Abstract: The rotational slash-and-burn agricultural system, largely dependent on the duration of the fallow period to restore the productivity of the land, is still extensively practiced by small land holders in the Northeastern Pará State, Brazil. Clear signs of agronomic and ecological failure of this system have been represented by consistently decreasing crop yields, fallow period shortening, and structural and compositional depletion of the natural recovering vegetation (capoeira). The SHIFT-capoeira research project (ENV-25) has been developing and introducing fire-free alternative management practices such as (i) the enrichment of the capoeira vegetation to improve biomass production and nutrient recovery/fixation, (ii) use of a bush-chopper that allow the mulching (instead of burning) of the biomass, (iii) mulch management/fertilization for optimal weed control and crop absorption of stocked nutrients, and (iv) crop rotation/association/cultivation techniques that are, on the one hand, adapted to fire-free agricultural production, and on the other, more suited to fulfil the household as well as the commercial needs of the farmers. The focus of this study is the evaluation of the contribution of these management alternatives for the sustainability of the agricultural activity developed by the small land holders in Northeastern Pará, with special reference to the non- monetary gains in terms of ecological function restoration and natural resources conservation afforded by fire-free management practices. The final purpose of the research effort is to draw indications of public policies directed to improving the efficacy of the development programs dedicated to the small land-holders of the region.

Caseous lymphadenitis is an infectious sheep and goats disease caused by Corynebacterium pseudotuberculosis and characterized by abscesses in superficial and visceral lymph nodes. C. pseudotuberculosis strains isolated from these hosts have been shown to be very difficult to type by the existing methods. The aim of this study is evaluating the potential of the Enterobacterial Repetitive Intergenic Consensus (ERIC-PCR) as a tool for molecular typing of C. pseudotuberculosis strains isolated in sheep. One hundred and twenty seven isolates of C. pseudotuberculosis were isolated from lesions suspected to have had caseous lymphadenitis collected from sheep at the slaughterhouse. Animals were from 24 flocks in 13 municipalities of the Minas Gerais State, Brazil. Species identification of the isolates was performed by routine biochemical tests and mPCR. Fingerprint was performed by RAPD using ERIC-1R, ERIC-2 and ERIC-1R + ERIC-2 primers. Seventeen different genotypes were generated by ERIC 1-PCR, 21 genotypes by ERIC 2-PCR and 21 genotypes by ERIC 1 + 2-PCR. Hunter-Gaston Discrimination Index (HGDI) found for ERIC 1, ERIC 2, ERIC 1 + 2 PCR were 0.69, 0.87, and 0.84, respectively. For most herds evaluated observed at most three different genotypes among isolates from animals of these property, in all ERIC-PCR assays. However a few flocks observed between four and nine genotypes per flock. The W Kendall value found for correlation among the three techniques of ERIC-PCR was 0.91 (P < 5.01 × 10−6). The results show that ERIC-PCR has good discriminatory power and advantages over other DNA-based typing methods, making it a useful tool to discriminate C. pseudotuberculosis isolates.
