PurposeMass movements, especially landslides, are a recurring natural phenomenon and are an integral part of any geological/geomorphological cycle of landform development through sequential development of slopes in any elevated region and especially in young fold mountain chains. The purpose of this paper is to develop and evolve cheap, affordable, environment friendly and ecologically sustainable techniques of landslide disaster management and prevention.Design/methodology/approachThe study is based on extensive research and field observations of various landslide management projects over the past decade and includes an intensive review of literature from secondary sources.FindingsLandslide management aims to facilitate, and as far as possible accelerate the ongoing process of development on a sustainable basis, by preventing (reducing) the loss of lives and property by applying modern science and technology and taking appropriate measures and safety precautions at the right place at the right time. Landslide management, even in the most developed countries, has suffered from lack of adequate financial resources. Bioengineering offers an environment friendly and highly cost and time effective solution to the slope instability problems in mountainous and hilly areas.Practical implicationsThe paper aims to initiate and encourage research in the field of landslide management with the viewpoint that green technology is a clean and affordable technology (both financially and ecologically).Originality/valueThe paper shows that bioengineering is highly cost effective and has very high cost‐benefit ratio. Bioengineering techniques when used in combination with civil and social engineering measures reduce the overall cost of landslide mitigation considerably which is the key factor for developing nations. Bioengineering has a very high success rate and is much more sustainable, eco‐friendly and affordable than other available options.

PurposeThis paper aims to promote sustainable development through disaster management.Design/methodology/approachThe study is based on extensive field observations and intensive review of literature from secondary sources.FindingsIn recent times landslides have increased both in frequency and intensity and have assumed catastrophic and disastrous proportions, causing extensive damage to life and property and posing great problems and serious challenges to man and his development process. This increase has been triggered by a combination of several attributes (geological, morphometric, climatic and anthropogenetic) that directly or indirectly cause slope instability, most of which (if not all) are either man‐made or man‐accelerated. Thus, most of the disasters are natural events aggravated by undue human intervention. Man, through his intervention, has accelerated this natural process and his encroachment on the relatively unsafe areas has turned them into disasters. The effect of man on natural processes can be judged from the fact that the frequency of natural disasters/hazards has recorded more than a fivefold increase just in the last two decades, despite all the hue and cry that has been going on all round the world. The economic losses on account of such happenings have shot up by over 3.5 times, and the rise in total insured losses is about six times and, with the present trends (particularly of ignorance, carelessness, lack of will and finances, greed, increasing population and also human demands) and situations, it can safely be predicted that the worst is still to come.Practical implicationsLandslides are a natural phenomenon and every year hundreds of major and minor landslides occur in the hills, though only a few major ones are reported by the print and electronic media, and still fewer are studied and/or analyzed in some detail. The present paper presents a valuable insight into various aspects of landslide management to spread awareness, to educate and sensitize people towards better and effective landslide hazard mitigation and thereby ensure people's participation in disaster management. It also aims to initiate and encourage research in the field of landslide management.Originality/valueThe paper hopes to minimize losses due to landslides through better knowledge and enhanced levels of understanding of the phenomenon and its management.

PurposeThe purpose of this paper is to attempt to generate a better, systematic and scientific understanding of the basic reasons behind slope instability to help in developing the basic principles of landslide hazard zonation, monitoring and forecasting of landslide hazards for better and more effective landslide hazard mitigation and management.Design/methodology/approachThe study is based on extensive field observations and intensive reviews of literature from secondary sources.FindingsMass movements especially landslides as they are known to common man are a recurring natural phenomenon and are an integral part of any geological/geomorphological circle of landform development through sequential development of slopes in any elevated region and especially in young fold mountain chains.Practical implicationsThe paper presents a valuable insight into the basic reasons behind a landslide to spread awareness, to educate and sensitize people towards better and effective landslide hazard mitigation and thereby ensure people's participation in disaster management. It also aims to initiate and encourage research in the field of landslide management.Originality/valueLandslides occur frequently and without any appreciable warning as such causing havoc and often insurmountable damage to life and property but despite their uncertainty, their causative factors and indicators of slope instability are very well known to an extent that the magnitude of these events, susceptible areas, the timing of such events and their potential impact can be studied, analyzed and evaluated on the basis of past occurrences and existing knowledge to mitigate their impact. The real value of the present study is to minimize losses due to landslides through better knowledge and enhanced levels of understanding of the phenomenon and its management by simply avoiding those particular reasons that could lead to slope instability problems.

PurposeA woman's nutritional status significantly determines her overall well-being. The authors critically examine the trends — including socioeconomic disparities — in undernutrition among Muslim women in India, a notably socio-economically disadvantaged group. The authors also investigate trends and variations across the dimensions of caste, place of residence (rural/urban), education, economic status and geographic regions.Design/methodology/approachThe analysis leverages the nationally representative National Family Health Surveys (NFHS) of India conducted between 1998 and 2021. The authors examined poor–rich ratios, concentration indices, disparity ratios and predicted probabilities of being underweight (captured using Body Mass Index).FindingsFrom 1998 to 2021, there has been a decline in undernutrition prevalence among Muslim women. However, stark socioeconomic variations persist. While the prevalence has decreased over time across all socioeconomic groups, disparities — both within and between groups — remain significant and, in many cases, have expanded. For certain socioeconomic subgroups (e.g. Muslim women with no formal education or those in the Central and Northeast regions), the disparity doubled between 1998 and 2021. In regions like the South, where undernutrition prevalence is low or has reduced, disparities remain significant and generally have increased.Originality/valueTo the authors' knowledge, the study is the first to provide a comprehensive examination of the prevalence, trends and socioeconomic disparities in undernutrition among Muslim women in India over the past two decades.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-04-2023-0320
