Long Term Agroecosystem Research Overview

Agriculture faces tremendous challenges in meeting multiple, diverse societal goals, including a safe and plentiful food supply, climate change adaptation/mitigation, supplying sources of bioenergy, improving water/air/soil quality, and maintaining biodiversity. The LTAR network enables long-term, trans-disciplinary science across farm resource regions to address these challenges. The goal of this research network is to ensure sustained crop and livestock production and ecosystem services from agroecosystems, and to forecast and verify the effects of environmental trends, public policies, and emerging technologies. Ultimately, LTAR is expected to provide a wide array of clients, partners, and stakeholders with four basic outcomes:
  1. Agroecosystem productivity is sustainably enhanced by the development and application of new technologies
  2. Mitigation and adaptation of agroecosystems to climate change is improved by more accurate predictions of resource responses to system drivers
  3. Stronger linkages to other long-term research networks improves conservation and environmental quality in agricultural landscapes
  4. The socio-economic viability of, and opportunities for, rural communities are enhanced through educational outreach by LTAR scientists and collaborators

Datasets

71 datasets

SMES Vegetation Line Intercept Data

NAL Geospatial Catalog

    This is data for perennial plant vegetation canopy cover measured from all SMES study plots, fall 1995. The purpose of this data is to provide ground-truth data for comparison with low-level aerial photographs of each study plot.

    SMES rodent trapping data

    NAL Geospatial Catalog

      The purpose of this study is to determine whether or not the activities of small mammals regulate plant community structure, plant species diversity, and spatial vegetation patterns in Chihuahuan Desert shrublands and grasslands.

      JER standard gauge monthly precipitation data

      NAL Geospatial Catalog

        The objective of this long-term project is to measure the precipitation across the entire Jornada Experimental Range. This is achieved by using a network of standard-can rain gauges to continually collect the precipitation as it occurs.
