Climate change has consequences and influences on agricultural productivity, especially in tropical areas such as Indonesia. Agricultural produce contributes to the level of Gross Domestic Product. Climate change is a challenge for the environment that has the most extensive impact on the economic, natural resources, and agricultural sectors, even as a concern for climate change on agricultural production. So it is needed to discuss climate change which has an impact on various sectors, especially the economic sector. This research was carried out during 2016-2018 using all provinces in Indonesia. This study uses panel data regression method, and the chosen model is the Fixed Effect Model (FEM) by displaying the effects of each region. The results of this study show that R-squared value is  0.990095 which means that 99% of independent variables collectively determine the value of GDP. Meanwhile, changes in temperature, increased rainfall, and increased air quality index partially have no effect on GDP. Only the extent of agricultural land area partially has a positive effect on GDP.

This study aims to analyze the factors forming the number of poor people in Eastern Indonesia. Panel data regression was utilized as the analysis approach, with a cross-section comprising 12 provinces in Indonesia's Eastern Region from 2010 to 2018. This study will examine the effect of total government spending on education, government spending on health, labor force participation rate, regional minimum wage, investment, and the Gini index on poverty in Eastern Indonesia. The results showed that government spending on health and regional minimum wages had a negative effect on the number of poor people in Eastern Indonesia. The number of poor people in Eastern Indonesia will decrease if the realization of government spending on health and the determination of regional minimum wages increases. The increase in the realization of government spending in the health sector indicates that regional policies on the allocation of health spending have been carried out in a proportional, efficient, and effective manner so that they are right on target. Meanwhile, government expenditure on education, investment, labor force participation rates, and the Gini index has no effect on the number of poor people in Eastern Indonesia.
