In Nairobi, there has been unsuccessful attempts to introduce BRT. Construction of the infrastructure stopped half way through. Some of the supportive measures that were part of the core plan is to provide parking for private cars at the BRT station to encourage people with private cars coming from the suburbs to use public transport to the Nairobi CBD. This...

I live in Nairobi, I think a major shift is needed to develop safe, efficient, and cost effective public transport system. Currently we have a small sized vehicles even as few as 8 seater as part of public service vehicles, and they are many of them ultimately leading to inneficies, time wastage, insecurity, erratic prices, and more pollution.

This is an interesting discussion. I live in Nairobi, Kenya. The negative impacts of car developments include but not limited to air and sound pollution. Kenyans mostly import second hand Japanese vehicles. While vehicles are required to be roadworthy, we don't have rules regulating vehicle maintenance and engine emissions, and noise pollution. It is very...

It's my profession as an Environmental Scientist. Additionally, I'm very passionate about reduction of carbon emissions at a business and individual level. In Kenya, climate change is a big issue and this year there were massive deaths of wild and domestic animals due to a 3 year drought.

This is a very interesting course. As an environmental scientist, I expect this course to enhance my understanding of invisible processes that shape the visible environment I interact with every day.

Nyahoro Maina made a comment
Climate data is really enormous which makes it hard for non specialists to flip through the volumes of records and make sense out of it. Visualizations provide a concise, understandable, and less engaging way of communicating important information about climate issues to interested people, policy makers and many other people who use climate information to...

I'm surprised that weather forecasting is such a complex activity that it has to use super computers.

The bottom line of any business is profitability.. The case studies indicate the the margins were enhanced by use of big data.. What else to say, use of it works!!

Nyahoro Maina made a comment
One of the challenges we are facing today with big data is being able to systhesize, understand, and deliver outputs that can be easily understood by ordinary people where necessary. So Ed's Visualizations make it very easy to understand deliverables of big data by an ordinary person.

I am an Environmental Scientist with keen interest in earth observation/Remote sensing. Satelites are sources of big data and I wish to learn how the data can be ultilized in different fields.

The mobile phones are probably the major sources of big data which we collect in the process of using them to communicate, learn, bank, record, share etc.

Hi collegues! Climate change simply means catastrophes, disputes, poverty, scarcity etc. The change starts with the physical environment before it ecalates to social-economic, and political issues affecting so many people, literally everywhere on the globe.

I think the biggest threat to pollinators is the damaging effect of human activities. Polinators are no longer safe from pestcides, traps, and destruction of habitats. This is despite their undeniable role in food production. Diseases and pests have been there historically, partly they have a role of natural population control. However, a combination of...

Nyahoro Maina made a comment
When coral bleaching occurs, the specialists are affected rapidly because their food chain is dependent on the coral. Generalists are also affected gradually which may reduce their population due to insufficient food in the habitat. However, the scale depends on the number of corals affected.
On the other hand, organisms try to adapt to changes such as... -
Nyahoro Maina made a comment
I think with more links there is more resilience but the resistance is not affected.
The pattern of links matters because it indicates the extent to which species depend on others. Such that when a key organism is eliminated from the food chain in which many species depend on, the species population can decline rapidly. The most important species are those... -
Nyahoro Maina made a comment
I think pollution and careless human activities are the biggest threats to marine and terrestrial ecosystems. In so many places we don't just exploit the resources for our own good, but we end up damaging the environment thereby putting other species at risk. I think we humans are selfish. Consider for example the tons of plastic waste that is draining to the...

A good study there. However, it only considers the bird strikes in relation to the bird population. Man made features can have other adverse effects on the behaviour of birds such as breeding because they change the natural landscape of the area, and which the study did not evaluate. Nonetheless, when a study is conducted prior to construction It's helps since...

Hello Frances, I am glad you mentioned the link between farming and conservation.. I guess so many farmers are very ignorant about the intricate relationship between environmental conservation and sustainable agriculture . But as you mentioned, it's good that people can now see that when we keep destroying the environment with agrochemicals, then production...

I go for the individualistic theory.. Nature is complex as a matter of fact and the behavioral responses to certain stressors can vary widely even within a population. Members single species of vegetation can behave differently when subjected to similar conditions due to genetics and individual adaptation strategies.. Plants learn and evolve..as well as...

A good example of a community of organisms in my neighborhood is a water pod. It has both plants and animals. Common plants are grass and water lily. Animals include frogs and their tadpoles in the water. Pod scatters and dragon flies on the water surface. I also see some species including earthworms burrowing in the mud.

Nyahoro Maina made a comment
Basically speaking, I would say that a human being is a super animal, yes animal.. This is considering that he shares the environment with all the other animals and plants species. What we eat is nothing different from what other animals consume. So we are part of an ecosystem with other organisms without choice. When the quality of air and water and air is...

Correct Hernando, if one would have such information before a disaster, it is so good. But disasters also modify an area significantly by destruction of infrastructure requiring urgent information about the new state of the area before any organized recovery can take place. Here, earth observation has been so helpful.
-
Nyahoro Maina made a comment
Incredible history of remote sensing spanning over a century. Basically, the benefits of large scale view of an area, especially when it is not accessible, for example during disasters is crucial for disaster management. In my perspective, this ability remains one of the most remarkable applications of Earth Observation Technologies.

Elite capture occurs commonly as an interplay of power and politics. In a country where being more powerful(politically) means more control and more wealthy, then Elite Capture cannot express itself in a better way. I mean being a "leader" means violation of basic institutional rules, and one gets away with it. For example in paying taxes, only the powerful...

Having watched the video, by all means i believe the reality of these two principles will take time. I doubt If it will ever be a reality anytime soon. But basically they give us a glimpse of how equality can be achieved in a word of diversity and unequal opportunities.
-
Nyahoro Maina made a comment
I chose equality and respect for nature. Many still chose equality as one of the major rules. But I think this is the hardest to actualize. People are not the same by all means and standards, they have different perspectives to the use of resources, family, wealth and many other social economic issues. Trying to reach for equality is a nightmare, almost...

Certainly. The relationships between the biotic and abiotic components are complex and necessary for ecosystem functionality. Thank you.
-
Nyahoro Maina made a comment
An indicator species is the one whose presence in an area indicates it is the most suitable conditions for its survival and its disappearance indicates a change in the ecological conditions, sometimes ecological balance of that area.
-
Nyahoro Maina made a comment
I believe the most interesting thing in the ecosystem is the physical action of sea tide since it brings physical, chemical and structural modifications which heavily influence the order and functionality of the biotic and abiotic components of the rock pool.
-
Nyahoro Maina made a comment
I can define an ecosystem as "the interaction between abiotic and biotic components through the processes of energy flow and nutrients recycling"
-
Nyahoro Maina made a comment
The second definition is more inclusive, with both abiotic and biotic components , and the best definition of an ecosystem

The change is surely massive especially in tropical forests. This trend worries me. If this much change can occour in 10-15 yrs, what about a similar period to come. Considering the role of tropical forests in carbon sequestration and climate regulation, then am worried climate change will persist. Am i thinking right?
