Outputs (results) on individual tree density, canopy cover, and estimated tree carbon stock in Rwanda using aerial images of 2008, published in "Mugabowindekwe, M., Brandt, M., Chave, C., Reiner, F., Skole, D. L, Kariryaa, A., Igel, C., Hiernaux, P., Ciais, P., Mertz, O., Tong, X., Li, S., Rwanyiziri, G., Dushimiyimana, T., Ndoli, A., Uwizeyimana,...
Article
This study was developed in the context of the Provision of Adequate Tree Seed Portfolios (PATSPO) initiative in Ethiopia. PATSPO aims to strengthen the existing tree-seed system by ensuring access to high-quality tree germplasm. Here, we estimate the socioeconomic impact of establishing a breeding seedling orchard (BSO) and distributing quality pl...
Preprint
Full-text available
Trees sustain livelihoods and mitigate climate change, but a predominance of trees outside forests and limited resources make it difficult for many developing countries to conduct frequent nation-wide inventories. Here, we propose a rapid and accurate approach to map the carbon stock of each individual tree and shrub at the national scale of Rwanda...
Article
Current tree-planting initiatives are not always successful in achieving their stated targets of biodiversity conservation, climate change mitigation and human livelihood improvement. This is in part due to a lack of attention to the proper sourcing of the tree seeds and seedlings that are used. In this working paper, we explore these sourcing issu...
Book
Full-text available
The work of the CGIAR Research Program on Forests, Trees and Agroforestry (FTA) on tree seed systems — the authors’ shorthand for the means through which growers obtain access to tree-planting materials, either seeds or seedlings — has sought to address significant constraints in the diversity and genetic quality of the tree seeds and seedlings tha...
Article
Full-text available
The Ethiopian government has set ambitious landscape restoration targets to achieve by 2030. Here, we describe a novel approach to identify landscapes to prioritize for tree-planting-based restoration interventions in the country. Our approach, which has several advantages compared to existing prioritization methods, starts with current land use pa...
Article
A systematic approach to tree planting and management globally is hindered by the limited synthesis of information sources on tree uses and species priorities. To help address this, the authors ‘mined’ information from 23 online global and regional databases to assemble a list of the most frequent tree species deemed useful for planting according t...

Abstract Coffee leaf rust (CLR), caused by the fungal pathogen Hemileia vastatrix, has plagued coffee production worldwide for over 150 years. Hemileia vastatrix produces urediniospores, teliospores, and the sexual basidiospores. Infection of coffee by basidiospores of H. vastatrix has never been reported and thus far, no alternate host, capable of...
Book
Biodiversity supports sustainable food production, although recognition of its roles has been relatively neglected in the sustainable intensification literature. In the current study, the roles of biodiversity in sustainable food production are considered, assessing how these roles can be measured, the current state of knowledge and opportunities f...
Chapter
Supporting the diversification of African agricultural systems by the further integration of nutritious, perennial ‘new and orphan crops’ (NOC) is seen as an important means to address malnutrition in Africa. The approach may be of particular relevance in the context of climate change, with the diversification of food systems possibly supporting mo...

Rethinking the logic of institutional environments aiming to facilitate agroforestry smallholders in economic development, this article compares smallholder input supply systems for crop and tree seeds in sub‐Saharan Africa and reflects on two basic challenges: (1) how to develop a large number of relevant tree crops for different agroecologies, (2...
Article
Full-text available
Planting trees to sequester carbon dioxide mitigates climate change, but it has been contended that insufficient attention is given to the quality of the germplasm established in afforestation/reforestation programmes, limiting sequestration opportunities. To understand current practices in the choice, sourcing and delivery of tree planting materia...
Article
Full-text available
Abstract Forest and woodland landscape restoration is a key undertaking of renewed interest for forestry and conservation practitioners, but is hampered by the lack of information on the distributions of tree species and of patterns of intra-specific genetic variation. Through the first meta-analysis of its type, we here tested the utility of a hig...
Article
Full-text available
We performed a rapid global assessment of the availability and robustness of conservation strategies for ecoregions. In some cases this involved assessment of large regions composed of multiple ecoregions. We found ecoregion and regional conservation strategies through internet searches, guided by Google Search Engine, Google Scholar, literature ci...

Full-text available
We assess progress toward the protection of 50% of the terrestrial biosphere to address the species-extinction crisis and conserve a global ecological heritage for future generations. Using a map of Earth's 846 terrestrial ecoregions, we show that 98 ecoregions (12%) exceed Half Protected; 313 ecoregions (37%) fall short of Half Protected but have...

Fire is a major factor shaping the distribution of vegetation types. In this study, we used a recent high resolution map of potential natural vegetation (PNV) types and MODIS fire products to model and investigate the importance of fire as driver of vegetation distribution patterns in Ethiopia. We employed statistical modeling techniques to estimat...

Article
Full-text available
Countries in eastern Africa have set aside significant proportions of their land for protection. But are these areas representative of the diverse range of species and habitats found in the region? And do conservation efforts include areas where the state of biodiversity is likely to deteriorate without further interventions? Various studies have a...
Article
Full-text available
This document provides a short description of the methodology used to create a harmonized natural vegetation map for eastern Africa. The map was derived from the potential natural vegetation map for eastern Africa developed by the VECEA (Vegetation and Climate change in East Africa) project. This map offers the hitherto most detailed description of...
Raw Data
An overview of 1,022 plant species that are documented in species assemblages for the potential natural vegetation map of eastern Africa (http://vegetationmap4africa.org). For each the species, a list is provided of the vegetation types in which a species is expected to be present. The distribution of each species in vegetation types for each speci...

The map of potential natural vegetation of eastern Africa, gives the distribution of potential natural vegetation in Ethiopia, Kenya, Tanzania, Uganda, Rwanda, Burundi, Malawi and Zambia. The map distinguishes 48 vegetation types, divided in four main vegetation groups: 16 forest types, 15 woodland and wooded grassland types, 5 bushland and thicket...

Full-text available
The paper reviews tree seed and seedling supply systems in sub-Saharan Africa, Asia and Latin America. Across these regions, the review found that some of the germplasm supply systems do not efficiently meet farmers’ demands and environmental expectations in terms of productivity, species and genetic diversity. In some countries, germplasm used is...
Article
Full-text available
Agroforestry and livestock-keeping both have the potential to promote anthropogenic climate change-resilience, and understanding how they can support each other in this context is crucial. Here, we discuss relevant issues in East Africa, where recent agroforestry interventions to support livestock-keeping have included the planting of mostly-exotic...

Choosing suitable agro-forestry species, varieties and seed sources for future climates with ensemble approaches
Conference Paper
Full-text available
Adaptation to future climates requires that we plan interventions on the basis of reliable models for predicting how existing and potential future agroforestry systems will perform. Because process-based models are currently only available for a limited number of trees, species distribution modelling (SDM) is currently the most sophisticated approa...
