Regreening Africa enhances resilience in the Sahel and Horn of Africa by addressing climate change, land degradation, and food insecurity. Through a broad partnership network, the initiative scales context-appropriate land restoration by integrating trees and sustainable practices into farming and pastoral systems. Phase II expands efforts in Somalia, Ethiopia, Senegal, Nigeria, Ghana, Mali, and Niger, focusing on systems scaling for transformative change. Building on Phase I, this phase promotes agroforestry, FMNR, soil and water conservation, soil health improvement, grazing management, and energy-efficient cookstoves to boost land productivity and resilience, particularly in rangeland and mixed landscapes.

Agroforestry Training Manual
This manual is a practical training resource developed to strengthen the capacity of extension agents and farmers in implementing agroforestry practices in Rwanda. Produced under the project Promoting Climate-Smart Agriculture for Improved Rural Livelihoods and Climate Resiliency in the Climate-Vulnerable Eastern Province of Rwanda, the manual provides technical guidance on integrating trees, crops, and livestock to enhance productivity, resilience, and environmental sustainability. The publication covers four main areas: agroforestry principles, systems and suitable species; tree nurseries and seedbeds; tree planting and management; and agroforestry products and services. It presents common agroforestry systems practiced in Rwanda, including woodlots, alley cropping, contour tree planting, fruit orchards, silvopastoral systems, home gardens, apiculture, aquasilviculture, and sericulture. The manual also provides practical recommendations on nursery establishment, seed handling, seedling management, tree planting techniques, pruning, thinning, coppicing, and tree protection. Furthermore, it highlights the economic and environmental benefits of agroforestry, including fruit production, tree seed enterprises, fodder, timber, fuelwood, honey production, erosion control, soil fertility improvement, climate change adaptation, biodiversity conservation, and restoration of degraded lands. Designed as a hands-on training tool, the manual aims to promote climate-smart agriculture, improve rural livelihoods, and support sustainable land management through increased adoption of agroforestry practices.
Climate-growth relationships of Daniellia oliveri (Rolfe) Hutch. & Dalziel in the Sudanian zone of Mali, West Africa
Tree rings depend on seasonal variation in radial tree growth. Where they can be identified, their interannual variation may reflect climate variability. Compared to its use in temperate and boreal regions, tree-ring analysis has been less applied in tropical Africa, with weaker seasonality. Daniellia oliveri often forms the tallest trees in agroforestry parklands of the Sudanian savanna zone of Mali but its growth response to climate (rainfall, temperature) variability has not been documented. We analyzed six stem disks of D. oliveri and used standard dendrochronological methods to process the samples. Contrary to earlier literature likely based on more humid parts of the species distribution range, D. oliveri formed distinct growth ring boundaries in our study area. The mean annual radial growth was 2.73 ± 0.56 mm. All measured tree-ring series were successfully cross-dated with a GLK (Gleichläufigkeit) value of 76.3 ± 5.6. The final tree-ring chronology covers the period 1909-2021. After removing age-related growth trends, the tree-ring width index showed a significant relationship with records of annual rainfall (r2 = 0.46, n = 100 years, p < 0.001). The relationship between wet-season (June to September) precipitation and the residual chronology was slightly higher (r2 = 0.50, n = 100 years, p < 0.001). However, no significant correlation was found for temperature. These results imply that D. oliveri can be successfully used for dendrochronological studies with relevance for the management and restoration of the ecosystems in the Sudanian zone of West Africa, where long-term rainfall records are scarce.

Exploring knowledge and uses of Moringa oleifera and understanding its cultivation constraints and proposed solutions: a case from Bangladesh
Multipurpose trees, like the moringa (Moringa oleifera Lam.), have become extremely popular in an attempt to reduce food, nutritional, and economic instability. The significant benefits of moringa’s leaves, pods, seeds, roots, and flowers are used in a wide range of commercial fields, including medicine, cosmetics, food, animal feed, water purification, and more. We applied a questionnaire-based survey to reveal the uses, problems and solutions related to the knowledge, uses and constraints of moringa in the region of Chapainawabganj and Kushtia districts in Bangladesh. Including the easiest propagation process and the lowest cultivation costs, year-round flowering, and production provide moringa with a wide window of opportunity. Besides using regular pruning of moringa branches, respondents make trees bushy to increase fruit and leaf production. Respondents from both regions opined that moringa has a good market value, increases family income, increases opportunity for fallow land utilization, enhances employment opportunities, and is known as a nutritive and multipurpose tree. We were pleased to find that moringa output regularly exceeded previous production records in Bangladesh from 2014–16 to 2020–21. Furthermore, our survey shows that a 5-year-old moringa tree provides a satisfactory yield per season with its high market price and demand. Despite the extensive use of moringa fruits and leaves by respondents, its commercial potential remains largely undeveloped and unknown to them. Constraints like limited scientific knowledge and technological infrastructure are the reasons why the elusive potential of moringa in Bangladesh persists. There is ample opportunity to enhance moringa production via effective management techniques, which will satisfy community demand and create market opportunities both locally and internationally. As a result, smallholder farmers’ livelihoods and food and nutritional security can be improved.
