<p>Global warming is leading to increased temperatures, accentuated evaporation of terrestrial water and the atmosphere moisture content, resulting in frequent droughts heavy precipitation events. It necessary assess sensitivity soil organic carbon (SOC) under storing practices response increasing moisture, temperature dry-wet cycles order anticipate future losses. We evaluated impact these climatic events through an incubation experiment on temperate luvisols from conservation agriculture, waste products applications, i.e. biowaste, residual municipal solid farmyard manure composts compared with conventionally managemed soils. The alternative management options all have led SOC stocks. Soil samples were incubated lab different temperatures (20, 28 35°C), conditions (pF1.5; 2.5 4.2) dry(pF4.2)-wet (pF1.5) cycles. Dry-wet caused CO2 flushes but overall did not stimulate mineralization relative wet controls (pF1.5 pF2.5). Overall additional stored was more sensitive climate change (temperature, cycles) than existing SOC.</p>

Abstract Agroforestry can offer carbon sequestration, higher system productivity and biodiversity. However, a limited number of field experiments exist to study their feasibility trade-offs for large scale deployment. Agroecosystem models could represent valuable tool ex ante assessment. Here, we present ZonalCent, novel approach use the DayCent model simulate multi-component agroforestry systems by splitting them into several independent zones, simulating each zone individually. We used six sites in France evaluate how well ZonalCent represented sequestration tree biomass, soil organic stocks total system. This proved promising because with default parameter set DayCent, was highly suitable (Nash–Sutcliffe modelling efficiency; NSE 0.86), potential (NSE 0.55), despite tendency overestimate SOC 0.38). Only one site had yield data there, approximate mean reduction—yet more detailed evaluation is necessary. Negative correlations showed that simulated most strongly affected (a) shading mature trees (b) loss arable area due grass strips. While may be needed process understanding, includes important interactions (light, water, nutrients, temperature) simple but effective way readily used—because it based on DayCent—to estimate at larger scales.

Green technology innovation (GTI) is one of the most important factors influencing agricultural carbon emission intensity (ACEI). Various studies have explored impact GTI on ACEI, but path mechanism has not been fully explained. This study incorporates and ACEI into constant elasticity substitution (CES) production function constructs a theoretical model to analyse their direct mechanisms. Drawing effect theory Marshall–Arrow–Romer (MAR) externalities theory, this introduces two regulatory mechanisms: optimization energy structure industry agglomeration (AIG). Additionally, it explores pathway mechanisms under influence spatial spillover effects based Tobler's first law geography. Then, taking Jiangsu Province in China as case study, empirical tests are conducted using LSDVC dynamic SAR models. The results follows. (1) effectively inhibits directly, significantly positive reduction short long terms. (2) Energy positively regulates reduction, nearby cities may help restrain local city term. (3) AIG regulating reducing moderating (4) When both pathways employed simultaneously, or neighbouring areas expected become ineffective. These findings useful for solving problem by managing transfer distribution between different regions, considering effects.

Abstract Current soil‐ and land degradation seriously challenge our societies; it contributes to climate change, loss of biodiversity agricultural productions. Yet, soils are also seen as a major part the solution, if maintained or restored provide ecosystem services. Climate‐smart sustainable management can options for soil health maintenance restoration. In European Union, resource sustainability addressed in Green Deal that, among other goals, aspires towards healthy climate‐resilient sector that will produce sufficient products without damaging ecosystems contribute better mitigate change. The Joint Programme (EJP) SOIL was set up these goals by developing knowledge, tools an integrated research community foster climate‐smart provides diversity service, such adapting mitigating allowing food production, sustaining biodiversity.

Afforestation of degraded areas was suggested as CO2 sink, contributing to climate change mitigation. Yet, few studies have assessed this sink by combining measurements on carbon (C) in the biomass and soil, despite it being crucial properly estimate mitigation potential. Here, we combined C stocks afforestation plots different ages former cropland a Cambisol landscape Extremadura, Spain. The were afforested with two native tree species (Quercus ilex L.
