“…Last but not least, agroforestry also impacts microclimatic conditions in agricultural landscapes. Trees provide shade and act as windbreaks, which can reduce evaporation rates and moderate temperatures [40]. This can be particularly beneficial in regions that are experiencing higher temperatures and increased evaporation due to climate change.…”

Agroforestry, as the synergistic integration of woody perennials with crops and livestock systems, is posited along with a multi-functional land-use strategy with substantial implications for climate adaptation and mitigation. The article embarks on an analytical journey through historical paradigms, typologies such as silvo-pastoral and agro-silvicultural systems, and evaluates their contributions to enhancing soil health, water management, carbon sequestration, biodiversity, and microclimate regulation. Distinctive case studies spanning diverse geographic regions including Africa, Southeast Asia, Europe and South America are scrutinized to elucidate how agroforestry initiatives can be contextually optimized for addressing region-specific environmental challenges and socio-economic needs. Sustainability aspects are dissected into economic, social, and environmental benefits, thereby constructing a holistic view of the multi-dimensional advantages of agroforestry systems. The review identifies significant research lacunae, anticipates technological innovations such as remote sensing and machine learning algorithms for data-driven management, and delineates strategies for scaling up best practices. Additionally, the article explores the impediments to widespread adoption, which encompass land tenure complications, economic viability, socio-cultural factors, and policy and regulatory constraints. In the review accentuates the need for an integrated, multi-disciplinary approach involving concerted efforts from researchers, policymakers, and stakeholders for the actualization of agroforestry's full potential in achieving global sustainability and climate resilience objectives.

“…Land conversion to silvopasture increases C accumulation compared to pure pastures or rangeland [53,56] . For example, silvopasture (69.2 Mg C ha -1 ) contained 1.12 and 1.69 times more soil C in the 0-30 cm soil than sown pasture (62 Mg C ha -1 ) and native rangeland (40.9 Mg C ha -1 ) 22 years after the conversion from native rangeland to silvopasture or sown pasture [53] .…”

Climate change is a major global threat affecting food security and sustainability. Land use systems involving trees have the potential to positively impact climate change by reducing atmospheric carbon dioxide (CO2) and providing long-term carbon (C) storage. This review evaluated the C sequestration potential of two major land use systems of the United States (US) involving trees, forests and agroforests, which can also provide other ecosystem services.The estimated total forest C stock on forest land in the US in 1990 was 50,913 Tg and another 1885 Tg remained in harvested wood and discarded wood products. From 1990 to 1995, total C stock rose by 2%, and from 2000 to 2005, it rose by 1.7%. The US forests collectively lose (flux) about 200 Mg C y-1 from disturbance and harvesting. Currently, about 12% of the conterminous US forest land is at high or very high risk of wildfire. Annually, insects and diseases could transfer ~ 21 Tg of live aboveground biomass to litter and woody debris pools. A scenario that targets an afforestation policy for rural landowners in the eastern US and a reforestation policy targeting understocked federal forest lands in the western would improve US annual sequestration compared to the baseline of 323 Tg CO2 eq yr-1 in 2015 to 469 Tg CO2 eq yr-1 in 2050.Agroforestry offers greater potential to increase C sequestration of predominantly agriculture-dominated landscapes than monocrop agriculture by storing C in above- and belowground biomass, soil, and living and dead organisms and further extending the duration of C in soils. The estimated total C sequestration of current alley cropping (211,938 ha), riparian buffers (640,732 ha), silvopasture (34 Mha), and windbreak (2.37 Mha) practices is 219 Tg C yr-1. The total C sequestration would be 240 Tg C yr-1 with 5% of the US cropland converted to alley cropping (3.7 Tg yr-1), 15-m wide riparian buffers on both sides of 5% of the total stream length (4.75 Tg yr-1), 34 Mha converted to silvopasture (207 Tg yr-1), and windbreaks on 5% (7.45 Mha) of the cropland (25 Tg yr-1). Despite many limitations including uncertainty of land areas under agroforestry, lack of standardized estimation protocols, and lack of accountability on various C stocks (source-sink services, detritus C, insect/pest damages, etc.), we believe these new accrual rates and the land areas under each practice are much more realistic as new information became available over the last decade.The total C sequestration by forests (776) and agroforests (219) is 995 Tg yr-1 and represents approximately 15% of the US CO2 emissions. This review highlights the importance of sustainable management of forests and integration of agroforestry on agricultural lands to mitigate climate challenges further while meeting society’s need for food and a healthy environment.
