美国代写essay:农业可持续集约化

美国代写essay:农业可持续集约化。农业可持续集约化的第一个实践是有机农业。有机农业包括使用生物、农艺和机械方法来控制农药的使用,以使土壤肥力增强(Moris, Dhar和Agwe, 2006)。此外,这有助于消除用于提高作物产量的合成化学品。这可以通过对农民实施严格的政策来实现,包括对使用农药的处罚和对减少农药使用的生物和自然方法的奖励。虽然有机农业在许多国家正获得比杀虫剂农业更优先的地位,但主要的政策支持、价格支持和观念改变是推动有机农业升级为首选农业方式的主要因素。接下来美国代写essay专家将为同学们分析下农业可持续集约化。

根据联合国粮农组织(FAO)的数据,如果目前的人口趋势继续增长,世界粮食需求可能会增加到目前的60%(“可持续农业集约化”,2017年)。这就需要采取严肃的措施和全球政策干预,以遏制需求增长的步伐,遏制粮食生产所需的水、粮食和自然资源的持续浪费。过度的农业会对自然资源产生不利影响,如果再加上粮食浪费的增加,粮食生产和自然资源的保护可能会呈指数级下降。因此,农业的可持续集约化是必要的,也是不可避免的,必须在粮食需求超过供应之前尽早加以调整。

农业可持续集约化的第二个实践是精准农业,其中所有投入资源都是在彻底评估其生产力效益后使用的,利用最少的投入资源和学习提高作物产量的精准技术。通过技术投入、作物行为研究、土壤质量和季节变化,这些都可以得到加强。这需要大量的研究,但一旦实现,就可以用更少的资源产生类似或更多的作物产量。

As per the Food and Agricultural Organisation (FAO), if current trends of population continue to increase, world food demand could increase to 60% of what it is today (“Sustainable Intensification of Agriculture”, 2017). This calls for serious measure and global policy intervention to arrest the pace of increasing demand and reign in the continuance of wastage of water, food, and natural resources necessary for food production. Excessive agriculture can negatively impact natural resources, and when this is coupled with increase in food wastage, there could be an exponential decline in food production and conservation of natural resources. Hence, sustainable intensification of agriculture is necessary and inevitable to be adapted at the earliest before food demand overtakes supply.

The first practice of sustainable intensification of agriculture is organic farming. Organic farming involves using biological, agronomic, and mechanical ways of controlling pesticide usage to enable soil fertility (Moris, Dhar & Agwe, 2006). Moreover, this promotes elimination of synthetic chemicals for crop yield enhancement. This can come about by enforcing strict policies for farmers, involving penalties for using pesticides and incentives for biological and natural ways of decreasing pesticide usage. Although organic farming is gaining precedence over pesticide farming in many countries, major policy support, price support and perception change are primary to push for its escalation to a preferred way of farming.

The second practice of sustainable intensification of agriculture is precision agriculture, in which all input resources are used after thorough assessment of their productivity benefits, utilising minimum amount of input resources and learning precision techniques for maximising crop yield. These can be enhanced by technology inputs, research of crop behaviour, soil quality, and seasonal changes. These require a lot of researches, but when once achieved, it can generate similar or more amount of crop output with fewer resources as used before.
