Department of Agricultural Economics, Federal University Dustin-ma, Katsina State Corresponding Authors’ Email: umarelladan72@gmail.com GSM: +2348036986704 ABSTRACT The paper assessed the impact of Climate change Adaptation and Agribusiness support Programme (CASP) on farm income and food security of maize farming households in Katsina State, Nigeria. A three-stage sampling procedure was used to collect data from 436 smallholder maize farming household using a structured questionnaire. Descriptive statistics, food security index and propensity score matching techniques were used to analyze the collected data. Result of descriptive statistics shown that average age of participating household is 48.30 years while for non-participating is 50.52 years old. The average household size of participating households are 9.22 persons while that of non-participating households are 9 persons. And also indicate that majority (89.75%) of participating household head and 94.85% for non-participating household were male with only 10.25% and 3.16% respectively are female. HFIAS result indicate that participating household in CASP programme is more food secured (1.8) then non-participating households. Propensity Score matching result shows that participation in CASP increased Net farm income and food security positively. It can therefore be recommended that participation into the programme can be used as an instrument to reduce food insecurity and increase income among rural farming households. It is also recommended that provision of adequate security by government will enhance climate change adaptation support programme participation in the future. Key words: Change, Climate, Food, Impact and Security. INTRODUCTION Maize (Zea may) constitutes the staple meal for a significant number of Nigerians and is the most critical ingredient in producing animal and aquaculture feed. Nigeria’s maize consumption occurs in the form of corn flour, confectionery, roasted corn, boiled, or prepared as porridge. Green (fresh) corn is also boiled or roasted on its cob and served as a snack. Household consumption accounts for 10-15 percent of total consumption, while the remainder goes towards food manufacturing. Over 25 percent of Nigeria’s maize production goes into animal feed, especially for poultry feed (USDA, 2021) and according to NAERLS (2020) the crop is the first most cultivated in Nigeria in terms of area (12,403,330 ha). Maize crop production and yield is threatened by changing climatic conditions and this reduction of yield as a result of climate change over the years will ultimately affect food prices and make households to spend more on food consumption Ekpa et al. (2017) reported that this will ultimately culminate in nutritional shortage and insufficient access to food. Correspondingly Xu et al. (2016), forecasted a future decrease in maize yields, with variability in maize yield being strongly driven by climate change. Shuaibu et al. (2022), also reported that climate change significantly affected the productivity of maize in Nigeria with clear implication on the welfare of households. Rural households in the northern states of Nigeria based on socioeconomic status are exposed to climate induced environmental hazards and have low adaptive capacity which resulted in low
