Pour que la recherche ait un impact, la science a besoin de canaux de communication clairs pour aller droit au but. Ilmu pengetahuan membutuhkan saluran komunikasi yang jelas untuk mencapai tujuan, jika ingin dampaknya terlihat. CIFOR—ICRAF publishes over publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more — in multiple languages. Science needs clear communication channels to cut through the noise, if research is to have any impact. We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises.

Preliminary results of a field study in Pucallpa, Peruvian Amazon, to determine the establishment of six native forest tree species of economic value on degraded areas abandoned after intensive past agricultural use are reported. Study sites were on slash-and-burn farms partially covered with abandoned agricultural areas on Ultisols dominated by invading vegetation mainly composed of Imperata brasiliensis, Rottboellia cochinchinensis and Baccharis floribunda. Tree species used in the trials were: Schizolobium amazonicum, Tabebuia serratifolia, Calycophyllum spruceanum, Terminalia oblonga, Amburana cearensis and Cedrelinga catenaeformis. These six species were planted in three degraded habitats characterised by the presence of one of the above weed species. After 13 months, Schizolobium amazonicum was the best adapted in the three experimental treatments, followed by Tabebuia serratifolia and Calycophyllum spruceanum. Habitats dominated by Baccharis floribunda offered comparatively better conditions for tree establishment and initial growth. Publication year Authors Soudre, M.

Adaptability of six native forest tree species to degraded lands in Pucallpa, Peruvian Amazon

The objective of this study implemented in the Peruvian Amazon around the city of Pucallpa was to determine possible use of Inga edulis to control some weed species e. Imperata brasiliensis and how different agricultural practices influence weed occurrence. The study evaluated four treatments as follows: 1 natural fallow; 2 cropping system with cassava; 3 planted fallow with Inga edulis; 4 planted fallow with I. Weed biomasses were measured at 3, 6, 9, 13, 17, 20, 24, 28 and 32 months after fallow initiation. Weed samples were enumerated by counting the number of weeds by species in each subplot. On the research plot, about 20 most frequent weed species were determined. Highest frequency had Imperata brasiliensis; Aboveground biomass reached Our results showed that all four treatments led to successful control of grass weed species. But because of the poor development of Inga trees on severally degraded soil, the trees could not suppress the weeds by shading. The trees would probably need more time to prove this ability.
