“…In the mid-elevation zone of southwestern Mexico where we conducted our study, the general expectation from climate change, in addition to increased temperature, is reduced rainfall 19 , 20 , a pattern broadly in evidence for the past five years (Fig. S2 ).…”

“…4 b, we propose that a possible parameter driving the system to this initial bifurcation was recent increases in precipitation, as evidenced in local rainfall records (Fig. S2 ) and regional trends 19 . This could have propelled the system past a hysteretic phase space to where seasonal conditions dictated that the system jump to a high rust intensity equilibrium, represented conceptually in Fig.…”

“…Our observations of the rust dynamics themselves allow us to detect the general signals anticipating a critical transition, though the drivers may emerge from a complex system of dialectical interactions that must be considered in their whole 7 , 27 . The concept of critical slowing down thus may lend itself to application across coffee-growing regions, where predicted effects of climate change and other geographic conditions may differ 9 , 19 . Since the emergence of the rust outbreak, recommendations and protocols have been published for monitoring rust levels, potentially providing managers with regular data in changes in rust intensity for many areas 9 , 28 .…”

Critical transitions, sudden responses to slow changes in environmental drivers, are inherent in many dynamic processes, prompting a search for early warning signals. We apply this framework to understanding the coffee rust disease, which experienced an unprecedented outbreak in Mesoamerica in 2012–2013, likely a critical transition. Based on monthly infection data from 128 study quadrats in a 45-ha plot in southern Mexico from 2014 to 2020, we find that the persistent seasonal epidemic following the initial outbreak collapses in an evident subsequent critical transition. Characteristic signals of “critical slowing down” precede this collapse and are correlated with reduced rainfall, as expected from climate change, and planting of rust-resistant varieties, an ongoing management intervention. Recoveries from catastrophes may themselves be experienced as a critical transition and managers should consider the larger dynamical landscape for the possibility of subsequent transitions. Early warning signals could therefore be useful when evaluating mitigation effectiveness.

“…En estudios sobre el comportamiento del café ante las variaciones climáticas, Pham et al (2019) reportaron que los cambios climáticos influyen negativamente en el rendimiento y generan la pérdida de áreas óptimas de cultivo. Torres et al (2020) y Asfaw et al (2019) evidenciaron que, a mayores temperaturas, los ataques de broca y roya del café tienen importancia económica, por lo que el desplazamiento de las zonas productoras de café hacia pisos altitudinales superiores constituye una barrera natural para la mitigación de los efectos del cambio climático en la producción del café.…”

El objetivo de esta investigación fue establecer la relación del tamaño y el peso de los granos de café arábica (Coffea arabica L.) con respecto a cinco gradientes altitudinales, desde los 1.000 hasta los 1.800 m s. n. m., en el municipio de Toledo, departamento de Norte de Santander (Colombia). Se seleccionaron al azar cuatro fincas por gradiente y se analizaron las cosechas de 2017 y 2018, para un total de 40 observaciones. Por cada muestra se clasificaron 120 g de granos verdes según tamaño y peso con las zarandas n.º 18, 16 y 14, y se pesaron 50 granos verdes por muestra para determinar las tendencias por piso altitudinal. Los datos obtenidos se examinaron mediante análisis descriptivo, varianza y prueba t de Student. El mayor valor del tamaño de los granos retenidos en la zaranda 18 fue de 17,99 g ± 8,16 g (piso 2) y el menor fue de 12,87 g ± 5,30 g (piso 1); en la zaranda 16, el mayor valor fue de 87,30 g ± 18,60 g (piso 2) y el menor fue de 62,56 g ± 19,49 g (piso 1); en la zaranda 14, el valor mayor fue de 52,86 g ± 18,20 g (piso 1) y el menor fue de 28,60 g ± 10,10 g (piso 2), y en los residuos, el mayor valor correspondió al piso 5, con media de 16,03 g ± 10,63 g, y el menor valor al piso 3, con 8,82 g ± 3,54 g.

“…Since 2010, annual global production of robusta and arabica has increased by 3% and 2%, respectively [ 1 ]. Nevertheless, coffee production is threatened by several factors including: (a) climate change which may result in reduction of coffee yield and area climatically suitable for coffee by, e.g., favoring pests and diseases outbreaks [ 4 , 5 , 6 , 7 , 8 , 9 ]; and, (b) biodiversity loss which affects coffee agroecosystem resilience by reducing, e.g., biocontrol interactions [ 10 , 11 , 12 ].…”

Little is known on what impact shade trees have on the physiology of Coffea canephora (robusta coffee) under tropical humid conditions. To fill this gap, a field experiment was conducted in the Ecuadorian Amazon to investigate how growth, nutrition (leaf N), phenological state (BBCH-scale) and yield of 5-year-old robusta coffee shrubs are affected by the presence or absence of leguminous trees, the type (organic v conventional) and intensity of management. The experiment was a factorial 5 × 4 design with four cropping systems: intensive conventional (IC), moderate conventional (MC), intensive organic (IO) and low organic (LO), and with five shading systems in a split-plot arrangement: full sun (SUN), both Erythrina spp. and Myroxylon balsamum (TaE), M. balsamum (TIM), E. spp. (ERY) and Inga edulis (GUA). Three monthly assessments were made. Cherry yields of coffee shrubs under moderate shade (c. 25%) were similar to those under high light exposure. Coffee shrubs grown with either E. spp. or I. edulis were taller (+10%) and had higher leaf N concentrations (22%) than those grown without consistent shade. Unless receiving c. 25% of shade, coffee shrubs grown under organic cropping systems showed reduced growth (25%). No correlation was found between height, cherry yield and leaf N. Both shading and cropping systems affected leaf N concentration, also depending on phenological state and yield. Further research is needed to confirm our findings in the long-term as well as to elucidate how leguminous trees may induce physiological responses in robusta coffee under humid tropical conditions.
