The consideration of alternative sources of material for construction is imperative to reduce the environmental impacts as two-fifths of the carbon footprint of materials is attributed to the construction industry. One alternative material with improved biodegradable attributes which can contribute to carbon offset is bamboo. The commercialisation of bamboo in modern infrastructures has significant potential to address few of the Sustainable Development Goals (SDGs) itemised by the United Nations, namely SDG 9 about industry, innovation and infrastructure. Other SDGs covering sustainable cities and communities, responsible consumption and production and climate action are also indirectly addressed when utilising sustainable construction materials. Being a natural material however, the full commercialisation of materials such as bamboo is constrained by a lack of durability. Besides fracture mechanisms arising from load-induced cracks and thermal modification, the durability of bamboo material is greatly impaired by biotic and abiotic factors, which equally affect its natural rate of degradation, hence fracture behaviour. In first instance, this chapter outlines the various factors leading to the durability limitations in bamboo material due to load-induced cracks and natural degradation based on recent findings in this field from the author's own work and from past literature. Secondly, part of this chapter is devoted to a new approach of processing the surge of information about the varied aspects of bamboo durability by considering the powerful technique of artificial intelligence (AI), specifically the artificial neural network (ANN) for prediction modelling. Further use of AI-enabled technologies could have an impactful outcome on the life cycle assessment of bamboo-based structures to address the growing challenges outlined by the United Nations.

By bringing together aspects of sustainable forest management, population health, and local livelihoods, the purpose of this study was to characterize how household dependence on forest resources changes through three phases: the period before HIV became a problem in the household, the period during HIV-related morbidity, and after AIDS-related mortality.

Sixty semi-structured interviews were conducted with members of unaffected and HIV/AIDS-affected households in four case study districts in Malawi.

This study demonstrates that the relationship between HIV/AIDS and dependence on specific forest resources appears to correspond closely with the stage of the disease. Firewood and water were consistently ranked as being one of the three most important resources, regardless of HIV-affectedness. During the morbidity phase, respondents reported their need for medicinal plants increased substantially, along with other resources. The importance of timber increased significantly after HIV-related mortality.

Interview respondents themselves suggested key interventions that would assist households in the HIV/AIDS-mortality phase, in particular, to obtain the forest resources they require. These interventions could address the impacts of HIV/AIDS on the sustainability of important resources, compensate for a decreased availability of household labor, and foster greater access to these resources for vulnerable households in the four study sites.

In spite of the fact that forest resources can play a crucial role in enabling a household to control and adapt to the disease, research on the environmental dimensions of HIV/AIDS remains limited. This chapter helps to address this knowledge gap, suggests practical, innovative interventions that could alleviate some of the disease burden on rural Malawian households, and offers insight into potential areas of further inquiry in this research domain.

Chilika Lagoon is the largest brackishwater lagoon in the Indian subcontinent, situated at latitude 19°28′ and 19°54′ north and longitude 85°05′ and 85°38′ east (Fig. 2.1). The lagoon extends from the southwest corner of Puri and Khurdra districts to the adjoining Ganjam district of Orissa state. The pear-shaped lagoon is around 64.3km long and its width varies from 18to 5km. It is connected to the sea through irregular water channels with several small sandy and usually ephemeral islands (CDA, 2008). The average lagoon area is 1,055km² which increases to 1,165km² during the rainy season and shrinks to 906km² during the summer season. Chilika Lagoon becomes less saline during the rainy season due to flood waters from 52 rivers and rivulets. It becomes more saline during the dry season as the supply of flood water is cut off when the south wind begins to blow and saline waters enter from the Bay of Bengal at high (Patro, 2001). The lagoon has three hydrologic subsystems (Mahanadi delta, western catchments, and the Bay of Bengal) influencing the hydrological regimes as shown in Fig. 2.1. The total inflow of freshwater from the Mahanadi delta has been estimated to be 4,912 million cubic meter, accounting for 80 percent of the total water flow. The maximum discharge of 3,182 million cubic meter comes from Makara River, followed by Bhargavi River (1,108 million cubic meter) and Luna River (428 million cubic meter) (CDA, 2008). Meanwhile, the western catchments account for 20 percent of the total fresh water flow.

Composites based on fiber are commonly used in high-performance building materials. The composites mostly use petrochemically derived fibers like polyester and e-glass, due to their advantageous material features like high stiffness and strength. All the same, these fibers also have important shortcomings related to energy consumption, recyclability, initial processing expense, resulting health hazards, and sustainability. Increasing environmental awareness and new sustainable building technologies are driving the research, development, and usage of “green” building materials, especially the development of biomaterials.

In this chapter, the natural fiber evaluation approach is applied, which covers a diverse set of criteria. Consequently, the comparative assessment of diverse natural fiber types is applied through the use of an expert decision system approach. The best performing fiber choice is made by comparatively evaluating the materials related to green building. The proposed fiber can be used and applied by green building material manufacturing companies in various countries or locations as a reference when selecting the fiber with the best performance.

The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

Tourism acts as a stimulant in rural poverty reduction and inclusive socioeconomic development. Sustainable tourism can significantly contribute to the economic diversification and local economic development of rural areas with its ability to create jobs and encourage infrastructural development focusing on preserving the environment, culture and indigenous groups. The detrimental effects of tourism on the economy, society and culture have shifted attention to sustainable travel. As a result, terms like ‘tribal tourism’, ‘ecotourism’ and ‘sustainable tourism’ have become popular. Inclusive engagement is a crucial agenda item in future tourism development and a major concern of many international organisations, including the United Nations. This chapter focuses on exploring the tribal communities and their involvement in sustainable tourism initiatives with an overarching focus on the role of the indigenous community and their skill sets in creating sustainable livelihoods through tribal tourism. Apart from creating direct and indirect employment opportunities, tribal tourism will support the growth of locally produced goods and have significant multiplier effects as capability-building initiatives will give impetus to the community's socioeconomic development.

Additionally, the sector offers notable advancements in the development of the tribal region. Tribal tourism will help people comprehend the significance of the ecosystem, local biodiversity and emission control activities on a deeper level (Thanikkad & Saleem, 2021). This chapter explores the indigenous tribes of Kerala and their ethnic skill sets, capabilities and means of livelihood. Further, the discussion on how the tourism domain promotes inclusive engagement of these tribes and aids in mapping skill sets, livelihood and inclusive engagement through tourism initiatives is explored.
