Abstract Governments are increasingly committing to significant forest restoration. While carbon sequestration is a major objective, the case for restoration often includes benefits local communities. However, impacts of on hydrological services (e.g. flood and erosion risk, stream flow during dry periods) surprisingly poorly understood. Particularly limited information available passive tropical following shifting cultivation. The outcome depends trade‐off between improved soil infiltration...
This paper shares an early-career perspective on potential themes for the upcoming International Association of Hydrological Sciences (IAHS) Scientific Decade (SD). opinion synthesizes six discussion sessions in western Europe identifying three that all offer a different hydrological threats world faces and could serve to direct broader community: “Tipping points thresholds hydrology,” “Intensification water cycle,” “Water services under pressure.” Additionally, four trends were...
Land cover in areas undergoing long-term shifting cultivation typically represents a mosaic of agricultural fields, fallows different stages regrowth, remnant forest, and degraded grasslands. The Ankeniheny Zahamena corridor eastern Madagascar case point. Previous research revealed major differences hydrological response between forests, or reforested sites, We used these field data the physically-based RoGeR_Dyn model[1] to examine effects topography land on processes at...
It has been suggested that vigorous secondary tropical forests can have very high transpiration rates, but sap flow and stomatal conductance dynamics of trees shrubs in these are understudied. In an effort to address this knowledge gap, (thermal dissipation method, 12 trees) (porometry, six were measured for young (5-7 years) Psiadia altissima (DC.) Drake trees, a widely occurring species dominating regrowth following abandonment swidden agriculture upland eastern Madagascar. addition, (gs)...
The large areas being targeted for tropical forest restoration as part of the UN Decade on Ecosystem Restoration will have major consequences flow water through landscapes. Whilst prevailing mantra that ‘more implies less streamflow’ remains true in terms annual yields, we demonstrate opportunities increased tree cover to improve seasonal regimes streams, particularly baseflows, are important. We discuss several potential positive feedbacks hydrological processes at...
Governments are increasingly committing to significant ecological restoration. However, the impacts of forest restoration on local hydrological services surprisingly poorly understood. Particularly, limited information is available about tree planting soil infiltration processes and runoff pathways. Thus, we investigated saturated hydraulic conductivity (Ks) preferential flow pathways in three land-cover types: (i) Active Restoration, (ii) Degraded Land, (iii) Reference Forest, with...

ABSTRACT Intensified slash‐and‐burn cultivation and forest clearing have caused severe land degradation in the Khasi Hills (Meghalaya plateau, NE India). Despite very high annual rainfall, region faces water scarcity during dry season. Local initiatives aim to restore forests through assisted natural regeneration (ANR) this hydrologically poorly known area. As a first step towards assessing potential hydrological impact of regrowth ANR, we measured infiltrability at sites representing...
Abstract Slash‐and‐burn agriculture is an important driver of tropical forest loss and typically results in a mosaic land uses. However, there little quantitative information about the hydrological effects long‐term slash‐and‐burn how such mosaics affect rainfall‐runoff response at catchment scale. We monitored streamflow responses two points along perennial stream 31.7 ha eastern Madagascar that was previously between 1963 1972. Land cover 2015 consisted degraded grasslands, shrub tree...
<p>As in other parts of the Indian subcontinent, forests Meghalaya (NE India) provide an array environmental services but prevalence traditional slash-and-burn agriculture (locally called jhum) plus mining has led to severely degraded hillsides and a critical loss soil water storage opportunity groundwater recharge. As result, despite receiving some highest rainfall totals world (MAP up 11 m, 75% received between May September), plateau faces severe scarcity during five-month...
Land cover in catchments undergoing shifting cultivation typically represents a mosaic of agricultural fields, fallows different stages regrowth, remnant forest, and degraded grasslands. Although runoff responses the respective land-cover types are expected to differ, there is little quantitative information on how such land covers affects rainfall-runoff at catchment scale.From February 2015 2016, we measured rainfall, streamflow, plus plot-scale (saturation) overland flow (SOF), soil...
<p>In many tropical areas slash-and-burn agriculture is an important driver of forest loss. In where has been practiced for decades, land cover typically a mosaic patches remnant forest, fields under active cultivation, fallows in various stages regrowth (ranging from young shrub to semi-mature), and degraded fire-climax grasslands. Although runoff generation mechanisms are expected be different these patches, little quantitative information available this regard, particularly...
