Abstract ▼ AI-Helper

This study extracted deforestation area and degraded forestland area, which are potential REDD+ (Reducing Emissions from Deforestation and Forest Degradation) project candidate areas in Paraguay using Land Cover Map (LCM) and Tree Cover Map (TCM). The REDD+ project objectives scenarios were set three stages: 'afforestation and economic efficiency scenario', 'local capacity reinforcement scenario', and 'Infrastructure-oriented scenario'. And then, we evaluated the project unit suitable area of the REDD+ project. All scenarios selected the evaluation factors for each scenario in addition to the area ratio factors for deforestation area and degraded forestland area and weighted values were extracted by assigning category scores. As a result of the three scenarios comparison analysis, Concepcion state score was the highest. Within Concepcion state, the Belon district had the highest score, making it appropriate as a project unit REDD+ project candidate area in Paraguay, while the San Carlos district had the lowest score. This study can be used as basic data for selecting REDD+ project candidate area in Paraguay, and it is expected to contribute sufficiently to REDD+ project if additional data or information of social, cultural and economic sectors are secured.

문제 정의

The purpose of this study was to assess the suitability of REDD+ project candidate areas for each scenario in Paraguay using geospatial information and statistical data and to select target sites according to the REDD+ project objectives.
The United Nations Conference on Environment and Development (UNCED) held in Rio de Janeiro, Brazil in 1992, the United Nations Framework Convention on Climate Change (UNFCCC) was adopted to promote sustainable development. This treaty aimed to stabilize the greenhouse gas (GHG) concentrations in the atmosphere (Ministry of Environment 2016). There was, however, no system to guarantee the implementation of measures to reduce GHG emissions.

제안 방법

Afterwards, a scenario analysis was conducted in the Admin Level 2 units within Concepcion, which were found to be suitable REDD+ project candidate areas.
Based on these results, the Admin Level 1 unit were analyzed. The evaluation determined that Concepcion is suitable as an REDD+ candidate area in Paraguay, and a detailed analysis was conducted for the Admin Level 2 units within Concepcion. The Belon district received high scores of 77.
The evaluation factors were constructed using geospatial information and statistical data. The data from the statistical office of Paraguay (DGEEC) were used for the population, poor population, and Gini coefficient of each state in Paraguay, and the 2012 geospatial information of DGEEC was used for the road network and water system network.

이론/모형

The scenarios were the “afforestation and economic efficiency scenario” “local capacity reinforcement scenario” and “infrastructure-oriented scenario”. The evaluation factors to be considered in each scenario were selected and weighted using the ranking method. Based on the derived results, the sites in Paraguay suitable for each scenario were evaluated (Fig.

성능/효과

Assignment of category scores for each factor: The range of values for each evaluation factor were divided into five groups, as shown in Table 2, and category scores were assigned to each group. Because the necessity of REDD+ projects increases alongside the increase in the area of deforestation areas and degraded forestlands, 100 points were assigned to the areas with the highest scores for factors such as the population, the poor population ratio, Gini coefficient, and annual precipitation, and points were proportionately allocated to other areas. The supply and demand of the workforce became more significant as the population increased, and areas where the proportion of the poor population and the Gini coefficient were high met the objectives of the local capacity reinforcement projects.
After the extracting deforestation areas (2005-2015) and degraded forestlands (2005-2015), the area ratio of the factors was calculated for each state. It was found that Boqueron, Alto Paraguay, and Presidente Hayes in western Paraguay exhibited high values of 82.4%, 70.9%, and 51.2%, respectively, while eastern Paraguay showed a low average value of approximately 28%. In particular, Asuncion with the largest population exhibited the lowest area ratio (3.

Research was limited by the factors that could not be considered due to lack of sociocultural and economic data. The results of this study, however, are expected to be used as basic data for REDD+ projects in Paraguay.
Therefore, this study considered Paraguay, a country expected secure carbon credits through overseas afforestation, as a candidate area for REDD+ projects based on the selection criteria suitable for the objectives of these projects. Site assessment in the determined scenarios was performed based on the four project objectives classified in the guidelines on the implementation of the Indonesia REDD+ project.
