Scenery• Lack of local plans and strategies – only isolated efforts• Lack of information on dimensions of losses because of
depletion of resources and global warming at local level (long heavy rains)
• Lack of research on potentials of Agroforestry systems• Depletion of traditional knowledge and native plants
resources, lack of strategies to maintain these species.• Lack of motivation of local community
Some effects of heavy rains
Zea mays subsp. mays
Preliminary resultsCampo Hermoso• 15 endangered medicinal
species 9 native species• 20 dissapeared medicinal
species 7 native species• Urtica dioica L. popularity
(IUV)
Zetaquira• 7 endangered medicinal
species 3 native species• 13 dissapeared medicinal
species 6 native species• Ruta graveolens L.
popularity
Main Objectives• To collect quantitative information on greenhouse gas (GHG)
emissions in tropical small scale farming systems of Boyacá, Colombia.
• To analyse the potential of agroforestry systems with native multi-purpose and medicinal plants to reduce GHG emissions.
• To promote the cultivation and conservation of native plant species, especially endangered species.
• To add benefits to local production of food, medicine and to improve economy.
Hypotheses• The potential of Agroforestry systems with cultivation
of introduced medicinal plant species is equal to Agroforestry systems with cultivation of native species in terms of mitigation of Green House Gas emissions.
• Native multipurpose and medicinal plant species are often not cultivated in Agroforestry systems due to the lack of productivity.
• Lack of knowledge of the productivity that native and multipurpose medicinal plant species can offer to the local economy has limited investments in projects related to the cultivation of these species.
Methods
Productivity projections-Food production?-Medicinals production? -Influence on local economy? -Potentials off GHG mitigation?
Evaluation of impact on livelihoods
-Design of local homegarden model with selected species/ based on local necessities (community and environment) -Promotion of cultivation of the homegarden model in comunal plots and within local schools
Design of homegarden
model
-Selection of plots with agroforestry systems and selected species -Structured interviews -Analysis of fluxes of gases-Sampling of gasses -Statistical analyses
Sampling and collection of data
-Introduction of the project-Survey-Semi-structured Interviews-Data analyses-Selection of species -local interest and necessities--Previous results
Introduction and diagnostics
