Alih fungsi lahan pertanian ke non pertanian menjadi permasalahan di kawasan pinggiran perkotaan. Alih fungsi lahan ini disebabkan land rent lahan pertanian tidak menguntungkan dibandingkan jika dibandingkan dengan lahan komersil. Jika kondisi ini terus berlanjut maka akan mengancam ketahanan pangan suatu wilayah. Penelitian ini bertujuan untuk memodelkan penentuan lahan sawah berkelanjutan berdasarkan analisis spasial dan teknik penginderaan jauh. Analisis yang digunakan meliputi analisis interpretasi citra, Geography Information System (GIS), analisis statistik, dan analisis prediksi ketersediaan lahan sawah. Penelitian ini dilakukan di Kabupaten Semarang dengan perkembangan perkotaan yang cepat. Variabel dalam menyusun model lahan sawah berkelanjutan ini terdiri dari variabel produktivitas tanaman, kepadatan dan jangkauan jaringan jalan dan sungai, kawasan lindung, serta proyeksi arah perkembangan perkotaan. Hasil analisis produktivitas tanaman menghasilkan persamaan statistik produktivitas (ton/ha) = 3,795 (NDVI) + 3,774 dan nilai r² sebesar 0,854. Terdapat selisih antara data dinas dengan data peneliti sebesar 2,8% dari luas lahan pertanian eksisiting. Selisish luas ini dikarenakan perbedaan skala peta, proses analisis, dan metode yang digunakan. Berdasarkan hasil analisis dan pembahasan maka dapat disimpulkan bahwa lahan sawah berkelanjutan ketersediannya mulai berkurang, sehingga perlu adanya ketegasan pemerintah daerah dalam menjaga ketersedian lahan sawah.

Resumo: Renda fundiária urbana é uma categoria pouco explorada pela maioria dos estudos mais recentes sobre o urbano. Porém, essa categoria oferece uma possibilidade de abordagem do urbano que permite a análise de fenômenos importantes, como a hierarquização dos usos do solo, o papel do setor imobiliário para a acumulação do capital e para a reprodução das relações de produção capitalistas, além de ser importante para o entendimento do processo de segregação sócio-espacial e fragmentação do espaço no urbano. Assim, levando-se em consideração os estudos passados e as dificuldades que ainda hoje permanecem, a questão da renda fundiária é retomada no presente artigo. Como forma de viabilização da análise da questão da renda fundiária urbana foi realizado um estudo de caso sobre uma modalidade de intervenção no urbano por parte do setor imobiliário em aliança com o mercado financeiro no município de São Paulo: os Fundos de Investimento Imobiliário e a Securitização de Recebíveis Imobiliários.  THE URBAN LAND RENT: A CATEGORY OF ANALYSIS STILL VALID Abstract: Urban land rent is a category little explored by most recent urban studies. However, this category offers a possible approach for urban space that allows the analysis of relevant phenomena, like hierarchy in land use, the role of the real estate industry for capital accumulation and for reproduction of relationships in capitalist production, besides its importance in understanding the socio-spatial segregation and fragmentation process. In this sense, taking into account earlier studies and difficulties that still remain, this article aims to analyse the problem of land rent. To make this analysis possible, we present a case study about a kind of urban intervention by real estate agents in association with the finance market in the city of São Paulo: Real Estate Investment Funds and Real Estate Bonus. Keywords: Urban Land Rent, Fragmentation, Socio-Spatial Segregation, Urban, Real Estate Financing, Reproduction of Capital.

Ecological civilization construction and rural revitalization is a strategic decision made by the central government to solve the problems of ecological protection and rural sustainable poverty alleviation. At present, the dominant agricultural operation modes in China can be roughly divided into three types: family farm mode, agricultural enterprise mode and cooperative mode. Practice has proved that different agricultural operation modes have different effects. In ecological fragile areas, how to adopt agricultural operation modes can not only promote agricultural prosperity and increase farmers' income, but also protect the ecological environment and promote the coordinated development of ecology and economy needs further analysis. Based on the current rural revitalization strategy and ecological protection background, this paper analyzes the operation mechanism of agricultural operation mode from the principal-agent and ecological land rent theory, and analyzes the development dimensions of advantageous agriculture of various modes. On the basis of rural and farmers, this paper provides references for the selection of agricultural operation mode in different regions. There are many factors that need to be considered in the choice of agricultural operation mode in ecological fragile area. In the future, each region should conduct analysis and treatment according to its own actual situation.

In this paper the urban real estate market is dealt with in the context of broad societal changes. Particular restructuring processes, such as the social and economic polarization between urban regions and the uncoupling of the spheres of production and financial investments, are leading to a rehierarchization of urban land markets and significant changes in the formation of urban land rents. The restructuring of urban land markets is demonstrated with empirical data on cities in West Germany. Against this background the author pleads for a partial reformulation of urban rent theory.
