it also greatly increases costs of production and continues problems of “profit squeeze” 8.2 Human Geography and Climate Change – Agriculture Climate is closely associated with agriculture: it defines the length of the growing season, average temperatures and the amount of timing of precipitation Warming will likely reduce food production due to increased heat stress. Even slight increases in temperature will likely reduce crop yields Changing weather and precipitation patterns will alter agricultural patterns Changes in weather patterns and warmer average temperatures are likely to modify pests and diseases relative to crops and livestock, impacting economic activities and livelihoods Increasing temperatures will increase evapotranspiration and lower soil moisture levels Developing world is far more likely to experience negative impacts from the climate change – rainfall can be uneven While climate change is not expected to reduce overall global food availability, it will impact crop production, the distribution of food crops and food security and availability In the face of declining crop yields, many developing countries will become increasingly dependent on food imports Chapter 9: The Politics of Territory and Space Development of Political Geography: Long established sub field Artiste is taken to be the first political geographer because his model of the state is based on such factors as climate, terrain, and the ratio between population and territory Geopolitical Model of the State: Geopolitics: the states power to controls space or territory and shape foreign policy of individual states and international political relations Ratzel and Darwin describe the growth of the state was 7 laws: 1. Territory of the state grows with expansion of the population having the same culture 2. Territory growth follows other aspects of development 3. A state grows by absorbing smaller units 4. The frontier is the peripheral organ of the state that reflects the strength and growth of the state (not permanent) 5. States in the course of their growth seek to absorb politically valuable territory 6. Impetus for growth comes to a primitive state from a more highly developed civilization
