    • "The main crops grown include sugarcane, tea, cassava and corn, and rice and vegetables mainly for subsistence. The plantations are almost entirely rubber (Hevea brasiliensis), which, as with other parts of Yunnan, has expanded rapidly in recent years (Li et al. 2006; Ziegler et al. 2009), and now is a crop supporting many livelihoods in the area.

    • "Evidencing this limitation, extensive forest areas continue to be cleared for agriculture , as is currently happening in Asia for rubber plantations (Ziegler et al., 2009). Moreover, due to sea-level rise, many highly productive coastal areas will suffer saline intrusion into aquifers and will eventually be flooded (Ivins, 2009). "

    ABSTRACT: By 2050, human demand for food will increase by 70 %, or 5.4 thousand million tonnes per year. However, agriculture’s capacity to provide it is constrained by lack of additional land and freshwater, and is threatened by climate change. In response, this chapter explains how and why more seaweeds should be farmed at sea to supplement production of plant products from agriculture. There are no obvious technical or spatial barriers to such development and there are potential environmental benefits, such as bioremediation of coastal waters, creation of new fish habitat and sparing of land and freshwater that would otherwise be used by more agriculture. But, if it is to happen, maritime nations must be willing to allocate marine space for seaweed farms to be established, and affordable seaweed food products with broad consumer appeal must be developed. Early attempts to do this in a tropical developing country are described and give reason for optimism.

    • "However, this beneficial impact of traditional land use is only possible when the undisturbed old-growth forests exist as seed source for succession. This system is now in danger of collapsing due to increasing human population levels, more intense forest use and especially the large scale clearance of forest for rubber monoculture in our research area (Guo et al., 2002; Zhu et al., 2004; Li et al., 2006; Fu et al., 2009; Qiu, 2009; Ziegler et al., 2010). For biodiversity conservation purposes, we like to stress the urgent need for research in looking for effective forest use strategies that intermix with protected secondary, old-growth forests, and forests managed for local people use so that an optimal balance between economic development and biodiversity conservation can be reached.
