Sustainable consumption and production

Sustainable consumption and production (SCP) is at the core of the United Nations Sustainable Development Goals (SDGs), specifically addressed by SDG 12. This goal aims to "ensure sustainable consumption and production patterns," acting as a cross-cutting theme that feeds into other SDGs such as those related to climate change, poverty, health, and sustainable cities.

SCP involves using services and products in a way that minimizes environmental damage, preserves natural resources, and promotes social equity. The purpose is to decouple economic growth from environmental degradation, which means pursuing economic development in a way that can be sustained by the planet over the long term. SCP requires changes at all levels of society, from individuals to businesses to governments.

At the individual level, SCP implies making lifestyle choices that reduce environmental impact. This might include reducing, reusing, and recycling waste, choosing products with less packaging, and opting for more sustainable forms of transport like cycling or public transport.

For businesses, SCP entails adopting sustainable business models and practices. This could include improving resource efficiency, investing in renewable energy, designing products that are durable and recyclable, and ensuring fair labor practices.

At the government level, SCP involves implementing policies that support sustainable business practices and incentivize sustainable consumer behavior. This might involve regulations to reduce pollution, subsidies for renewable energy, and campaigns to raise awareness about sustainable consumption.

SCP also plays a role in several other SDGs. For example, sustainable production practices can help mitigate climate change (SDG 13) by reducing greenhouse gas emissions. Additionally, by reducing the pressure on natural resources, SCP supports the goals related to life below water (SDG 14) and life on land (SDG 15).

While progress has been made in certain areas, challenges remain in achieving the shift towards SCP. These include existing patterns of overconsumption, limited awareness about the impacts of consumption, and the need for technological innovation to enable more sustainable production.

The presence of plastic debris in the ocean is increasing and several effects in the marine environment have been reported. A great number of studies have demonstrated that microplastics (MPs) adsorb organic compounds concentrating them several orders of magnitude than the levels found in their surrounding environment, therefore they could be potential vectors of these contaminants to biota. However, a consensus on MPs as vectors of persistent organic pollutants (POPs) has not been reached since are opposing views among different researchers on this topic.

Following a decade of research on the environmental impacts of microplastics, a knowledge gap remains on the processes by which micro and nanoplastics pass across biological barriers, enter cells and are subject to biological mechanisms. Here we summarize available literature on the accumulation of microplastics and their associated contaminants in a variety of organisms including humans. Most data on the accumulation of microplastics in both field and lab studies are for marine invertebrates.

Describes psychological techniques that may offer an effective approach to preventing severe obesity from developing during puberty. Supports SGD goal: 2.2.2 Prevalence of malnutrition
Furthering SDGs 2 and 12, this report argues that feeding a population of 10 billion people by 2050 with a healthy and sustainable diet will be impossible without transforming eating habits, improving food production and reducing food waste.

Using a consumption-based Multi-Regional Input-Output (MRIO) model, we investigate the distinctive characteristics, self-efficiency or external dependency, of energy demand's water footprint in China's two biggest and fastest developing megalopolises. We find that energy demand water footprint in the Jing-Jin-Ji and the Yangtze Delta amounted to 2.41 and 9.59 billion m³of water withdrawal respectively in 2010, of which 848.06 and 973.91 million m³was consumed. Among all energy products, electricity contributed the largest share to the energy sector's water footprint in both regions.
The world food price crisis in 2007/08 has aroused worldwide attention to the global food price volatility and food self-sufficiency issues. This paper modelled the entire environment of food production and transaction from a holistic view by a Food-Energy-Water (FEW) nexus in order to reveal the hidden connections related to the food self-sufficiency issue, including the interdependencies of food production with its restraining factors (hybrid energy, hybrid water), other production sectors, and international exchanges.

Microplastics are widespread contaminants, virtually present in all environmental compartments. However, knowledge on sources, fate and environmental concentration over time and space still is limited due to the laborious and varied analytical procedures currently used. In this work we critically review the methods currently used for sampling and detection of microplastics, identifying flaws in study design and suggesting promising alternatives.
Plastics entering the environment will persist and continue to degrade and fragment to smaller particles under the action of various environmental factors. These microplastics (MP) and nanoplastics (NP) are likely to pose a higher environmental impact, as well as they are more prone to adsorb organic contaminants and pathogens from the surrounding media, due to their higher surface area to volume ratio. Little known on their characteristics, fragmentation, distribution and impact on freshwater ecosystems.

One of the key Sustainable Development Goals (SDG) set by the United Nations (UN) aims by 2030 to “end hunger, achieve food security and improved nutrition and promote sustainable agriculture”. Fertilizers will play a pivotal role in achieving that goal given that ~90% of crop production growth is expected to come from higher yields and increased cropping intensity. However, materials-science research on fertilizers has received little attention, especially in Africa.
