Building on farmer’s agroecological knowledge to design environmental-friendly agricultural systems is crucial given the environmental impact of industrial agriculture. We investigated the drivers of farmers’ knowledge of agrobiodiversity management and analyzed how farmers’ knowledge and their current farming contexts may guide future farming systems in sub-humid (Bassila) and semi-arid (Bouko...

The geometry of foreland basins is controlled by a dynamic balance between thrust-belt migration, fl exural subsidence, and fl uvial deposition. To improve our ability to quantify the relationships between tectonics, climate, and foreland basin geometry, I developed analytic solutions for basin topography and stratigraphy using a classic two-dimensional mathematical model of foreland basin evol...

Despite the fact that gross primary productivity (GPP) and water use efficiency (WUE) have been widely used as indicators to evaluate water-carbon cycle, uncertainties exist in patterns of GPP WUE responses climate variability along different aridity gradients. In this study, index was divide China into four arid-humid zones. The spatiotemporal multiple vegetation types response change under zo...

Vegetation change, whether it be of anthropogenic or climatic origin, can have dramatic effects on landscape form, processes and sediment yield. General conceptual models for relationships between climate, vegetation and sediment yield exist for whole landscapes, but no rigorous analysis of the effects of vegetation change on sediment transport, in the absence of overland flow, has been done fr...

Abstract Drought is the most important factor limiting growth and production of wheat in China. Arid semi-arid regions high water consumption agricultural sector have led to various deficit irrigation strategies. The effect hydrological process on yield has been evaluated rainfed cultivation for three climatic stations Gansu Province, Yellow River Valley, A general framework was provided arid r...

Based on the data from China’s second national soil survey and field observations in northwest China, we estimated soil organic carbon (SOC) storage in China and investigated its spatial and vertical distribution. China’s SOC storage in a depth of 1 meter was estimated as 69.1 Pg (10 g), with an average density of 7.8 kg m. About 48% of the storage was concentrated in the top 30 cm. The SOC den...

The dry forests of northeastern Brazil are found near the coastal zone and on low, isolated mountains inland amid semi-arid vegetation. The floristic composition of these dry montane forests, as well as their relationship to humid forests (Atlantic forest sensu stricto) and to the deciduous thorn woodlands (Caatinga sensu stricto) of the Brazilian northeast are not yet well known. This paper so...

North Africa features some of the most frequently burnt biomes on Earth, including semi-arid grasslands Sahel and wetter savannas immediately to south. Natural fires are fuelled by rapid biomass production during wet season, its desiccation dry season ignition frequent lightning strikes. Today, fire activity decreases markedly both north Sahel, where rainfall is extremely low, almost eliminatin...
