“…The strategies are, however, not likely to be effective without an understanding of the farmer's perceptions of climate change and access to appropriate technology, institutions, and policies [20]. For instance, climate change perceived by farmers in Nigeria is expressed in high temperature, frequent floods, erratic rainfall and droughts these posed constraints on agriculture [23]. The smallholder farmers who are the major producer of food crops are increasingly finding it difficult to cope with the dangers of climate change and variability because higher temperatures and lower rainfall reduces agricultural farmland and lower crop productivity [24].…”

Farming is a prime livelihood activity of people of Southeast (SE) Nigeria. In the age of climate change, farmers have to cope with highly variable, short and unpredicted rainfall to sustain their enterprise. This study reviews the effects of climate change on agriculture production, identifies farmer's views on the impact of climate change on crop production in the southeast, reviews the adoption of CSA in Nigeria and identifies the importance of climate information service in agriculture in Southeast Nigeria. From the review, farmers within the SE are aware of climate change and they have adopted improved innovative strategies to adapt to the negative implication associated with climate change and variability but more awareness is needed in the area of climate information services (CIS) to assist them to cope better. Therefore, this study recommends the Participatory Integrated Climate Services for Agriculture (PICSA) approach to educate farmers more on how to manage their enterprise in the face of climate change and variability.

“…Recent changes in the global climate have a considerable impact on many aspects of the natural environment and various aspects of human economy [1,2]. In addition, there is a fierce social and scientific debate concerning the origin of the climate changes that are presently being observed [3].…”

Climate change leads to global drought-induced stress and increased plant mortality. Tree species living in rapidly changing climate conditions are exposed to danger and must adapt to new climate conditions to survive. Trees respond to changes in the environment in numerous ways. Physiological modulation at the seed stage, germination strategy and further development are influenced by many different factors. We review forest abiotic threats (such as drought and heat), including biochemical responses of plants to stress, and biotic threats (pathogens and insects) related to global warming. We then discus the varied adaptations of tree species to changing climate conditions such as seed resistance to environmental stress, improved by an increase in temperature, affinity to specific fungal symbionts, a wide range of tolerance to abiotic environmental conditions in the offspring of populations occurring in continental climate, and germination strategies closely linked to the ecological niche of the species. The existing studies do not clearly indicate whether tree adaptations are shaped by epigenetics or phenology and do not define the role of phenotypic plasticity in tree development. We have created a juxtaposition of literature that is useful in identifying the factors that play key roles in these processes. We compare scientific evidence that species distribution and survival are possible due to phenotypic plasticity and thermal memory with studies that testify that trees’ phenology depends on phylogenesis, but this issue is still open. It is possible that studies in the near future will bring us closer to understanding the mechanisms through which trees adapt to stressful conditions, especially in the context of epigenetic memory in long-lived organisms, and allow us to minimize the harmful effects of climatic events by predicting tree species’ responses or by developing solutions such as assisted migration to mitigate the consequences of these phenomena.

“…The epidemiological importance of surveying ticks and TBPs in cattle from Northern Nigeria is also enhanced by the frequent movement and introduction in this region of livestock hailing from neighbouring countries like Niger, Chad and Cameroon, brought to Nigeria to be sold in more profitable local markets [38]. Furthermore, the heavy reliance on climate-sensitive economic activities, such as agriculture and livestock keeping, makes Northern Nigeria particularly vulnerable to climate change [39]. Spanning the Sudano-Sahelian ecological zone [40,41], this region is currently experiencing a combination of rising heat and declining rainfall that together are accelerating desert encroachment and marked habitat change [39,42,43].…”

BackgroundTicks and tick-borne pathogens (TBPs) represent a significant economic burden to cattle farming in sub-Saharan Africa including Nigeria. However, in the northern part of this country, where the largest livestock population reside, little is known about the contemporary diversity of ticks and TBPs. This area is particularly vulnerable to climate change, undergoing marked transformation of habitat and associated flora and fauna that is also likely to include ticks. This study aimed to document the occurrence of tick species and Apicomplexan TBPs in cattle from North-Western Nigeria.MethodsIn 2017, ticks were collected from cattle in Zamfara and Sokoto States and identified morphologically. Additionally, a subset of ticks were screened molecularly for the detection of Apicomplexan DNA.ResultsA total of 494 adult ticks were collected from 80 cattle in Zamfara and 65 cattle in Sokoto State. Nine tick species were encountered, including seven Hyalomma spp. (i.e. Hyalomma dromedarii, Hyalomma impeltatum, Hyalomma impressum, Hyalomma marginatum, Hyalomma rufipes, Hyalomma truncatum and Hyalomma turanicum), Amblyomma variegatum and Rhipicephalus (Boophilus) decoloratus. All species were present in Zamfara, whereas only five species were found in Sokoto. Hyalomma rufipes was the most prevalent tick infesting cattle in Zamfara State (76.2%), while H. dromedarii was the most prevalent in Sokoto State (43.7%), confirming the widespread transfer of this species from camels onto livestock and its adaptation to cattle in the region.Of 159 ticks screened, 2 out of 54 (3.7%) from Zamfara State and 29 out of 105 (27.6%) from Sokoto State harboured DNA of Theileria annulata, the agent of tropical theileriosis.ConclusionsThis study confirms the presence of a broad diversity of tick species in cattle from North-Western Nigeria, providing the first locality records for Zamfara State. The occurrence of H. turanicum, recorded for the first time in Nigeria, indicates a distribution of this tick beyond Northern Africa.This study provides the first report for T. annulata in Nigeria. Given its enormous burden on livestock farming in North Africa and across Asia, further investigations are needed to better understand its epidemiology, vector transmission and potential clinical significance in cattle from Northern Nigeria and neighbouring Sahelian countries.
