This unit asks you to design a 100 km² Sustainable Land Plan optimizing across multiple objectives: yield, biodiversity, carbon, equity, livelihoods. You will defend your plan to a Regional Planning Board. The vocabulary below is the working language of land-use planning and ecology.
Vocabulary
| Term | What it means + visual cue | Sentence stem |
|---|---|---|
| Biodiversity | The variety of life in a place: species, genetic diversity, ecosystem types. Visual: Multiple plant and animal silhouettes in one frame. | Biodiversity in this region is ___ because ___. |
| Ecosystem services | The benefits humans get from ecosystems: clean water, pollination, carbon storage, flood control, recreation. Visual: Forest with arrows pointing to water, food, oxygen, climate. | A key ecosystem service in this region is ___. |
| Carbon sequestration | The process of capturing CO₂ from the atmosphere and storing it in plants, soil, or wood. Forests, wetlands, and grasslands all sequester carbon. Visual: Tree pulling CO₂ down into roots and soil. | Carbon sequestration potential here is ___ because ___. |
| Land cover | What physically covers the land: forest, grassland, cropland, urban, wetland, bare. Different from land USE (how it is managed). Visual: Patchwork map with color-coded land cover types. | Current land cover in this region is ___% forest, ___% cropland, ___% other. |
| Agroforestry | Combining trees with crops or livestock on the same land. Yields, biodiversity, and carbon all benefit. Visual: Field with rows of crops between rows of trees. | Agroforestry in this plan would mean ___. |
| Monoculture | Growing a single crop over a large area. Productive but vulnerable to pests and biodiversity-poor. Visual: Vast field of identical crop rows stretching to horizon. | Monoculture in this region creates ___. |
| Fragmentation | When continuous habitat is broken into smaller, disconnected patches by roads, fields, or development. Harms many species. Visual: Forest cut by a road into separated patches. | Fragmentation in this plan is reduced / increased by ___. |
| Restoration | Returning a degraded ecosystem to a functional state: replanting, removing dams, rewilding. Visual: Bare ground next to the same plot after replanting. | Restoration in this plan would target ___. |
| Succession | The natural change of plant and animal communities over time after a disturbance. Bare ground → grass → shrubs → trees. Visual: Time arrow showing landscape progressing from bare to forested. | Succession in this plan is allowed / accelerated by ___. |
| Trade-off | When improving one objective worsens another. The core of multi-objective planning. Visual: Seesaw with two competing objectives. | A trade-off in my plan is ___ vs. ___. |
| Multi-objective optimization | Designing for several goals at once, accepting that no single solution maximizes all. Find the best balance. Visual: Spider/radar chart with multiple axes. | My plan optimizes across ___, ___, and ___. |
| Conservation | Protecting natural habitats and species from degradation or loss. Different from preservation (no use at all). Visual: Fenced reserve with a "protected" sign. | Conservation in this plan covers ___% of the area. |
| Indigenous land use | Land management traditions developed by Indigenous communities over generations, often highly sustainable. Visual: Hand passing seed across multiple generations. | Indigenous land use in this region historically meant ___. |
| Yield | The amount of crop, timber, or product produced per unit area. Important but only one of several objectives. Visual: Grain harvest in a measured field. | Yield in this scenario is ___ metric tons per hectare. |
| Livelihood | The means by which people make a living. Land plans that ignore livelihoods rarely succeed politically. Visual: Family farming, fishing, and harvesting. | Livelihoods in this region depend on ___. |
| Stakeholder | Any person or group affected by or able to influence the land plan. Includes farmers, Indigenous communities, conservation groups, government, downstream users. Visual: Multiple figures around a planning table. | The stakeholders in this plan include ___, ___, and ___. |
Map sketch. I will give you a blank 10×10 grid representing 100 km². Sketch a land-use allocation: which cells are forest, crop, agroforestry, conservation, etc. Label using at least 6 vocabulary terms. We will compare allocations.
With a partner: each of you proposes one trade-off in your sketched plan. Defend why your trade-off is acceptable. Your partner challenges from the perspective of one stakeholder who LOSES in your plan.
