Rainfall erosivity in interrill areas: Insights about the choice of an erosive factor

CATENA, 2019
Defining a suitable erosive factor for interrill erosion has been a long-going discussion that was not resolved by experimental results.: Insights about the choice of an erosive factor. In this paper, by using computational fluid simulations of individual raindrop impacts, the relevance of four erosive factors was assessed for a range of soil ...

Predicting Rainfall Erosivity in Honduras [PDF]

Soil Science Society of America Journal, 1997
Abstract Iso‐erodent maps can be used in soil conservation planning to identify regions with high rainfall erosive potential. This study was conducted to determine the significance of elevation in predicting the rainfall erosivity index ( R ) in addition to the average ...

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.

Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

American Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Rainfall erosivity estimation based on rainfall data collected over a range of temporal resolutions [PDF]

Hydrology and Earth System Sciences, 2015
Rainfall erosivity is the power of rainfall to cause soil erosion by water. The rainfall erosivity index for a rainfall event (energy-intensity values – EI30) is calculated from the total kinetic energy and maximum 30 min intensity of individual events ...

Atypical Long Barrows in the Cöeby Neolithic Cemetery (Trédion, Morbihan, France)? The Contribution of Electrical Surveys

Archaeological Prospection, EarlyView.
ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.
