مستجمعات المياه الصحية أولوية حرجة لدفع التنمية المستدامة

تُعرّف مستجمعات المياه أو مساقط المياه (Watershed) بأنها مساحة من الأرض تُصرّف المياه الناشئة عن هطول الأمطار وانصهار الثلوج وتوجه تدفقها لتصب باتجاه الجداول والأنهار، وفي النهاية إلى نقاط التدفق (Outflow points) التي تصب في مستودعات المياه الأكبر حجما مثل الخلجان والمحيطات. ولكل جسم مائي مستجمع مياه أو أكثر. وتسمى أيضًا أحواض الأنهار أو أحواض التصريف (Drainage Basin). كما تُسمّى مصائد المياه (Catchment)، لأن الأرض الصاعدة والمرتفعة (Upstream) تصطاد المياه ومن ثم تجري إلى أسفل التل (Downstream) في اتجاه مجرى النهر أو الجدول القريب. تتكون المستجمعات المائية من وديان منحدرة تحيط بها قمم وتلال مرتفعة. ويتم تحديد حدود مستجمعات المياه … Continue reading

What Makes a Community Fundraiser Sustainable

There’s a strange kind of energy around a good fundraiser. You feel it before it starts — the quiet buzz in the background, the last-minute text chains, the smell of coffee at an early morning setup. It’s messy, hopeful, human. But here’s the hard truth: most community fundraisers don’t last. According to research from NetSuite, only about 50% of nonprofit organizations are successful, and roughly 30% dissolve in less than ten years. Not because people stop caring, but because the spark isn’t supported by structure. Sustainability isn’t about how big your event gets or how much you raise. It’s about … Continue reading

Can Institutional Capital Drive Sustainable Blockchain Adoption?

In recent years, the sustainability debate in blockchain has taken a new turn. What was once a side discussion among environmental critics has now become a mainstream issue discussed by governments, investors, and other large crypto exchanges. The question at this stage of industry development is not whether blockchain must be made more environmentally friendly, but who will take the lead in this process. There is growing interest in institutional capital as a potential catalyst for more responsible, greener blockchain ecosystems. The involvement of institutions in digital assets has been increasing, bringing additional pressures, including governance requirements and long-term investment … Continue reading

The Effects of Waste on Palestinians’ Health And Environment

The State of Palestine faces multiple environmental challenges, most of them linked to waste management. The United Nations Environment Programme (UNEP) highlighted in 2020 that “47% of all waste, including hazardous waste, is disposed of in unsanitary dump sites”. The figures shared by the  Heinrich Böll Foundation in Plastic Atlas focused on municipal solid waste and underlined that 65% of the waste is disposed of in landfills and 32% in illegal dumping sites. Just 3% of the rubbish is recycled or reused. The sociopolitical and economic context of the country dominated by the occupation makes even bigger the global challenge … Continue reading

Energy-efficient Building Envelopes in Oman – A Study

In Oman, extreme hot weather conditions and thermally inefficient building envelopes have led to high cooling loads in residential units. Residential buildings serve a smaller number of occupants per unit, when compared to other sectors in the building industry. Also, mechanical, electrical and other energy-intensive equipment are relatively lesser in quantity and complexity. Yet, as per statistics, the residential sector is the largest consumer of electricity in the industry. In Oman, the residential sector consumes most of the electricity produced, with over 70 % of the load contributed by cooling using air conditioners (Zurigat et al., 2003). A major reason … Continue reading

How To Trade Sustainable Instruments Online

Many people assume that sustainability and online trading doesn’t go well together, but where are here to prove the opposite. In fact, we would argue that online trading is the best type of financial investment for people that encourage sustainability and in this post, we’ll explain why that is. What is Online Trading? In this guide, we refer to online trading as trading done using online brokers, also known as CFD trading. These brokers provide traders access to trading platforms where you can trade everything from stocks and commodities to cryptocurrencies and forex. Now, unlike a traditional stockbroker, for example, … Continue reading

زرع الأشجار لم يكن بهذه السهولة

ظاهرة الاحتباس الحراري  كانت كلمة جديدة بالنسبة لي عندما كنت في الصف السادس. مندهش من التأثيرات، سألت أستاذ العلوم، “إذا كان بإمكان طلاب مدرستنا زرع الأشجار؟”. كانت الفكرة هي زراعة حوالي 500 شجرة. لسوء الحظ، جاء الرد بالنفي. في الواقع، لقد كان تحديًا عمليًا بالنسبة لنا هو الحصول على المساحة لزرع والإبقاء على 500 شجرة، وكان ذلك نتاج افكاري وأنا طفل. في وقت لاحق، انتهى بنا المطاف في زراعة خمسة أشجار فقط، عاش منها اثنان. الآن عندما أزور مدرستي، وأنظر إلى الشجرتين اشعر بالفرح. وتعصف بذهني الافكار، ماذا لو زرعنا 500 شجرة وتمكنا من حماية أكبر عدد ممكن من ال … Continue reading

Green Hydrogen: Global Dynamics, MENA Perspectives and Algeria’s Decarbonization Strategy

Global energy systems are undergoing a structural transformation driven by the urgency of climate change mitigation, long-term sustainability concerns, and the need to reduce dependence on fossil fuels. The Paris Agreement and subsequent national commitments to carbon neutrality by mid-century have reinforced the necessity of deep and rapid reductions in greenhouse gas emissions across all sectors of the economy. Although renewable electricity generation—particularly solar photovoltaics and wind power—has expanded significantly over the past decade, the electrification of final energy demand faces intrinsic limitations in sectors characterized by high-temperature industrial processes, energy-dense fuels, and long-duration storage requirements [1]. Green hydrogen has … Continue reading

Sputtering Targets in Solar Panel Manufacturing: The Hidden Materials Powering Solar Efficiency

Solar panels look simple once they are installed. Glass on top, metal frame around, sunlight goes in and power comes out but anyone working with commercial solar knows the real problem starts later. Heat slowly eats away at performance. Dust sticks. Moisture sneaks in. UV exposure causes long term degradation, especially in harsh climates. Over time, efficiency drops even when everything looks fine from the outside. This is where sputtering targets manufacturers comes in, quietly doing the heavy lifting. Sputtering targets enable ultra thin conductive and protective layers that sit inside the panel like invisible armor. These layers improve electrical … Continue reading

Carbon Tax: The Missing Link Between Climate Ambition and Real Action

At a time when climate change has emerged as one of the major determinants of economic, social, and geopolitical trajectories in the 21st century, the question is no longer whether action is needed, but how to act effectively, credibly, and sustainably. Nationally Determined Contributions (NDCs), the operational pillars of the Paris Agreement, embody this collective commitment to keeping the rise in global average temperature well below 2 °C, with efforts to limit it to 1.5 °C [1]. Yet, despite the proliferation of pledges, a persistent gap remains between declared ambitions and actual global emission trajectories, which continue to rise at a pace … Continue reading

Reasons Why LEDs are the Future of Sustainable Lighting

You may well ask: Do LEDs now lead the way, light the way?  You may also ask: Are CFLs out? Perhaps those of us who have not changed need to change and here are the reasons why. It was not so long ago that I stood in the middle of the lighting aisle wondering which light bulb do I purchase. Which type is the most efficient? What about the range of prices being broader than the range of options. There were all kinds of options ranging from incandescent bulbs which were cheap but wasteful, compact fluorescents (CFLs) supposed to be … Continue reading

العوامل النفسية والاجتماعية المؤثرة في السلوك البيئي

يميل بعض الأفراد إلى التفسير القائم على الحتمية الدينية؛ إذ يُنظر إلى الكوارث البيئية باعتبارها أمورًا مقدّرة سلفًا لأن الله خلق الأرض، مما يقلّل من الشعور بالقلق أو المسؤولية. هذا الموقف قد يشكّل غطاءً مريحًا رغم أن العديد من التقاليد الدينية تؤكد بوضوح على مسؤولية الإنسان في إدارة الخليقة. في المقابل، يرى آخرون أن المشكلات البيئية بعيدة عنهم جغرافيًا أو اجتماعيًا أو زمنيًا  وبالتالي لا تُدرك كتهديد عاجل، مما يضعف الدافع نحو الفعل. هنا يظهر أثر “المسافة النفسية” كما تصفها نظرية مستويات التصور (Construal Level Theory): كلما بدا التهديد بعيدًا في الزمن أو المكان أو الصلة الاجتماعية، أصبح أكثر تجريدًا … Continue reading
