AbstractEvaluating the current state of hydrologic processes in urban and semi-urban areas is an essential part ensuring sustainable management water preventing emergencies extreme events. This study evaluated effects land use cover (LULC) change on runoff Waterford River Watershed (WRW), located eastern province Newfoundland Labrador (NL), Canada. The Regional Hydro – Ecological Simulation System (RHESSys), a GIS-based hydro-ecological model, was used new urbanistic approach to simulate increasing impervious as well reducing green areas. increase hypothetical peak flows had direct relationship with reduction pervious watershed. most sizeable flow increases were observed periods April May October December. emphasizes importance using prominent network structures or retention when allocation for residential commercial increase.RésuméAfin d’assurer une gestion durable des ressources hydriques et d’éviter les urgences liées aux évènements catastrophiques, l’examen conditions actuelles processus hydrologiques dans milieux urbains périurbains est nécessaire.

How much of the economy is focused on protecting, rehabilitating, or managing environment?To answer this question, we develop a proof-of-concept environmental activity account to quantify goods and services sector (EGSS) in United States.Methodologically, employ satellite approach similar method used by US Bureau Economic Analysis (BEA) other sectors (e.g., Outdoor Recreation Account, Marine Economy Account) while following accounting principles methods outlined SEEA Central Framework (SEEA-CF).This draws detailed internal supply-use data, drawn primarily from Census's Industry Product data along with supplemental sources.Overall, estimate gross output EGSS was $725 billion 2019, about 1.9% total economy.Government expenditures (across all levels) comprise substantial portion US, as public accounted for 27% ($197 billion) 2019.Although these estimates are still preliminary not official statistics, goals research provide new insights into classification measurement challenges producing accounts more generally, also documenting gaps issues context specifically.

In this study, tree selection/plantation DSS (Decision Support Systems) were reviewed and assessed based on essential objectives in the available literature. We existing using multiple data sources online resources such as web interfaces. compared DSS, focusing primarily five primary which may address when it comes to selection, including a) Climate resilience, b) Infrastructure/Space Optimization, c) Agroforestry, d) Ecosystem services, e) Urban sustainability. resilience of species urban sustainability is addressed relatively less systems, can be holistically internalized future tools Based review, DNN (Deep Neural Networks) recommended achieving trade-offs between complex maximizing ecosystem climate species, maintaining other benefits.

Quercus alba L., also known as white oak, eastern or American is a quintessential North species within the oak section (Quercus) of genus Quercus, subgenus Quercus. This plays vital role keystone in forests and significant local regional economies. As long-lived woody perennial covering an extensive natural range, Q. alba’s biology shaped by myriad adaptations accumulated throughout its history. Populations are crucial repositories genetic, genomic, evolutionary insights, capturing essence successful historical ongoing responses to contemporary environmental challenges Anthropocene. intersection offers exceptional opportunity integrate genomic knowledge with discovery climate-relevant traits, advancing tree improvement, forest ecology, management strategies. review provides comprehensive examination current understanding biology, considering past, present, future research perspectives. It encompasses aspects such distribution, phylogeny, population structure, key adaptive traits cyclical conditions (including water use, reproduction, propagation, growth), well species’ resilience biotic abiotic stressors. Additionally, this highlights state-of-the-art resources available for genus, including alba, showcasing developments genetics, genomics, biotechnology, phenomics tools. overview lays groundwork exploring elucidating principles longevity plants, positioning emerging model species, ideally suited investigating traits.
