Rice ratoon cropping,or the cultivation of tillers that have regrown from existing stem nodes of a harvested crop,is currently a hot topic in agriculture,and record-high ratoon crop yields have been achieved in china(Xu et al.,2021).Although rice ratoon cropping is most appropriate for certain agro-ecosystems with a suitable climate and cropping schedule,it is a promising strategy to simultaneously increase productivity while reducing inputs and *** ratoon cropping may thereby contribute to global food security and agro-ecosystem sustainability.

Activity data and emission factors are critical for estimating greenhouse gas emissions and devising effective climate change mitigation strategies. This study developed the activity data and emission factor in the Forestry and Other Land Use change (FOLU) subsector in Malawi. The results indicate that “forestland to cropland,” and “wetland to cropland,” were the major land use changes from the year 2000 to the year 2022. The forestland steadily declined at a rate of 13,591 ha (0.5%) per annum. Similarly, grassland declined at the rate of 1651 ha (0.5%) per annum. On the other hand, cropland, wetland, and settlements steadily increased at the rate of 8228 ha (0.14%);5257 ha (0.17%);and 1941 ha (8.1%) per annum, respectively. Furthermore, the results indicate that the “grassland to forestland” changes were higher than the “forestland to grassland” changes, suggesting that forest regrowth was occurring. On the emission factor, the results interestingly indicate that there was a significant increase in carbon sequestration in the FOLU subsector from the year 2011 to 2022. carbon sequestration increased annually by 13.66 ± 0.17 tcO2 e/ha/yr (4.6%), with an uncertainty of 2.44%. Therefore, it can be concluded that there is potential for a carbon market in Malawi.

To the Editor : Barcelona clinic Liver cancer(BcLc) Stage c hepatocellular carcinoma(Hcc) with vascular invasion has been considered unresectable. However, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. On the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced Hcc who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant Hcc in right liver lobe with inferior vena cava(IVc) invasion.
