Assessing cost-effectiveness of land management measures to restore forest ecos...
Faria, Beatriz; Nunes, João Pedro; Baartman, Jantiene E.M.; Dias, Luís; Wu, Jinfeng; Prats, Sergio A.Forest fires strongly disturb key hydrological ecosystem services, such as soil protection, streamflow regulation and clear water provisioning, which can affect ecosystems and communities in burnt areas and downstream. Post-fire soil and water conservation (SWC) measures can be expensive, and their effectiveness depends on multiple factors such as the nature of the measures, the targeted areas, and the extent o...
Decision-making criteria to shape mulching techniques for fire-prone landscapes.
Petratou, Dafni; Nunes, João Pedro; Guimaraes, Maria Helena; Prats, SergioContext Wildfires have severe impacts on landscapes’ hydrological and sediment processes. They are linked to events such as flash floods and droughts, and high erosion rates which lead to loss of soil organic matter and detachment of seeds and seedlings. Mulching is an effective measure implemented directly after a fire to reduce soil erosion and increase soil water retention. However, its implementation has pr...
Impact of nature-based solutions on sustainable development goals in Mediterran...
Rodrigues, Miguel; Dias, Luís Filipe; Nunes, João PedroMediterranean agroecosystems' vulnerability to hydroclimatic extremes threatens their resilience and sustainability. Nature-based Solutions present a sustainable strategy to address global challenges. This meta-analysis of 70 studies developed in Mediterranean climates identified solutions to improve soil health and water quality in agroecosystems by estimating their effects on soil organic matter, organic carb...
Assessing post-fire water quality changes in reservoirs: Insights from a large ...
Nitzsche, Niels; Nunes, João Pedro; Parente, JoanaWildfires in the Mediterranean basin, especially in Portugal, have increased in extent and frequency over the last few years. One of the impacts of wildfires on humans and ecosystems is on the water quality of surface waters. Ashes and increased erosion rates might, for example, change oxygen levels and elevate the influx of sediments, nutrients, or other water quality-related components like metals and polycyc...
Intra-annual sediment dynamic assessment in the Wei River Basin, China, using t...
Wu, Zhenni; Baartman, Jantiene E.M.; Nunes, João Pedro; López-Vicente, ManuelHydrological and sediment dynamics have changed considerably on the Chinese Loess Plateau during the last six decades due to large scale land use changes and numerous water regulation actions. Understanding the mechanism of sediment transport change and its effects is of great importance to food and environmental security. Numerical approaches are useful to map and assess spatio-temporal patterns in sediment dy...
Assessing the climate change adaptability of sustainable land management practi...
van der Laan, Esther; Nunes, João Pedro; Dias, Luís Filipe; Carvalho, S.C.P.; Mendonça dos Santos, FrancianeIn Mediterranean catchments, such as the Sorraia catchment in Portugal, it is expected that climate change will increase drought stress and the deterioration of water quality in reservoirs. Sustainable land management (SLM) practices are seen as an adaption measure for those problems, but the effectiveness on improving climate change impacted water availability and quality on catchment scale is still poorly und...
Optimizing Reservoir Water Management in a Changing Climate
Beça, Pedro; Rodrigues, António C.; Nunes, João Pedro; Diogo, Paulo; Mujtaba, BabarOne of the UN agenda 2030 Sustainable Development goals is associated with water availability and its sustainable management. The present study intends to improve multipurpose reservoir management under climate change scenarios in water scarce regions such as the Mediterranean. Implemented methods include the sequential use of climate model results, hydrological modelling, and reservoir water balance simulation...

Testing simple approaches to map sediment mobilisation hotspots after wildfires
Parente, Joana; Nunes, João Pedro; Baartman, Jantiene; Föllmi, DanteBackground. The models currently used to predict post-fire soil erosion risks are limited by high data demands and long computation times. An alternative is to map the potential hydrological and sediment connectivity using indices to express the general properties of the burnt landscape. Aims. In this study, we aimed to answer the question: Do these tools identify post-fire sediment mobilisation hotspots? Metho...
