Research objectives: 
scientific-practical analysis of land and water reforms in Uzbekistan starting 
from 1991 independence; 
improving the econometric model that reflects the impact of land and water 
reforms (such as establishment of WUAs, optimization of cultivation area of cotton 
and wheat, optimization individual farm sieze) on agricultural productivity; 
comparative analysis of land and water reforms in Samarkand and Fergana 
provinces; 
cross-country analysis of farm cooperation in irrigated water use and crop 
production in the context of agrarian reforms (by comparing Samarkand province 
(Uzbekistan) and Turkistan province (former South Kazakhstan province in 
Kazakhstan
10
)); 
analysis of the factors affecting farmers’ cooperation decisions in water use and 
crop production; 
development of scientific and practical recommendations toward increasing the 
value of gross agricultural product; 
predicting agricultural sector performance by 2030. 
The study objects of the research are agricultural producers such as individual 
farms, dekhan and agricultural enterprises in the Samarkand province, and the 
Zarafshon Basin irrigation system. Furthermore, we conducted comparative analysis 
between Samarkand and Fergana provinces, as well as between Samarkand province 
of Uzbekistan and Turkistan province of Kazakhstan Republic.
Subject of research. Evaluation of impact of land and water reforms on 
agricultural sector performance, and factors affecting cooperation among water 
users. 
Research Methods. During our research work, the "fixed-effect" model of 
"Cobb-Douglas" production function approach and based on panel data was used to 
evaluate the impact of agrarian reform. Furthermore, we used "PROBIT" model to 
evaluate factors affecting the cooperation in water use and crop production.
