摘要

在全球范围内,土地退化已成为确保粮食和土壤安全的一个令人关切的问题。2012年,联合国(UN)开始了实现土地退化中性(LDN)星球的征程,孟加拉国在2015年表示有兴趣成为LDN目标制定计划的一部分,并制定了到2030年扭转土地退化的六个LDN目标。本研究的目的是调查孟加拉国在实现LDN目标方面的进展情况。我们的调查显示,与前几年相比,只有土壤碳储量有所增加。然而,森林砍伐、山体滑坡、土壤侵蚀、河岸侵蚀和盐碱化入侵的速度有所增加。土壤治理薄弱和没有纳入土壤保持立法是孟加拉国土壤健康恶化的主要原因。此外,地缘政治难民也应该负责,因为他们正在破坏山区和森林地区的定居点和农业。我们建议研究人员在全国范围内开展更多的研究工作,因为关于土地退化的最新信息很少。我们还建议理事机构立即制定强有力的土壤治理和土壤保持法,以制止孟加拉国的土地退化和确保土壤安全。

Land degradation neutrality concerns in Bangladesh

Globally, land degradation has become a concerning issue for ensuring food and soil security. In 2012, the United Nations (UN) started their journey to achieve a land degradation neutral (LDN) planet, and Bangladesh showed her interest to be a part of LDN target setting program in 2015 and set six LDN targets to reverse land degradation by 2030. The aim of this study is to investigate the progress of Bangladesh towards achieving LDN targets. Our investigation reveals that only the soil carbon stock has improved compared to the previous years’. However, the rate of deforestation, landslides, soil erosion, riverbank erosion, and intrusion of salinity has increased. Weak soil governance and no inclusion of soil conservation legislation are the key reasons for deteriorating the soil health of Bangladesh. Moreover, the geopolitical refugees should also be held responsible as they are destroying the hill tracts and forest areas for settlements and agriculture. We suggest the researchers to conduct more research works together at national scale as there are few latest information available on land degradation. We also recommend the governing body to establish a strong soil governance and soil conservation act immediately to halt land degradation and for ensuring soil security in Bangladesh.
