必须把重点放在促进农业的可持续来源、甲烷的发酵、肥料的管理、水稻的种植和土地利用的变化。这是由于气候变化是最重要的因素。农业生产对环境的不利影响主要集中在化学利用方面，特别是农药和矿物肥料(Acton, 2012)。农业生产的环境影响扩大了进一步扩大农业领域的风险，如森林和反映生物多样性高价值的其他土地。此外，如果实施旨在遏制气候变化的严格政策，对生物质能的需求可能会大幅增加。

很明显，抑制生物能源和粮食驱动的农业扩张对保护全球生物多样性和自然生态系统至关重要(联合国，2013)。有限的扩张对于减缓全球碳排放，如将森林转化为牧场和农田是至关重要的。限制用于生产牲畜的土地的面积约占农业用地总使用的80%。因此，它被认为是减少牲畜对环境的影响的主要方法。人们相当一致地认为，增加现有农业用地的产量是减少额外扩张的主要因素。

There must be placement of specific emphasis on promoting sustainable sources of agriculture, fermentation of methane, management of manure, cultivation of rice and changes in land use. This was done since climate change was realized as the most significant factors. Majority of the adverse environment impacts of agricultural production are in association of chemical utilization, specifically with respect to pesticides and mineral fertilizers (Acton, 2012). The environmental effect of agricultural production amplifies the risk involved in further expanding agricultural area as forests and other areas of land reflecting high values of biodiversity. Further ahead, if stringent policies focused to curb change in climate are implemented, there can be a dramatic increase in the demand for biomass energy.

It is clear that curbing agricultural expansion driven by bio-energy and food is crucial for the conservation of global biodiversity and natural ecosystems (United Nations, 2013). The limited expansion is specifically essential to mitigate global emissions of carbon such as converting forests as pastures and cropland. Limiting the area of land utilized for production of livestock is specifically accounted for approximately 80 per cent of total use of agricultural land. It is considered consequently as a major approach to reduce the environmental impact of livestock. It is considerably agreed that increased yields over current agricultural land are major elements to minimize additional expansion.
