Landraces of major food plants, such as maize, provide agroecological and consumption resources within cultural landscapes that can support social-ecological resilience, in situ conservation, and ecosystem services. Locally This study addressed the major agroecological functions and food-related services of agrobiodiversity in Andean maize landraces, and their relationship to cultural landscapes and associated knowledge systems. Results […]
In situ conservation is an important strategy to maintain traditional and locally adapted varieties, particularly in their centers of domestication. Local farmers in different regions have demonstrated that landraces can coexist with high yielding varieties, particulary in highly heterogenous environments and cultures with local preferences for diversity. Particularly in centers of crop domestication and diversity, […]
Prosopis africana is very important for farming and pastoralist communities in the West African Sahel. The species extends from the relatively humid Sudanian and Guinean ecozones in the south to the drier Sahelian ecozone in the north, but it is disappearing in many regions due to overexploitation and the increasingly hotter and drier climate in the region. In the semi-arid West […]
In grassland plots, synergies between grasses and legumes benefit biomass production, while grazing animals fulfill three functions; harvest and distribute their own feed; return nutrients to the soil, and help to control weeds, thus minimising mechanical interventions and costs of fuel. Grazing management is the key to the efficiency of this system; the grassland is […]
In Vanuatu, farmers prefer to work numerous small fields in different locations and as a mechanism to cope with hurricane and pest damage. Shifting cultivation, a widespread cultivation system in the tropics, is also practiced and helps to maintain a high diversity of primary and subsidiary crops. 297 fields in 6 villages were measured and […]
In the communities around Lake Victoria, Kenya, diversified farms oscillate between activities in fishing, farming and livestock herding. These activities have become inextricably linked over many generations, with positive impacts upon household nutritional security.
In Northeastern Spain, artisanal Galician fisheries utilize a number of strategies in their fishing activities and livelihoods. These include: drawing upon a diversity of species fishing in a diversity of locations utilizing a diversity of fishing gear The seasonal income that fishing provides supplements the incomes of a range of people in other professions ranging […]
Family fishery operations are able to maintain flexibility through employing a number of different strategies. These include diversification of target species, gear types and fishing areas, buffering income uncertainties with supplier credits, diversifying into other types of employment or wage labor, and drawing upon community networks for cheap and unpaid assistance during times of need.
Local crop varietal diversity provides farmers with an important strategy for reducing pest and disease damage. Success is also dependent on their local knowledge and ability to utilize this diversity appropriately against different threats. On farm experiments, performed across a range of four sites in different agro-ecological areas showed that an increase in the diversity […]
Ethiopia is a centre of diversity for durum wheat, and farmers manage a high range of varieties in their plots. In the Tigray region, which is susceptible to drought, variable precipitation and land degradation, varietal richness in wheat fields is demonstrated to increase farm productivity, and reduce yield variability, especially for very high levels of […]
