Agricultural Expansion-Induced Infiltration Rate Change in a West African Tropical Catchment

Modelling of Land-use Changes in a West African Catchment

Land-cover and land-use changes are an important part of global change but determine as well livelihoods at local and regional level. The knowledge of change trajectories and possible future conditions is important for a sustainable development strategy. Further on, reliable scenarios with spatial explicit simulations are needed as planning tools for decision makers. This paper describes an exa...

Hydrologic effects of the expansion of rubber (Hevea brasiliensis) in a tropical catchment

This study investigates basin-scale hydrologic implications of the replacement of forest-dominated land cover by rubber plantations in Montane Mainland Southeast Asia. The paper presents a new method for estimating the water demand of rubber and consequently water losses to the atmosphere through rubber evapotranspiration (ET). In this paper we argue that rubber ET is energy-limited during the ...

Improving West African rice production with agricultural water management strategies

The populations of West African countries continue to grow at rates exceeding three per cent per year. The international food price spike of 2008 focused attention on the risks to national security and livelihoods associated with importing significant quantities of food; and government and donor investment strategies now focus on ensuring national food security. Since rice is a key staple crop ...

Measuring infiltration rate and hydraulic conductivity in a dry well in a thin overburden

IInfiltration rate and hydraulic conductivity are immensely important parameters for evaluating the hydrology of subsurface environments. Specifically, in disposal wells schemes and in artificial recharge plans both properties must be correctly assessed to better analyze the performance of these installations. In a new research, tanker water and rainfall runoff were injected into a 22.5 m deep ...
