FIRE Journal of Science and Technology, 3(1)., (2015) 286-298 ISSN 2321-2039 Perceptions and Adaptation Measures of Crop Farmers and AgroPastoralists in the Eastern and Plateau Central Regions of Burkina Faso, West Africa. 1* 2 3 SANFO Abroulaye , SAWADOGO Issa , KULO E. Abalo and ZAMPALIGRE Nouhoun 1 2 4 SANFO Abroulaye, Ministry of Animal Husbandry, BP 490 ZINIARE, Burkina Faso; IUCN (International Union for the Conservation of Nature)/Program of Burkina Faso 3 4 Université de Lomé; Togo Institute of’ Environment and Agricultural Research (INERA), Burkina Faso ABSTRACT This paper assesses farmer’s perception of climate change and variability indicators, identifies and analyses their local knowledge about adaptation measures to climate change. For that, household interviews (100) and focus group discussions were conducted. The findings showed that Farmers have a good perception of climate change indicators, but their indigenous knowledge about the season prediction has been challenged. Climate change and variability are impacting land degradation and livestock health. Livestock diversification and mobility are agro-pastoralists’ adaptation measures whereas crop farmers are more and more interested in livestock production. Keywords: Climate Change, Indicators, Adaptation, Local communities, Burkina Faso INTODUCTION Global temperature and sea level are rising due particularly to the increase of greenhouse gases (GHGs) in the atmosphere (IPCC, 2007). Consequently, the world is facing greater weather extreme events such as heat waves, cyclones, tsunamis, droughts and floods (IPCC, 2007; Brooks, 2013, Zampaligre et al., 2013). These phenomena are affecting negatively the African farmers’ livelihoods, and particularly marginalized groups in the poorest regions, even though they are least responsible for these changes (Thornton et al,. 2006; Gbetibouo, 2009; UNDP, 2009). Agricultural sector is one of the most vulnerable to climate change impacts (Pearce, 2003; McCarthy et al., 2001; Jones and Thomton, 2009, IUCN, 2010). For instance, if nothing is done about adaptation measures, agriculture net revenues will significantly decrease in Africa (Kurukulasuriya and Mendelsohn, 2008; Namrata et al.; 2012). Burkina Faso agricultural sector has been identified by National Adaptation Program of Action (NAPA/PANA) as very vulnerable to climate change, while, 82.5% of the population lives in rural area, and 86% practice agricultural activities (SP/CONEDD/PANA, 2007). It has identified the decrease in crop yields, forage and water resources, diminution of grazing areas and livestock productivity as major threats of climate change to agricultural sector.

All rights reserved. 286 FIRE Journal of Science and Technology, 3(1)., (2015) 286-298 ISSN 2321-2039 Several empirical studies showed that negative effects of climate change on African agriculture can be signi ficantly reduced through a better knowledge about the change in climate indicators, its impacts and adaptation (Benhin, 2006; Maddison, 2006; Mano and Nhemachena, 2006; Seo and Mendelsohn, 2006; IPCC, 2007; Zampaligre et al., 2013). Some studies have investigated farmers’ perception of climate change and variability, and their adaptation practices in West Africa (Brooks 2006; Nori et al., 2008; West et al., 2008; Barbier et al., 2009; Mertz et al., 2009; Wongtschowski et al., 2009), but focused on national and regional level (Ouedraogo et al., 2010; Mertz et al., 2011) using mostly the temperature, annual rainfall, and the length of rainy season. Climate change processes are global but its impacts, vulnerability and adaptation are more local (Brown and al., 2007; Muna, 2009; Salack, 2012). In Burkina Faso, few studies have concerned crop farmers and agropastoralists/pastoralists’ perception of climate change indicators at more local level (Zampaligre et al, 2013; Kiema et al, 2013). These studies have considered the climatic indicators such as, drought and flood frequency, rainfall distribution, onset and cessation; and also their perception about these climate change impacts on their activities. Therefore, this paper attempts to assess at local scale farmers’perception of climate change indicators and impacts in Burkina Faso. MATERIALS AND METHODS Study Sites The study was carried out in two villages namely, Matiacoli and Boudry by taking into account the itineraries of transhumance routes, existence of pastoral zone or pastoral potentialities (reserves, park, forest), the frequency and magnitude (number per year) of conflicts between agro-pastoralists and crop farmers. The villages (figure1) belong to the same agro-ecologic zone (Northern Sudanian) with 600–900 mm as annual rainfall, 50–70 rainy days per season, 150 days as length of rainy season and 28 oC as mean annual temperature (PANA, 2007). Farmers cultivate sorghum, maize, rice, and cotton, while, cattle, sheep and goats are the most important livestock species kept by agro-pastoralists/pastoralists. Figure 1: Map of the study site Data collection We used the rational method of sampling to identify the two groups (agro-pastoralists and crop farmers). An agropastoralist is someone who has as main activity animal husbandry and using directly natural resources for feeding and Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications.

He must take from it his essential income (Ellis, 1988). He should have also own at least 20 heads of livestock (big or small ruminants) where he is the exclusive or partial owner because cattle herd size has been found as a determinant factor for the practice of transhumance (Zampaligre et al., 2013). Whereas a crop farmer is someone who has as main activity crop production in which he earns his main source of income. The households were at least 45 years old in order to be able to appreciate the change. Once these criteria are met, randomly and transect methods, 25 agro-pastoralists and 25 crop farmers’ households were interviewed in each villages; which amounted to 100 households in the two villages. The interviewed focused on farmers’ perception of climate change and impacts by using variables such as drought, flood, migration, pasture scarcity. A Semi-Structured Key Informant Interviews (SSKI) with 25 experts in various fields of rural development (rural development projects workers, NGOs, associations, livestock and crop extension services agents involved in natural resources management) was also done at local and regional levels. A focus groups were done including male and female household members based on their willingness to participate in the study. The tools such as “resources mapping”, “historical timeline”, “and seasonal calendar” was used (ENDA, 2013). To show the change in climate parameters, rainfall and temperature data (annually data) from nearness synoptic stations (Ouagadougou for Boudry and Fada for Matiacoali) were collected for the period 1970-2010. This period was considered because it includes the major climatic hazards such as drought and flood (CRED/EM-DA, 2013), and which are supposed to be the impacts of major changes in the climate (IPCC, 2001). Data Analysis The annual patterns of the rainfall and temperature are examined for two sites. The standardized rainfall anomalies (Lamb index) were calculated and graphically presented to evaluate inter-annual fluctuations of rainfall in the study areas over the period of observation, which is described as: SRA = (Pt − Pm)/ δ SRA = Standardized Rainfall Anomaly; Pt = annual rainfall in year t; Pm = long-term mean annual rainfall over the period of observation; δ = standard deviation of annual rainfall over the period of observation. Then, the following periods have been identified (Dereje et al., 2012): Wet period: SRA > 0.5; Normal period: -0.5 ≤ SRA ≤ +0.5; and Dry period: SRA < -0.5). STA = (Tt − Tm) STA = Standardized Temperature Anomaly= Lamb index; Tt = annual mean temperature in year t; Tm = long-term mean annual mean temperature over the period of observation Hot period: STA > 0.5; Normal period: -0.5 ≤ STA ≤ +0.5; and Cold period: STA < -0.5 The qualitative data were codified in quantitative form in the software EpiData 3.1 which was used for the data entry. We used Excel (2013) for figures drawing, while, SPSS software version 20 was used to perform both descriptive and analytical statistics (Chi-Square and Mann-Kendall Tests) with a conventional significance level of p <0.05. RESULTS Crop Farmers and Agro-Pastoralist Perception of Climate Change and Variability Indicators Unanimously both in Boudry and Matiacoali agro-pastoralists discern some changes concerning rainfall and temperature patterns (table1). Respectively 80% and 100% of them in Boudry and Matiacoali perceive a decrease of annual rainfall with a significant difference (P < 0.05) between the two sites. This decrease may result in a reduction of the number of rains per year and a shortening of rainy season. Indeed, respectively 96% (100% in Boudry and 92% in Matiacoali) and 92% discern a late onset and an early cessation (table1). That is why 88% of them think that the length of growing season is becoming shorter. Even so, respectively 46% and 77% (with significant difference at 5% between Boudry and Matiacoali) of them think Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications. All rights reserved. 288 FIRE Journal of Science and Technology, 3(1)., (2015) 286-298 ISSN 2321-2039 that rainfall intensity and floods frequency are increasing; more than 90% perceived a bad temporal distribution of this rainfall, and also an increase of drought frequency (100%), heat magnitude (94%) and duration (90%). Finally, they recognized at 88% (80% in Boudry and 96% in Matiacoali) that they are not able to predict the season because their local indicators are no longer working (from shea and grapes trees flowering and fructification). The similar results about the change in climate change indicators were confirmed by crop farmers without any significant difference (P<0.05) between Boudry and Matiacoali (table3). However, crop farmers (64%) perception of the increase of rainfall intensity is greater than the one of agro-pastoralists (46%). Change in Rainfall and Temperature Patterns The analysis of the standardized anomalies of annual rainfall in each locality for the time series 1970-2010 (figure 1) is showing an important inter-annual rainfall variation within the same locality. The climate was especially dry in these Sudan Savannah zones and precisely between 1973 -1982 and 1988-1994. These dry periods were very important and particularly in Matiacoali with 35% of moderate to severe droughts against only 15% in Boudry. The 1973-1982 droughts correspond to those that the West Africa Sahelian countries have known in 1970s and in the beginning of 1980s with huge socio-economic and environmental impacts. The analysis of rainfall data are also showing a decrease trend of rainfall as noted by farmers (figure 1). Even if these trends are not significant in Boudry and Matiacoali (P < 0.05), they confirmed the perception of farmers who have observed a decrease of rainfall. In addition, it corroborates the fact that the rainfall is decreasing rapidly in Matiacoaly than in Boudry (0.036 > 0.0286). Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications.

The temperature data analysis for the two communes is showing a spatial and temporal (inter-annual) variability of the temperature. The temperature has increased during the last forty years according to the positive coefficients of the trend (figure 2). This trend is significant in Boudry (p-value = 0.002), unlike in Matiacoali (p-value = 1). The years 1984-1994 were the cold period, while 2004-2010 were the hot one, corresponding to the perception of the majority of farmers (94%) who think that the heat is increasing. This heat is not only about the intensity because they have perceived also an increase in the length of the hot periods, therefore, a decrease in the length of the cold periods.

This availability is strongly affected by climate variability, and all (100%) the respondents have observed a decrease in soil fertility, crop yield, pasture availability and livestock productivity in Boudry as well as in Matiacoli (table 2). Climate change is impacting also livestock health (96% of respondents) and water availability (80% and 100% of respondents respectively in Boudry and Matiacoli). However, the perception of farmers about the impact of climate change on water availability is more significant (P<0.05) in Matiacoli than in Boudry. Crop farmers have observed the similar impacts of climate change (on water availability and livestock health) like agropastoralists and have highlighted its impacts on soil fertility, land availability and crop yield (table 2) To recall, 92% of respondents have identified a rainfall decrease, and what has been confirmed also by climate data analysis. This imply the reduction of pasture and water resources underlined by farmers. Otherwise, the availability of water has been perceived by 83% and 100% of respondents respectively in Boudry and Matiacoli as decreasing (table 2). Livestock health worsening has been identified by 96% of agro-pastoralists as one possible impact of climate change (table 2). They have identified the trypanosomiasis and ticks as the most important health issue. However, for them drought and flood can reduce considerably the availability and the quality of forage for livestock grazing, and increase livestock diseases. Those effects associated with heat stress can affect livestock production. This is what all (100%) the respondents have perceived by saying that climate change and variability can affect negatively livestock productivity and production. Also, all (100%) of the respondents (both in Boudry and Matiacoali) think that climate change and variability can decrease soil fertility and thereby crop yield (table 2). Livestock health data analysis shows an increase trend of trypanosomiasis and ticks cases (figure 3), though the trends are not significant in Matiacoali (p-value = 0.20) as in Boudry (p-value = 0.02). This confirms the perception of farmers who have identified a recrudescence of these parasitosis. In fact, with rainfall variability, agro-pastoralists go to trans-boundary transhumance toward Bénin, Togo and Ghana where the climate is more suitable for these pathologies. Then, they already carry the germs before getting home in July. Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications.

Farmers’ Adaptation Measures to Climate Change In order to respond to the uncertain climate, agro-pastoralists do mostly activities and species’ diversification; and also livestock mobility (transhumance and migration). While crop farmers, in addition to their activities diversification, use improved varieties and cropland expansion (table3). Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications.

Our investigations reveal that small ruminants (goat and sheep) are also presence within the households. Although, cattle remains the most important species according to the respondents, the small ruminants are becoming more and more important because they are less vulnerable to warming (requiring less water and food). For them, this is a risk-free strategy: the use of the scare natural resources by reducing the risk of livestock losses during extreme climate events. For crop farmers, sorghum, corn and millet are the most important crops cultivated. However, for economic reasons, sesame and cotton are taking an important dimension. Our investigations found that crop production occupies a very important place within cattle breeders’ production systems because 82% of them combine crop production and pastoralism (agro-pastoralism). It means that pure pastoralists are shifting to agro-pastoralism. According to cattle farmers, one of the main reasons may be due to the hard climatic condition with a scarcity of pastoral resources leading to a decrease in livestock productivity. Fulanis affirmed that in the past, milk was the basis of their food. But, with the decrease in milk production, cereals consumption has become their food habits. However, even though crop yield is decreasing, the demand is increasing with demographic growth. Consequently, cereals are inaccessible because their prices have increased, making the exchange of products difficult, that was the main mechanism by which Fulani pastoralists got cereals for their own consumption. This may be the reason why they are now into crop production because they are convinced that livestock rearing cannot be their only source of food. In addition to crop production, livestock breeders in Boudry are doing more significantly (P<0.05) fodder cropping than those in Matiacoali. Agro-pastoralists in Boudry have been settled by the government in this zone only for livestock activities and during the last years the Ministry of Animal Husbandry has encouraged them with the implementation of fodder cropping policy. Also, 82% of crop farmers have associated cattle rearing activity in their farming system (table 4). Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications. All rights reserved. 293 FIRE Journal of Science and Technology, 3(1)., (2015) 286-298 ISSN 2321-2039 Mobility One of pastoralists’ features is their ability to move according to the constraints and the opportunities offered by the climatic conditions. Among cattle rearing respondents, 86% (96% in Boudry and 76% in Matiacoali) practice transhumance. With cropland fertility reduction, 62% of crop farmers reported that they had increased their cropland over year in order to adapt to the climatic and edaphic conditions even though the use of improved variety (90% of respondents) remained one solution (table3). This cropland expansion was pointed out by pastoralists as one of the factor which amplifies their mobility. During the last thirsty years, agro-pastoralists and pastoralists practice transboundary transhumance toward Benin, Togo and Ghana, whereas, before this period they used to move to the neighbouring villages (local transhumance). Thus, at the end of February when they finish to exploit the remaining crop residues around their villages, they leave to the northern Benin, Togo (for those coming from Matiacoali), and Ghana (for those coming from Boudry) for water and green pasture. They will come back in July with the onset of rainfall that allow the growth of herbaceous. According to breeders, the present scarcity of water and pasturelands explain their early departure for transhumance and their belated coming back is due also to the delay onset of the rainy season. This has been aggravated by the environmental policy of reserves creation during these last years. The changes that agro-pastoralists have identify in their mobility patterns are the increase of distances to find available resources and also the duration of transhumance period. The actors of transhumance are mostly Fulani (96%), but in Matiacoali some Gourmantche (4%) do also this practice toward Benin and Togo. Table 4 is well illustrating what has been said about the transformation of livestock and farming system over time. Farmers are shifting from pure crop and livestock system to agro-pastoralism and crop-livestock system.

Also, drought and flooding are becoming more and more frequent and severe over the last thirty years. Finally their indigenous knowledge (from shea and grapes flowering and fructification) for the season prediction have been disrupted. The similar results were found by many authors (Lema and Majule, 2009, Wongtschowski et Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications. All rights reserved. 294 FIRE Journal of Science and Technology, 3(1)., (2015) 286-298 ISSN 2321-2039 al., 2009; Zampaligré et al., 2013. Farmers’ perception has been confirmed by the climatic data analysis that showed a decrease trend of rainfall with a frequency of moderate to severe drought, and an increase trend of temperature. In addition the rainfall seams decrease significantly in Matiacoali than in Boudry The NAPA of Burkina-Faso (2007) has also found a global decrease in rainfall and an increase in temperature throughout the country between 1961-2000. However, Zampaligré et al., (2013) have found an increase in annual rainfall in the Southern Sudanian region (Nobere) using 1998-2008 data series. Even though the data series (20 years) are not enough, it confirms the results of IPCC (2007) that found a global decrease in rainfall and an increase in temperature with a nuance that some areas will have more rainfall, while some areas will be in deficit. Our study areas are in this second scenario. However, because local populations’ indigenous knowledge of the season prediction has been disrupted, this may affect their local mitigation and adaptation strategies (Nyong et al., 2007). According to agro-pastoralists, climate change and variability impacts pasture, water resource, livestock health and yield which have been confirmed by crop farmers. In fact, water resource, crop and pasture productivity are highly correlated with climatic conditions such as rainfall and temperature. Rainfall decrease entails a reduction of pasture and crop production (Lema and Majule, 2009; IUCN, 2010). An increase in the temperature stimulates plants evapotranspiration leading to drought (IPCC, 2007). Also, Nardone et al., (2010) found that climate change may increase the prevalence of parasites and diseases that affect livestock because in areas with increased rainfall, moisture-reliant pathogens could thrive. Farmers’ perception about climate change impacts on the pastoral resources have been found also by Wongtschowski et al., (2009); and Zampaligre et al., (2013). They arrived at the conclusion that climate change is impacting pasture availability, the soil fertility, the desertification, and the pastures specific composition (eg: biodiversity). To adapt to the impacts of climate change and variability agro-pastoralists diversify their activity, diversify their livestock species, and practice transhumance. The small ruminants play an important role in their livestock system by allowing them to meet their immediate social and economic needs (Malonine, 2006). Diversification through crop production gives them both cereals for their own consumption and crop residues for livestock feeding. For the mobility, they are doing transhumance that currently defers by a precious departures, the late returns and the distances covered that is more and longer. These types of diversification and the mutation in transhumance practices as risk-adverse methods are mentioned by many authors in the context of climate change and variability (Nori et al., 2008). Crop farmers, in addition to diversification practices, they do also shift cultivation, expand their cropland, and use improved varieties. Farmers’ adaptation practices such as transhumance, expansion of cropland or shifting cultivation as well as migration are in general more spontaneous and cannot build deeply their resilience to the impacts of climate change (OECD/SWAC, 2008) even though transhumance is a strategy adapted to dry lands with scarce resources and high climate variability (Breusers, 2001; Brook, 2006; Nori, 2007; Nori et al., 2008; Zampaligre et al., 2013). Then, the frequency and severity of extreme climate events (floods, droughts) and the rainfall variability are threatening farmers’ adaptive capacity (Kandji et al., 2006). As they have low adaptive capacity to climate change impacts for their resilience building, farmers become more and more vulnerable. CONCLUSION Farmers’ perception of climate change and variability indicators, and climate data analysis show a decrease in rainfall and an increase of temperatures with a shortening of rainy season in our two districts of study. Climate change and variation have impacted natural resources availability such as pasture, water, cropland, livestock routes, and worsening livestock health and crop yield. Climate change is a risk to human security by its potentially negative effects on people’s well-being Firepubs/fjst/3/1/2015/286-298,www.firepubs.com ©2015FIRE Publications.

Climate change adaptation has to be integrated in disaster risk reduction strategies and should be mainstreamed into land plans strategies at national, local and sectorial levels. In addition, climate foresight and scenarios have to be integrated into planning for livestock development for a better building of community resilience.
