The Performance Evaluation of State Grassland Ecological Compensation and Rewards—A Case Study in Yili, Xinjiang, China

Since 2011, the State Grassland Ecological Compensation and Rewards(GECR) had implemented in 13 provinces (regions) in China. This policy controlled livestock carrying capacity on pasture and provided subsidies to pastoralists, aimed at reducing livestock number on grassland, increasing income of pastoralist households, and restoring degraded grassland ecosystem. Taking Nileke County of Xinjiang, China as a case study, this research evaluated the ecological, economic and social performance of GECR in agro-pastoral area. Using annual series data during 2006-2010 and 2011-2015, the change of grassland ecological condition, household living standard and labor population was compared between the two periods, and the influence of GECR were validated and detailed with semi-structured household interviews. The results showed that after 2011, livestock number in pastoral area decreased. In contract, the livestock in agricultural area showed large growth. Farmers’ livestock use pasture through grazing transaction, which means farmers paid herders to graze their livestock on the herder’s pasture. Widespread transactions between farmers and herders led to overgrazing on pasture and grassland degradation. GECR also had no significant contribution on improving household income and encouraging livelihood transition. The policy had no significant benefits in ecology, economy and society in case area. Based on the findings, we put forwards suggestions from three aspects: improving the design of the GECR policy, establishing performance evaluation system, strengthening the supervision and punishment of grassland overgrazing and improving local human capital quality .

Spatiotemporal Variation Characteristics of Groundwater Quality in A Semi-Arid Steppe Area in Northwest China

In this paper, the open-pit coal mine in semi-arid grassland was taken as the research object. The water samples of the open-pit coal mine and its surrounding areas were collected and the hydrochemical parameters were detected. The temporal and spatial distribution characteristics of the parameters such as pH, electrical conductivity, and dissolved oxygen in the groundwater were studied. The results showed that the groundwater in the study area was alkaline and brackish water. Climate factors might have a certain impact on the pH, conductivity, and dissolved oxygen of groundwater. The pH value of groundwater in the mining area was higher than that in the surrounding pastoral area, while the conductivity value of the mining area was between the pastoral area in the west and the Xilin river area in the east. The parameters of pH, conductivity and total dissolved solids of the four monitoring wells around the mining area showed a slow change or stable phenomenon in the vertical direction with the increase of groundwater depth. This study is of great significance to understand the characteristics of groundwater chemistry in mining areas and the rational development and utilization of groundwater resources.

Causes of different goiter rates with the same iodine deficiency among the pastoral and agricultural populations of Tibet: A geographical comparison

Background The residents of both the agricultural and pastoral areas of Tibet share the same iodine deficiency and iodine nutrition, but the rate of thyroid goiter was significantly higher in the agricultural areas than in the pastoral areas. This project sought to determine why the populations in the iodine-deficient pastoral areas show a lower rate of thyroid goiter. Methods Food frequency questionnaires (FFQs) and 24 h history recalls were adopted to investigate the dietary patterns of the residents of the agricultural and pastoral areas. Meat and milk samples were collected to measure their inorganic iodine, total iodine and thyroid hormone contents using ICP-MS, AsIII-Ce4+ catalytic spectrophotometry and the Siemens’ chemiluminescence method, respectively. The intake of protein, and the microelements, selenium and iron, was calculated according to their content in the food. Results The per capita daily intake of meat, dairy, and cereal in the pastoral areas was 116.7, 216.7, and 433.3 g, respectively, which are significantly higher than those in the agricultural areas (50.0, 72.2, and 375.0 g, respectively) (p < 0.05). The content of thyroid hormone in dried beef and milk in the pastoral areas was 62.6 and 13.5 µg/kg, respectively, which was significantly higher than those in the agricultural areas (25.1 and 4.1 µg/kg, respectively) (p < 0.05). The daily intake of thyroid hormone, protein and microelements, selenium and iron from foods by the residents of the pastoral areas were 10.5 µg, 99.6 g, 30.0 µg and 15.8 mg respectively, which was significantly higher than those in the agricultural areas (1.79 µg, 56.5 g, 23.8 µg and 13.2 mg, respectively) (p < 0.05). Conclusions The significantly high intake of the food-borne thyroid hormone by the residents of the pastoral area could be the main reason the residents in the pastoral areas show a lower rate of thyroid goiter than those in the agricultural area. Moreover, the relatively high intake of protein and trace elements, selenium and iron by residents in the pastoral area could be another important factor for reducing the goiter rates.

Taenia saginata Infection Misdiagnosed as Acute Cholecystitis in a Tibetan Patient, in China

The present study reports a rare case of Taenia saginata infection, which was initially diagnosed as acute cholecystitis in a Tibetan patient at the Qinghai-Tibetan Plateau pastoral area, China. A 45-year-old female was initially diagnosed with acute cholecystitis at a hospital in China. She had a slight fever, weight loss and constipation and complained of pain in the upper abdomen and left back areas. Increase of monocyte, eosinophil and basophil levels were shown. Taenia sp. eggs were detected in a fecal examination. An adult tapeworm approximately 146 cm in length, whitish-yellow color, was collected from the patient after treatment with traditional Chinese medicine. The adult tapeworm had a scolex and proglottids with genital pores. The scolex was rectangular shape with 4 suckers and rostellum without hooklet. The cox1 gene sequence shared 99.5-99.8% homology with that of T. saginata from other regions in China. The patient was diagnosed finally infected with T. saginata by morphological and molecular charateristics.

Co-Occurrence of Cystic and Alveolar Echinococcosis in the Liver: A Case Report

Morbidity of mixed cystic and alveolar echinococcosis (CE and AE) is exceptionally rare. Less literature retrieved from a database on the internet detailed the content, including radiography, pathology, and therapeutics data. Such a case of cooccurrence of the different Echinococcus species was diagnosed and treated at our hospital center from Nov 2019 to Feb 2020. A 30 yr old female from the pastoral area in Qinghai Province, China, was diagnosed with a case of echinococcosis and diagnosis was confirmed after image studies, immunoassaying of hydatid enzymes, life history and pathology result. The patient underwent hepatectomy along with excision of the internal capsule. Post-operative pathology was done, and it confirmed a mixed infection of both CE and AE. The patient recovered well without complications after liver-protecting and tissue repair treatment for 15 days. Knowing about infective mode and immune method of the case might be vital for research on variation for Echinococcus infection.

Camel and Small Ruminant Based Pastoralism in Ethiopia: Recent Trends and Future Prospects

In Ethiopia, camel and shoat production are common pastoralism practices in three major pastoralist regions of Afar, Somali, and Borena. This review was aimed to indicate the recent trend and future prospect of camel and small ruminant production and the possible modifiers and the pros and cons of the practices in the pastoral area of Ethiopia. The data was collected from different researches conducted each year. The data was also organized in terms of the number of camel and shoat per household each year (2010-2020) and analyzed using trend and forecasting analysis model by SPSS software. There has been an increment of camel Tropical Livestock Unit (TLU) per household from 2.78, 13 and 9 to 37, 28, and 28 between the years 2010-2020 in Borena, Afar and Somali respectively and will increase to 45, 45, and 35 by 2030, respectively. In the whole pastoralist regions, the number of camels TLU per household has increased from 2.8 to 31 between the years 2010-2020 and will increase to 50 TLU per household by 2030. Moreover, the number of goats and sheep has increased from 1.4 and 0.91 TLU per household to 2.45 and 2.46, respectively between the years 2010-2020 and the predicted model indicates that it will increase to 2 and 3.4 TLU per household by 2030. Climate change, drought and adaptation responses were the major drivers. Climate change coping and livelihood income improvements were the pros of the trend, while the reduction of cattle population and impact on the conservation of valuable indigenous cattle were the cons of the practice.
