Flooding can cause a reduction of nitrates in the soil due to faster growth of nitrifying bacteria; drought can divert water away from farms; famine can lead farmers to eat seeds to survive; poor soil or lack of fertilizer reduces crop yield; desertification reduces farming areas; poverty limits the ability to buy seeds and essentials; war makes farming dangerous; urbanization reduces farming areas; increasing population increases food demand; pests damage yields; lack of farming education reduces yields and damages soil.
Oversvømmelser kan forårsage en reduktion af nitrater i jorden på grund af hurtigere vækst af nitrificerende bakterier; tørke kan være en årsag til afledning af vand væk fra gårde; hungersnød kan få landmænd til at spise frø på forhånd for at overleve; dårlig jord eller mangel på gødning kan reducere udbyttet af afgrøder; ørkenspecifikation reducerer landbrugsområder; fattigdom reducerer evnen til at købe frø og andre landbrugsartikler; krig kan gøre det for farligt at dyrke; urbanisering reducerer landbrugsområder; stigende befolkning øger fødev efterspørgsel; skadedyr kan beskadige udbyttet; mangel på landbrugskundskab reducerer udbyttet og kan beskadige jorden.

| Back | Flooding can cause a reduction of nitrates in the soil due to nitrifying bacteria growing faster, Drought can be a cause for diversion of water away from farms, Famine can cause farmers to eat seeds in advance to survive, Poor soil or lack of fertiliser can reduce yield of crops, Desertification reduces farming areas, Poverty reduces the ability to buy seeds and other farming essentials War can make it too dangerous to farm, Urbanisation reduces farming areas, Increasing population increases food demand, Pests can damage yields, Lack of farming education reduces yields and can damage soil. |
