Immediately after the adoption of the Sustainable Development Goals (SDGs), the Parties to the United Nations Convention to Combat Desertification (UNCCD) requested the Science-Policy Interface of the UNCCD (UNCCD-SPI) to develop a Conceptual Framework for Land Degradation Neutrality (LDN) to aid countries in their target-setting programmes for LDN and in the concrete implementation of LDN interventions. Based on these concrete policy requests, the Conceptual Framework for LDN was developed by a multi-disciplinary team of scientists and science-policy officers, and endorsed by the Parties to the UNCCD in September 2017.

The principles of the LDN conceptual framework (See "Land in balance: The scientific conceptual framework for Land Degradation Neutrality" Environmental Science & Policy, Volume 79, Pages 25-35) are core to this special issue, and provide a basis for critical discussions from a broad range of disciplinary, stakeholders’ and regional perspectives on past, existing, and emerging challenges for policies and strategies to implement LDN, in tandem highlighting opportunities for transformative socio-economic processes and ethical aspects emerging from policies and processes to achieve LDN. The papers aim to support national sustainable development aspirations by providing guidance of needed policies, procedures and governance to regulate national land use by avoiding further net loss of productive lands.

Experts invited to contribute to this special issue will address policy principles, rules, guidelines and procedures to design national actions that contribute to LDN implementation, discuss tools and approaches to track and evaluate the implementation process, including substantive discussion on evidence-based policy successes and failures. As well indicator systems and metrics to monitor the achieved and nationally desired status of the land are relevant to this special issue. Contributions could also focus on targeted framing of future policy-oriented research, and technology to achieve and to maintain LDN, identifying key human, technical and institutional capacity needs at national and sub-national levels. The special issue intends to be a true guide for LDN, providing both the scientific foundation and a pathway for implementation.

The special issue intends to be a true guide for Land Degradation Neutrality, providing both the scientific foundation and a pathway for implementation. LDN is at the core of the UNCCD strategic framework and the Sustainable Development Goal target 15.3. The papers will therefore target one or more of the following questions:

- How does LDN contribute to national sustainable development?

- What synergistic effects emerge for achieving the SDGs through the implementation of LDN?

- How can LDN be mainstreamed across sectors and stakeholders for achieving sustainable development?

- What type of practical frameworks, policies, procedures and guidance are required at country level?

- What issues need to be targeted in order to prevent net loss through regulated land use?

- What are the socio-economic, ethical and policy impacts of pursuing LDN?

- Methods and approaches to mainstream LDN at national level, instruments for implementation, and indicator systems for target setting LDN and for tracking progress, including monitoring.

Considering the great variations in chemical structures of bioactive compounds (BACs) that are valuable for human health and large number of herbal sources with variation concerning the anatomy, e.g. leaves, stem, flower and fruits, it is necessary to build up a standard and integrated extraction and analytical approaches to obtain and screen these compounds. More so, as the interest for the use of such BACs in different products in pharmaceutical, food and chemical sectors is constantly rising and signifies the need for identifying the most appropriate and standard extraction technique of bioactive molecules from the natural sources. Along with conventional methods (CE), numerous new innovative methods have been established, but until today, there is an ongoing debate dealing with selection of the best choice. The most of CEs are based on the extracting power of different organic solvents combined with heat and/or mixing. Current consensus is that extraction efficiency of any CE mainly depends on the right choice of solvents and polarity of target compounds. More so, molecular affinity between solvent and solute, mass transfer, the use of co-solvent, environmental safety, human toxicity, and financial feasibility are general limitations for the use of solvents. However, alternative approaches to CE emerged in attempt to mitigate abovementioned limitations, such as Microwave assisted extraction (MAE), Ultrasound-assisted extraction (UAE), Pulsed-electric field extraction (PEF), Enzyme-assisted extraction (EAE), Pressurized liquid extraction (PLE), Supercritical fluid extraction (SFE), Rapid Solid-Liquid Dynamic Extraction (RSLDE) to name a few. Therefore, the main purpose of this Special Issue in Food Research International journal is to collect and publish innovative works on extraction techniques that can improve the knowledge on the isolation of BACs from plant matrices for human nutrition. The papers submitted for consideration for publication in this special issue, must bring novel information and must be supported by appropriate state-of-the-art methods of characterization of bioactive compounds. Pure optimization papers will not be accepted.

In view of the above potential and developments, Food Research International is inviting authors to submit unpublished original contributions, critical review articles and short communications for consideration in the special issue “Conventional, non-conventional extraction techniques and new strategies for the recovery of bioactive compounds from plant material for human nutrition”. Topics covered in this special issue include but are not limited to:

- Comparative evaluation of different extraction methods

- Development of new technologies for the extraction of bioactives

- Supercritical fluid extraction

- Enzyme assisted extraction to improve the recovery of bioactives

- High-pressure technology for extraction of bioactives

- Electrotechnologies

- Ultrasound and microwaves

- Extraction of bound/coniugated bioactives

- Evaluation of the impact of conventional and innovative extractions on nutritional and bioactive characteristics of recovered products

- Applications and commercial perspectives of new techniques

- Scale-up and implementation of innovative extraction techniques

The contributions of this volume aim to increase conceptual and empirical understanding of societal and environmental challenges, opportunities, trade-offs and the transition to a circular bioeconomy in the forest sector. Despite hosting a high degree of internal diversity, the circular and bioeconomy are distinct concepts employed to forward sustainability, and in particular to reconcile economic and environmental goals.

The circular economy has historical roots in the 1970’s ideas of industrial ecology and metabolism, and contemplates a rethinking of industrial processes and product life cycle towards a minimization of input and waste through reduction, efficiency, recycling and reusing (Korhonen et al. 2018; Martins, 2016; The Ellen MacArthur Foundation, 2012). The bioeconomy advocates for industrial inputs (e.g. material, chemicals, energy) to be substituted by or complemented with renewable biological resources (Hausknost et al., 2017; Priefer et al., 2017; Pülzl et al., 2014). The primary productive sectors (forestry, agriculture and fisheries) play a fundamental role in providing such resources, with research and innovation enabling such transformation (Ollikainen, 2014; Roos and Stendahl, 2016). Several scholars have started to advocate for a circular bioeconomy, which implies a parsimonious use of bio-based resources (e.g. Antikainen et al., 2017; Venkata Mohan et al., 2016). In the context of the forest sector, an example of circular bioeconomy includes the principle of cascading use of wood (Bezama, 2016; Ciccarese et al., 2014; Vis et al., 2016).

As de Besi and McCormick (2015, p. 10462) argue, “…transition described for the bioeconomy and post-carbon strategies and pathways will require system-wide changes involving society, governments and industry”. However, the scientific debate about what sustainability in the context of circular bioeconomy really means is still at an early stage. In a review, D’Amato et al. (2017) called for “refining, clarifying and systematizing contemporary concepts of circular, green and bioeconomy” and promoting the more integrated interpretation and applications of these as a way to enhance effectiveness towards common sustainability goals. This requires also identification of opportunity areas and related societal actors to pursue the merging of multiple concepts in light of their synergies and conflicts.

Enhancing renewal of the smart and sustainable business plays a vital in order to create sustainability leadership, calling strategic insight to secure competitiveness and consumer acceptance of new bioeconomy products and services in the international markets. Essentially, maintaining high environmental, social and economic sustainability of the forest-based sector is linked to both forces of globalization and competition between world regions, as well as the ability of the private sector to commercialize the potential of innovations related to the bioeoconomy. New products and services are needed, but also mature industries can be transformed by new strategies and technologies (Näyhä et al. 2014). A circular forest bioeconomy requires both structural and functional changes in both production and consumption happening at multiple levels (including sectoral, industry, market, or consumer). Sectoral boundaries are blurring in the bioeconomy via policy drivers and substitution effects in the markets, and new forms of competition and co-operation emerge between established and new business actors from, e.g, forest, chemical, food, biotechnical and construction sectors. Stimulating sectoral transition is keenly associated with maintaining sustainability by increasing efficiency in material and energy use towards zero-waste production and facilitating structural industry adaptation that produces the much needed radical innovations to allow market growth.

The main topics of intended submissions can be related to the following questions:

- Which interlinkages across a range of renewable and non-renewable resource-based business activities within society are of most strategic importance? How to promote their development to foster growth and competitiveness of forest-based circular bioeconomy?

- How do business network structures and sustainable business models orchestrate the sustained change towards forest-based circular bioeconomy?

- What are the key policy means to overcome the potential obstacles and trade-offs and to reach transition towards sustainable forest-based circular bioeconomy? In particular, how are circular and bioeconomy policies and strategies aligned (or if not) together?

- What are the possible future developmental pathways and the related bottlenecks that may influence to the development of forest-based bioeconomy?

On behalf of the editorial team, we invite contributions to a Special Issue of Environmental Science and Policy, entitled Knowledge Systems for Urban Resilience.

Cities are on the leading edge of climate change adaptation and resilience (Meerow, Newell and Stults 2016), implementing more efficient transportation, building technologies, and green infrastructure, among other improvements. Yet, as the historic 2017 hurricane season has shown, the practices that guide urban planning and development must be transformed in order to address a new reality of more intense climate events. This transformative innovation is fundamentally tied to how societies organize knowledge (Matson 2009; Redman and Kinzig 2003), enabling institutions to learn, innovate, and adapt (Ernstonet al2010; Fink 2011). From building codes and standards, to the ways that flood maps are drawn and risk is communicated to the public, urban societies use certain kinds of knowledge to ‘think’ (Muñoz-Ericksonet al2017)--yet much of it is currently based on historical climate data, which is limited in its ability to address the new environmental conditions of climate change.

In this special issue, we invite contributions that explore how changing the social practices and institutions that produce, validate, circulate, and use information, data, and expertise -- what has been termedknowledge systems(Milleret al2010) -- is fundamental to how urban societies build resilience and anticipatory/adaptive capacity for the unpredictable and highly dynamic conditions of the Anthropocene. The ability to link knowledge to action is not simply a problem of an adequate supply of scientific knowledge (Sarewitz and Pielke, Jr. 2007), but rather requires a rich understanding of the social and institutional context in which knowledge is generated and how it frames decision-making (Viguié and Hallegatte 2012). While studies have suggested that climate change adaptation will require dynamic sets of knowledge types—scientific, technical, local, and tacit—about complex, interconnected problems across spatial and temporal scales (Nursey-Brayet al2014; Frantzeskakiet al2016; Jasanoff 2010; Hulme 2010), less attention has been directed to how these different ways of knowing might be used to transform specific urban knowledge systems that are currently in place, to align with diverse societal needs, and open new pathways for (re)designing how city systems sense, anticipate, adapt to, and learn from extreme weather events (Leachet al2010; Milleret al2018).

We are particularly interested in work that addresses one or more of the following questions through either new conceptual formulations or case-study approaches, including qualitative, quantitative, and mixed methods:

- What are the knowledge practices -- such as reflexivity, co-production, and adaptive co-management -- for building anticipatory capacity, and how do they help cities cope, prepare for, and thrive in a new climate?

- How do/could the roles of different players -- such as urban planners and municipal managers, community organizers and activists, as well as ecologists, global environmental change scholars, emergency management professionals, data scientists, and engineers, among others -- contribute to changing the knowledge practices of their own institutional affiliations, to better meet a range of needs in relation to climate change?

- What are the tensions between transforming and reproducing dominant knowledge practices, and how might these help cities become more resilient?

- What metrics are there for assessing how effectively knowledge is used in urban climate adaptation and mitigation?

- What are the key institutional, social, and political transformations needed to better align knowledge production with building resilience to a dynamic and uncertain climate future?

- How can an understanding of the social and institutional contexts that frame decision-making help identify strategic intervention points in making urban infrastructure more resilient?

- How can upgrading knowledge systems help translate advances in fundamental knowledge about climate and atmospheric dynamics into substantive actions to improve adaptation to emerging climate threats?

From the origin of life on the earth, plants are experiencing the several impacts of changing environment and thus adopted several strategies for their survival. These environmental changing conditions somewhere caused very serious abiotic and biotic stress conditions for the plants which ultimately caused serious damages to plant metabolic system and ultimately caused plant death. During these stress conditions plants expresses several indications of their troubles and produce the increased levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cells which have been advertised as the toxic and harmful for the plants till date. However, it has also well discussed that at low concentrations, ROS and RNS can perform as signals for the regulation of growth and development and for the defense of plants against the both biotic and abiotic stresses. It cannot be ignored the involvement of these two (ROS & RNS) in almost every facet of plant metabolism and cell functions. Recent updated knowledge about the effects of reactive oxygen species (ROS) on plants have turned ROS from being considered a harmful substance into a beneficial, since their roles have been exposed in numerous plant developmental processes as signaling molecules. In addition, over last few decades, nitric oxide (NO) has also come into view as a vital participant in redox signaling. Current reports offered a very clear fact that RNS especially NO and ROS impacted each other’s biosynthesis and removal. In addition, there are several new signaling molecules including N2O3, ONOO-, NO2, S-nitrosoglutathione and 8-NO2cGMP have been reported as a results from the chemical reaction between NO, ROS and plant metabolites. These new signaling molecules are tightly involved in various plant physiological and metabolic processes and provide direct and indirect benefits. Thus, the evidences exhibit the multifarious communications among of these two i.e. RNS, ROS signaling and the antioxidant system, although detail and deep exploration are required to present a global understanding of this coordination.

Hence, this especial issue for Environmental and experimental Botany is aimed to spoke the following key questions connected to the interplay among RNS signaling, ROS and their major consequences on plant physiology, biochemistry, molecular biology etc.

- An updated over view of ROS and RNS in plant biology

- ROS and RNS signalling networks in plants

- Universal targets and receptors

- Interface of RNS and ROS signaling among redox-active proteins

- Detection of novel RNS- and ROS-consequential redox signals

- Comprehensive depiction of redox signal cascades and networks

- Regulation of ROS homeostasis by NO and vice versa
