Water, Land and Ecosystems

Water, Land and Ecosystems is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Water, Land and Ecosystems rather than just read about it. In short: Water, Land and Ecosystems is one of several new research programmes approved by the CGIAR during 2011 after an extensive period of consultation that began in 2009. This research programme will draw on the resources of 14 CGIAR and numerous external partners to provide a more integrated approach to research into managing natural resources.

Key takeaways

Water, Land and Ecosystems belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Water, Land and Ecosystems to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Water, Land and Ecosystems from memory before moving on to harder problems.

Reference excerpt

Water, Land and Ecosystems is one of several new research programmes approved by the CGIAR during 2011 after an extensive period of consultation that began in 2009. This research programme will draw on the resources of 14 CGIAR and numerous external partners to provide a more integrated approach to research into managing natural resources. The aim of the research programme is to increase agricultural productivity while protecting the environment, so food security is ensured for most of humanity and that poverty becomes history. The five main strands to the programme are: River basins; Irrigation systems; Information systems; Resource reuse and recovery; and Rainfed agriculture systems. A report released by UNEP and the International Water Management Institute (IWMI – which comes under the CGIAR umbrella and will be a major contributor to the new research programme), exemplifies the concept of conducting agriculture within healthy ecosystems. Current farming methods have resulted in over-stretched water resources, high levels of erosion and reduced soil fertility. According to the report, there is not enough water to continue farming using current practices; therefore how we use critical water, land, and ecosystem resources to boost crop yields must be reconsidered. The report suggested that we need to assign value to ecosystems, recognize environmental and livelihood tradeoffs, and balance the rights of a variety of users and interests. We would also need to address inequities that result when such measures are adopted, such as the reallocation of water from poor to rich, the clearing of land to make way for more productive farmland, or the preservation of a wetland system that limits fishing rights.

Worked examples

Example 1 — a first encounter with Water, Land and Ecosystems

Start with the simplest possible case. Write down what Water, Land and Ecosystems 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 Water, Land and Ecosystems 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 Water, Land and Ecosystems 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 Water, Land and Ecosystems

In research: Water, Land and Ecosystems 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 Water, Land and Ecosystems 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: Water, Land and Ecosystems is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural research, Natural resources, Research projects, so understanding it makes those chapters shorter.
In everyday life: Look for Water, Land and Ecosystems 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.
