Act Ammonia and Livestock Farming (WAV) (INSPIRE)

These are areas in the province of Overijssel which are sensitive to acidification. The data is used when delivering to the European INSPIRE Directive. The highly sensitive areas for ammonia have been designated on the basis of Article 2(1) of the Ammoniak and Livestock Farming Act (WAV). This law protects highly sensitive areas from ammonia emissions caused by livestock farms. Under this law, Provincial States have designated areas that are considered to be very vulnerable. In these areas and in a zone of 250 meters around this area, expansion or the new establishment of livestock farms is limited. When the law was introduced in 2002, the areas susceptible to acidification were used within the Provincial Ecological Main Structure (EHS). Following the legislative change in 2007, these areas were restricted to the very sensitive areas. The new WAV stipulates that provincial states of the provinces must designate the most vulnerable areas. The criteria used are set out in the explanatory memorandum to the PS Decision (2007/053405). The criteria relate to the size and ecological value of the area sensitive to ammonia. In a separate relational table, under the name wav_afweightingcrit, are the ecological research results that played a role in this assessment. An important criterion for these areas is that they are located within the Ecological connection zone. The re-limitation of the EHS on 3 July 2013 and the partial revision of 2 September 2013 have led to a change in the limits of the highly sensitive areas.本数据集涵盖荷兰上艾瑟尔省（Overijssel）内对生态酸化敏感的区域，相关数据用于符合欧盟《空间信息基础设施指令》（INSPIRE Directive）的成果提交规范。高氨敏感区域系依据《氨与畜牧法》（Wet Ammoniak en Veehouderij, WAV）第2条第1款划定。该法案旨在保护此类高敏感区域免受畜牧养殖场产生的氨排放侵扰，根据法案要求，各省议会划定了被认定为极生态脆弱的区域。在上述区域及其周边250米缓冲范围内，畜牧养殖场的扩建与新建均受到限制。2002年该法案首次颁布时，酸化敏感区域被纳入省级生态主框架（Provincial Ecological Main Structure, EHS）；2007年立法修订后，此类区域的范围被收紧为极敏感区域。新版WAV规定，各省份的省议会须划定最具生态脆弱性的区域，划定标准已在2007/053405号省议会决议的解释性备忘录中予以明确，该标准涵盖氨敏感区域的规模与生态价值两项核心维度。在一份名为wav_afweightingcrit的独立关联数据表中，收录了本次评估所依托的生态研究成果。此类区域的一项重要判定条件为：其须处于生态连接带范围内。2013年7月3日对EHS的范围重新限定，以及2013年9月2日的部分修订，导致高敏感区域的划定范围发生调整。
