of Brazilian Cerrado vegetation, burned extensively with a BA of ~28,000 km 2 , followed by FC with ~14,000 km 2 , which also had the highest number of AF, then CL with ~8000 km 2 of BA. It is anticipated that the fires, commonly used for grassland management, hunting activities and 'slash and burn' agricultural practices in Brazil [52,73], spread into adjacent SL and FC, where they became difficult to control and widespread. However, the higher number AF in FC suggests relatively smaller and isolated fires that could not spread to more extensive areas due to constantly wet conditions in the Amazon rainforest.…”
