The agricultural industry plays a crucial role in the global economy, and increasing agricultural productivity is essential to meet the growing demand for food. Agtech entrepreneurs have the potential to drive significant productivity growth in the agricultural sector by taking on greater risks than large corporations and by rapidly testing innovations, compared to larger, more established corporations. However, scaling these innovations from proof of concept to profitable market shares requires the support of a large business ecosystem with diverse stakeholders, including investors, policymakers, and researchers.
Understanding the complexity of the agricultural landscape is vital for fostering innovation. Distribution networks in agriculture are often intricate, customer relationships rely on trust and can span generations, and product development timelines can extend over several years. Therefore, analyzing regional ecosystems that support agtech entrepreneurship is crucial to identify opportunities and challenges for both entrepreneurs and the entities interacting with them.
A comprehensive understanding of the agtech ecosystem in a local context can have many benefits. It can help identify functional gaps and opportunities that entrepreneurs and other stakeholders can address. By expediting the necessary relationships, the ecosystem can facilitate the successful commercialization and widespread adoption of innovative goods and services. It also allows startup founders to leverage existing supporting resources and to explore potential relocation or new market locations. Investors seeking agtech companies in which to invest can also benefit from a well-defined ecosystem. Policymakers can make informed decisions that positively impact entrepreneurs, investors, and the community.
The Nebraska Agtech Ecosystem Map, a localized case study conducted in collaboration with researchers at the Daugherty Water for Food Global Institute (DWFI) at the University of Nebraska and The Combine by Invest Nebraska, provides a concise visual representation of the various players and resources that make up the state’s agtech landscape and the interconnections between them. In doing so, the map enables stakeholders to identify potential synergies and areas for improvement, while fostering innovation, communication and collaboration.
DWFI researchers have extended the global reach of their work and demonstrated the importance of understanding the broader context in which agtech entrepreneurs operate. In Rwanda, they explored the business ecosystem for smallholder irrigation, focusing on ways to support entrepreneurs who are developing affordable and accessible irrigation solutions for small-scale farmers. Similarly, a DWFI study of agtech startups and the business ecosystem for agricultural water use in India has shed light on the regional-specific challenges and opportunities facing entrepreneurs.
As the world faces the challenges of climate change, population growth and resource scarcity, fostering a thriving agtech ecosystem is key to driving agricultural productivity growth. By supporting entrepreneurs and start-ups and having a clear understanding of the space in which they operate, we can unlock the potential for innovation and create a more sustainable and resilient agricultural sector. Mapping and analyzing local business ecosystems, visualizing them effectively and understanding broader contexts are essential steps in this process. By working together, stakeholders can create an environment that nurtures agtech entrepreneurship and accelerates the development and adoption of innovative solutions to address the challenges facing agriculture today.

Yield and total factor productivity are ratios of outputs to inputs, but they are not the same, and the distinction matters.
Yield measures output per unit of a single input, for example, the amount of crops grown on a hectare of land. Yields can increase through productivity growth, but they can also increase by applying more inputs, called input intensification. Therefore, an increase in yield may or may not represent improvements in sustainability.
Total factor productivity captures the interaction between multiple agricultural inputs and outputs. (Ortiz-Bobea et al., 2021) TFP growth indicates that more farmers generate more crops, livestock, and aquaculture products with the same amount or less land, labor, fertilizer, feed, machinery, and livestock. As a result, TFP is a powerful metric for evaluating and monitoring the sustainability of agricultural systems.
