Kalimantan Selatan dalam perberasan nasional menduduki ranking 12 dari 34 provinsi. Meski produksi beras nasional pada tahun 2019 lebih rendah dari tahun 2018, tetapi Kalsel termasuk 8 provinsi yang mengalami kenaikan dan surplus sebesar 306.621 ton atau sekitar 63,37%. Peningkatan produksi padi di Kalimantan Selatan dapat dilakukan melalui optimasi pemanfaatan lahan sawah irigasi, lahan tadah hujan, lahan kering, lahan rawa pasang surut, dan lahan rawa lebak serta lahan yang tidak digunakan. Optimasi pemanfaatan lahan untuk peningkatan produksi padi dan perbaikan ranking Kalsel dalam perberasan nasional melalui peningkatan IP di daerah yang berpotensi ditingkatkan IP-nya dengan persyaratan tertentu, peningkatan produktivitas dengan perlakuan khusus di daerah tertentu, perluasan tanam di daerah-daerah yang potensial untuk dibuka sebagai sawah baru, dan tumpangsari dengan tanaman perkebunan,  yang didukung oleh kebijakan inventarisasi kondisi eksisting lahan pertanian, optimasi dan revitalisasi infrastruktur pengelolaan air, optimasi penggunaan alsintan, pengamanan panen, konsolidasi manajemen pemanfaatan lahan, perbaikan kelembagaan pertanian dan petani, dan penyusunan tata ruang pertanian</span>.</p><p><em>Abstact. <em><span lang="IN">Problems with rice supply are faced with responsibilities, transfer of functions, and competition for land use, degradation of soil fertility and damage to agricultural infrastructure, number of farming families and policies on excavation of plants), agricultural spatial planning, population and individual consumption needs, and consumption efficiency. South Kalimantan is ranked 12th out of 34 provinces in the national rice stock. Although the national rice production in 2019 is lower than in 2018, South Kalimantan is included in 8 provinces which added and a surplus of 306,621 tons or around 63.37%. Increased rice production in South Kalimantan can be done through the optimization of the use of paddy fields, rainfed land, dry land, tidal swamp land, and swamp land and land that is not used. Improve rankings to increase production and improve South Kalimantan's ranking in national rice through increasing IPs in regions that have improved IPs with special requirements, increasing productivity with special assistance in certain areas, increasing planting in areas that have the potential to be changed as new rice fields, and intercropping with plantation crops, supported by policies inventory of existing conditions of agricultural land, optimization and revitalization of water management infrastructure, optimizing the use of agricultural machinery, securing the harvest, investment in land use management, improving agricultural and farmer safety, and  preparation of agricultural spatial plannin</span></em></em><em>g.</em></p>

Our spatial environment is one of the most important determinants of our well-being and life chances. It relates to schools, opportunities, businesses, recreation and access to public services. Spatial injustice results where discrimination determines that spatial environment. Since Apartheid in South Africa epitomised the notion of spatial injustice, tools and instruments are required to transform spatial injustice into spatial justice. One of these is the employment of principles of spatial justice. While the National Development Plan (NDP) recognised that all spatial development should conform to certain normative principles and should explicitly indicate how the requirements of these should be met, the Spatial Planning and Land Use Management Act 16 of 2013 (SPLUMA) contains a more concrete principle of spatial justice. It echoes aspects of both the South African land reform programme and global principles of spatial justice. Essentially section 7(a) of SPLUMA entails three components: (1) redressing past spatial imbalances and exclusions; (2) including people and areas previously excluded and (3) upgrading informal areas and settlements. SPLUMA directs municipalities to apply the principle in its spatial development frameworks, land use schemes and, most importantly, in decision-making on development applications. The aim of this article is to determine whether the application of this principle in practice can move beyond the confines of spatial planning and land use management to address the housing issue in South Africa. Central to housing is section 26 of the Constitution, that has received the extensive attention of the Constitutional Court. The court has not hesitated to criticize the continuing existence of spatial injustice, thus contributing to the transformation of spatial injustice to spatial justice. Since planning, housing and land reform are all intertwined not only the role of SPLUMA, but also the NDP and the myriad other policies, programmes and legislation that are attempting to address the situation are examined and tested against the components of the principle of spatial justice in SPLUMA.
