SFRI’s goal is for the sustainable use of soil and water to promote soil health.  It aims to accomplish this goal by researching measures to combat soil erosion and improve the fertility of agricultural soils.  Specifically, studies examine soil moisture conservation, the relationship between rainfall and runoff, and the effects of macro-and micro-nutrients on agricultural production.

SIDT is a community project of the FSPI aimed at rehabilitating reefs through coral gardening.  The project focuses on restoring reef areas degraded by coral harvesting and rehabilitating and restoring fish habitats damaged by harmful fishing methods.  In the past, the project involved training for coral farming, but currently, the cultured corals are used for restoration work.

The Spannocchia Foundation’s mission is to encourage global dialogue about sustaining cultural landscapes for future generations.  Some of its areas of interest include natural resource conservation, local ecology, sustainable agriculture and forestry, traditional land management practices, and farm based education.  The Spannocchia Foundation’s activities occur at its estate in a protected area in Maine.  Activities include study tours, tourism, cultural programs, conservation programs, and organic farming. 

SPREC is dedicated to the generation and dissemination of new information about protection, management and marketing of post harvest agricultural commodities and value added products.  The website does not note any current work around organic post harvest processes, but SPREC has previously demonstrated an interest in the area.

The Laboratory’s mission is to determine principles and practices that support the development of sustainable agricultural systems.  It has a current research project that aims to improve the economic status of organic farmers and improve their ability to meet consumer demand.  One of their objectives is to develop strategies that lead to improved productivity, enhanced soil and water conservation, and efficient nutrient cycling.

Under the auspices of the Sustainable Agriculture Program, the Sustainable Agriculture Network is an international coalition of conservation groups ensuring that farmers protect wildlife and wild lands.  Promoted farming methods include reducing water pollution, soil erosion, agrochemical use, and waste production, as well as wildlife habitat protection.  The Network is most active in countries in the tropics. 

SARD-M aims to strengthen the livelihoods of mountain populations with improved policies for sustainable development.  The Project aims to facilitate the design, implementation and evaluation of new policies for Sustainable Agriculture and Rural Development in mountain regions by raising awareness on the role and value of mountain ecosystems and building national capacity to promote and support mountain communities and ecosystems. 

SARNISSA aims to link individuals interested in aquaculture throughout Sub-Saharan Africa and beyond.  The webpage hopes to strengthen alliances between languages (English and French) and across borders in order to build on the existing knowledge resources base, the Aquaculture Compendium.  The extensive website contains information regarding, among other things, research and employment openings, opportunities for PhD and other postgraduate students, and recent journal publications.

SFI is an independent charitable organization dedicated to the promotion of sustainable forest management.  It has developed a forest certification standard that is used widely across North America and has a strong acceptance in the global marketplace.  The organization works with conservation groups, local communities, resource professionals, landowners, and others to promulgate sustainable forest management practices.   SFI collaborates with its partner organizations to support research in sustainable forest management and conservation efforts. 

SAFO was an EU funded Concerted Action, which was carried out between 2003 and 2006.  The objective of SAFO was to improve food safety and animal health in organic livestock production systems through exchange and active communication of research results and conclusions between researchers, policy makers, farmers and consumers.  Although the project has competed, the website includes various publications of relevance, including conclusions and recommendations and the proceedings from SAFO workshops on certification and standards, quality and safety, animal health, animal husbandry, and socio-economic aspects of organic animal production.
