Climate Vulnerability Assessment: Irrigated Lucerne

The **Climate Vulnerability Assessment** was designed to provide an overview of the impact of future climate change on all stages of production for the commodities and biosecurity risks assessed. The project used multicriteria analysis (MCA) models to produce assessments for the commodities and biosecurity risks in a consistent and comparable way, and a framework was developed to provide a rigorous, flexible and transparent process for assessing vulnerabilities and opportunities to climate change. Details of the approach and the climate data used in the assessments can be found in the [Methodology Report](https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment/publications-and-reports) which also details model exclusions and assumptions.\r\n\r\nAssessments were undertaken on commodities grouped into 6 nodes: *Horticulture and Viticulture*, *Broadacre Cropping*, *Forestry*, *Extensive Livestock*, *Marine Fisheries*, as well as for a set of biosecurity risks related to these primary industry sectors. The [Summary Report](https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment/publications-and-reports) gives details of the chosen commodities and biosecurity risks and summarises the high-level results.\r\n\r\nResults Reports for each commodity and biosecurity risk are being released. Visit the [project's web pages](https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment) to access these reports and for further information.\r\n\r\nThis dataset contains maps of modelled climate suitability for the **irrigated lucerne** model in the Broadacre Cropping node of the DPIRD Climate Vulnerability Assessment. Maps are provided (in GeoTIFF format) for each element of the model: the overall climate suitability, climate suitability maps for each phenophase and also for each phenophase/climate variable combination in the model. Data is provided for each of the eight global climate models (GCMs) used in the project, as well as the climate suitability derived from historical observations, along with the ensemble median for each map.

**《气候脆弱性评估》（Climate Vulnerability Assessment）旨在系统概述未来气候变化对所评估大宗商品各生产环节的影响，以及相关生物安全风险。本项目采用多准则分析（multicriteria analysis, MCA）模型，以统一且可对比的方式完成各类大宗商品与生物安全风险的评估，并构建了一套严谨、灵活且透明的框架，用于研判气候变化带来的脆弱性与发展机遇。本次评估的方法细节与所用气候数据可参阅[方法学报告](https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment/publications-and-reports)，该报告同时详述了模型的排除规则与假设前提。

本次评估覆盖划分为6个评估类别的大宗商品：*园艺与葡萄栽培*、*大田作物种植*、*林业*、*粗放畜牧*、*海洋渔业*，以及与上述初级产业领域相关的各类生物安全风险。[总结报告](https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment/publications-and-reports)详述了入选的大宗商品与生物安全风险，并汇总了核心结果。

针对各大宗商品与生物安全风险的结果报告已陆续发布。请访问[项目官方网页](https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment)获取相关报告及更多信息。

本数据集包含DPIRD气候脆弱性评估中大田作物种植类别下**灌溉紫花苜蓿（irrigated lucerne）**模型的模拟气候适宜性地图。本次为模型各要素提供了GeoTIFF格式的地图文件：包括整体气候适宜性图、各物候期（phenophase）的气候适宜性图，以及模型中各物候期/气候变量组合对应的适宜性图。数据集涵盖项目所用的8个全球气候模型（global climate models, GCMs）的相关数据，同时包含基于历史观测数据推导的气候适宜性数据，以及每张地图的集合中位数结果。
