AbstractBackgroundMiombo woodlands cover ≈ 2.7 million km2of central and southern Africa between dry (650 mm mean annual rainfall) and moist miombo (1400 mm) and are currently threatened by land use and land cover changes that have intensified over the last 50 years. Despite the miombo’s global significance for carbon (C) storage and sequestration, there has been no regional synthesis that maps carbon stocks and changes in the woodlands. This information is crucial to inform further research for the development of appropriate policies and management strategies to maintain and increase C stocks and sequestration capacity, for conservation and sustainable management. We assembled a systematic map to determine what evidence exists for (1) changes in carbon stocks in miombo woodlands over the period 1960–2015; (2) differences in carbon density in miombo with different conservation status; (3) trends in carbon stock recovery following human disturbance; and (4) fire management impacts on carbon stocks and dynamics.MethodsWe screened 11,565 records from bibliographic databases and grey literature sources following an a priori research protocol. For inclusion, each study had to demonstrate the presence of miombo-typical species (Brachystegia,JulbernardiaandIsoberlinia) and data on above- or below-ground carbon stocks or plant biomass.ResultsA total of 54 articles met the inclusion criteria: 48 quantitative and eight qualitative (two of which included quantitative and qualitative) studies. The majority of studies included in the final analyses are largely quantitative in nature and trace temporal changes in biomass and carbon in the miombo woodlands. Studies reported a wide range (1.3–95.7 Mg ha−1) of above-ground carbon in old-growth miombo woodland. Variation between years and rainfall zones and across conservation area types was large.ConclusionsAn insufficient number of robust studies that met our inclusion criteria from across the miombo region did not allow us to accurately pool carbon stocks and trends in miombo old growth. Thus, we could not address the four questions originally posed in our protocol. We suggest that future studies in miombo woodlands take longer term observational approaches with more systematic, permanent sampling designs, and we identify questions that would further warrant systematic reviews, related to differences in C level recovery after disturbance in fallow and post-clearing re-growth, and the role of controlled fire management.

Keenan; Sango Mahanty; Thilde Bech Bruun; Ole Mertz; Rodel D. Lasco;Les changements économiques mondiaux et les interventions politiques conduisent les transitions des systèmes à marée montante (LFS) vers des utilisations alternatives des terres dans les hautes terres d'Asie du Sud-Est. Cette étude présente un examen systématique de l'impact de ces transitions sur les moyens de subsistance et les services écosystémiques dans la région. Plus de 17 000 études publiées entre 1950 et 2015 ont été réduites, en fonction de leur pertinence et de leur qualité, à 93 études pour une analyse plus approfondie. Notre analyse des transitions de l'utilisation des terres des systèmes de culture alternée à intensifiée a montré plusieurs résultats : plus de ménages avaient augmenté le revenu global, mais ces avantages ont entraîné des coûts importants tels que la réduction des pratiques coutumières, le bien-être socio-économique, les options de subsistance et les rendements de base. L'examen des effets des transitions sur les propriétés du sol a révélé des impacts négatifs sur le carbone organique du sol, la capacité d'échange cationique et le carbone hors sol. Pris ensemble, les facteurs immédiats et sous-jacents de la transition de l'EPA vers des utilisations alternatives des terres, en particulier l'intensification des cultures vivaces et annuelles de rente, ont entraîné une baisse significative de la sécurité préexistante des moyens de subsistance et des services écosystémiques soutenant cette sécurité. Nos résultats suggèrent que les politiques imposant des transitions d'utilisation des terres aux agriculteurs des hautes terres afin d'améliorer les moyens de subsistance et les environnements ont été malavisées ; dans le contexte d'utilisations variées des terres, l'agriculture itinérante peut soutenir les moyens de subsistance et les services écosystémiques qui aideront à amortir les impacts du changement climatique en Asie du Sud-Est. El cambio económico global y las intervenciones políticas están impulsando las transiciones de los sistemas de golondrina larga (EPA) a usos alternativos de la tierra en las tierras altas del sudeste asiático. Este estudio presenta una revisión sistemática de cómo estas transiciones impactan en los medios de vida y los servicios ecosistémicos en la región. Más de 17 000 estudios publicados entre 1950 y 2015 se redujeron, en función de la relevancia y la calidad, a 93 estudios para su posterior análisis. Nuestro análisis de las transiciones del uso de la tierra de los sistemas de cultivo sucios a los intensificados mostró varios resultados: más hogares habían aumentado los ingresos generales, pero estos beneficios tuvieron un costo significativo, como la reducción de las prácticas consuetudinarias, el bienestar socioeconómico, las opciones de medios de vida y los rendimientos de los productos básicos. El examen de los efectos de las transiciones en las propiedades del suelo reveló impactos negativos en el carbono orgánico del suelo, la capacidad de intercambio catiónico y el carbono sobre el suelo. En conjunto, los impulsores inmediatos y subyacentes de las transiciones de la EPA a los usos alternativos de la tierra, especialmente la intensificación de los cultivos comerciales perennes y anuales, condujeron a disminuciones significativas en la seguridad de los medios de vida preexistentes y los servicios ecosistémicos que respaldan esta seguridad. Nuestros resultados sugieren que las políticas que imponen transiciones en el uso de la tierra a los agricultores de las tierras altas para mejorar los medios de vida y los entornos han sido erróneas; en el contexto de los diversos usos de la tierra, la agricultura sucia puede apoyar los medios de vida y los servicios ecosistémicos que ayudarán a amortiguar los impactos del cambio climático en el sudeste asiático. Global economic change and policy interventions are driving transitions from long-fallow swidden (LFS) systems to alternative land uses in Southeast Asia's uplands. This study presents a systematic review of how these transitions impact upon livelihoods and ecosystem services in the region. Over 17 000 studies published between 1950 and 2015 were narrowed, based on relevance and quality, to 93 studies for further analysis. Our analysis of land-use transitions from swidden to intensified cropping systems showed several outcomes: more households had increased overall income, but these benefits came at significant cost such as reductions of customary practice, socio-economic wellbeing, livelihood options, and staple yields. Examining the effects of transitions on soil properties revealed negative impacts on soil organic carbon, cation-exchange capacity, and aboveground carbon. Taken together, the proximate and underlying drivers of the transitions from LFS to alternative land uses, especially intensified perennial and annual cash cropping, led to significant declines in pre-existing livelihood security and the ecosystem services supporting this security. Our results suggest that policies imposing land-use transitions on upland farmers so as to improve livelihoods and environments have been misguided; in the context of varied land uses, swidden agriculture can support livelihoods and ecosystem services that will help buffer the impacts of climate change in Southeast Asia. يقود التغيير الاقتصادي العالمي والتدخلات السياسية التحولات من أنظمة الأرياف الطويلة (LFS) إلى استخدامات بديلة للأراضي في مرتفعات جنوب شرق آسيا. تقدم هذه الدراسة مراجعة منهجية لكيفية تأثير هذه التحولات على سبل العيش وخدمات النظم الإيكولوجية في المنطقة. تم تضييق نطاق أكثر من 17000 دراسة نُشرت بين عامي 1950 و 2015، بناءً على الملاءمة والجودة، إلى 93 دراسة لمزيد من التحليل. أظهر تحليلنا للتحولات في استخدام الأراضي من أنظمة زراعة المحاصيل إلى أنظمة زراعة المحاصيل المكثفة العديد من النتائج: فقد زادت المزيد من الأسر من الدخل الإجمالي، لكن هذه الفوائد جاءت بتكلفة كبيرة مثل الحد من الممارسة العرفية، والرفاهية الاجتماعية والاقتصادية، وخيارات سبل العيش، والمحاصيل الأساسية. كشفت دراسة آثار التحولات على خصائص التربة عن آثار سلبية على الكربون العضوي في التربة، وقدرة تبادل الكاتيون، والكربون فوق الأرض. مجتمعة، أدت الدوافع القريبة والأساسية للانتقال من LFS إلى الاستخدامات البديلة للأراضي، وخاصة المحاصيل النقدية الدائمة والسنوية المكثفة، إلى انخفاض كبير في أمن سبل العيش الموجود مسبقًا وخدمات النظام الإيكولوجي التي تدعم هذا الأمن. تشير نتائجنا إلى أن السياسات التي تفرض تحولات في استخدام الأراضي على مزارعي المرتفعات من أجل تحسين سبل العيش والبيئات قد تم تضليلها ؛ في سياق الاستخدامات المتنوعة للأراضي، يمكن للزراعة العشوائية أن تدعم سبل العيش وخدمات النظم الإيكولوجية التي ستساعد في الحد من آثار تغير المناخ في جنوب شرق آسيا.

AbstractBackgroundIncreasingly, forests are on the international climate change agenda as land use and cover changes drive forest and carbon loss. The ability of forests to store carbon has created programs such as Reducing Emissions from Deforestation and Degradation plus (REDD+), in order to provide incentives for particular land uses and forest management practices. A critical element to REDD+ is the ability to know the carbon-storage potential of an ecosystem, and the factors likely to affect the rate of carbon accumulation or the maximum amount stored. Most REDD+ initiatives have focused on humid tropical forests because of their large stocks per unit area. Less attention has been paid to the carbon-storage potential of tropical dry forests, woodlands and savannas. Although these ecosystems support a lower biomass per unit area, they are more widespread than humid forests. This proposed systematic review examines miombo woodlands, which are the most extensive vegetation formation in Africa and support over 100 million people. We ask: To what extent have changes in land use and land cover influenced above- and below-ground carbon stocks of miombo woodlands since the 1950s?MethodsWe will search systematically for studies that document the influence of land use and cover change on above and below ground carbon in miombo woodlands since the 1950s. We will consult bibliographic databases and an extensive grey literature network, including government reports and forestry offices. Relevant studies will examine the impacts of human activities, fire and other land use or cover changes that affect wood biomass or soil carbon in the miombo region. All included studies will be assessed for the soundness and scientific validity of their study design. A quantitative synthesis will tabulate estimates of various parameters necessary to assess carbon stocks and changes across climate and geological factors; and a qualitative analysis will describe the governing land and forest policies. Understanding the impact that land uses and the associated changes have on carbon storage in the miombo woodlands will contribute to more informed forest management policies and better guided strategies for the United Nations Framework Convention on Climate Change.

AbstractBackgroundMiombo woodlands cover ≈ 2.7 million km2of central and southern Africa between dry (650 mm mean annual rainfall) and moist miombo (1400 mm) and are currently threatened by land use and land cover changes that have intensified over the last 50 years. Despite the miombo’s global significance for carbon (C) storage and sequestration, there has been no regional synthesis that maps carbon stocks and changes in the woodlands. This information is crucial to inform further research for the development of appropriate policies and management strategies to maintain and increase C stocks and sequestration capacity, for conservation and sustainable management. We assembled a systematic map to determine what evidence exists for (1) changes in carbon stocks in miombo woodlands over the period 1960–2015; (2) differences in carbon density in miombo with different conservation status; (3) trends in carbon stock recovery following human disturbance; and (4) fire management impacts on carbon stocks and dynamics.MethodsWe screened 11,565 records from bibliographic databases and grey literature sources following an a priori research protocol.

AbstractBackgroundIncreasingly, forests are on the international climate change agenda as land use and cover changes drive forest and carbon loss. The ability of forests to store carbon has created programs such as Reducing Emissions from Deforestation and Degradation plus (REDD+), in order to provide incentives for particular land uses and forest management practices. A critical element to REDD+ is the ability to know the carbon-storage potential of an ecosystem, and the factors likely to affect the rate of carbon accumulation or the maximum amount stored. Most REDD+ initiatives have focused on humid tropical forests because of their large stocks per unit area. Less attention has been paid to the carbon-storage potential of tropical dry forests, woodlands and savannas. Although these ecosystems support a lower biomass per unit area, they are more widespread than humid forests. This proposed systematic review examines miombo woodlands, which are the most extensive vegetation formation in Africa and support over 100 million people. We ask: To what extent have changes in land use and land cover influenced above- and below-ground carbon stocks of miombo woodlands since the 1950s?MethodsWe will search systematically for studies that document the influence of land use and cover change on above and below ground carbon in miombo woodlands since the 1950s. We will consult bibliographic databases and an extensive grey literature network, including government reports and forestry offices. Relevant studies will examine the impacts of human activities, fire and other land use or cover changes that affect wood biomass or soil carbon in the miombo region. All included studies will be assessed for the soundness and scientific validity of their study design. A quantitative synthesis will tabulate estimates of various parameters necessary to assess carbon stocks and changes across climate and geological factors; and a qualitative analysis will describe the governing land and forest policies. Understanding the impact that land uses and the associated changes have on carbon storage in the miombo woodlands will contribute to more informed forest management policies and better guided strategies for the United Nations Framework Convention on Climate Change.
