CHAPTER ONE
INTRODUCTION
BACKGROUND OF THE STUDY
Climate change and variability are concerns of human being. The recurrent droughts and floods threaten seriously the livelihood of billions of people who
depend on land for most of their needs. The global economy is adversely being influenced very frequently due to extreme events such as droughts and
floods, cold and heat waves, forest fires, landslips etc. The natural calamities like earthquakes, tsunamis and volcanic eruptions, though not related to
weather disasters, may change chemical composition of the atmosphere. It will, in turn, lead to weather related disasters. Increase in aerosols (atmospheric
pollutants) due to emission of greenhouse gases such as Carbon Dioxide due to burning of fossil fuels, chlorofluorocarbons (CFCs), hydrochlorofluorocarbons
(HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) etc., Ozone depletion and UV-B filtered radiation, eruption of volcanoes, the “human hand” in
deforestation in the form of forest fires and loss of wet lands are causal factors for weather extremes. The loss of forest cover, which normally intercepts
rainfall and allows it to be absorbed by the soil, causes precipitation to reach across the land eroding top soil and causes floods and droughts. Paradoxically,
lack of trees also exacerbates drought in dry years by making the soil dry more quickly. Among the greenhouse gases, CO2 is the predominant gas leading to
global warming as it traps long wave radiation and emits it back to the earth surface. The global warming is nothing but heating of surface atmosphere due to
emission of greenhouse gases, thereby increasing global atmospheric temperature over a long period of time. Such changes in surface air temperature and
consequent adverse impact on rainfall over a long period of time are known as climate change. If these parameters show year-to-year variations or cyclic trends, it is known as climate variability. Agriculture is one of the sectors most affected
by ongoing climate change. The wide range of literature on this
subject demonstrates that damages caused by climate change can be relevant to both cropping and livestock activities (IPCC, 1990; Adams et al., 1998).
Climate change will have a significant effect on the rural landscape and the equilibrium of agrarian and forest ecosystems (Walker and Steen, 1997;Bruijnzeel, 2004). In fact, climate change can affect dierent agricultural dimensions, causing losses in productivity, profitability and employment. Food security is clearly threatened by climate change (Sanchez, 2000; Siwar et al., 2013), due to the instability of crop production, and induced changes in markets, food prices and supply chain infrastructure. Moreover, because of the multiple socio-economic and bio-physical factors affecting food systems and, consequently food security, the capacity to adapt food systems to reduce their vulnerability to climate change is not uniform from a spatial point of view (Gregory et al., 2005). However, besides its primary role in producing food and fibres, agriculture performs also other functions, such as the management of
renewable natural resources, the construction and protection of landscape, the conservation of biodiversity, and the contribution to maintain socioeconomic
activities in marginal and rural areas. Climate change could aects
also this multifunctional role of agriculture (Klein et al., 2013). The ongoing eects
of climate change require the individuation of mitigation policies to reduce greenhouse gas emissions and identify appropriated adaptation strategies that aim
to contain agricultural losses both in market goods and environmental services (such as protection of biodiversity, water management, landscape preservation and so on). These strategies can easily be identified and applied if the economic effects of climate change on agriculture are assessed. However, creating models that are able to assess these effects accurately can present diiculties for several reasons. The first is data availability: while data are frequently available, they are not disaggregated on the necessary temporal and/or spatial scales. Another reason is that research about the effects of climate change involves multidisciplinary skills and competencies because analyses of the effects of climate change involve many factors such as the consideration of (Bosello and Zang, 2005):
1. Climate and other induced climate-change environmental aspects,
2. Biological and plant physiology aspects,
3. Technical and socioeconomic factors,
4. Strategies to coping with the eects
of climate change,
5. Impacts on the main economic adjustment mechanisms at the national and international level,
6. Feedback of the changed conditions on climate.
Economic and agricultural policies play an important role in such analyses, as does the geographical scale (e.g. local, regional or international) considered for
the analysis. In addition to these aspects, it is also important to consider the temporal and spatial variability of the events which in turn causes a diicult
predictability of future scenarios.
STATEMENT OF PROBLEM
The change in climate over the years has been having lots of impacts on the communities of the various nations of the world. Nigeria has been having her
share of the impacts of climate change. These impacts are felt by the farmers of Nigeria and Kebbi State in particular. Climate change is known to be having
impacts on farming practices thereby having eects
on agricultural production by the farmers. The main trust is to determine the impact of climate change on farming practices in Kebbi State, Nigeria. The question is how have farmers been coping with the impacts of the climate change all these years? When the answer to this question is found, communities will not dri
away from their locations for other places. When the farmers are allowed to move away from their various locations due to the impacts of climate change, the consequence will be communities or households dri from one place to another. This will result in hunger, poor health and poor wellbeing of the farmers’ households (Maginness & Stephens 2008 and Lal, Alavalapati & Mercer, 2011). Other results of ruralurban shidue to detrimental climate change effects
includesstresses and disturbances such as increased land use change, pollution, wild invasive species (U.S. Global change research programme (USGCRP) 2009). As these shis continue there will be high pressure on the social amenities in the newly found
home, urban area (Rumble, Tubb & Acher, 2008), hence the need for the study to investigate the effects of climate change on farming practices in Kebbi State, Nigeria.
AIMS OF THE STUDY
The major purpose of this study is to examine the eect

SIGNIFICANCE OF THE STUDY
The findings of this study will be beneficial to government, agricultural extension workers, farmers and other researchers. The study will provide information
on the perceived extent to which climate change has impacted on farming practices. The information will help government to encourage and support farmers
in production activities. The knowledge of the findings would help the government to make policies on how to check the effects of climate change on agriculture in Kebbi state and Nigeria in general. The study will provide information to agricultural extension workers on adaptation strategies, which they could teach the farmers to adapt to in such situations. One of the purposes of the study is to discover the suitable strategies for alleviating the impact of climate. The information would serve as a body of knowledge for the agricultural extension workers who teach the farmers on improved farming practices.
The findings of the study would help farmers to reduce the impact of climate change on agricultural practices. The study will suggest to the farmers suitable
adaptation options in coping with climate change effects on agriculture. An understanding of the impacts of climate change would help the framers to mount appropriate strategies to keep agricultural practices profitable to matching the varying trend in farming activities. The study could be used as a resource material on climate change and its impact on agriculture for researchers who may be interested in researching on related topics. The research is equipped
with the findings on the impacts of climate change on farming practices.
SCOPE OF THE STUDY
The study is based on the effect of climate change on farming practices in Kebbi state
