“…Several strategies can be used to reduce the effect of the tree canopy on solar radiation, such as forest species by adjusting the canopy size, architecture and leaf geometry [40]. Several studies showed that the dynamics of solar radiation in understorey forest species differed, 41.5% in the amount of solar radiation available in understorey Melaleuca cajuputi, Peltophorum dubium and Eucalyptus grandis [41]. Thus, identifying the forest species that are most appropriate to compose an agroforestry system to produce a balance between the amount of solar radiation intercepted by the tree canopy and the amount transmitted downward.…”

Climate change is a global problem that has an impact on food production. Protein needs for people in developing countries such as Indonesia have not been fulfilled optimally. Indonesian people’s protein consumption is still at 65.7%, much lower than it should be. The development of soybean cultivation as a source of vegetable protein is very potential. This article aims to examine the role of soybean agroforestry to meet human protein needs and as an effort to mitigate climate change.In Indonesia, soybean development is constrained by people’s views; soybean is not the main crop and the rate of land conversion. An effort to overcome the limitation of optimum land according to the growing season is the development of soybean cultivation under forest stands as an agroforestry system. In Indonesia, there are production forests, including teak, pine, sengon, and resin, especially in teak, pine, and sengon forests, soybean cultivation with agroforestry systems has developed. The main obstacle to cultivation in the agroforestry system is low light due to the shade of the tree canopy. It requires efforts: tree spacing, especially between rows, trimming the tree canopy when the canopy is getting tighter, and low light tolerant plant varieties. Soybeans are low-light tolerant plants. The national average soybean production of about 1.5 tons ha-1 can be achieved in teak-based agroforestry systems up to 3-4 years old tree, pine-based up to 3 years old, and sengon-based up to 5 years old. The agroforestry system has the potential as land for the cultivation of organic plants in mitigating the impacts of climate change.

“…To overcome farmland shortage, understory P. notoginseng was developed as a new ecological planting model [ 17 ]. A related study investigated the production patterns of black oats grown under four different woodland types in southern Brazil and found that black oats grown under P. rigida were the most productive [ 18 ]. Agroforestry systems have been successfully practiced and researched on many species.…”

Understory planting affects the growth environment of tea plants, regulating the tea plant growth and the formation of secondary metabolites, which in turn affects the flavor of Xiaobai white tea. The present research adopted biochemical composition determination, widely targeted volatilities (WTV) analysis, multivariate statistical analysis, and odor activity value (OAV) analysis to analyze the characteristics in the macro-composition and volatile compounds of understory white tea. The sensory evaluation results indicated that understory Xiaobai white tea (LWTs) was stronger than ordinary Xiaobai white tea (PWTs) in terms of the taste of smoothness, sweetness, and thickness as well as the aromas of the flower and sweet. Understory planting reduced light intensity and air temperature, increased air humidity, organic matter, total nitrogen, and available nitrogen contents, which improved the growth environment of tea plants. The phytochemical analysis showed that the water-extractable substances, caffeine, flavonoids, and soluble sugar contents of understory tea fresh-leaf (LF) were higher than those of ordinary fresh-leaf (PF). The phytochemical analysis showed that the free amino acids, theaflavins, thearubigins, water-extractable substances, and tea polyphenols contents of LWTs were significantly higher than those of PWTs, which may explain the higher smoothness, sweetness, and thickness scores of LWTs than those of PWTs. The 2-heptanol, 2-decane, damasone, and cedar alcohol contents were significantly higher in LWTs than in PWTs, which may result in stronger flowery and sweet aromas in LWTs than in PWTs. These results provide a firm experimental basis for the observed differences in the flavor of LWTs and PWTs.
