This paper presents an open access approach to map climate risk and vulnerability using Birmingham, the UK’s second city as a case study. A Climate Risk and Vulnerability Assessment (CRVA) was co-created with Birmingham City Council to ensure the approach supports the organisation’s needs, now and in the future. Using Geographic Information System (GIS) software, eleven geospatial datasets expressing physical, environmental, and social variables were combined to characterise holistic climate risk and vulnerability relative to the city boundary, where the higher the score, the higher the combined climate risk and vulnerability of an area. The resulting map (i) transparently evidences climate impacts across the city and the underpinning drivers, (ii) supports the prioritisation of interventions for those areas most at risk or vulnerable to climate change, (iii) supports the implementation of more climate-resilient development, and (iv) can be managed by stakeholders going forward for monitoring and evaluation purposes. While there are inevitable limitations in what can be achieved with an open access approach, the current CRVA can be considered a ‘minimum viable product’ that can be developed and improved iteratively in climate adaptation planning cycles. Its results can feed into broader policy agendas, such as national adaptation plans, adaptation reporting, just transition, and biodiversity net gain.</div></div>","PeriodicalId":51332,"journal":{"name":"Climate Services","volume":"36 ","pages":"Article 100521"},"PeriodicalIF":4.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Frequent changes in soil and water resources have significant impacts on regional ecosystems. However, research on the ecosystem water yield function of EBNSTM is relatively limited; additionally, the spatiotemporal variations in the water supply function based on land use changes have not been sufficiently elucidated. This study aimed to explore the land use changes and the spatial variability of water supply service functions in the region at the macro level and uses the land transfer matrix as an important tool to study the changes in land use in the different years of 2000, 2005, 2010, 2015, and 2020. Using the InVEST model, we conducted a quantitative assessment and comprehensive study on the water supply function of EBNSTM across the aforementioned years. Additionally, the study delved into the structure of ecosystem service functions, alongside investigating the spatial and temporal variability of ecosystem services under the multi-scale units of administrative divisions, ecological zones, and land classes. We found that during the 20-year period, the area of construction land of EBNSTM increased by 1089 km², with the highest dynamic change rate of 4.09 %; 2015–2020 period was the most drastic period of change for each land use type. The average multi-year depth of water production was 87.49 mm, totaling 71.59 × 10⁸ m³. The spatial distribution pattern of the water supply function in the study area during the last 20 years consistently exhibited a distinct pattern: mountainous areas displayed the highest water supply capacity, followed by oases, and deserts ranked the lowest. Further, the water supply service function within the study area is currently experiencing a modest rate of increase. The rate of change in water supply depth was 2.76 mm/a, while the rate of change in water supply volume was 0.47 × 10⁸ m³/a. Areas with enhanced water supply capacity are mostly distributed in the southeast of EBNSTM, whereas the northwest, encompassing the mountainous areas, exhibited a declined water supply capacity. Between 2000 and 2020, the water supply capacity in the study area was ranked as follows: woodland &gt; grassland &gt; unutilized land &gt; cultivated land &gt; urban construction land, with woodland displaying the strongest water supply capacity. When woodlands, grasslands, and croplands were converted to other land use types, their water supply functions generally decreased, and vice versa. Our findings provide a scientific basis for the sustainable management of water and soil resources in EBNSTM.</div></div>","PeriodicalId":51332,"journal":{"name":"Climate Services","volume":"36 ","pages":"Article 100519"},"PeriodicalIF":4.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142327829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study intends to identify small-scale farmers’ adaptation options, their perception and existing barriers in northern Ethiopia. It is based on an analysis of cross-sectional data collected from 193 randomly selected farm household heads. A multivariate probit model was employed to analyze the factors influencing farmers’ climate change adaptation choices. Constraint Facing Index (CFI) technique was also constructed to identify the existing barriers. The findings indicate that a significant number of farmers (91.2%) reported a trend toward rising temperatures. Similarly, 86.01% of the farmers indicated that the perceived rainfall trend has decreased. Adjusting planting dates (56.5%), integrated soil fertility management practices (47.7%), early maturing crop varieties (53.4%), terracing for soil and water conservation (54.9%), and income diversification (55.4%) were the most common climate change adaptation options practiced by farm households in the study area. Some of these adaptation options have significant and complementary relationships. The farmer’s choice of adaptation option was highly constrained by institutional factors and all these identified factors can be possibly addressed through a better institutional service provision system, for a better farm-level adaptation while considering demographic characteristics as well.</div></div>","PeriodicalId":51332,"journal":{"name":"Climate Services","volume":"36 ","pages":"Article 100517"},"PeriodicalIF":4.0,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142319109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyze the meteorological conditions leading to first occurrences of such hot events and their common atmospheric patterns.

Weather and climate conditions affect grapevine development in cultivars: anticipating the atmospheric variables in the coming weeks and months is thus relevant for effectively managing vineyards, as impacts will be felt in wine production, biodiversity, and a wide range of related aspects. The operational service was co-developed with two types of users: impact modellers, who are the intermediary users incorporating climate forecast outputs in phenological and disease models, and end-users from the wine sector with vineyards in various European locations. For the operational service, sub-seasonal and seasonal climate forecasts were tailored considering their needs. The initial steps of the co-production process identified relevant decisions for which the service was essential and co-defined effective ways to deliver the climate information. Afterwards the climate forecasts outputs were integrated with impact model data. Substantial efforts were directed at the harmonisation of climate services information with the decision-making system of end-users. Because end-users need to navigate, comprehend, and select from various alternative options amidst uncertainty, significant emphasis has been placed on crafting the visual representation of the climate service, incorporating interactive elements, and cognitive considerations, thereby enhancing the overall user experience.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Practical implications&lt;/h3&gt;&lt;p&gt;Weather and climate conditions affect the development of cultivars: phenological stages, disease risk, or wine quality.
