“…This intentional arrangement of the different components leads to both ecological and economic interactions that can provide diversified products which otherwise can't be achieved in the sole cropping system. Globally, agroforestry is practices by more than 1.2 billion people, spanning over 1 billion hectares of land [6], helping different nations to achieve atleast nine of the United Nation's Sustainable Development Goals (SDGs) (Figure 1). However, there are several agroforestry practices which can be classified into agri-silivicultural (agriculture crops and trees), silvopastoral (trees, grasses and livestock), agrosilvopastoral systems (agriculture crops, trees, grasses and livestock) and other specific systems (aqua-forestry, apiculture with trees) [7].…”

The current world faces several challenges, including climate change, an exponentially increasing population, the loss of biodiversity and environmental concerns which necessities the adoption of the sustainable nature-based solutions such as agroforestry. Agroforestry is the intricate integration of trees, crops, and livestock on the same piece of land management unit that helps to restore the ecosystem, improve soil health, thus combating the environmental degradation. Moreover, agroforestry has also emerged as a potential tool that bridges the ecological preservation, while increasing or at least maintaining the productivity of the whole agroecosystem. Agroforestry is a contemporary food system that relies primarily on natural inputs, leading to the creation of more sustainable and resilient landscapes. Simultaneously, agroforestry systems reduce the soil erosion, and increases the accumulation of organic matter, hence established a closed nutrient cycling which sustain the agricultural production for longer duration. Simultaneously, agroforestry systems are effective in enhancing food security, diversifying farm income and strengthening the resilience of community to climate change thus empower the farmers and provide an opportunity to combat poverty. However, there are numerous constraints including clear land tenure rights, market infrastructure and linkage, and lack of the traditional knowledge which influenced the adoption of agroforestry systems at global level. This immediately need to be addressed by implementing flexible legislation (such as National Agroforestry Policy 2014 adopted by India), capacity building and community involvement, value chain development and payment for ecosystem services. Overall, it is crucial to adopt low-carbon perennial agroecological practices like agroforestry in order to increase the CO2 abatement rate, improve the food, nutritional and livelihood security of smallholder farmers and contribute to a more environmental friendly and sustainable future.

“…Integrated and diversified production systems, such as agroforestry that integrate crop, livestock and forestry components in the same area, are considered a good example of land use with potential for mitigating GHG emissions. These systems have the potential to sequester CO 2 both in the above-ground biomass, mainly in the arboreal component, and in the soil, increasing the soil C stock at greater depths when compared with conventional agricultural systems [6][7][8][9].…”

Integrated production systems composed of trees, crops and pastures have shown good results in improving soil quality and the capacity to store carbon in the soil, being efficient in mitigating greenhouse gas emissions. Despite this, changes in carbon stocks and soil organic matter fractions in the initial stages of implementing an agroforestry system remain unclear. This study evaluated the carbon balance and the dynamics of soil organic matter fractions in an agroforestry system conducted over a decade. Total carbon, labile carbon, carbon from particulate organic matter, organic carbon associated with minerals and inert carbon were determined at depths 0–10 cm, 10–20 cm and 20–40 cm. Soil carbon stocks were also estimated for the 0–40 cm depth. Total carbon increased in the agroforestry system compared with a low-productivity pasture. The total carbon stock in the last growing season (68.57 Mg ha−1) was close to the original soil stocks under native Cerrado vegetation (76.5 Mg ha−1). After 10 years, there was a positive balance in the soil carbon stock of both the total carbon and the soil organic matter fractions. The successional agroforestry system is a good alternative to increasing soil total carbon stocks and labile and non-labile fractions of soil organic matter.

“…Afforestation and reforestation have been proposed as favorable options for removing atmospheric CO 2 through plant photosynthesis and storing it in tree bodies and soils [4][5][6][7]. Among the practical afforestation strategies, agroforestry is an important C storage strategy because it can provide both climate change mitigation and food recourses [8][9][10][11].…”

Agroforest systems have been widely recognized as an integrated approach to sustainable land use for addressing the climate change problem because of their greater potential to sequester atmospheric CO2 with multiple economic and ecological benefits. However, the nature and extent of the effects of an age-sequence of agroforestry systems on carbon (C) storage remain largely unknown. To reveal the influence of different aged poplar-crop systems on C stocks, we investigated the variation in biomass and C storage under four aged poplar-crop agroforest systems (3-, 9-, 13-, and 17-year-old) in the Henan province of China. The results showed that stand biomass increased with forest age, ranging from 26.9 to 121.6 t/ha in the corresponding four aged poplar-crop systems. The poplar tree biomass accounted for >80% of the total stand biomass in these poplar-crop agroforestry systems, except in the 3-year-old agroforestry system. The average stand productivity peaked in a 9-year-old poplar-crop system (11.8 t/ha/yr), the next was in 13- and 17-year-old agroforestry systems, and the minimum was found in 3-year-old poplar-crop stands (4.8 t/ha/yr). The total C stocks increased, with aging poplar-crop systems ranging from 99.7 to 189.2 t/ha in the studied agroforestry systems. The proportion of C stocks accounted for about 6, 25, and 69% of the total C stocks in the crop, poplar tree, and soil components in all studied agroforestry ecosystems, respectively. Our results suggested that the poplar-crop system, especially in productive and mature stages, is quite an effective agroforestry model to increase the study site’s biomass production and C stocks. This study highlighted the importance of agroforestry systems in C storage. It recommended the poplar-crop agroforest ecosystems as a viable option for sustainable production and C mitigation in the central region of China.
