Outcomes for Rio+20
SOIL IN THE DECISION MAKING PROCESSES, THE
EXPERIENCE OF URUGUAY

URUGUAY
Total land area: 17 millon ha
77% pasture and grassland basis of
livestock production
11 millon bovine
7,7 millon ovine
1,25 millon ha rainfeed agriculture
200 miles ha irrigated rice
1 millon ha planted forestry
Average annual rainfall 1200mm

3.356.584 habitants
Current scenario
The Uruguayan economy is in the process of
structural transformation:
Increased external openness ratio
Increased specialization profile agricultural
/ agribusiness (intensive NR)
Increased Foreign Direct Investment

Current scenario
Decreased area of pasture
Agricultural crops are the economic backbone of
the current situation
The same use and management of soils is
performed in many cases, in soils with different use
capacities
Climate Change
Increased vulnerability of agroecosystems
Low sustainability
Increased risk
Current erosion
Degradation risk

The MGAP strategy aims to…
 Further develop agricultural export with
higher added value includin family agriculture
 Policies for sustainable use of NR and
adaptation to climate change
Through …
The General Directorate of Renewable
Natural Resources is responsible for
promoting, regulate and control the use
and sustainable management of natural
resources
relevant
to
agricultural
production and value chains.
Legislation …
Aims the resposable and sustainable agricultural
development in a frame of large and full respect
for the environment.
Obligation of propietary and holders of lands

Agricultural activity is not discretionary of
farmers on land use technical aspects

There is a specific regulation for the act to grow
Article 5: Decree 405/2008
Shall require a plan for responsible soil use and
management considering:
The soils
Tolerable erosion
Projected production systems
Crop secuencies
Management practices
Plan of soil use and management
This plan provides guidelines on the use and soil
management of an establishement in order to
comply with th standars established in the regulation
of Law Nº 15.239.
The plan´s main objective is to achieve sustainable
production systems with good use, maintenance and
reclamation of soils.
Plan of soil use and management
Plans must be submitted with an agronomy
signature
Land owner commitment

Tools
► Universal
Soil Loss Equation (Wischmeier, W. H.;
Smith, D. D. 1978)
Revised Universal Soil Loss Equation (Renard, K.G.
et al 1997)
► More
than 35 years of national research in
validation and adaptation of the model

Pure agricultural crop rotation: 65%
Crop pasture rotation: 35%
Considerations

Confirm objetives and tools

It was considered appropiate and relevant to
extend the pilot phase 1 more year to get covered
with preparedness activities.

Mantain the requirements for agreed locations
(Basine of Laguna del Sauce and Rocha Lagoon
protected Area and investement law: clean
production)

Further organic carbon
