Assessing Riverbank Erosion and Livelihood Resilience Using Traditional Approaches in Northern Bangladesh

Abstract

Bangladesh is a riverine country that is the most climate-change-vulnerable country in the world. Riverbank erosion adversely affects people and their livelihoods by damaging their homesteads, agricultural land, and causing economic, social, and psychological distress over time. Under these criteria, erosion control measures/approaches are vital for protecting erosion and crating livelihoods resilient. This study intends to assess riverbank erosion and livelihood resilience using traditional erosion control approaches by observing and surveying 118 riverine households in Rowmari, northern Bangladesh. The results show that riverbank erosion enormously damages household lands, socio-economic conditions, livelihoods, and resources, resulting in increased vulnerability. About 54.2% of the households utilize traditional approaches known as bundlings and 33.1% use both bundlings + bank vegetation that helps them resist erosion. Traditional erosion management approaches enhance resilience by safeguarding agricultural land, crop fields, production, and homesteads rapidly and sustainably, and by reducing damage to infrastructure, roads, embankments and transportation in the region. A probit model was also employed to explore factors that have influenced traditional erosion approaches. The factors such as age, education, family size, erosion experience, occupation, earning members, and farm size were meaningfully related to taking traditional erosion approaches. It is expected that the outcomes of the present research will help guide governmental agencies and policymakers and contribute to the construction of a sustainable riverbank erosion action framework in Bangladesh and other regions with similar problems.

Impact Assessment of Farmland Lease-Out on Rural Households’ Livelihood Capital and Livelihood Strategy

“…Third, these results provide new insights into how farmland lease-out affects rural household livelihood, and therefore complements the former conclusions that farmland lease affects livelihood [58][59][60]. This study contributes to the literature by improving our understanding of the influence of land on the livelihood framework.…”

Root Traits and Erosion Resistance of Three Endemic Grasses for Estuarine Sand Drift Control

“…Estuarine sand drift control has become the major challenge in the management of estuarine ecosystems [6][7][8][9]. In northern Bangladesh, traditional erosion management approaches have been applied to control riverbank erosion and enhance livelihood resilience [10]. The estuarine vegetation is very efficient at trapping drifting sand and reducing aeolian erosion [11], and its use is regarded as an effective ecological engineering method for sand drift control [12,13].…”

Environmental Change and Migration Aspirations: Evidence from Bangladesh

“…Under those circumstances, people might be willing to implement some type of adaptation or mitigation strategy (Koubi et al, 2022). For instance, in Bangladesh, people plant water resistant rice varieties and horticultural crops in the case of droughts (Al-Amin et al, 2019) and build walls using bamboo or sandbags to protect the riverbanks from eroding (Mamun et al, 2022). Yet, when they materialize, the impacts of such events are usually irreversible: complete and permanent destruction of (agricultural) land, houses, and infrastructure.…”
