Subject: Open sea cage culture of cobia: a catalyst for the blue economy along Indian coasts
Keywords: Blue economy, cobia, growth rate, mariculture, sea cages, wave height.
Abstract: The escalating global demand for fish protein necessitates the expansion of aquaculture from land to sea, facilitated by floating sea cages. In this study, the National Institute of Ocean Technology (NIOT), Chennai, Tamil nadu conducted a pilot-scale culture of hatchery-reared cobia seeds (Rachycentron canadum) in HDPE collar floating cages (9 m diameter with a cultivable volume of 320 m3 ). These cages were strategically deployed at Olaikuda (Gulf of Mannar, Tamil Nadu) and Thuplipalem (Andhra Pradesh), representing semi-protected (SP) and open sea (OS) environments respectively. The evaluation focused on growth performance, with cobia seeds stocked in cages at an initial biomass of 150 g/m3 (SP) and 154 g/m3 (OS), featuring an initial average weight of 32.49 ± 1.77 g and a total length of 15.6 ± 0.91 cm during stocking. In SP site, cobia exhibited significant growth, reaching an average weight of 3830 g in 270 days, with a specific growth rate (SGR) of 1.76% with a survival rate of 77%. In contrast, despite the longer culture period of 322 days at the OS site, lower average weight of 2550 g with an SGR of 1.35% with survival rate 62% at SP. Physicochemical and biological parameters at both sites remained within optimal ranges. Notably, the OS site experienced higher wave heights (ranging from 0.56 to 2.28 m); potentially impacting feeding patterns, high energy expenditure due to the exposed weather conditions resulted into reduced growth rate compared to the sheltered bay. This study aims to elucidate the comparative suitability of environmental settings and its economic feasibility for open sea cage farming

Subject: Harnessing the blue economy in Lakshadweep Islands through a sustainable tourism perspective
Keywords: Blue economy, community welfare, coral reefs, environmental management, sustainable tourism.
Abstract: This study delves into the dynamics of sustainable tourism in the Lakshadweep Archipelago, India, situated within the ambit of the blue economy framework. The study is centred around achieving a harmonious balance between economic growth and environmental conservation in the Lakshadweep Islands. It critically evaluates the tourism carrying capacity of the Islands, proposing a sustainable model that accommodates varying capacities, ranging from 12 beds in Chetlat to 434 beds in Kadmat, alongside a boating capacity of 207 in Bitra’s lagoon. A pivotal finding of this study is the urgent need for stringent environmental management measures, particularly focusing on the protection of fragile coral reef ecosystems against threats like plastic pollution. The limit of acceptable change is rigorously assessed, with coral reef health and water quality as crucial indicators. This study highlights the importance of implementing sustainable practices as a means to both safeguard the ecological integrity of Lakshadweep’s diverse islands and drive economic development. These findings play a crucial role in informing policy-making and guiding the alignment of tourism strategies in Lakshadweep with the overarching goals of environmental sustainability and enhancing community welfare.

Subject: Marine living resources – a blue future
Keywords: Blue economy, biodiversity, mariculture, marine bioprospecting, marine fisheries.
Abstract: India’s vast exclusive economic zone (EEZ) with its rich bounty of living and non-living resources, offers a great opportunity to expand its economy and food security, and could enable sustainable development and create resilient jobs. Marine fisheries, mariculture and marine bioprospecting are significant sectors which could act as the next big drivers of the GDP and public welfare. Marine biodiversity documentation sporadically requires innovative techniques using genomics in combination with underwater imagery to cover the full spectrum of marine living resources. Deep waters beyond 500 m depth are not optimally exploited and offer immense scope for commercial exploitation. The mariculture sector, despite the wide array of candidate species, is still in its infancy and requires the use of genetic engineering to develop breeds suitable for the mariculture systems. Employing new analytical technologies and a wide range of ‘multiomics’ tools can enhance the bioprospecting of numerous marine living resources, which have the potential to unravel hundreds of new compounds for human well-being. Ascertaining the continuity of the blue economy demands judicious management of oceanic resources through innovative and sustainable practices

Subject: India’s blue economy priorities: maritime sector
Keywords: Blue economy, decarbonization, emission abatement, maritime policy, port modernization.
Abstract: Blue economy is an all-inclusive concept based on seas and shorelines. India has prioritized its blue economy policies, and maritime development (logistics, infrastructure and shipping) is one of them. For charting the nation’s growth, a regular review of global trends and India’s plans is imperative. The major drivers or focal areas will be decarbonization and digitalization. Increased costs due to transformations, including technology acceptances and investments in port development to improve productivity will be on predictable paths. Shipping route alternatives (Northern Sea route, Belt and Road Initiative, etc.) will be in the discourses. Digitalization measures such as Maritime Single Window, Port Community Systems, etc. will get traction. India needs to shift gears with its Sagarmala projects and keep pace with the global transformative changes, especially on the digital front. Based on its new National Logistics Policy, logistics costs as a large head need to be considered along with performance metrics. This article juxtaposes global trends and indices, and lists a few issues that India must address.

Abstract: ‘Blue economy’ is becoming a buzzword for high economic growth with environmental sustainability, which is a reflection of the experiences of both developed and developing countries. A growing ‘blue voice’ emanates from a wide spectrum of countries about the efficacy of development strategies. Empirical evidence indicates that there is no ‘stylized fact’ about the contribution of blue economy to a country’s GDP. As a satellite account, the blue economy contributed 4.1% of India’s GDP in 2016. Accounting of the sector is important to identify priority sectors for policy planning in areas such as investment, employment, technology and other aspects of financial decisions. The blue economy value added in India is not only growing faster than the overall GDP, but is also becoming resilient to withstand adverse effects of the global exogenous shocks. Blue trade is becoming robust and is growing faster than the overall trade of a large number of littoral states. In India, blue trade shared more than 10% of the overall trade and openness of the sector was more than 100% during 2011–16. In blue trade, merchandise and services trade registered a favourable trade balance during 2008–22. The blue economy is likely to drive the Indian economy on a high-growth path after effective implementation of the National Blue Economy Advisory Council.

Abstract: In the contemporary scenario of global economic development, the blue economy stands as a beacon of potential, offering vast opportunities to accelerate economic growth. According to United Nations estimates, the blue economy generates between USD 3 and 6 trillion globally annually, supporting various sectors such as fisheries, aquaculture, tourism, energy, transport, maritime infrastructure and industries. The current contribution of the blue economy to India’s Gross Domestic Production (GDP) is ~4%, noticeably low for a nation surrounded by ocean on three sides, with a long coastline (8118 km) and an Exclusive Economic Zone (EEZ) of 2.02 million square km, constituting about 60% of country’s total area. Recognizing this potential, the government has identified the blue economy as a key growth driver. The Economic Advisory Council to Prime Minister has provided a policy framework emphasizing sustainable utilization and management of maritime sectors covering living resources, mineral and energy resources, services, coastal and maritime infrastructure, safety and global diplomacy, and marine spatial planning.

Abstract: Nowadays building occupies major energy share for its construction and operation. Many studies have been carried out on the enhancement of efficiency of the devices which in turn reduces operating energy consumption. However, the construction materials play a major role. The embodied energy for the building material, like brick, cement has increased day by day. Several investigations have already been made on the point of strength of alternate building materials. This paper analyses the embodied energy consumption of conventional wall and a bison wall. Also, the paper studies the thermal profile of a conventional wall and the bison wall building which is recently constructed. The internal and external thermal profile has been continuously recorded using thermal imager and reported. The temperature rise alone will lead to increased operating energy consumption in the building.

Abstract: Power generation through solar photovoltaic has grown at a faster rate in India. The estimated target by 2022 through solar PV rooftop as well ground mounted system is 100 GW. The life of the panel is 20 years. Many researchers have focused on increasing power output as well as panel size optimisation. The literature shows that the panel degrades 1% of the rated power every year. However, limited study is only available for degradation of panel on Indian climatic conditions. Many parameters, like dust, temperature, humidity have a role in the degradation of the panel. The paper has carried out a detailed investigation of the degradation of solar panel which has been put in use for the year 1998, 2007 and 2016.

Abstract: Irrigation is a major problem faced by farmers today. So automated irrigation system must be employed to overcome this. In India, agriculture plays an important role in development of food production. In our country, agriculture depends on the monsoons which are not sufficient source of water. Although there is much automated irrigation system, it cannot be implemented for fields having different crops. This proposed system implements the farmers need by incorporating soil moisture sensor and an embedded controller. This system can be implemented for fields having different crops that can be cultivated in a region. Farmers can monitor and control the field from remote locations using GSM technology.
