Preserving Landraces: A Comprehensive Guide to Safeguarding Genetic Diversity

Landraces represent a crucial component of our planet’s biodiversity. These locally adapted, traditional varieties of domesticated species have evolved over time through natural and human selection. They are often associated with specific regions, cultures, and farming practices, and are a treasure trove of genetic diversity.

The Role of Landraces in Agriculture

Landraces have been the backbone of agriculture for thousands of years. They have adapted to local conditions, such as climate, soil type, and pests, and have been shaped by the cultural practices of the people who cultivate them. This makes them resilient and reliable, even in challenging environments.

The Threat to Landraces

Despite their importance, landraces are under threat. Modern agricultural practices often favor uniform, high-yielding varieties, which can lead to the loss of landraces and the valuable genetic diversity they contain. This loss is not just a threat to biodiversity, but also to food security and the resilience of agricultural systems.

The Need for Preservation

Preserving landraces is not just about conserving the past; it’s about safeguarding the future. The genetic diversity contained in landraces can provide the raw material for breeding new varieties that can withstand the challenges of climate change, disease, and pests.

How to Preserve Landraces: A Step-by-Step Guide

Step 1: Identification and Collection: The first step in preserving landraces is to identify and collect them. This involves working with local communities, who have intimate knowledge of the landraces they cultivate. It’s crucial to respect and acknowledge this knowledge, and to ensure that the benefits of preservation are shared with these communities.

Step 2: Documentation: Once collected, each landrace should be thoroughly documented. This includes recording its name, the location where it was collected, its characteristics, and any cultural practices associated with its cultivation. This information is crucial for understanding the landrace and its potential uses.

Step 3: Conservation: There are two main approaches to conserving landraces: in situ and ex situ. In situ conservation involves protecting the landrace in its natural habitat, while ex situ conservation involves storing seeds or other plant material in a gene bank. Both approaches have their advantages and are often used in combination.

Step 4: Utilization: Preserving landraces is not just about storing them away for a rainy day. It’s also about using them. This can involve breeding new varieties, reintroducing landraces into cultivation, or using them in research. The ultimate goal is to ensure that the genetic diversity they contain is utilized for the benefit of all.


Preserving landraces is a vital task that requires the collaboration of farmers, scientists, and policymakers. By working together, we can ensure that these valuable resources are not lost, but are preserved and utilized for the benefit of current and future generations.
