There was a 45% reduction in SOC in coffee growing systems and a 75% reduction in MB-C in CCM compared to NF.

The objective of this study was to quantify soil organic carbon (SOC) concentrations and stocks under tree buffer (TB), grass buffer (GB), grass waterways (WW) and crop field (CS, corn-soybean rotation) to evaluate the significance of conservation measures in C sequestration projects. Soil samples were collected up to 1 m depth at upper, middle, and lower landscape positions from 26-year-old TB, GB, and WW in a watershed. The SOC concentration decreased with increasing soil depth for all four land uses. However, as expected, bulk density increased with increasing soil depth for all four land uses. It was highest for the CS land use. In 2023, for the depth of 0–10 cm, SOC increased by +0.63, +1.06, +1.37 and +1.63% in CS, GB, TB, and WW, respectively, since the land uses were established 26 years ago. Land uses had greater impacts on SOC stock in the top 50 cm depth, with WW (113.5 ± 12.9 Mg ha<sup>−1</sup>), TB (106 ± 14.5 Mg ha<sup>−1</sup>), and GB (102.4 ± 11.6 Mg ha<sup>−1</sup>) compared to CS (90.9 ± 10.2 Mg ha<sup>−1</sup>).

Our robust models (AUC of 0.7–0.9) indicate temperature-related variables as relevant for Arabica coffee suitability, while precipitation-related variables determine Robusta coffee and banana suitability. Under current climatic conditions, only a quarter of the total land area is suitable for growing Arabica coffee, while over three-quarters are suitable for Robusta coffee and bananas. Our results suggest that climate change will reduce the area suitable to grow Arabica coffee, Robusta coffee and bananas by 20%, 9% and 3.5%, respectively, under SSP3-RCP7.0 by 2050. A shift in areas suitable for Arabica coffee to highlands might occur, leading to potential encroachment on protected areas. In our model, implementing agroforestry with up to 50% shading could partially offset suitable area losses for Robusta coffee—but not for Arabica coffee. The potential to produce valuable Arabica coffee thus decreases under climate change and cannot be averted by agroforestry. We conclude that the implementation and design of agroforestry must be based on species, elevation, and regional climate projections to avoid maladaptation.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 6","pages":"1555 - 1577"},"PeriodicalIF":2.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-024-01025-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141517956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
