Why is land important for agriculture?
Land – a notion which broadly includes climate, topography, vegetation, soils and other natural resources – is the basis for agriculture, and the interaction between these components is vital for determining the productivity and sustainability of agro-ecosystems. Especially in the face of climate change and variability, selecting the right land uses for given biophysical and socio-economic conditions is essential for minimizing land degradation, rehabilitating degraded land, ensuring the sustainable use of land resources, and maximizing resilience.
What is the distribution of agricultural land?
Regional distribution of agricultural land use is a combination of local agri-climatic edaphic – soil –conditions, and socio-economic drivers.

How does animal agriculture affect the world?
Industrialized animal agriculture rules the world’s current food system and is responsible for widespread habitat destruction, including rainforests, harmful air and water pollution, the extinction of species (including those who have yet to even be scientifically identified by humans), and it contributes greatly to climate change, adding more harmful greenhouse gas emissions to the atmosphere than the entire transportation sector combined. And as this research has detailed, many crops are grown to feed livestock rather than feeding the world’s millions of starving people.

How can farmers increase agricultural productivity?
Farmers could increase agricultural productivity by boosting crop yields — either through new farming techniques or through improved crop genetics. But even if the rapid rate of improvement in crop yields over the 20th century continued, that still wouldn’t produce enough food for everyone. Another possibility, as the map above shows, is …
