CGIAR Research Program 6: Forests, Trees and Agroforestry: Livelihoods, Landscapes and Governance por Center for International Forestry Research, World Agroforestry Centre, International Center for Tropical Agriculture

“…CRP6 is designed to make a significant contribution toward the vision and strategic objectives articulated in the CGIAR’s Strategic Results Framework by: 1. enhancing the contribution of forests, agroforestry and trees to production and incomes of forest-dependent communities and smallholders; 2. conserving biodiversity, including tree genetic diversity, through sustainable management and conservation of forests and trees; 3. maintaining or enhancing environmental services from forests, agroforestry and trees in multifunctional and dynamic landscapes; 4. reducing emissions of greenhouse gases and augmenting carbon stocks through better management of forest- and tree-based sources while increasing local and societal resilience through forest-, agroforestry- and tree-based adaptation measures; and 5. promoting the positive impacts and reducing the negative impacts of global trade and investment as drivers of landscape change affecting forestlands, agroforestry areas, trees and the well-being of local people. …”

Variability of soil surface characteristics in a mountainous watershed in Valle del Cauca, Colombia: Implications for runoff, erosion, and conservation por Guzmán, Christian D., Hoyos Villada, Fanny, Silva, Mayesse Aparecida da, Zimale, Fasikaw A., Chirinda, Ngonidzashe, Botero, César, Morales Vargas, Amalia, Rivera, Baudelino, Moreno, Pedro, Steenhuis, Tammo S.

“…The lowest infiltration rate average (2.3 cm hr−1) exceeded the estimated erosive regional precipitation intensity (∼2.5 cm hr−1) about 60% of the time, while the median infiltration rate (10 cm hr−1) exceeded rainfall intensities 94% of the time, indicating that infiltration excess and saturation excess runoff mechanisms are both present. …”

Soil respiration response to reductions in maize plant density and increased row spacing (Southeast pampas, Argentina) por Lewczuk, Nuria, Picone, Liliana, Echarte, María Mercedes, Alfonso, Cecilia, Rizzalli, Roberto Héctor, Echarte, Laura

“…However, the combination of this practice with low-yield potential genotypes that exhibit low stability to changes in resource availability can increase CO2 emissions per unit of grain yield. These findings contribute to a better understanding of the impacts of management practices on soil respiration and, consequently, on carbon cycling within agricultural ecosystems.…”
