<p>In developing the methodology for indicator 6.6.1 UNEP set up a technical expert group. This group provided inputs into the development of the monitoring methodology. A first draft (Tier III) methodology was piloted in 2017 and sent to all UN Member States accompanied with relevant capacity support materials. A limited number of Member States (19 per cent) submitted data to UNEP after a period of 8 months. The data that was received was of poor quality and coverage. Countries cited a lack of data to report, and neither time nor resources to initiate new ecosystem monitoring.</p>
<p>Following on from the global piloting and testing phase, and to address a known global data gap for the indicator, the methodology was revised to incorporate data on water-related ecosystem derived from satellite-based Earth observations. UNEP engaged with a series of partners working with global data products considered relevant and suitable for the indicator. The assessment of global data sources considered data quality, resolution, frequency of measurements, global coverage, time series, and scalability (i.e. disaggregated data at national and sub-national levels). The result was a methodology that is statistically robust producing internationally comparable data without being too onerous for countries to report on. The technical expert group was consulted on the updated methodology before submission to the IAEG-SDG for approval. </p>
<p>At the 7th IAEG-SDG meeting in April 2018, the indicator methodology was approved and classified as Tier II. Shortly afterwards, in November 2018, it was reclassified to a Tier I indicator methodology. The Tier I classification means that the indicator is conceptually clear, has an internationally established methodology and standards are available, and data are regularly produced by at least 50 per cent of countries and of the population in every region where the indicator is relevant.</p>
<p>Throughout 2019, UNEP continued to work with its partners to improve the globally available datasets relevant to SDG indicator 6.6.1 and the measurement of changes occurring to different types of water-related ecosystem. As such, this methodology was updated in March 2020 to include more detailed information about the approach used to obtain satellite-based Earth observation data with regard to the sub-indicators.</p>

<p> Методология была протестирована на протяжении двух пилотных этапов. Первый из них включал разработку методологии при участии стран, в результате чего был разработан первый проект методологии, который был рассмотрен и доработан целевой группой. В начале 2016 года проект методологии был апробирован в пяти странах в период с апреля по ноябрь 2016 года на семинарах в Иордании, Нидерландах, Перу, Сенегале и Уганде. В каждой из этих стран были задействованы различные участники из национальных организаций и государственных секторов для организации широкой обратной связи по обсуждению технической пригодности проекта методологии. </p>
<p> В ходе пилотных страновых проверок методологии в 2016 году с НСУ каждой из 5 стран проводились консультации и они участвовали в процессе. Во время сбора пилотных методологических данных в 2017 году первоначальный запрос на предоставление данных был передан всем НСУ. Кроме того, в октябре 2017 года национальные данные по пространственной протяженности открытой воды (полученные на основе наблюдений за Землей) были предоставлены 188 странам напрямую через их НСУ (см. дополнительную информацию выше). </p>

<h1> Доступность данных </h1>
<h2> Описание: </h2>
<p> Для субпоказателей 1 и 2 доступны ежегодные данные. По субпоказателям 3, 4 и 5 данные уже доступны из некоторых стран, и национальным властям следует усилить мониторинг и отчитываться о мероприятиях по расширению доступности данных по этим трем субпоказателям. </p>
<p> Сбор данных по всем субпоказателям был включен в сбор данных по странам в 2017 году; однако данные все еще находятся в процессе валидации. Кроме того, за период 2001-2015 годов были собраны национальные пространственные данные по 188 странам в поддержку субпоказателя 1. Данные по всем 5 субпоказателям предоставляются в СОООН каждые 5 лет. </p>
<h2> Временные ряды: </h2>
<p> Отчетность по этому показателю будет формироваться по годовому циклу. </p>
<h2> Дезагрегирование: </h2>
<p> Показатель 6.6.1 можно дезагрегировать по каждому субпоказателю. Все субпоказатели также могут быть дезагрегированы по разным пространственным масштабам, то есть по национальному, бассейновому типу и модели экосистемы. </p>
