Tourism potential of Dombe Grande, Ba穩a Farta, Benguela in Angola
The municipality of Dombe Grande has valuable natural, historical, monumental and cultural tourism resources that need to be properly identified, classified and systematized for subsequent strategic planning. From this perspective, tourism can become one of the main strategic axes for local development and play an important role in the process of diversifying the local economy, as tourism in the town can perfectly complement the predominant agricultural sector in the area. This proposal aims to make the most of the attractive resources identified. We want to bring to the attention of readers the rich culture: traditions, habits, customs and mystique of the Mundombe people, located in the Dombe Grande commune, Benguela province, so that all this heritage (tourist attractions) can be placed in the tourism network of Angola, Africa and internationally.
From Blasting to Grinding
Comminution is an essential part of mineral processing which involves the breakage of ore to achieve size reduction. Its aim is to increase the likelihood of separation and liberation of valuable minerals from gangue in subsequent processing stages (Napier-Munn et al., 1996; Fuerstenau, 2003; Wills and Napier-Munn, 2015). Ore breakage in comminution occurs in three forms, namely; blasting, crushing and grinding (Kapur et al., 1997; Le Pham, 2011; Yahyaei et al., 2016). During blasting, ore breakage occurs by means of explosive devices. In crushing, it occurs via mechanical compression of ore against hard surfaces (Unland and Szczelina, 2004). In the case of grinding, ore breakage takes places through a combination of two or more of: impact (ores drop against a rigid body or media drop against ores), abrasion (ores of similar size shear against each other) and attrition (relatively big ores grind smaller materials) (Austin, 2002; Le Pham, 2011; Wills and Napier-Munn, 2015). Comminution is well known to be highly energy-intensive. Previous studies have shown that comminution typically accounts for 50% of the energy consumption in a mineral processing circuit, and globally comminution activity accounts for about 0.2% of the world's electricity supply (Napier-Munn et al., 1999; Ballantyne and Powell, 2014). In addition, the process has been shown to be inefficient, in that a small fraction of the energy supplied is directly utilised for rock breakage (Tromas, 2008). The remaining energy is either lost as heat (Radziszewski, 2013), carbon dioxide (CO2) emissions (Norgate and Haque, 2010) or absorbed by the comminution equipment causing wear and degradation (Weerasekara et al., 2013).

Report on the water quality monitoring network in 2023
This report highlights the crucial importance of monitoring water quality in Burkina Faso, due to multiple sources of pollution such as industrial discharges, artisanal mining and the intensive use of chemical fertilizers in agriculture. These factors compromise the physico-chemical quality of the water, making it unsuitable for a variety of uses. Since 1992, a national water quality monitoring network, initially consisting of 32 points, has been in place, but has proved insufficient in the face of increasing pollution. In 2018, an expansion of the network to 80 sites was undertaken, but security constraints have prevented some points from being monitored in 2023. The report highlights the difficulties associated with data collection, processing and use, while identifying the needs to ensure adequate monitoring of raw water quality at national as well as cross-border level.

Making Nature Social
As the global climate crisis and biodiversity loss deepen their impact and gain pace, Making Nature Social: Towards a Relationship with Nature provides core insights into what it means to understand our relationship to nature. This relationship is illustrated through interviews with people working in different nature practices, including engaging with nature, non-human animals, place, advocacy, and with work organization values. Rembrandt Zegers argues that since non-humans do not use human language, meaning is conducted through the senses, giving rise to a knowing that manifests itself through the body first before finding its way socially in human language. Through these senses the relation to non-human others and nature can become a conversation; in other words, a relationship built on reciprocity. The book illustrates how these meanings occur and how these conversations happen, how crucial they are, and how they are connected. It dives deep into the essence of the lived experience of our relationship to nature and in doing so acknowledges how important the lived experience is for the purpose of a relationship with nature.
Deep Water
"Deep Water is a major achievement....Bradley's skills both as novelist and essayist converge here to create this wise, compassionate and urgent book, characterized throughout by a clarity of prose and a bracing moral gaze that searches water, self and reader." --ROBERT MACFARLANE, bestselling author of UnderlandIn this thrilling work--a blend of history, science, nature writing, and environmentalism--acclaimed writer James Bradley plunges into the unknown to explore the deepest recesses of the natural world.Seventy-one percent of the earth's surface is ocean. These waters created, shaped, and continue to sustain not just human life, but all life on Planet Earth, and perhaps beyond it. They serve as the stage for our cultural history--driving human development from evolution through exploration, colonialism, and the modern era of global leisure and trade. They are also the harbingers of the future--much of life on Earth cannot survive if sea levels are too low or too high, temperatures too cold or too warm. Our oceans are vast spaces of immense wonder and beauty, and our relationship to them is innate and awe inspired.Deep Water is both a lyrically written personal meditation and an intriguing wide-ranging reported epic that reckons with our complex connection to the seas. It is a story shaped by tidal movements and deep currents, lit by the insights of philosophers, scientists, artists and other great minds. Bradley takes readers from the atomic creation of the oceans, to the wonders within, such as fish migrations guided by electromagnetic sensing. He describes the impacts of human population shifts by boat and speaks directly and uncompromisingly to the environmental catastrophe that is already impacting our lives. It is also a celebration of the ocean's glories and the extraordinary efforts of the scientists and researchers who are unlocking its secrets. These myriad strands are woven together into a tapestry of life that captures not only our relationship with the planet, but our past, and perhaps most importantly, what lies ahead for us.A brilliant blend of Robert MacFarlane's Underland, Susan Casey's The Underworld, and Simon Winchester's Pacific and The Atlantic, Deep Water taps into the essence of our planet and who we are.

"Beyond Soft Shores" aptly highlights the need to bridge this knowledge gap. By delving deeper, we can understand how water interacts with the distinct geology of bedrock estuaries, influencing everything from nutrient cycling to resident species. This knowledge is crucial for protecting these vital ecosystems, often overlooked due to a lack of data. Filling the gap on bedrock estuaries isn't just about rocks; it's about safeguarding a unique and vital part of our ocean's heart
Sustainable Agriculture
The progress of science and technology and intensive land usage have promoted the rapid development of modern agriculture. Meanwhile, however, modern agriculture has caused global ecological and environmental problems due to its consumption of large amounts of resources and energy. To meet these challenges, we must rethink the theories, policies, models, and technologies involved in modern agricultural development, which includes new concepts and methods of agriculture: for example, organic agriculture, compound agriculture, circular agriculture, and ecological agriculture. There is a growing awareness that the development of sustainable agriculture should not only increase yields to meet people's demands, but also should improve product quality and promote multi-functioning of the agricultural ecosystem. Although the study and practices of sustainable agriculture have achieved remarkable results in the past 40 years, the development of the social economy and current challenges of world agriculture require significant consideration for the future of agriculture. Summarizing available knowledge and lessons, analyzing associated problems, and mapping out future developments will help in promoting the practice and policy of sustainable agriculture, as well as in innovating sustainable agricultural theory and methods. This reprint includes 16 articles that focus on theoretical methods, policies, and practical experience related to sustainable agricultural development, aiming to contribute to the sustainable development of agriculture and food security.

Impacts of Land Use Pattern in Metropolitan Area
Owing to the increased associations between land use patterns and economic, social, and environmental systems in metropolitan areas, the exploration of the impacts of land use is of great importance for more efficient land use in spatial planning and policy-making. This reprint contains mainly empirical studies focusing on the effects of land use attributes on a series of socioeconomic and environmental indicators, such as gross domestic product, entrepreneurship, housing prices, street-level pedestrian volume, carbon storage and emission, and microplastic concentrations. New data such as mobile phone signaling data and new approaches such as spatial interaction modeling are applied in the studies included in this reprint to describe land use patterns and the impacts of land use.
CO2 Capture and Sequestration
CO2 capture and sequestration (CCS) technologies aim to capture carbon dioxide (CO2) from CO2 sources, separate the CO2, and store it in suitable media. CO2 can be captured using various technologies, including absorption, adsorption, cryogenic processes, and membrane gas separation. Therefore, accurate selection, design, modelling, and optimisation of the processes for CO2 capture and the tuning of the material properties are essential. There are different methods used for CO2 sequestration, e.g., (i) geological sequestration, which injects different phases of CO2 into the subsurface; (ii) oceanic storage, which dissolves CO2 into an ocean at different depths; (iii) the solid-phase reaction of CO2 with metal oxides to produce stable carbonates with no risk of CO2 release to the atmosphere; etc. The flow, transport, and reaction of CO2 during CCS and other related matters are also essential. To address these points, a Special Issue of Clean Technol.and a reprint with all published papers have been organized which highlight the recent trends and innovative developments in CCS. In particular, these papers highlight the following issues: Socio-political issues related to CCS development and deployment; Fundamental technical issues concerning the development and deployment of CCS; The synthesis of value-added chemicals using captured CO2 in CCS; Applications of mathematical modelling for the development of CCS. The development of techno-economic costing models for CCS. Overall, this reprint covers a diverse range of topics, including some of the most pressing concerns for the future growth and development of CCS.

The Bible and Sustainability
The Bible and Sustainability addresses the ecological crisis the world is facing, and what the Bible can teach us about sustainable living. Drawing on the interest in the ecological debate generated by Laudato Si, this book attempts to push the discussion beyond intellectual perspectives and help students and researchers apply biblical wisdom to the UN sustainable development goals.It begins with a discussion of what sustainability is, and how people, planet, and profit are affected by unsustainable practices, before exploring four specific biblical practices and their relationship with sustainability: Covenants, the sabbatical year, monastic communities, and the fruit of the spirit. It also discusses the creation account and personalistic nature texts, considering the social relationship that humans have with nature. Finally, it examines an Augustinian perspective on sustainability which encourages sharing, common ownership of property, and living simply. The book concludes by inviting governments, civil society organizations, and academia to bring these biblical practices and passages into the ecological debate.It is an outstanding resource for researchers of the Bible and environment, and Religion and environment more generally.

The fundamentals of national park tourism and the potential as an economic engine
Seminar paper from the year 2024 in the subject Geography / Earth Science - Tourism Geography, grade: 1,3, University of Applied Sciences Wernigerode (International Tourism Studies), course: International Tourism, language: English, abstract: The tourism industry was one of the fastest-expanding economic sectors before the coronavirus and continues to maintain its status as the world's dominant service industry. "(...) in 2019 alone, over 1.5 billion tourist arrivals were registered (...) with a growing importance of domestic tourism." The interdependence between the increase in travel and the economic importance of tourism has been proven. Looking at the situation before the virus, it can be seen that the tourism industry contributed over 10% to global economic output. Furthermore, over 230 million jobs depend on tourism, which accounts for around 9% of global employment. As a result, it is no secret that the tourism industry is a highly profitable source of income and has the ability to combat poverty and stimulate the regional economy. The latter will be examined in more detail in the next section in order to create essential foundations for the further course of the work. Since the focus of this work is on the United States, the aim is to provide a brief insight into the American tourism industry. When evaluating the overall economic production value of the tourism sector, the World Travel & Tourism Council was able to determine that the USA occupied first place by a significant margin in 2007 and was able to maintain this position 10 years later with an increase of 44.94 % . But when it comes to travel spending, Americans also took first place in 2005 with a total of around 82 billion dollars, and they took relatively significantly more trips within their home country. The reason for this lies primarily in the richness of the diverse climate zones and landscapes.
Asteroid Belt History and Terrestrial Bombardment
The main asteroid belt, spanning approximately 2-4 AU in heliocentric distance, serves as a sparse repository of rocky debris, offering invaluable insights into the solar system's past. Evidence drawn from the dynamical structure of both the main belt and the Kuiper belt beyond Neptune suggests a narrative of planetary migration, wherein the giant planets initially existed in a more compact formation before experiencing migration driven by planetesimals. This migration event swept both mean motion and secular resonances across the main asteroid belt, inducing a rise in asteroid eccentricity and depletion of the belt itself. Examination of present-day distributions of large main belt asteroids aligns with this narrative, offering further support for resonance sweeping during the epoch of giant planet migration. Utilizing an analytical model of ν6 secular resonance sweeping, constraints on Saturn's migration speed can be inferred. Post-migration, dynamical chaos emerged as the primary loss mechanism for asteroids with diameters exceeding 10 km, with a logarithmic decay law effectively describing the dynamical loss history of test particles from this region. This model implies a potential decline in the rate of impacts from large asteroids over the last approximately 3 billion years, suggesting a present-day impact flux significantly lower than previously estimated, impacting crater chronologies and hazard risk assessments. Additionally, quantification of the solar wind's 6Li/7Li ratio reflects the influx of chondritic material and enhanced dust production during planetesimal-driven giant planet migration, contributing to the current depletion of lithium in the solar photosphere relative to chondrites. The expectation of 6Li being less abundant in the sun compared to 7Li due to differing nuclear reaction rates further supports this narrative. Furthermore, evidence pointing to a short-lived impact cataclysm affecting the entire inner solar system may be discernible in t
Climate Perspectives from the Congo Basin
This book considers the global question of climate change from local perspectives in the context of Central Africa.Bila-Isia Inogwabini examines attempts made by the international community to respond to the global challenges posed by climate change in the Congo Basin and highlights that these attempts have so far produced limited results. Abject poverty and the lack of academic, technical, institutional and governance capacities have made it difficult for these solutions to take root in local conditions. Taking a novel perspective, Inogwabini argues that what is needed is not austerity in the use of natural resources but rather increased material affluence for these communities, which will enable individuals to create their own ways to survive through the tides of climate change. He considers factors including social inertia, climate skepticism and lack of political structure and presents a climate change action plan that is targeted at the local level in the Congo Basin.Overall, this volume will be of great interest to students and scholars of climate change, global development and African studies more broadly.

Stagtine
"If you think you understand regenerative agriculture, think again. Firth's experience and writing challenges all pre-conceived notions and helps us rethink our relationship to nature around us and the earth beneath our feet." - Hilda Labrada Gore, Wise Traditions Podcast of the Weston A. Price Foundation.Are Homo sapiens mammals or mini gods?Stagtine is an epic tale, rich with science and agricultural insight, of one family's transition from a struggling regenerative farm to a pioneering kincentric rewilding landscape.Our modern mythology is the climate crisis. From mass species extinctions that tally at pace with exhaled breath to the reigning of carbon and pollution that suffocate our scorching days-she is knocking, and she is at the door. We are told that we need to do more: do more to save the world, do more to build efficient, regenerative systems. We are told agriculture is here to save the day. But will it be enough?What if that was the wrong question? What if climate change is not a crisis to be solved but a living force inviting us back into relation?In Stagtine, Griffith illuminates the gauntlet that is modern life and agriculture, industrial or regenerative, and rather than telling us how to run the race, he suggests that we step back, turn within, and look to all relations for guidance on how to inform our next steps.Rather than the modern story that humans must "save the world," Stagtine circles inward to a simpler, more ancient proposal: we can enliven our visit to Earth by relinquishing control and stepping into right relationship with one another and the landscapes we inhabit.Foreword by Dr. Fred Provenza.
The Great River
The Mississippi River lies at the heart of America, an undeniable life force that is intertwined with the nation's culture and history. Its watershed spans almost half the country, Mark Twain's travels on the river inspired our first national literature, and jazz and blues were born in its floodplains and carried upstream.In this landmark work of natural history, Boyce Upholt tells the epic story of this wild and unruly river, and the centuries of efforts to control it. Over thousands of years, the Mississippi watershed was home to millions of Indigenous people who regarded "the great river" with awe and respect, adorning its banks with astonishing spiritual earthworks. The river was ever-changing, and Indigenous tribes embraced and even depended on its regular flooding. But the expanse of the watershed and the rich soils of its floodplain lured European settlers and American pioneers, who had a different vision: the river was a foe to conquer.Centuries of human attempts to own, contain, and rework the Mississippi River, from Thomas Jefferson's expansionist land hunger through today's era of environmental concern, have now transformed its landscape. Upholt reveals how an ambitious and sometimes contentious program of engineering--government-built levees, jetties, dikes, and dams--has not only damaged once-vibrant ecosystems but may not work much longer. Carrying readers along the river's last remaining backchannels, he explores how scientists are now hoping to restore what has been lost.Rich and powerful, The Great River delivers a startling account of what happens when we try to fight against nature instead of acknowledging and embracing its power--a lesson that is all too relevant in our rapidly changing world.

Permanent Magnets for High-Speed Generators
Renewable energy technology is steadily gaining importance in the energy market because of the limited nature of fossil fuels, as well as the political pressures to reduce carbon emissions. To ensure sustainable development, adequate and affordable energy should be made available to satisfy the demand of electric energy. The University of Cape Town (UCT) collaborated with the International Research Institute Stavanger, Vrije Universiteit Brussel, Faith University, and Ain Shames University to develop a scaled down prototype of an advanced power generation system with minimum carbon emission. The upscaled model would be decentralized with a target plantsizeof10 MW to serve a small industrial community with drinking water production of 1000 m3/d. UCT was tasked with the design and development of the High Speed Permanent Magnet (HSPM) Generator subsystem, in collaboration with the UCT Electrical/Mechanical Engineering Department, to be coupled to a micro-gas turbine with a blended fuel mix which includes hydrogen, biogas and biodiesel. The main specifications of the HSPM generator are a rated speed of 30000 RPM and a power output of 10 kW. However, HSPM generators produce substantial heat especially at high operating speeds and make the thermal management of these machines difficult and complicated resulting in temperature rise which leads to demagnetization, damaged insulation, bearing starvation and reduced power output and efficiency. This book presents the design and development of the HSPM generator and focuses on both the mechanical and electrical aspects for the Interior Permanent Magnet (IPM) and Surfaced-Mounted Permanent Magnet (SPM) topologies of the HSPM generator. In particular, it is the effect of coolant velocity to enhance the HSPM generator efficiency that makes it the subject of this research.

SA's Green Treatment
SA's Green Treatment: Aeration Saves Energy (approx. 600 words) South Africa's water story is one of both necessity and challenge. With a growing population and limited freshwater resources, efficient wastewater treatment is vital. However, traditional wastewater treatment plants (WWTPs) often rely on energy-intensive processes, straining budgets and impacting the environment. Here's where the concept of "green treatment" shines - specifically, optimizing aeration for significant energy savings in WWTPs. The Energy Drain: Why Aeration Matters At the heart of biological wastewater treatment lies a process called aeration. This involves pumping air into the water to provide oxygen for microorganisms that break down organic matter. While crucial for effective treatment, aeration can be a major energy guzzler, accounting for up to 75% of a WWTP's total energy consumption [1]. In a country grappling with rising energy costs and a growing environmental consciousness, South Africa needs to find more efficient ways to manage this process. Breathing New Life into Treatment: Strategies for Aeration Efficiency Fortunately, a toolbox of solutions exists to unlock significant energy savings through aeration efficiency: Fine-Bubble Diffusers: These replace traditional coarse-bubble diffusers, creating smaller, more evenly distributed bubbles. This increases the surface area for oxygen transfer, requiring less air to achieve the same results. Think of it like switching from a garden hose to a misting nozzle - you get better coverage with less water (or in this case, air). Smart Controls: The Power of Data Imagine a WWTP that adjusts its aeration based on real-time oxygen demand, not a predetermined schedule. This is achievable with advanced process control systems. These systems monitor dissolved oxygen (DO) levels within treatment tanks and automatically adjust air flow, eliminating unnecessary aeration and wasted energy.

Seahog's Deep Sea Adventure
The development of the Seahog started in 2010. It is a third generation tethered underwater Remotely-Operated Vehicle currently in development by the Robotics and Agents Research Lab (RARL) within the Department of Mechanical Engineering at the University of Cape Town. The Seahog was established as an overhaul of two previous ROVs developed by various students within the same lab. The reason for building an in house ROV was to develop a cheap alternative to commercial offerings to specifically meet the needs described by the marine biology group at the University of Cape Town. They wanted an ROV mainly for marine life observation with a possibility of small sample collection. The Seahog was started by two master's degree students after it was deemed unfeasible to improve upon the Challenger I or Robin (the names given to the two previous ROVs). Development of the open-frame ROV Seahog was then commenced. This design was perceived to be a better design compared with the two previous ROVs' which were torpedo-shaped. This design choice offered more in terms of adaptability and maintenance as each functional feature was contained in its own module separate from other modules. For example, the Inertial Measurement Unit (IMU) is housed in its own module, so in case of a navigation feedback breakdown, debugging would be easier to perform. Table 1 shows some of the specifications or characteristics of each of the three ROVs developed by the RARL lab over the years.

Potable Water
This coursework master's dissertation (60 credits) has been developed as part of the author's Master's of Engineering Degree (MEng) in Water Quality Engineering at the University of Cape Town (UCT). The author currently works in the field of water and wastewater treatment, as a consulting engineer, with eight (8) year's relevant experience. The latter four (4) years have been mainly focussed on potable water treatment and rendering it safe for human consumption. During this time the author received some exposure to the chemical- and physical water treatment processes, however, it was felt that in-depth knowledge on the matter was lacking. Therefore, the focus of this dissertation pertains to potable water treatment only and its emphasis is on the following aspects: - Raw water quality: What should one test for in the raw water, when and why should you test for it and how can it be removed or used to inform the process design. - Process design: A user friendly excel based software model has been developed by the author, that enables the user to perform a process design that should be able to adequately treat most surface waters (from rivers and dams). Water is a precious and limited resource that plays a vital role in sustaining life on earth. Also, 60% of an adult human body consists of water and if not consumed in sufficient amounts, can lead to dehydration, and ultimately result in fatality. However, water does not only fulfil a critical survival need. It is also used in many other applications. For example, in the municipal sphere water is used for various other purposes, such as bathing, brushing of teeth, washing of clothes, transporting excrement (in the form of wastewater), preparing food, watering of gardens, to name but a few. In the industrial sector water can be used for cooling, food and drink production, washing etc. The list goes on and on. In most cases water in its natural form is not suitable for use in any of the above-mentioned applications and mu
Funding Renewables
The energy policy shaping space is influenced by the demands of sustainability goals, associated with the complexity of the socio-economic and biophysical systems. Rising fossil fuel prices, societal impacts of energy use and observed climate change make the exploration of renewable energy more important than ever (Kowalski et al., 2008). This paradigm shift, combined with the considerable amount of infrastructure and investment required for renewable energy, has led to an increasing presence of private and institutional investors including insurers, exposed to various risks. According to the US Energy Information Administration (EIA), world energy consumption will grow by 48% between the period 2012-2040 (US EIA, 2017: online). This trend is attributable to strong economic growth emerging from Non- Organisation for Economic Cooperation and Development (OECD) countries (US EIA, 2017: online), including South Africa. Working as an alternative to fossil fuels, renewable energy technologies will play an integral role in meeting the world's growing energy demand adding to the global energy mix (IRENA, 2016:14). Furthermore, the share of renewables in the global energy mix can be cost-effectively doubled by 2030 using existing technologies. Along with energy conservation practices, an overall improvement in the global energy profile can be achieved which would significantly reduce greenhouse gas emissions and put the world on track to limit global mean temperature rise to below 2簞 Celsius (IRENA, 2016:14). This level of renewable energy deployment means scaling up current investment in renewables to 500 billion US dollars (USD) per year by 2020. Global investment must then reach USD 900 billion each year up to 2030 (IRENA, 2016:14). Almost two-thirds of this investment would be in the power sector, but renewables for heat and transport also need to grow significantly. Developing markets with fast growing energy demand will require the largest increase in investment (IREN
Waste to Bricks

Beyond Minerals
Our world faces a raw deal: rising demand for resources clashes with the need for a sustainable future. As populations grow and economies develop, the pressure on raw materials intensifies. This creates a precarious tightrope walk - meeting current needs without compromising the environment for generations to come. The answer lies in a paradigm shift. Focusing solely on raw demand is unsustainable. We must prioritize efficiency, utilizing resources more effectively. Innovation in recycling, reuse, and alternative materials is key. Sustainable practices throughout the supply chain - from responsible sourcing to minimizing waste - are essential. The path to a sustainable future paved with raw materials requires a multi-stakeholder approach. Consumers must embrace responsible consumption, while industries must prioritize longevity and circularity in design. Collaboration between governments, businesses, and research institutions can unlock new technologies and responsible management practices. By reconciling raw demand with sustainability, we can create a future of abundance without sacrificing the planet's well-being.
