“…Wet periods in the Caribbean region could drastically decrease their current amount of rainfall, while dry periods will likely face increases in precipitation (except in Cordoba and the San Andres Islands, with very limited decreases). For temperature, GCM time series indicated that the largest change rates occurred in 1990s and the 2010s (Jarvis et al, 2011b). Annual precipitation variability will continue to be relevant for the whole country.…”

A way forward on adaptation to climate change in Colombian agriculture: perspectives towards 2050 The International Center for Tropical Agriculture (CIAT) believes that open access contributes to its mission of reducing hunger and poverty, and improving human nutrition in the tropics through research aimed at increasing the eco-efficiency of agriculture. CIAT is committed to creating and sharing knowledge and information openly and globally. We do this through collaborative research as well as through the open sharing of our data, tools, and publications.

“…There are various and sometimes contradictory scenarios regarding quantification of climate change's impacts on agriculture. Some authors indicate that these impacts on crop outputs remain unknown and that more research will be needed to further understand the complexity of crop responses to the climate change due to its variability and what could be the long-term average climate [44]. They differ in their approach, method, and complexity level, to make it difficult to compare among country estimates.…”

The present study aims to analyse the relationship between technical efficiency and the adverse effect of climate change manifestations among sesame farmers in Benue State, Nigeria. A combination of purposive and random sampling techniques was used to select 372 sesame producers. Data were analysed by using the Cobb-Douglas stochastic frontier production function and Spearman correlation. The stochastic production function showed that farm size, seed, fertilizer, agrochemical and family labour significantly affect sesame output. The study also showed that education, farming experience, household size, access to extension; access to credit, access to market and membership to farmer association were positively related to technical efficiency of sesame farmers. The result further showed that the average technical efficiency of sesame farmers was 0.53. The result also revealed that there is a significant negative relationship between the level of adverse effects of climate change manifestation and technical efficiency among sesame farmers in the study area. It was therefore recommended that readily available farming inputs and subsidies should be entrenched. Credit facility, extension services and good market access should be provided to farmers. Education, information and training of farmers to adapt to climate change by changing their farming practices such as bush burning, de-forestation, rain-fed agriculture and land tenure systems should be encouraged.

“…The findings are in line with similar studies in Nigeria (El-Sharkawy, 2007;Adewuyi et al, 2014) that cassava is less affected by climate variability. Study by (Jarvis et al, 2011)noted that planting of cassava could be the answer to climate variability adaptation in Africa, because cassava is "often the food crop that continues toprovide food in periods of the year when other food sources are not available" and it can also withstand drought conditions. Yam and cocoyam were found to be more susceptible to climate variability.…”

The study assesses the effects of climate variability on food crop yield of the smallholder farmers in the Lower Offin River Basin, Ghana. Spline Interpolation and Spearman rank correlation coefficient were employed to examine the spatial and seasonal distribution of climate variables. Yield anomaly index and multiple linear regression models were used to assess the effect of climate variability on food crop yield. The results showed that the higher values of seasonality and replicability indices of rainfall indicate that rainfall is concentrated within few months causing prolonged dry spells and frequent droughts during the cropping period. The regression analysis revealed that climate variability has had differential impacts on the yield of maize, rice, cassava, yam, cocoyam and plantain ranging from 18.4 % in the case of plantain to 80.0 % in the case of cocoyam. Also, cocoyam, yam and rice were much more affected by climatic conditions in contrast with maize, cassava and plantain. Therefore, there is the need to adopt drought-resistant high-yielding crop varieties to sustain high crop yield. Again, cassava and plantain have the potential to withstand climate variability which is very significant in the Lower Offin River Basin.
