Two years on since the One Planet Summit, 80 percent of the US$19 billion pledged towards the Great Green Wall Accelerator has been programmed across the 11 African nations that are part of the initiative. However, continued political leadership and country ownership, targeted action at all levels, and strengthened institutional arrangements are required to realize the vision of this Africa-led movement.

The 2022 reporting process has now concluded. We would like to thank all Parties for their efforts to submit national reports and are delighted with their active engagement in the process. We are now analyzing the reported data in preparation for CRIC21. PRAIS 4 is now closed for further submissions and submitted national reports can be found in Country Profiles. Additional national reports can be submitted on request via reporting@unccd.int. Please note these additional reports will not feature in the CRIC21 analysis but will be published on the UNCCD website upon submission. There will be no technical support or quality assurance for late submissions.  

It is easy for some to think that water simply comes from the tap, but this limited perspective fails to acknowledge the vital ecosystems from which our water comes. When rivers run dry or become polluted, when groundwater is over-exploited, and when ecosystems are degraded, it is only then that we begin to understand the true value of water.   As we mark World Water Day 2023, we are reminded of the indispensable role water plays in the lives of all living things on our planet. The urgent need for collective action to address the global water and sanitation crisis is reflected in this year's theme, Accelerating Change.   Despite an ambitious commitment to achieve Sustainable Development Goals by 2030, billions of people still lack access to safe water and sanitation. This situation is only going to get worse as we are looking to a hotter, drier future. A future where global demand for freshwater will outstrip supply by 40% by the end of this decade. A future where droughts—driven by climate change but also land degradation—will strike more often and hit even harder.  These problems do not discriminate. They affect countries and regions across all continents, from China to Chad, from Spain to Chile, from Australia to California here in the United States.  Healthy land is critical as we face a future of increasing weather extremes and human pressure. Through sustainable land management we can restore ecosystems, boost drought resilience and safeguard water resources for future generations.   The UN Water Conference that starts today is a once-in-a-generation opportunity to set an ambitious Water Action Agenda. One that can foster a more resilient, equitable, and prosperous future by recognizing the interconnectedness of water, land, climate and nature.  On World Water Day 2023, we reaffirm our steadfast commitment to accelerate change and address the water and sanitation crisis that impacts every aspect of our lives. We call on governments, organizations, businesses, and individuals around the world to join forces, share knowledge, and accelerate change to ensure safe water and sanitation for all.  

尊敬的《联合国防治荒漠化公约》（UNCCD）联络员和相关方， 妇女在维护土地健康方面具有重要作用，然而她们却往往无法控制土地。在世界各地， 妇女面临获得土地权属的重大障碍，因而限制了她们成长和发展的能力。当土地退化和水资源 匮乏时，妇女往往受到的影响最大。 2023 年荒漠化和干旱日的全球焦点是妇女的土地权利——这对于到 2030 年实现性别平等 和土地退化零增长两个相互关联的全球目标以及推进其他可持续发展目标至关重要。 在“她的土地，她的权利”的口号下，今年的荒漠化和干旱日将发出一个强有力的信息，即 投资土地和相关财产的性别平等，是对妇女本身和人类未来的直接投资。 今年的荒漠化和干旱日全球纪念活动将在纽约联合国总部举行，世界各地也将同期举行 纪念活动。我期待通过您的大力支持，让更多的公众和社区了解性别平等在土地可持续未来中 的关键作用。您可以在 2023 年荒漠化和干旱日网页上找到所有联合国语言的公告和背景说 明： https://www.unccd.int/events/desertification-drought-day 此外，诚邀您支持“妇女、女童与土地”运动，该运动旨在宣传妇女为可持续土地管理做出 贡献的成功范例，并动员采取行动加强女性在防治荒漠化、土地退化和干旱方面的领导作用。 访问 https://www.unccd.int/land-and-life/gender/herland 以了解更多信息。 请将您的纪念活动计划发送至 communication@unccd.int，以便我们可以在《联合国防治 荒漠化公约》 (UNCCD) 网站上展示您的活动。进一步的信息将在适当的时候分享。如有任何疑 问，请联系传播、对外关系和伙伴关系的主管森雅.思勘隆女士(Ms. Xenya Scanlon)。 值此荒漠化和干旱日之际，让我们齐心协力，承认并赋予妇女和女童权力，让她们走上全球土地恢复和抗旱工作的前台。

One year into the project, the collaboration between UNCCD, FAO, Aduna, Orgiis and GLOBHE already bears fruit: individual baobab trees can be now recognized from space and a computer system has been trained to plot them on a map. In the Sahel region, where trees play an important role in fixating soils, providing a barrier to land degradation and supporting food security, the baobab is particularly valued, as its fruit not only has a variety of local uses, but can also be a viable commercial export and a source of sustainable income. An icon of the African landscape revered as the tree of life, baobabs cannot be grown on plantations. Proudly standing big and wild, each one is unique and cherished by local communities, as it provides nourishment for people and their animals. Faced with the advance of the climate change, growing energy needs, rapid urbanization and a depleting stock of seedlings that grow to maturity, these green giants need to be carefully monitored and protected. Recent advances in the spatial resolution and availability of satellite imagery have enabled the detection of individual trees from space. Using FAO’s cloud computing platform SEPAL and dense time-series approaches helps identify individual tree species through phenology, or the seasonal foliage pattern, often unique to individual species. The next challenge was pinning down the actual locations of baobab trees and “training” a classification system to extrapolate and predict the tree species associated with each tree canopy. Drone data provided by GLOBHE at a very high spatial resolution allows identification of baobabs, and the  tree locations are then combined with the phenology data to map individual baobabs over vast geographic regions. The resulting maps can be used to inform local communities of the location, number and condition of the baobabs, and enable them “to visualize and analyze high resolution satellite imagery from their mobile phones, allowing to actively monitor and protect this natural resource,” says Yelena Finegold, FAO Forestry Officer. This collaboration between global satellite data providers, drone operators, the private enterprise, the UN and local communities, including women and youth, is a major step toward improving monitoring, conservation and restoration methods in the Sahel. As the project advances toward mapping the baobabs over larger geographical areas, it can also support the implementation of the Great Green Wall Initiative. Better understanding of where to conserve and invest in long-term sustainable use of baobabs can promote value chain development and enable better land management decisions to monitor and safeguard these green powerhouses that provide sustenance, store water and enrich the land. image (c) MakeWaves Media
