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.

Mycorrhizal enhancement in Peruvian potato production

World Region
Interventions

The influence of arbuscular mycorrhizal fungi (AMF) [two Peruvian mixed isolates, a pure isolate of Glomus intraradices] and the flavonoid, formononetin, were tested on growth, yield, and leaf elemental concentration of the Peruvian potato (Solanum tuberosum L.) ‘Yungay’. Non-AMF plants at low P had the poorest growth, while high P plants had the greatest overall […]

Adoption of sweet potato for food and feed in mixed crop-livestock systems

World Region

Interventions
,

Mixed crop–livestock systems have a crucial role to play in meeting the agricultural production chal- lenges of smallholder farmers in sub-Saharan Africa. Sweet potato is seen as a potential remedial crop for these farmers because of its high productivity and low input requirements, while its usefulness for both food and feed (dual-purpose) make it attractive […]

Intercropping benefits depend upon proximity

World Region
Outcomes
,
Interventions
,

There are numerous examples of crops that, when planted closely in intercropped systems, make better use of soil ntrients. In China, Wheat intercropped with maize showed a 74% increase in yields; Wheat intercropped with soybean showed a 53% increase (Zhang and Li 2003).  This is partially attributable to ‘competitive recovery’, the amelioration of abiotic stresses both […]

Self Sufficiency through Integrated Crop Livestock Systems in Brittany

World Region
Outcomes
,
Interventions
, ,

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 […]

Shifting from cattle ranching to Integrated Crop-Livestock Systems in Amazonia

World Region
Outcomes
, , ,
Interventions
,

A grazing system based on one species (Brachiaria brizantha, representing 90% of sown grass in Amazoni)  with Nelore zebu cattle, is adapted to marginal regions with little need for inputs, but income per hectare remains low. Integrated Crop and Livestock Systems in Amazonia can generate higher income per ha and stop deforestation. The system, which involves […]

Bottom up and top down effects impact herbivore abundance

Threat
Outcomes
Interventions
,

In a replicated oilseed rape field, trophic cascades governing herbivore abundance are correlated with both top down and bottom up affects. This study investigates whether a basic invertebrate classification, formed of broad trophic groups, can be used to describe interactions between invertebrates and their resource plants and evaluate management impacts for genetically modified, herbicide-tolerant (GMHT) […]

Shifting cultivation and agrobiodiversity in Vanuatu

World Region
Threat
Interventions
, , ,

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 […]

Adapting to climate-driven fishstock fluctuations in African inland fisheries

World Region
Interventions
,

The contribution of fish production from inland production has risen from less than 25% in 1951 to 41% in 1994. These fish stocks are climate-driven and cannot be stabilized using conventional fisheries management measures. However, the livelihood strategies of fisherfolk are adapted to seasonal and inter-annual climate-induced fluctuations. State management, which fails to recognize the […]
