Intervention Success Stories Productive Land Use Systems Project
(2024-04-04)
This report presents some pictorial and descriptive highlights of Productive Land Use Systems Project accomplishments. Selected land use techniques promoted by the Project are described and estimates of their impacts on ...
Linking prescribed fire, nutrient deposition and cyanobacteria dominance through pyroeutrophication in a subtropical lake ecosystem from the mid Holocene to present
(2023-11-09)
Prescribed fire (Rx-fire) is a common management tool for many forested ecosystems and promotes tree and forest soil health. Although burned materials from Rx-fire areas can enter adjacent aquatic environments, very few ...
Comparison of probabilistic post-processing approaches for improving numerical weather prediction-based daily and weekly reference evapotranspiration forecasts
(2023-03-04)
Reference evapotranspiration (ET0) forecasts play an important role in agricultural, environmental, and water management. This study evaluated probabilistic post-processing approaches, including the nonhomogeneous Gaussian ...
Raw and post-processed ensemble forecasts of crop reference evapotranspiration over the CONUS produced with NWP
(2023-03-04)
Database with raw and post-processed ensembles of summer crop reference evapotranspiration forecasts over the CONUS based on numerical weather predictions (NWP). The forecasts consider single or multi-model NWP from The ...
Dataset for: Sediment and Nutrient Transport Through a Reservoir Sequence Along a Large River System
(2023-03-04)
Reservoirs are highly effective at sequestering both sediments and sediment-bound nutrients, such as silts and phosphorus (P), but are also capable of depositing significant quantities of nutrients with more complex ...
PHYSICAL MEASUREMENTS IN SUBSURFACE HYDROLOGY
(2022-10-14)
Measurements needed to define the basic hydraulic properties of subsurface porous media constitute a fundamental problem. Complex mathematical flow models can only make realistic predictions if the correct values for the ...
Can texture-based classification optimally classify soils with respect to soil hydraulics?
(2022-10-14)
[1] In the past, texture-based classification of soils has been used for grouping soils in
variably saturated water flow and solute transport studies. Classification of soils becomes
especially important for large-scale ...
Alterations to sediment nutrient deposition and transport along a six reservoir sequence
(2021-04-26)
Reservoir presence and construction has become commonplace along rivers due to the multitude of ecosystem services they provide. Many services are well recognized, including the effectiveness of sequestering both sediments ...
Bwa yo: important trees of Haiti
(2020-03-02)
Trees and their forest habitats have played a major role in creating a fertile environment in Haiti. The ecological fabric that has nurtured the soil and supported life for millennia gradually has been unraveled by human ...
Report 20. Storage conditions and pre-germination methods for seed of selected tropical tree species
(2019-10-03)
This document summarizes tree seed storage conditions and pre-germination methods of major species utilized in Agroforestry II, a USAID funded agroforestry project in Haiti.
The study is not meant to be an exhaustive ...
Report 10. Impact des haies vives sur la production agricole
(2019-10-03)
Declining yields and land degradation are becoming more dramatic every year in spite of increasing foreign aid. Population growth far exceeds food production capacities. However, the effects of all agricultural development ...
Report 25. Time rate of discounting and decisions of Haitian tree planters
(2019-10-01)
During previous research on the economics of agroforestry in Haiti, it was noted that some farmers practicing agroforestry tended to hold onto trees for some years. They deferred harvesting them because some tree products, ...
Report 17. Assessment of hedgerow performances in the Haitian context
(2019-10-01)
Hillside farming in Haiti is practiced primarily by small farmers, and measures must be taken to help them at least maintain or possibly improve their production capacity. The introduction of techniques, such as hedgerow ...
Adoption and management of alley cropping in Haiti
(2019-10-01)
Haiti, a hilly densely populated country, has experienced soil erosion problems for decades. The major impact is a reduction of soil fertility leading to decreasing agricultural productivity. Agriculture, a major sector ...
Adoption of rock walls as a soil conservation structure in Haiti
(2019-10-01)
Land degradation has been identified as one of the most serious ecological, environmental, and economic problems facing the Haitian society today. One particular problem is soil erosion. Throughout the 19th century, ...
Report 21. Factors affecting seedling mortality in Haitian agroforestry
(2019-09-18)
This study examined several factors influencing the mortality of samples of seedlings used in the Agroforestry II Project. Measurements were made of the rootball condition, leaf drop, plant turgor and internal box temperatures ...
Report 19. Biological, physiological and environmental factors affecting the health of trees important to Haiti
(2019-09-18)
This report contains an extensive, although not necessarily complete, listing of biological, physiological and environmental factors which can affect the health of trees in genera important to the people of Haiti. These ...
Report 16. Soil profile description for selected sites in Haiti
(2019-09-18)
Reliable recommendations for the development of agroforestry systems require accurate descriptions of the environment. Information on the properties of soils in selected sites is needed to expand agroforestry in regions ...
Report 15. An explorative approach for assessing soil movement on hillsides. Application for hedgerow performance
(2019-09-18)
This report describes a methodology for studying soil movement on hillsides in Haiti. Hedgerows are one of the methods used in Haiti to prevent land degradation, and the method described here can be used to assess its ...
