Developing land capability to reduce land degradation and disaster incident in Bendo Watershed, Banyuwangi

Abstract

Land degradation have caused decline in land productivity and triggering landslide incident in Bendo Watershed. This area has been selected as study area which represent characteristic upland area of the region. The research examines land capability analysis in order to reduce land degradation and disaster incidents and for sustainable use of land resources. The geomorphology approach was used along with sixteen of landform unit as unit sample. Further, artificial neural network models were used to classify land capabilities. Network architecture 10-8-1 was used on classification process due to the lowest error value factors. The findings of the study present that 20, 46% of Bendo watershed are prone to land degradation. Physical characteristic within area are contributing increasing land degradation. The capability classes of Bendo watershed ranges from class II to class VII. The upstream areas have erosion and intensive landslides as its limited factors, hence tend to have poor land capability classes. While the middle to downstream areas of Bendo watershed have better land capability classes with more diverse land use recommendations.

Land Capability and Suitability Assessment for Reducing Risk Disaster in Small Island: The Case of Sulabesi Island, Indonesia

“…This is because, as a small island, land resources are very limited, so it is important to determine the direction of development under land capability. Classification of land capability can support the sustainability of land use as well as efforts to reduce the negative impact of human activities on natural ecosystems [20], [25], [49]. Thus, in the development direction of Sulabesi Island, it is necessary to look at the distribution of built-up land cover at very low land capability and consider natural disaster risk factors.…”

Geomorphological mapping and landform characterization of Semeru volcano after the eruption in 2021

“…As an area limited by topographic conditions, The watershed is an ecological container where there is a reciprocal process between physiographic conditions, the environment, living things, and their use [15]. Based on this, watersheds are widely used as objects and study locations in the fields of planning [16,17], ecological [18,19], disaster [20][21][22], and landscape studies [23]. Changes of land conditions in the watershed affected by the eruption indicate changes in the nature and function of the landscape, therefore a comprehensive identification of the landscape needs to be done to determine the characteristics of the post-eruption land.…”

Erosão em áreas suscetíveis a desertificação no Semiárido: possibilidades de análise por meio da cartografia geomorfológica baseada em imagens de altíssima resolução

“…Sobre esse aspecto, a Geomorfologia pode contribuir para o entendimento de áreas degradadas por erosão e o seu grau de fragilidade (PRĂVĂLIE et al, 2020;BACHRI et al, 2021;NIKPOUR et al, 2022;JAAFARI et al, 2022), a partir de metodologias de análise que permitam a elaboração de diagnósticos e forneçam subsídios a ações de recuperação ambiental (CHELI, 2021). A cartografia geomorfológica, então, constitui-se em uma importante ferramenta ao possibilitar a interpretação de formas de relevo que indicam processos dinâmicos naturais e/ou antrópicos (LATOCHA, 2009;BISHOP et al, 2012), bem como a sua alteração ao longo do tempo.…”
