تُعد طريقة الري بالقٌلة (إناء فخاري مدفون) واحد من أكثر الأنظمة المعروفة كفاءة وهي مثالية للمزارعين الصغار، بالرغم من أن العمل بالانظمة التقليدية الفعالة وذات الفائدة الكبيرة في المزارع والحدائق صغيرة ومتوسطة الحجم لم يكن معروفاً في وقتنا الحالي إلا مؤخراً. لقد تعلمت هذه الطريقة خلال قرائتي لكتاب صيني عن الزراعة من قبل 2000 عام، حيث كانوا يستخدمون ري القُلة بإناء طيني مدفون وغير مصقول مليء بالماء للتحكم بالري للنباتات، حيث يتسرب الماء من خلال الجدران الطينية بمعدل كمية استهلاك النبات للماء. لماذا القٌلة؟ أثبتت دراسة أجريت في كينيا عام 2013، أن نظام الري بالقُلل كان اكثر كفاءةً من الري … Continue reading →

3 Comments

The notion of Extended Producer Responsibility (EPR) has been part of the waste policy for a long time, particularly within the OECD countries. According to the OECD, EPR “aims to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the post-consumer phase” [1]. EPR alleviates the burden of Public Administrations for managing end-of-life products, while -if properly designed- incentivising waste prevention and recycling. Current Limitations of EPR After years of implementation it can be argued that Extended Producer Responsibility has not in fact been so extended. Several limitations are common: a) producer … Continue reading →

Thinking about wind power brings up pictures of massive turbines sprawling out over wide fields. Yet this classic scene doesn’t show the whole story. Wind tech is getting better, and small wind turbines (SWTs) are on the rise. This technology has the potential to shake things up with a new way to use wind power. It makes it easier and more adaptable for individuals and companies to make their own clean energy, gain more energy independence, and add some green energy to the energy mix.

Atmospheric rivers actually mean rivers of water in our skies. But what is the science behind this phenomena that can become a very serious threat across regions of the globe. An atmospheric river (also known as AR) is a long and narrow flowing stream of water, actually condensed water vapour, in the atmosphere. It is capable of producing significant levels of rain and snow. When the atmospheric river moves across land and over mountainous terrain, the water vapour rises and cools to create very heavy precipitation or snowfall. Many atmospheric rivers are of moderate size but some are exceptionally powerful … Continue reading →
