Resources and Breeding systems in Laya, Bhutan

World Region

The yak (Bos grunniens) is the main source of livelihood for the high-altitude communities of Bhutan; it provides a way of life for approximately one-tenth of the country’s population. Yak milk and dairy products fetch premium prices. Yaks were the main vehicle for trade with China until the border was closed in the late 1950s. […]

The System of Rice Intensification (SRI) is becoming widely adopted in many African and Asian countries because, compared with standard rice management (SRM), it consistently achieves increases in output alongside reductions in inputs of seeds, agrochemicals, water, energy and labour. SRI uses specific crop and water management practices that favour aerobic soil environment, root growth […]

Intercropping benefits depend upon proximity

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 […]

  Aquaculture is the fastest growing food producing sub-sector in the world, particularly in developing countries, with total aquaculture production nearly tripling between 1987 and 1999. In Asia, widespread adoption of aquaculture on traditional farms have demonstrated improved productivity, and additional sources of income and nutrition for the household. Aquaculture contributes to food and nutritional […]

Wetland agriculture can be negatively impacted by both drought and flood cycles. In Sanjiang Plain, China, researchers demonstrated that a highly diverse rice-reed-fish system, coupled with drainage and diversion, could reduce vulnerability and build resilience for farmers. Benefits of this system included product diversification, increased yields, and mitigated the impacts of floods and droughts while […]
