This presentation outlines why the future of agriculture must adapt to climate change and water shortages, and why co-operation is essential. It introduces wicking beds as a practical horticultural system designed to deliver water, air, nutrients, and microbes to plant roots with high efficiency. It also explains why water will become the critical resource for food production, why living soil matters, and why soil biology and micro-hydrology are central to land repair, carbon capture, and resilience.
The Future of Agriculture (未來農業)
The core theme is simple: agriculture is entering a period where old assumptions no longer hold. The presentation frames the future of agriculture around two connected pressures:
- Adapting to climate change (適應氣候變化)
- Adapting to water shortages (水資源短缺)
These are not separate challenges. Climate change reshapes rainfall patterns, shifts growing seasons, increases heat stress, and raises the risk of drought. At the same time, human demand for water rises due to population growth, urban expansion, and competing industrial uses. The outcome is that food production will be forced to do more with less water, while still producing nutrient-dense crops.
Problems in Common, and an Invitation for Co-operation
The presentation highlights that many regions share “problems in common”, and therefore need to share solutions. It makes an explicit invitation for co-operation (邀請合作). In practice, this means:
- Sharing knowledge about water-efficient systems.
- Testing practical approaches that work at household scale and at farm scale.
- Building systems that reduce risk during drought and heat events.
This approach is not about a single “perfect” technology. It is about improving outcomes step by step: faster learning, better systems, and cheaper delivery of results.
Faster, Better, Cheaper (更快、較好、更便宜)
The phrase “Faster, Better, Cheaper” appears as a guiding principle. In simple terms:
- Faster: solutions must be implementable now, not in decades.
- Better: they must improve plant health, soil function, and productivity.
- Cheaper: they must be affordable enough to scale, from home gardens to farms.
This sets the tone for the rest of the content: practical horticulture that can be widely adopted, especially where water is limited.
Part 1: Overview of Wicking Beds (第1部分：排汗床概述)
Wicking beds are presented as a key horticultural system. The idea is to create a growing environment that supplies plants with what they need, consistently and efficiently. The presentation reduces the system to four essentials:
- Water (水)
- Air (空氣)
- Nutrients (營養素)
- Microbes (微生物)
These four elements are treated as a single integrated system rather than separate inputs. If one is missing or out of balance, plant health declines. If they are balanced, plants grow strongly with fewer problems.
How Wicking Beds Work (如何排汗床工作)
The central mechanism is a water reservoir under the soil. Water moves upward through capillary action (“wicking”) into the root zone. This creates a controlled moisture gradient:
- Saturated at the reservoir level.
- Moist through the main root zone.
- Drier near the surface.
This gradient matters. It reduces evaporation from the surface, because the top layer is not constantly wet. At the same time, roots can access reliable moisture below. The presentation describes this as water wicking up to the root zone from an underground reservoir, providing a gradient from saturated in the reservoir to dry at the surface.
Continuous Supply: Water, Oxygen, and Nutrients
When soil remains at a stable “moist-but-not-waterlogged” level, roots can function properly. The presentation states that roots growing in moist soil can have a continuous supply of water, oxygen, and nutrients.
This is important because roots need oxygen to respire. In poorly designed irrigation systems, soil cycles between too dry (roots stressed) and too wet (oxygen limited). A well-made wicking bed aims to reduce those extremes and keep plants in a steady growing state.
A New Horticultural System, and Why It Is Important
The presentation explicitly calls wicking beds a new horticultural system and asks “Why is it important?”
The importance is framed around resilience and efficiency. Where water is scarce or unreliable, any method that reduces evaporation losses and delivers water directly to where it is used (the root zone) becomes more valuable. This is not only about yield. It is about stability: keeping plants alive and productive through heat, wind, and dry spells.
Part 2: Fears About Future Food Production (第2部分：對未來糧食生產的恐懼)
The presentation then broadens to the global context and the reasons for concern.
Climate Shift (氣候變化)
Climate shift is presented as a major risk driver. In practical terms, climate shift can mean:
- Rainfall arriving in fewer, heavier events rather than steady patterns.
- Longer hot periods that increase evaporation and plant stress.
- Greater unpredictability from season to season.
These changes increase the value of systems that store water, protect it from evaporation, and make it available steadily to plants.
Competition for Water (對水的競爭)
The presentation makes the point clearly: competition for water is rising.
Agriculture often uses a large share of available freshwater, but it also competes with cities, industry, and environmental needs (rivers, wetlands, ecosystems). As this competition intensifies, agriculture will face limits. That is why the presentation states directly that:
“Water will be the critical resource for future food production.”
This is the core “future constraint” that shapes every other decision: what crops are grown, where they are grown, and what production methods are viable.
How Real Is the Threat of Food Shortages?
The presentation raises the question of how real the threat is.
The purpose of this question is to shift thinking from short-term comfort to long-term preparedness. Food systems depend on stable water, stable climate, functioning soils, and predictable logistics. When any of these become unstable, shortages become more likely, even if they appear suddenly and unevenly across regions.
Genetically Modified Drought and Temperature Tolerant Plants
The presentation asks whether we can develop genetically modified plants tolerant to drought and temperature.
This is framed as a possible strategy, but it is not presented as the only strategy. Even if plant genetics improve, the system still depends on water availability, soil function, and the biology that supports healthy root systems. In other words, plant traits can help, but they do not replace the need for water-smart growing methods and living soil.
The Role of Soil (土壤的作用)
The presentation then turns to soil as a central factor.
Soil is not treated as “dirt”. It is treated as a living, functioning system that affects water storage, nutrient availability, disease pressure, and long-term productivity. When soil structure collapses or soil biology is damaged, plants become more dependent on external inputs and more vulnerable to stress.
Pathogens and Disease (病原體和疾病)
Pathogens and disease are listed as key issues.
In practice, disease pressure increases when plants are stressed (heat, drought, nutrient imbalance) and when soils are biologically depleted. The presentation’s focus on microbes and living soil is, in part, a response to this: healthier soils tend to support healthier plants with fewer severe outbreaks.
Pioneering Species and Competition (創業物種和競爭)
The idea of pioneering species and competition is included to describe how ecosystems behave when land is disturbed or degraded.
When soil is weakened, opportunistic species often dominate. This can show up as weeds taking over, pest cycles becoming more severe, and desired crops struggling to compete. The implied solution is to rebuild soil function so that the desired plants can thrive without constant intervention.
Living Soil (生活土壤)
“Living soil” is highlighted explicitly.
Living soil means soil that contains active microbial life and functional organic matter. It means the soil can:
- Hold water more effectively.
- Cycle nutrients steadily rather than in spikes.
- Support root health and resilience.
This links directly back to the earlier “four essentials” (water, air, nutrients, microbes). The system is designed to support all four at once.
Soil and Climate: A Short-Term Lever
The presentation makes a strong claim: soils are the only solution that offers short-term impact on global warming.
It then expands that idea: experts agree that only soils can sequester significant amounts of atmospheric carbon in the next 30 years, and that other solutions take a long time to shift meaningful volumes.
The intent here is not to dismiss other approaches, but to focus attention on what can change quickly at scale. Soil carbon is directly linked to soil organic matter, which is linked to microbial activity, which is linked to water management. If soil is rebuilt, it can store more carbon and also grow better food with less water stress.
Climate Change in Australia (澳大利亞氣候變化)
The presentation includes a specific section on climate change in Australia.
Key Targets for Australia
Three main targets are listed:
- Protect the Southern food production area from increasing aridity.
- Develop new agricultural land as the tropical summer rain belt moves further south.
- Accept that some agricultural land has to be “aborted”.
These points are blunt, but practical. They suggest that climate adaptation is not only about improving methods. It may also involve changing where food is produced and acknowledging that some areas will become less viable over time.
Irrigation and Local Water Harvesting
The presentation also notes that irrigation areas are fully developed and highlights local water harvesting schemes.
This reinforces the earlier idea of competition for water: if large-scale irrigation expansion is limited, then smarter capture, storage, and use of local water becomes essential. Wicking bed technology and micro-hydrology concepts fit directly into that direction.
Part 3: The Importance of Micro Biology (第3部分：微觀生物學的重要性)
The presentation moves from water and climate into biology and land condition.
Land Degradation (土地退化)
Land degradation is listed as a key issue.
Degradation often includes loss of organic matter, loss of soil structure, reduced infiltration, reduced microbial diversity, and increased erosion. When land is degraded, it becomes harder for rainfall to soak in and easier for water to run off and be lost. That is why water and biology are linked.
Soil Regeneration (土壤再生)
Soil regeneration is presented as the pathway forward.
Regeneration is not a single action. It is a process of rebuilding the conditions that allow soil life to thrive. That includes protecting soil from extreme drying, keeping roots in the ground where possible, adding organic inputs, and using water in a way that supports microbial activity.
No Single Solution: Use a Combination of Methods
The presentation states: “No single solution must use a combination of methods.”
This is a critical mindset. It suggests that successful adaptation will combine:
- Better water storage and delivery (such as wicking systems).
- Living soil and microbial regeneration.
- Local water harvesting and landscape-level hydrology improvements.
- Practical tools that farmers and gardeners can actually adopt.
Water Plays a Crucial Role
The presentation repeats the message: water plays a crucial role.
Micro Biology Regenerates Soil
It then states directly: “Micro biology regenerates soil.”
This is the bridge between productivity and ecology. If microbial life is supported, soils rebuild. If soils rebuild, water holding and nutrient cycling improve. If water holding and nutrient cycling improve, crops become more resilient and productive with fewer inputs.
Part 4: Micro Hydrology (第4部分：微水文)
Micro-hydrology is introduced as a practical, on-the-ground way to influence water behaviour in landscapes.
Sturt and Simpson Deserts, and the Importance of Micro Hydrology
The presentation references the Sturt and Simpson deserts and highlights the importance of micro-hydrology.
The core idea is that small changes to how water is captured, directed, and stored can have outsized effects over time, especially in dry environments.
Percolation Holes (滲流洞)
Percolation holes are listed as a technique.
In simple terms, percolation holes are designed to help water move into the soil rather than running off the surface. If water can enter the ground, it can be stored, used by plants, and protected from evaporation.
Water Amplification (水擴增)
Water amplification is introduced as a concept: using design to concentrate and protect water so it does more work.
The Key Features
The presentation lists three key features of this approach:
- Amplify water into a concentrated area (把水集中到一個區域)
- Transport water underground (把水送入地下)
- Store water underground to protect from evaporation (地下儲水以防蒸發)
These three points are consistent with the wicking bed model: store water below ground, keep it protected, and deliver it where roots can reach it.
Part 5: Sources of Water (第5部分：水源)
The presentation signals a section on sources of water.
While the slides are brief in text, the overall narrative suggests that future water planning will rely on multiple sources and smarter capture. The repeated emphasis is on storing water in ways that reduce evaporation losses and increase availability for plants and soil biology.
Part 6: The Wicking Bed Technology (第6部分：毛細床技術)
The presentation introduces “the wicking bed technology” as a dedicated section.
At the heart of this technology is a design philosophy: deliver water efficiently, support living soil, and create stable growing conditions. This is positioned as a practical response to climate and water constraints, not as a theoretical model.
Applications (應用)
The slides include an “Applications” section.
In context, applications can be understood broadly:
- Home food gardens seeking reliability in dry spells.
- Community gardens needing lower water demand.
- Market gardens needing consistent crop quality.
- Broader regenerative systems where water and soil biology are treated as core assets.
Carbon Capture and Paying Farmers
A later section is titled “Carbon capture” and includes a clear policy-style statement:
Paying farmers to absorb carbon ensures our future food supply and offsets our energy use.
This point connects economics with ecology. If farmers are incentivised to rebuild soils (and therefore sequester carbon), the results can include:
- More resilient food production.
- Improved soil water holding capacity.
- Greater nutrient cycling and biological stability.
- A measurable climate benefit through increased soil carbon.
In the presentation’s logic, this is a practical pathway to align public benefit (climate and food security) with farmer profitability.
