Effects of Urban Land Use Change on Selected Public Utilities for Sustainable Development in Akure, Nigeria

Urban landuse change is one of the main driving forces of global environmental change. It is central to the sustainable development debate. The aim of this research is to examine the effects of urban landuse and its impact on selected public utility services in Akure with a view to improve strategies to protect these utilities for sustainable development. The research was conducted using remote sensing, Geographical information System and questionnaire to collect the required data for the purpose of fulfilling the objectives of this study. In this study of analyzing the urban landuse change, 2010 and 2018 IKONOS are used in a post classification comparison analysis to map the landuse changes and identify the conversion process in Akure. The landuse change statistics results obtained revealed that residential landuse has changed rapidly for the periods (2010-2018). The results also show increase in commercial landuses between the same periods. The results of the analysis reveal that the built-up area has been growing rapidly for the periods (2010-2018). Findings show that, housing provision (residential), business purpose (commercial) and educational (institution) are the major causes of land use change in the study areas. To reduce the effect of land use expansion in the study areas, policy measures were recommended which include regulating the growth and spread of development, regional development programs. In our opinion, the information provided by these technologies could help city planners and policy makers to attain and sustain future urban development.

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.

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.

Possible use of Lingula sp.(Phylum Brachiopoda)as a dissemination strategy to promote sustainable development in Fangchenggang mangrove,China

The economic marketability of a brachiopod,Lingula was studied at three coastal mangrove sites,specifically based on socioeconomic parameters from 10 villages that utilized Lingula along Pearl Bay,Beilun Estuary Marine Nature Reserve,China.The significantly highest density of Lingula was at Jiao Dong(48.2±35.14 individual/m^2)whereas the biomass of Lingula was highest(0.76±0.22 g/individual)at Gui Lao Bu.The shell size of the largest specimen was still less than that in other references.The socioeconomic study of the population related to Lingula involved a small group,and no relationship could be determined among the parameters of age range,education level,occupation,and financial status.The total economic value(320,927.4 Yuan)was based on the value of consumption whereas the value from sales was very low as recorded from Shan Xin over a three-month season.Analysis of the results to determine strengths,weaknesses,opportunities,and threats was undertaken to identify the potential of Lingula sp.to be promoted and supported in the market as a novel source of income for the local community who are associated with mangrove resources;and also to examine its potential as a new food source for the rapidly growing population of China.

Evaluation of Intensive Land Utilization based on Anti-planning Concept

Based on the gist of anti-planning,evaluation standards and methods of intensive land utilization were re-examined according to the inverse planning procedures.Significant role of compulsory non-development zone(similar to the traditional"non-construction land")among the planning fruits in the intensive utilization of urban land resources and relevant index weights in the evaluation system were re-weighed.In land evaluation,relevant control indexes of compulsory non-development zone were first calculated and evaluated,healthy and sustainable development coefficients of land were obtained and regarded as the core content of the whole evaluation system.

Issues and solutions of China’s generation resource utilization based on sustainable development
