1. Losses of soil, water, organic carbon and nutrients caused by water erosion in different crops and natural savannah in the northern Amazon
Resumo Atualmente no Brasil a principal forma de erosão é causada pelo impacto das gotas de chuva na superfície do solo, desencadeando o processo de erosão hídrica e causando sérios danos às áreas agrícolas. Este trabalho foi realizado com o objetivo de avaliar perdas de solo, água, nutrientes e carbono orgânico em diferentes culturas, solo descob

2. Relationship Among Crop Systems, Soil Cover, and Water Erosion on a Typic Hapludox
ABSTRACT Several soil conservation practices are used to reduce water erosion and ensure sustainable agriculture. An effective crop management practice is intercropping, in which two or more crops with different architectures and vegetative cycles are grown simultaneously in the same area. We hypothesized that intercropping of corn and jack-bean increases so

3. Spatial Distribution of Annual and Monthly Rainfall Erosivity in the Jaguarí River Basin
ABSTRACT The Jaguarí River Basin forms the main water supply sources for the São Paulo Metropolitan Region and other cities in the state. Since the kinetic energy of rainfall is the driving force of water erosion, the main cause of land and water degradation, we tested the hypothesis of correlation between the erosive potential of rainfall (erosivity) and

4. Water Erosion in Different Slope Lengths on Bare Soil
ABSTRACT Water erosion degrades the soil and contaminates the environment, and one influential factor on erosion is slope length. The aim of this study was to quantify losses of soil (SL) and water (WL) in a Humic Cambisol in a field experiment under natural rainfall conditions from July 4, 2014 to June 18, 2015 in individual events of 41 erosive rains in th

5. Analysis Process Degradation / Desertification in Basin Creek Warlock Based on DFC, Municipality of Jaguaribe - Cearà / AnÃlise do processo de degradaÃÃo/desertificaÃÃo na bacia do Riacho Feiticeiro, com base no DFC, municÃpio de Jaguaribe - CearÃ
This research discusses the problem of degradation / desertification in the in the Feiticeiro stream basin. With an area of 236 KmÂ, is located northwest from the city of Jaguaribe, Ceara, inserted in the Jaguaribe river basin, which has a total area of 75.669 km Â. This study was developed based in the methodology of physical conservationist diagnosis, wi

6. ESTUDO DA DEGRADAÇÃO/DESERTIFICAÇÃO NO NÚCLEO DE SÃO RAIMUNDO NONATO PIAUÍ. / STUDY OF DEGRADATION / DESERTIFICATION IN CORE OF SÃO RAIMUNDO NONATO PIAUÍ.
A desertificação constitui um grave problema nos ambientes em que ocorre, qual seja as Terras Secas (áridas, semiáridas e subúmidas secas). Esse tipo de degradação afeta cerca de 1/4 da superfície terrestre, com implicações de ordem ambiental, econômica, política, social e cultural. No Brasil as áreas suscetíveis a esse processo localizam-se na

7. Erosividade das chuvas no Estado do Mato Grosso
Considering the importance of agriculture on conservation planning and management of water resources combined with the agricultural character of the Mato Grosso State, it is fundamental important the development of research that can help farmers and technicians in planning the soil conservation use and management. In this way, the objective of this study was

8. O FENÔMENO EL NIÑO OSCILAÇÃO SUL E A EROSIVIDADE DAS CHUVAS EM SANTA MARIA, RS / THE EL NIÑO SOUTHERN OSCILATION AND THE RAINFALL EROSIVITY IN SANTA MARIA, RS
Um dos fenômenos de grande escala que mais afetam o tempo e o clima de diferentes locais na superfície terrestre e que tem sido bastante estudado nas últimas três décadas é o fenômeno El Niño Oscilação Sul (ENOS). O ENOS provoca alterações na circulação atmosférica que afetam os elementos meteorológicos, principalmente a precipitação pluvio

9. THE UNSUSTAINABILITY OF SOIL USE WITH TABACCO CROP ON STEEP SLOPES / A INSUSTENTABILIDADE DO USO DO SOLO COM FUMICULTURA EM TERRAS DECLIVOSAS
Areas susceptibility to water erosion and strong pressure of soil use, as in Southern Brazil, where there is cultivation of tobacco, are prone to degradation of the natural resources. The objective of this dissertation was to evaluate the unsustainability of the natural resources in a watershed under tobacco production, characterized by steep slopes, with in

10. EROSIVIDADE, COEFICIENTE DE CHUVA, PADRÕES E PERIODO DE RETORNO DAS CHUVAS DE QUARAI E RIO GRANDE, RS / EROSIVITY, RAINFALL COEFFICIENT, PATTERNS AND RAINFALL RETURN PERIOD OF QUARAI AND RIO GRANDE, RS
The rainfall specifics characteristics vary from one region to another. The knowledge of the rainfall potential to cause erosion is necessary to plan agricultural and civil engineering activities. For Quarai and Rio Grande (RS, Brazil), were determined the rainfall erosivity and its relationship with precipitation and rainfall coefficient, rainfall patterns
