Potentials of native plant species in Agroforestry systems for reduction of greenhouse gas emissions and improvement of local environmental and communities‘ life conditions
This document discusses a study on the potentials of native plant species in agroforestry systems in Colombia. The study aims to quantify greenhouse gas emissions from small-scale farming, analyze how agroforestry with native plants can reduce emissions, and promote cultivation of endangered native species. It notes lack of local strategies, depletion of traditional knowledge, and lack of research on agroforestry potentials. Preliminary results found endangered and disappeared native medicinal plants in two municipalities. The study will involve community interviews, gas sampling, and designing a homegarden model to evaluate impacts on livelihoods and projections for food/medicine production and greenhouse gas mitigation.

3. 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
5. Preliminary results
Campo Hermoso
Zetaquira
• 15 endangered medicinal
species
9 native species
• 20 dissapeared medicinal
species
7 native species
• Urtica dioica L. popularity
(IUV)
• 7 endangered medicinal
species
3 native species
• 13 dissapeared medicinal
species
6 native species
• Ruta graveolens L.
popularity
6. 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 multipurpose 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.
7. 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.
