Author’s positionality
Before continuing to the briefing, I would like to recognize the privilege I have of being able to have access to the resources that enable me to write a piece of work such as this one. This briefing is focused on being for the people and them only. I believe that even though communities must sometimes rely on governmental bodies and NGOs to reach sustainability goals, social inclusion is a crucial aspect that is overlooked during processes. Communities, both rural and urban, have the potential to be localized routes to sustainability. Hopefully with a substantial amount of participation in practices and policy, at the personal level that is, others will take notice leading to a larger social change at the regional, domestic, and national level. It must be recognized that this paper does not aim to direct state-run actions but merely plant the seeds of change where it is so desperately needed.
I recognize Central Harlem as being one of these areas, one that suffers from the extreme effects of climate change. Climate change is in most cases a silent but deadly characteristic of the world we live in. Rising sea levels and changing weather patterns pose threats to the natural environment and the livelihoods of billions. It should be prefaced that I do not intend to state that climate change can be solved by the community of Central Harlem. I would like to avoid creating a feeling of extreme pressure on my chosen community by stating this is simply not the case and remains true for any group of people. It must be approached by billions around the world, a nod back to how communities could be paths to localized and large-scale transformation. A prime example of such a tactic were the community reliant initiatives to combat Covid-19 in the past 4 years.
Nineteen years of my life I spent growing up just a short walk away from Central Harlem and by frequenting the area for sport, I feel that I must give back to the community. By juxtaposing my former neighborhood, the Upper West Side, with it, I notice the major differences in the area economically and resource wise. Creating cool neighborhoods is a function of these two things. How could two areas that are so close to each other be so different? This is my main question and one that led me to share my thoughts on a personal level about how to mitigate the health effects of rising temperatures. This inequality is emphasized even more so where I currently live in a rural setting which experiences coastal breezes allowing homes and people to remain at lower temperatures even during heat events. Being a student allows me to approach this problem in as simple terms as possible backed by academia. Despite this I am still speaking from a privileged point of view. There may be a stark difference in knowledge and experience between me and those who reside in Central Harlem. Therefore, I acknowledge that my suggestions may be limited by this lack of familiarity. I wish to help those struggling with health effects and underlying diagnoses to ensure that heat does not affect their daily lives. I believe that neighborhoods of New York City have a strong willingness to come together and help each other no matter who they might be. Central Harlem and other communities can unlock a potential of civic participation which is subdued by a lack of power, education, greed, fear, and mistrust (Chatterton, 2019). I have full confidence in the abilities of Central Harlem’s population to create a healthier environment for all. Additionally, my suggestions are not solely for one demographic. I wish that every gender, age, race, and ethnicity may consider what I say in the following paragraphs with no third-party intervention.
Community
Considering meeting global sustainability goals, new ways to face the obstacles of mass urbanism using urban justice must be considered, while remembering that a city is a space with history and people should have the right to remain in the spot they currently reside in. Cities have been able to outlive multiple governing bodies and radical social transformation (Sassen, 2018). New York City is deeply rooted in its own history with ties back to the native populations that roamed prior to the colonization of European powers. Just like its fellow colonial cities of Philadelphia, Boston, and Charlotte, it began to form into an area that revolved around capital, trade, and dense living. Today it offers to many a deep sense of home, culture, diversity, and opportunity. The almost 8.9 million people (United States Census, 2020) are crammed into Manhattan, Queens, Brooklyn, The Bronx, and Staten Island. Manhattan is home to roughly 1.7 million residents in the metropolitan area, making it the third most populous borough (United States Census, 2020). Through the perception of media, most may assume the heart of Manhattan lies near Times Square or Soho. Although these areas may be significant in that they experience elevated levels of foot traffic and economic prosperity, Manhattan and its neighboring boroughs are filled with tucked away communities that pose their own charm.
Central Harlem is one of many that offers attractions, good food, good people, and an overarching sense of community, spanning from Harlem River to the north, Central Park to the south, Fordham Cliffs to the west, and Fifth Avenue to the east (NYC Department of SBS, 2019). It is a product of a mass immigration pre–World War I, both domestically from other parts of New York City as well as abroad from the Caribbean into newly built tenements predominantly owned by white people (Columbia University, 2024). By the 20’s, the Harlem Renaissance’s artistic expression took over as the beating heart of the area (Grunwald, 1999). The people of Harlem were hit hard by the crash of 1929 leading to a cascading disparity both economically and socially leading to later riots in the 60’s and 70’s combined with the crack and AIDS epidemics in the 80’s (Foster, 2003). The effects of these historical events have been rooted in the space of Central Harlem and are being felt by the population today. Central Harlem is home to 138,953 people, 45.8% of which identified as Black, 28.2% as Latino, 14.4% as White, and 4.5% as Asian (NYU Furman Center, 2022). Diversity offers an inclusive neighborhood that prospers of the concept of community building. As of a community health survey conducted in 2018, 82% of adults reported that they were willing to help each other compared to a citywide percentage of 78% (NYC Health, 2024). Despite this Central Harlem seems to continue to struggle both economically and socially. 21% of residents live in poverty and 9% are unemployed compared to the 13% and 5% averages in the Manhattan as of 2019 (NYC Health, 2024). The median household income as of 2022 was $51,990, about $25000 less than the citywide average (NYU Furman Center, 2022). These imbalances are why I want to address this community specifically. They have the right social makeup but lack the economic fortitude to move forward with action to mitigate the health effects that the urban heat island may have on them. By catering my suggestions to a level that is attainable, the chances of them being adapted are higher and possibly looked at as being friendly to the population of Central Harlem. I would like to resonate to my community Chattertron’s (2019) statement that we must break down larger concepts and challenges into “manageable chunks and simply try things out on a small scale” as there is “no workable blueprint for unlocking sustainable urban futures” (p.115).
Health Effects of the Urban Heat Island Effect
As global temperatures rise, many metropolises are faced with harsh heat conditions that can lead to serious health effects or loss of life. The urban heart island effect (UHI) is when urban areas, like Manhattan, become ‘islands’ of higher temperatures relative to surrounding rural areas (EPA, 2024). Although the acceleration of the UHI has become more relevant given the state of our world, the concept has been termed for much longer than expected. It was first observed and recorded in 1833 in London and has since been measured in cities around the world (Heavside et al., 2017). This ‘heat accumulation phenomenon’ is caused by a multitude of factors especially human activity (Yang et al., 2016). Decisions on building geometry and surface materials can increase temperatures in cities (Heaviside et al., 2017), most of which are filled with high rises and buildings that lack the proper facets to remain cool. If the physical space remains at a tolerable temperature, then its inhabitants will be less susceptible to the threats of heat. Air pollution emitted from vehicles like cars, buses, and taxis also contributes to the UHI as well as using cooling systems like air conditioners (Nuruzzaman, 2015). These devices pump hot air out when in use. The built environment also affects the amount of heat in cities retain mainly in a passive manner. A lack of wind caused by large structures causes hot air to linger and short-wave radiation to constantly bounce around (Kleerkoper et al., 2012). Again, we can see how places like Manhattan or London, with their many glass skyscrapers create perfect conditions for an anomaly such as the urban canopy where multiple layers of buildings trap heat (Nurruzzaman, 2015). While most of the effects are experienced during the day, heat release can happen at night. The nature of concrete, the material most notably used in cities to build sidewalks, allows for solar heat to remain trapped for longer than soil, causing an extended release overnight (Parker, 2010). It is important to point out the way in which anthropogenic heat release only emphasizes the effects. In addition to the causes above, certain industries like construction require for energy to power machinery and construction vehicles that can lead to an immense rush of heat release throughout the year. In 2023 it was predicted that $83 billion was spent on building projects with an estimated 66 million gross square feet added to the metropolitan area of New York City (New York Building Foundation, 2023) making it the most constructed region in the entire United States (New York Post, 2024). Manhattan alone is set to have almost 3000 new apartment units available in 2024 (ibid). The community of Central Harlem is being setup for failure from a health standpoint. Expanding on how members are being affected it by from this point of view is crucial to why it has been chosen for this briefing.
The heat vulnerability index for both north and south-Central Harlem was ranked a 5 (Figure 1), the highest number on the scale (NYC Environment and Health, 2023). The ranking shows the risk of community level impacts such as deaths caused by extreme heat and is constituted by data like surface temperature, green space, accessibility to air conditioning, and median income (ibid). In 2018 community members had to battle the average daytime surface temperature of 98.35 degrees Fahrenheit during the summer in Central Harlem (NYC Health and Environment, 2018). Before proceeding it should be noted that this briefing does not intend to substitute people with numbers when presenting statistical values. Numerical values are important to the fact that this paper is trying to capture how severe the health effects of the UHI have been and will continue to be without proper intervention. With that being said, the human body is a complex organism that in extreme exterior circumstances will begin to deteriorate. During the UHI effect as the air and ground temperatures increase, heat begins to rise causing the human body to exert more energy to stay cool. The amount of heat stored in the body is affected in different ways which include lack of ability to rid oneself of heat generated from metabolic processes, clothing, and excess heat stress from environmental conditions (WHO, 2024). If the body reaches over 41 degrees Celsius, heat stroke will most likely ensue along with ‘fever, hot and dry skin, rapid pulse and sometimes progresses to delirium and coma’ (Shahmohamadi et al., 2012, 67).
Central Harlem has a higher concentration of ethnic minorities specifically Black New Yorkers (NYU Furman Center, 2022). This population faced around 1.2 deaths per million compared to the 0.5 deaths per million of White New Yorkers from 2013 to 2022 during warmer months (May to September) (NYC Environment and Health, 2022). The Hispanic and Latino communities also faced a slightly higher rate of 0.8 death per million (ibid). These two groups lack the most resources to mitigate heat related stress hence why their number of deaths were greater. The effects of heat on pre-existing health conditions must also be considered as underlying conditions can be emphasized with extreme heat specifically cardiovascular issues, diabetes, and asthma (Shahmohamadi et al., 2011). The obesity rate of Central Harlem was 35%, which is higher than that of the NYC area at 25%, while 7% of adults were diagnosed with diabetes, and 31% of residents reported have hypertension commonly known as high blood pressure (NYC Health, 2020). Adults with asthma (including Morningside Heights) was 15.9% in 2020 and in 2022 there were 182.3 asthma emergency visits per 10,000 children and 179.1 visit per 10,000 adults (NYC Environment and Health, 2022). Asthma is attributed to several factors including inadequate housing as well as placement due to socio-economic conditions near pollutants (Rosenbaum, 2008). Central Harlem needs a plan to slow the health affects the urban heat island effect has on them. Community involvement is a way to break the cycle of loss of life and improve wellbeing.

Recommendations
Utilizing Space: Green Areas and Community Centers
My first recommendation that I have for the community is utilizing urban green spaces and community building spaces for both cooling affects in a physiological and psychological way. As mentioned in the ‘Community’ paragraph, Central Harlem suffers mainly from a lack of economic prosperity. UHI tends to be more intense in areas that are lacking from a socio-economic standpoint and there is provided evidence that areas with more vegetation tend to be in more affluent areas hence remaining cooler (Heaviside et al., 2017). Parks and urban green spaces can cool down large areas by providing copious amounts of shade (Kleerkoper et al., 2012). Despite being at a disadvantage from a heat standpoint, Central Harlem has a plethora of parks where many can take refugee from extreme temperatures while simultaneously receiving the positive effects of nature connectedness. Jackie Robinson Park, Marcus Garvey Park, St Nicholas Park, and Morningside Park are just a few of the many available sites that would provide the needed shade. Together these provide alone an area of roughly 85 acres which consists of around 40% of open space in Harlem (NYC Department of Parks & Recreation, 2024). Despite this, parks which are in predominantly non-white neighborhoods are half the size of parks in neighborhoods with a higher white population and tend to have a greater amount of people within them (Urofsky and Parks, 2020). A solution to this problem would be creating a deeper relationship with community groups that are associated with each different park. By approaching these collectives’, newcomers have the potential to engage more as those running such programs will be similar in socio-economic stature thus appearing less intimidating than say the NYC Parks Service themselves. Friends of St. Nicholas Park for example consists of only roughly 50 group members and is aimed at revitalizing and maintaining the park while also organizing public events and providing volunteer work for those who are interested (NYC Department of Park & Recreation, 2024). The people of Central Harlem can gain two main things out programs like this. The first being the ability to contribute to making spaces more welcoming for others so that they may reap the benefits of parks which include being able to keep cool and improve psychological and physiological health. Park space has been connected to not only more physical activity but also the reduction of illnesses and diseases (Cohen et al., 2022) like the ones experience by a percentage of Central Harlem residents. Simultaneously, mental health of residents which is ultimately stressed by high temperatures can be subdued with nature. The second would be crafting the ability to engage other members so that parks become a habitual part of residents in Central Harlem thus creating an improved environment and an option to escape from the concrete convection oven.
Along with parks, community spaces such as churches, public schools and athletic centers have the potential to act as cooling centers for those who lack the proper facilities in their homes to create comfortable living environments. As of 2017, only 82% of households (4 out of 5) have working air conditioning compared to the Manhattan percentage of 93% (NYC Health, 2017). This number makes sense if you turn back to the statistic that most heat related deaths occur amongst the Black and Latino populations of NYC. Most heat strokes occur in homes that lack air conditioning most of which are occupied in Central Harlem by these two demographics. There are 86 listed churches on the NYC Gov website that is accessible (NYC Gov, 2024). The list provides the name of the church, its address, telephone number and some with an email, and name of the pastor, bishop, or reverend (ibid). This list could be extremely important and can be utilized by community to reach and create spaces open to all who suffer from the absence of air conditioning. Given the physical setup of churches with many of them being open spaces with high ceilings, air ventilation either through windows or the use of external air conditioning resources can provide the drop in temperature that is required to limited detrimental health effects. Churches though are not the only places that can provide this kind of shelter. Community centers provide another option of where people can either go to cool off because of the already established air conditioners in the building or on the contrary make contact and gather resources to make them hubs for cooling. The Central Harlem Senior Citizens Center provided multiple locations throughout Central Harlem (CHSCC, 2024) allowing for these spaces to be spread and reachable for those who lack the proper mobility to travel far distances especially when temperatures pose a threat. These two proposals dive deep into the concept of accessing the city and opening more spaces that can be claimed by and for Central Harlem community members.
Creation of Communal Programs
Elderly Checkups
By joining previously established groups, those who are able can proactively create parks and green spaces to cater more towards the population around them hence improving the ability to cool off, as well as transform spaces to be crucial keys to preventing heat related health consequences. Communities can also engage in mitigation techniques by creating their very own collectives. As mentioned previously, 77% of community members stated how they would be willing to help each other thus creating an environment where new groups can be welcomed. By creating a community checkup group during hotter months decreases the chances of not receiving the proper care to prevent or be guided through health episodes causes by extreme heat. Since older people are those who mainly lose the energy to move as much as they use to, they are subjected to being left alone or rely on others for services or tasks to be completed such as going to the grocery store or picking up the mail. The same applies to monitoring one’s health. In 2018, 11% of the population of Central Harlem was classified as being age 65 and above (NYC Health, 2018). New York City does have some services to take care of the older population. The Department of Aging provides a database of services focused on mental health, transportation, home care, case management and abuse prevention (NYC Department of Aging, 2024). Although the necessary tools are there to manage one’s health when heat becomes a problem, getting a clear and concise response can be the deciding factor of whether the matter is handled in an appropriate amount of time. NYC providers deal with millions of cases which does not guarantee that someone will receive the attention that is needed to deal with serious issues. Not to mention that the city has only so many employees to help cast a wide net of amenities to those in need. This is where communal check-ins are crucial. These collectives can be organized in different ways. Buildings can create these groups to do routine checkups on apartments that are inhabited by older persons. They can also be formed by bringing together those who live on the same block. This not only allows for a quick response time in the case of an emergency but also allows for neighbors who already have formed relationships to feel safe in difficult times. On the contrary, trust can also be formed through weekly and daily checkups. Volunteers can then adhere to those in need and act as an extension of them by moving them to a cooler area, retrieving medicine, or simply talking to calm them down in medical emergencies.
Tree Program for Children
While considering the elderly population is important, we must not forget the future. Children have every right to form groups based upon common interests. Harlem has a tree population of about 6,000 while other more economically prosperous areas like the Upper East Side has around 11,000 registered trees (NYC Parks, 2024). The areas may differ in size allowing for more trees to be planted. As a result, community members suffer from a lack of vegetation compared to other neighborhoods. As mentioned previously in the briefing, trees can act as natural coolers. Their shading of sidewalks and buildings can provide the needed drop in temperature to reduce the effects that the UHI can have on health. This proposal focuses mainly on children and their ability to learn and grow as humans. By introducing them to the management of trees on their streets and surrounding neighborhoods, feelings can be fostered about the importance of vegetation which may very well prevent friends and family from being affected by the UHI. One way in which the community of Central Harlem can go about doing this is by using the New York City Tree Map. This online tool provides the location of 873,677 trees in New York City and categorizes them by area, species, trunk diameter, and provides a unique tree ID (NYC Parks, 2024). By engaging with such a platform kids will be able to monitor and report about trees which they can explore both tangibly and in an abstract manner. This way knowledge about the importance of trees can be transferred in a way that can be easily understood. Children having gained such knowledge can then, through the facilitation of adults, can create their own groups with friends or neighbors. Not only will the groups yield a better grasp of natures gifts, but also create a bond between neighborhoods further increasing the community’s sense of togetherness.
Conclusion
I hope that these recommendations as well as stating hard facts about what is happening within Central Harlem can both bring attention to and inspire its population. I would like to echo that my recommendations come from independent, not on-site research. I presented my findings to help and support those in danger of bad health so that they may live life to the fullest, while cultivating a sense of environmental and urban justice. By bypassing political processes and NGO involvement, this briefing praises those willing to make change happen by using the power they possess.
