Nature-based Solutions (NbS) work with nature to benefit both natural ecosystems and the people that depend on them. By putting nature at the centre, NbS address a range of societal challenges: protecting, sustainably managing or restoring natural or modified ecosystems and supporting their health, function and biodiversity.

The research collated in this brief confirms that NbS deliver simultaneously multiple benefits and shows the wide-ranging beneficial impacts of scaling up their implementation across Europe.

Since the mid-1980s, the positive impacts of these simple, cost-efficient water harvesting techniques become clear, following their increasingly widespread adoption. Their use has allowed smallholders to reverse land degradation, improve soil fertility, sustainably increase crop production, achieve food security, and create more productive, diverse and resilient farming systems. At the same time, groundwater is recharged, improving access to drinking water for the entire year, and creating opportunities for irrigated vegetable gardening around wells.

The latest IPCC report highlights that a change in diets for richer nations, and smarter land use, could ensure food security and mitigation of potential climate impacts.

Land surface processes — agriculture, forestry and other land use — account for 28% of anthropogenic emissions. However, natural land processes absorb about a third of the emissions from fossil fuel burning and energy production.

As a farmer in northern Kenya, I came to understand the importance of dryland restoration. After moving to Kaijaido country in the south, I started an initiative to restore the land, increase food security and reduce poverty, supported by a grant from the East African Community with various activities supported by FAO and Yale University.

In the above initiatives, self-motivated populations increased food security and reduced vulnerabilities to climatic shocks by restoring and sustainably managing local forest resources. To regenerate agroforestry parklands, farmers built on traditional systems to increase on-farm tree density and convert degraded lands to densely wooded savannas. These actions increased crop yields and produced new sources of livestock browse. The population of Sambandé restored the local forest and managed it to sustainably produce fuel and fruit.

The adoption of FMNR increased by 50% over 20 years; about 90% of all farmers now encourage natural regeneration on the land that they manage. The key to success is having local institutions that are respected and effective. The experience in Bankass shows that reforestation rates of at least 250 trees per hectare can be achieved by farmer managed natural regeneration on Sahelian agricultural lands, recreating an agroforestry parkland at a fraction of the cost of establishing conventional plantations.

Unless countries can manage to mobilize millions of land users to invest their scarce resources in protecting regenerating trees, the battle against land degradation cannot be won. These experiences from Niger show that hundreds of thousands of smallholder farm families have substantially increased tree cover on their farm land by investing in the management of on-farm trees. This has improved their production systems and their livelihoods. There is no reason to believe that similar success cannot be achieved in many more countries throughout African drylands and sub-humid area.

Ecosystems and Biodiversity Facts and Figures # The IPBES Report (5) stated that “around 1 million animal and plant species are now threatened with extinction, many within decades, more than ever before in human history”.

The climate-smart village approach created enthusiasm and commitment from farmers in seeking solutions to the problems and constraints that they themselves identified. The approach also involved strengthening the capacity of technical staff to use new tools, and to understand and support the new methods, with complementary finance to support the changes.

The food system challenges require simultaneous action across different sectors and concerted efforts of diverse players in food systems. While past efforts inclined towards boosting gricultural production, today’s focus has shifted to influencing transformative changes to the entire food systems continuum, from production and processing to marketing and distribution, using innovative solutions. Sub-Saharan Africa has been facing unprecedented challenges that affect the sustainability of food and agriculture systems, putting food and nutrition security at significant risk.

When the IFAD-funded project started in 1988, few people could have imagined that 15 years later the degraded plateaus would be covered with trees on land restored to production by individual smallholder farmers. And no one imagined that a village on a barren degraded plateau would one day produce enough vegetables to meet its own needs and produce a surplus for sale, because water levels in the wells had risen so much.

The paper focuses on the need to rethink conventional wisdom on land tenure approaches and asks how we can best respond to the land tenure problems. It provides a comparative overview of land tenure systems in the drylands, identifies challenges and trends in land tenure reform projects, and offers ideas for decision-makers
