Climate change and environmental degradation remain the most complex challenges that present future generations of humankind face raise several security risks have received relatively little attention in literature. This paper aims to review evidence arising from these Global South provide forward-looking perspectives on how increase resilience affected individuals communities. We see diverse land use strategies as a key element drive transformation towards greater sustainability resilience. propose rural should be geared promotion resource biodiversity conservation, development agroforestry, tree-based farming systems, diversification crops, utilization climate-resilient cultivars, neglected under-utilized plants.

Feeding climate and biodiversity goals with novel plant-based meat and milk alternatives

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Sept. 12, 2023

Plant-based animal product alternatives are increasingly promoted to achieve more sustainable diets. Here, we use a global economic land model assess the food system-wide impacts of dietary shift towards these alternatives. We find substantial reduction in environmental by 2050 if globally 50% main products (pork, chicken, beef and milk) substituted-net forest natural is almost fully halted agriculture GHG emissions decline 31% compared 2020. If spared agricultural within ecosystems restored forest, climate benefits could double, reaching 92% previously estimated sector mitigation potential. Furthermore, area contribute 13-25% restoration needs under target 2 from Kunming Montreal Global Biodiversity Framework 2030, future declines ecosystem integrity would be than halved. The distribution varies across regions-the on input China outcomes Sub-Saharan Africa South America. While replacement provides largest impacts, substituting multiple synergistic.

Achieving net-zero emissions in agriculture: a review

Environmental Research Letters, Journal Year: 2023, Volume and Issue: 18(6), P. 063002 - 063002

Published: May 16, 2023

Abstract Agriculture accounts for 12% of global annual greenhouse gas (GHG) emissions (7.1 Gt CO 2 equivalent), primarily through non-CO emissions, namely methane (54%), nitrous oxide (28%), and carbon dioxide (18%). Thus, agriculture contributes significantly to climate change is impacted by its consequences. Here, we present a review technologies innovations reducing GHG in agriculture. These include decarbonizing on-farm energy use, adopting nitrogen fertilizers management technologies, alternative rice cultivation methods, feeding breeding enteric methane. Combined, all these measures can reduce agricultural up 45%. However, residual 3.8 equivalent per year will require offsets from removal make net-zero. Bioenergy with capture storage enhanced rock weathering are particularly promising techniques, as they be implemented within result permanent sequestration. While net-zero technically available, come price premium over the status quo have limited adoption.

Immortalized Bovine Satellite Cells for Cultured Meat Applications

ACS Synthetic Biology, Journal Year: 2023, Volume and Issue: 12(5), P. 1567 - 1573

Published: May 5, 2023

For cultured meat to succeed at scale, muscle cells from food-relevant species must be expanded in vitro a rapid and reliable manner produce millions of metric tons biomass annually. Toward this goal, genetically immortalized offer substantial benefits over primary cells, including growth, escape cellular senescence, consistent starting cell populations for production. Here, we develop bovine satellite (iBSCs) via constitutive expression Telomerase reverse transcriptase (TERT) Cyclin-dependent kinase 4 (CDK4). These achieve 120 doublings the time publication maintain their capacity myogenic differentiation. They therefore valuable tool field, enabling further research development advance meat.

A systematic review of the definitions, narratives and paths forwards for a protein transition in high-income countries

Nature Food, Journal Year: 2024, Volume and Issue: 5(1), P. 28 - 36

Published: Jan. 3, 2024

Abstract The protein transition, aiming to rebalance intake between animal and alternative proteins, is gaining momentum in scientific policy discussions on food system transformation. Here, using a systematic review approach, we identified 33 articles that address challenges reducing the environmental impacts of production consumption, providing healthy diets for growing population preventing adverse effects industrial livestock systems. We found unclear definitions conflicting views reduction or replacement dietary lack attention systemic change by its macronutrient function. Three narratives were identified, namely, consumer narrative focusing consumption-based solutions targeting changes; techno-centred developing new, more resource-efficient systems; socio-technological intends transition agri-food from an animal-dominated regime regime. conclude should consider factors such as scale, initiating actors expected impact support complementary approaches.

Advancements in plant based meat analogs enhancing sensory and nutritional attributes

npj Science of Food, Journal Year: 2024, Volume and Issue: 8(1)

Published: Aug. 7, 2024

The burgeoning demand for plant-based meat analogs (PBMAs) stems from environmental, health, and ethical concerns, yet replicating the sensory attributes of animal remains challenging. This comprehensive review explores recent innovations in PBMA ingredients methodologies, emphasizing advancements texture, flavor, nutritional profiles. It chronicles transition soy-based first-generation products to more diversified second- third-generation PBMAs, showcasing utilization various plant proteins advanced processing techniques enrich experiences. underscores crucial role proteins, polysaccharides, fats mimicking meat's texture flavor emphasizes research on new sources improve product quality. Addressing challenges like production costs, taste, adequacy is vital enhancing consumer acceptance fostering a sustainable food system.

Most plant-based meat alternative buyers also buy meat: an analysis of household demographics, habit formation, and buying behavior among meat alternative buyers

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

The promise of novel plant-based meat alternatives (PBMAs) to lessen the health and environmental impacts consumption ultimately depend on market acceptance extent which they displace in consumers' diets. We use household scanner data provide an in-depth analysis PBMA buying behaviors. PBMAs buyers tend be young, single, female, college educated, employed, higher income, non-white. About 20% consumers purchased a at least once, 12% multiple occasions. 2.79% households only PBMAs. 86% also bought ground meat; however, spent about 13% less meat. Interestingly, after household's first purchase, did not fall. number for time fell over two year period studied, despite increase share market.

A meta-review of consumer behaviour studies on meat reduction and alternative protein acceptance

Food Quality and Preference, Journal Year: 2023, Volume and Issue: 114, P. 105067 - 105067

Published: Dec. 4, 2023

Transitioning away from meat-heavy diets towards more plant-based is beneficial to environmental and public health as well animal welfare. However, current food consumption practices do generally not follow this "protein transition". Therefore, we are in need of taking action accelerate the protein transition. We conduct a systematic review reviews (hereafter 'meta-review') provide an overview potential drivers moreover observe these findings policy perspective, resulting two main outcomes. First, meta-review mapped terms capability, opportunity, motivation. The latter appeared be given attention than other drivers. Motivational opportunity emerged most prominent. Especially Motives, emotions, awareness, taste, physical environment (redesign menus recipes by defaults, portion sizes visibility options) proved relevant with high evidence. Social cultural environment, development skills promising but remained under-researched. Second, present reviewed perspective. number studies that translated policymaking or included evaluations turned out limited. Besides, all only refer non-coercive interventions. finalizes prominent routes for future research policies. It highlights integrated framework, comparative focus on real-life long-term behaviour change, support coherent scholarly conclusions one hand evidence-based, action-oriented targeted at acceleration transition other.
