Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica
(2020)
Coffee leaf rust is a polycyclic disease that causes severe epidemics impacting yield over several years. For this reason, since the 1960s, more than 20 models have been developed to predict different indicators of the ...
Development of an Open-Source Thermal Image Processing Software for Improving Irrigation Management in Potato Crops (Solanum tuberosum L.)
(2020)
Accurate determination of plant water status is mandatory to optimize irrigation scheduling
and thus maximize yield. Infrared thermography (IRT) can be used as a proxy for detecting
stomatal closure as a measure of plant ...
Long-term effects of shade and input levels on coffee yields in the Pacific region of Nicaragua
(CIRAD, Montpellier (France), 2020)
The suitability and profitability of coffee cultivation in Central America are at risk due to pest and disease outbreaks, price fluctuations and climate change. Proper shading is claimed to be one of the most promising ...
Siting Marine Protected Areas with Area Targets Protecting Rural Incomes, Fish Stocks, and Turtles in Costa Rica
(2020-04)
With many countries seeking to increase the area conserved in marine protected areas (MPAs) to achieve the Convention on Biodiversity’s protected area targets by 2020, we employ a bioeconomic model to determine which ...
Region-specific emission factors for Brazil increase the estimate of nitrous oxide emissions from nitrogen fertiliser application by 21%
(Elsevier, Ámsterdam, Países Bajos, 2020)
The use of synthetic nitrogen fertilisers is one of the most important land management practices proposed to improve crop and pasture productivity. The use of such fertilisers in excess can lead to greenhouse gas (GHG) ...
Policy Note: Policy Responses to Ensure Access to Water and Sanitation Services During COVID-19: Snapshots from the Environment for Development (EfD) Network
(2020)
This policy note provides a snapshot of water and sanitation measures implemented by governments in response to the COVID-19 pandemic in 14 countries in the Global South: Costa Rica, El Salvador, Guatemala, Honduras, ...
Radiation Interception, Conversion and Partitioning Efficiency in Potato Landraces: How Far Are We from the Optimum?
(MDPI, Basel (Switzerland), 2020-06)
Crop efficiencies associated with intercepted radiation, conversion into biomass and allocation to edible organs are essential for yield improvement strategies that would enhance geneticproperties to maximize carbon gain ...
Agroforestry governance for operationalising the landscape approach: connecting conservation and farming actors
(Springer, Berlín (Alemania), 2020-07)
The expansion and intensification of agriculture as well as the associated land clearing are threatening both biodiversity and
human wellbeing in tropical areas. Implementing agroforestry systems through a landscape ...
Shade tree Chloroleucon eurycyclum promotes coffee leaf rust by reducing uredospore wash-off by rain
(Elsevier, Ámsterdam (Países Bajos), 2020)
addition, may interact with environment. To better understand shade trees effects on coffee leaf rust (CLR), we
studied three disease stages separately: sporulation, uredospore wash-off by rain, and uredospore deposition ...
Measured ammonia emissions from tropical and subtropical pastures: A comparison with 2006 IPCC, 2019 Refinement to the 2006 IPCC, and EMEP/EEA (European Monitoring and Evaluation Programme and European Environmental Agency) inventory estimates
(American Dairy Science Association, Champaign, IL, EUA ; Elsevier, Ámsterdam, Países Bajos, 2020)
Agriculture is the largest source of ammonia (NH3) emissions. As NH3 is an indirect greenhouse gas, NH3 measurements are crucial to improving greenhouse gas emission inventory estimates. Moreover, NH3 emissions have wider ...
