Humanitarian relief is the provision of lifesaving assistance to those in the need, including victims of conflicts and natural disasters. This has led to less productivity and less engagement of the affected community, negatively affecting their social and economic status. This study examines the effect of partnership on the localization of humanitarian aid of NGO in Wajir County. The findings will provide a critical examination of the relationship between creating partnerships and localization of humanitarian aid. The descriptive research design was adopted with a target population are 280 NGO operating in Wajir County and a sample of 85 respondents that were randomly selected from NGOs that participated in the study. The study used both secondary data and primary data were collected using questionnaires. The questionnaires were piloted to test the validity and reliability prior to actual data collection. Analysis of data was done using descriptive statistics (mean and standard deviation) and inferential statistics (Correlation and linear regression). SPSS version 24.0 was used to aid analysis. Out of the 85- questionnaire administered, 78 were filled and submitted back for analysis. The aggregate mean of 3.76 and standard deviation of 0.871 was recorded on indicators used to measure the partnerships. High values of mean indicated high weights respondents gave in relation to indicators and low values of standard deviation indicated same opinion by respondents in relation to the statements given. This was the same scenario on descriptive statistics of localization of the Humanitarian aid which had aggregate mean of 3.97 and standard deviation of 0.295. Pearsons correlation between partnership and localization of the Humanitarian aid was (r=0.717; p= 0.000) indicating high positive correlation. The model summary indctaed that 51.4% of variation in localization of the Humanitarian aid can be explained by the partnerships created. ANOVA results gave a F-value of 20.617; p=0.000, indicating that partnerships is a significant predictor of localization of the Humanitarian aid. The regression coefficient of 0.459 indicated that a unit increase in partnerships would increase localization of the Humanitarian aid by 0.459 and this was statistically significant. The study conclude that partnerships determine localization of humanitarian aid of NGO in Wajir County.
