Vulnerability and poverty levels remain stubbornly high and arguably are deepening in many pastoral areas of the Horn of Africa. This is in spite of galloping livestock commercialisation in these areas and their closer incorporation into wider systems of marketing, trade and investment. The fact remains that the benefits of recent growth and investment in pastoral areas have yet to result in wider benefits for addressing food insecurity and poor nutrition. Chronically food insecure, poor or vulnerable people with limited assets cannot engage in or contribute to more productive livestockkeeping or other growth-oriented economic activities that are the intended focus of the New Alliance. Thus, strengthening social protection systems in the region is a prerequisite for realising more inclusive growth at the pastoral margins. This brief details the role of social protection in agendas to promote agricultural growth, highlighting areas of innovative programme design and implementation where further efforts might focus.
