    Prosopis juliflora is a thorny, dominant and thirsty tree species that has invaded the main grazing areas in many countries in the Horn of Africa (HoA), posing a major threat to rural livelihoods. The scale of Prosopis expansion is dramatic in the region, e.g. more than one million hectares in both Kenya and Ethiopia, respectively. Widespread planting of Prosopis in Somalia took place in the 1980s as a response to deforestation during and after the Ethio-Somali war and subsequent droughts. Since then it has spread vigorously, invading at least 550,000 hectares in Somaliland alone. However, the Prosopis expansion in Somalia is at a relatively early stage compared to other countries in HoA and there is an opportunity to introduce management before it is too late. Between 2016-18, the Food and Agriculture Organization (FAO) in Somalia collaborated with the NGO Pastoral and Environmental Network in the Horn of Africa (PENHA) and developed a project entitled “Supporting communities in Somaliland to ‘make Prosopis make money’ through Cash-For-Work (CFW) and small business development”, in Berbera, Odweyne and Toghdeer districts of Somaliland. This project was a component of the Joint Programme on Youth Employment (YES) between the Federal Government of Somalia (FGS) and United Nations (UN). It aimed to create entrepreneurial and employment opportunities for women and youth to efficiently manage Prosopis pods by processing them into animal livestock feed supplements and charcoal. Moreover, the project established and fostered livestock feed processing cooperatives by creating market linkages.

    Due to the increasing pressure of a globalized economy and under the effects of a changing climate, biological invasions have become a frequent feature of marine and freshwater environments. Global fisheries and aquaculture are therefore required to adjust to these changes, with the dual aim of reducing the negative ecological consequences caused by these species and making the most of the advantages they might bring.Here, capitalizing on a wide spectrum of management actions which can be implemented to control and/or adapt to aquatic invasions, nine measures are presented; they can be grouped under environmental, social or socioeconomic strategies, exploring their potential, main challenges and enabling factors. The nine measures, provided with key recommendations, are:#1: Develop and manage a commercial fishery#2: Promote recreational harvesting#3: Explore market opportunities#4: Implement outreach programmes#5: Foster stakeholder engagement#6: Implement spatial control#7: Implement biological control#8: Restore ecosystems#9: Do nothingThese suggestions, discussed among a group of international experts and presented in a synthetic form, may be used as a practical resource (though not an exhaustive one), to aid in the evaluation and identification of appropriate fisheries management responses to aquatic invasive species in the context of climate change. While it may not address all the complexities of the subject, it provides a starting point for adaptation strategies, recognizing the diverse legal, cultural and socioeconomic conditions in different fishery contexts, offering valuable insights for policymakers, fisheries managers, and practitioners who have to deal with aquatic invasions.
