“…The disease kills coffee bushes so that, very soon after its detection on-farm, farmers will experience complete loss of income from coffee. Yields decline rapidly; a 77% loss in yield of robusta coffee at the national level in Uganda was reported by Hakiza et al (2009). Drastic yield reductions and hence income reductions, force smallholder coffee farmers to diversify further or even leave agriculture altogether, sometimes after generations of coffee cultivation.…”

“…One agriculturist reported that he had observed the disease first in the 1970s on a large abandoned plantation on the road to Aketi, which confirmed other reports that the disease had re-emerged as a serious problem in this part of Africa at that time-just when most scientific authorities considered it as a minor problem (Flood 1996). Surveys were also undertaken in adjacent Uganda in the mid 1990s and these confirmed the presence of the pathogen there (Hakiza et al 2009). …”

“…Another example of re-emergence is Coffee Wilt Disease (CWD) in Africa which is causing significant yield losses e.g. 77 % loss of robusta yields in Uganda (Hakiza et al 2009). CWD is of particular significance because unlike many other coffee pests, it kills the trees and the farmer, who is often unable to replace his crop easily, faces major income shortfalls.…”

Up to 80 % of global commodity production comes from smallholdings of less than 0.5 ha. Yet commodity crops may be a substantial proportion of a country's exports, and feed into global supply networks. Pest risks thus have consequences at local, national and global levels. We consider three categories of risk in global commodity networks: introduction of pests to new areas, upsurges of established pests and the risks arising from management efforts. In each category we provide case studies and examples, and consider policy options. Increased travel, trade and transport increase the risks of introduction. Commodity specific biosecurity plans are required for preventing introductions, including analysis of the specific risks (pest pathways) and preparation of emergency responses. Regional and international cooperation is essential. Upsurges can be caused by crop management, evolution of new strains, and environment change. National systems must be responsive to detect problems and address them quickly. Capacity building for surveillance and diagnostics, and the development and dissemination of integrated pest management methods are needed. Investment in research and extension for the agricultural sector is vital. Risks linked with management efforts, specifically, the risk from agrochemicals are considered. Concerns in developed countries over food safety and environmental damage can place constraints on pest management. Failure to comply leads to loss of markets and buyer confidence. Policies that favour lower-risk pest management methods are needed, but are often lacking.

“…F. xylarioides causes a lethal vascular wilt of coffee due to the obstruction of the xylem vessels and the disruption of water supply to the aerial organs (45,56,107). Infection leads to the death of the tree within a period that varies from a few weeks to six months (53,106,107).…”

Assessment of crop loss due to multiple diseases and pests (D&P) is a necessary step in designing sustainable crop management systems. Understanding the drivers of D&P development and yield loss helps identify leverage points for crop health management. Crop loss assessment is also necessary for the quantification of D&P regulation service to identify promising systems where ecosystem service provision is optimized. In perennial crops, assessment of crop losses due to D&P is difficult, as injuries can affect yield over years. In coffee, one of the first perennials in which crop loss trials were implemented, crop losses concurrent with injuries were found to be approximately 50% lower than lagged losses that originated following the death of productive branches due to D&P. Crop losses can be assessed by field trials and surveys, where yield reduction factors such as the number of productive branches that have died are quantified, and by modeling, where damage mechanisms for each injury are considered over several years.
