Municipalities in developing countries are increasingly producing solid and liquid wastes. The management of those waste are relevant because of their impact to the environment and health. For instance, disposing waste in surrounding areas become vectors for the development of diseases, and they contribute to produce lixiviates which are already infiltrating into the water table. In addition, solid waste accounts for 5% of the total GHG emission. This becomes an environmental issue that has to be resolved.
Not to be confused with remote viewing which finds its home in parapsychology, remote sensing involves collecting data about an object without having any physical contact with the object being observed. There are several types of remote sensing systems used in agriculture but the most common is a passive system that senses the electromagnetic energy reflected from plants. The sun is the most common source of energy for passive systems.
Production of electricity from waste has the potential of providing up to 83.8 TeraWatt hours, which is about 20% of the electricity needed in Africa by 2025. This is according to a study co-authored by the European Commission Joint Research Centre. However, this requires stringent waste management policies to be put in place, and today Africa lacks the adequate infrastructure needed to install these environmentally friendly methods.
Precision, smart agriculture, Ag 3.0, any name is fine. The Internet of Things is beginning to change agricultural practices, from monitoting farms, collecting relevant farm data, to empowering farmers receive this information and take necessary timely decisions. When used together with weather data from sattellite and other systems, alongside smartphones, cloud platforms and satellite, the result is cost reduction and better yields.
To GM or not to GM remains the Shakespearean conundrum a number of African countries still find themselves in. But is there a way to exploit biotechnology without causing such public unease? Selection with Markers and Advance Reproductive Technology (SMART) breeding could be the answer.
Youths are likely to act more about climate change in future as revealed in a recent survey by GC Consulting. Commissioned after the Marrakech COP 22, the survey revealed that many of them are willing to take action especially in the areas of recycling. Youths also recognize the important role governments, private sector, and international communities have to play in averting climate change effects.
In late 2004, Kisumu bay, Lake Victoria, was covered in a blue-green hue. The algal bloom - a proliferation of cyanobacteria – demarcated an area of low oxygen and eventually decomposing algae, causing fish to suffocate or flee and contaminating the drinking water- a dead zone. Adapt-N, a software programme developed by researchers at Cornell University seeks to solve this problem.
