Snippets: Monitoring crop diseases, infrastructure health and wildlife

  "If you can't measure it, can you fix it?"   One of the greatest challenges faced by almost everyone working in a clean technology field - water, agriculture, energy, climate, forestry, wildlife, soils, corporate sustainability, smart cities - is the challenge of monitoring. At its essence,this is the challenge of   what needs to be measured, how often and how accurately can it be done . Traditional methods of monitoring have involved sensors (of different levels of accuracy) placed in specific locations and the data removed and processed off-site by engineers and field analysts at specific time intervals. This is a time-consuming process, with data that isn't as frequent or as spatially dense or with as many parameters as decision makers and scientists would like - but, until recently that's been the best that we've had. The advent of smartphones, high-frequency and high resolution satellite data and the whole Internet of Things (IoT) is changing this parad

Data Science For Water In California

I was at the   Open Water for California   conference in Sacramento last week - a conference dedicated to data science for water, with a focus on California. The conference itself was well attended with people from many different sectors - academia, government, non-profits and community members. What was particularly interesting is that it had an entire track devoted to hackathons and building new tools to solve some of the pressing problems being faced in water today - as well as the more traditional sessions with talks on the latest research and tools for the water sector.   The hackathon were focused on issues related to understanding trash movement into water sources (especially plastic), building consumer confidence reports on water safety and tools to better understand drinking water sources. There was a lot of interest in water safety understandably, with Flint still fresh in our minds and the recent focus on water quality issues in California communities affected by the wildfir

Coding, Databases, GIS and other tools for a clean tech data scientist

  As we saw in the last post, a data scientist's role requires the ability to  capture, process, analyze and visualize the data.  While there are some off the shelf software tools, most applications in the clean tech and data science space require knowledge of a programming language in order to perform many of the tasks effectively.  The popular choices for a clean tech data scientist are 1.   Python : Python is probably the single most critical element in the data scientist’s toolkit. It’s a flexible, easily learnt computer language that is powerful because of the large stack of libraries that have been developed. Do you need to figure out how to get data from a website – or train a machine learning algorithm? The chances are that there is an existing library in Python that can be plugged into your code.     The main libraries that are necessary for any of the data science use cases are   scipy, numpy, statsmodel and pandas . These can be used for building a predictive model using

A day in the life of a clean tech data scientist

  We've all got pictures in our mind of what certain occupations entail - and this may be very different from what actually happens! When I started my career as an environmental engineer working in a consulting firm, I had this vision of working outdoors all the time, helping to save the planet, interacting with community members who were anxious to solve the problem...... but the actual work turned out to be quite different. I spent at least half of my time in the office filing out forms and paperwork that were needed to meet regulations, analyzing data and my interactions with community members usually meant chatting with them about the samples we were collecting, if we were going to be in their way, and the weather that day. So what's a day in the life of a clean tech data scientist like? Sadly, it's not just running around the office shouting "Eureka" because you found something amazing that will help the planet - though those days do come by! Most of the time

Becoming A Clean Tech Data Scientist

In the last few posts, we’ve talked about the type of careers and skills that are needed in order to become a clean tech data scientist. The field is expanding rapidly right now, with openings in almost every clean tech sector and across a wide range of organizations. Just check out our   jobs portal   to see the range of positions available right now - and these are just the ones we’ve highlighted!   But how do you become a clean tech data scientist?   Since this is a relatively new field, there really haven’t been degrees or courses so far that said “Masters in Environmental Data Science” or “PhD in Data Science and Clean Technology”! Of course, this is changing with a few universities beginning to offer programs in earth systems and data science or clean technology and data science, but these are still only a few in number and started only in the last couple of years.     If you’re starting your career and are interested in this field, the universities that offer specific coursework

I’m a data scientist interested in clean technology - what can I do? Careers in Clean Technology and Data Science continued

  Last time, we looked at the skills that someone from a clean technology background would need to acquire to become a full - fledged clean tech data scientist. Today, we’ll take a look at the other side of the balance - if you have a data science background, then how can your skills be applied in the clean technology sector?   Someone who is already a data scientist or is in the software field and looking to break into a clean technology industry or company has a very different problem from the clean tech specialist. To start with, your skills are most likely in algorithms, statistics and data engineering. That means that you can code, build prototype algorithms, build hardware/software interfaces if you’re in sensors or robotics and you know how to store and access data. You probably already have a PhD in physics or maths or another engineering domain or maybe a Masters in computer science.     So, the data science and engineering skills that the clean tech specialist would need to p

I have a clean technology background - now what? Careers in Clean Technology and Data Science continued

  We had a great time hosting our webinar on careers last month- a big thank you to all of you who signed up and attended and asked all those interesting questions! If you’re interested in getting the slides, they can now be downloaded for free   here .   And now, to continue with our series of posts on this topic.. What kind of careers can be built at the intersection of clean technology and data science? The figure above shows the sectors in both clean technology and data science.  The kind of career you want to build will really depend on which end of the balance you’re sitting on. Are you someone who comes from a clean technology background and wants to pick up data science skills? Or are you someone who has a strong data science/software background and are interested in applying those skills to problems in clean technology? This will also govern the skills you will need to pick up or expand on as you build your career. If you’re coming from a clean tech background, you’re probably
