Piecework (ganyu) is short-term, casual labor common in rural Zambia and neighboring countries. Reliance on piecework as a strategy to cope during food shortages in the rainy/cultivation season can restrict own-farm production, and thus, is regarded as an indicator of a household's vulnerability to food insecurity. Based on a household's level of participation in piecework, we explore this claim in rural Zambia using survey data collected during the rainy and dry seasons in 2009. We argue that seasonal assessments are essential if such dependence on piecework is used as a robust measure of a household's vulnerability to food insecurity.
In Bangladesh, changes in the overall agricultural system have seen a continued decline in the areas of inland water and inundation, reducing the habitats for fish. This has contributed to decreased fish harvest, in particular for small fishes like the mola that the rural poor depend on. mola is a nutrient-rich small fish that supplies essential nutrients – in particular vitamin A, calcium, iron and zinc – to these vulnerable population groups.
Agricultural biodiversity is important for food and nutritional security, as a safeguard against hunger, a source of nutrients for improved dietary diversity and quality, and strengthening local food systems and environmental sustainability.
