Spatial as a contributor to biological productivity and ecosystem services have not been considered in the sustainable development of small islands. The aim of this study to appraise biocapacity (BC) in the Gili Matra Islands to estimate the existing carrying capacity for sustainable development, and refines the current BC methodology that emphasizes the spatial aspects in small islands. Based on analysis results, the Gili Matra Islands have BC total ranging from 659.46 to 1,069.57 gha in 2010, and increased from 673.64 to 1,093.02 gha in 2014. The highest total BC is the Gili Trawangan Island, while the lowest is the Gili Meno Island, but for the local BC is the opposite. The total local BC per island can be supplied around 0.00857 gha per capita for the Gili Ayer Island, 0.20103 gha per capita for the Gili Meno Island, and 0.00344 gha per capita for the Gili Trawangan Island. They are influenced by population density. The BC values indicate a critical position, both per-unit-area or per-capita, which is spatially nearly 100 % of the needs supplied from outside the island, and demonstrate the use on the Gili Matra Region have exceeded the existing carrying capacity. The sustainable development aspects and land use management should be applied strictly to ensure the sustainability of natural resources, social and economic, as well as cotinuously consider the efforts and existing strategies of conservation. The export and import factors of bioproductivity should be considered in making long-term planning. Spatially, BC appraisal was applicable to illustrate the condition of an area on the small islands. The GIS based BC can give the information of pattern of changes and distributions, both spatial and temporal. However, the statistical data use is needed to get the value of BC per capita.


Some communities have moved from the countryside to the city for different reasons, sometimes they have managed to settle in slums and some people go to agricultural production inside the city for their support, by means of a knowledge they bring from the countryside, seeking a place offering them useful resources to produce food, in this sense, urban agriculture as an alternative livelihood and occupation, has a symbolic value, since it is a survival strategy for families [3]. For this reason, this study was carried out within the macro project “Implementación del proyecto educativo comunitario salud alimentaria y productiva en el desarrollo sustentable de la invasión de la carrilera, corregimiento Campoalegre del municipio de Tuluá” (translated: “Implementation of the community educational project, food and productive health in the sustainable development of the invasion community La Carrilera, Campoalegre district of the municipality of Tuluá”), of the Health, Care and Society research groups; GIUR and Agricultural Production, which supported the characterization of the sociodemographic, cultural, environmental and agroecological components in the community of “La Carrilera” that aimed to evaluate and to identify the problems and needs of the study population, through the implementation of surveys, measurement of the biological quality of water based on the methodology used by IDEAM, Roldán and Shannon-Weaver, and the characterization of organic solid waste where the method defined by Marmolejo was implemented, resulting in the identification of the different social groups that make up the community, the occupation of women, the economic income of families, among others. In addition, the high levels of water pollution were manifested with a diversity index of 0.83, indicating the low diversity in the tributary of the community, also the BMWP index presented that the quality of the waters is critical and doubtful, and finally obtained an organic waste production of 60.1% identifying that mainly fruit and vegetable waste is produced. Subsequently, from the diagnosis obtained, some intervention strategies were determined for the conservation of the water resource and sustainable management practices for the use and transformation of organic waste in the study population, which allows adopting urban agriculture and contributing to sustainable development of the sector in the municipality of Tuluá, Valle del Cauca.

AbstractThis introductory chapter explains why organic waste composting is considered as one of the best examples to demonstrate the benefits of nexus thinking. Current literature is rich with information covering various aspects of composting process. However, it mainly represents two distinct fields: waste from the management point of view and soil/agriculture from the nutrient recycling point of view. It is hard to find information on how these two fields can benefit from each other, except for a few examples found within large agricultural fields/businesses. A policy/institutional framework that supports a broader integration of management of such resources is lacking: a structure that goes beyond the typical municipal or ministerial boundaries. There is a clear need to address this gap, and nexus thinking can help immensely close the gap by facilitating the mindset needed for policy integration. Good intention of being sustainable is not enough if there is no comprehensive plan to find a stable market for the compost as a product. Therefore, the chapter also discusses the strong need to have a good business case for composting projects. Composting can also support achieving the Sustainable Development Goals (SDGs) proposed by the United Nations. While directly supporting SDG 2 (Zero hunger), SDG 12 (Responsible consumption and production), and SDG 13 (Climate action), enhanced composting practices may also assist us reach several other targets specified in other SDGs. While encouraging waste composting as a sustainable method of waste and soil management, we should also be cautious about the possible adverse effects compost can have on the environment and public health, especially due to some non-traditional raw materials that we use nowadays such as wastewater sludge and farm manure. Towards the end, we urge for the improvement of the entire chain ranging from waste generation to waste collection/separation to compost formation and, finally, application to soil to ensure society receives the maximum benefit from composting.
