  • E239: National report on where the grocery stores are missing

    E239: National report on where the grocery stores are missing
    Jul 16 2024
    Today we're talking about who has access to full-service supermarkets in America's cities, suburbs, small towns and rural communities. According to The Reinvestment Fund's "2023 Limited Supermarket Access Analysis Report," 8.5% of people in the US live in areas with limited access to full-service supermarkets. This means that families must travel further to get fresh foods, and it creates a barrier to adequate nutrition. This is the 10th year The Reinvestment Fund has published the "Supermarket Access Report," which provides data and context about grocery store access across the country. Here to discuss the latest figures is policy and analyst Michael Norton. Interview Summary This is a really interesting and kind of nuanced topic, so I'm happy we can talk about it in some detail. Why don't we just start off with kind of a broad question. What do we know now about areas of limited supermarket access in the US? Kelly, I think the big thing to take away at the very beginning is that the share of people living in places that would be considered low access is roughly the same as it's been over the past 10 years. We have about 8.5% of the population living in low-access areas across the country. That's pretty consistent to what it's been for over a decade. But what's important is that how low-access areas are distributed across the country varies quite a bit. And where they exist, the density of the populations where they exist, really informs the kinds of interventions that are available for addressing these needs. These vary considerably in different parts of the country and at different geographic scales. And what I mean by that is suburban areas, rural areas, and then some of the most remote areas across the country. So we do have a sort of consistent number or share of people. The actual number has gone up a little bit because the population has continued to increase. They become distributed in different ways that follow different kinds of development patterns, on the one hand. But then also places where you end up getting patterns of residential and racial segregation in more developed parts of the country. It's so interesting. So, given that the average has stayed essentially the same over the 10 years you've been doing the reports, have there been pressures pulling in either direction that might have changed over the years? So, for example, are there pressures that are making access to full-service supermarkets less likely? Are they pulling out of some places, for example? And might that offset by some positive developments in other areas? So, while the average stays the same, the contours look different? I think the way to think about that is that we see a lot of expansion of low-access areas in the big metro areas that are expanding the fastest. So, the biggest increases in populations living with limited access are in big state in the South and out west in places like Arizona, Nevada, Texas, where you have these large metros that are growing at a really rapid rate. And the reason for that is that oftentimes residential development will show up before commercial development. So, in those kinds of places, food retail is trailing behind residential development. And probably those places are going to be well served by the time we update this analysis again in four or five years because of what those development patterns look like, right? So, when you're building more houses in more urban and remote areas, there's still folks who are first in buying out in those places. They're still going to have to go a long way to get their groceries for a few years until supermarket identifies this as a place where there's going to be enough demand for us to put one of our Krogers or Targets or Walmarts or what have you. But we've also seen, and this is more common in urban places, is the expansion of these low-access areas that have smaller populations, right? And so these are places with between 1,000 and 5,000 residents where folks are still having to go disproportionately far to get access to a full-service grocery store. Sometimes this is because stores have pulled out in these places because of limited demand, historically. And that limited demand is mostly because folks don't have as much income to spend on their groceries, right? And we see these little areas popping up within metro areas and even in some close-in suburbs and places across the country. And so you have sort of these bigger LSA areas, which have at least 5,000 residents on the outer edges of a lot of metros and in some within the cities, but mostly within the cities. It's these smaller, limited access, low population areas. And this differentiation of the type of low-access area is something that we introduced in this update to our analysis that previously wasn't available. It provided a really nice nuance to understanding what limited access to supermarkets looks like going forward, both within urban places, suburban places, and in...

    E238: Celebrating the Successes of the Alliance for a Health Generation
    Jun 27 2024
    Nonprofit organizations can play a very important role in building healthy communities by providing services that contribute to community stability, social mobility, public policy, and decision-making. Today we're speaking with Kathy Higgins, CEO of the Alliance for Healthier Generation. The Alliance is a nonprofit organization, a well-known one at that, that promotes healthy environments so that young people can achieve lifelong good health. Interview Summary Kathy, it's really wonderful to reconnect that you and I interacted some when you were in North Carolina and head of the Blue Cross and Blue Shield of North Carolina Foundation, and then you got called upon to be the CEO of the Alliance, a really interesting position. It's really wonderful to be able to talk to you again. Let's start maybe with a little bit of the history of the Alliance for a Healthier Generation. Can you tell us a bit about how it got started and over the years, how it's evolved? We've existed for almost 19 years now. We celebrate our 20-year anniversary next year. And we were started by two vital public health forces: the Clinton Foundation and President Clinton and also the American Heart Association. They came together 20 years ago and began discussing childhood obesity and what could a leading public health organization do to really work in systems change across the country at a local level. It is those two organizations that we look to as our founders and who helped us advance our work. It's a time flies story because it seems like just yesterday that the Alliance was created. There was a lot of excitement at the time for it, and over the work. It's done some really interesting things. So, in today's iteration of the Alliance, what are some of the main areas of focus? As I mentioned, we are a systems change organization. What we do is take a continuous improvement approach to advancing children's health. So, we are working typically in schools or after school time and certainly in communities to work on policy and practice change that are about promoting physical activity and healthy eating. And then addressing critical child health and adolescent health issues, which as we know, were exacerbated with the pandemic. Things like food access and social connectedness are just so important. Quality sleep, which our children are not getting enough of, or other things like vaping and tobacco sensation and on time vaccinations. Another thing that we know is that the pandemic had a dramatic impact on families and children on time vaccinations. So, this is the work that we do and working with the policy and practice change so that there there can be opportunity for healthy environments for the children. I think most everybody would probably agree that the targets that you're working on, healthy diet, physical activity, smoking, vaping habits and things like that are really important. But people might be a little less familiar with what you mean by addressing systems. Could you give some examples of what you mean by that? Right. What we know is that in United States, in fact, every public school must have a wellness policy and areas that need to be addressed. But what we'll do is work with the school in making sure that those policies are best suited for the families, the community, and the school, and what they want to do to support the health of children from a collaborative and supportive role. What we know is that we can create great change when that occurs. We work with more than 56,000 schools across the United States, and one of the things that we know is that our approach is really reflected in the America's Healthiest Schools recognition program each year. It's interesting to hear you talk about schools as an example of system change. And boy, working with 56,000 schools is pretty darn impressive. And it allows for out-sized influence of an organization like yours because if you can affect things like these school wellness policies and that gets multiplied across a ton of schools, it can really affect a lot of children. Exactly. We will work school to school, but we also work in districts and that allows us then to make even a bigger impact in the number of schools that we're reaching with these changes. It also brings the community together because then they're all operating under the same principles or the same focus areas of the work that they're committed to doing. What we do see is that we're able to assist them in implementing what are typically best practices in all sorts of topic areas. Whether it's strengthening the social emotional health and learning environment for the children, but also focusing on staff wellness. The whole notion, Kelly, of putting your oxygen mask on first before assisting others is something that has been incredibly important to us. We've certainly been very supported to do that work from a variety of funders. The other area that we've been able to make great strides in is this ...

    E237: Agriculture impacts climate change more than you think
    May 24 2024
    Is it possible to decarbonize agriculture and make the food system more resilient to climate change? Today, I'm speaking with agricultural policy expert Peter Lehner about his climate neutral agriculture ideas and the science, law and policy needed to achieve these ambitious goals. Lehner is an environmental lawyer at Earthjustice and directs the organization's Sustainable Food and Farming Program. Transcript How does agriculture impact the climate? And I guess as important as that question is why don't more people know about this? It's unfortunate that more people don't know about it because Congress and other policy makers only really respond to public pressure. And there isn't enough public pressure now to address agriculture's contribution to climate change. Where does it come from? Most people think about climate change as a result of burning fossil fuels, coal and oil, and the release of carbon dioxide. And there's some of that in agriculture. Think about tractors and ventilation fans and electricity used for pumps for irrigation. But most of agriculture's contribution to climate change comes from other processes that are not in the fossil fuel or the power sector. Where are those? The first is nitrous oxide. Nitrous oxide is a greenhouse gas about 300 times more potent than carbon dioxide. And it comes because most farmers around the world and in the U.S. put about twice as much nitrogen fertilizer on their crops, on the land, as the plants can absorb. That extra nitrogen goes somewhere. Some of it goes off into the water. I'm sure your listeners have heard about harmful algae outbreaks or eutrophication of areas like the Chesapeake Bay and other bays where you just get too many nutrients and too much algae and very sick ecosystem. A lot of that nitrogen, though, also goes into the atmosphere as nitrous oxide. About 80% of nitrous oxide emissions in the U.S. come from agriculture. Excess fertilization of our hundreds of millions of acres of crop land. Quick question. Why would, because the farmers have to pay money for this, why do they apply twice as much as the plants can absorb? Great question. It's because of several different factors. Partly it is essentially technical or mechanical. A farmer may want to have the fertilizer on the land right at the spring when the crops are growing but the land may be a little muddy then. So they may have put it on in the fall, which is unfortunate because in the United States, in our temperate area, no plants are taking up fertilizers in the fall. Also, a plant is like you or me. They want to eat continually but a farmer may not want to apply fertilizer continuous. Every time you apply it, it takes tractor time and effort and it is more difficult. So they'll put a ton of fertilizer on at one point and then hope it lasts for a while, knowing that some of it will run off, but hopeful that some will remain to satisfy the plant. There's a lot of effort now to try to improve fertilizer application. To make sure it's applied in ways just the right amount at the right time. And perhaps with these what's called extended release fertilizers where you put it on and it will continue to release the nutrients to the plant over the next couple of weeks and not run off. But we have a long way to go. Okay, thanks. I appreciate that discussion and I'm sorry I diverted you from the track you were on talking about the overall impact of agriculture on the climate. I think what's so exciting about this area is that everyone cares about our food. We eat it three times a day or more and yet we know very little about where it comes from and its impacts on the world around us. It's wonderful to be talking about this. The second major source of climate change impact in agriculture is methane. Methane is another greenhouse gas much more powerful than carbon dioxide. About 30 times more powerful over a hundred years and about 85 times more powerful than carbon dioxide over 20 years. Which is I think the policy relevant time period that we're looking at because we're all trying to achieve climate stability by 2050. And where does methane come from? A little bit comes from rice, but the vast majority of it comes from cows and from manure. Cows are different than you and me. They can eat grass, and their stomachs are different, and release methane. Every time they breathe out, they are essentially breathing out this potent greenhouse gas methane. This is called enteric methane and it's the largest single source of methane in the United States. Bigger than the gas industry or the oil industry. The other major source of methane is manure. Our animals are raised in what are called concentrated animal feeding operations. They're not grazing bucolically on the pasture, they are crammed into buildings where there may be thousands, or tens of thousands, or even hundreds of thousands of these animals. Those hundreds of thousands of animals produce a vast amount of manure, whether it be say pigs...
