“…Gher farming is a unique indigenous innovation, which is suitable for the cultivation of prawn, fish, rice and dike crops. The widespread development of the gher farming system in coastal regions of Bangladesh was likened to a 'blue revolution' [19], which in turn refers to the rise of aquaculture as an important agricultural activity [20].…”

This paper measures energy performance, Total Factor Energy Productivity (TFEP), technical change (TC) and energy efficiency change (EEC) of the gher (prawn-carp-rice) farming system using a unique panel data of 90 farmers covering a 14 year period (2002–2015) from southwest Bangladesh by employing a stochastic input distance function approach. Results reveal that all inputs contribute significantly to energy productivity of the gher farming system with male labor energy input being the major contributor followed by energy from machineries, seeds and chemicals. Energy performance of the High Yielding Variety (HYV) rice enterprise is highly efficient whereas the prawn enterprise is highly energy inefficient. Furthermore, energy performance of the HYV rice enterprise improved significantly over time. Significant competition exists between HYV rice and prawn enterprises as well as prawn and carp enterprises. Experience and education significantly improve energy efficiency whereas gher area and household size significantly reduces it. TFEP grew at the rate of 2.56% per annum (p.a.) solely powered by technical progress at the rate of 2.57% p.a. Gher system can be sustained in the long-run driven by technical progress and improvements in energy productivity of the HYV rice enterprise. Policy implications include investments in R&D and education targeted at the gher farmers.

“…Often technology is evoked to solve problems of water scarcity. In the water domain, recent 'technological optimist' policies range from the search for the new 'blue revolution' and more irrigation systems for Africa, 22 and the crop biotechnology revolution, to-at their most far-fetched-expansion into space to mine Mars for water. There is no doubt that technologies have key roles to play in addressing water problems.…”

Water is essential for human well‐being and is a basic asset for productive livelihoods in many developing countries. It is also key to realizing most of the Millennium Development Goals (MDGs). Although the water MDG was met in 2010, 768 million people around the globe still lack access to safe and adequate water. Huge disparities continue to exist in access between rural and urban areas and rich and poor, as well as inherent social and gender inequalities. We argue that debates about access have so far paid insufficient attention to the long‐term sustainability of systems and services for accessing water. They have also neglected issues concerning uncertainty and social, environmental, and technological dynamics—particularly through addressing power imbalances and enhancing equity. There are two main reasons for this. One, discourses on access tend to be globalized and general, often disconnected from people's lived realities. Two, the dynamic interaction among social, technical, and ecological/hydrological dimensions of water across multiple scales is not adequately taken account of. There is a variety of different pathways in which water systems of access might develop. There are also multiple understandings and framings of water, and the gathering of knowledge about such diverse understandings implies that appraisal of access needs to broaden up to include a wider range of perspectives to inform policy and political discourse. We thus introduce the concept of ‘Liquid Dynamics’ to capture an understanding of sustainability that takes on board issues of uncertainty, complexity, local knowledge, equity, gender, and power relations.

“…Blue revolution is often referring to the rapid development of aquaculture and to the creation of an agricultural activity with a high productivity (McGinn, 1998;Costa-Pierce, 2002;Movik, Mehta, Mtisi, & Nicol, 2005;Simpson, 2011). This blue revolution is responsible for the increment in food production worldwide (Béné et al, 2016;FAO, 2020).…”

Introduction: “Blue Economy” refers to ocean-based economies with a sustainable approach. It focuses in smaller carbon footprints and efficiency, principles that can be applied to aquaculture. However, it has been difficult to develop successful blue economy projects in sea urchin aquaculture. Objective: To compare URCHINOMICS (Norway) and ARBACIA (Argentina), two aquaculture projects with different business models. Methods: We used publicly available information to compare both companies on the basis of their value proposition and tensions (e.g. cultural, social economic and technological). Results: To be successful, sea urchin aquaculture requires development of appropriate technology, open innovation and cooperation of people with different academic, business and organizational backgrounds. Conclusion: The ultimate success of these and similar companies will depend on free interaction of experts from multiple fields and on technological innovation.
