Abstract
Insects such as the black soldier fly (BSF) are a nutritious feed component for livestock with high protein levels. BSF can be reared on a wide range of organic residual streams. This allows for local production within a circular agriculture, decoupling livestock production from import of expensive feed components, such as fishmeal or soymeal. Rearing of BSF can be done by smallholder farmers, thus contributing to their livelihood, economic sustainability and social status. Smallholder farmers contribute importantly to food security, which is a prerequisite for a stable society. In armed conflicts, smallholder farmers are usually the first to suffer. In countries recovering from conflict, agricultural development should focus on restoring food production by smallholder farmers, improving their socio-economic position, thereby contributing to sustainable development goals 2 (zero hunger) and 16 (peace and justice). Here, we focus on these SDGs with an example of reintegration of ex-combatants as smallholder insect producers in post-conflict Colombia.

In this paper we focus on insects for feed as a contribution to sustainable development goals (SDGs) 2 and SDG 16
We focus on opportunities to produce insects as feed to support the transition from conflict to peace in Colombia
Summary
Insects are food to a wide variety of organisms including livestock and humans [1]. Employing insects as food and feed is gaining ample interest because the production of these animals may provide high-quality proteins, with lowvalue input, high-value output and low environmental impact compared to traditional sources of animal protein [2]. Become an important component of a sustainable, circular agriculture by closing nutrient and energy cycles, fostering food security while minimising climate change and biodiversity loss. This meets various of the sustainable development goals of the United Nations [3] (Box 1; Figure 1). Flies as feed: black soldier fly as an example Fly larvae, such as the Black Soldier Fly (BSF) (Hermetia illucens L.; Diptera: Stratiomyidae) can be reared sustainably on a wide variety of organic waste streams and have an excellent nutritional quality [3,15]. The adult flies have a body length of 13À20 mm, their cuticle is black except the white halteres, tarsal leg parts and two opaque ‘windows’ in the anterior dorsal abdomen. Female flies produce 800–1200 eggs in large batches that they deposit in crevices close to decaying organic www.sciencedirect.com
