What are the factors that contribute to the decline in agriculture?

Increased spring precipitation and higher temperatures and humidity are expected to increase the number and intensity of fungus and disease outbreaks. Increases in growing-season temperature in the Midwest are projected to be the largest contributing factor to declines in the productivity of U.S. agriculture.


Why is it important to increase humidity in agriculture?

Increased rainfull from April to June, an increase in the frost-free season due to an earlier last spring frost, and increasing humidity are all recent agriculturally important climate trends. The avoidance of heat stress and longer growing seasons have favored agricultural production in some parts of the region in some years. Increased precipitation provides a good supply of soil moisture, but reduces flexibility for the timing of spring planting and increases soil erosion. Increasing humidity has increased daily minimum temperatures in all seasons; an increase in water vapor (absolute humidity) has contributed to growing-season trends in both temperature and precipitation. Higher humidity decreases the day–night temperature range and increases warm-season precipitation. It also leads to longer dew periods and high moisture conditions, which favor many agricultural pests and pathogens for both growing plants and stored grain.


How does vapor pressure deficit affect plants?

Increased VPD has a drying effect on plants and soils , as moisture transpires (from plants) and evaporates (from soil) into the air. (a) Cooler air can maintain less water as vapor, putting less demand for moisture on plants, while warmer air can maintain more water as vapor, putting more demand for moisture on plants. (b, c) The maps show the percent change in the moisture deficit of the air based on the projected maximum 5-day VPD by the late 21st century (2070–2099) for (b) lower and (c) higher emission scenarios.


How will precipitation affect agriculture?

Changing precipitation patterns could also significantly impact agriculture in the Great Lakes. Future projections show that surface soil moisture will likely transition from excessive levels in spring, due to increased precipitation, to insufficient levels in summer, driven by higher temperatures causing more moisture to be lost through evaporation.


How does human activity affect the forest?

Impacts from human activities, such as logging, fire suppression, and agricultural expansion, have lowered the diversity of the region’s forests over time; forests with reduced diversity are at an increased risk of negative effects from climate change. In many forests, for example, fire suppression has decreased the prevalence of drought-tolerant tree species such as oak, hickory, and pine, while increasing the abundance of species such as maples, which have higher moisture requirements. As drought conditions increase, this may result in a greater risk of declines in forest health and productivity. As tree species at the northern limits of their ranges decline and southern species experience increasingly suitable habitat, changes in major forest types and composition are projected to occur—with the possibility that the ranges of particular tree species may not be able to shift to future suitable habitats.
