Abstract Many agricultural regions in China are likely to become appreciably wetter or drier as the global climate warming increases. However, impact of these change patterns on intensity soil greenhouse gas (GHG) emissions (GHGI, GHG per unit crop yield) has not yet been rigorously assessed. By integrating an improved ecosystem model and a meta‐analysis multiple field studies, we found that is expected cause 20.0% yield loss, while stimulating by 12.2% between 2061 2090 China's regions. A wetter‐warmer (WW) would adversely equal basis lead 1.8‐fold‐ increase relative those drier‐warmer (DW) climate. Without water limitation/excess, extreme heat (an more than 1.5°C average temperature) during growing season amplify 15.7% simultaneously elevating 42.5% compared below 1.5°C. when coupled with drought, it aggravate loss 61.8% without reducing corresponding emissions. Furthermore, emission WW 22.6% DW Under this intense climate, use nitrogen fertilizer 37.9% necessarily gaining advantage These findings suggest threat world efforts reduce may be great even greater world.

Soils provide key ecosystem services and are crucial to combat climate change. Agriculture provides important but also causes negative environmental effects depending on agricultural management. In this regard, crop diversification is a promising sustainable land management strategy soil erosion degradation, mitigate change ensure food security. Here, we assess the combined short-term of no tillage several physico-chemical parameters related functioning as well yields in rainfed almond (Prunus dulcis Mill.) orchard under semiarid Mediterranean conditions. Almond trees were inter-cropped with Capparis spinosa L. (caper) or Thymus hyemalis Lange (winter thyme) compared monocrop system. The experimental design consisted three plots randomized-block design, replicates for each treatment (almond monocrop, caper, winter thyme).

Abstract U.S. rice paddies, critical for food security, are increasingly contributing to non‐CO 2 greenhouse gas (GHG) emissions like methane (CH 4 ) and nitrous oxide (N O). Yet, the full assessment of GHG balance, considering trade‐offs between soil organic carbon (SOC) change emissions, is lacking. Integrating an improved agroecosystem model with a meta‐analysis multiple field studies, we found that paddies were rapidly growing net emission sources, increased 138% from 3.7 ± 1.2 Tg CO eq yr −1 in 1960s 8.9 2.7 2010s.

Grassland ecosystems store significant amounts of organic carbon (C) and have the potential to function as a source or sink greenhouse gases (GHGs) under different environmental conditions management practices. However, effects (clipping frequency N fertilisation) on GHGs remain uncertain. In this study, field-based experiment with automated-lid gas exchange chambers was conducted simultaneously measure GHG fluxes (CO2, N2O, CH4), their overall global warming (GWP-100) impact, net ecosystem (NEE) from grassland. The had two clipping frequencies (simulating moderate high grazing intensity) nitrogen (N) fertiliser treatments (0 40 kg ha−1 year−1). measurements were during periods (each approximately 2 weeks long) varied temperature moisture in early autumn. High caused higher daily NEE emissions, GWP-100 impact lower photosynthesis; however, it did not significantly affect these parameters. Nitrogen fertilisation than treatment, but N2O likely be dependent time application. Methane (CH4) predominantly controlled by soil moisture, whereas nitrous oxide (N2O) more strongly affected temperature. emissions increased after break-point 20°C. Our results highlighted sensitivity CH4 uptake conditions, particularly increase warmer temperatures. main contributor study CO2 uptake. For observation period, grassland small C sink. comprehensive understanding, longer-term studies spanning over several years are needed accurately assess practices emissions.
