「集中養豚システム」としても知られる集中養豚は、養豚産業における主要な養豚方法となっています。この方法では、豚は高い飼育密度で個別の小屋または藁を敷いた小屋に閉じ込められて屋内飼育され、同時に、同年齢の豚が共通の環境設定の下で大規模な群れとして生活する状態が保たれます。これにより、給餌効率が大幅に向上します。豚の健康を維持し、豚の成長を保護するために新技術が頻繁に採用されていますが、ワイヤレス温湿度センサーを使用した納屋内のさまざまな環境パラメーターの監視は、その好例です。

ニューサウスウェールズ州第一次産業省（NSW DPI）は、2018年に670万豪ドルの「Climate Smart Pilots」プロジェクトを開始しました。このプログラムでは、天然資源と気候変動に関して農家向けに生成される情報を改善するために、デジタル技術を試験的に活用しています。これには、漁業、園芸、畜産セクター全体が関係しています。温暖化が進み、降水型が変わり、季節にも変化が見られる中、革新的なモノのインターネット（IoT）技術を活用することで、早期の警報の発出、情報の制御、農業システムの新しい管理方法の導入などが可能になります。
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.

飢餓が世界中で地域社会を衰退させる
世界中で起きている飢餓は何百万もの人々が直面している極めて深刻な問題であり、その数は増加の一途をたどっています。世界では、約6億9000万の人々が毎晩空腹のまま就寝しており figure is expected to increase to 840 million people by 2030.
IHS Markit predicts up to 43 percent of all low power wide area networks (LPWANs) will be based on Semtech’s LoRa® devices and the LoRaWAN® protocol by 2023*. As of December 2019, more than half a million LoRa-enabled gateways have been deployed globally, supporting 135 million LoRa-based end nodes**. With the global adoption of Internet of Things (IoT) solutions and the growing market share of LoRa-enabled applications, it is becoming more and more difficult to identify a business segment that could not benefit from some level of connected devices. With new LoRa use cases being announced regularly, and growing numbers of worldwide LoRaWAN network deployments (public or private), it seems the only limit to these applications is the imagination of the developers and system integrators solving real world business challenges today.

Inconsistency in crop yield is a major concern for farmers. Even with green houses presenting a controlled environment for crop growth, pests and disease are unavoidable. Additionally, a farmer’s lack of knowledge on the conditions in the farm’s soil presents further challenges. The amount of fertilizer used on crops is often left up to the farmer’s discretion. This usually results in over- or under-dosing, which affects crop growth directly. Human error has the largest impact on a crop's yield, with inefficient or inconsistent irrigation and errors in fertilization having serious negative effects on crop health.
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.
Only 3% of the world’s water is accessible freshwater*. Of that, more than 600 gallons per day per person in the U.S. is being diverted for farm irrigation and livestock use. Monitoring soil moisture levels helps farmers to make effective and smart irrigation decisions. Too much water in the soil leads to waterlogged areas and a potential for plant illness or death, while too little water will harm crop growth.
