Quantitative analysis of the collected data revealed that soil erosion in the humid tropics is dramatically concentrated in space (over landscape elements of bare soil) and time (e.g. during crop rotation). No land use is erosion-prone per se, but creation of bare soil elements in the landscape through particular land uses and other human ...

The planting of sugarcane crops has expanded in the last decade in the southeast of Brazil, mainly due to its use for biofuel production, such as ethanol. This expansion in the State of São Paulo has occupied land that was previously used for cattle production. The change in land use affects soil and water through changes in ground cover and disturbance associated with farming practices.

A systematic review highlighted that until 2008, the concept of ES related to soil quality received less attention when compared to biodiversity [ 18 ]. In the last 10 years, several authors have proposed and developed conceptual frameworks and classifications of soil ecosystem services (SES) ( figure 1) [ 3, 6, 7, 9 ].

Soil erosion is thereby a major environment threat for the sustainability and ... the quantitative impact of erosion on yields (Magrath and Arens [6]). Erosion ... The Climate in Sleman is humid tropical with a distinct dry season from Mai until October. The average annual rainfall rages between less than 1500 mm and

This paper reports the results of soil erosion research carried out at the Visayas State College of Agriculture (ViSCA) on the island of Leyte in the Philippines. Hydrologic and soil erosion data for very steep, uniform slope, soil erosion plots are presented for a 3-yr period. These plots were kept bare by frequent hand cultivation and weeding.

We analyzed soil erosion control in the humid tropics. • More than 3600 measurements of soil loss were compiled. • Whatever the land use, most soil losses come from landscape elements of bare soil. • Soil erosion control is provided whenever vegetation is developed enough. • Conservation practices can reduce soil loss by up to 99%.

Soil erosion in the humid tropics: A systematic quantitative review

erosion. The experience in the humid tropical environment (and elsewhere) suggests that, the best approach to soil management is the river basin approach. This is due to the fact that the various components of the river basin viz, geology, soil vegetation, relief, and climate are interrelated and they operate together as a whole (Abua & Abua ...

In sites where agriculture production is common, soil erosion and nutrient depletion are typical, and without appropriate measures to maintain soil fertility, the land often becomes unproductive [].To counter the negative effect of the soil and nutrient loss, farmers tend to invest in agricultural and sustainable land management (SLM) practices that have the potential of improving land ...

Soil erosion has been considered a threat for semi-arid lands due to the removal of solid materials by water and wind. Although water erosion is currently considered the most important process of soil degradation, a growing interest has been drawn to the impact of soil tillage. Although numerous studies on tillage erosion have been carried out on arable land using a moldboard plow, a chisel ...

Erosion and Mechanization R. FAUCK The spread of mechanization of agriculture in humid tropical Africa has been characterized by a rapid increase in soil erosion. This fact has brought many to recommend, if not the rejection of mechanization, great prudence in its systematic utilization.

To understand the overall soil erosion conditions in citrus orchards, the exceedance probability distributions of the annual runoff coefficient (RC S, %) and annual soil loss (SL a, t·ha −1 ·yr −1) with and without SWCMs were calculated, and they are shown in Fig. 4.There is an approximately 80% probability that soil losses in a citrus orchard without SWCMs will exceed the tolerable soil ...

2.1 Study area and soil sampling. The study was conducted in the Eastern Usambara Mountains of Tanzania close to the village Amani (5 ∘ 06 ′ 00 ′′ S, 38 ∘ 38 ′ 00 ′′ E). The climate is humid monsoonal with a mean annual precipitation of 1918 mm and a mean annual temperature of 20.6 ∘ C with low variability within the study area (Hamilton and Bensted-Smith, 1989).

The objective of this study was to quantify the contribution of agroforestry practices to soil-mediated ecosystem services, specifically, regulation of soil erosion, storage of soil organic carbon (SOC) and nitrogen (N), availability of soil N and phosphorus (P) to crops, and alleviation of soil acidity across the humid and sub-humid tropics.

Soils contain the greatest terrestrial carbon (C) pool on the planet. Since approximately 12 % of soil C is held in cultivated soils, management of these agricultural areas has a huge potential to affect global carbon cycling; acting sometimes as a sink but also as a source. Tillage is one of the most important agricultural practices for soil management and has been traditionally undertaken to ...

Soil erosion in the humid tropics: A systematic quantitative review Healthy soils provide a wide range of ecosystem services. But soil erosion (one component of land degradation) jeopardizes the sustainable delivery of these services worldwide, and particularly in the humid tropics where erosion potential is high due to heavy rainfall.

The population explosion in the humid tropics is placing increasingly heavy demands on available land and water resources and in many places has led to poor land management practices, in turn causing an array of problems, ranging from diminished agricultural productivity via surface erosion, to increased downstream flooding and sedimentation.

Quantitative analysis of the collected data revealed that soil erosion in the humid tropics is dramatically concentrated in space (over landscape elements of bare soil) and time (e.g. during crop rotation). No land use is erosion-prone per se, but creation of bare soil elements in the landscape through particular land uses and other human ...

An in-situ water-induced soil erosion study of two years duration was conducted at a low slope of about 10%, and also on steep slopes of about 50%, 60% and 70% at the experimental site located at a soil and water research area contiguous to the Department of Agricultural Engineering and Applied Mathematics of the Visayas State College of Agriculture (ViSCA).
