Code Snippets and Examples
Here are some code snippets that illustrate how programming can be used to address food security challenges:
Predicting Crop Yields with Machine Learning
This example demonstrates how to use Python and scikit-learn to predict crop yields based on historical data.
import pandas as pd from sklearn.model_selection import train_test_split from sklearn.linear_model import LinearRegression from sklearn.metrics import mean_squared_error # Load the dataset data = pd.read_csv('crop_data.csv') # Select features and target variable features = ['temperature', 'rainfall', 'soil_moisture'] target = 'yield' # Split the data into training and testing sets X_train, X_test, y_train, y_test = train_test_split(data[features], data[target], test_size=0.2, random_state=42) # Train the linear regression model model = LinearRegression() model.fit(X_train, y_train) # Make predictions on the test set predictions = model.predict(X_test) # Evaluate the model mse = mean_squared_error(y_test, predictions) print(f'Mean Squared Error: {mse}') Monitoring Soil Moisture with IoT Sensors
This example shows how to use Python and a Raspberry Pi to read data from soil moisture sensors and upload it to a cloud platform.
import RPi.GPIO as GPIO import time import requests # Define the GPIO pin for the sensor SENSOR_PIN = 17 # Set the GPIO mode GPIO.setmode(GPIO.BCM) GPIO.setup(SENSOR_PIN, GPIO.IN) # Define the cloud API endpoint API_ENDPOINT = 'https://api.example.com/soil_moisture' # Read the sensor data and upload it to the cloud try: while True: if GPIO.input(SENSOR_PIN): moisture_level = 'Dry' else: moisture_level = 'Wet' data = {'moisture_level': moisture_level} requests.post(API_ENDPOINT, json=data) print(f'Moisture Level: {moisture_level}') time.sleep(60) except KeyboardInterrupt: GPIO.cleanup() Node.js Example: Implementing a Food Supply Chain Tracker
This Node.js code snippet demonstrates how to create a simple API endpoint to track food products using a database.
const express = require('express'); const app = express(); const port = 3000; app.use(express.json()); const foodItems = [ { id: 1, name: 'Tomatoes', location: 'Farm A', status: 'Harvested' }, { id: 2, name: 'Lettuce', location: 'Farm B', status: 'Shipped' } ]; app.get('/food/:id', (req, res) => { const foodId = parseInt(req.params.id); const foodItem = foodItems.find(item => item.id === foodId); if (foodItem) { res.json(foodItem); } else { res.status(404).send('Food item not found'); } }); app.listen(port, () => { console.log(`Server listening at http://localhost:${port}`); }); These examples illustrate just a few ways in which programmers can contribute to global food security.
