Street smarts

New Post has been published on https://thedigitalinsider.com/street-smarts/

Street smarts

Dozens of major research labs dot the streets of Kendall Square, a Cambridge, Massachusetts, neighborhood in which MIT partially sits. But for Andres Sevtsuk’s City Form Lab, the streets of Kendall Square themselves, and those in other cities, are subjects for research.

Sevtsuk is an associate professor of urban science and planning at MIT and a leading expert in urban form and spatial analysis. His work examines how the design of built environments affects social life within them. The way cities are structured influences whether street-level retail commerce can thrive, whether and how much people walk, and how much they encounter each other face to face.

“City environments that allow us to get more things done on foot tend to not only make people healthier, but they are more sustainable in terms of emissions and energy use, and they provide more social encounters between different members of society, which is fundamental to democracy,” Sevtsuk says.

However, many things Sevtsuk studies do not come with much pre-existing data. While some aspects of cities are studied extensively — vehicle traffic, for instance — fewer people have studied how urban planning affects walking and cycling, which most city governments seek to increase.

To counter this trend, several years ago Sevtsuk and some research assistants began studying foot traffic in several cities, as well as Kendall Square — how much people walk, where they go, and why. Most urban walking trips are destination-driven: People go to offices, eateries, and transit stops. But a lot of pedestrian activity is also recreational and social, such as sitting in a square, people-watching, and window-shopping. Eventually Sevtsuk emerged with an innovative model of pedestrian activity, which is based around these spatial networks of interaction and calibrated to observed people counts.

He and his colleagues then scaled up their model and took it to major cities around the world, starting with the whole downtown of Melbourne, Australia. The model now includes detailed street characteristics — sidewalk dimensions, the presence of ground floor businesses, landscaping, and more — and Sevtsuk has also helped apply it to Beirut and, most recently, New York City.

The project is typical of Sevtsuk’s research, which creates new ways to bring data to urban design. In 2023, Sevtsuk and his colleagues also released a novel open-source tool, called TILE2NET, to automatically map city sidewalks from aerial imagery. He has even studied interactions on the MIT campus, in a 2022 paper quantifying how spatial relatedness between departments and centers affects communications among them.

“Applying spatial analytics to city design is timely today because when it comes to cutting carbon emissions and energy consumption, or improving public health, or supporting local business on city streets, they relate to how cities are configured,” Sevtsuk says. “Urban designers have historically not been very focused on quantifying those effects. But studying these dynamics can help us understand how social interactions in cities work and how proposed interventions may impact a community.”

For his research and teaching, Sevtsuk received tenure at MIT earlier this year.

Growing and living in cities

Sevtsuk is originally from Tartu, Estonia, where his experiences helped attune him to the street life of cities.

“I do think where I come from enhanced my interest in urban design,” Sevtsuk says. “I grew up in public housing. That very much framed my appreciation for public amenities. Your home was where you slept, but everything else, where you played as a child or found cultural entertainment as a teenager, was in the public sphere of the city.”

Initially interested in studying architecture, Sevtsuk received a BArch degree from the Estonian Academy of Arts, then a BArch from the Ecole d’Architecture de la Ville et des Territoires, in Paris. Over time, he became increasingly interested in city design and planning, and enrolled as a master’s student at MIT, earning his SMArchS degree in 2006 while studying how technology could help us better understand urban social processes.

“MIT had a very strong research orientation for even masters-level students,” Sevtsuk says. “It is famous for that. I came because I was drawn to the opportunity to get hands-on into research around city design.”

Sevtsuk stayed at MIT for his doctoral studies, earning his PhD in 2010, with the late William Mitchell as his principal advisor. “Bill was interested in the influence of technology on cities,” says Sevtsuk, who appreciated the wide-ranging intellectual milieu that sprang up around Mitchell. “A lot of fascinating and intellectually experimental people gravitated around Bill.”

With his PhD in hand, Sevtstuk then joined an MIT collaboration at the new Singapore University of Technology and Design, a couple of years after it first opened.

“That was a lot of fun, building a new university, and we were teaching the first cohort and first courses,” Sevtsuk says. “It was an exciting project.”

Living in Asia also helped open doors for some hands-on research in Singapore and Indonesia, where Sevtsuk worked with city governments and the World Bank on urban planning and design projects in several cities.

“There was not a lot of data, and yet we had to think about how spatial analyses could be deployed to support planning decisions,” Sevtsuk says. “It forced you to think how to apply methods without abundant data in the traditional sense. In retrospect some of the software around pedestrian modeling we developed was influenced by these constraints, from understanding the minimum data inputs needed to capture people’s mobility dynamics in a neighborhood.”

From Melbourne to the Infinite Corridor

Returning to the U.S., Sevtsuk took a faculty position at Harvard University’s Graduate School of Design in 2015. He then joined the MIT faculty in 2019.

Throughout his career, Sevtsuk’s projects have consistently added insight to existing data or created all-new repositories of data for wider use. His team’s work in Melbourne leveraged a rare case of a city with copious pedestrian data of its own. There, Sevtsuk found the model not only explained foot traffic patterns but could also be used to forecast how changes in the built environment, such as new development projects, could affect foot traffic in different parts of the city.

In Beirut, the modeling work on improving community streets is part of post-disaster recovery after the Beirut port explosion of 2020. In New York, Sevtsuk and his colleagues are studying the largest pedestrian network in the U.S., covering all five boroughs of the city. The TILE2NET project, meanwhile, provides information for planners and experts in an area — sidewalk mapping — which most places do not have data on either.

When it came to studying the MIT campus, Sevtsuk brought new a new approach to a subject with an Institute legacy: An earlier campus professor, Thomas Allen of the MIT Sloan School of Management, did pioneering research about workspace design and collaboration. Sevtsuk and his team, however, looked at the larger campus as a network.

Linking spatial relations and email communication, they found that not only does the level of interaction between MIT departments and labs increase when those units are spatially closer to each other, but it also increases when their members are more likely to walk past each other’s offices on their daily routes to work or when they patronize the same eateries on campus.

Urban design for the people

Sevtsuk thinks about his own work as being not just data-driven but part of a larger refashioning of the field of urban design. In American cities, urban design may still be associated with the large-scale redevelopment of neighborhoods that took place in the first few postwar decades: massive freeways tearing through cities and dislocating older business districts, and large housing and office projects undertaken in the name of modernization and tax revenue increases but not in the interests of existing residents and workers. Many of these projects were disastrous for urban communities.

By the 1960s and 1970s, urban planning programs around the country attempted to quell the inadequacy of large-scale urban design and instead focused on the social and economic needs of communities first. The role of urban design was somewhat sidelined in this transition. But instead of giving up on urban design as a tool for community improvement, Sevtsuk thinks that planning and urban design research can help uncover the important ways in which design can support communities in their daily lives as much as community development initiatives and policies can.

“There was a turn in the field of planning away from urban design as a central area of focus, toward more sociologically grounded community-driven approaches,” Sevtsuk says. “And for good reasons. But during these decades, some of the most anti-urban, car-oriented, and resource-intensive built environments in the U.S. were created, which we now need to deal with.”

He adds: “In my work I try to quantify effects of urban design on people, from mobility outcomes, to generating social encounters, to supporting small local businesses on city streets. In my research group we try to connect urban design back to the qualities that people and communities care about. Faced with the profound climate challenges today, we must better understand the influence of urban design on society — on carbon emissions, on health, on social exchange, and even on democracy, because it’s such a critical dimension.”

A dedicated teacher, Sevtsuk works with students with broad backgrounds and interests from across the Institute. One of his main classes, 11.001 (Introduction to Urban Design and Development), draws students from many departments — including computer science, civil engineering, and management — who want to contribute to sustainable and equitable cities. He also teaches an applied class on modeling pedestrian activity, and his research group draws students and researchers from many countries.

“What resonates with students is that when we look closely at the complex organized systems of cities, we can make sense of how they work,” Sevtsuk says. “But we can also figure out how to change them, how to nudge them toward collective improvement. And many MIT students are eager to mobilize their amazing technical skills towards that quest.”

The future of food in a changing climate

Written by: Jagriti Shahi, Business Analyst at Global Launch Base

Introduction

Figure 1: Global Temperature over the Century

This data shows that global temperatures have been rising steadily over the past few decades. The rate of warming is expected to accelerate in the coming years, if we do not take action to reduce greenhouse gas emissions.

The Intergovernmental Panel on Climate Change (IPCC) has warned that if we do not take action to reduce greenhouse gas emissions, global temperatures could rise by as much as 5.2 degrees Celsius by the end of the century. This would have devastating consequences for the planet, including more extreme weather events, rising sea levels, and mass extinctions. The data is clear that we are facing a serious challenge, and we need to take action now to reduce greenhouse gas emissions and mitigate the effects of climate change.

Climate Change and Food Production

Figure 2: Climate Change Impact on Food Production

This data shows that the % change in yield of different crops by 2050 is already starting to be felt in 2022. For example, rice yields are already 1% lower in 2022 than they were in 2020. This is likely due to the combination of climate change and other factors, such as pests and diseases.

The trend is expected to continue in the coming years, as climate change continues to impact crop yields. This could have a serious impact on food security, as it will make it more difficult to produce enough food to feed the world's growing population.

The intricate relationship between climate change and food production is reshaping agricultural landscapes, challenging traditional practices, and compelling us to explore innovative solutions to ensure global food security. In this article, we delve into the intricate interplay between climate change and food production, highlighting the challenges faced and the potential pathways toward a more resilient future.

Altered Growing Conditions: One of the most immediate and palpable impacts of climate change on food production is the alteration of growing conditions. Rising global temperatures influence the length of growing seasons and shift the geographic suitability of certain crops. In some regions, this leads to reduced yields, as crops may experience stress due to excessive heat, prolonged droughts, or erratic precipitation patterns. Conversely, other areas might witness extended growing seasons, presenting opportunities to cultivate new varieties of crops.

Increased Pest and Disease Pressure: As the climate warms, pests and diseases that were once constrained by temperature limitations are expanding their ranges, posing significant threats to crops and livestock. The increased prevalence of pests can lead to reduced yields and necessitate more intensive use of pesticides, raising environmental concerns and potentially compromising food safety.

Water Scarcity and Agricultural Droughts: Climate change exacerbates water scarcity, a critical factor in agricultural productivity. Changing precipitation patterns and the intensification of droughts can jeopardize water availability for irrigation, which is essential for many crops. This can force farmers to compete for limited water resources, driving up costs and reducing overall agricultural output.

Impacts on Livestock Production: Livestock farming, a vital component of global food systems, is also vulnerable to the effects of climate change. Heat stress can lead to reduced livestock productivity, affecting meat and milk production. Moreover, changing forage availability due to altered precipitation patterns can challenge livestock feed supply, leading to increased costs for farmers.

Soil Degradation and Erosion: Climate change can exacerbate soil degradation and erosion, undermining agricultural sustainability. Intense rainfall events can lead to soil erosion, stripping away fertile topsoil and diminishing its ability to support crop growth. Soil degradation impacts soil structure, nutrient content, and water-holding capacity, posing a significant threat to long-term food security.

Adaptation and Mitigation Strategies: To address these challenges, a combination of adaptation and mitigation strategies is required.

Adaptation: Farmers can adopt climate-resilient practices such as crop diversification, agroforestry, and improved water management. Planting diverse crop varieties can spread risk and enhance resilience to changing conditions. Agroforestry systems, which combine trees with crops or livestock, can stabilize soil, conserve water, and provide additional income sources. Implementing efficient irrigation techniques and rainwater harvesting can help manage water scarcity.

Mitigation: Mitigating climate change through the reduction of greenhouse gas emissions is a critical step toward safeguarding food production. Sustainable land management, reforestation, and the adoption of renewable energy sources can contribute to lowering emissions from the agricultural sector.

7. Technological Innovations: Advancements in technology hold promise for enhancing climate resilience in food production. Precision agriculture utilizes data-driven approaches to optimize resource use, monitor crop health, and reduce waste. Climate-resilient crop varieties developed through traditional breeding or genetic modification can enhance yields under changing conditions.

8. Policy and International Cooperation: Global efforts are indispensable in addressing the complex challenges posed by climate change and food production. International agreements and policies can incentivize sustainable agricultural practices, support smallholder farmers, and promote technology transfer.

This data shows that there is a growing interest in innovative agricultural practices. This is likely due to the increasing awareness of the environmental impact of traditional agriculture and the need for more sustainable food production methods.

Innovative Agricultural Practices: Navigating the Future of Sustainable Food Production

In a world where climate change and environmental degradation pose unprecedented challenges to traditional agricultural practices, innovation emerges as a beacon of hope. Innovative agricultural practices are essential not only for meeting the growing global demand for food but also for ensuring the long-term sustainability of our planet. In this article, we explore a spectrum of groundbreaking techniques that are transforming the way we cultivate crops, rear livestock, and manage natural resources.

Agroecology: Harmonizing Nature and Agriculture: Agroecology is a holistic approach that seeks to mimic natural ecosystems within agricultural systems. By fostering biodiversity, enhancing soil health, and minimizing external inputs, agroecological practices promote resilient and sustainable food production. Techniques such as intercropping, cover cropping, and crop rotation reduce the reliance on synthetic fertilizers and pesticides, mitigating the environmental impact of conventional agriculture.

Precision Agriculture: Merging Technology and Farming: Precision agriculture leverages cutting-edge technologies, including GPS, remote sensing, and data analytics, to optimize resource utilization and enhance productivity. By precisely mapping variations in soil and crop conditions, farmers can tailor irrigation, fertilization, and pest control measures, minimizing waste and maximizing yields. Drones, sensors, and automated machinery further streamline operations and minimize environmental footprint.

Vertical Farming and Hydroponics: Farming in Tight Spaces: Vertical farming and hydroponics redefine the boundaries of traditional agriculture by enabling food production in urban environments and underutilized spaces. Vertical farms stack crops in vertical layers, utilizing artificial lighting and controlled environments to optimize growth. Hydroponics, a soilless cultivation method, delivers water and nutrients directly to plant roots, reducing water usage and enabling year-round production.

Conservation Tillage and No-Till Farming: Preserving Soil Health: Conventional tillage practices disrupt soil structure and contribute to erosion, compaction, and carbon loss. Conservation tillage and no-till farming minimize soil disturbance, maintaining soil structure and organic matter. This enhances water retention, reduces erosion, and sequesters carbon, making farms more resilient to extreme weather events and contributing to climate change mitigation.

Aquaponics: Symbiotic Aquaculture and Hydroponics: Aquaponics integrates aquaculture (fish farming) and hydroponics in a mutually beneficial system. The fish waste provides nutrients for hydroponically grown plants, which, in turn, filter and purify the water for the fish. This closed-loop system conserves water, eliminates the need for synthetic fertilizers, and yields both protein and vegetables.

Controlled Environment Agriculture: Climate-Proofing Crop Production: Controlled environment agriculture (CEA) encompasses greenhouse and indoor farming, allowing year-round cultivation of crops under precisely managed conditions. CEA protects plants from extreme weather, pests, and diseases while optimizing resource efficiency. High-tech greenhouses use advanced climate control systems, enabling growers to fine-tune temperature, humidity, and light levels for optimal plant growth.

Permaculture: Designing Sustainable Ecosystems: Permaculture draws inspiration from natural ecosystems to create self-sustaining and regenerative agricultural systems. By integrating diverse plant and animal species, permaculture designs promote ecological harmony, resilience, and long-term productivity. Food forests, which emulate natural forests with layers of edible plants, exemplify permaculture principles and provide a wide array of harvestable foods.

Urban Agriculture: Nourishing Cities Locally: Urban agriculture transforms urban landscapes into productive spaces, mitigating the environmental impact of food transportation and enhancing food security. Rooftop gardens, community plots, and vertical farms bring fresh produce to city dwellers while fostering a sense of community and reconnecting people with their food sources.

Key players in the market:

Resilient Crop Varieties

The development of climate-resilient crop varieties through breeding and genetic modification is crucial. Scientists are working on crops that can withstand higher temperatures, require less water, and exhibit resistance to pests and diseases. Gene editing techniques like CRISPR-Cas9 offer precise methods to enhance desired traits, potentially revolutionizing crop production. However, careful consideration of ethical and environmental implications is essential in adopting such technologies.

As the world grapples with the uncertainties of a changing climate, ensuring a steady and nutritious food supply has become a paramount challenge. Resilient crop varieties, born from innovative breeding techniques and scientific advancements, offer a glimmer of hope in the face of shifting weather patterns, changing pest dynamics, and dwindling natural resources. In this article, we delve into the significance of resilient crop varieties and the transformative potential they hold for securing global food security.

1. The Need for Resilience

Traditional crop varieties, often developed for specific regions and historical climatic conditions, are increasingly vulnerable to the unpredictable and extreme weather events wrought by climate change. Droughts, floods, heatwaves, and new pest and disease pressures threaten agricultural productivity and food availability. Resilient crop varieties possess traits that enable them to withstand and recover from these challenges, ensuring a consistent supply of food even in the face of adversity.

2. Breeding for Resilience

The art and science of breeding resilient crop varieties involve a combination of classical breeding methods and cutting-edge technologies. Plant breeders select and cross plants with desirable traits, such as drought tolerance, disease resistance, and improved nutrient uptake. Advancements in molecular biology, genetic mapping, and gene editing techniques like CRISPR-Cas9 enable scientists to precisely manipulate plant genomes, accelerating the development of resilient varieties.

3. Drought-Resistant Varieties

Drought is a major concern for agricultural regions worldwide. Resilient crop varieties with enhanced water-use efficiency and deep root systems can thrive with limited water availability. Genetic modifications that control stomatal opening and closing, reducing water loss through transpiration, are being explored to confer drought tolerance.

4. Disease and Pest Resistance

Pests and diseases can devastate crop yields, leading to food shortages and economic losses. Resilient crop varieties can be engineered with natural pest repellents, reducing the need for chemical pesticides. Genetic markers linked to disease-resistance genes are identified to expedite breeding efforts, resulting in more robust crops.

5. Heat and Cold Tolerance

Extreme temperatures, whether scorching heat or chilling cold, disrupt plant metabolism and growth. Resilient crop varieties can be developed with genetic traits that enable them to thrive in temperature extremes. Heat-tolerant crops might possess heat-shock proteins that protect cellular structures, while cold-tolerant crops could have antifreeze proteins that prevent ice-crystal formation.

6. Salinity and Soil Adaptation

As sea levels rise and agricultural lands become salinized, crops need to tolerate higher levels of salt in the soil. Resilient crop varieties can be bred to thrive in saline conditions, ensuring continued food production on affected lands. Breeding for improved nutrient uptake and utilization also contributes to healthier plants and improved yields.

7. Biodiversity and Resilience

Maintaining a diverse array of crop varieties is essential for building resilience. Traditional and heirloom varieties often possess unique traits that can be crucial for adaptation. Initiatives to conserve and promote local crop diversity are essential for safeguarding food security in a changing world.

Water: A Precious Commodity: In a changing climate, water scarcity and variability become magnified challenges for agricultural production. Sustainable resource management involves optimizing water use through techniques like drip irrigation, rainwater harvesting, and integrated water management systems. By safeguarding water sources, improving distribution, and minimizing wastage, we ensure a consistent supply of this invaluable resource to sustain food production.

Soil Health and Carbon Sequestration: Healthy soils play a pivotal role in both climate mitigation and adaptation. Sustainable resource management practices prioritize soil health through reduced tillage, cover cropping, and organic matter enrichment. These strategies not only enhance soil fertility and water retention but also contribute to carbon sequestration, mitigating the atmospheric buildup of greenhouse gasses.

Biodiversity Conservation for Resilient Ecosystems: Preserving biodiversity within agricultural landscapes is central to sustainable resource management. Diverse ecosystems are more resilient to climatic fluctuations and provide natural pest control, pollination services, and soil fertility. Agroecological approaches, such as crop rotation, agroforestry, and maintaining habitat corridors, support diverse species and foster ecosystem health.

Circular Economy and Waste Reduction: A circular economy approach within food systems minimizes waste and resource depletion. Sustainable resource management encourages reducing food waste, adopting efficient packaging, and promoting composting or recycling of organic matter. By embracing a circular mindset, we reduce the burden on landfills, conserve resources, and limit the environmental footprint of food production and consumption.

Sustainable Trade and Supply Chain Policies International trade and supply chains are integral to global food security. Policies that promote sustainable trade practices, reduce trade barriers and ensure equitable access to markets contribute to stable food supplies and price stability, benefiting both producers and consumers. 6. Strengthening Smallholder Resilience Policies that specifically target smallholder farmers, who are often the most vulnerable to climate impacts, play a vital role in enhancing food security. Financial support, access to credit, and extension services empower smallholders to adopt climate-resilient practices and diversify their livelihoods. 7. Public-Private Partnerships Collaboration between governments, private sector entities, and civil society organizations amplifies the impact of climate-resilient policies. Public-private partnerships drive innovation, leverage resources, and facilitate knowledge exchange, ensuring that policies are implemented effectively and that a wide array of stakeholders are engaged. 8. Education and Consumer Awareness Policies that promote consumer education and awareness campaigns raise consciousness about sustainable consumption practices. Clear labeling, educational initiatives, and public awareness campaigns inform consumers about the environmental and social impacts of their food choices, influencing demand and driving market shifts.

Conclusion

The future of food in a changing climate is a complex challenge that demands immediate attention and collaborative efforts. Innovations in agriculture, sustainable resource management, and climate-resilient practices offer hope for ensuring food security for a growing global population. By embracing new technologies, promoting sustainable practices, and fostering international cooperation, we can navigate the challenges presented by a changing climate and build a more resilient and secure food future for generations to come. ------------------------------------ Global Launch Base helps international startups expand in India.
