What is the key feature of ecosystem-based engineering in sustainable agriculture?

Rely on part of an article "Research gaps include developing cost-effective culture systems capable of successfully handling huge amounts of wastewater while maintaining consistent biomass quality and fertilizer removal rates".

Although microalgae provide promising options for wastewater treatment through nutrient uptake and biomass generation, scaling these technologies remains difficult. Research gaps include developing cost-effective culture systems capable of successfully handling huge amounts of wastewater while maintaining consistent biomass quality and fertilizer removal rates [301]. Additional research on the size of wastewater treatment and microalgal production is required for future process advancements. Although small-scale microalgae cultivation and downstream processing can be expensive, products with niche markets and higher market prices may be a viable alternative for agricultural wastewater treatment in the future [302]. Small-scale wastewater treatment in local agricultural regions could be planned to collect high-quality microalgae for processing in large-scale multiproduct biorefineries. If small-scale production is not feasible, centralized wastewater treatment facilities supplying large-scale microalgae feedstock for several biorefineries may be a viable option for future waste-based profit generation.

What policy approach enhances sustainable waste management in agriculture?

the anwser is rely on Finally, strategies to manage and valorize AD effluent in a cost-effective and sustainable way, especially for small and urban setups, are nascent. Addressing these gaps is essential to enable the transition of AD from a promising concept to a fully integrated solution in circular bioeconomy models.

AD is a reliable approach to producing eco-friendly energy from food waste and agricultural residues recovered from the production and distribution phases. Using this biological process, food waste can be sustainably used rather than disposed of using traditional techniques, which helps address contemporary ecological and environmental concerns. Additionally, it yields high-value products, namely biogas (biomethane), which is used to generate heat and energy required for food processing, and digestate, which has potential use in agronomy as a soil conditioner or an organic fertilizer. Despite the substantial progress in AD research and application, several important research gaps persist. Digestate valorization still lacks scalable, standardized approaches that ensure agronomic efficiency and environmental safety. Pretreatment technologies for lignocellulosic materials remain limited by economic and technical feasibility for decentralized systems. Operational optimization under real-world variability, particularly through automated or adaptive control systems, is underdeveloped. Economic and environmental assessments for small-scale, decentralized AD systems are inadequate, impeding broader adoption.

Conclusions This review emphasizes the critical importance of adaptation engineering in making sustainable development possible within agricultural systems, particularly to mitigate the growing effects of climate change on agricultural communities and production worldwide. To promote resilience and sustainability, new and integrated approaches should be utilized to avoid climate effects and transform agriculture into a circular and regenerative system. Adaptation engineering provides end-to-end, integrated solutions that enable the transition from linear to circular agricultural systems. Firstly, in the spirit of climate change mitigation, it advocates for using climate-smart agriculture practices, such as precision agriculture, agroforestry, and drip irrigation. These help to reduce greenhouse gas emissions, increase carbon sequestration, and improve the efficiency of natural resource utilization from production to post-harvesting activities. Such systemic integration ensures that climate mitigation interventions are embedded along the agricultural value chain. Second, sustainable waste management in agriculture, which is crucial for circularity, is dealt with adaptation engineering in the form of transforming organic waste streams into useful inputs. Techniques such as anaerobic digestion, microalgae cultivation for bioenergy, and hydroponic recycling of nutrients close the resource loop. These solutions make recovering energy, nutrients, and water possible, thus transforming waste into a resource at every production, processing, and consumption phase. Third, the universal application of circular economy logic to the entire agricultural system implies comprehensive resource management from input supply through post-consumer recovery. Adaptation engineering allows for achieving this goal by encouraging strategies like crop rotation, intercropping, and minimal tillage that increase soil renewal and minimize the use of synthetic inputs. Adaptation engineering also allows for community-scale approaches, such as collective farm infrastructure, cooperative composting, and local food systems capable of localizing production, minimizing supply chain emissions, and facilitating equitable resource allocation. By implementing end-to-end circular management principles, where all inputs are maximized, all outputs are recycled, and all stakeholders are involved, adaptation engineering supports the creation of strong, resilient agricultural systems. These systems meet present food and resource needs while maintaining ecological integrity and long-term sustainability. With climate mitigation, waste valorization, and closed-loop resource utilization joined together, adaptation engineering presents a futuristic roadmap to inclusive, circular, and future-proof agriculture. In light of these findings, it is recommended that policymakers implement targeted strategies to promote adaptation engineering in agriculture through supportive policy frameworks, financial incentives, and investment in innovation and training. Practitioners, including extension workers and farm managers, should be encouraged to adopt technologies such as anaerobic digestion, hydroponics, and microalgae-based systems to reduce environmental impact and enhance productivity. In addition, establishing multi-stakeholder platforms that link research institutions, farming communities, and government bodies can accelerate the co-development and deployment of context-specific solutions, ensuring the widespread and equitable adoption of sustainable agricultural practices.

What is the primary advantage of using SMHs in tissue engineering?

Another promising direction is the programming and design of SMHs to better mimic biological environments by precisely modulating shape changes in vivo. Given that biological tissues possess self-healing abilities when subjected to specific thresholds, transferring these self-repair capabilities to smart polymers holds significant potential. Vascularization is also a critical challenge in tissue engineering using SMHs. Without proper vascular networks, tissues larger than a few microns can suffer from inadequate oxygen and nutrient supply, leading to necrosis. To address this, scaffolds must not only support cell growth and structural integrity but also promote capillary ingrowth. Embedding growth factors, prevascularizing networks within the hydrogels, or incorporating oxygen-generating agents or nanoparticles, such as calcium oxide, can help enhance oxygen supply and promote tissue regeneration.

Coronary artery bypass grafting (CABG) is the gold standard for treatment, traditionally relying on autologous blood vessels. However, graft availability is often limited by prior harvesting, donor-site complications, or disease progression, necessitating the use of alternative vascular grafts. An ideal vascular graft should be durable, biocompatible, non-toxic, non-immunogenic, and antithrombotic while supporting host tissue remodeling post-transplantation.

What remains a major challenge in SMH fabrication for medical use?

Unlike SMAs, which are rigid and primarily respond to temperature, SMHs offer greater flexibility and can undergo reversible shape changes in response to various external stimuli, including temperature, pH, ionic strength, and light. This adaptability, combined with their inherent hydrophilic and tunable mechanical properties, makes SMHs particularly well-suited for biomedical applications requiring soft, dynamic materials, such as tissue engineering, wound healing, and drug delivery [5]. A critical challenge in tissue engineering is the development of scaffolds that can conform to irregular tissue defects, adapt to changing physiological conditions, and enable minimally invasive implantation. SMHs address these challenges by temporarily deforming into compact shapes for easy insertion and subsequently recovering their original geometry in situ, ensuring precise spatial conformation and functional integration with surrounding tissues. Moreover, their responsiveness and tunable mechanical properties allow them to mimic the dynamic behavior of native tissues, making them ideal for self-fitting implants, dynamic cell culture systems, and responsive drug delivery platforms. By providing controlled shape recovery, biocompatibility, and enhanced tissue adaptability, SMHs represent a promising avenue for the development of next-generation biomedical scaffolds and therapeutic systems [6].

Why are biodegradable SMHs considered a sustainable option in tissue engineering?

Moreover, stimuli-responsive elements such as magnetic nanoparticles or graphene derivatives, while enhancing functionality, can pose immunotoxic risks due to bioaccumulation or ROS generation [187]. Patient-specific immune variability also complicates the standardization of scaffolds. Immunocompromised or elderly individuals may experience exaggerated or delayed inflammatory responses even with well-tolerated materials. Furthermore, long-term in vivo studies evaluating chronic exposure and late-stage degradation products are still lacking for most SMH systems.
