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 Great Green Wall is one of the main vehicles for delivering the Sustainable Development Goals and the Rio conventions in the Sahel. Biodiversity is the foundation of the Great Green Wall in many ways, determining soil productivity and water cycles and providing the foundation for risk management and resilient ecosystems. The Great Green Wall can make a major contribution to achieving many of the Sustainable Development Goals.

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.

The West African Sahel is very vulnerable to the effects of climate change, due to land degradation, dependence on rainfed farming, political instability, poor governance, food insecurity, terrorism, poor infrastructure, and limited technical capacity. This has particular impacts on the agricultural sector (Sissoko et al. 2011; Zougmoré et al. 2016).

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.

The Lawra district of the Upper West region was selected as the case study. This study compared crop yields for FMNR and non-FMNR farmers. FMNR farmers are classified as having at least 8 trees per acre, with an average of 13 trees per acre (33 per ha) and a maximum of 40. Non-FMNR farmers are classified as having between 1 and 7 trees per acre, with an average of 5.Qualitative (focus group discussion) and quantitative (household survey) data were collected in April to May 2019. Over 500 households were interviewed in both CIKOD intervention communities and control sites.

Influenced by international trends, as well as in response to population, climate, resource and development needs, the standards, norms, mechanisms and incentives in natural resources law at the national level have evolved in recent years. Natural resources laws are influenced by developments in the international arena, either through international treaties that are binding or through ‘soft law’ instruments that are not legally binding but nevertheless have widespread adherence among governments, or that provide principles that guide and shape national legislation.

A review of needs at various scales for tools and processes that can help countries and stakeholders meet emerging challenges, address increasing degradation of and competition for resources, support the sustainable use and restoration of land and water resources, and ensure resilient ecosystems.

Desertification, land degradation and drought affect more than 2 billion people and the situation might worsen due to the unsustainable use of soil and water under present scenarios of climate change. The UNCCD 10-year strategy points out the importance of science, knowledge sharing systems and awareness raising to support policymakers in reversing this trend. Sustainable land management practices, including sustainable agriculture, provide important local, regional and global benefits.

Under the present conditions of climate change and the growing scarcity of productive natural capital such as arable land and water, The strategy aims to rally a global coalition to deliver benefits for people and ecosystems everywhere and generate downto-earth responses to some of the major international challenges of our time.

The world’s drylands are among the most vulnerable ecosystems on our planet. Desertification and land degradation are affecting huge land areas, jeopardizing the livelihoods of millions of people. Unsustainable management practices in dryland cultivation and pastoralism have given rise to widespread soil erosion, reduction of the biological production of soils, reduction of vegetation cover, and depletion of surface and groundwater resources.

The Arab region is a diverse one when it comes to sustainable development. In recent years and decades, we have seen both major success stories in prosperity and stability, but we have also witnessed tragic conflicts and wars. At the same time, the 22 countries of the region are bound together by a common history, language and culture. We share many similar challenges and opportunities. Instability and human insecurity are in no one’s interest.
