Abstract:
Good quality water and arable land are required for both domestic and agricultural uses. Increasing population leads to urbanization and industrialization increasing the need to share these resources and creating threats to the food supply. Higher meat consumption requires mitigation strategies to protect food and mitigate economic crises, especially in developing nations. The production of food crops for energy purposes and lower yield due to climate change increase food prices as well as have a negative impact on the economy. Thus, an alternative food source is required featuring high forage components to reduce grazing periods and to prevent rangeland degradation. Halophytes can tolerate high salinity and can be easily grown for fodder in coastal areas where fodder is a problem. Varied climate conditions offer opportunities to grow suitable halophytes for specific purposes. One important feature is their use as fodder. To reduce food shortages, saline areas could be used to grow nutritive and productive halophytic forage. Wild plants have undesirable metabolites produced in harsh conditions which may be harmful for ruminant health. Halophytes have moderate amounts of these metabolites which are nontoxic. Halophytes can be grown without intruding on agricultural lands and freshwater resources and could promote livestock production which may improve the socio-economic conditions of poor farmers in a sustainable and ecofriendly manner.
摘要:
家庭和农业用途都需要优质的水和耕地。人口的增加导致城市化和工业化,增加了共享这些资源的需求,并对粮食供应构成威胁。更高的肉类消费需要采取缓解策略来保护粮食和缓解经济危机。尤其是在发展中国家。用于能源目的的粮食作物的生产和由于气候变化而导致的单产下降增加了粮食价格,并对经济产生了负面影响。因此,需要一种具有高牧草成分的替代食物来源,以减少放牧时间并防止牧场退化。盐生植物可以耐受高盐度,并且可以在饲料存在问题的沿海地区轻松种植饲料。不同的气候条件为特定目的种植合适的盐生植物提供了机会。一个重要特征是它们用作饲料。为了减少粮食短缺,盐碱地可用于种植营养和生产性盐生草料。野生植物具有在恶劣条件下产生的不良代谢物,其可能对反刍动物健康有害。盐生植物具有适量的这些无毒代谢物。盐生植物可以在不侵入农田和淡水资源的情况下种植,并可以促进畜牧业生产,从而以可持续和生态友好的方式改善贫困农民的社会经济状况。
