Evaporation from cultivated and semi-wild Sudanian Savanna in west Africa

Marc Parlange, Natalie Claire Ceperley, Theophile Mande, Nicolaas Cornelis van de Giesen

Rain-fed farming is the primary livelihood of semi-arid west Africa. Changes in land cover have the potential to affect precipitation, the critical resource for production. Turbulent flux measurements from two eddy-covariance towers and additional observat ...

Soil aggregation and associated nutrient content along a distance-from-tree gradient in a low input cropping system. Comparing the effect for two tree species: Mangifera indica (mango, Anacardiaceae) vs. Faidherbia albida (faidherbia, Fabaceae)

Pauline Chrobot

Trees can play a major role in improving soil quality and thus have the potential to enhance sustainability of agroecosystems. Although this has been well established, knowledge on the effect of individual trees on aggregate stability and associated-nutrie ...

Observation of Sensible and Latent Heat Fluxes Over a Mixed Savanna – Agricultural Catchment in the Semi-Arid Sudanian Savanna, Burkina Faso

Andrea Rinaldo, Marc Parlange, Natalie Claire Ceperley, Theophile Mande, Nicolaas Cornelis van de Giesen, Scott W. Tyler

Evaporation and the surface energy balance over two land cover types in Sudanian savanna were investigated in terms of their seasonal and interannual variability using four years of eddy covariance measurement (2009-2013). The observations demonstrate the ...

Use of a Distributed Sensor Network to Parameterize a Model of Flows between the Soil, Vegetation, and Atmosphere in a Mixed Savanna-Agricultural Catchment in South Eastern Burkina Faso.

Natalie Claire Ceperley

The hydrologic processes underlying a natural savanna in a semi-arid environment is altered when savanna is converted to agriculture. Inﬁltration is often observed to decrease while rapid runoff increases to the detriment of crop productivity, downstream p ...

The mid-Holocene vegetation of the Mediterranean region and southern Europe, and comparison with the present day

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins

Aim To contribute to the intense debate surrounding the relative influence of climate and humans on Mediterranean-region land cover over the past 6000 years, we assess the Holocene biogeography and vegetation history of southern Europe by means of an exten ...

Water use by Sclerocarya birrea Agroforestry Trees in Sudanian Savanna: Application of Wireless Sensor Networks

Natalie Claire Ceperley

Small scale rain fed agriculture is the primary livelihood for a large part of the population of Burkina Faso. Regional climate change means that this population is becoming increasingly vulnerable. Additionally, as natural savanna is converted for agricul ...

Reuse of domestic wastewater treated in macrophyte ponds to irrigate tomato and eggplant in semi-arid West-Africa: benefits and risks

André Mermoud

The scarcity of freshwater resources is a critical problem in semi-arid zones and marginal quality water is increasingly being used in agriculture. This paper aimed at evaluating the physico-chemical and biological risks on irrigated soils and fruits of ma ...

Heat and drought 2003 in Europe: a climate synthesis

Martine Rebetez

Heat and drought were extreme in summer 2003 in Europe. Climatic data show that most extreme were maximum air temperatures in June and August; maps of these two months show a striking similarity in geographical range. Over wide regions, monthly mean temper ...
