Ugbo: Ask Your Farm in Pidgin, Go Outside

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass. For most people, “touch grass” is a joke. For millions of smallholder farmers in Nigeria, the grass is the job, and getting it wrong costs a season.

这是 Hacktoberfest 开源 AI 挑战赛第一周的参赛作品：接触土地（Touch Grass）。对大多数人来说，“接触土地”只是个玩笑。但对于尼日利亚数以百万计的小农户而言，土地就是他们的工作，一旦判断失误，就可能损失整个季节的收成。

The question every farmer asks at this time of year is simple: “Rain don start. Make I plant maize now?” Plant too early, on a false start, and the seedlings die in the dry spell that follows. Wait too long and you miss the window. The answer depends on how much rain actually fell in your village, what’s coming this week, and what the season allows for your crop.

每年这个时候，每个农民都会问一个简单的问题：“雨季开始了，我现在可以种玉米吗？”如果因为误判雨季开始而过早播种，幼苗会在随后的干旱期枯死；如果等待太久，又会错过播种窗口。答案取决于你所在村庄实际的降雨量、本周的天气预报，以及该季节适合种植的作物。

That information exists, but it lives in English-language weather apps and extension PDFs, not in the languages farmers speak. Ugbo (Igbo for “farm”) is a voice-first weekly field plan. A farmer picks their town and crops, asks a question in Nigerian Pidgin, Hausa, Yorùbá, Igbo or English, and Ugbo: Checks the real rain at their village for the last 14 days and the next 7; works out what the season allows for each crop in their zone (South, Middle Belt, North); speaks back a short plan in a Nigerian voice, ending with the one job to do in the field today.

这些信息虽然存在，但大多隐藏在英语天气应用程序和推广手册的 PDF 中，而不是农民所使用的语言中。Ugbo（在伊博语中意为“农场”）是一个以语音为主的每周田间计划工具。农民只需选择所在的城镇和作物，用尼日利亚皮钦语、豪萨语、约鲁巴语、伊博语或英语提问，Ugbo 就会：核查其村庄过去 14 天和未来 7 天的实际降雨量；计算出该地区（南部、中部地带、北部）各作物在当前季节的适宜性；并用尼日利亚口音播报简短的计划，最后给出今天在田间必须完成的一项工作。

The screen is the shortest part of the experience. Ask, listen, go to the farm. A real answer for Suleja (Niger State), maize and yam, this week: See your week for Suleja. Rain wey fall for the last 14 days: 85 mm. Rain wey go fall for the next 7 days: 17 mm. The soil don wet well well. How sure: I sure. For your maize, na time to harvest. For your yam, na time to harvest… The main work for today: Waka round your farm, check for weed and insect.

屏幕操作只是整个体验中最简短的部分。提问、聆听、下地干活。以下是针对尼日尔州苏莱贾（Suleja）地区玉米和山药种植本周的真实回答示例：查看苏莱贾本周情况。过去 14 天降雨量：85 毫米。未来 7 天预计降雨量：17 毫米。土壤水分充足。确定性：非常确定。对于玉米，现在是收获季节。对于山药，现在也是收获季节……今日主要工作：在农场周围走走，检查杂草和害虫。

Why Does Open Innovation Matter? Because the people Ugbo is for are the people closed AI forgets. Nigerian languages exist in open models because Nigerians built them. NaijaVox, Naija TTS and MMS exist because researchers fine-tuned and released open weights for Pidgin, Hausa, Yorùbá and Igbo. No closed speech API I looked at understood a Pidgin farm question as well, and I couldn’t have fine-tuned one if it didn’t.

为什么开放式创新很重要？因为 Ugbo 所服务的对象正是封闭式 AI 所遗忘的人群。尼日利亚语言之所以存在于开源模型中，是因为尼日利亚人构建了它们。NaijaVox、Naija TTS 和 MMS 之所以存在，是因为研究人员针对皮钦语、豪萨语、约鲁巴语和伊博语进行了微调并发布了开放权重。我所研究过的任何封闭式语音 API 都无法像这样理解皮钦语的农事问题，如果它们不支持，我也无法进行微调。

I can make the model behave. With open weights I control the whole pipeline: the prompt, the fact check, the fallback. I can guarantee Ugbo never states a number the rules didn’t produce. That matters more than eloquence when the advice is about someone’s harvest.

我可以让模型按预期运行。通过开放权重，我控制了整个流程：提示词、事实核查和备选方案。我可以保证 Ugbo 绝不会提供规则之外的数据。当建议关乎某人的收成时，这一点比语言的华丽程度重要得多。
