The poultry industry plays an important role in meat production/supply, with a growth rate of more than 4% p.a. in the last few years. This white meat production requires a large amount of feed that increases competition in the use of natural resources for primary food and other uses. Grains are the primary source of poultry nutrition and oilseeds are the most common protein source, with maize, wheat, and soybean being the most common ingredients in poultry diets. It is not clear to what extent natural resources are used to produce these feed crops and what the impact is of the resulting pressure on the availability of natural resources for other uses. The study evaluates and quantifies the local feed availability and the associated amount of local and non-local land and water resources required for the poultry production worldwide at a country and region scale as of 2016, including a detailed global feed trade analysis for the top poultry producer countries. Country-specific diets were used for the ten largest producer countries and two simplified diets for the global scale. The feed amounts were converted in land and water demand using crop-specific yields and a phisically based and spatially distributed hydrological model. The findings showed that 49 Mha of cereals (37 Mha local) and 64 Mha of soybean (25 Mha local) are needed to feed chickens globally, together with approximately 441 km3 of green water (197 km3 and 244 km3 for cereals and soybean, respectively) and 52 km3 of blue water (27 km3 and 25 km3, respectively) required by these feed crops in 2016. However, significant amounts of natural resources are saved through the international feed trade. The results obtained suggest the need for more sustainable approaches to address future projections in the sector.

全球鸡肉生产自然资源评估

家禽业在肉类生产/供应中发挥着重要作用,过去几年以每年超过 4% 的速度增长。这种白肉生产需要大量饲料,这增加了将自然资源用于初级食品和其他用途的竞争。谷物是家禽营养的主要来源,油籽是最常见的蛋白质来源,玉米、小麦和大豆是家禽日粮中最常见的成分。目前尚不清楚自然资源在多大程度上被用于生产这些饲料作物,以及由此产生的对自然资源可用于其他用途的压力的影响是什么。该研究评估并量化了截至 2016 年在国家和地区范围内全球家禽生产所需的当地饲料可用性以及当地和非当地土地和水资源的相关数量,包括对顶级家禽的详细全球饲料贸易分析生产国。十个最大的生产国使用了特定国家的饮食,全球范围内使用了两种简化的饮食。使用特定作物产量和基于物理和空间分布的水文模型将饲料量转换为土地和水需求。研究结果表明,全球养鸡需要 49 Mha 的谷物(当地 37 Mha)和 64 Mha 的大豆(当地 25 Mha),以及大约 441 公里 包括对顶级家禽生产国的详细全球饲料贸易分析。十个最大的生产国使用了特定国家的饮食,全球范围内使用了两种简化的饮食。使用特定作物产量和基于物理和空间分布的水文模型将饲料量转换为土地和水需求。研究结果表明,全球养鸡需要 49 Mha 的谷物(当地 37 Mha)和 64 Mha 的大豆(当地 25 Mha),以及大约 441 公里 包括对顶级家禽生产国的详细全球饲料贸易分析。十个最大的生产国使用了特定国家的饮食,全球范围内使用了两种简化的饮食。使用特定作物产量和基于物理和空间分布的水文模型将饲料量转换为土地和水需求。研究结果表明,全球养鸡需要 49 Mha 的谷物(当地 37 Mha)和 64 Mha 的大豆(当地 25 Mha),以及大约 441 公里2016 年这些饲料作物需要3的绿水(谷物和大豆分别为197 公里3和 244 公里3)和 52 公里3 的蓝水(分别为 27 公里3和 25 公里3)。通过国际饲料贸易节省了自然资源。获得的结果表明需要采取更可持续的方法来解决该部门的未来预测。
