To augment the understanding of EBW under seasonally changing conditions, this study aims to investigate weathering processes under anoxia to hypoxia in corrosive bottom waters, which reflect late summer conditions in the Baltic Sea. Dunite and calcite were added to sediment cores retrieved from Eckernförde Bay (Western Baltic Sea) with a constant flow-through of deoxygenated, CO2-enriched Baltic Sea bottom water. The addition of both materials increased benthic alkalinity release by 2.94 μmol cm−2 d−1 (calcite) and 1.12 μmol cm−2 d−1 (dunite), compared to the unamended control experiment. These excess fluxes are significantly higher than those obtained under winter conditions. The comparison with bottom water oxygen concentrations emphasizes that highest fluxes of alkalinity were associated with anoxic phases of the experiment. An increase in Ca and Si fluxes showed that the enhanced alkalinity fluxes could be attributed to calcite and dunite weathering. First order rate constants calculated based on these data were close to rates published in previous studies conducted under different conditions. This highlights the suitability of these proxies for mineral dissolution and justifies the use of these rate constants in modeling studies investigating EBW in the Baltic Sea and areas with similar chemical conditions. Generally stable pH profiles over the course of the experiment, together with the fact that the added minerals remained on the sediment surface, suggest that corrosive bottom waters were the main driving factor for the dissolution of the added minerals. These factors have important implications for the choice of mineral and timing for EBW as a possible marine carbon dioxide removal method in seasonally hypoxic to anoxic regions of the Baltic Sea.","PeriodicalId":33632,"journal":{"name":"Frontiers in Climate","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139683720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional agriculture, deeply rooted in the region's history and culture, is particularly vulnerable to these changes. This study investigates the adaptation strategies of traditional agricultural farmers to climate change using southeast Nigeria as a microcosm of the broader challenges facing sub-Saharan Africa.Multistage sampling procedure was used to select 75 farmer group leaders in the study region. Cross-sectional data were collected through semi-structured interview schedules and focus group discussions. Data were analyzed using descriptive statistics and principal component analysis using Varimax rotated matrix.Findings showed that farmers rely on face-to-face discussions with neighbors (76.0%), fellow farmers (66.7%), and radio (54.7%) as their primary sources of information on climate change. Results showed that traditional adaptation practices such as use of organic manure (x¯ = 3.89), traditional organic composting (x¯ = 3.80), afforestation (x¯ = 3.71), agroforestry (x¯ = 3.61) were the topmost traditional agricultural practices use to cushion the effect of climate change. Conserving the overall soil health, soil moisture retention, reducing CO2 emissions and maintaining crop productivity were the major reasons for using the traditional approaches. Climate-induced drought and high cost of accessing weather information (x¯ = 1.93), and inadequate funding (x¯ = 1.92), among others were the key constraints to adaptation.Results showed that farmers prioritize agronomic manipulation and integrated research approaches as key strategies to adapting traditional agriculture to climate anomalies. Although farmers used their indigenous practices, continuous learning and improvement through capacity-building workshops and progress monitoring are essential for effective climate change adaptation. Policymakers should invest in promoting indigenous knowledge, provide access to credit for climate-resilient infrastructure, promote climate-smart agricultural practices and foster collaborative research as the cornerstone for sustainable rural development.","PeriodicalId":33632,"journal":{"name":"Frontiers in Climate","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140475993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to provide a comprehensive review of the recent advances, gaps and challenges in the provision of climate services over the region, for each of the components of the Global Framework for Climate Services. The study explores various milestones that have been achieved toward climate service delivery. The achievements include improvement of station network coverage, and enhancing the capacity of member states to utilize various tools in data analysis and generate routine climate products. The advancement in science, and availability of High-Performance Computing has made it possible for forecast information to be provided from nowcasting to seasonal timescales. Moreover, operationalizing of the objective forecasting method for monthly and seasonal forecasts has made it possible to translate tercile forecasts for applications models. Additionally, innovative approaches to user engagement through co-production, communication channels, user-friendly interfaces, and dissemination of climate information have also been developed. Despite the significant progress that has been made in the provision of climate services, there are still many challenges and gaps that need to be overcome in order to ensure that these services are effectively meeting the needs of users. The research of the science underpinning climate variability, capacity building and stakeholder engagement, as well as improved data management and quality control processes are some of the gaps that exist over the region. Additionally, communication and dissemination of climate information, including timely warnings and risk communication, require improvement to reach diverse user groups effectively. Addressing these challenges will require strengthened partnerships, increased investment in capacity building, enhanced collaboration between the climate information producers and stakeholders, and the development of user-friendly climate products. Bridging these gaps will foster greater resilience to climate-related hazards and disasters in the Greater Horn of Africa and support sustainable development in the region.","PeriodicalId":33632,"journal":{"name":"Frontiers in Climate","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140485128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of this hydropower development involves freshwaters that cross national borders raising complex issues in international law, a situation exacerbated by growing economic, environmental, and regional security pressures. In such a context, where conflicts-of-use are almost certain to arise, it is essential to understand the rules that apply so as to enhance opportunities for enhanced transboundary water cooperation. This paper examines the rules of international water law and international economic law that apply to transboundary hydropower development, with a focus on China as one of the key actors in this field. The aim is to examine the regulatory interface of relevant legal frameworks with a focus on China's approach to transboundary hydropower development at home and abroad. While international economic—and more specifically international investment law—is not directly concerned with international water law, host states and foreign investors must be informed, and take into account, the legal obligations governing transboundary waters. China's position as a major water user (at home) and significant investor (abroad) on transboundary waters, makes it a unique case study for exploring the rules of international law that apply in two different regulatory settings. The work examines the rules of law in each of these domains and reveals the inapparent linkages across these seemingly unconnected areas of international regulation.","PeriodicalId":33632,"journal":{"name":"Frontiers in Climate","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139604297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
