Identifying the impact of agricultural management on soil invertebrates is still a challenge to research in the area of soil ecology. The aim of this study was to evaluate the diversity, richness, abundance and uniformity of the pedofauna in areas of traditional agroforestry systems involving burning (with intensive use, and after six and nine years of fallow) and a less-impacted system (BUSH) in the semi-arid region of Brazil. To do this, pitfall traps were installed along five transects in each system, and pedofauna diversity was analysed over seven consecutive days in the dry and rainy seasons. The collected invertebrates were classified into taxonomic groups, and their diversity, richness, abundance and uniformity were studied. During the dry season, the agroforestry systems showed low pedofauna diversity and uniformity, but with a richness similar to that of the BUSH system, whereas the traditional systems with fallow periods of six and nine years presented high diversity and uniformity. During the rainy season, the agroforestry systems had similar pedofauna abundance and richness compared to the BUSH system. The traditional fallow systems showed an abundance, richness, diversity and uniformity similar to the results under the BUSH system. Compared to the other areas, the traditional systems showed the greatest abundance and a similar richness, but less diversity and uniformity. When water is available, agroforestry systems support a diversity and uniformity of pedofauna similar to the less-impacted system.

RESUMO: O estudo investiga os efeitos do crédito rural, salário e emprego da agropecuária sobre o PIB (Produto Interno Bruto) do setor em uma perspectiva regional no Brasil para o período 2013-2017. Estimativas obtidas a partir de um modelo de vetor autorregressivo com dados em painel indicaram efeitos positivos de choques nas variáveis mencionadas sobre o valor adicionado bruto da agropecuária no Matopiba. Efeitos positivos também foram confirmados em termos de resposta do salário da agropecuária a impulsos nas demais variáveis e em termos de resposta do nível de emprego a choques no crédito rural. Os resultados da análise de decomposição da variância permitiram concluir que a magnitude do impacto na explicação das variações do PIB da agropecuária é elevada para o nível de salário, porém bem menor para o crédito rural, constituindo dinâmicas macroeconômicas que poderiam ser exploradas na condução das estratégias de desenvolvimento para a região. ABSTRACT: In this study, we investigate the effects of agricultural credit, wages, and employment on the industry?s gross domestic product (GDP) from a regional perspective ? Brazil ?, for the period between 2013?2017. Our estimates were obtained using a panel-data vector autoregression model and showed positive effects of shocks to these variables on the gross value added of agriculture at Matopiba. Positive effects were also confirmed by impulse responses of agricultural wages to the remaining variables, and by responses of the employment level to shocks in agricultural credit. The results of variance decomposition analysis indicate that the magnitude of the impact to variations in agricultural GDP is high for wage level, but quite lower for agricultural credit. These macroeconomic dynamics may be explored to guide development strategies for the region.
