The importance of agricultural land uses in the provision of ecosystem services. A gender perspective in Nicaragua [PDF]

, 2019
There is a link between agricultural systems (crops of basic grains, livestock, agroforestry systems for coffee and cocoa) and poor populations in rural areas. These land uses not only provide food, but also other ecosystem services (SE).

Spatial variation in current and historical management of Arabica coffee across forests in its indigenous distribution

PLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 215-228, January 2025.
Arabica coffee grows in the forests and woodlands of Ethiopia. These Arabica coffee populations contain a reservoir of the highest genetic variation of this species, which is extremely valuable from a biodiversity conservation and coffee breeding point of view. Knowledge about the distribution of these populations, including how and to what extent they

Analysis of the interactions of shade trees on coffee leaf diseases and coffee yield in complex agroforestry systems [PDF]

, 2019
In complex coffee-based agroforestry, quantifying interactions within the agrosystem that impact on coffee disease regulation and on coffee yield is a major stake to design sustainable cropping systems.

Guadeloupe and Haiti's coffee genetic resources reflect the crop's regional and global history

PLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 245-262, January 2025.
Despite strong historical declines, Guadeloupe and Haiti's coffee sectors remain important to rural communities' livelihood and resilience. Coffee also holds value as part of the islands' historical legacy and cultural identities. Furthermore, it is often grown in agroforestry systems providing important ecosystem services, which will become more ...

Short-range-order minerals as powerful factors explaining deep soil organic carbon stock distribution: the case of a coffee agroforestry plantation on Andosols in Costa Rica [PDF]

SOIL, 2019
Soil organic carbon (SOC) constitutes the largest terrestrial C stock, particularly in the Andosols of volcanic areas. Quantitative information on distribution of SOC stocks is needed to construct a baseline for studying temporal changes in SOC.

Dynamics, Monitoring, and Forecasting of Tephra in the Atmosphere

Reviews of Geophysics, Volume 62, Issue 4, December 2024.
Abstract Explosive volcanic eruptions inject hot mixtures of solid particles (tephra) and gasses into the atmosphere. Entraining ambient air, these mixtures can form plumes rising tens of kilometers until they spread laterally, forming umbrella clouds. While the largest clasts tend to settle in proximity to the volcano, the smallest fragments, commonly
