But, again, its diffusion is limited by geography and climate. ![]() Conversely, for example, rice originates in lowland tropical areas and it has historically been relatively easy to adopt farming technologies from one rice-growing region to another. Some crops, like wheat, grow only in temperate areas, so relevant advances in breeding or plant productivity might be relatively easy to diffuse across similar agro-ecological environments but will not naturally transfer to tropical environments, where most of the world’s poor reside. One of the primary reasons why agriculture’s diversity is so important to understand is that it defines the possibilities, and limits, for the diffusion of relevant technologies. Still others provide physical materials-like cotton or rubber-that provide valuable inputs to physical manufacturing. Other plants provide stimulants or medication that humans consume-such as coffee or Artemisia-but have no caloric value. Some plants provide food-such as grains, fruits, or vegetables-that people or livestock can consume directly for metabolic energy. Focusing solely on crop species, each plant grows within a particular set of respective conditions. It can be defined very simply, as at, as “the science or occupation of cultivating land and rearing crops and livestock.” But underneath that definition lies a vast array of landscape ecologies and climates in which different types of plant and animal species can grow. For example, agriculture and shifts in land use are responsible for roughly a quarter of greenhouse gas emissions.Īs a single word, the concept of “agriculture” encompasses a remarkably diverse set of circumstances. Agriculture is similarly important when considering environmental challenges like protecting biodiversity and tackling climate change. The majority of the world’s extremely poor people still live in rural areas, where farming is likely to play a central role in boosting average incomes. ![]() Twitter nature of agriculture is especially important when considering the tantalizingly imminent prospect of eliminating extreme poverty within a generation.
