ReGreening Initiatives
ReGreening Initiatives
(RGI) is used here to cover all interventions
which increase tree density and cover in the landscape, in farms, rangelands,
wastelands and degraded forests.
GPI2050 Action(s)
Land degradation leads to a decline in crop yields, food availability, soil fertility, carbon
sequestration capacity, wood production, and groundwater recharge, with significant social and
economic costs. The Organisation address these emerging issues identified across Kenya by
implementing an ecosystem-based adaptation approach to building resilience; bringing together
significant policy expertise, scientific expertise and on-the-ground investments to build
knowledge and understanding of the climate risks and to enable sustainable, climate-resilient
transformation at scale. The organization combines indigenous knowledge with scientifically
robust approaches to build on and scale-up existing successful Re-Greening projects through
locally appropriate interventions. To varying degrees, all of these approaches increase crop
productivity, reliability and resilience; increase the direct production of food, fuel, fibre and
income from the products; enhance carbon storage and biodiversity, both above-ground and
below-ground, enhancing rain-use-efficiency.
The Organisation employs the following models and approaches:
1. Ecosystem-Based Adaptation (EBA)
Uses biodiversity and ecosystem services as
part of an overall adaptation strategy to help households and communities adapt and
respond to the negative effects of climate change at local, national and regional
levels.
2. Regenerative Agroforestry
An ecosystem-based adaptation practice that
integrates trees and shrubs into agricultural and livestock systems. Agroforestry
systems involve a wide range of trees that are protected, regenerated, planted or
managed with annual crops, livestock, wildlife and humans. This practice provides
beneficial products and services and increase the resilience of communities,
assisting them to adapt to climate change at an extremely low cost.
3. Re-Greening Initiatives and Approaches
Sub-set of agroforestry which
emphasizes the deliberate integration of trees and shrubs into cropping systems and
pastoral land by planting or managed natural regeneration, which complement and
enhance the sustainability, productivity and resilience of those systems through
biological interactions. These practices can be easily and inexpensively adopted by
rural households. They focus on low-cost, rapid and proven effective technologies to
maintain vegetative soil cover, bolster nutrient supply through nitrogen fixation and
nutrient cycling, generate greater quantities of organic matter in soil surface residues
and improve soil structure and water infiltration.
4. Re-greening
The process in which farmers protect and manage trees that naturally
regenerate on their land, rather than cut them down. Regenerated trees and shrubs
help restore degraded lands and provide many benefits – from increased crop yields,
recharging groundwater, providing fodder and firewood, and storing carbon.
Agroforestry, where on-farm trees are managed with crops and/or animal production
systems, is a cost-effective and "climate-smart" way to intensify and diversify
agriculture. Innovative farmers have also developed water harvesting techniques and
other improved practices that restore the productivity of degraded lands and
contribute to landscape level re-greening.
5. FMNR (Farmer Managed Natural Regeneration
The protection and management
by pruning of naturally-regenerating trees and shrubs, from roots and seeds that are
already present in the soil has proven to be exceedingly effective as a very low-cost
way to restore degraded land. FMNR refers specifically to the natural regeneration
and management (pruning) of trees.
This can be used effectively in farmland (Farmer Managed Natural Regeneration or
FMNR), rangeland, wasteland and degraded forests. Taking advantage of the large
root system of previously established trees, growth is very fast and mortality
extremely low. Emphasis is on the management by the landowner or community.
Benefits include restoration of trees, soil health and fertility, water infiltration and
retention in the soil. The survival rate of regenerating flora is far higher than that of
planted seedlings, and they generally require less maintenance and fewer (often
zero) inputs.
6. Natural Resource-Based Value Chain Development Integrated With Improved Access To Finance
Household adoption of Re-Greening practices are incentivized
through local ecosystem-based value chain development which will in turn increase
income and economic benefits to small-scale farmers. The Programme will focus on
sustainability, reliability and productivity of farming systems at the household level,
while building the capacity and function of CBO's, farmers’ associations and groups
to ensure improved coordination and more efficient market access. This will include
bulking of produce, improved quality control, handling and storage, and reduced
transaction costs. Opportunities for investments and profitable small-scale value
chains in this Programme exist in the inclusion of timber or fuel wood trees, either
intercropped in cropping systems, or through farm woodlots with sequential
agroforestry; fruit and nut trees such as cashew, shea, mango, moringa and baobab;
resins such as gum Arabica; and sylvo-pastoralism, which combine trees and
livestock. Whilst promoting tree-based value chains, the trees and resultant carbon
sequestration will be treated as a future income source through, where feasible,
engagement with carbon markets.
7. Soil and Water Conservation:
Soil loss is one of the major threats to agricultural
development in several of the included Counties. Loss of soil from farmlands has
resulted in declining crop yields and hinders overall economic development. Where
fertile topsoil is lost, it disproportionality reduces soil nutrients and carrying capacity,
requiring (where possible) increased expenditure on fertilizers, which reduces
financial viability and negatively impacts the ecosystem. It also leads to a reduction
in the cultivable soil depth. Besides the negative impact on agriculture, soil loss also
affects surface water resources through reduced water quality and quantity,
increased floods, and siltation of rivers. In some highly degraded areas, Re Greening
practices alone are not enough to restore land and meet the multiple needs of the
farmers and ecosystems, so complimentary approaches have been integrated into
the Programme. Re Greening practices will be supported through low cost on-farm
soil and water conservation practices, including increasing soil organic matter,
improving water retention capacity and applying water harvesting techniques. These
soil and water conservation approaches will serve to capture rainfall that would
otherwise run off the fields causing erosion, and increase soil water availability and
fertility, thereby also increasing crop yields. The combination of these activities with
EGP and eco-disaster risk reduction will serve to reduce risk, enhance biodiversity
and increase the diversity of available food products at the household level.
