“…About 26.3% (n = 36) emphasized on mitigation only [47,48,62], while 21.9% (n = 30) on both productivity and adaptation issues [42,63,64]. A relatively limited number of the publications combined productivity and mitigation pillars (6.6%, n = 9) [49,65,66]; adaptation and mitigation (2.9%, n = 4) [67][68][69][70]; and in adaptation alone (6.6%, n = 9) [71][72][73].…”

Institutional Perspectives of Climate-Smart Agriculture: A Systematic Literature Review

Climate-smart agriculture (CSA) is increasingly seen as a promising approach to feed the growing world population under climate change. The review explored how institutional perspectives are reflected in the CSA literature. In total, 137 publications were analyzed using institutional analysis framework, of which 55.5% make specific reference to institutional dimensions. While the CSA concept encompasses three pillars (productivity, adaptation, and mitigation), the literature has hardly addressed them in an integrated way. The development status of study sites also seems to influence which pillars are promoted. Mitigation was predominantly addressed in high-income countries, while productivity and adaptation were priorities for middle and low-income countries. Interest in institutional aspects has been gradual in the CSA literature. It has largely focused on knowledge infrastructure, market structure, and hard institutional aspects. There has been less attention to understand whether investments in physical infrastructure and actors' interaction, or how historical, political, and social context may influence the uptake of CSA options. Rethinking the approach to promoting CSA technologies by integrating technology packages and institutional enabling factors can provide potential opportunities for effective scaling of CSA options.

“…Higher (or very low) temperatures and low humidity level are less likely to support the growth and development of most of the pests and insects. Bendito and Twomlow (2015) have recently started the debate on strategies to save the existing and future post-harvest facilities from impacts related to floods, droughts, high temperatures and other weather-related disasters due to climate change and from earthquakes. There is also a need to understand how farmers residing to different climatic conditions respond in terms of storage and preservation technologies is important.…”

This paper focuses on improved storage and preservation technologies as an adaptation strategy in response to climate change. We also study the trade-off between improved cereal storage technologies and the preservation techniques among rural households in Tanzania. We find that climate variables significantly influence farmers' choice of improved storage technologies and preserving decisions. Using a bivariate probit model, we find that modern storage technologies and preservation measures are substitutes. Farmers can significantly reduce annual costs associated with preservation by adopting (usually long lasting) modern storage facilities.

“…The rise in grain moisture content in Super guard dust and untreated control in Harare may have been linked to high infestations of storage insects. Temperature and relative humidity (local environmental conditions) play a critical role in influencing grain moisture content, pest development (Musolin and Saulich, 2012;Bendito and Twomlow, 2015), and influencing pesticide persistence and success (Katagi, 2004;Ismail et al, 2012;Bell, 2014). If the pesticides degrade beyond potent levels, re-infestation will occur (Afridi et al, 2001).…”

Blanket application rates for synthetic grain protectants across agro-climatic zones: Do they work? Evidence from field efficacy trials using sorghum grain

et al. 2018

Many smallholder farmers in sub-Saharan Africa rely on synthetic pesticides for protecting stored-grain. Recommendations on use of these grain protectants are typically based on "blanket" application rates which are fixed rates that are not varied according to grain type, pest range or agro-climatic regions. There are numerous anecdotal reports of storage pesticide failure or reduced efficacy from farmers. Might rising global temperatures be a contributory factor? Smallholder farmers are responding by over-applying pesticides, increasing the application frequency or switching to non-recommended pesticides; leading to a pesticide treadmill. Trials to determine the efficacy and persistence of five commercially-available synthetic pesticides applied at manufacturer's recommended rates on stored sorghum grain under contrasting climatic conditions were conducted in Mbire (mean temperatures of 32-42 o C and 30-50 % rh) and Harare (18-32 o C; 42-75 % rh) districts in Zimbabwe. Grain samples were collected at 8-*Manuscript Click here to view linked References week intervals throughout a 10 month period in the 2014/15 and 2015/16 storage seasons. The samples were analyzed for insect grain damage, weight loss, total number of storage insects by species) and grain moisture content. Results showed significant differences in the performance of treatments (p < 0.001). Grain damage was consistently higher in Harare than in Mbire. Tribolium castaneum was the dominant pest in Mbire, while Sitotroga cerealella and Sitophilus oryzae were dominant in Harare. Tribolium castaneum populations were high in the Shumba Super dust ® (fenitrothion 1% + deltamethrin 0.13%) treatment in Mbire, while S. cerealella was dominant in Super guard ® (pirimiphos-methyl 1.6% + permethrin 0.4%) and Actellic Gold dust ® (pirimiphos-methyl 1.6% + thiamethoxam 0.36%) treated grain in Harare. Grain moisture content varied with ambient conditions, and was high in treatments with high insect pest levels. The results show that differences in climatic conditions influence insect pest species dynamics and response to pesticide treatments. Storage pesticides are not equally effective across different climatic conditions; thus more context-specific application recommendations are required.
