Title: Local ecological knowledge in natural resource management
1Local ecological knowledge in natural resource
management

Alegre and Fergus Sinclair
Bridging Scales and Epistemologies
Conference, 17-20 March 2004, Alexandria, Egypt
2Rationale
- Rural people depend on natural resources for
their livelihood - long term use depends on their ability to manage
- farmers are heterogeneous in terms of their
management ability, objectives, dependence, local
context, experience and observations - In natural science, the emphasis is on practical
explanatory and predictive knowledge
3Knowledge
an output of learning, reasoning and perception
and a basis for predictions of future events it
is peoples understanding and interpretation
based on some explainable logic of supposedly
general validity.
4Local Ecological Knowledge
- local peoples knowledge about elements and about
processes and inter-relationship between these
elements of their agro-ecosystem.

6Methodology
Knowledge-based systems approach
- Articulation and representation of local
ecological knowledge to effectively incorporate
local ecological knowledge and local perspective
in RD programs.
7Reported study Indonesia
- Sumberjaya, South Sumatra
- coffee based sun, shade and multistrata system
on slopes - disputed land
- mostly local people
- long farming experience
8Reported study Peru
- Pucallpa Shipibo Conibo community
- fishing, hunting and gathering fruits and
medicinal plants - farming relatively new
- annual flooding (2-3 months)
9Results Indonesia
- Farmer innovations (terraces, vegetation strips,
furrows and compost pits, multi-storey system) - turbidity in paddy fields nutrient source for
plants but water flow must be regulated - landscape scale riverside vegetation (roots)
for watershed functions - Knowledge of other factors exist but not always
practised - Key reasons
- resource (especially time and labour)
constraints - individual efforts not very effective
- insecure land tenure uncertainty
10Explanatory knowledge
11Results Peru
- Soil fertility related to post-flooding condition
of soils - dark non-clayey property and organic
content (indicated by crop performance) - Knowledge about poor fertility indicator plants
e.g. shuashui (?), arrocillo (Rottboellia
exaltata), gramalote (Brachiaria mutica) - Flood tolerant and flood susceptible fruits but
much contradiction among the people - Local ecological knowledge about soil resources
less sophisticated - Knowledge about fishing and hunting richer?
12Research indicate that LEK
- has explanatory aspects, with a logical structure
comparable to scientific understanding - comes largely from experience
- holistic and un-disciplined
- notions of description, classification and
fertility of soils lacalized - explanatory knowledge and underlying principles
can be generalized (regularity across similar
agroecosystems) - knowledge may not always translate into action
other constraints - LEK is not opaque - can be articulated and
recorded through structured discussions with
local people
13LEK research in NRM
- focused development imperatives
- useful for three aspects
- Building on local practice
- Recognizing sophistication of local knowledge
(and terminology) for effective communication - Realising its limitations windows for
improvement
