on oct. 17, 2024, as a part of the world food forum in rome, italy, the fao hosted a discussion session for high-level leaders and representatives to discuss their global framework on water scarcity in agriculture, or wasag.

wasag is a partnership initiative of fao and brings together “government agencies, international organizations, research institutions, advocacy groups and professional/membership organizations,” according to their website.

their discussion session outlined 10 ways that wasag plans to build upon their partnership with the fao and combat water scarcity. the session had three goals in mind:

• to enhance collaboration and mobilize commitments,
• to agree on key wasag governance, and
• to highlight priorities in addressing scarcity in agriculture, while strengthening the connections between the agriculture and water sectors.

water scarcity has already caused massive crop failures worldwide, and this issue will only continue to grow. the fao reports that around the world we’ll need to produce 50% more food by 2050, when the global population is expected to hit 10 billion — requiring at least 25% more water. the broader goal of wasag is to make water more accessible to ensure a higher level of food security. 

“wasag is core to fao’s commitment to integrated water resources management for the effective transformation of global agrifood systems to be more efficient, more inclusive, more resilient and more sustainable,” fao director-general qu dongyu stated on the wasag website. 

wasag was created in 2016 to help fao uphold its commitments related to the 2030 sustainable development agenda. wasag focuses on sustainable development goals 2 and 6, which include alleviating poverty and creating clean water and sanitation, respectively.

the 10 actions presented at the rome conference ranged from supporting partnerships between wasag and all fao member nations that address water scarcity, to establishing a technical advisory committee that would provide technical advice to wasag members and partners.

the technical advisory committee will meet twice a year as well as annually with the leaders of working groups and task forces. there are six groups of wasag, including water and migration, drought preparedness, financing mechanisms, water and nutrition, sustainable agricultural water use, and saline agriculture.  

one of the youth representatives from the world food forum youth assembly, maggie markow, suggested that the advisory committee would need to expand its scope to be successful.

“let this water dialogue be a stark reminder water is just not technical, it is political, and it is our responsibility to ensure it is accessible to all,” markow said. 

besides markow, dongyu also said people should not only learn the technology behind combating water scarcity but also learn why it is so important to fight against water scarcity and its related issues.

“we should be learning the spirit of fighting against the situations we are facing like climate and weather change,” dongyu said. 

wasag ended their declaration reiterating they want to make all their resources established in other parts of the declaration available for their partners. they also stated they want to keep working with fao, as supported by the director of the land and water division at fao li lifeng.

“fao is supporting all member countries to jointly address the water scarcity challenges. “wasag is a flagship partnership in the fao new water journey. we look forward to hearing solutions and experiences that can be brought to the global arena,” lifeng stated on the wasag website.

north america has the highest diversity of freshwater mussels in the world, with almost 300 different species. also known as the “liver of the river,” freshwater mussels filter and protect aquatic ecosystems. despite being able to filter between eight and 15 gallons of water per day, mussels face a myriad of threats including industrial development which affected these populations as factories popped up along the schuylkill river during the industrial revolution. 

at its worst, philadelphians said the river did not even resemble water. now, scientists at the fairmount water works (fww) freshwater mussel hatchery are working tirelessly to create a space where visitors can learn firsthand about the life of a freshwater mussel and how cleaner river water depends on one of the most imperiled aquatic animals in north america.

in 2017, the philadelphia water department teamed up with the partnership for the delaware estuary to open the hatchery, which is free to the public, and located within the fww interpretive center. the hatchery was designed and imagined by the academy of natural sciences at drexel university, victoria prizzia of habithéque, inc., and artist stacy levy.

introducing philadelphians to the power of the mussel

the hatchery sits along the schuylkill river, which provides 40% of philadelphians with drinking water, with the other 60% being provided by the delaware river. the location of the hatchery, along with preserving pieces of architecture from the original waterworks building are all intentional. according to stacey heffernan, the environmental education planner, “mussels are the gateway animal to get people to care for the waterways.” the hatchery’s proximity to the schuylkill, one of philadelphia’s most iconic green spaces, places it in a culturally significant and emotionally resonant site for many locals.  

in addition to this, the hatchery also runs educational programs for philadelphia youth. four schools from the surrounding area participate in the “mussels in the classroom” program. this provides teachers with their classroom’s own recirculating aquaculture system and some juvenile mussels. with this, students are able to engage first-hand with measuring mussels and monitoring water quality. 

the hatchery also runs a “mussels in the field” program located at the audubon discovery center, which provides youth from six nearby school districts with similar hands-on interactions, as well as introduces students to blue-green infrastructure. once a month, the discovery center also hosts “mussel maniacs” where adults can participate in similar field work and connect with other conservation enthusiasts. 

rebuilding a population of workhorse filterers

since the hatchery opened in 2017, they have consistently propagated around 10,000 mussels each year. the fww mussel hatchery strays away from what these types of aquatic field stations often aim to do, which is to focus on restoring endangered native populations. instead, the hatchery is working to build up common species that once thrived in the schuylkill prior to industrial development, which could lead in local efforts to purify water sources for philadelphians. 

in the wild, mussels have a few main ways of propagating, but scientists in the hatchery lab do these manually. this past year, the hatchery achieved a new personal record of the highest number of successful propagations with 20,000 mussels. so far this year, the hatchery more than doubled their yearly propagation numbers with just two inoculation trials. they also performed their first study to determine the rate at which two species of freshwater mussels could remove pollutants. 

looking ahead, the results will be used to determine how mussels can work as a complement to traditional pollution control technologies. with all these new milestones, heffernan says, “we have made a lot of strides in a short period of time.

why cleaner wrasses are so important

cleaner wrasses like clewra are vital for the health of coral reefs, ecosystems that are currently under threat. coral reefs are fragile and sensitive to changes in the environment, and climate change has led to widespread coral bleaching. many reefs across the indo-pacific are struggling and cleaner wrasses are part of the solution. they help maintain the balance by keeping the reef fish healthy, which in turn, helps preserve the reef ecosystem.

this is why my research focuses on cleaner wrasses like clewra. as a student at the university of hawai’i studying marine biology, i wanted to understand how their social behavior and cognitive abilities contribute to the reef’s health, especially in areas still relatively unaffected by coral bleaching. by studying these cleaner wrasses, we can compare their behavior and intelligence across different regions, providing insight into how environmental changes might impact the species in the future.

how cleaner wrasses maintain reef health

with her elegant, shiny purple, blue, and yellow body, clewra darts around the reef like a little underwater superhero. her mission is to clean her clients of annoying parasites and dead skin, leaving them refreshed and rejuvenated.

clewra’s unique talent lies in her ability to perform various gestures to attract and calm her clients. she trembles with excitement to signal she’s ready to clean, her flapping fins creating an irresistible invitation. some clients even say her touch is like a gentle massage, building trust and bonding. her “tactile stimulation” helps her clients relax, similar to a relaxing spa experience for humans.

cleaner wrasses don’t just clean fish for the sake of hygiene, they play a crucial role in the reef’s social structure. their cleaning services foster a sense of community where fish of all sizes and species line up to get their parasites removed. even predators like groupers and barracudas show up at the cleaning stations and wait patiently for their turn, demonstrating how cleaner wrasses contribute to peace and cooperation among marine life.

this unique social behavior creates a symbiotic relationship that benefits everyone. cleaner wrasses are essential because they help prevent diseases by keeping fish free of parasites, ensuring the survival of both the fish and the reef ecosystem. this, in turn, impacts human coastal communities, which rely on healthy reefs for resources and protection from storm surges.

clewra’s intelligence and skill

what makes clewra and others of her species truly fascinating is their intelligence. cleaner wrasses are among the few fish species that can recognize themselves in mirrors, a sign of self-awareness, a rare trait among fish. clewra, in particular, has a remarkable ability to remember individual clients and their cleaning preferences. some cleaner wrasses cheat by nibbling at the protective mucus of their clients instead of just eating the parasites, but clewra is honest and trustworthy. her clients keep coming back because they know she does her job well.

researchers have found that the social intelligence of cleaner wrasses may even contribute to the development of their cognitive abilities. fish that interact with these cleaners must adapt and respond to social cues, making the reef a place of constant learning and communication. my research aims to delve deeper into this intelligence by conducting behavioral and cognitive tests on cleaner wrasses like clewra.

the ecosystem’s hidden heroes

cleaner wrasses like clewra are essential for more than just maintaining cleanliness. their role in preventing disease and infection ensures the overall health of the reef. without them, the balance of life on the reef could collapse, causing a ripple effect that would impact both marine life and human coastal communities.

rapid ocean warming poses existential challenges to maine’s largest commercial fishery. stress induced by rising temperatures can make lobsters more susceptible to shell disease, compromising their ability to reproduce successfully. in warmer waters, tiny copepods eaten by larval lobsters are growing smaller and shifting their seasonal migration patterns. this results in less nutritious food for baby lobsters, greater mismatch between lobster larvae release and food availability, and fewer juveniles surviving into adulthood. in the wake of these changes, experts predict that lobsters will increasingly seek refuge in colder, deeper waters and migrate northward toward canada. 

transcript: generally, we are seeing a pattern of lobster shifting further into the northeast region of the gulf of maine into cooler, deeper waters during certain life stages. but, that doesn’t necessarily imply that they’ve all migrated there or moved or marched up from southern new england. it will be more about redistribution of where lobsters are more available, which relates to how readily some people compared to others can capitalize on those different changes. and perhaps abundances returning to early or mid-2000s landing levels rather than staying at that peak that we have known in more recent years.

kat maltby, ph.d., postdoctoral research associate in the integrated systems ecology lab at the gulf of maine research institute (gmri).

notably, ocean warming has supported a boom in maine’s lobster industry and a bust in southern new england. in the gulf of maine, temperatures have become optimal for lobster reproduction and species range shifts have contributed to record commercial catch. yet, experts predict that rapid warming will only exacerbate the volatility of maine’s lobster industry, posing novel challenges to fishers and business owners to adapt alongside the shifting crustaceans.

on the frontlines: lobster fishers

ivan bly started lobstering in midcoast maine when he was young. today, he hauls commercial traps from the iris irene, a boat named after his grandmother, irene, and 12-year-old daughter, iris. alongside her father, iris has been lobstering her entire life. “we’ve had her out here before she remembered. we used to put her in a lobster crate,” bly said.

bly lobsters out of tenants harbor, where his state commercial fishing license allows him 800 traps within an established fishing zone. state and federal licenses are coveted and scarce in maine, requiring extensive apprenticeship, extended processing times, and expensive permitting costs. those born into the lobster industry are entering increasingly precarious waters, where rigid rules and regulations preoccupy fishers and lack adaptive measures for climate impacts.

bly recognizes ocean warming and its contribution to maine’s lobster boom. he also knows the challenges and costs of fishing in deeper waters. “when you go further out, it costs more money, and it’s a bigger risk. you need bigger rope, heavier, bigger traps,” he said.

yet, faced with the annual volatility of a dynamic industry, his anxieties are resigned to the short-term: “i think we’ll kill the industry with chemicals and nonsense before that. warming is the least of my concerns. when the water warms up that much, i’ll be long gone.” for bly, “nonsense” includes the environmental and economic costs of chemical pollution, offshore wind development, and inconsistent rope and trap regulations for north atlantic right whale protection.

contributing to bly’s focus on pollution and regulation is the rigid territoriality built into the culture and permitting of the lobster industry. while a commercial fisher can move their traps within a permitted zone, they risk retaliation and violence from encroaching on another fisher’s territory.

according to bly, “you’d be welcomed with shotguns and knife blades” if you messed with another’s traps. notably, a state license prohibits fishing in federal waters further offshore and can rarely be transferred to a different zone within state waters.

in this rigid framework, fishers like bly cannot follow lobsters into northern, deeper waters beyond where their permit allows. “the fishing grounds do move. different areas have had great fishing and hopefully, we get our turn. but, you gotta fish where you live,” bly said.

from sea to table: lobster shacks

in maine’s coastal economy, changes in the water directly affect livelihoods on land. in bar harbor, patti staples is the owner and manager of the happy clam shack, where hand-picked meat is enjoyed by consumers in iconic lobster rolls.

since 2015, staples has operated a sea-to-table business that values quality over quantity. to do so, she buys catch directly from local fishers and picks the lobster meat in-shack each morning. having experienced increased costs, decreased tourism, and supply chain shortages during the pandemic, staples sees ocean warming as another existential threat to her business and local suppliers.

“if they don’t have their product, we don’t have their product, and the families don’t have their product. if the gulf doesn’t stop warming up, they’re going to crawl into canada,” she said.

profit and catch in the lobster industry fluctuate with consumer demand and market price. for instance, in 2023, maine experienced its lowest lobster haul in 15 years, as inflated fuel and bait costs disincentivized fishers to get on the water. yet, the second-highest price ever recorded ($4.95 per pound) contributed to a noticeable rebound from lower profits in 2022.

ocean warming will only exacerbate these unpredictable boom and bust cycles. as warming decreases regional productivity and increases operational costs, per-pound prices will reflect the increased effort and resources needed for fishing in deeper waters. as a result, staples anticipates higher costs for herself and her customers. 

transcript: unfortunately, we will see the prices go up. we won’t see as many businesses like our lobster pound being able to sustain if we don’t have a product. if it gets too costly, a lot of people — the families we want here to enjoy our lobster — won’t be able to afford it. and if our fisherman aren’t catching their product and they are paying all this money for their sternmen, their gas, their bait, how are they going to be able to sustain also? it’s scary. we don’t want to see our product leave.

what’s next for maine’s warming waters and its lobsters?

since ocean warming intersects with the economic and regulatory challenges facing fishers like bly and business owners like staples, climate adaptation is an opportunity to build a more resilient, productive, and profitable industry. at the gulf of maine research institute (gmri), kat maltby, ph.d., studies the social resilience of imperiled fisheries to inform adaptive planning in maine’s lobster industry. to her, adapting to warming waters requires a holistic management approach in collaboration with industry, government, and the scientific community.

transcript: there’s an opportunity for us to be more integrated in joining efforts to think more holistically about supporting resilience. when we talk about adaptation strategies, we need to talk about that in the context of all the other issues the industry is concerned about and think holistically about the future needs of the fishery and the industry together. just thinking about climate change in a silo risks maladaptive strategies or implementing strategies and solutions that might not work as effectively or successfully because there are other drivers of change that haven’t been considered.

kat maltby, ph. d., gulf of maine research institute

for fishers, she emphasizes empowering a sense of agency over diverse livelihood options, including:

• directly changing fishing practices or shifting fishing grounds, if possible.
• moving into direct sales with consumers to increase the value of lobster products. 
• diversifying into other fisheries or marine occupations like aquaculture and kelp farming.  
• participating in science-industry partnerships and management decision-making at the state, regional, and federal levels.

maltby upholds that the burden of adaptation should not be on fishers alone. she contends that all levels of the industry must adapt simultaneously. this includes changing processing and handling capacities in the supply chain in order to enable diversification into other fisheries.

she also recommends maintaining working waterfronts that protect coastal properties for commercial fishing and aquaculture use. lastly, maltby supports the creation of more flexible permitting structures that incorporate information and decision-making from lobster fishers like bly.

while lobster redistribution is inevitable in maine’s warming waters, fishers already follow strict sustainable fishing standards that support stable, resilient lobster populations in the gulf of maine. these practices include notching the tails of egg-bearing females and measuring catch to ensure small juveniles and large, reproducing lobsters remain in the water.

transcript: ivan: is it a boy or girl? iris: girl. ivan: does it have a v-notch? eggs?

a gmri study found that the lack of protections on larger reproductive lobsters in southern new england made the population less resilient to warmer waters, contributing to its collapse. on the contrary, conservation measures in the gulf of maine supported a lobster boom and can mitigate expected productivity declines. given maine’s lobster fishery is already resilient due to sustainable management, maltby sees hope and opportunity for the broader industry to operate in warming waters. “it’s not all doom and gloom. this really provides us an opportunity to think about the kinds of futures we want.”

transcript: climate change is a very big risk and has a lot of impacts now and will continue to have for many coastal communities in maine. but, it is not all doom and gloom. this provides an opportunity for us to think about the kind of futures that we want and think about the processes that allow us to get there. drawing on more innovative and creative ideas and solutions. really connecting people who haven’t necessarily been able to exchange ideas and information before. it doesn’t have to be such a gloom-and-doom narrative.

climate change is threatening people globally, but it also presents business opportunities through innovation and sustainability, said bea perez, global chief communications, sustainability, and strategic partnerships officer at coca-cola.

perez addressed hundreds of global influencers and upcoming mba entrepreneurs at northwestern university’s kellogg climate conference this spring. perez and other corporate leaders advocated for sustainability during the impending climate crisis linked to rising temperatures, economic instability, weather disasters and water insecurity. 

the conference drew on expertise from the energy, transportation, agriculture, food, finance and other sectors to leverage solutions, such as the generating enough electricity and parts to transition to electric fleets for corporate shipping and mass transit. 

an anticipated $1.3 trillion in investment will be needed to innovate and curb climate pain points companies have inflamed in recent years, turning the spotlight on the sustainability leaders globally. 

perez focused on coca-cola’s recent sustainability efforts and errors at the conference hosted by the kellogg school of management and northwestern’s paula m. trienens institute of sustainability and energy. 

evaluating big business’s responsibility to mitigate climate change

kellogg brought corporate leaders from companies including exxon-mobil, invenergy, and general motors under one roof to educate and prepare future business leaders to prioritize sustainability and innovation. 

there’s two things everybody should understand about climate — where do greenhouse gasses come from and how are industries and companies following through on climate mitigation goals, said meghan busse, associate professor of strategy at the kellogg school of management. 

perez combined the outlook for commercial profitability and sustainability to evaluate what roles the fortune 500 company plays in prioritizing the climate as a key strategy in decisions, not just an offshoot program. 

her theme was accountability — owning up to coca-cola’s mistakes and reimagining the company’s more recent role in mitigating climate change. some steps included changing bottle design and water conservation. 

“don’t you think we have a responsibility as a business to manage those resources [water and carbon] and do better?” perez said.

taking accountability

by reducing the amount of carbon used to produce a singular coca cola product by 25%, perez said the company found a loophole when they first tried to focus on sustainability. 

their per unit carbon usage was down, but since business was growing, it let coca-cola grow their carbon emissions in “absolute terms,” perez said. 

“we made a mistake,” perez said. “and so just as any smart business group would do… we had to reset the plan.”

in other words, coca-cola needed to establish new targets that held all aspects of their business accountable in lowering their carbon emissions – and not just their production line. 

perez also recognized the role fortune 500 companies play in restoring resources like water. 

“you can’t have a conversation about climate, unless you talk about water,” perez said.  

coca-cola established three goals hoping to restore all the water they use for production globally: using 100% regenerative water across 175 facilities facing “high water stress,” improving 60 watersheds’ health, and returning two trillion liters of water to communities. 

in 2021, coca-cola introduced regenerative water as a metric for achieving their sustainability goals. the concept includes reducing, reusing, recycling and replenishing water to communities for nature and other stakeholders to use, according to their 2021 sustainability report. 

perez’s talk put more responsibility on corporations to work on climate change mitigation, rather than falling on the consumer. 

“water is a human right… a lot of places in developed countries don’t have water regulation. if you go into emerging markets, they typically do. and so how do you make sure there’s [a] great water policy in place for people and for society?”

emphasizing community

perez said that between 2018 to 2022, there were only 18 days, on average, between every billion-dollar disaster, compared to 82 days in the 1980s. 

coca-cola shifted its value proposition from getting communities to spend money on their products to investing back into the communities where resources are acquired from.

“if you don’t have strong communities, you don’t have businesses,” perez said. 

“water still will always be number one, but it cuts in many slices… some people say, ‘we saw you met your target five years ahead of schedule, so what are you doing today?’” perez said. 

she said coca-cola is now working to replenish 100% of the water it uses. 

room for improvement

despite getting ahead of their target, coca-cola falls short compared to the company’s leading food and beverage competitor: pepsico.

pepsico used 1.4 liters of water per liter of beverage product produced, according to their water stewardship approach, which is 0.39 liters less than of coca-cola’s usage in their latest business and sustainability report. 

perez also spoke about the importance of independent auditing for environmental, social and governmental reporting. 

“imagine if it were just coca-cola saying, ‘hey, we did this,’” perez said. “do you think you would believe me? this is a little bit like a conflict of interest, right?” 

esg reporting involves publicly disclosing information about environmental, social and governmental business operations, according to the corporate governance institute. 

coca-cola made the switch to sustainability report auditing through ernst and young, a multinational professional services company, in 2015. 

coca-cola was one of the first in the pack, since only 2% of fortune 500 companies started esg reporting back then, perez said. 

perez urged audience members to look up coca-cola’s business and sustainability reports, which replaced the reports that were originally only geared towards quantifying how well the company was reaching sustainability targets.   

the transition came after coca-cola realized it was sending “unintended signals” that they had two separate reports, perez said. 

“it would look as if it [sustainability] wasn’t important to our business,” perez said. “frankly, you saw throughout those charts how important it [sustainability] is to our business].”

a data-informed approach

coca-cola incorporates a next-generation data platform to track and manage progress against esg metrics and has abided by the sustainability accounting standards board standards since 2020, according to their 2021 reporting frameworks and sustainable development goals. 

the company focuses on water leadership, packaging, climate, sustainable agriculture and communities in their esg report, according to their 2022 business and sustainability report. 

“we integrated the data,” perez said. “we made sure that we have the same standard that we have in our financial reporting as we have in here — [the esg report].”

currently, companies are only required to report scope 1 and scope 2 criteria, which involve reporting greenhouse gas emissions from sources an organization directly owns and from indirect energy sources the company has purchased, according to the securities and exchange commission. 

scope 3, emissions that the company does not produce by itself and are not from the companies’ assets, and water consumption reporting are still not required by the sec.

navigating the future of esg reporting

currently, coca-cola’s reporting has been voluntary in the u.s., so accountability hasn’t come at a penalty cost, yet. 

but what happens when the sec enforces mandatory esg reporting?

on march 6, the sec adopted rules to “enhance and standardize climate-related disclosures by public companies,” according to the sec’s enhancement and standardization of climate-related disclosures for investors. 

while declaring water-usage was proposed as an inclusion  for the final rule, it was ultimately axed to simplify requirements and prevent putting a “topical focus” on any one climate-related disclosure, according to the disclosure. 

coca-cola has already begun anticipating the sec’s future moves towards making sustainability reporting mandatory.  

 perez said she tells her team to consider how much voluntary reporting they’re doing that could impact mandatory reporting in the future. 

“if you report work you’re really not doing, with the sec rules, you’re going to have personal fines to executives, criminal penalties potentially. so the stakes are higher,” perez said. 

according to the united nations, in 2022, two billion people worldwide did not have access to safe drinking water, and only 0.5 percent of water on the planet was usable freshwater. to help combat this water insecurity, we use desalination, a process implemented globally to increase the amount of fresh water available by removing salt and other pollutants from seawater and brackish water. desalination, while an effective method of producing freshwater, is not without its challenges.

the process produces brine, a waste product of highly concentrated salt water. but what if this waste product could be used to create something positive?

elizabeth north, ph.d., a scientist and professor at the university of maryland center for environmental science, and her team of researchers are currently developing a biomanufacturing process that uses brine to produce calcium carbonate, a chemical compound needed in various industries.

this story was produced as part of the planet forward summer seminar in multimedia storytelling.

evanston, il – a team of northwestern university climate scientists teleport back in time with naturally preserved records they extract as cylindrical cores of lake sediment.

the sediment layers in the cores open the way to time travel through climate changes over the past 20,000 years. third-year ph.d. students bailey nash and aidan burdick analyze cellulose and carbonate materials, respectively, found in sediment over time to better understand how we can prepare for accelerating human-caused climate change now and moving forward.

after carefully extracting the sediment cores from lakes in greenland and the midwestern united states, the team brings them back to professor yarrow axford’s quaternary sediment laboratory on campus for the laborious analysis.

“this research is very iterative,” burdick said. “you do one thing, you learn something from it, you move on to the next, and eventually, you build a body of knowledge over time.”

burdick focuses his research on the midwest, looking at sediment deposits from lakes around the region. by building a record of illinois’s hydroclimate, his research will help serve illinois and midwest city officials by improving water resource management, among other applications.

“we can already see clear evidence of way more sediment being deposited after europeans arrived [in illinois], probably because of agriculture and things like that,” burdick said. “i’m using this core to try to understand lake chemistry in the context of carbonate materials. we can use the chemical variations in the minerals to see how the local hydroclimate has changed over time.”

while burdick is focused on the midwest and great lakes, nash noted that much of the team’s work takes them to the arctic, specifically in south greenland where deglaciation began around 15,000 years ago driven by rising air temperatures. this upcoming summer, nash will be visiting the community of narsaq to conduct her research.

“one of the primary questions that i’m trying to address through my ph.d. work is how arctic lakes respond [to climate change], especially in regard to their lake levels,” nash said. “so, did lake levels rise or fall during periods of past warmth? and what does that mean for arctic communities that rely on these similar arctic lakes today as a municipal water source?”

after extracting cellulose from ancient plant matter in the sediment, nash uses a mass spectrometer to analyze cellulose isotopes over time. cellulose is the most abundant biopolymer on earth, and the isotopic signature of cellulose that gets preserved in geologic materials can serve as a record of differing past climate conditions.

“these isotopic compositions can say a lot about whether lake level was higher or lower in the past,” nash said, “or if the environment was warmer or colder than it is today — those pieces of the climate story.”

it’s not well understood whether lake levels in the arctic will rise or fall in a warming world, but the risk of lakes either flooding or drying up is a climate concern across the world. thus, nash feels this must be investigated. because their work takes place on indigenous land, nash also emphasized the focus their group has on community engagement and performing scientific research respectfully and ethically.

“these communities have a very complicated relationship with western science in general and the people that we represent when we come back,” nash said, “so it really takes time and open-mindedness entering these communities and building trust, honestly, and laying the foundation of mutual respect and understanding.”

in a field dominated by men, nash gravitated towards axford’s lab not only because of her specialization on arctic paleoclimate research but specifically after reading axford’s science article titled ‘thanks to the glass ceiling breakers,’ outlining her experiences as a woman in stem.

“today, i’m living my dream,” axford wrote in her 2016 article, “and yet, despite how far science has come… i have lost track of how many times i’ve met a colleague for the first time and been told, ‘i’ve read your papers. i thought you were a man!’”

“i was just blown away by everything she had to say [in the article],” nash said. “i thought she seemed like such an incredibly strong glass ceiling-breaking scientist… the arctic is the most rapidly warming region on the planet today, which poses a very immediate concern for climate scientists. i was very compelled by the argument that studying past and current arctic climate change impacts can help us better understand and prepare for current and future climate change impacts globally.”

a century ago, tens of thousands of people would swim in its waters on hot summer days. however, since the 1970s, swimming in the river has been illegal due to pollution concerns, and advocates now argue that it is time to change what they call archaic laws.

in 1965, president lyndon b. johnson labeled the potomac a “national disgrace” while also championing its restoration. the clean water act of 1972 aimed to make all american waterways fishable and swimmable, and subsequent efforts, such as dc water’s clean rivers project, have made significant strides in improving water quality. local government officials have expressed optimism that some parts of the potomac will be open for swimming by 2030.

“the ban” focuses on the complex history pertaining to swimming in the potomac river and the debates on how to open it up for swimming again. dean naujoks, a potomac riverkeeper, claims that certain parts of the potomac are currently safe for swimming up to 90 percent of the time. denis crean, an open water swimmer, even defies the ban and runs programs promoting the use of the river for wellness practices such as “wim hof techniques” to address mental and physical health issues. despite push backs from law enforcement, he continues to advocate for change. meanwhile, jonathan champion, the associate director of the water quality division in the d.c. department of energy and environment, expresses cautious optimism about lifting the ban, but emphasizes the need for continued testing, which is often hampered by bureaucratic constraints and budget cuts.

decades of prohibition have left a lingering perception of the river as dirty and unsafe for swimming, despite significant improvements in water quality. the lack of awareness about such advancements, coupled with the enduring stigma of pollution, may deter some people from embracing the idea of swimming in the potomac once more. as discussions about reopening the potomac for those who wish to swim in its waters intensifies, addressing concerns and effectively communicating the strides made in environmental restoration will be crucial in building public confidence.

it’s important to note how privileged i am to have both grown up by the beach and to now live in a place where access to clean water is never in question. but as global temperatures rise, water scarcity is becoming more widespread and increasingly on my mind. 

as a 21-year-old college student stumbling through balancing school, work, sports, and a social schedule — the idea of making a lifestyle change felt daunting to me. despite my concerns about climate change and conservation, i felt helpless in my ability to make a meaningful difference. however, the first step on the journey to using less water is understanding the role water is already playing in your daily life. this knowledge empowered me to start taking action.

the first step i took was locating a resource that could explain my water footprint, or the amount of gallons of water i was using each day. this online resource was simple to access and understand, prompting me with a quick five minute quiz and then breaking down my results. my water footprint was impacted in ways that i did not expect by the food that i eat and the commutes i make. i began to get curious about other places that water was hiding in my daily life, hoping it would lead me to some answers about easy ways that i could make a change. 

below were some of the most surprising stats and facts:

impacts from food

about 25% of all freshwater consumed annually in the u.s. is associated with discarded food.

armed with this new knowledge, i made a commitment to begin conserving water in simple ways through changes that i found barely noticeable. the statistic about food waste was the easiest place to start so over the last several weeks i have made a conscious effort to only buy groceries that i know i will use and to make sure my fridge is empty before i restock.

impacts from travel

gasoline and oil consumption are tightly linked with water usage due to the demands of the oil refining process.

my water conservation journey has conveniently corresponded with the return of warm weather to d.c. which has made my commitment to walking as a primary transportation method all the more enjoyable- less ubers and more sunshine! 

 

impacts from electricity

electricity consumption factors into your water footprint because of powerplants’ reliance on water.

lastly, as a staunch hater of overhead lighting, i had a bad habit of leaving my lamps on when i left the house. i’ve tried to remedy this by taking an extra step in the morning to unplug them and save a little bit of energy.

 

even if you’re not ready to make big lifestyle changes like cutting out red meat or biking to work, being aware of your water footprint is a great way to start thinking about conservation. never underestimate how far the little things can go.
