Huangqihai Lake

The pattern of Holocene palaeoclimatic change in arid-semiarid northern China is debated. The terminal Huangqihai Lake is located at the northern margin of the modern East Asian summer monsoon and sensitive to climate change. We present here a sedimentary section from Huangqihai lake basin which comprises lacustrine and fluvial deposits and is about 8–9 m above the present lake level. Quartz optically stimulated luminescence (OSL) dating was employed to construct the chronology of the section. Based on the OSL chronology and the sedimentological and granulometric analysis, we conclude that (1) the Huangqihai Lake experienced a humid climate during the early part of the Holocene (from c. 10.2 ± 1.0 to 6.7 ± 0.7 ka) with a persistent and stable high lake level; (2) the lake level began to decline indicating aridification between 8.7 ± 0.8 ka and 6.7 ± 0.7 ka, and the climate was drier and variable after 6.7 ± 0.7 ka compared with that of before; (3) from 2.2 ± 0.2 to 0.93 ± 0.07 ka the climatic conditions were highly variable and continuously deteriorating, and the lake was turned into a playa for most of the time. In summary, the climate showed a general drying trend from the early Holocene to the late Holocene.

The Impact

Background: Child stunting is a critical global health issue. Guatemala has one of the world′s highest levels of stunting despite sustained commitment to international nutrition policy best-practices endorsed by the Scaling Up Nutrition movement (SUN). Our objective was to use Guatemala as a case study by projecting the impact of a recently published national nutrition policy, the Great Crusade, that is consistent with SUN principles. Methods: We used the Lives Saved Tool (LiST) to project the scaling-up of nutrition interventions proposed in the Great Crusade and recommended by SUN. Our outcomes were changes in stunting prevalence, number of stunting cases averted, and number of cases averted by intervention in children under five years of age from 2020–2030. We considered four scenarios: (1) intervention coverage continues based on historical trends, (2) coverage targets in the Great Crusade are achieved, (3) coverage targets in the Great Crusade are achieved with reduced fertility risk, and (4) coverage reaches an aspirational level. Results: All scenarios led to modest reductions in stunting prevalence. In 2024, stunting prevalence was estimated to change by -0.1‰ (95‰ CI 0.0‰ to -0.2‰) if historical trends continue, -1.1‰ (95‰ CI -0.8‰ to -1.5‰) in the Great Crusade scenario, and -2.2‰ (95‰ CI -1.6‰ to -3.0‰) in the aspirational scenario. In 2030, we projected a stunting prevalence of -0.4‰ (95‰ CI -0.2‰ to -0.8‰) and -3.7‰ (95‰ CI -2.8‰ to -5.1‰) in the historical trends and aspirational scenario, respectively. Complementary feeding, sanitation, and breastfeeding were the most impactful interventions across models. Conclusions: Targeted reductions in child stunting prevalence in Guatemala are unlikely to be achieved solely based on increases in intervention coverage. Our results show the limitations of current paradigms recommended by the international nutrition community. Policies and strategies are needed that address the broader structural drivers of stunting.

Study Species

This article aims to study species of herbs and their properties to develop a tourism site in Baan Nai Wang, Baanna Sub-district, Srinakarin District, Phatthalung Province, present healthy food menus for tourists that use local raw ingredients, and develop an herbal garden tourism handbook for the Songkhla Lake Basin. Data were collected through a field survey, focus group discussions involving stakeholders, and in-depth interviews with herbal experts. The study found that there are two private vegetables and herbal gardens and one public area suitable for tourism sites. Thirty-three species of herbs are used for cooking, 17 species of herbs are used for curing disease, and 5 healthy food menus use local herbs as ingredients. We found that the area should be developed as a tourism destination for visitors to learn more about herbal species and herbal properties and to cure diseases using herbs.
