Amea\u00e7as – caatinga<\/h2>\n

A explora\u00e7\u00e3o feita de forma extrativista pela popula\u00e7\u00e3o local, desde a ocupa\u00e7\u00e3o do semi-\u00e1rido, tem levado a uma r\u00e1pida degrada\u00e7\u00e3o ambiental. Segundo estimativas, cerca de 70% da Caatinga j\u00e1 se encontram alterados pelo homem e, somente 0,28% de sua \u00e1rea se encontra protegida em unidades e parques de conserva\u00e7\u00e3o. Estes n\u00fameros conferem \u00e0 Caatinga a condi\u00e7\u00e3o de ecossistema menos preservado e um dos mais degradados.
\nNo estabelecimento das \u00c1reas Priorit\u00e1rias para a Conserva\u00e7\u00e3o da Caatinga, quatro subregi\u00f5es foram identificadas, baseadas no grau de amea\u00e7as provenientes da utiliza\u00e7\u00e3o dos recursos naturais e socioecon\u00f4micos: a) Margens do Rio S\u00e3o Francisco; b) \u00c1reas de aq\u00fc\u00edferos subterr\u00e2neos; c) \u00c1reas com atividade de minera\u00e7\u00e3o; e d) Zonas sujeitas a processos de desertifica\u00e7\u00e3o.
\nAs margens do Rio S\u00e3o Francisco foram exploradas intensamente pelo desmatamento e utiliza\u00e7\u00e3o da madeira para alimentar as caldeiras dos barcos a vapor, causando desbarrancamento e assoreamento do rio. Os aq\u00fc\u00edferos subterr\u00e2neos foram utilizados de forma n\u00e3o-sustent\u00e1vel pela capta\u00e7\u00e3o da \u00e1gua para consumo humano e irriga\u00e7\u00e3o, interferindo nos processos naturais de recarga. A minera\u00e7\u00e3o \u00e9 uma das atividades humanas que mais geram impactos no meio ambiente, e nesse bioma encontram-se \u00e1reas com explora\u00e7\u00e3o de carv\u00e3o vegetal e gipsita, ambas no Estado de Pernambuco. Tamb\u00e9m no Estado de Pernambuco h\u00e1 zonas sujeitas a processos de desertifica\u00e7\u00e3o, com a vegeta\u00e7\u00e3o sendo permanentemente explorada para a pecu\u00e1ria extensiva e para a agricultura. A presen\u00e7a do gado \u00e9 um fator negativo para o ambiente, pois o gado compacta o solo por pisoteio.\n<\/p><\/div>\n

Threats – caatinga<\/h2>\n

Extractive exploitation by the local population from the beginning of the occupation of the semi-arid region has lead to rapid environmental degradation. Around 70% of the Caatinga is estimated to have been altered by man, and only 0.28% of its area is protected by conservation units and parks. These numbers confer to the Caatinga the status of the least preserved ecosystem, and one of the most degraded.
\nIn order to establish \u00c1reas Priorit\u00e1rias para a Conserva\u00e7\u00e3o da Caatinga (Priority Areas for the Conservation of the Caatinga) four subregions were identified based on the threat level caused by natural resource use and socioeconomic factors: a) the banks of the S\u00e3o Francisco river; b) areas with underground aquifers; c) mining zones; and d) desertifying areas.
\nThe banks of the S\u00e3o Francisco river have been intensely exploited through deforestation and use of the wood to feed steamboat boilers, resulting in landslides and aggradation. The underground aquifers have been non-sustainably used to extract water for human consumption and irrigation, disrupting natural recharge processes. Mining is one of the human activities with the greatest impact over the environment. Within this biome, both coal and gypsum are exploited in the state of Pernambuco. The state of Pernambuco also has desertifying areas, where the vegetation is permanently exploited for extensive grazing and agriculture. The presence of cattle is negative for the environment because the cattle causes soil compaction through trampling.\n<\/p><\/div>\n
