1. Achados de fundoscopia de pacientes diabéticos e/ou hipertensos
ABSTRACT Soil compaction in agricultural areas has greatly increased in recent decades due to intensive farming practices, including short-cycle crops and machinery intensification. This study aimed to evaluate the impacts of management systems on the physical quality of a dystrophic Yellow Oxisol, in the Cerrado region of Brazil. Treatments consisted of fiv

3. Temporal evaluation of soil chemical attributes after slash-and-burn agriculture in the Western Brazilian Amazon
ABSTRACT. In Amazonia, the main causes of deforestation are systems based on slash-and-burn agriculture. The objective of this work was to evaluate temporal changes in the soil chemical attributes after the vegetation has been slashed and burned in an area of native forest in the Western Amazon. For this study, four hectares of forest in Cruzeiro do Sul, Sta

4. Land Use and Changes in Soil Morphology and Physical-Chemical Properties in Southern Amazon
ABSTRACT Many Amazonian farmers use the slash-and-burn method rather than fertilization for crop production. The aim of the present study was to evaluate changes in the morphological, physical, and chemical properties of naturally fertile Inceptisols after conversion from native forest to different uses in southern Amazonia, Brazil. Land covered by dense nat

5. High fire temperature changes soil aggregate stability in slash-and-burn agricultural systems
ABSTRACT Fire is a key controlling factor in ecosystem dynamics worldwide, especially, in tropical areas under slash-and-burn agricultural systems. Farmers use fire as a tool to clean the land, and benefit from nutrient enrichment from ash-soil heating. However, fire can cause some detrimental effects on soil systems, such as organic carbon depletion, increa

6. Aspectos etnoecológicos de la agricultura entre los Pumé
Abstract This article reports on agricultural management techniques among the Pumé from an ethnoecological perspective. The Pumé are an indigenous people that inhabit the Llanos ecoregion in Venezuela. Although some ethnographers consider them to be primarily a hunter-gatherer group, there are also reports going back to the colonial era indicating that the

7. Agriculture itinérante sur brûlis (AIB) et plantes cultivées sur le haut Maroni: étude comparée chez les Aluku et les Wayana en Guyane française
Abstract In the late 18th century, Aluku Maroons, descendants of rebel slaves from Dutch plantations and Wayana Indians, fleeing from Brazilian slave hunters met on the upper Maroni in French Guiana. They shared the river and several techniques of subsistence, including slash and burn agriculture, and cultived plants. However our study shows that ancestor wo

8. Phosphorus Forms in Ultisol Submitted to Burning and Trituration of Vegetation in Eastern Amazon
ABSTRACT The use of fire to prepare agricultural areas is a technique still used by small farmers in eastern Amazon. This type of management changes the dynamics of soil nutrients, especially phosphorus, which constitutes the most limiting nutrient for crop production in tropical soils. This study was carried out to evaluate changes in phosphorus forms in an

9. Cashew cultivation in Guinea-Bissau – risks and challenges of the success of a cash crop
In recent decades a boom in cashew (Anacardium occidentale)cultivation has taken place in Guinea-Bissau, leading to the replacement of traditional slash-and-burn agriculture by a cash crop. As a result, the country is currently one of the world’s largest producers of raw cashew nuts and the cashew sector has acquired enormous importance in Guinea-Bissau’

10. A tutela da diferença no direito socioambiental pós-moderno: um estudo de caso sobre a prática da agricultura de corte e queima pela Comunidade Quilombola de Ivaporunduva / Tutelage of \"different/diverse\" communities in post-modern socioenvironmental right: a case study on slash and burn agriculture practiced by the Quilombola Community of Ivaporunduva, SP, Brazil.
This research aims at developing a thorough analysis of the Right that arose with modernity. Based on the hypothesis that even though Post-Modern Right autodenominates itself the advocate of diversity, it is still tied to the legality model of judicial positivism. The Right is ongoing an important crises, and at the time that eliminates customary rules, elim

12. Memória social e ecologia histórica: a agricultura de coivara das populações quilombolas do vale do Ribeira e sua relação com a formação da mata atlântica local / Social memory and historical ecology:slash and burn agriculture in the formation of an Atlantic rainforest area inhabited by quilombola communities, Ribeira Valley, Brazil
The Atlantic Rainforest is one of the worlds most diverse and threatened biomes. The majority of its remnants are located at the Ribeira Valley (SP) where several of the States quilombola populations remain. The Valleys quilombos originated from a population of freed, abandoned or refugee slaves brought to the region in the beginning of the European coloniza
