Systems and integration System:
Limited part of reality Interacting components Delineation
Integration: What does the research result mean at the target system level? What is the pertinent management unit? farm / household

Means- vs. goal-oriented Means-oriented:
Evaluation of quality of measures and techniques at field and farm level Often labeled “sustainable” a-priori
Goal-oriented: Comparison of the productive, environmental and social performance Using a set of explicit goals, made operational through indicators (MF) Different spatial and temporal scales and organization levels
Focus on the outcomes (goals), that can be reached by different system configurations and implemented measures and techniques

Trade-offs at system level When improving the system for one goal, an other goal can be
compromised (ex. F1 = profit, F2 = soil quality – i.r.t. livestock) Evaluate trade-offs in terms of goals at the target system level Often there are multiple ways to reconfigure to reach goals

Ex. Goals for HHs (1): Labor/leisure time
Farm labor balance
Gendered labor distribution
Household labor allocation

Ex. Goals for HHs (2): Budget
On and off-farm income
Expenditures, food and other
Available free HH budget

Beyond trade-offs: integrative solutions Try to identify solutions to problems that overcome trade-offs and
avoid compromise Integrative solutions require insight into whole-system responses to
different forms of use and an overview of services provided
Example crop residue use: Allocations: as mulch, feed, firewood, building material Goals: improve soil fertility, feed animals, cooking, heating, building Solutions…

Dealing with diversity Farms and households differ in:
Size and structure (farm, HH) Development stage (HH) Goals and constraints (HH)
Distributions: overview of the ranges and variation Typologies: grouping of diverse population into similar types
Farms/HHs with different characteristics need different solutions
![Page 15: Integrated systems research for farms and livelihoods in Africa RISING phase II](https://reader035.vdocuments.net/reader035/viewer/2022062522/588324b41a28abe2758b5e7f/html5/thumbnails/15.jpg)
Trajectories of change
How to attain goals in a sequence of changes?
Different pathways (sequences of solutions) for different farm/HH types

Conclusions Evaluate research outcomes in the context of the target system
Focus on the goals of farms and households, how to attain these
Explore the system-level trade-offs, look for integrative solutions
Identify the trajectory (-ies) to follow to reach the ultimate goals
Accommodate diversity in farm and household structure and goals
Embrace a portfolio-approach combining multiple methods

Ex. Farm configuration

Ex. Goals for farms (1): Nutrient yield
Yield is expressed as the number of people (consumer units) that can be sufficiently nourished for a given nutrient

Ex. Goals for farms (2): Operating profit
![Page 21: Integrated systems research for farms and livelihoods in Africa RISING phase II](https://reader035.vdocuments.net/reader035/viewer/2022062522/588324b41a28abe2758b5e7f/html5/thumbnails/21.jpg)
Sustainable by design (example boundary object)
Is it good for the environment?
Is it profitable?
Is the farm productive without causing degradation?
Are farmers safe in making and using their products?
Do farm operations contribute to environmental quality?
Do all HH members have access to resources?
Are people treated the same?
Do farmers and workers get a living wage?
Do men and women paid the same for the same job?
