“…Naturally, these nutrient contents depend on the decomposition of organic matter. That is, higher decomposition of organic matters in the soil leads to higher concentrations of P and K in the soil, as we observed in our agroforestry plots, similar to other studies (Haque et al, 2014;Mahmud et al, 2018).…”

“…We can speculate that plantation forest floors conserve soil MC because increases in plant cover reduce water losses from soil evaporation, but we would need additional sampling at more dates for confirming this pattern. Nonetheless, other studies have also observed that forested soils contain higher soil MC than deforested areas (Haque et al, 2014).…”

“…The Chittagong Hill Tracts (CHTs) from south-eastern Bangladesh are particularly sensitive to soil degradation because the area is characterized by steep slopes, often reaching above 40%, which may increase soil erosion and, consequently, soil fertility losses (Lenka et al, 2012). Besides, annual crop production by slash-and-burn practice in steep slopes adversely affected the forest genetic resources and hampered ecosystem functioning (Biswas et al, 2012;Haque et al, 2014).…”

“…Different studies have addressed how soil properties vary across land use systems, and there is a broad consensus now that slash-and-burn practices impoverish soil nutrients in the CHTs (Biswas et al, 2012;Haque et al, 2014; K. R. Islam & Weil, 2000;Mahmud et al, 2018). Here we seek to understand the potential of agroforestry as a soil restoration technique because its impact over CHT soil nutrients still has to be quantified.…”

Increasing land demands for food production has led to large-scale soil degradation in the hilly regions of south-eastern Bangladesh. An intensification of slash-and-burn techniques, where fallow intervals have shortened considerably in recent years, has led to widespread losses in soil quality. Here we sought to test to what extent do current agroforestry practices in the area, compared with current reforestation efforts, can ameliorate different physicochemical soil properties after the abandonment of slash-and-burn practices. We observed that concentrations of soil organic matter (4.75%), available phosphorous (12.17 μg g −1 ) and exchangeable potassium (0.39 mg kg −1 ) in agroforestry plots were significantly higher than in reforestation (3.18%, 6.50 μg g −1 and 0.21 mg kg −1 , respectively) or slash-and-burn plots (1.83%, 5.90 μg g −1 and 0.03 mg kg −1 , respectively). While reforestation and agroforestry may both serve to restore soil functions but we observed higher benefits in the latter system. Thus, agroforestry systems may be a suitable land management system for replacing ancestral slash and burn techniques but care should be taken to diminish soil compaction.

“…The forest area in Bangladesh is also reduced day by day. According to Haque et al (2014), deforestation or the insufficient forest area can't absorb properly. However, it is generally said that if the source of CO2 fact identifies properly then it will be mitigated.…”

The current study analyzed the optimum solution to mitigate CO2 emission in Bangladesh. The significant factor of this study is agricultural productions and activities in Bangladesh are the superior carbon absorber. To estimate the effective result and findings this perusal conducts the Generalized Method of Movement with considering agricultural productions as a key variable to mitigate the CO2 emission. The econometric result finds that agricultural production reduces carbon emission in selected models. An increase the agricultural activities and green harvesting significantly reduce CO2 emission. Whatever, the empirical result also states that increasing agricultural production is not only a productive way to mitigate CO2, also, that CO2 could be mitigated to invest in agriculture, provide initiative or subsidies in the agriculture sector. The current study provides a substantial way to mitigate carbon dioxide without any harms of economic growth. Contribution/ OriginalityThis study is the first attempt to investigate the role of agriculture to relieve the CO2 emission in Bangladesh. It will also fill the gap of literature in this field in the country.
