Spring is here which means pest activity is on the rise. Termites are one of the top pest concerns for many city dwellers and rural residents alike. The infographic shows some interesting facts about termites. Here in California, there are three kinds...

Why do you love fruits and vegetables? Is it their bright colors? Their many shapes and varieties, the way they can makeover your plate with the seasons? The opportunity to taste local terroir in a very fresh bite of fruit or forkful of salad?
Is it more about the juiciness, crunchiness or succulence?
Or do you think more about nutrition? About vitamins, micronutrients and fiber, after decades of being encouraged to eat “5 A Day” to be healthy? Is it about that feeling of righteous virtue when you fill half your plate with fruits and vegetables — and know you're earning a gold star for eating right?
The importance of eating fruits and vegetables has been making headlines again recently, with studies refocusing on the concept of “nutrition security” in a changing climate and pushing for an emphasis on nutrient consumption. The EAT-Lancet commission — while mostly garnering headlines in the United States related to reduced meat consumption — also recommended a diet that would require almost every global region to increase its consumption of fruits and vegetables to meet healthy diet goals.
But there's another reason to love fruits and vegetables that might not be as obvious. Here's a 30-second video clip of what a young farmer in Uganda had to tell me about vegetables, when I had the chance to meet him last year:
“There's no quicker source of getting money in town,” Boaz Otieno explained, when discussing why he chose to farm instead of going to town to find a job. He also talked about the concept that he could grow vegetables like tomatoes on a smaller plot of land and earn as much for those tomatoes as a larger plot of corn or cassava.
"You might even grow (tomatoes) twice while the cassava is not yet harvested, so there's a lot of money in horticulture," he said.
Otieno is a farmer who was also working as a site coordinator for a research project led by Kate Scow in Uganda, which was supported by the Horticulture Innovation Lab, the USAID-funded research program that I work for at UC Davis. Elizabeth Mitcham, director of the Horticulture Innovation Lab and a UC Cooperative Extension specialist, often talks about the “double-duty impacts” of fruits and vegetables, as these crops can be a tool to achieve two major global goals: improving nutrition and reducing poverty.
And it's not just one farmer's opinion that horticultural crops can yield higher incomes. In a white paper about aligning the food system to meet fruit and vegetable dietary needs, the authors pointed out that data from Africa and Asia have shown farmer profits per hectare 3-14 times higher when growing vegetables versus growing rice. The paper also points out that USDA estimates fruits and vegetables account for 23 percent of production value in American agriculture, grown on less than 3 percent of the country's agricultural land. And here in California, fruits and vegetables are a $20 billion industry.
Later this month, the Horticulture Innovation Lab will be hosting a conference in Washington, D.C., focused on making the case for fruits and vegetables with the theme, “Colorful Harvest: From Feeding to Nourishing a Growing World.” The conference will bring together decision makers, international development practitioners, and researchers from universities across the United States, Africa, Asia and Central America to discuss how horticultural innovations can advance global issues of food security, food waste, gender empowerment, youth employment, malnutrition, and poverty reduction.
While the conference speakers and participants will be diverse, we're also working to bring farmers' voices — like Otieno's — into the conference with video clips from our partners in Nepal, Honduras, Rwanda and elsewhere, to explain what exactly it is that makes them love fruits and vegetables.

Eating healthy on a limited budget is possible, but any cuts in SNAP or rise in food costs make it harder
The affordability of healthy food is often cited as a barrier to low-income families eating nutritious meals. A new study published in the Journal of Nutrition Education and Behavior found that with menu planning and access to stores selling items in bulk, the average daily cost for serving healthy meals to a family of four was $25 in 2010 dollars. This cost was consistent with the US Department of Agriculture (USDA) low-income cost of food meal plan, but higher than the cost of the USDA Thrifty Food Plan. The Thrifty Food Plan is the meal plan used by the USDA to determine food assistance benefits.
“This study determined the likelihood that families living in low-income households could create meals that meet the USDA dietary guidelines presented in MyPlate nutrition education materials,” said lead author Karen M. Jetter, Ph.D., of the UC Agricultural Issues Center, which is part of UC Agriculture and Natural Resources. “In addition to food cost, the other factors considered were access to stores, time for meal preparation, and whether the menus included culturally appropriate foods.”
Jetter also cautioned that any reduction in SNAP, the federal Supplemental Nutrition Assistance Program for people with qualifying low incomes, or increase in food costs would make it hard for economically vulnerable families to eat healthy foods.
This project was conducted in collaboration with Northern Valley Indian Health, Inc, and the Mechoopda Indian Tribe of Chico Rancheria where 88 percent of the population surveyed lived in households with an income of less than or equal to $35,000 a year. The menus were created to feed a household with a father, mother, and children ages 7 and 10 with foods the Mechoopda Indian Tribe community liked to eat, met USDA guidelines for healthy eating, and had realistic portions. Menus did not rely on processed foods to reduce the amount of fat and salt in the family diet, were varied so the family would not become bored eating the same foods, did not always require hot meal preparation, and were affordable.
By working closely with the Mechoopda Indian Tribe community researchers, two-weeks of daily menus were developed using meal plans provided by the Mechoopda Indian Tribe community. Although these plans did not meet the nutritional guidelines every day, all categories achieved the recommended levels on average at the end of a two-week period.
“These menus showed that a healthy diet on a budget was achieved by balancing daily targets over two weeks, not every day. This focuses healthy eating on balance rather than being deprived,” said Jetter.
Once the menus were determined, the Mechoopda Indian Tribe community researchers visited 13 grocery stores in Chico to ascertain menu costs. The stores visited were within a 10-minute car ride of 76 percent of the Mechoopda Indian Tribe members and were classified as bulk supermarket, general supermarket, discount market, or specialty market such as a local co-op.
Both bulk and general supermarkets had the highest availability of the items needed for a two-week shopping list, whereas specialty and discount markets lacked as many as 52 of the items needed. Bulk and discount market baskets had the lowest average daily cost of $25, while the specialty market had the highest average cost of $39 per day.
One limitation of the study was the focus on the actual cost of food without considering transactional costs such as the time needed to plan menus, develop shopping lists, research store advertisements, and travel to the bulk supermarket that offered the lowest cost. All of these factors influence a family's ability to sustain a healthy eating plan.
“This research demonstrates that menus that meet USDA guidelines can be purchased by a family of four when shopping at a bulk supermarket, but any reduction in SNAP benefits or increase in food costs would make it difficult for these economically vulnerable families to maintain a healthy lifestyle,” stressed Jetter.
This project was part of a larger project funded by a National Institutes of Health grant.
