PDC LESSON 1.9 PRINCIPLES OF DIVERSITY

Include as much diversity in a cultivated ecosystem as it can maintain itself, then let it simplify or complicate further if that is its nature.

NATURE

Ecosystems with high diversity tend to be able to recover from disturbance and restore balance in their processes of material cycling and energy flows; in ecosystems with low diversity, disturbance can more easily cause permanent shifts in function, resulting in the loss of resources from the ecosystem and changes in its species makeup.

BENEFITS

With higher diversity there is:

greater micro-habitat differentiation.

increased range of micro-climates.

increased opportunities for coexistence and beneficial “connections” between species.

greater support for predatory insects,

greater resource use, and insurance against localised crop failure.

In the garden increase your diversity through heritage seed varieties, and the inclusion of plants for a range of functions.

Embracing diversity in all things can lead to a more multi-functional and stable lifestyle.

PDC SOMO LA 1.9 KANUNI ZA UTOFAUTI

Jumuisha anuwai nyingi katika mfumo wa ikolojia uliopandwa kadiri inavyoweza kujidumisha, basi iruhusu irahisishe au iwe ngumu zaidi ikiwa hiyo ndio asili yake.

ASILI

Mifumo ya ikolojia yenye utofauti mkubwa huwa na uwezo wa kupata nafuu kutokana na usumbufu na kurejesha usawa katika michakato yao ya baiskeli ya nyenzo na mtiririko wa nishati; katika mifumo ikolojia yenye utofauti mdogo, usumbufu unaweza kwa urahisi zaidi kusababisha mabadiliko ya kudumu katika utendaji kazi, na kusababisha upotevu wa rasilimali kutoka kwa mfumo ikolojia na mabadiliko katika muundo wa spishi zake.

FAIDA

Pamoja na utofauti wa juu kuna:

utofautishaji mkubwa wa makazi madogo.

kuongezeka kwa anuwai ya hali ya hewa ndogo.

kuongezeka kwa fursa za kuishi pamoja na "miunganisho" yenye manufaa kati ya spishi.

msaada mkubwa kwa wadudu waharibifu,

matumizi makubwa ya rasilimali, na bima dhidi ya kushindwa kwa mazao yaliyojanibishwa.

Katika bustani ongeza utofauti wako kupitia aina za mbegu za urithi, na ujumuishaji wa mimea kwa anuwai ya kazi.

Kukumbatia utofauti katika mambo yote kunaweza kusababisha maisha yenye kazi nyingi na thabiti.

TUMIA MIFUMO MIDOGO NA LESENI

Mifumo midogo na polepole ni rahisi kudumisha kama mikubwa, kutumia vyema rasilimali za ndani, na kutoa matokeo endelevu zaidi.
