Climate change poses serious threat to aquatic foods: study | Lifestyle News
New Delhi: Billions of people in the developing world may face increased food and economic insecurity due to the threat climate change poses to aquatic food systems, unique research reveals.
An article published by Nature Food, titled “Compound Climate Risks Threaten Benefits of the Aquatic Food System,” was one of five to be published as part of the Blue Food Assessment (BFA) in one of the most comprehensive reviews industry to date.
The authors warn that without mitigating the effects of climate change by reducing greenhouse gas emissions, societies that depend on aquatic foods risk losing key contributions to livelihoods, economies, culture, health. and nutrition.
Research reveals, for the first time, the risk that climate change poses to the contribution of aquatic foods to human well-being and global development.
Without urgent action, capture fisheries – especially in regions such as tropical Africa, Central America and the Indo-Pacific – face the most serious risks.
Coastal and offshore aquaculture systems, on the other hand, face lower climate-specific risks, although freshwater aquaculture is exposed to high levels of risk.
“This is the first document of its kind to assess the risks that climate change poses to all aquatic foods, including freshwater and marine foods, aquaculture and wild catches, which provide jobs to more 100 million people and the livelihoods of more than three billion people worldwide, “said Michelle Tigchelaar, co-lead author and researcher at the Center for Ocean Solutions at Stanford University.
According to the study, countries that have traditionally been large emitters of greenhouse gas emissions do not necessarily face the greatest risk of climate change, which creates a need for shared responsibility between countries and regions. for climate-resilient aquatic food systems.
The countries of Southeast Asia, the Indo-Pacific and Africa, which depend heavily on aquatic foods to maintain their livelihoods and economies, face the “double jeopardy” of climate change which has a serious impact. negative impact on a critical economic sector.
In a high emissions scenario by 2050, the document found that more than 50 countries face the triple threat of high climate risks, exposure and vulnerability.
“Mitigation of carbon emissions and adaptation to unavoidable impacts are both urgently needed. We need to focus on the broader socio-ecological context of each country to ensure that climate solutions can build resilience and promote sustainable development, ”said William WL Cheung, co-lead author and researcher at the Institute of the Oceans and fisheries at the University of British Columbia.
“Early warning systems, disaster response plans, insurance schemes and safety nets will all be essential in building resilience to these growing threats. “
In addition to recommending actions that improve the climate resilience of aquatic food systems, the document also highlights the need for transformative action to reduce climate vulnerability in general, including the promotion of gender equity, reduction of poverty and the strengthening of governance systems.
