Swidden cultivation has been gradually transformed into other types of land-uses because of economic, political and social changes. In southern Chin State, Myanmar, the traditional swidden agriculture is being replaced by Wa-u (Amorphophallus bulbifer) cultivation in the fallows due to the increasing abandonment of swidden fallows and recent development of Wa-u market access. Also, the government of Myanmar promoted community participation in commercialized agriculture and forestry activities through community-based agroforestry systems. This study was carried out in two villages in southern Chin State, Myanmar to fill the research gap about the different Wa-u cultivation methods commonly applied in swidden cultivated fallows in term of cost-benefit and biomass analysis, socio-economically and environmentally contributing to community-based agroforestry systems in the region. The cost-benefit analysis showed that a modified traditional taungya method (mTTM) produced the best profit (228,571 Kyats per acre) among the cultivation methods. Also, the biomass analysis of tree vegetation showed that the Wa-u cultivated sites by mTTM has significantly higher basal area (21.1 ± 3.57 m²ha⁻¹) and biomass accumulation (65.4 ± 11.17 Mgha⁻¹) than other methods. As a result, Wa-u cultivation with maintenance of the tree stands could be promoted not only for socio-economic development but also for environmental conservation. This study suggests that Wa-u is promising as an intercrop species in agroforestry systems, and can be effectively incorporated into community-based agroforestry systems.

轮状转型过程中的农业综合农业评估：以缅甸南部钦邦为例

由于经济，政治和社会的变化，水耕耕种已逐渐转变为其他类型的土地利用。在缅甸钦邦南部，由于逐渐减少的休耕地和最近开发的Wa - u市场准入，休耕地的传统Wa - u（Amorphophallus bulbifer）种植取代了传统的耕作农业。此外，缅甸政府通过以社区为基础的农林业系统，促进了社区对商业化农业和林业活动的参与。本研究是在两个村庄南部钦邦，缅甸进行填补有关不同的研究空白娃- ü在成本效益和生物量分析方面，通常用于水耕休耕地的栽培方法，在社会经济和环境方面为该地区以社区为基础的农林业系统做出了贡献。成本效益分析表明，改良的传统taungya方法（mTTM）在耕种方法中产生了最高的利润（每英亩228,571缅元）。此外，对树木植被的生物量分析表明，mTTM的Wa - u耕地具有比其他方法显着更高的基础面积（21.1±3.57 m ² ha ^-1）和生物量积累（65.4±11.17 Mgha ^-1）。结果，Wa - u不仅可以促进社会经济发展，而且可以促进环境保护，促进维护林木的栽培。这项研究表明，Wa - u在农林业系统中作为一种间作种很有希望，并且可以有效地纳入以社区为基础的农林业系统中。
