THE GROUNDWATER RESOURCES AND ITSSUSTAINABLE DEVELOPMENTIN THE SOUTH EDGE OF TARIM BASIN

There is a potential to certain extend for groundwater development in the piedmont plain in south edge of Tarim Basin. If the surface water use keeps the scale as present, the maximum safe yield of groundwater is about 2.05 × 109m3/a that is 55.8% of the recharge. Thus the evapotranspiration discharge will reduce 60.4%, while spring water reducing 35.6%. If the surface water use rate is up to 80% and coefficient of canal water use increase to 0.55 in the future, the maximum safe yield of groundwater will reduce to 1.85 × 109m3/a with the recharge reducing to 3.1 × 109m3. However, the sustainable groundwater development is depended on the protection of the quality aspect linked with the quantity aspect. In particular, protection of the glaoier and water conservation forestry in the Kunlun Mountains and coordinating development of surface water and groundwater should be taken seriously. Besides, the legislation, administrative management and the technology construction, and ability construction are also critical important and necessary.

UTILIZATION AND SUSTAINABLE DEVELOPMENT OF ISLAND MOUNTAINS IN CHINA

The island mountain utilization is a kind of mountain utilization. Although the islands cover little area, they can be used as the base of marine development. The sustainable development of island mountains is of significance to marine development. There are more than 6500 islands (including the South China Sea Islets) in China, and most of them are continental islands which are the extension of continental mountains extent towards sea. For this reason, there are many hills but few mountains, the area of hills makes up more than two thirds of the whole land area. In order to keep ecological balance of islands, the utilization of island hills and mountains should take exploitation of forests as the main to conserve water source and water soil, and forests become an important factor in keeping ecological balance and sustainable development of islands. At the same time we should make good use of forests through setting up forest nature protecting area and forest parks and developing forest tourism.

Exploiting pattern and sustainable development of marginal lands in the Three Gorge Reservoir Areas

This paper studied the distribution and utilization status, reasonable exploitation patterns and potential productivity, and sustainable development of marginal lands in the Three Gorge Reservoir Areas. It has been pointed that problems of the soil fertility degradation, poor productivity in crop lands, natural disasters and environmental deterioration existed in all the exploited marginal lands. In order to maintain the sustainability of the marginal lands, following measure have been proposed: prohibiting cultivation in the crop lands with a slope more than 25°, restoring vegetation in the slope more than 25°, strengthening the basic agricultural construction, establishing the production base of woody feeds and oils, establishing a multi dimensional management model with reasonable structure and optimum function for forestry, agriculture and fishing.

Abkhandari (Aquifer Management): a Green Path to the Sustainable Development of Marginal Drylands

Recurrent droughts and occasional floods are the facts of life in drylands. The presence of innumerable societies in deserts is the living proof that even the extremely dry environments are livable; the secret is how to adapt to the situation. Floodwater management, the most important art of sedentarized desert dwellers, is the secret of living with deserts. Floodwater irrigation alone, or in combination with the artificial recharge of groundwater （ARG）, has sustained the Persians for millennia. The scientists at the Kowsar Floodwater Spreading and Aquifer Management Research, Training and Extension Station in the Gareh Bygone Plain have been working since January 1983 to revive this ancient art and upgrade it to the level of science. A summary of important findings is provided as follows： 1. Debris cones and coarse alluvial fans are the best places for the ARG as they provide the potential aquifer for groundwater storage. The recharged water may be used for irrigation on the lower lying, fine alluvium; 2. Flood is not a proverbial curse but a blessing in disguise, and the turbid floodwater is the best resource for the sustainable development of drylands; 3. Translocation of fine clay minerals eventually makes the vadose zone impermeable. Planting deep-rooted, drought-resistent trees and shrubs, and introducing sowbugs （Hemilepistus shirazi Schuttz） are reliable methods to increase infiltration rate and the saturated hydraulic conductivity of the ARG systems; 4. The moving sand stabilization is best achieved by spreading turbid floodwater onto them. Establishing of living windbreaks and planting of fodder trees and shrubs turn a sand menace into a verdant pasture; 5. The 10 year average of native forage yield in the ARG systems has been 445 kg·ha^-1·year^-1 as opposed to 92 kg·ha^-1.year^-1 for the control. At 4×4 m^2 spacing, Atriplex lentiformis （Torr.） Wats. can annually yield 1500 kg ha^-1 of dry matter and support 3 heads of sheep; 6. The stem- and fuel wood yield of 18 year old Eucalyptus camaldulensis Dehnh. in the ARG system have been 4,684 and 781 kg·ha^-1.year^-1, respectively. The mean annual carbon sequestration of this tree has been 2.975 tons per ha; 7.Up to 80% of the diverted floodwaters reach the unconfined aquifer. As evaporation practically wastes large volumes of water in surface reservoirs, storing water underground is logical in deserts; 8. The high evaporation rate, the large sediment load, the environmental hazards, the undesirable social costs, the long time needed for the different phases of study, and the very large price tag make dam building the most hydro-illogical choice in deserts where the ARG is practicable; 9. Each 5.5 ha of the irrigated farm provides income for a family of 7.64 member and 0.38 employment opportunities for a farm hand. On average, 4-ha of an ARG system provides one full time job for irrigation farmers. The benefit： cost ratio for this project is 22; 10. The number of wells in the area affected by the ARG activities has increased lo-fold to 130 wells, the irrigated area has increased 8-fold to 1,193 ha, and 345 job opportunities have been created in 4 villages that surround the Station.

Resource Utilization Pattern and Development in Hills——A Case for the Pindar Basin of Garhwal Himalaya, India

Agrarian system is well adapted in Himalayan eco-system. Hence, the people have adopted the traditional subsistence cereal farming and it becomes the main stay of Himalayan people. About 80 percent of the workable force is attached with agriculture and its allied practices, according to the census of 1991. Although, horticultural farming runs parallel with agriculture, its proportion in terms of land is quite less, resulted in a negligible place in the economy of the region. Human resources, mainly men are attached with national security after recruitment in Army. While, women play a vital and integrated role in maintaining the workable potential in the field of agriculture and are known as backbone of economy. An animal resource implies foremost and wider part in agricultural system and economy as well. Water resources are unutilized yet, while almost all the major rivers of our country are originated from and flowing through this region. Increasing population causes forest resources depletion. The economy of the region is rested either on 憈raditional cereal farming?or 憁oney order based?development, which could not take place due to its remoteness from the main streams of the country. The impact of modern technology with innovation in agricultural system remains impracticable due to unwillingness of people in one hand and on the other hand, adverse geographical conditions like topography, climate etc. which could not permit the uses of modern innovation in the field of agriculture. As for infra-structurally,this region is lacked behind, due to its inaccessibility. While, this region is bestowed with numerous rivers, many places for tourists and pilgrims, and huge forest resources. They might be used evenly in the development processes. The practice of tourism will help for the further development, particularly, in the wake of the newly born state, Uttaranchal. The present paper aims to evaluate the present potentiality of resources and their balanced utilization in the Pindar Basin. A precise study has been done on resource utilization, ecology and environment with keeping view in mind that more or less exploitation of resources could not influence the environment and the economy of the region.

Fluoride contamination in groundwater:A global review of the status,processes,challenges,and remedial measures

Groundwater pollution by fluoride is one of the prime concerns of the world population due to its toxicity,which results in adverse health impacts.In this paper,we review the current scenario of the fluoride contamination of groundwater in various countries across the globe and its impact on human health.During the last decade,several newly affected regions have been reported all over the world,with more than 100 countries affected by fluoride contamination in groundwater(concentration exceeding the acceptable limit of 1.5 mg/L defined by the World Health Organization).Fluoride poisoning is mainly due to the unsupervised ingestion of products for dental and oral hygiene and over-fluoridated drinking water.It is estimated that more than 200 million people from different countries are affected by fluoriderelated groundwater issues and health problems.The highest among these are from the countries in Africa(38),Asia(28),and Europe(24),followed by countries like South America(5),North America(3),and Australia(2).The source of fluoride in drinking water is primarily geogenic,together with forage,grasses and grains,tea,and anthropogenic sources.These countries affected were correlated with climatic zones and geological factors to gain insights into geospatial relations.Our analyses show that most of the fluoride pollution-prone zones are located in high-grade metamorphic terranes with granitoid or alkaline intrusions,geothermal hot springs,and volcanic regions with arid or semi-arid climatic conditions.This study also finds that children across the globe are more vulnerable than adults to fluoride contamination.The review finds that,although there are efficient fluoride removal techniques,including filters with next-generation nanomaterials,to date,there has not been a single technique developed that can claim to be a practically robust solution for fluoride removal from drinking water.Therefore,we suggest developing next-generation filters that can retain essential minerals in water and remove only harmful ones and selecting purification technologies according to need,climate,geology,and geographic location.The findings from our review would help policymakers take effective and sustainable measures for safe water supply in the affected areas.Within the framework of the Sustainable Development Goals(SDGs),particularly SDG 3(Good Health and Well-being)and SDG 6(Clean Water and Sanitation),this study emphasizes the critical role of fluoride as a key indicator.It underscores the imperative of addressing elevated fluoride levels in drinking water,particularly in African and Asian countries,to achieve the overarching objective of universal and equitable access to safe,affordable,and uncontaminated drinking water for global society by the targeted year of 2030.

Technology of Geoelectrics for Searching of Groundwater

If you drill a hole into the ground,in most places its bottom fills with water after a few days.The water appears even if no rain falls and no streams flow nearby.The water that seeps into the hole is part of the vast reservoir of subterranean ground water that saturates the Earth’s crust in a zone between a few meters and a few kilometers below the surface. Ground water is exploited by digging wells and pumping the water to the surface.It provides drinking water for more than half of the population of North America and is a major source of water for
