عمل الإنسان منذ عصور قديمة على إفساد البيئة التي يعيش فيها وأخل بتوازنها وجلب لنفسه مخاطر ومشاكل عديدة لم يقدر على تحملها ، من جراء كثرة الملوثات مثل نفايات المصانع والمنازل والمزارع ومخلفات المدن والمواد البلاستيكية ووسائل النقل والمبيدات والأسمدة …وتعتبر المبيدات الزراعية من أهم وأخطر ملوثات البيئة فهي مواد كيميائية سامة تستخدم لمكافحة الآفات وتؤثرعلى العمليات الحيوية للعديد من الكائنات الحية ، وهي أيضاً سامة للإنسان والحيوان. وقد أحدث الإنسان تغييراً في التوازن البيئي في مناطق عديدة، بإستغلاله لها واستثماره لأرضها، فعدد الحيوانات التي تعيش في المناطق إنقرضت بسبب الإخلال في التوازن، وأصبح يتزايد على نطاقات واسعة، وهذا السبب … Continue reading →

Microplastics are everywhere and we need to know the impacts of these tiny plastic particles. These tiny particles are in our water, our food, in the air, in the soil, in the plants. Everywhere is anywhere and anywhere is everywhere. What are microplastics? Broken down plastic objects and items that are randomly discarded or disposed of in approved manner. The plastic particles are less than 5 millimeters requiring a microscope to view the particles. Even smaller particles are referred to as nanoplastics. Because the globe is so ensconced in the use of plastics domestically, in industry, medical equipment and applications, … Continue reading →

Trash Talk from Doha

On arriving a few years ago from a town in the UK that boasts a university course in waste management, and a very efficient weekly recyclable waste collection from our houses, I was a bit shocked, like many Europeans by how difficult it was to recycle in Doha. Having had the moral obligation to recycle drummed into me since I was quite young, I felt guilty throwing away all my waste into one bin, destined to fill up a huge smelly hole in the desert, where it would take a long time, if not forever to biodegrade. The Real Picture … Continue reading →

In recent years, low-carbohydrate diets have gained popularity primarily for their weight loss benefits. However, what many people don’t realize is that reducing carbohydrate consumption can also have significant positive impacts on the environment. This dual benefit makes low-carb eating an attractive option for those concerned about both personal health and ecological sustainability. Low Carb Diets and Weight Loss Connection Low-carb diets work by reducing insulin levels in the body. When you consume fewer carbohydrates, especially refined ones like white bread, pasta, and sugar, your body produces less insulin. With lower insulin levels, your body more easily accesses stored fat … Continue reading →

Acequias for More Sustainable Irrigation: Rediscover an Ancient Technology

By | | , , ,
Leave a comment

Arid and semi-arid lands develop when climatic conditions create water limitations and the water lost through evaporation exceeds the water gained from precipitation.  Severe water limitations and climatic extremes make these arid and semi-arid regions very dependent on careful and conservative water management. Traditional practices that use only gravity to distribute water in these environments have been used for thousands of years, but have been little studied and are under-appreciated. These gravity-based canal systems are known as acequia (Spanish) and secondary and lateral ditches are called laterales, linderos, sangrias, or venitas. The head gates that divide and control water flow … Continue reading →
