ABSTRACT Freshwater biodiversity is the fastest declining part of global biota, threatened by multiple stressors including habitat loss and fragmentation, climate change, invasive species, water pollution, abstraction humans. A multitude recent agenda‐setting publications have pointed out key objectives goals for addressing this freshwater crisis, but important gaps must be overcome to reach ambitious conservation targets. In perspective, we complement these high‐level papers in highlighting knowledge, governance, implementation. This gap‐oriented approach designed facilitate meaningful action missing ‘pieces’ process, their connection existing emerging solutions literature. We derive 13 overarching from a conference session informal synthesis literature catalyse research, advocacy, meet post‐2020 Kunming–Montreal Global Biodiversity Framework (GBF). Key include inventory data on biodiversity, collating mobilizing evidence practice, improving coordination ecological governance at scale —including within across catchments—and navigating trade‐offs between economic development, resource consumption, priorities biodiversity. Finally, apply language describing GBF conservation, point which may help address gaps. Major themes that use Nature‐based Solutions Other Effective Area‐based Conservation Measures (OECMs), navigation management human environmental needs, co‐production knowledge with Indigenous local people other stakeholders, integration research aquatic terrestrial ecosystems, funding policy mechanisms support monitoring hydrological scales.

Conserving Freshwater Ecosystems in India: A call to action

Aquatic Conservation Marine and Freshwater Ecosystems, Год журнала: 2024, Номер 34(5)

Опубликована: Май 1, 2024

Abstract India boasts of a vast freshwater resource network (rivers, wetlands, and groundwater), which has unique ecological, social economic values associated with it. Despite their importance for both people biodiversity, its ecosystems (FWEs) are heavily impacted through multiple factors such as pollution, overexploitation, habitat loss/modification climate change. is also among the hotspots water overuse that caused serious decline in availability. Given healthy FWEs lie at centre supporting country's ecology, health, economy, livelihoods ultimately achieving policy goals, it crucial holistic focused efforts made to protect, conserve, restore all types FWEs. We call an urgent greater focus on implementing conservation actions suggest following strategy enhance conservation: (1) establishing shared vision national scale, (2) developing including goals within global efforts, (3) conducting simultaneous action planning regional scales (4) bridge implementation gap by strengthening key enabling conditions: i) mainstream FWE existing governance instruments, ii) secure sustainable funding, iii) improve data access knowledge translation; iv) create awareness around FWEs; v) facilitate collaboration actors.

Numerical analysis of an extended mean field game for harvesting common fishery resource

Computers & Mathematics with Applications, Год журнала: 2024, Номер 165, С. 88 - 105

Опубликована: Апрель 22, 2024

Resource harvesting in inland fisheries during a single fishing season is mathematically modeled based on an extended mean field game played by many anglers. The rate of each angler depends that the others through interaction. Each wants to maximize utility, while resource overexploitation effectively penalized incentives for conservation. Anglers' activities are represented controlled jump processes arising as unique nonlinearity game. Solving reduces resolution forward-backward system containing Hamilton–Jacobi–Bellman and Fokker–Planck equations coupled rate. average total visiting time per obtained byproduct from system, which used investigate scheme license fee fisheries. A finite difference method proposed numerically compute Picard iteration. convergence numerical solution equation analyzed discontinuous viscosity solutions. Finally, we specify fish population dynamics data major fishery Plecoglossus altivelis 2023 Japan. Computational examples presented analyze our mathematical model.

Saving India’s freshwater biodiversity

Biodiversity, Год журнала: 2024, Номер 25(3), С. 197 - 199

Опубликована: Июль 2, 2024

Freshwater biodiversity faces a critical situation globally. Current efforts to protect and conserve India's freshwater have been insufficient in light of emerging challenges. To address this, we propose 14 science-based policy-backed recommendations aimed at achieving long-term protection Indian ecosystems conservation goals. Managers nodal agencies expressed support for implementing these recommendations. The Wildlife Institute India has recently launched pioneering master's degree programme ecology instituted scholarships local citizens known as 'Guardians the Ganga', who are actively engaged conserving along Ganga River under auspices 'Biodiversity Conservation Rejuvenation' project sponsored by National Mission Clean Ganga. These initiatives align closely with our proposed Implementing timely policymakers is crucial safeguarding biodiversity.

Spatial Distribution Patterns and Beta Diversity of Fish Communities in a Tropical River Basin of Deccan Plateau

Ecohydrology, Год журнала: 2024, Номер unknown

Опубликована: Сен. 24, 2024

ABSTRACT Riverine ecosystems exhibit significant spatial variations in their communities, and understanding of these variances is vital to comprehend the mechanisms that maintain biodiversity. This study was conducted understand pattern distribution beta diversity fish communities Bhima River basin Deccan Plateau region India. Fish data from 59 sites across 11 rivers were collected, pair‐wise β Dissimilarity site‐wise local contribution (LCβD Sorensen ) its components Turnover LCβD Nestedness calculated. Power function regression analysed decay community similarity with geographical environmental distances. Redundancy analysis performed investigate relationship between variables. Results indicated species richness declined increasing longitude west east. A negative observed . formed Ո‐shaped curve at both ends gradient, while values exhibited Ս‐shaped curve. No difference mean observed. The distance distances follows power law shape, slope this flattened distance. Precipitation, topography, temperature variation dissolved oxygen played a pivotal role shaping assemblages. provides insight into basin, which will be helpful ordination biodiversity riverine ecosystem region.

Proposal on Species‐Specific Synergistic Conservation Measures for Critically Endangered Gharial (Gavialis gangeticus)

Aquatic Conservation Marine and Freshwater Ecosystems, Год журнала: 2024, Номер 34(11)

Опубликована: Ноя. 1, 2024

ABSTRACT The gharial ( Gavialis gangeticus ), a critically endangered freshwater reptile endemic to the Indian subcontinent, faces severe threats from various anthropogenic stressors. Despite positive conservation efforts, holistic approach is essential for improved outcomes. This involves (1) identification of new priority sites, (2) establishment populations outside protected areas, (3) interlinking ecosystem processes, (4) conducting census annually, (5) efficient use digital technology, (6) adoption best management practices mitigate threats, (7) assessment inbreeding depression in gharial, (8) rescue and rehabilitation training local communities, (9) interstate trans‐boundary commission (10) survey on socio‐economic status communities. Implementing proposed synergistic measures will not only strengthen efforts but also enhance livelihoods ensuring sustainable future this species.
