Central Asia, which contains extensive dryland ecosystems, is among the regions most heavily impacted by the global climate change, and the trends are projected to accelerate in the coming decades (Lioubimtseva & Henebry, 2009), (Yushanjiang, Zhang, & Leong Tan, 2021), (Schlter, et al., 2013), (Yang, et al., 2019) putting even more pressure on precious natural resources and already fragile ecosystems. https://documents-dds-ny.un.org/doc/UNDOC/LTD/N21/115/89/pdf/N2111589.pdf? Biodiversity is the richness of life in all of its forms, from genes to ecosystems. Biodiversity is a term used to describe the enormous variety of life on Earth. Imperiled species are supposed to be, but that can be tricky depending on what the land is used for. The application of nature-based solutions, such as the large-scale afforestation of the Aral Seabed, potentially creates alternative income sources for the local population. An exosystem is the system of ecological interaction of different environments and can be on land and in water. Photo credit: NASA Earth Observatory, Google Earth. Over half of all the animals already identified are invertebrates. Conservation efforts are necessary to preserve biodiversity and protect endangered species and their habitats. From Borneo to the Andes and pole to pole, Earths plants and animals cling to dwindling habitat and edge closer to extinctiona global biodiversity crisis crying out for action. https://doi.org/10.1016/j.envsci.2019.04.014, Decree of the Cabinet of Ministers of the Republic of Uzbekistan on Additional measures for the creation of forests in the regions and of the green cover in the Aral Sea region. W - low niche diversity and warm water temperatures. Sudochye-Akpetki state wildlife sanctuaryFootnote 6 total area: 2805.07km2, year of designation: 2021. Afforestation measures are discussed as a cost-effective nature-based solution for combatting desertification, adapting to and mitigating climate change impacts through increased carbon sequestration potential (Seddon, et al., 2020) and halting biodiversity loss, as well as improving livelihood opportunities of the local communities (Zhang, Sun, Huettmann, & Liu, 2022), (Di Sacco, et al., 2021), (Djoudi, Brockhaus, & Locatelli, 2013). The issue with low plant survival rates on the dried-out seabed in Uzbekistan is not uncommon: according to Shomurodov et al., (2021), survival rate of plant species in afforested areas is as low as 20%. Glob Change Biol 27:13281348. They're all part of the species biodiversity of this small ecosystem. Private landowners may be reluctant to report them or allow surveys for fear of the restrictions that could follow if they are found. One of the most popular and safe pain relievers,aspirin, was originally made from the bark of willow trees. California is leading the way in tackling some of these challenges. Scientists are interested in how much biodiversity there is on a global scale, given that there is still so much biodiversity to discover. Planning and management of protected areas, their integrity with the landscape, animal migratory routes and areas of anthropogenic activities. The hard work of humansand natures resiliencecan help even the most endangered species climb back from the abyss. Nearly half of the Asian continent is covered by drylands, which contributes to an estimated 34% of the worlds drylands. To complement the systematic review, a non-systematic review was conducted into widely adopted NbS definitions and criteria for the selected ecosystem types. She or he will best know the preferred format. To reach its commitments to increase the percentage of protected areas with respect to the total territory, the government of Uzbekistan almost tripled the area of PAs in Karakalpakstan in 20212022 alone. 2005). The . Climate change. Construction, agriculture, and food and beverages are the largest highly nature-dependent industries, with an economic value roughly twice the size of Germany's economy; China, the EU and the US have the highest absolute economic value in nature-dependent industries A Certified Wildlife Habitat provides food, shelter, water, and a place for native wildlife to raise youngthe essential elements of habitat that wildlife need to survive. Sustain Sci 15:12551266. One of the greatest threats to biodiversity is habitat loss. Right now, about 13 percent of the United States is permanently protected and managed primarily for biodiversity, according to the United States Geological Survey. Artemia, which is used as forage for aquatic species, is currently being harvested and represents business opportunities for the local population (Aladin, et al., 2018), (Arashkevich, Sapozhnikov, Soloviov, Kudyshkin, & Zavialov, 2009). NbS have gained substantial attention in the academic literature recently as a potential approach for simultaneously tackling environmental issues and addressing societal challenges. Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth, like the warm and wet climate of tropical regions.

Alongside multiple obvious benefits of NbS, the literature states also a number of challenges associated with their understanding, implementation, effectiveness, stakeholder participation (Nelson, Bledsoe, Ferreira, & Nibbelink, 2020), lack of standards for their evaluation (Kumar, et al., 2021), (Fernandes & Guiomar, 2018). Tech. Adaptive management, community awareness raising on functions of ecosystems and natural resources in general and their involvement in the planning and implementation processes are highly likely to increase the success of NbS interventions (Belle, Collins, & Jordaan, 2018). Protected areas (PA) that lead to biodiversity conservation and climate mitigation benefits could represent a cost-effective nature-based solution (Mackinnon, Mrema, Richardson, Cooper, & Gidda, 2021), (Roberts, OLeary, & Hawkins, 2020). The most prominent native species in terms of the ability to grow in sandy, loamy and saline soils are reported to be Saxaul (Haloxylon), Salsola Richteri (Moq) Karel ex Litv and Calligonum caput-medusae Schrenk (Bakirov, Khamzaev, & Novitskiy, 2020), Krascheninnikovia eversmanniana and Artemisia ferganensis (Shomurodov, et al., 2021).

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. All of these threats have put a serious strain on the diversity of species on Earth. Land Degrad Dev 27:18311839. As large-scale afforestation of the former Aral seabed is planned to continue through 2030, as stipulated by the Decree of the Cabinet of Ministers of the Republic of UzbekistanFootnote 2, there is at the very least a need for planning and monitoring, as well as selection of native species to ensure afforestation success.

Summary: Amazonia represents the quintessence of biodiversity - the richest ecosystem on earth. https://doi.org/10.1007/s00267-023-01822-z, DOI: https://doi.org/10.1007/s00267-023-01822-z. The systematic search on NbS implementation in dryland ecosystems resulted in 2557 non-duplicative scientific publications, 2451 of which were filtered out as being irrelevant (see Appendix 1 for detailed information). An exosystem is the system of ecological interaction of different environments and can be on land and in water. Nonetheless, wetlands in the Aral Sea basin serve as an important habitat both for inland waterbirds and for the migratory species in Central Asia (Kasprzykowski, Goawski, Mitrus, & Staski, 2014). Hence, water availability needs to be considered thoroughly when it comes to planning desert greening activities, as there is large-scale evidence of failed or low effective interventions aimed at greening the Aral Seabed.

Biodiversity is extremely important to people and the health of ecosystems. The chart shows information about four ecosystems. (A biological community is an interacting group of various species in a common location.) Encyclopedia of Earth: Biodiversity Oxford University Press, New York: 2000 Further, wetlands nested within larger dryland landscapes are reported to be among the ecosystems most effected by climate change (Parra, et al., 2021), (Williams, 1999), hence are in need of urgent conservation action. As reported by Li et al. Extinction is a natural part of life on Earth. This means that millions of other organisms remain a complete mystery.

Antarctica, covered almost entirely by an ice sheet, has low biodiversity. Warmer ocean temperatures damagefragileecosystems such as coral reefs. Nature-based solutions, as a recently emerged approach for sustainably mitigating and adapting to environmental challenges, have gained considerable attention in the scientific literature recently. NbS can often incorporate traditional knowledge, and should ideally involve a wide range of stakeholders - in particular, local communities. Currently we have identified only 1.7 million species, so we have a long way to go before we can come close to figuring out exactly how many species are on Earth.
