Abstract

Climate change is one of the biggest challenges facing the world today. This phenomenon has significantly impacted the degradation of natural resources, posing a serious threat to the agricultural and fisheries sectors, especially in developing countries. Climate change affects the structure of land and water and directly impacts the potential sectors in a region. The primary objective of this study is to quantitatively analyze the impact of climate change on resource degradation across the leading commodity sectors, namely agriculture, plantations, and fisheries in the Southern Sumatra region. This research adopts a mixed-methods approach, integrating multiple regression analysis using regional data from 2015 to 2022 with a Sharing Group Discussion (SGD) component to ensure contextual validation and deeper insights. The findings indicate that six meteorological factors (wind speed, rainfall, solar radiation, air temperature, air pressure, and humidity) significantly influenced degradation within these three crucial sectors. Ultimately, this study offers a forecasting overview of the climate impacts on specific commodity sectors, providing a crucial basis for stakeholders to formulate anticipatory policies, plan appropriate technological adaptation, and implement more effective resource management strategies to address the challenges of climate change.

Abstract

Connectivity infrastructure is one of the crucial aspects in the development of a region. The Indonesian government has allocated a significant budget for connectivity infrastructure spending. The effectiveness of infrastructure spending reflects how much the connectivity infrastructure indicators have been achieved. The increase in connectivity infrastructure spending must be directly proportional to the rise in the quality and quantity of connectivity infrastructure. This study aims to analyze the correlation between connectivity infrastructure spending and the achievement of its indicators, especially in the Southern Sumatra region. The analysis method used is the Pearson Correlation analysis method, an approach to analyzing growth and the effectiveness of connectivity infrastructure spending. The results show that infrastructure spending and the achievement of its indicators have a relatively weak and negative correlation for roads and bridges. This study provides implications that the Southern Sumatra Region still needs improvement and evaluation between the distribution of government spending and program implementation for better regional development effectiveness.
