Burgeoning population and rapid urbanisation have contributed to two challenges facing cities today: food security and an increasing carbon footprint due to food imports. This paper examines the viability of rooftop farming in urban centres in Asia. A context-specific exploration—sited in Singapore—looks at the challenges of building integrated agriculture. Findings suggest that Singapore's public housing estates are suitable for rooftop farming. Implemented nationwide, such a scheme could result in a 700% increase in domestic vegetable production, satisfying domestic demand by 35.5%. Reducing food imports would also decrease Singapore's carbon footprint by 9,052 tonnes of emissions annually.

Organic farming occupies a unique position among the world’s agricultural systems. While not the only available model for sustainable food production, organic farmers and their supporters have been the most vocal advocates for a fully integrated agriculture that recognizes a link between the health of the land, the food it produces, and those that consume it. Advocacy for the biological basis of agriculture and the deliberate restriction or prohibition of many agricultural inputs arose in response to potential and observed negative environmental impacts of new agricultural technologies introduced in the 20th century. A primary focus of organic farming is to enhance soil ecological function by building soil organic matter that in turn enhances the biota that soil health and the health of the agroecosystem depends on. The rapid growth in demand for organic products in the late 20th and early 21st centuries is based on consumer perception that organically grown food is better for the environment and human health. Although there have been some documented trends in chemical quality differences between organic and non-organic products, the meaningful impact of the magnitude of these differences is unclear. There is stronger evidence to suggest that organic systems pose less risk to the environment, particularly with regard to water quality; however, as intensity of management in organic farming increases, the potential risk to the environment is expected to also increase. In the early 21st century there has been much discussion centered on the apparent bifurcation of organic farming into two approaches: “input substitution” and “system redesign.” The former approach is a more recent phenomenon associated with pragmatic considerations of scaling up the size of operations and long distance shipping to take advantage of distant markets. Critics argue that this approach represents a “conventionalization” of organic agriculture that will erode potential benefits of organic farming to the environment, human health, and social welfare. A current challenge of organic farming systems is to reconcile the different views among organic producers regarding issues arising from the rapid growth of organic farming.

The greenhouse fruit and vegetable production is one important area which supports sustainability. To achievesustainable economy and growth, the given natural resources have to be used in a smarter, renewable way in order to avoiddepleting them. New technologies and new methods are developed and implemented to utilize resources in more optimized way.Sustainable food supply is essential globally for the world, however it has to be managed and achieved on local levels. We presentthe greenhouse production market restructuring with new players. What kind of difficulties arise in the open field vegetableproduction and what benefits can be realized by the customers and producers from the covered greenhouse technology in thecontinental and desert climate? What are the technical boundary conditions to establish and operate greenhouse production indifferent regions and what are the benefits realized from local food production? As an example, we analyse Qatar’s energetics,climate conditions and food resources, Qatar’s food supply process and its barriers. We will show how the sustainability andfood safety appear in Qatar’s National Strategy Plan.

Low temperature industrial surplus heat represents a major energy source that is currently only rarely utilized due to its low quality. An agricluster allows for the leveraging of this low-quality heat and, hence, may improve the overall energy efficiency. This paper presents the novel concept of an agricluster driven by available surplus heat from industrial processes. We propose the integration of greenhouse production, insect rearing, fish rearing, and drying of seaweed using low temperature surplus heat from the aluminum industry. Each of these processes is already used in or investigated for utilization of surplus heat and partly coupled with other processes, such as in aquaponics. However, the integration of all processes in an agricluster—as proposed in this paper—may result in improved utilization of the surplus heat due to the different seasonality of the heat demand. The potential synergies of this integration approach are discussed in this paper. Furthermore, waste from one process can be utilized as an input stream to other processes, reducing the demand for external material input to the system. The proposed concept of an agricluster is especially interesting for the Nordic countries, as they are dependant on fresh food imports due to the low outside temperatures.

The effort of fulfillment over people's food is a constitutional obligation of the State.  The development of an increasingly large population can threaten the existence of the tropical wet forest area when opening the land needs of food became imperative. As was the case in East Kalimantan, the area of food land is diminishing because over the function of the land are massive for coal mining and palm oil plantations. This will bring up the feared conditions insistence to open forest areas to agricultural land of food.  The Central Government has the authority to make the national policy while the local government is based on the provisions of Division of the authority of Government, have the authority to make policies related to land protection food crop sector ongoing in the area. This article would like to know (1) How is the legal content in the regulation regarding the protection of sustainable food crop lands at the national level; and (2) how is regional can make a regulation of the protection sustainable food crop lands. The method is used the legal research of normative, as well as by the method of analysis is  analytic descriptive. Based on the results of the study it was concluded that the regulation of sustainable food crops land protection at the national level has been set in full, but the content of legal protection, there is a weakness in political designation, which allows agricultural lands sustainable food converted as long as there is not determination as a sustainable agricultural lands. In other words, the provision in The Law No 41 Of 2009 On The Protection Of Land For Sustainable Food  Plantation, but in substance precisely open up opportunities for the occurrence over the function of the land. there is a regulation on the region level regarding legal protection one of them the Regional Regulation No 1 Of 2013 On The Protection Of Sustainable Agricultural Lands, but contain elements of weakness that requires a determination of the agricultural lands before protection While official functionary who is not determination agricultural location does not get strict sanctions. This is a weakness for the agricultural land which has not been established, although physically it is the agricultural land of food, but because there is no designation then will not be affordable by the regulation of the area.

Falling world grain stocks, rising grain prices and the poor economic situation of Africa have, since 1995, made food security a major issue. Structural adjustment programmes, the crushing burden of debt, the collapse of commodity prices and mismanagement of national economies have rendered African people even poorer in terms of per capita income and quality of life than they were in the first decade after the attainment of independence. Yet Africa is rich in many ways — for example, in virgin land for agriculture and in mineral resources, including energy. It is rich above all in its people and their determined spirit to face all disasters, natural and man-made. In line with this spirit, Africa is moving ahead on a new consensus that food security through enhanced agricultural production is the continent's most fundamental development issue. Although the economic plans of successive African governments have stressed the goal of food self-sufficiency, the food sector has received little investment or political priority. Africa continues to rely on food aid and food imports, which consume a large part of its meagre export earnings. The increasingly limited capacity to purchase food abroad and the bitter experience of depending on emergency aid are honing a clear determination that Africa must marshal the resources to grow its own food and so release the creative energies of its people to contribute fully to their own development and well-being. Top priority should be given to food security during this process, as no country can consider itself free until it has the wherewithal to provide for the basic needs of its people.
