Bioclimatic modelling of current and projected climatic suitability of coffee (Coffea arabica) production in Zimbabwe

Mapping Spatio-Temporal Changes in Climatic Suitability of Corn in the Philippines under Future Climate Condition

“…The result of this study conforms with the previous study conducted by Salvacion and Martin (2016) where changes in rainfall and temperature resulted to decrease in climatic suitability of corn in the province of Isabela, Philippines. In addition, it also agrees with different studies elsewhere that the effect of climate change on suitability varies across area (Bonfante et al 2015, Chemura et al 2015, Jayathilaka et al 2012, Lane, Jarvis 2007, Ovalle-Rivera et al 2015, RamirezCabral et al 2016, Wang et al 2015, Zabel et al 2014. On the other hand, it also shows that the effect of climate change on crop suitability varies across time (months) or depending on the start of cropping period.…”

“…First, climate change affects crop yield because changes in rainfall and temperature affect crop growth and development (Antón et al 2013, Ewert et al 2015, Holzkämper et al 2015, Islam et al 2012, Kim et al 2016, Ko,Ahuja 2014, Yan-Ling et al 2012. Second, changes on existing climate in an area can alter crop suitability in the region (Bonfante et al 2015, Chemura et al 2015, Jayathilaka et al 2012, Lane, Jarvis 2007, Ovalle-Rivera et al 2015, Ramirez-Cabral et al 2016, Wang et al 2015, Zabel et al 2014.…”

Smallholder coffee terroirs of Rwanda : linking local to global trade through geographical characterization

“…Buberuka highlands (BH) will experience a possible terroir gain due to an increase in temperature by 2050. The changes in climatic variables will affect coffee terroirs which means that it will become more difficult and expensive to achieve high quality and high yields (Chemura et al, 2016) in coffee terroirs predicted to become marginal, while it will become easier for those future terroirs that will become climatically favoured. It is important that farmers in current coffee terroirs that will turn marginal revise their strategies in the face of climate change.…”

“…It is important that farmers in current coffee terroirs that will turn marginal revise their strategies in the face of climate change. This will include adopting new coffee varieties and agro-economic models that are suited to climate change (Chemura et al, 2016) with greater tolerance of high temperatures and altered pest and disease pressures (Schroth et al, 2009). The Government of Rwanda should consider renewing the national policy that promotes weather-based insurance (Akter, Krupnik, Rossi, & Khanam, 2016;Rao, Gopinath, Prasad, Prasannakumar, & Singh, 2016).…”

“…To produce a specialty coffee, it is important to take into consideration location attributes such as topography, soil type, and climate such as rainfall distribution and seasonal temperature variability (Chemura, Kutywayo, Chidoko, & Mahoya, 2016;Joët et al, 2010;Ovalle-Rivera et al, 2015). Altitude determines microclimate in which coffee is grown and for the southern hemisphere (where Rwanda is located), fields with a face slope oriented to the south receive a smaller amount of solar radiation than do those oriented to the north (Bertrand et al, 2012).…”
