新南威尔士州基础产业部 (NSW DPI) 于 2018 年启动了耗资 670 万澳元的气候智能试点项目。该项目试验各种数字技术，以改善为渔业、园艺和畜牧业农户提供的自然资源和气候变化信息。随着气温变暖、降雨量变化和季节变化，创新的物联网 (IoT) 技术可以提供预警、输入控制和管理农业系统的新方法。
As one of the oldest industries, agriculture has existed for thousands of years in China. It is the foundation of the national economy and the most fundamental for China to achieve sustainable development. However, with the transformation of our economic structure in recent years, the agriculture industry is facing tough challenges posed by factors such as the increasing shortage of agricultural labor force (farmers increasingly turning to migrant workers), the improper use of fertilizers and pesticides, and the shortage of water resources. How to achieve refined, green and sustainable development of agriculture is the key problem to be addressed in China and even across the world.
世界数百万人面临着饥饿的威胁，而且数字还在不断上升。全球约 6.9 亿人每晚饿着肚子睡觉，而这一 figure is expected to increase to 840 million people by 2030.
IHS Markit 预测，到 2023 年，所有低功耗广域网 (LPWAN) 将有多达 43% 基于 Semtech 的 LoRa® 器件和 LoRaWAN® 协议*。截至 2019 年 12 月，全球已部署超过五十万个支持 LoRa 的网关，支持 1.35 亿个基于 LoRa 的终端节点**。随着物联网 (IoT) 解决方案的全球采用以及支持 LoRa 的应用的市场份额不断增长，将越来越难以找到无法从任何互联器件中受益的业务部门。新的 LoRa 用例定期发布，全球 LoRaWAN 网络部署（公共或私有）的数量不断增加，似乎对这些应用的唯一限制就是开发人员和系统集成商解决当今现实世界业务挑战的想象力。
In the past five years, farmers in the Cameron Highlands, which are located 250 kilometers from Kuala Lumpur, Malaysia, have taken the initiative to implement a simple monitoring system for their farms’ soil health. However, cost and connectivity presented a serious challenge for the farmers. Smarter solutions and machine-to-machine (M2M) services are often expensive and not available in rural areas. End users, typically the farmers themselves, are naturally very concerned with a solution’s power consumption, availability and reliability, as these factors directly affect the cost to deploy and operate these solutions. For the Cameron Highlands, the region’s various hills and valleys created additional challenges for service providers and reduced network signal strength. As a result, the farmers turned to solutions based on Semtech’s LoRa® devices and the LoRaWAN® protocol.
According to recent reports, between 70% and 80% of agricultural greenhouse-gas emissions, such as nitrous oxide, come from the production and use of nitrogen fertilizers. Farmers need real-time visibility into soil conditions while working in their fields. During growing season, manual soil tests fail to provide the data growers need and this can cause farmers to either over fertilize or under fertilize, harming profits and/or the environment. Teralytic, a manufacturer of wireless soil sensors, implemented LoRa® devices and wireless radio frequency technology (LoRa Technology) in its wireless sensor to detect nitrogen, phosphate and potassium (NPK) levels in soil to help farmers reduce waste and to improve crop yields.
世界上的水只有 3% 是可获取的淡水*。美国每人每天将当中的 600 多加仑用于农场灌溉和牲畜使用。监测土壤湿度有助于农户做出有效和明智的灌溉决策。土壤的水分过多会导致区域积水，可能令植物生病或死亡，而水分过少会损害作物生长。
