1 ENHANCING FOOD SECURITY MEASUREMENT THROUGH IMPROVED CASSAVA VARIETIES, RESILIENT TO CLIMATE CHANGE IN NIGERIA USING GIS AJALA, O.N. Ph.D. Student at University of Ilorin, Nigeria and a visiting research student at University of Ghana, Legon Presented at the International Conference on Quantitative Methods for Integrated Food and Nutrition Security Measurement Lessons to be learned Brussels, Belgium, 15 th -17 th November 2017

2 OUTLINE Introduction Methodological approach Climate of the studied areas Data Acquisition Field Studies Agronomy management Practices Results and Discussion Conclusion and Recommendation

3 Food Security INTRODUCTION The world most important activities that support human life is agriculture. Food insecurity can be reduce by sustainable agricultural practices as well as agricultural system adapted to a particular area Troech and Donahue (2003). Nigeria has a great history on agriculture as the country main economy before the oil boom in the 1970s (CBN, 2000).

4 Introduction cont Edeoghon et al., (2008) stated Nigeria economy cannot be accomplished outside agriculture. Sustainable agriculture has benefits of meeting human needs for food Adoption of improved cassava varieties can contribute to agricultural growth by reducing poverty, malnutrition and improve food security. Problem Agricultural productivity is highly vulnerable to climate change; -To achieve sustainable development goals there is need to end hunger irrespective of ecological zone, secure food security and improve nutrition.

5 INTRODUCTION CONT Solution Spatial evaluation of soil resilient to climate change using GIS to delineate suitability farmlands suitable fo cassava production. To identifying the efficient means of distribution of improved varieties that are resistant to climate changes to farmers.

6 Materials and Methods MATERIALS AND METHODS The research was carried out in Southern Guinea Savannah Ilorin (Kwara) State, Nigeria Figure 1: Showing map Kwara State and the Study location Climate: The climate of Ilorin is humid tropical type and it is characterized by wet and dry season (Ilorin Atlas, 1981).

7 INTRODUCTION CONT Satellite data Satellite image of the study areas were generated using Landsat OLI TIRS Figure: 2 & 3 shows the extraction of agricultural land of the study areas Data Acquisition: The data used were spatial and non-spatial data

8 Materials and Methods cont Field studies: Field studies and ground truth were carried out to delineate the geomorphologic unit -and examine the reality of the interpretation and then layout the experiment for cassava cultivation Figure 4: Experimental design

9 MATERIALS AND METHODS CONT Soil sampling and analysis: Soil samples were randomly collected from two locations (Unilorin and Omupo) Agronomy Management Practices Planting Method of cassava cuttings: According to IITA (2005) Planting was done at 20-25cm long per cutting per stand at 1m x 0.75m spacing for sole cropping Figure : 5 shows the growth of 419 variety Figure: 6 shows researcher and farmers Soil Suitability assessment for cassava production/cultivation The assessment of cassava cultivation for soil suitability in the - two villages was based on the soil parameters analyzed

10 MATERIALS AND METHODS CONT Data analysis, multi criteria analysis Extraction of Agricultural Land Soil data Climatic data Ground truth, samples collection and soil data analysis Comparison weighed Multi Criteria Analysis Assign the score FIGURE 7: shows the flowchart of the methodological approach used Overlaying the weighted sum Land suitability map

11 RESULTS AND DISCUSSION CONT Figure :8 & 9 Soil parameters level for cassava suitability production in the study areas

12 RESULTS AND DISCUSSION CONT Figure 10: Land productivity map Figure 11: Land suitability map

13 RESULTS AND DISCUSSION CONT Unilorin ton/ha Omupo ton/ha 0 TMS 419 TMS 326 TMS 623 TMS 1632 Local Variety Figure 12: shows the harvested cassava varieties from the study areas Constraints to adoption of improved cassava varieties: The adoption of improved varieties in the study areas -shows that inadequate information on availability and or accessibility

14 CONCLUSION AND RECOMMENDATION the research revealed the importance of maintaining high level of Soil nutrients The improved cassava varieties could help enhance food security under good management. There should be a registered farmers group both at federal and state levels so that farmers would be carry along on when there is policy en-enactment on new technologies,

15 CONCLUSION AND RECOMMENDATION also there should be continuous monitoring and evaluation of past, present and future changes on climate, technology and agricultural development using GIS data base Moving to this level of evaluation is essential to achieving a true agrarian revolution and improvement in food security. It is very imperative to augment scientific and traditional approaches to agricultural development
