EPSC 181 — Introduction to the Human-Earth System — Winter 2023 Assignment 4 Human activities and energy use Please enter your answers in a new document with your name on it (preferably typed, but handwritten and photographed is also fine, as long as it is legible!). Drawings can be done by hand or using software. Upload your completed assignment with your name on it in pdf format to myCourses. Due: Monday March 6 at 1 pm. No late assignments will be accepted. Part 1: The EPSC 181 Student Day! (7 pts) This part requires that you complete a Time Use Diary for one entire day. You can choose any day of the week you want, but make sure it is a real, continuous day (no combining parts of di ff erent days!). You will do this by making an anonymous copy of a spreadsheet, filling this out, and then submitting it anonymously. Please start with the google spreadsheet located here Make your own copy to fill out: - go to ‘File’ \ ‘Make a Copy’ and then click ‘OK’ (ignore the options). - Please do not rename the file or put your name anywhere on the sheet (so that it stays anonymous). Indicate whether the day you are recording is a weekend /holiday by entering YES or NO in the box at the top. As best you can, go through each 30 minute time slot and fill in the Activity column with the numbered codes (from 1 to 18) shown on the right side of the sheet that best reflects what you did most of the time, as a primary activity. See page 4 of the assignment for descriptions of the activities. At the same time, fill in the corresponding experience code that best reflects your general emotional response to each activity (from 1 to 5). Next, use the METs in the standard activity compendium (attached) to assign an approximate MET to each activity. a) What challenges did you encounter in assigning activities and experiences? b) What was your average MET for the day? How accurate would you say this is? (+/- range) You don’t need to hand your sheet in directly - but instead, please contribute to citizen science! Page of 1 4

To do this, in your completed, anonymous sheet, 1. go to Share 2. Under ‘Get link’, click on ‘Change to anyone with the link’, and then click ‘Copy link’, and paste it anonymously here. The results will be anonymously compiled and presented in class as an average and overall distribution. Part 2: Global food production (4 pts) The average time spent on food growth on collection, averaged across all humans (i.e. in the global human day), is 0.8h person -1 day -1 . a) Estimate the total daily rate of somatic energy (in J per day) that is currently invested - globally, by all persons - in this activity. Assume an average total MET for this activity of 4, an energy consumption of 1.1 W kg -1 per MET, and average human mass of 50 kg. b) Assume each person in the global population consumes 10 MJ of food energy per day, which represents the total energy provided by all food growth and collection. What is the ratio between this total food energy provided to all humans and the food energy consumed in order to do the agricultural activity in part (a)? (In other words, how many joules of food energy are provided for every joule of somatic energy invested?) Part 3: Accelerating travel (7 pts) The global human day shows that people travel, on average, for about 1 h per day. Remarkably, this does not vary with di ff erences in the wealth of a country, or the mode of transport. Assume that the distance x traveled by people during a day can be described by the equation where A x is the average time spent traveling (in s), P x is the rate of energy consumption (in W), and ε x is the energy e ffi ciency of travel. Here the energy e ffi ciency ε x is in terms of how far the person travels for a given amount if energy, in units of km MJ -1 . a) if a person of mass 50 kg walks for a distance of x = 5 km in 1 h every day, at an average P x of 3 METs, how much somatic energy do they expend (in MJ)? Use this to calculate ε x . (You will probably want to rearrange the equation first, to solve for ε x ) x = A x P x ϵ x Page of 2 4

Includes the time of the traveler, as well as any vehicle operator. 14 Allocation Altering the time allocation, and control of access to objects and spatial domains, for other humans. Includes diverse decision-making, task allocation, negotiation, discussion, and record-keeping activities. 15 Meals Activities centered on eating and drinking, including associated socializing. 16 Active recreation Recreation that involves an elevated metabolic activity (including light physical activity), including with a fitness motivation. 17 Social & interactive stimulation Socializing or any other activities undertaken for the sake of experience that engage motor or linguistic output. Includes play, text messaging. 18 Passive observation Looking/listening without engaging, i.e. neither involving interactive movement or generating written or spoken language. Can range from quiet rest to watching an action movie. Page of 4 4
