“…This results implies that 1% increase in the mean level of temperature will decrease wheat production by 0.29% and 0.38%. Our results related to temperature are consistent with the outcomes of previous research works of Pickson et al (2020) and Sossou et al (2019), who reported that temperature has negative impacts on cereal production. Further results reveal that precipitation has positive impact on wheat production in both cases.…”

This study assessed the long-run (LR) and short-run (SR) impacts of climatic and non-climatic factors, i.e., CO 2 emissions (CO 2 e), average level of temperature (ALT), average level of precipitation (ALP), area harvested of wheat and rice crops (AHW and (AHR), domestic credit (DCR), and agricultural labor (ALB) on wheat and rice production (WP and RP) in Turkey by using annual time series data ranging from 1980 to 2016 and by employing several econometric techniques. The autoregressive distributed lag-bounds (ARDL) approach and the Johansen and Juselius cointegration (JJC) test confirmed a valid long-term connection among underlying variables. The estimation results from the ARDL model reveal that climatic factors such as CO 2 emissions and temperature adversely affected wheat production in the long run as well as in the short run, whereas precipitation positively improved wheat production in both periods. Further results indicate that non-climatic factors like area harvested of wheat and domestic credit positively and significantly enhanced wheat production in the long run and short run. Similarly, CO 2 emissions also adversely affected rice production in both periods, while temperature and precipitation positively contributed towards rice production in both cases. In addition, area harvested of rice positively and significantly boosted rice production in the long run as well as in the short run, while domestic credit negatively influenced rice production in the long run but in the short run positively improved rice production. Additionally, the outcomes of the VECM Granger Causality for both rice and wheat production confirm that both climatic and non-climatic variables have a strong influence on the production of both crops. This study found that climate change has a deleterious influence on both wheat and rice production; therefore, the study suggests that temperature-resistant varieties of both crops should be developed and introduced by agricultural research institutions. In addition to this, up-to-date information is more needed related to climate change, and in the farming communities, it should be provided by agricultural extension workers.

“…This indicates that cereal crop yields show a strong correlation with temperature change, and temperature will be a significant factor for northern Togo cereal crop yields in the future [18,48]. These results are in line with those of Sossou et al [50], who stated that temperature affects cereal yield in the long and short terms in Burkina Faso. In addition, the combined effect of rainfall and temperature on the cereal crop yields in all the four locations is significant with a positive or negative sign.…”

“…It is evident from the results that there is an imperative need to adopt appropriate adaptation strategies to curb the negative effects of climate change on cereal production, as highlighted by Nyuor et al [44] in Ghana, Hounnou et al [53] who evaluated the effects of climate change on the agricultural sector in Benin, and Nana [54] who analysed the impact of climate change on cereal production in Burkina Faso. Similarly, Sossou et al [50] recommended implementing effective adaptation strategies in Burkina Faso as a conclusion to their study of the impact of climate change on cereal yield and production in that country. In this regard, many actions have been taken by the Ministries of Agriculture and the Environment, which implementations were facilitated by the fact that farmers in the study area are gradually receptive to new agricultural technologies such as climate-smart agriculture practices offered by agricultural extension officers [37].…”

This study investigates the trend in monthly and annual rainfall, minimum and maximum temperature (Tmin and Tmax) using the Mann–Kendall (MK) test and Sen’s slope (SS) method and evaluates the significance of their variability for maize, sorghum and millet yields in northern Togo employing multiple regression analysis. The historical data of Kara, Niamtougou, Mango and Dapaong weather stations from 1977 to 2012 were used. Four non-parametric methods—Alexandersson’s Standard Normal Homogeneity Test (SNHT), Buishand’s Range Test (BRT), Pettitt’s Test (PT) and Von Neumann’s Ratio Test (VNRT)—were applied to detect homogeneity in the data. For the data which were serially correlated, a modified version of the MK test (pre-whitening) was utilised. Results showed an increasing trend in the annual rainfall in all four locations. However, this trend was only significant at Dapaong (p < 0.1). There was an increasing trend in Tmax at Kara, Mango and Niamtougou, unlike Dapaong where Tmax revealed a significant decreasing trend (p < 0.01). Similarly, there was an increasing trend in Tmin at Kara, Mango and Dapaong, unlike Niamtougou where Tmin showed a non-significant decreasing trend (p > 0.05). Rainfall in Dapaong was found to have increased (7.79 mm/year) more than the other locations such as Kara (2.20 mm/year), Niamtougou (4.57 mm/year) and Mango (0.67 mm). Tmax increased by 0.13, 0.13 and 0.32 °C per decade at Kara, Niamtougou and Mango, respectively, and decreased by 0.20 per decade in Dapaong. Likewise, Tmin increased by 0.07, 0.20 and 0.02 °C per decade at Kara, Mango and Dapaong, respectively, and decreased by 0.01 °C per decade at Niamtougou. Results of multiple regression analysis revealed nonlinear yield responses to changes in rainfall and temperature. Rainfall and temperature variability affects rainfed cereal crops production, but the effects vary across crops. The temperature has a positive effect on maize yield in Kara, Niamtougou and Mango but a negative effect on sorghum in Niamtougou and millet in Dapaong, while rainfall has a negative effect on maize yield in Niamtougou and Dapaong and millet yield in Mango. In all locations, rainfall and temperature variability has a significant effect on the cereal crop yields. There is, therefore, a need to adopt some adaptation strategies for sustainable agricultural production in northern Togo.

“…Recent decade droughts, floods and heats have severely impacted the country's farmer livelihoods, especially water resources Gahi et al, (2017). These different impacts of climate risks on hydrosystems have had adverse repercussions on livelihoods of communities that depend mainly on agriculture (Barbier and Yacouba, 2009;Zorom et al, 2013;Sossou et al, 2019). Gahi et al (2015) identified vulnerability factors for agricultural water, which significantly lead to decrease of crop production and food insecurity.…”

“…Filippi et al (1990) noted a continuous decrease in groundwater recharge in the Massili in Borogo and Silmissin, both in Burkina Faso; leading to a 1 to 1.9 m drop in the water table since 1980; and an average decrease in groundwater levels of 1 to 3 m nationally (Mouhouyouddine et al, 2017). Gahi et al (2019), they noted an early drying of community wells (up to 13 m in depth); while Sossou et al (2019) highlighted the impacts of climate drivers on crop yield. According to these authors, within a short term, an increase in temperatures of 1ºC would result in a decrease in cereal yield of 72 kg per hectare; while in the long-term period, a rise in temperatures of 1ºC would result in a decrease in cereal yield of 1074 kg per hectare.…”

Burkina Faso, like other Sahelian countries, has experienced a profound change in its climatic regime,with the new context characterised by high rainfall variability with an overall downward trend and ashortening of the seasons. The future rainfall pattern anticipates a decrease in the frequency of lowrainfall (0.1 to 5 mm per day), a lengthening of the average duration of dry sequences, and an early endand late start of rainy seasons. The objective of this study was to perform an in-depth analysis of stakeholder perceptions about agricultural water (AgWater) resources sustainability, practices in the context of climate variability and change in Burkina Faso. Interviews were held with institutional actors involved in water resources decision making and initiatives (Government, Research, Non-Governmental Organisations) in the country. In addition, based on four main criteria (climate condition, type of farm and crop, type of AgWater sources, reliability of AgWater), three agricultural sites were investigated using household surveys. The results showed that organisations and farmers in Burkina Faso were aware of climate impacts and had initiated and implemented for many years, diverse options and water control mechanisms for AgWater adaptation. However, there were still gaps in strategies for adapting the water sector to climate threats. Institutional bodies had not got yet attained capacity to sustainably anticipate the effects of climate change on AgWater. There was a lack of mainstreaming hydroclimate services at farm levels, especially for the dry season crops; lack of on-farm flood control mechanisms, absence of a clear gender approach and no standardised monitoring system, Farmers also lacked anticipatory resilience strategies, particularly those who used water sources that were considered as “reliable” then. In general, most of the climate adaptation initiatives implemented lacked synergies, sustainability, and were uncertain about sound water resource management such as moving towards “no regret” and “win-win” options.
