Abstract:
... The mechanisms influencing livestock pricing in Kenya are well studied. The determinants of quality-based payments on markets in conflict-affected areas, however, are hardly documented. In this paper, we offer a deeper understanding of transitions towards quality-based payments from the perspective of livestock buyers in the Kerio-Valley, Kenya. The location is known for protracted communal confli ...

Abstract:
... Based on data obtained from ERA-20C during 1900–2010, this study statistically conducts spatiotemporal characteristics and relations between boundary layer height (BLH) and aridity index (AI) in East Asian drylands, thus originally understanding dry–wet changes from perspective of atmospheric boundary layer. A high (low) BLH generally coincides with regions that have small (large) AI. The annual v ...

Abstract:
... The dynamics of plant populations are often limited by the early stages in their life cycles. However, information regarding seed bank dynamics and how these may influence the whole life cycle of plant species is remarkably scarce or not considered explicitly. This lack of knowledge is due mainly to the challenges in quantifying seed vital rates. Studies of arid land plant species have historicall ...

Abstract:
... AIM: Plant–plant interactions are an important factor in structuring plant biodiversity. However, most studies on the impacts of plant–plant interactions on biodiversity focus on species richness and to a lesser extent on other facets of diversity. When other facets of biodiversity are considered, studies often include a limited set of environmental conditions. We aimed to quantify the impacts of ...

Abstract:
... Vegetation memory describes the effect of antecedent environmental and ecological conditions on the present ecosystem state and has been proposed as an important proxy for vegetation resilience. In particular, strong vegetation memory has been identified in dryland regions, but the factors underlying the spatial patterns of vegetation memory remain unknown. We aim to map the components and drivers ...

Abstract:
... Although fog is an important component of the hydrological cycle of drylands, its formation mechanisms are not fully understood leading to discrepancy of fog type classifications using different methodologies. Such discrepancies may result in under or over estimation of the potential impacts of global climate change on the ecohydrology of fog dependent ecosystems. To fill this knowledge gap, this ...

Abstract:
... The Central Asian dryland (CAD) and East Asian dryland (EAD) are typical drylands in the globe. They are characterized by less precipitation, with vulnerable and sensitive ecosystems. Although they are located in the heart of continent, precipitation in these regions has opposite patterns on the multi-decadal time scale. In this study, we focus on different responses of precipitation changes in th ...

Abstract:
... Almost one third of global drylands are open forests and savannas, which are typically shaped by frequent natural disturbances such as wildfire and herbivory. Studies on ecosystem functions and services of woody vegetation require robust estimates of aboveground biomass (AGB).
