Participatory forest management has been globally studied and it has been argued that clearly defined boundaries for access of the community forest resources will lead to sustainable use of resources and enhanced sustainable livelihoods to the communities dependent on the forests for their survival. In contrast, however current studies indicate that while there are efforts to define spatial boundaries of resource use and the resource users within the community based forest management approaches, the definition of boundaries of resource use and resources users has proved more difficult, for instance when gathering relevant information and tools that can promote forest resource users partnerships,  engaging of different stakeholders, assisting local communities to organize, preparing for negotiations meetings, procedures, rules, logistics and equity considerations, negotiating for  the establishment of agreements and empowering  of the local communities. This book therefore provides a process that would guide the establishment of partnerships when establishing forest resources and resource users’ boundaries in order to enhance sustainable use of forest resources, mitigate conflicts and improve the livelihoods of communities depended on forests for their survival. Qualitative research design was employed in the book. All the forests involved in participatory forest management in Kenya namely: Keraite; Nyamweru, Arabuko-Sokoke Forest, Kakamega, Loita, and upper Imenti were selected for to provide information for writing the book. All the respondents were purposefully sampled from each category of interviewees namely: households living adjacent to the forest, various groups that are working in or with the communities in the management of the forest resources. Policy makers from government and a group of experts e.g. head of various government ministries and Non-Governmental organizations. To collect data semi-structured interviews were done for the respondents. All the data collected was analyzed through coding and grouping similar important ideas or phenomena from the research and then used for writing the book. It is explained in the book that functional partnerships, forest resources and resource user’s boundaries are needed for effective community participation in forest management. It is recommended that broad understanding of boundaries is a pre-requisite to ensure that community and other stakeholders appreciate resource use and the resource users within the community based forest management approaches so as to facilitate sustainable use of forest resources and enhanced community livelihoods of the forest dependent communities.

The National Natural Park Corales del Rosario y San Bernardo, located in the Caribbean Sea, is one of the most important parks in Colombia since it hosts high biological biodiversity, receives more tourists than any other natural park in the country and provides sustenance to several communities settled in and around it. However, lack of governance and incompatibility of incentives among authorities, communities and visitors threaten its conservation and sustainability. Using experimental economic games with fisherman communities, we tested different rules related with the management of natural resources in the protected area. In addition to standard rules of communication and external regulation, we tested a rule called co-management, in which we explored the complementarities between repeated communication and external non-coercive authority intervention. We also tested inter temporal effects where over extraction (by the group) in a round reduces the availability of resource for next round and, in consequence, increases effort and reduces benefits for fishers. Results confirmed the effectiveness of communication and, to some extent, external regulation. More important than that, co-management treatment exhibit no matter the location of the communities with respect to the park- the best results in terms of sustainable use of the resource. Participants incorporated dynamic implications in their decisions when information asymmetries were overcome, through internal communication or external guidance. These results highlight the importance of resource management designs that recognize communities as key actors in decision making for the sustainable use and conservation of common pool resources in protected areas.

The rapid population and industrial growth in Zimbabwe has resulted in land degradation and negative impacts on the human and physical environment. The primary purpose of this chapter was to find out the various indigenous environmental management practices available in Chimanimani that can be adopted by other communities in the conservation and sustainable use of resources. Secondly, the study explored Indigenous Knowledge (IK) and environmental management practices that can be integrated in the teaching of Geography in secondary schools, in order to ensure there is sustainable use of resources for the current and future generations. The study was guided by Edward Said (1978) post-colonial theory. An interpretive research paradigm was adopted in the community case study. Data were generated through a documentary analysis of the Form 1–4 (2015–2022) Geography syllabus, individual and group WhatsApp chats with Geography teachers and face-to-face interviews with community indigenous environment experts. The population sample consisted of ten (10) Geography teachers drawn from three (3) secondary schools and (6) community elders who were purposively sampled from the Chimanimani community. Data were analysed by generating thick descriptions and themes. The study revealed that the Chimanimani community has cultural practices that can be adopted in the conservation of resources. The research further exposed that IK related to environmental management can be integrated in the teaching of Geography in secondary schools in order to enhance sustainable use and environmental management of resources. The study recommends the integration of Indigenous and Eurocentric models in the conservation and sustainable management of resources. The incorporation of more indigenous environmental management practices in the Geography curriculum in secondary schools can help to inculcate a culture of environmental conservation among learners and communities.KeywordsIndigenous Knowledge (IK)IntegrationEnvironmental ManagementChimanimani communityGeographySustainable

South African National Parks (SANParks) has a history of formal and informal natural resource use that is characterised by polarised views on national conservation interests and benefits to communities. Current efforts aim to determine the sustainability of existing resource use in parks and to formalise these activities through the development of resource use protocols. The resource use policy of SANParks outlines principles for sustainable resource use, including greater involvement of local communities in management of protected areas and an adaptive management approach to determining sustainable use levels. This paper examines three case studies on plant use in national parks with regard to the development of criteria and indicators for monitoring resource use, and the role of thresholds of potential concern in measuring effectiveness of managing for sustainable use levels. Opportunities and challenges for resource use management are identified. Findings show that platforms for discussion and knowledge sharing, including research committees and community associations, are critical to building relationships, trust and a shared vision of sustainable resource use between stakeholders. However, additional capacity building is needed to enable local community structures to manage internal social conflicts and jealousy, and to participate fully in monitoring efforts. Long-term monitoring is essential for developing flexible harvest prescriptions for plant use, but this is a time-consuming and resource-intensive exercise. Flexible management strategies are difficult to implement and sometimes command-and-control measures are necessary to protect rare or endangered species. A holistic approach that considers resource use in national parks as a complement to broader community development initiatives offers a way forward. Conservation implications: There is no blueprint for the development of sustainable resource use systems and resource use is often addressed according to multiple approaches in national parks. However, the SANParks resource use policy provides a necessary set of guiding principles for resource use management across the national park system that allows for monitoring progress.

The topic of a sustainable use of natural resources, often understood as resource efficiency, has made its way up on the political agenda. But so far a fundamental change towards a sustainable use of resources has not been achieved. Not only the resource consumption is still growing and destroying more and more the ecosystems but also too often the exploitation of natural resources is still a story of violation of human rights and of intra- and intergenerational unfairness. This chapter describes in a first step the current resource policy landscape, then identifies challenges on the way to further progress and finally outlines next steps for addressing the challenges of the management of natural resources in the context of sustainable development. The analysis of the resource policy landscape shows three clusters of resource policies. The more operational the approaches are the more they are neglecting the inter-linkages amongst the various natural resources and/or the general requirements of sustainability. The challenge is to broaden the perspective of these more implementation oriented resource efficiency concepts into approaches which manage natural resources within a framework of sufficiency, fairness and responsibility, consistency and resilience. Important steps are seen in deeply rooting these principles into the public and private sector, in changing the institutional settings towards a more sustainable resource management. But also in a more systemic thinking, which addresses the nexus of the various resources and in implementing sustainable resource use in the civil society as a practice of daily life.

A global indicator of utilized wildlife populations: Regional trends and the impact of management

This study analyses the extent and spatial distribution of the forest resources and their energy potential in the province of Nuoro (Sardinia, Italy). The aim is to create a data base which will help decision makers to make a plan for the sustainable use of the resources of the territory. A GIS-based model was used to assess the energy capacity and suitability of the area. This model used four basic information layers: (1) slope, (2) hydro-geological constraints, (3) protected areas, (4) forest districts under regional forest management. These four criteria are of great importance when attempting to assess the quantity of available sustainable biomass. Based on their potential energy production, 140 basins were identified, which could provide enough forest biomass to fuel all the heating systems currently installed in public buildings of the Provincial administration.

Sustainable development is an important topic of urban research. The rational use of land resources is of great significance for urban development and is conducive to promoting regional governance and coordinated development. The purpose of this study was to construct an effective evaluation framework for urban land resources to maintain sustainable urban development. Taking the cities along the Jiangsu Section of the Beijing–Hangzhou Grand Canal as the research object, this study constructed an evaluation system for the sustainable use of land resources including the dimensions of economic level, social development, and environmental resources. The statistical data for 2010, 2015, and 2020 were selected to comprehensively calculate and evaluate the level of sustainable use of land resources in the study area via the analytic hierarchy process (AHP)-entropy combined weight method, which combines the analytic hierarchy process and the entropy weight method. According to the research results, the sustainable use of land resources in the study area presented an overall upward trend from 2010 to 2015, and an overall downward trend from 2015 to 2020. Overall, the study area was in a critically sustainable stage, although the annual change rate of the level of sustainable use of land resources showed significant fluctuations and exhibited a spatial pattern of progressive increase from north to south. The cities in southern Jiangsu were in the initially sustainable and basically sustainable stages; those in central Jiangsu were in the critically sustainable and initially sustainable stages; and those in northern Jiangsu were in the unsustainable and critically sustainable stages. This study proposed a scientific and effective evaluation method for cities along the Grand Canal to explore the efficient, sustainable use of land resources in the future. The evaluation framework constructed on this basis can serve as an important reference for urban governance and is expected to guide the sustainable use and development of land resources for other cities of the same type.

Wood resources for energy sector in Latvia. Is it a sustainable solution?

Blue economy is an economic system or sector that seeks to conserve marine and freshwater environments while using them in a sustainable way to develop economic growth and produce resources such as energy and food. In terms of the global economy, around 90 per cent of all internationally traded goods are shipped by sea, and the market value of marine and coastal resources and industries is estimated at US$3 trillion per year or about 5 per cent of global gross domestic product. Sustainable use of ocean, seas and marine resources, as set out in SDG14, lies at the center of a sustainable blue economy. Sri Lanka‘s coastline is 1,340 kilometres and approximately 33 percent of Sri Lanka's population lives in coastal areas that support diverse livelihoods, from fishing to tourism to manufacturing and modern urban services. The coastal areas often provide excellent soil and climatic conditions for agriculture, which has been practiced for thousands of years and plays an important role in the economy of coastal areas. Apart from the traditional rice based farming systems it also comprise of coastal fishing and coastal aquaculture, seaweed cultivation, coconut based cropping systems, commercial cash cropping systems and homestead farming systems. With regards to forests, mangroves, coastal forests, savannah woodlands, dry forests are present in these areas. Further, coral reefs, sea grass beds, salt marshes also play an important role in sustaining the balance as together they provide habitats for biodiversity, food, shade, medicine, products for the industry, protection of the coastline and carbon sequestration. However, these ecosystems are threatened due to numerous factors; climate change (as it induces flooding, shoreline erosion, salinity intrusion, temperature rise), due to conflicting activities such as operational in these coastal areas such as infrastructure including shoreline structures (harbors, breakwaters, tourist hotels), other tourism activities, industry etc. On the face of this, these ecosystems are often in the frontline to get depleted. The habitats are also getting modified due to the increase of toxicity from both inland and marine pollution, invasion of species. Therefore more concerted effort need to be exerted for the conservation and sustainable use of the oceans, seas and marine resources if the country wants to reap the benefits of the blue economy sustainably. As oceans are shared by many countries, actions need to be taken at country, region and even global levels in the areas of regulation, technology transfer, enhancing awareness and education. A mechanism for regular monitoring is a must and this responsibility need to be shared by all the stakeholders. It is imperative to zone the coastal areas so that complementary activities will be lumped together. It is also required to strengthen the already available international agreements between the member countries such as South Asian Seas Programme, Programmes with the International Maritime Organisations, IORA (Indian Ocean Rim Association), BIMSTECH in arriving at regional policies and action plans and implementation of same with proper monitoring. The quantification of the resource is a vital step. It is also important to operationalize the Coastal Zone Management Plans in existence and declare Special Area Management Sites to ensure conservation and sustainable use of these resources.

This study reports the effects of single-point incremental forming (SPIF) process variables like vertical step down (0.2, 0.4, 0.6 mm), tool diameter (6, 8, 10 mm), feed rate (300, 600, 900 mm/min), spindle speed (300, 450, 600 rpm), lubricant (dry, oil, grease) and sheet thickness (0.6, 0.8, 1.0 mm) on the formability of Monel 400. Based on the varying wall angle tests conducted, it was found that the vertical step down was the parameter most influential in achieving maximum wall angle. The forming limit diagram constructed with the data obtained from straight groove tests revealed the parameter combination for low, moderate, and high formability while forming along different directions (0°, 45°, 90°). Also, it was observed that the formability has been positively influenced by increased tool diameter in the case of 0° orientation, spindle speed in the case of 45° orientation, and vertical step down in the case of 90° orientation. Based on the fractography study, it is concluded that more number of voids enhanced the forming limit. This may be due to the coalescence of voids and their slow aggregation. Based on the combined grey relational analysis and principal component analysis, it is obtained that the order of influencing parameters is vertical step down, tool diameter, sheet thickness, spindle speed, lubricant, and feed rate for obtaining the maximum sum of strains (0°, 45° 90°) and maximum wall angle.
