| Demand is rising for organic vegetables in Vietnam. This poses many challenges for small-scale rural farmers who supply the Hanoi markets. Strict third party certification is well beyond their reach, both in terms of cost and technical ability. Organic participatory guarantee systems (PGS) offer an alternative through peer-review and social control, supporting appropriate farming practices, local market development, and social cohesion (Zanasi and Venturi 2008). PGS is based on civil society (Fonseca et. al, 2008), and ensures agro-biodiversity conservation and livelihood security by recognizing the merits of traditional practices and customs (Darlong 2008). PGSs are context specific and the systems vary greatly, but all propose collective efforts for... |

| Ugandan homegarden systems are sustainable small-scale solutions for food security and conservation containing a great diversity of native plant species and preserving the associated time-tested traditional knowledge for nutrition and conservation. Furthermore, the people of Uganda have a diversity of uses for these native species. However, these systems and traditions are under threat for a variety of reasons. Organic may hold some of the keys for the revitalization of these oases of diversity and culture. The organic markets in Uganda now sell only a few species but can embrace the great diversity through increasing access to organic markets for more small producers and indigenous plant species. |

| In a farmers' survey within Organic Participatory Guarantee Systems (PGS) in Soc Son Hanoi, Vietnam farmers indicated that they feel there is room for improvement, but that they are largely satisfied with the management schemes and farming systems. They gave a high score for questions related to the principles; health 74%, ecology 79%, fairness 68%, and care 71%. These results are outlined and the case is made that the organic principles are measurable and comparable. It is further argued that with a quantifiable measurement of the functioning of organic systems from the farmer we may find more ways to promote and help shape the future of the movement according to the principles. |

| The mountainous northwest of Vietnam is home for the majority of the country’s ethnic minorities. Poverty and food insecurity are common in the region, increasing population and land scarcity have induced the expansion of agricultural areas and consequent decline of land productivity due to soil erosion and land degradation. Local farmers have begun to practice agroforestry through the introduction of high value trees into traditional cropping systems with various combinations of timber, fruit, nut forage trees and annual crops. However, because of inherent production risks and many remaining uncertainties, assessing the long-term performance of agroforestry has remained challenging. We simulated prospective system benefits of agroforestry options by... |

| Large areas of salt-affected soils are found in tropics, especially in Africa, South America and the Middle East. While soil salinity might lead to food insecurity in those regions and affect farmers who are most vulnerable to environmental stress, however, little is known how the abiotic stress can be managed with locally available resources without involving high cost. Decades of practical evidence have demonstrated the benefits of the farm input, called biodynamic preparation 500 (P500) cow horn manure, such as improving crop performance and providing resilience against various stress conditions. Organic agriculture is already seen as an important issue in sustainable crop production in the tropics, but also biodynamic philosophy and agricultural... |
