Planning and Design of Mountainous Agricultural Sightseeing Garden——a Case Study of Ruimin Agricultural Sightseeing Eco-garden

Agricultural sightseeing project is expanding with social development, yet most are confined in improvements in original gardens, with similar style or pattern. The research took Uupanshui City as an example and analyzed mountain-based ag- ricultural sightseeing in order to discuss the way to propel agriculture integration with leisure tourism, processing, establish new models for sightseeing eco-garden gardens, and benefit economically, socially and ecologically.

Systems of Agriculture Farming in the Uttranchal Himalaya, India

Agricultural practices are the main stay of the people of Uttranchal. Out of the total population, more than 75% people are engaged either with the main occupation of agriculture or its allied practices, dominated by traditional subsistence cereal farming. Among them, the main crops are rice, wheat, millet, barley, all types of pulses, all types of oilseeds and almost all types of fruits. The crops, vegetables and fruits of all varieties are grown in the different climatic zones such as tropical, temperate, and cold because, the region is characterized by the different altitudinal zones elevated from 200 m to more than 8000m. As a result, different climates are found from hot tropical to sub temperate and chilly cold. Pulses varieties are grown extensively. Among vegetables, potato, onion, carrot, all types of green leaf vegetables, brinzal, pumpkin, ladyfinger, pea, gram, radish, ginger, garlic, etc, are grown widely. All fruit varieties are grown in the different altitudinal zones. The main fruits are orange, malta (a big size of orange), elephant citrus, lemon and all other types of citrus, apple, stone fruits including peach and pears, many kinds of nuts, and the fruits which are grown in the low lying areas. In spite of feasible climatic conditions, agricultural dominant society, and availability of all types of crops, the production and productivity of these crops are very low, even they are unable to meet the grain-need of the people in Uttaranchal. Agricultural crops are grown almost in all the altitudinal zones — from the low-lying areas, which are called ‘Gangarh’, to the highly elevated region, where the legendary term is given as ‘Danda’. The growing seasons vary according to the heights. The present paper aims to discuss the agricultural practices including cropping season, cropping pattern, land use, production of crops and ecological aspect of agricultural system in this Himalayan state and suggest some measures for developing farming system, which could lead the sustainability, in terms of meeting the food grain needs of the people on the one hand and restoring the ecological balance on the other.

Assessment of Coffea Shade Value through Comparison of Mountainous Area with Farm Land Coverage,in Arsi Gololcha District,Oromia,Ethiopia

Coffea cultivation with shade tree is used for improving soil health,increasing coffea production,sustaining agro ecology.The study was attended in two kebele,on 36 farmers’fields,at Gololcha district of East Arsi zone.The study was intended to assess the influence of coffea shade trees on farm lands versus mountainous area.Household interviews were used to get imperative separately,i.e.from old farmers,middle age farmers and young farmers.Significant difference value was observed between farm land and mountainous area coverage.Based on this respondents’idea,before 25-30 years;the‘condition of tree coverage at mountainous’area in Arsi Gololcha district was‘medium condition’but not normal that means as deforestation of mountainous area have been starting before 30 years’time;while the condition of tree coverage at farmland area also has been starting before 30 years’time.The third respondents’idea was interpreted with the real situation of the district,that it gave us a constructive inspiration on the role of coffea shade tree to enable the farm land to be taken as regular natural forest.The existing coffea shade trees are Cordia africana followed by Erythrina abyssinica and Acacia senegal.Farmers accounted 95%of coffea shade users and 4.6%without shade users.The respondents said that even if the rainfall intensity is increasing at farmland rather than mountainous area occasionally due to shade tree effect.On the contrary side,mountainous area exposed to deforestation since the farmers have been shifting to hilly side for their livelihood dependency.

Protection of Zero-Sequence Power Variation in Mountain Wind Farm Collector Lines Based on Multi-Mode Grounding

The arc-suppression coil(ASC)in parallel low resistance(LR)multi-mode grounding is adopted in the mountain wind farm to cope with the phenomenon that is misoperation or refusal of zero-sequence protection in LR grounding wind farm.If the fault disappears before LR is put into the system,it is judged as an instantaneous fault;while the fault does not disappear after LR is put into the system,it is judged as a permanent fault;the single-phase grounding fault(SLG)protection criterion based on zerosequence power variation is proposed to identify the instantaneous-permanent fault.Firstly,the distribution characteristic of zero-sequence voltage(ZSV)and zero-sequence current(ZSC)are analyzed after SLGfault occurs in multi-mode grounding.Then,according to the characteristics that zero-sequence power variation of non-fault collector line is small,while the zero-sequence power variation of fault collector line can reflect the active power component of fault resistance,the protection criterion based on zero-sequence power variation is constructed.The theoretical analysis and simulation results show that the protection criterion can distinguish the property of fault only by using the single terminal information,which has high reliability.
