Learning resources

The World Agroforestry Centre has developed a range of learning resources, most of which are publicly available or downloadable. In many cases, we also have printed versions of these resources.

A global spectral library to characterize the world's soil

This journal article on Soil, provides a highlight on ecosystem services that supports human health and habitation, stores carbon and regulates emissions of greenhouse gases. Unprecedented pressures on soil from degradation and urbanization are threatening agro-ecological balances and food security. It is important that we learn more about soil to sustainably manage and preserve it for future generations.

Global Soil Biodiversity Atlas

This book was published in 2016 and it gives an overview of soil. Soils and the life within them were in the spotlight globally. Therefore, an international group of experts and scientists from the European Commission’s Joint Research Centre (JRC), in close collaboration with colleagues from the Commission’s Directorate-General for the Environment and the Global Soil Biodiversity Initiative, have produced the first ever Global Soil Biodiversity Atlas. Soils are vital for human survival and underpin many sectors of our economy. It is estimated that 99 % of the world’s food comes from the terrestrial environment. But soils are also home to over a quarter of global biodiversity. Millions of soil-dwelling organisms promote essential ecosystem services – from plant growth to food production. They support biodiversity, benefit human health, promote the regulation of nutrient cycles that in turn influence climate, and represent an unexplored capital of natural sources. Knowledge of soil life is growing continuously due to recent technological advances and awareness of its value.

Evaluating the utility of mid-infrared spectral subspaces for predicting soil properties

Sila A M, Pokhariyal G P, Shepherd K D (2016)
This article proposes four methods for finding local subspaces in large spectral libraries. The proposed four methods include (a) cosine angle spectral matching; (b) hit quality index spectral matching; (c) self-organizing maps and (d) archetypal analysis methods. Then evaluate prediction accuracies for global and subspaces calibration models. These methods were tested on a mid-infrared spectral library containing 1907 soil samples collected from 19 different countries under the Africa Soil Information Service project. Calibration models for pH, Mehlich-3 Ca, Mehlich-3 Al, total carbon and clay soil properties were developed for the whole library and for the subspace. Root mean square error of prediction was used to evaluate predictive performance of subspace and global models

By-laws formulation and enforcement in natural resource management: lessons from the highlands of eastern Africa

Mowo J, Adimassu Z, Kamugisha R, Lyamchai C, Masuki K, Tanui J(2016)
This learning resource gives us a clear picture on degradation of land, water and vegetation in the highlands of eastern Africa is on the increase in the face of the enforcement of natural resource management (NRM) policies and related by-laws. In this study, reasons behind the limited contribution of NRM by-laws in arresting degradation of natural resources in the highlands of Ethiopia, Tanzania and Uganda are presented, and opportunities to improve effectiveness identified. Using key informants’ interviews, focus group discussions, workshops, case studies and literature review, it is shown that inadequate community participation in the process of by-laws formulation and enforcement is the main reason for the ineffectiveness of most NRM by-laws in the three countries. When communities are fully involved in the process of NRM by-laws formulation and enforcement and both conventional and indigenous by-laws enforcement mechanisms are adopted, incidences of abuse of natural resources were reduced by as much as 50% in some of the study sites.

The Land-Potential Knowledge System (LandPKS): mobile apps and collaboration for optimizing climate change investments

Herrick J E, Barrios E, Beh A, Bouvier I, Coetzee M, Dent D, Elias E, Hengl T, Karl J W, Liniger H, Matuszak J, Ndungu L W, Neff J C, Obersteiner M, Shepherd K D, Urama K C, van den Bosch R, Webb N P (2016)
Massive investments in climate change mitigation and adaptation are projected during coming decades. Many of these investments will seek to modify how land is managed. The return on both types of investments can be increased through an understanding of land potential: the potential of the land to support primary production and ecosystem services, and its resilience. A Land-Potential Knowledge System (LandPKS) is being developed and implemented to provide individual users with point-based estimates of land potential based on the integration of simple, geo-tagged user inputs with cloud-based information and knowledge.

Training in Agroforestry - a Toolkit for Trainers
Peter Taylor and Jan Beniest (2003)
This toolkit has been developed to assist trainers and educators in planning, organizing and implementing training in agroforestry and is based on the participatory curriculum development approach and the Centre's long experience in agroforestry training and education. It consists of a 4-ring binder developed into three parts; participatory curriculum development, ten key elements related to training course design and useful resources for agroforestry training and education. The ten key elements are adult learning concepts, stakeholder analysis, training needs assessment, setting aims and objectives, choosing and using content, methods and materials, teaching and learning methods, training materials, lesson planning, evaluation and assessment, training event organization.
