  1. Economic Impacts of Chronic Kidney Disease (CKD) on Paddy Farming Community in Anuradhapura District of Sri Lanka By: Amaranayake, P.W.P. Department of Agricultural Systems Faculty of Agriculture Rajarata University of Sri Lanka

  2. Introduction • Chronic Kidney Disease (CKD) Condition in which the kidney function gradually declines until the kidneys are unable to filter waste from the body and maintain the proper balance of water and chemicals. • 200 in every one million of the population in Sri Lanka, are afflicted with renal failure. • Proportion is much higher in North Central Province - emerging health scourge • Around 80% of cases from Anuradhapura district . • 1st leading cause of death in Anuradhapura district • Worrying increase of CKD in certain DS divisions

  7. Background of the Research problem • Past researches on CKD mainly addressed on CKD of unknown etiology in Sri Lanka. • Instances of economic Impact estimations on other Chronic diseases except CKD are available (In other countries).

  8. Problem Statement • CKD is a life threatening disease in Sri Lanka especially in North Central Province. • Any of Economic impact analysis of CKD has not been conducted in Sri Lanka yet. • Lack of scientific identification and estimation of economic burden of CKD and joint action for CKD prevention, from a perspective of agriculture and health are occurred.

  9. Presence of end stage CKD Negative impact on Economic performances of paddy farming community Family and exchange labor Farming systems Operated paddy extent Labor migration Yield and Income Hypothesis Statement

  10. Objectives General objective: To determine the economic impact of End stage CKD on paddy farming community in Anuradhapura district of Sri Lanka. Specific objectives : • To analyze thecosts and returnsof paddy farming for affected and non-affected samples. • To compare thedifferences of costs and returnsof paddy farming between two samples. • To analyzethe additional burden of hired labor due to CKD on affected paddy farmers.

  11. Methodology Study area • Padaviya and Medawachchiya (high prevalence of CKD) DS divisions in Anuradhapura district. Data and sampling • Cross sectional type data • Pre tested structured questionnaire survey • Random sampling • Affected sample size =100 • Non affected sample =100

  12. Analytical methods 01) Analysis of costs & returns:- (objective 01 & 02) • Main costs and returns of two samples were calculated for an hectare of cultivation. • The difference between estimated mean values of main cost and returns of two samples were statistically compared for any significant difference. 02) Analysis of additional burden of hired labor :-(objective 03) • Additional cost of hired labor for the affected group was compared to that of the non affected ones.

  13. Results and discussion 01)Analysis of costs and returns for paddy Farming

  14. 02) Comparison of differences of cost and return values between two samples

  15. 03) Analysis of Additional burden of Hired labor due to CKD on affected paddy farmers • The additional hired labor requirement for a affected farmer: 11. 01 man days/ha • Average additional burden of hired labor : Rs 3734.40 Rs/ha/Farmer • Additional burden of hired labor borne by the farmers who are affected by CKD : Rs2.84 millions per season (Rs 5.69 millions per year ) • Under estimation of severity of real burden due to limitations in the study

  16. Family, Exchange and hired labor inputs Comparison of Family and Exchange and hired labor inputs between affected and non-affected samples

  17. Operated and non operated paddy extents Comparison of Operated & non operated paddy extents between affected and non-affected samples

  18. Labor migration after CKD Comparison of Labor migration after CKD between affected and non-affected samples

  19. Comparison of yield and prices between affected and non-affected samples • Yield Performances

  20. Comparison of Farming systems between non-affected and affected samples • Farming systems

  21. Conclusions • Use of family and exchange labor was significantly less in the affected sample. • Net income excluding imputed cost of labor of affected farmers was significantly less than the non-affected farmers. • Value of additional burden of hired labor borne by the CKD affected farmers in selected DS divisions is Rs 2.84 millions/season. • Presence of end stage CKD is negative impacts on the economic performance of the paddy farming community in the Anuradhapura district.

  22. Recommendations • Implications to prevent CKD • Entire population in the identified risky areas should undergo screening for a basic renal investigations. • Community based awareness programs on CKD risk factors should be launched. • Implication to increase the income from paddy • Work out a system for encouraging use of exchange labor. 3. Implications to develop the household income and status • Well organized counseling programs should be in place to advice and help affected farmers and other family members • Home gardening should be promoted with the support of all family members and experiences of affected farmers.

  23. Limitations of the Research study • Unavailability of well organized up dated computerized or at least a manual database. • Difficulties in obtaining accurate facts in detail from end stage kidney disease patients since they do not keep records and suffering from illness. • Time & Budgetary constraints. • Conventional objections, arguments and rules and regulations of some authorized people in related institutes as well as in farming community. • Difficulties in contacting resource persons

  24. Suggestions for further research • Further Research work to confirm the suspected causal factors, habits and behaviors for CKD (Unknown aetiology). • Further analysis of role of hired, family and exchange labor inputs under the categories of men, women and children. • Further research works to verify the link between occupation and CKD prevalence (occupational relationships). • Research works which focus on the socio economic impact of CKD on farmers’ household income by considering all three fiscal costs.
