Overview of the model

There are different sectors that each one of them have a sort of physical governing equations and some interconnected input/outputs.

  • Climate
  • Agriculture
  • Livestock
  • Energy

Crop models: An overview

SIMPLE

Weather Data:

Crops: - Wheat - Bean - Corn

1.Crops list (plus Cultivar):

These parameters are crop-specific:

  • Species*,Tbase,Topt,RUE,I50maxH,I50maxW,MaxT ExtremeT,CO2_RUE,S_Water
  • sweetcorn,8,27,1.7,100,5,34,50,0.01,2

Cultivar specific:
- Species,Cultivar,Tsum,HI,I50A,I50B - sweetcorn,GSS0966 sh2,1900,0.45,500,250

2.Soil

  • SoilName*, AWC, RCN, DDC, RZD
  • Sand1, 0.07, 60, 0.7, 800

Description: I need some literature showing what the soil type of the region is.

3.Irrigation

  • No irrigation (0); all precipitation

Treatment: Weather

Historical:
Each region has its own weather file.

Treatment: Exp:

  • Exp*:

  • Trt* of a Exp*: {1,2,…,}

  • same Exp: same weather, same/different CO2, different sowing/harvest date

Energy Sector

U.S. Electricity Grid & Markets Three major interconnections constructs the U.S. energy network. Energy supply is consumed within each region and there is a limited power exchanges. Navajo Nation is located in the Western Interconnect.

There are two modes of power exchange: wholesale and retail, and in both the central region of the Western Interconnect is governed by a traditional regulation. This is while there are sub-sections of the country that operate the system with corporative comepetetive energy markets (i.e. the Northeast Midwest, Texas, and California). The traditionally regulated systems face more challenge in deploying renewable systems due the lack of market incentives. The energy forecast should consider the characteristics of this tyoe if energy ecosystem.

  • Arizona, Utah, and New Mexico are among the regulated states but in the future they might vote for deregulation.

Available data: - U.S. Energy Information Administration eia Input: - Case - Climate scenarios - Socioeconomic scenario - Policiy scenarios

Within the model: - Equation: Scenario to energy model projection

Output: - Change in demand of natural resources from the energy sector side

Total power supply Proportion of different energy sources
