Seaweeds or macroalgae are multicellular photosynthetic organisms that can float freely or be attached to objects like rocks in the subtidal or intertidal part of the marine environment [1].Seaweed can also enhance the worldwide vegetable diet consumption and food supply chain.These include eradicating hunger (SDG2), promoting health and well-being (SDG3), ensuring access to affordable and clean energy (SDG7), addressing climate change (SDG13), and preserving life in the oceans (SDG14), all of which have resounding advantages that support other SDGs [8].It now accounts for 51.3% (34.7 MMT, wet weight) of all marine aquaculture worldwide, with China and eight other Asian nations dominating output (99.6%) [4,5] (see Figs.2 year? 1) [3].

Seaweeds or macroalgae are multicellular photosynthetic organisms that can float freely or be attached to objects like rocks in the
subtidal or intertidal part of the marine environment [1]. The production of seaweed has increased significantly over the past few
decades. It is predicted that just 2% of the ocean’s surface might be used to cultivate seaweed species, increasing current agricultural
food production twofold [2]. Growing seaweed has received a lot of interest as a sustainable source of bioenergy feedstock as it is more
productive (1600 g C m􀀀 2 year􀀀 1) than terrestrial plants (470 g C m􀀀 2 year􀀀 1) [3]. It now accounts for 51.3% (34.7 MMT, wet
weight) of all marine aquaculture worldwide, with China and eight other Asian nations dominating output (99.6%) [4,5] (see
Figs. 1–6).
According to ([8], seaweed farming can accomplish various objectives while advancing several of the Sustainable Development
Goals set forth by the United Nations (UN SDGs). These include eradicating hunger (SDG2), promoting health and well-being (SDG3),
ensuring access to affordable and clean energy (SDG7), addressing climate change (SDG13), and preserving life in the oceans (SDG14),
all of which have resounding advantages that support other SDGs [8]. In coastal countries, seaweed farming is a popular method for
developing a sustainable blue economy [9]. Seaweed can also enhance the worldwide vegetable diet consumption and food supply
chain.
