TPS is a nonprofit service organization dedicated to families with scarce economic resources on less-fertile hill-lands in the American, African and Asian Humid Lowland Tropics (tropical lands with over 1500 mm rainfall/yr and under 900m elevation).

The Mission of TPS is to assist organizations in the Humid Lowland Tropics with the development and transfer of priority practices that have low external inputs, that improve food security and that improve the productivity, sustainability, profitability and biodiversity of mixed traditional crop-livestock-forestry production of families with scarce economic resources on less-fertile hill-lands (lands not suitable for specialized agro-industrial production).

The Founding Director of TPS is Dr. John P. Bishop who for over 40 years studied and worked with traditional diversified crop-livestock-forestry production on less-fertile hill-lands in over 20 countries in the American, African, and Asian Humid Lowland Tropics.

The Vision of TPS is to improve the commercial crop-livestock-forestry production of families with scarce economic resources on less-fertile hill-lands in the Humid Lowland Tropics---which is essential for food security and an improved rural development that is economically more equitable, sociologically more just, and ecologically more sustainable.

Technical Note - Collection of Two Native Cultivars of Phaseolus lunatus f. microcarpus in the Guatemalan Humid Lowland Tropics.

This Technical Note reports on the seed collection of 2 native cultivars of the “Sieva” group, during the major dry period in years 2008 and 2009. The cultivars were collected in the Humid Lowland Tropics in Southeastern Guatemala in Q’eqchi’ Mayan communities in the regions of Sumach-Rio Pita, Izabal (150-300 m elevation; 2000-2500 mm rainfall/yr) and Teleman-Salac, Alta Verapaz (300-600 m elevation; 2000-2500 mm rainfall/yr). The Q’eqchi’ Mayan name for these cultivars is “Frijol Tapakal”. (Wilk, 1997; Sam, et al, 2003) The Q’eqchi’ Mayan population is estimated to be over 1,400,000, and is currently the world’s largest Tropical Rainforest Ethnic Group.
