“…This correlation can be attributed to the favorable conditions that higher temperatures create for the growth and activity of soil microorganisms. As a result, these conditions stimulate the release of carbon dioxide from the soil [66]. In this research, the recorded average overall soil temperature was 31.10 5-7).…”

Sustainable management of agricultural resources is needed to meet people’s increasing demands for food, fiber and energy while maintaining the quality of the environment and protecting natural resources. With the rapid growth of agriculture and the mechanization of farming, the agricultural sector has become one of the main contributors to the increase in CO2 emissions and other greenhouse gases in the world. Therefore, the aim of this study was to determine the effect, dependence and correlations of CO2 in soil with native vegetation (presence/absence, corn yield) and climatic conditions (soil temperature and moisture) during three years of measurements under different management practices in a classical conventional agroecosystem. This research contains four different treatments: control treatment (CT), dolomite/organic fertilization (DOL/OF), mineral fertilization (MF) and black fallow (BF). During the investigated period, the average overall C-CO2 flux ranged from 7.98 kg ha−1 day−1 on bare soil to 16.26 kg ha−1 day−1 on soil treated with mineral fertilization. No statistically significant difference was observed among different fertilization treatments, except in 2013 and 2015 when comparing different fertilization treatments to bare soil. In all three years, there was a positive correlation between average C-CO2 fluxes and soil temperature. Additionally, in 2013 and 2017, there was a positive correlation between average C-CO2 fluxes and soil moisture, while a negative correlation was observed in 2015. Obtained values of crop yield ranged from 0.89 t ha−1 in the control treatment (in 2015) to 14.81 t ha−1 in the treatment with mineral fertilization (in 2017). Growing global concern about the effects of climate change calls for intensive research on the carbon cycle, and these results will contribute to the understanding of carbon transformation in different crops and soil management practices.

“…This difference was because tegalan which was closer to the settlement allowed for more intensive management than wana. Management efforts on tegalan such as tillage and weeding activities could accelerate the rate of carbon and nitrogen mineralization while decreasing soil nutrients and organic matter loss, destroy the chunks usually formed and influence the structure and function of the soil microbial community, particularly the biochemical process dominated by bacteria (Zhang et al 2022). In contrast, the community rarely carried out maintenance activities in wana, such as fertilization, weeding, watering, and replanting, due to the belief that woody plants could grow well without maintenance activities.…”

Abstract. Wardani BRP, Atmanto WD, Widiyatno, Romadini NP. 2023. Natural regeneration of Alstonia spectabilisin small-scale privately-owned forest in Gunungkidul, Yogyakarta, Indonesia. Biodiversitas 24: 3723-3734. Alstonia spectabilisis a species that serves as an indicator of the dry deciduous forest type and has the potential to be utilized commercially or to support conservation programs. The development pattern, specifically in small-scale privately-owned forest (SSPF) in Gunungkidul, still relies on natural regeneration. The differences in management between agricultural (tegalan) and forested land (wana) affect the abundance and characteristics of A. spectabilis natural regeneration. Due to its great potential to be developed in the future, information on the abundance and natural regenerationin SSPF is needed. This study was conducted by creating observation plots in tegalan and wanain Sidoharjo Village, using uniform systematic sampling with a random start method and a sampling intensity of 10%. This study aimed to determine the density and diversity of tree stand as well as the distribution pattern of A. spectabilis natural regeneration. A total of 13 nested sampling plots (0.52 ha in total size) were made to observe seedlings, saplings, pole, and tree in each study area. The number and characteristics of natural regeneration were shown to be impacted by management differences between tegalan and wana. Wana had a high canopy closure of 91%, compared to 72% for tegalan. Additionally, the greater density value of 9423 ind. ha-1in wana compared to tegalan, which had 1154 ind. ha-1 at all growth levels with a random distribution pattern, showed a stronger potential for A. spectabilis for natural regeneration. The findings indicated that wana has a greater potential for seed sources with favorable environmental conditions for the survival of A. spectabilis natural regeneration.

This paper utilizes a panel dataset encompassing 43 sub-Saharan African countries spanning from 1970 to 2019 to investigate the impact of climate change on both aggregate- and sector-specific economic growth. Via fixed effects and seemingly unrelated regression models, I show that climate change, characterized by rising temperatures and diminishing precipitation, exerts a detrimental influence on both aggregate and sectoral growth, albeit with varying degrees of severity. Such diverse effects emanate from the significant impacts of climate change on the agricultural sector, resulting in discernible alterations in output. Conversely, the industry, manufacturing, and service sectors demonstrate comparatively minor susceptibility to climate-induced change. Furthermore, the analysis highlights that the sub-Saharan African countries most vulnerable to climate change experience the greatest economic repercussions, and the most sensitive countries suffer the most.
