Reference excerpt

Plantas alimentícias não convencionais (PANC) (lit. 'non-conventional food plants'), is an academic and popular education agroforestry botany movement, specially in Brazil and Latin America, of open research and social marketing for uncommon edible plants, mainly those that self-breed without harvesting efforts in empty lots and roads that have nutritional properties. Due to the advances in modern agriculture and changes in cuisine, several plants that were historically cultivated are no longer utilized, and may be pejoratively referred to as weeds. These, usually native species, are often resistant to pests, need little wild gardening care, and can be grown in unconventional places, such as small closed rooms, roadsides, or vacant lots with very few resources.

History In 2007 the term was coined by Valdely Kinupp, in his Ph.D. thesis in botanics by the Federal University of Rio Grande do Sul, which later became a seminal work in the field. Since PANCs are site specific, so varying from region to region, he created the Isto é PANC? group to help identify edible plants. In 2010, the Brazilian Ministry of Agriculture released the Manual de hortaliças não convencionais (Manual of non-conventional vegetables). This book compiled 23 vegetable species with edible parts, and assists in the use and partial identification of PANCs. In 2017, the Food and Agriculture Organization has accepted it as an open standard for family agriculture and is available in several sources online for download as an open educational resources.

Examples Basella alba can be eaten sautéed, cooked or raw. Maranta arundinacea has rhizomatous stems from which a starch can be extracted. Ora Pro Nobis (Pereskia aculeata). Tropaeolum majus is entirely edible above ground, including the seeds.

Worked examples

Example 1 — a first encounter with Plantas alimentícias não convencionais

Start with the simplest possible case. Write down what Plantas alimentícias não convencionais claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Plantas alimentícias não convencionais before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Plantas alimentícias não convencionais ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Plantas alimentícias não convencionais

In research: Plantas alimentícias não convencionais appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Plantas alimentícias não convencionais in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Plantas alimentícias não convencionais is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural economics, Agriculture in Brazil, Foraging, so understanding it makes those chapters shorter.
In everyday life: Look for Plantas alimentícias não convencionais outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
