Discard produce when fruits have set (tomatoes, peppers, eggplant) or where you see edible buds (broccoli or cauliflower) at the time of flooding. Notice where rainwater flows during heavy downpours and avoid planting in areas where water collects, if possible. The unique features and drivers of urban food insecurity and unhealthy diets and the vast inequalities within urban areas require tailored programs and policies that specifically tackle the needs of the urban poor. The study, published recently in the Journal of Agriculture, Food and Environment, suggests that floating gardens might not only help reduce food insecurity, but could also provide income for rural households in flood-prone parts of Bangladesh. See Media Page for more interview, contact, and citation details. In many cases, it is challenging to determine what contaminants are in crops that were submerged by floodwaters.

These new measures are much more in line with the 1996 World Food Summit comprehensive and widely endorsed definition of food security, which states that food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious foods that meets their dietary needs and food preferences for an active and healthy life. Clearly, food security measures based only on quantity of food grossly underestimate the magnitude and severity of the problem and reflect only one of the many aspects of what food security really entails. In India, we find that the nutritional status of poor slum dwellers is similar to those of rural populations, challenging the myth that urban dwellers are generally better off than their rural counterparts. Urban dwellers are almost entirely dependent on the cash economy and therefore need stable employment and income for their food needs, whereas many rural households have access to land and grow a significant proportion of the food they consume.
