Terrestrial nature-based climate solutions (NbCS) for carbon dioxide removal (CDR) are critical mitigating change. However, the arid climates characteristic of drylands (aridity index <0.65) often limit effectiveness many NbCS. At same time, cover approximately 45% global land area and threatened by soil degradation, necessitating deployment CDR methods that also promote health. Soil amendments with high CO 2 sorption capacity, such as biochar, could provide potential health benefits in provided they do not negatively impact large inorganic pools typical dryland soils. The dynamics therefore assessing response systems to sorbing amendments. To assess sorption, we developed a 1D reactive transport model unsaturated soils equilibrium dissolved calcite under varying respiration rates amendment application conditions. simulations highlight how alteration due biochar affects carbon, pH, Ca 2+ , calcite. transient conditions emerge, including delayed emissions respired emphasize need consider times monitoring campaigns based on measurements. In scenarios where is low, drylands, becomes increasingly important. Although variable was modest relative overall deployment, impacts altered gas important developed.

Global estimates of the size, distribution, and vulnerability soil inorganic carbon (SIC) remain largely unquantified. By compiling 223,593 field-based measurements developing machine-learning models, we report that global soils store 2305 ± 636 (±1 SD) billion tonnes as SIC over top 2-meter depth. Under future scenarios, acidification associated with nitrogen additions to terrestrial ecosystems will reduce (0.3 meters) up 23 next 30 years, India China being most affected. Our synthesis present-day land-water inventories inland-water carbonate chemistry reveals at least 1.13 0.33 is lost inland-waters through annually, resulting in large but overlooked impacts on atmospheric hydrospheric dynamics.

Abstract Drylands, comprising semi‐arid, arid, and hyperarid regions, cover approximately 41% of the Earth's land surface have expanded considerably in recent decades. Even under more optimistic scenarios, such as limiting global temperature rise to 1.5°C by 2100, semi‐arid lands may increase up 38%. This study provides an overview state‐of‐the‐art regarding changing aridity arid with a specific focus on its effects accumulation availability carbon (C), nitrogen (N), phosphorus (P) plant–soil systems. Additionally, we summarized impacts rising biodiversity, service provisioning, feedback climate change across scales.

Abstract Drylands are important carbon pools and highly vulnerable to climate change, particularly in the context of increasing aridity. However, there has been limited research on effects aridification soil total including organic inorganic carbon, which hinders comprehensive understanding projection dynamics drylands. To determine response aridification, understand how drives variation along aridity gradient through different ecosystem attributes, we measured across a ~4000 km drylands northern China. Distribution patterns at sites were analyzed. Results showed that had complementary relationship, is, an increase positively compensated for decrease semiarid hyperarid regions. Soil exhibited nonlinear change with aridity, effect shifted from negative positive level 0.71. In less arid regions, leads mainly whereas more promotes thus carbon. Our study highlights importance needs be considered when developing measures conserve terrestrial sink.
