Black soils, characterized by their thick, dark horizons enriched with organic matter, epitomize highly fertile soils. However, their fertility precipitates intense land use, engendering challenges such as soil erosion, nutrient depletion, pollution, compaction, salinization, and acidification. Notably, these soils are significant contributors to global greenhouse gas emissions, primarily due to substantial losses in soil organic carbon. Despite these challenges, black soils are pivotal for global food production. This paper delineates the implementation of digital soil mapping for the global cartography of black soils and human interference on these soils. Predominantly distributed in Eastern Europe, Central and Eastern Asia, and North and South America, black soils cover an approximate area of 725 Mha, with the Russian Federation,Kazakhstan, and China collectively have over half of this area. Agriculturally,these soils underpin significant proportions of global crop yields, producing 66% of sunflower, 30% of wheat, and 26% of potato outputs. The organic carbon content in the upper 30 cm of these soils is estimated at 56 *** management of black soils is imperative for ensuring food security and addressing climate change on a global scale.

OBJECTIVE: united nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) provides primary health care services including care for diabetes and hypertension, with limited resources under difficult circumstances in Gaza, West Bank, Jordan, Lebanon and Syria. A total of 114,911 people with diabetes were registered with UNRWA health centres in 2011. The aim of this cross-sectional observational study was to assess the quality of diabetes care in the UNRWA primary health care centres. METHOD: The study population consisted of 1600 people with diabetes attending the 32 largest UNRWA health centres and treated there for at least one year. Between April and Sept. 2012 data from medical records, including results of clinical examinations and laboratory tests performed during the last one year, current management including self-care education and evidence of diabetes complications were collected and recorded in a previously validated data collection form (DCF). Patients were interviewed and clinically examined on the day of the audit and blood collected for HbA1c testing which was done at a central lab using High-performance liquid chromatography (HPLC) method (HLC®-723G8 Tosoh Corporation, Japan). Data was transferred from paper records into a computer and analysed with Epi-info 2000. RESULTS: Type 1 diabetes was present in 4.3% and type 2 diabetes in 95.7%. Co-morbid hypertension was present in 68.5%;90.3% were either obese (64.0%) or overweight (26.3%). Clinical management of diabetes was largely in line with UNRWA’s technical instructions (TI) for diabetes. Records for 2 hour postprandial glucose (2 h PPG), serum cholesterol, serum creatinine, and urine protein analysis were available in 94.7%, 96.4%, 91.4% and 87.5%, cases, respectively. Records of annual fundoscopic eye examination were available in 47.3% cases but foot examinations were less well documented. Most patients (95.6%) were on anti-diabetic drugs—68.2% oral anti diabetic drugs (OA

Effective waste management is a major challenge for Small Island Developing States (SIDS) like Maldives due to limited land availability. Maldives exemplifies these issues as one of the most geographically dispersed countries, with a population unevenly distributed across numerous islands varying greatly in size and population density. This study provides an in-depth analysis of the unique waste management practices across different regions of Maldives in relation to its natural and socioeconomic context. Data shows Maldives has one of the highest population density and per capita waste generation among SIDS, despite its small land area and medium GDP per capita. Large disparities exist between the densely populated capital Male’ with only 5.8 km2 area generating 63% of waste and the ~194 scattered outer islands with ad hoc waste management practices. Given Male’s dense population and high calorific waste, incineration could generate up to ~30 GW/a energy and even increase Maldives’ renewable energy supply by 200%. In contrast, decentralized anaerobic digestion presents an optimal solution for outer islands to reduce waste volume while providing over 40%–100% energy supply for daily cooking in local families. This timely study delivers valuable insights into designing context-specific waste-to-energy systems and integrated waste policies tailored to Maldives’ distinct regions. The framework presented can also guide other SIDS facing similar challenges as Maldives in establishing sustainable, ecologically sound waste management strategies.
