PDC LESSON 1.2 PRINCIPLES OF ENERGY CYCLING

 

Stop the flow of nutrients and energy off-site, and instead turn them into cycles.

Every cyclic event increases the opportunity for yield. To increase cycling is to increase yield. Assist rather than impede natural biogeochemical cycles (carbon, nitrogen, phosphorus potassium, hydrological, etc.)

Use incoming energy (sun, water, wind, manures, etc.) as its highest possible use, and then it’s next highest, and so on.

EXAMPLE

Dams and swales to collect and hold water

Kitchen wastes recycle to compost

Old newspapers mulched

Manures used biogas or to improve soil

Household wastewater flows to the garden

Rain and runoff harvested

Green manures are turned into the earth

Leaves are raked around trees as mulch

5Rs – resist, reduce, reuse, recycle, recover

Catch, store, and use everything before it has degraded to its lowest energy use and so is lost to entropy.

PDC SOMO LA 1.2 KANUNI ZA KUENDESHA BAISKELI WA NISHATI

Komesha mtiririko wa virutubisho na nishati nje ya tovuti, na badala yake ugeuze kuwa mizunguko.

Kila tukio la mzunguko huongeza fursa ya mavuno. Kuongeza baiskeli ni kuongeza mavuno. Saidia badala ya kuzuia mizunguko ya asili ya biogeochemical (kaboni, nitrojeni, potasiamu ya fosforasi, kihaidrolojia, n.k.)

Tumia nishati inayoingia (jua, maji, upepo, samadi, n.k.) kama matumizi yake ya juu iwezekanavyo, na kisha ni ya juu zaidi, na kadhalika.

MFANO

Mabwawa na swales kukusanya na kushikilia maji

Taka za jikoni hurejeshwa kuwa mboji

Magazeti ya zamani yamechapishwa

Mbolea zilitumia biogas au kuboresha udongo

Maji machafu ya kaya hutiririka hadi kwenye bustani

Mvua na maji yanayotiririka yamevunwa

Mbolea za kijani hubadilishwa kuwa ardhi

Majani hukatwa kuzunguka miti kama matandazo

5Rs - kupinga, kupunguza, kutumia tena, kuchakata tena, kupona

Pata, hifadhi na utumie kila kitu kabla hakijaharibika hadi matumizi yake ya chini ya nishati na hivyo kupotea kwa entropy.

KAMATA NA UHIFADHI NISHATI

Kwa kutengeneza mifumo inayokusanya rasilimali zinapokuwa nyingi, tunaweza kuzitumia wakati wa mahitaji.
