This study was undertaken to examine local perceptions of the impacts of small-scale tree plantations, notably of Acacia decurrens (J.C. Wendl.) Willd., in Ethiopia’s Upper Blue Nile Basin. A particular focus of our study was on the different dimensions of livelihood sustainability centering on economic, social, human, physical, and natural capital.

Food security in Africa needs abundant, affordable and nutritious food for the growing population.
•Smallholder farmers lack sufficient land or economic incentives to invest in agriculture.
•The above issues create a ‘wicked problem’ – a conundrum for future food security.

The paper critically engages with sustainable development goal targets (SDG-2- Target 2.3; SDG-5) to examine how and why large-scale agricultural land acquisitions modify the social relations of women’s food access. The study draws from impacts of various plantation schemes in Cameroon and Ghana.

In sub-Saharan Africa, the urban majorities are financially excluded from the formal housing markets and reside in informal settlements. Limited knowledge on the development of informal settlements compromises the efficacy of urban planning and policies targeting such areas.

Urban parks provide various environmental, socio-cultural and economic benefits, also called ecosystem services, as well as challenges. Urban park planning and management needs to consider the perception and attitude of people towards the benefits, challenges and quality of the parks. However, such information is largely lacking for cities of Sub-Saharan Africa.

The “Responsible Governance of Investments in Land” (RGIL) project in Ethiopia aims at ensuring that investments in land are productive, contribute to sustainable land management, and respect the rights and needs of local populations, in particular vulnerable groups and women.

Although land forms the basis for marginal livelihoods in Sub-Saharan Africa, the asset is more strategic for women as they usually hold derived and dependent rights to land in customary tenure areas.

Ghana is urbanising rapidly, and over half of the country’s population have lived in urban areas since 2010.

Land tenure security, especially customary residence systems, is found to influence the agricultural investment decision-making and productivity of smallholder farmers across sub-Saharan Africa. However, as country-specific customary residence systems and farming models evolve over time, their impact on food security and livelihood remains unclear.

After more than ten years of hectic debates on international ‘land grabs’, academic interest in collapsed land deals or projects with unexpected results is growing. According to the Land Matrix, Tanzania is one of the target countries for such deals, with a number ‘abandoned’ or delayed and projects whose status is unknown.
