Finally, it is important to put the impact of hydro and mining on access to land in the context of broader pressures on natural resources. Pressures on agricultural land include: transformations caused and influenced by land-forest allocation (LFA), village consolidation and relocation, the development of plantations (growing, for example, rubber, teak, eucalyptus, corn, cassava, and jatropha), the timber industry, and the development of protected areas. These changes are part of a broader strategy for poverty alleviation. However, an increasing body of research literature argues that the outcomes of these transformations sometimes involve significant economic, social, and environmental trade-offs, which are at times inconsistent with their objectives. Pressures on biodiversity include: overexploitation, illegal harvest and habitat destruction, and fragmentation due to agro-industry. The building of new roads, transecting forests and conservation areas, may also encourage the illegal wildlife trade. Pressures on wild fisheries include: unsustainable fishing practices (including the use of small nets and poison), the introduction of exotic fish species into natural wetlands, the conversion of wetlands into rice fields, the illegal hunting and trading of wetland wildlife, the use of pesticides, increasing threats of pollution, and increasing sedimentation of rivers because of land degradation due to large-scale plantations and shifting cultivation. A better understanding of these policies and the socioeconomic trade-offs involved is essential in order to understand how the impact of mining and hydro will interact with these existing pressures and changes.
