Land-surface characteristics and climate in West Africa: Models' biases and impacts of historical anthropogenically-induced deforestation
Land Use Land-Cover Change (LULCC), such as deforestation, affects the climate system and land-atmosphere interactions. Using simulations carried out within the LUCID (Land Use and Climate, IDentification of robust Impacts) project framework, we first quantify the role of historical land-cover chang...

Using simulations carried out within the LUCID (Land Use and Climate, IDentification of robust Impacts) project framework, we first quantify the role of historical land-cover change induced by human activities on surface climate in West Africa. Focusing on two contrasted African regions, we find that climate responses of land-use changes are small but they are still statistically significant. In Western Sahel, a statistically significant near-surface atmospheric cooling and a decrease in water recycling are simulated in summer in response to LULCC. Over the Guinean zone, models simulate a significant decrease in precipitation and water recycling in autumn in response to LULCC. This signal is comparable in magnitude with the effect induced by the increase in greenhouse gases. Simulated climate changes due to historical LULCC could however be underestimated because: (i) the prescribed LULCC can be underestimated in those regions; (ii) the climate models underestimate the coupling strength between West African surface climate and leaf area index (LAI) and (iii) the lack of interactive LAI in some models. Finally, our study reveals indirect atmospheric processes triggered by LULCC. Over the Western Sahel, models reveal that a significant decrease in solar reflection tend to cool down the surface and thus counteract the atmospheric feedback. Conversely, over the Guinea zone, models reveal that the indirect atmospheric processes and turbulent heat fluxes dominate the climatic responses over the direct effects of LULCC.application/pdfhttps://doi.org/10.3390/su9101917ISSN: 2071-1050https://repository.urosario.edu.co/handle/10336/28029engSociety for Urban EcologyNo. 10Sustainability, Sustainability (Switzerland)Vol. 9Sustainability, Sustainability, ISSN: 2071-1050, Vol.9, No.10 (2017)https://www.mdpi.com/2071-1050/9/10/1917Abierto (Texto Completo)http://purl.org/coar/access_right/c_abf2Sustainability, Sustainability (Switzerland)instname:Universidad del Rosarioreponame:Repositorio Institucional EdocURClimate changeDeforestationLand use-land cover changeLand-atmosphere interactionLand surface modelsLand-surface characteristics and climate in West Africa: Models' biases and impacts of historical anthropogenically-induced deforestationCaracterísticas de la superficie terrestre y clima en África occidental: sesgos e impactos de los modelos de la deforestación histórica inducida antropogénicamentearticleArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501Souleymane, SDe Noblet-Ducoudré, NathalieQuesad, BenjaminIbrahima, SMoctar Dieye, AmadouThierno Gaye, AmadouSultan, BenjaminORIGINALsustainability-09-01917-v2.pdfapplication/pdf10096578https://repository.urosario.edu.co/bitstreams/68e9f846-695b-47e0-b4ff-df222b148789/downloadb203ac9956a6e302026a373554eed602MD51TEXTsustainability-09-01917-v2.pdf.txtsustainability-09-01917-v2.pdf.txtExtracted texttext/plain79032https://repository.urosario.edu.co/bitstreams/f9c01a61-23b3-462f-b6c8-6babae958a1e/downloadd6f0882ee42759cfe3a0b60165ba5299MD52THUMBNAILsustainability-09-01917-v2.pdf.jpgsustainability-09-01917-v2.pdf.jpgGenerated Thumbnailimage/jpeg4706https://repository.urosario.edu.co/bitstreams/14c7e4c0-c456-4e40-8688-9b3e1b085b1a/download654c7eb78a786e32d0e38d0388cc311fMD5310336/28029oai:repository.urosario.edu.co:10336/280292022-05-02 07:37:21.953429https://repository.urosario.edu.coRepositorio institucional EdocURedocur@urosario.edu.co |

Land Use Land-Cover Change (LULCC), such as deforestation, affects the climate system and land-atmosphere interactions. Using simulations carried out within the LUCID (Land Use and Climate, IDentification of robust Impacts) project framework, we first quantify the role of historical land-cover change induced by human activities on surface climate in West Africa. Focusing on two contrasted African regions, we find that climate responses of land-use changes are small but they are still statistically significant. In Western Sahel, a statistically significant near-surface atmospheric cooling and a decrease in water recycling are simulated in summer in response to LULCC. Over the Guinean zone, models simulate a significant decrease in precipitation and water recycling in autumn in response to LULCC. This signal is comparable in magnitude with the effect induced by the increase in greenhouse gases. Simulated climate changes due to historical LULCC could however be underestimated because: (i) the prescribed LULCC can be underestimated in those regions; (ii) the climate models underestimate the coupling strength between West African surface climate and leaf area index (LAI) and (iii) the lack of interactive LAI in some models. Finally, our study reveals indirect atmospheric processes triggered by LULCC. Over the Western Sahel, models reveal that a significant decrease in solar reflection tend to cool down the surface and thus counteract the atmospheric feedback. Conversely, over the Guinea zone, models reveal that the indirect atmospheric processes and turbulent heat fluxes dominate the climatic responses over the direct effects of LULCC. |
