The economic potential of fruit trees as shade in blue mountain coffee agroecosystems of the Yallahs River watershed, Jamaica W.I.

Abstract Studies in coffee agroecosystems often focus on the conservation and environmental benefits of this managed novel habitat, but rarely examine the socioeconomic benefit of the shade tree products themselves to coffee farmers. An examination of Blue Mountain coffee farmers along an elevation gradient within the Yallahs River watershed saw several tree species emerge as i...

Integrating local knowledge with tree diversity analyses to optimize on-farm tree species composition for ecosystem service delivery in coffee agroforestry systems of Uganda

Abstract Coffee agroforestry systems deliver ecosystem services (ES) critical for rural livelihoods like food but also disservices that constrain livelihoods like fostering coffee-pests. Since such ES are tree-based, maximizing ES and limiting constraints requires knowledge on optimizing on-farm tree composition especially trees adapted to local conditions. The study was in thr...

Shade trees decrease pest abundances on brassica crops in Kenya

Abstract Agroforestry practices may mitigate the current loss of biodiversity and ecosystem services due to deforestation and agricultural intensification. To examine the effects of agroforestry on the ecosystem service of pest regulation, we assessed pest abundances and biological control potential in shaded and open kale (Brassica oleracea L. acephala) fields in Western Kenya...

Design-consistent model-based variances with systematic sampling: a case study with the Danish national Forest inventory

To gauge, whether variances in density estimates computed under an assumption of a simple random sampling (SRS) are inflated – when the actual design ensures a spatial balance, we obtained design-consistent, model-based estimators from simulations with replicate samples and anticipated data. Anticipated data is the sum of model-based predictions and a random residual error. Two designs are emplo...

Information needs of next-generation forest carbon models: Opportunities for remote sensing science

Forests are integral to the global carbon cycle, and as a result, the accurate estimation of forest structure, biomass, and carbon are key research priorities for remote sensing science. However, estimating and understanding forest carbon and its spatiotemporal variations requires diverse knowledge from multiple research domains, none of which currently offer a complete understanding of forest car...

Current status of Landsat program, science, and applications

Formal planning and development of what became the first Landsat satellite commenced over 50 years ago in 1967. Now, having collected earth observation data for well over four decades since the 1972 launch of Landsat-1, the Landsat program is increasingly complex and vibrant. Critical programmatic elements are ensuring the continuity of high quality measurements for scientific and operational inve...

Estimates of willingness to accept compensation to manage pine stands for ecosystem services

Publication date: May 2019Source: Forest Policy and Economics, Volume 102Author(s): Edward Mutandwa, Robert K. Grala, Daniel R. PetroliaAbstractMany ecosystem services are often overlooked in active management of private forests leading to their production below the levels preferred by the society. This study used the contingent valuation method (CVM) to estimate willingness to accept (WTA) compen...

Soil carbon stock in olive groves agroforestry systems under different management and soil characteristics

Abstract The atmospheric concentrations of greenhouse gases have increased to unprecedented levels during last decades, raising concerns about their effect on climate change. Agriculture and land use change play an important role in atmospheric CO2 emission and fixation, especially by affecting the soil carbon (C) storage. In this context, agroforestry systems (AFSs) could play a...

‘Nothing was left’: Flash floods, landslides hit Indonesia’s Papua region

JAYAPURA/JAKARTA — Rain-triggered flash floods and landslides that struck Indonesia’s easternmost province this past weekend have killed nearly 90 people and driven thousands from their homes. The country’s disaster mitigation agency has cited human-caused deforestation as having exacerbated the scale of the damage. The flooding and mudslides destroyed buildings and roads in several areas of...

Forests scramble to absorb carbon as emissions continue to increase

Forests around the world are absorbing more carbon dioxide from the atmosphere, but they still can’t keep up with the sheer volume of the global-warming gas being emitted through human activity, a new study has found. “Intact forests are playing a large role in absorbing the CO2 we’re emitting,” said Benjamin Gaubert, the lead author […]...
