Reference excerpt

Isaya Kisekka is a Ugandan American agricultural engineer who is a professor at University of California, Davis. His research looks to make farmers more productive, efficient, sustainable and profitable. He has pioneered the development of precision irrigation systems. His work has been recognized by the American Society of Agricultural and Biological Engineers and the National Institute of Food and Agriculture.

Early life and education Kisekka was born in Kampala, Uganda. He studied agricultural engineering at Makerere University. He moved to the United States for graduate studies, joining the University of Florida. His masters explored evapotranspiration irrigation for tropical fruit in Florida. The evapotranspiration approach looks to apply the correct amount of water at the perfect time, then maintain soil water content in an idea range. His doctorate explored the modeling of groundwater and surface water interactions in South Florida. He developed the concepts into an open access website, sharing data on how to grow crops with less groundwater. These technologies were deployed on pistachio orchids near Fresno and Davis, striking a balance between latent heat, evapotranspiration and carbon sequestration. He has argued that challenges of deploying remote sensors is that no one agrees on standards or numbers, whilst ground-based measurements are expensive.

Research career Kisekka develops water management strategies and technologies to help farmers become more profitable and productive. He has developed precision irrigation systems (including sustainable microirrigation systems and low-pressure sprinkler systems) for the production of almonds, alfalfa, corn, processing tomatoes, pistachios, sorghum etc. He has developed integrated sensing systems for soil and plant water status to optimize irrigation, nitrogen, and salinity. Groundwater is increasingly important during heat stress and multi-year droughts. Kisekka looks to build links between policymakers, researchers, farmers and the general public about water demand management. In 2022, Kisekka was awarded $10m from the United States Department of Agriculture National Institute of Food and Agriculture to improve agriculture and groundwater quality in the Southwestern United States. The funding, which recognizes the changing climate in Southwest America, allows Kisekka to develop tools for water management at farm and basin scales and contribute to the Sustainable Groundwater Management Act. Part of his program looks to educate people from elementary school up to communicate the importance of water in agriculture. He wants to help farmers grow food in California without drying out their groundwater aquifers. Alongside groundwater, Kisekka has monitored how climate-driven extreme weather events impact the toxicity of drinking water. In 2020, Kisekka was honored by the Irrigation Association with the Excellence in Education Award. He was awarded the 2022 Netafim Award for Advancements in Micro-irrigation from the American Society of Agricultural and Biological Engineers.

Worked examples

Example 1 — a first encounter with Isaya Kisekka

Start with the simplest possible case. Write down what Isaya Kisekka claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Isaya Kisekka 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 Isaya Kisekka 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 Isaya Kisekka

In research: Isaya Kisekka appears in astronomy 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 Isaya Kisekka 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: Isaya Kisekka is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century African-American academics, 21st-century American academics, African-American engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Isaya Kisekka 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.
