New (a)biotic conditions resulting from climate change are expected to change disturbance dynamics, such as windthrow, forest fires, droughts, and insect outbreaks, and their interactions. These unprecedented natural disturbance dynamics might alter the capability of forest ecosystems to buffer atmospheric CO2 increases, potentially leading forests to transform from sinks into sources of CO2. This study aims to enhance the ORCHIDEE land surface model to study the impacts of climate change on the dynamics of the bark beetle, Ips typographus, and subsequent effects on forest functioning. The Ips typographus outbreak model is inspired by previous work from Temperli et al.\u00a0(2013) for the LandClim landscape model. The new implementation of this model in ORCHIDEE r8627 accounts for key differences between ORCHIDEE and LandClim: (1)\u00a0the coarser spatial resolution of ORCHIDEE; (2)\u00a0the higher temporal resolution of ORCHIDEE; and (3)\u00a0the pre-existing process representation of windthrow, drought, and forest structure in ORCHIDEE. Simulation experiments demonstrated the capability of ORCHIDEE to simulate a variety of post-disturbance forest dynamics observed in empirical studies. Through an array of simulation experiments across various climatic conditions and windthrow intensities, the model was tested for its sensitivity to climate, initial disturbance, and selected parameter values. The results of these tests indicated that with a single set of parameters, ORCHIDEE outputs spanned the range of observed dynamics. Additional tests highlighted the substantial impact of incorporating Ips typographus outbreaks on carbon dynamics. Notably, the study revealed that modeling abrupt mortality events as opposed to a continuous mortality framework provides new insights into the short-term carbon sequestration potential of forests under disturbance regimes by showing that the continuous mortality framework tends to overestimate the carbon sink capacity of forests in the 20- to 50-year range in ecosystems under high disturbance pressure compared to scenarios with abrupt mortality events. This model enhancement underscores the critical need to include disturbance dynamics in land surface models to refine predictions of forest carbon dynamics in a changing climate.</p></article>", "keywords": ["cycle du carbone", "[SDE] Environmental Sciences", "http://aims.fao.org/aos/agrovoc/c_24242", "P40 - M\u00e9t\u00e9orologie et climatologie", "mod\u00e8le de simulation", "Ips typographus", "http://aims.fao.org/aos/agrovoc/c_16411", "http://aims.fao.org/aos/agrovoc/c_2391", "http://aims.fao.org/aos/agrovoc/c_1666", "K70 - D\u00e9g\u00e2ts caus\u00e9s aux for\u00eats et leur protection", "http://aims.fao.org/aos/agrovoc/c_6111", "http://aims.fao.org/aos/agrovoc/c_4549f84e", "perturbation de l'\u00e9cosyst\u00e8me", "surveillance \u00e9pid\u00e9miologique", "mod\u00e9lisation", "s\u00e9cheresse", "changement climatique", "QE1-996.5", "http://aims.fao.org/aos/agrovoc/c_230ab86c", "U10 - Informatique", " math\u00e9matiques et statistiques", "Geology", "H10 - Ravageurs des plantes", "http://aims.fao.org/aos/agrovoc/c_331583", "s\u00e9questration du carbone", "dynamique des populations", "[SDE]Environmental Sciences", "http://aims.fao.org/aos/agrovoc/c_30153", "http://aims.fao.org/aos/agrovoc/c_17299"]}, "links": [{"href": "https://doi.org/20.500.11850/706699"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Geoscientific%20Model%20Development", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "20.500.11850/706699", "name": "item", "description": "20.500.11850/706699", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/20.500.11850/706699"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2024-11-11T00:00:00Z"}}, {"id": "20.500.12123/10635", "type": "Feature", "geometry": null, "properties": {"updated": "2026-09-21T16:22:38Z", "type": "Journal Article", "created": "2021-05-18", "title": "Landholders' perceptions on legal reserves and agricultural intensification: Diversity and implications for forest conservation in the eastern Brazilian Amazon", "description": "Open AccessLa protecci\u00f3n de los bosques en tierras de propiedad privada es una piedra angular del marco de la pol\u00edtica ambiental brasile\u00f1a. La legislaci\u00f3n brasile\u00f1a exige que todas las fincas del pa\u00eds mantengan y protejan las \u00e1reas forestales conocidas como Reservas Legales. Dado que las Reservas Legales tienen importantes implicaciones para la protecci\u00f3n de los bosques y la producci\u00f3n agr\u00edcola, es clave que entendamos las percepciones de los propietarios de tierras hacia las Reservas Legales. Aplicamos la metodolog\u00eda Q para identificar diferentes perspectivas de los propietarios medianos y grandes sobre las Reservas Legales y su relaci\u00f3n con la intensificaci\u00f3n agr\u00edcola en el municipio de Paragominas, en la Amazon\u00eda oriental. Realizamos 31 entrevistas en las que los propietarios ordenaron 36 declaraciones en una matriz de distribuci\u00f3n casi normal. Se identificaron tres grupos de propietarios de tierras: 1) los entusiastas de la planificaci\u00f3n del uso de la tierra (n = 16) estaban interesados en iniciativas de zonificaci\u00f3n para explorar dise\u00f1os de paisajes alternativos y legislaci\u00f3n que puedan ofrecer mejores resultados de conservaci\u00f3n y producci\u00f3n; 2) los partidarios de la agricultura basada en agroqu\u00edmicos (n = 7) ten\u00edan los puntos de vista m\u00e1s cr\u00edticos contra las Reservas Legales y percib\u00edan sus costos como m\u00e1s altos que los posibles beneficios ambientales y de calidad de vida; 3) los respondedores del mercado complacientes con las pol\u00edticas (n = 4) no mostraron inter\u00e9s en las reformas de las Reservas Legales y fueron el grupo m\u00e1s impulsado por el mercado. Si bien Paragominas ha logrado \u00e9xitos notables en detener la deforestaci\u00f3n a gran escala a trav\u00e9s de un pacto social de 'Municipio Verde', abordar la persistente degradaci\u00f3n y fragmentaci\u00f3n de los bosques en la regi\u00f3n sigue siendo una prioridad clave. Las iniciativas de gobernanza local que tienen en cuenta las percepciones de m\u00faltiples partes interesadas sobre la protecci\u00f3n de los bosques pueden fomentar el di\u00e1logo y el entendimiento mutuo para conservar y restaurar eficazmente las Reservas Legales. Los conocimientos sobre las percepciones de los grandes terratenientes sobre las Reservas Legales pueden informar dichos procesos de gobernanza para conciliar la protecci\u00f3n forestal y la intensificaci\u00f3n agr\u00edcola sostenible en Paragominas.", "keywords": ["Amazonas (Brasil)", "Economics", "FOS: Political science", "SAO-FELIX", "http://aims.fao.org/aos/agrovoc/c_16141", "Social Sciences", "NEEDS", "01 natural sciences", "Agricultural and Biological Sciences", "Reservas Forestales", "Natural resource economics", "conservation des for\u00eats", "FRONTIER", "K01 - Foresterie - Consid\u00e9rations g\u00e9n\u00e9rales", "Stakeholder", "11.
