The study and use of traditional knowledge in agroecological contexts
The importance of researching and maintaining traditional knowledge is a concern within contemporary academic debates and public policies. Scientist of different disciplines have recognized this importance, indicating this is a broader interdisciplinary issue. Specifically, within the field of agroecological science, the concept of traditional knowledge is basic to the analysis of agroecosystems. This essay aims to analyze, within scientific papers, the approaches to traditional knowledge through agroecological studies. First, insights from traditional knowledge studies in socio-ecological systems are presented as a wider view. Secondly, papers that illustrate agroecological approach to traditional knowledge and the usage of participative research methodologies are systematically reviewed to the forward development of five propositions: 1) traditional knowledge dynamics, 2) importance of traditional knowledge and professional’s ethics, 3) methodologies used for traditional knowledge gathering, 4) subjects of study in agroecological and traditional knowledge studies and 5) the integration of traditional knowledge with scientific knowledge.The importance of researching and maintaining traditional knowledge is a concern within contemporary academic debates and public policies.

Estudio y uso del conocimiento tradicional en contextos agroecológicos
The importance of researching and maintaining traditional knowledge is a concern
within contemporary academic debates and public policies. Scientist of different disciplines
have recognized this importance, indicating this is a broader interdisciplinary issue. Specifically,
within the field of agroecological science, the concept of traditional knowledge is basic
to the analysis of agroecosystems. This essay aims to analyze, within scientific papers, the
approaches to traditional knowledge through agroecological studies. First, insights from
traditional knowledge studies in socio-ecological systems are presented as a wider view.
Secondly, papers that illustrate agroecological approach to traditional knowledge and the
usage of participative research methodologies are systematically reviewed to the forward
development of five propositions: 1) traditional knowledge dynamics, 2) importance of
traditional knowledge and professional’s ethics, 3) methodologies used for traditional
knowledge gathering, 4) subjects of study in agroecological and traditional knowledge
studies and 5) the integration of traditional knowledge with scientific knowledge.La importancia de investigar y preservar el conocimiento tradicional es una preocupación
dentro de los debates académicos contemporáneos y para los hacedores de políticas
públicas. Científicos de diferentes disciplinas han reconocido esta importancia, indicando
que este es un tema interdisciplinario más amplio. Específicamente, dentro del campo de
la ciencia agroecológica, el concepto de conocimiento tradicional es básico para el análisis
de los agroecosistemas. Este ensayo pretende analizar, dentro de los artículos científicos,
los enfoques del conocimiento tradicional a través de estudios agroecológicos. En primer
lugar, las ideas de los estudios del conocimiento tradicional en sistemas socio ecológicos
se presentan como una visión más amplia. En segundo lugar, los artículos que ilustran el
enfoque agroecológico del conocimiento tradicional y el uso de metodologías de investigación
participativa son revisados sistemáticamente para el desarrollo de cinco proposiciones:
1) dinámica del conocimiento tradicional, 2) importancia del conocimiento tradicional
y ética profesional, 3) metodologías utilizadas para la recopilación de conocimiento,
4) temas abordados en estudios de conocimiento agroecológico y tradicional y 5) la integración
del conocimiento tradicional con el conocimiento científico.Fil: Alzate, Carolina.

Moving carbon between spheres, the potential oxalate-carbonate pathway of Brosimum alicastrum Sw.; Moraceae.
Aims The Oxalate-Carbonate Pathway (OCP) is a biogeochemical process that transfers atmospheric CO2 into the geologic reservoir as CaCO3; however, until now all investigations on this process have focused on species with limited food benefits. This study evaluates a potential OCP associated with Brosimum alicastrum, a Neotropical species with agroforestry potential (ca. 70–200 kg-nuts yr−1), in the calcareous soils of Haiti and Mexico. Methods / results Enzymatic analysis demonstrated significant concentrations of calcium oxalate (5.97 % D.W.) were associated with B. alicastrum tissue in all sample sites. The presence of oxalotrophism was also confirmed with microbiological analyses in both countries. High concentrations of total calcium (>7 g kg−1) and lithogenic carbonate obscured the localised alkalinisation and identification of secondary carbonate associated with the OCP at most sample sites, except Ma Rouge, Haiti. Soils adjacent to subjects in Ma Rouge demonstrated an increase in pH (0.63) and CaCO3 concentration (5.9 %) that, when coupled with root-like secondary carbonate deposits in Mexico, implies that the OCP does also occur in calcareous soils. Conclusions Therefore this study confirms that the OCP also occurs in calcareous soils, adjacent to B. alicastrum, and could play a fundamental and un-accounted role in the global calcium-carbon coupled cycle
