The availability of nitrogen(N)is crucial for both the productivity of terrestrial and aquatic ecosystems ***,the overuse of artificial fertilizers and the energy required to fix nitrogen have pushed the global nitrogen cycle(N-cycle)past its safe operating limits,leading to severe nitrogen pollution and the production of significant amounts of greenhouse gas nitrous oxide(N2O).The anaerobic ammonium oxidation(anammox)mechanism can counteract the release of ammonium and N2O in many oxygenlimited situations,assisting in the restoration of the homeostasis of the Earth’s N *** this work,we looked into the characteristics of the anammox hotspots’distribution across various types of ecosystems *** hotspots are present at diverse oxic-anoxic interfaces in terrestrial systems,and they are most prevalent at the oxic-anoxic transition zone in aquatic *** on the discovery of an anammox hotspot capable of oxidizing ammonium anoxically into N2 without N2O by-product,we then designed an innovative concept and technical routes of nature-based anammox hotspot geoengineering for climate change,biodiversity loss,and efficient utilization of water *** 15 years of actual use,anammox hotspot geoengineering has proven to be effective in ensuring clean drinking water,regulating the climate,fostering plant and animal diversity,and enhancing longterm environmental *** sustainable biogeoengineering of anammox could be a workable natural remedy to resolve the conflicts between environmental pollution and food security connected to N management.

Paddy fields play an important role in global carbon(C) cycling and are an important source of methane(CH_(4)) emissions. Insights into the processes influencing the dynamics of soil organic C(SOC) in paddy fields are essential for maintaining global soil C stocks and mitigating climate change. Periphytic biofilms composed of microalgae, bacteria, and other microorganisms are ubiquitous in paddy fields, where they directly mediate the transfer of elements at the soil-water interface. However, their contributions to C turnover and exchange have been largely neglected. Periphytic biofilms affect and participate in soil C dynamics by altering both abiotic(e.g., pH and redox potential) and biotic conditions(e.g., microbial community composition and metabolism). This review summarizes the contributions of periphytic biofilms to soil C cycling processes, including carbon dioxide fixation, SOC mineralization, and CH_(4) emissions. Future research should be focused on: i) the mechanisms underlying periphytic biofilm-induced C fixation and turnover and ii) quantifying the contributions of periphytic biofilms to soil C uptake, stabilization, and sequestration in paddy fields.

The Tibetan Plateau, also known as the Water Tower of Asia, is home to 1424 lakes with areas of greater than 1 km2, and supplies freshwater resources for more than 1.4 billion people [1,2]. In the context of recent global change, the warmer climate has caused prominent changes in the characteristics of the lake evolution on the Tibetan Plateau, such as changes in the hydrology.

Climate conditions have long been acknowledged as a pivotal factor shaping regional productivity and influencing available resources,consequently playing an important role in driving social changes throughout human history [1-3].In ancient East Asia,the Chinese agrarian civilization emerged around 4000 years ago in northern China,the region termed the"Central Plains".This region faced recurrent episodes of large-scale social unrest,profoundly impacting the societal structure and dynastic cycles [4].These episodes were marked by extended civil peasant uprisings and/or incursions from northern nomadic tribes,often spanning decades to centuries [5].Both the agrarian societies in the Central Plains and the husbandry-based nomadic tribes in the vast northern grasslands,characterized by semi-arid and semi-humid climates,were notably sensitive to climate variations [6].

Dams and reservoirs play an essential role in regulating and managing water *** the middle of the 20th century,the growing demand for water and hydropower has led to an unprecedented boom in reservoir construction worldwide[1,2].Meanwhile,reservoir construction has also resulted in a variety of ecological and socioeconomic impacts[3–5].Reservoirs transform natural flow regimes into conditions favored by human *** associated flow regulations,especially in reservoirs constructed in recent decades(e.g.,after 2000)with greater seasonal variability[6,7],represent a strong human-induced alteration of the hydrologic *** reservoir construction continues to boom in many parts of the world,an up-to-date and openaccess inventory of reservoirs worldwide remains critically desired.
