Theme:

Nature-based Solutions

Nature-based Solutions (NbS) is an umbrella concept concerning all actions and approaches related to the management of ecosystems and biodiversity to address both global environmental and societal challenges, including climate change. The potential of NbS is gaining prominence among global policy arenas because of its cost-effectiveness and ability to deliver multiple co-benefits for nature and people. Broadly speaking, NbS offer the opportunity to address three of the most critical challenges of the Anthropocene:

  1. tackle climate change through adaptation and mitigation,
  2. halt biodiversity loss, and
  3. contribute to human health and well-being.

The concept of NbS integrates previously established nature-based approaches such as:

  • ecosystem-based adaptation (EbA),
  • eco-disaster risk reduction,
  • green infrastructure and
  • natural climate solutions.

Central to the NbS concept is the premise that healthy and resilient ecosystems produce a diverse range of services on which human well-being depends. The application of NbS involves a range of actions that can use, manage, or be inspired by nature, including preserving and restoring natural and modified ecosystems, creating novel ecosystems, building and integrating green and blue infrastructure, and adopting multiple ecosystem-based approaches in both rural and urban landscapes.

Building on previous concepts such as EbA, the NbS approach has motivated promising undertakings around the world.  At present, many NBS projects show potential cost-effectiveness compared to hard engineered and more techno-centric solutions - partly given to the multiple benefits they generate. However, there is a lack of systematic collection and review of scientific evidence to assess their actual effectiveness. The Nature-based Solutions Initiative (NBSI) is proactively gathering scientific evidence to inform the development and implementation of NbS-related interdisciplinary research, policy and practice. As of 2020, about 65% (250 out of 384) of the NBS-related academic publications reviewed by the NSBI were linked to climate change adaptation. This theme will become a new repository for NbS case studies to learn from.

Ecosystem-based adaptation for smallholder subsistence and coffee farming communities in Central America

Climate models indicate that Central America will likely experience warmer and drier seasons and increases in the frequency of extreme weather events as a result of climate change. Smallholder farmers are likely to be particularly vulnerable to these expected changes due to their high dependence on agriculture for their livelihoods and their limited resources and capacity to cope with shocks. There is therefore an urgent need to identify strategies that help smallholder farmers adapt to climate change. Improving the productivity and resiliency of smallholder farming systems is also critical for alleviating poverty and achieving food security.

Draft Principles and Guidelines for Integrating Ecosystem-Based Approaches to Adaptation in Project and Policy Design

Ecosystem-based approaches to reduce social vulnerability are a promising option for sustainable and efficient adaptation to climate change. Ecosystem based Adaptation (EbA) is part of overall adaptation, and takes into account multiple social, economic and cultural co-benefits for local communities. EbA encompasses adaptation policies and measures that take into account the role of ecosystem services in reducing societal vulnerability, through multi-sectoral and multi-level approaches.

Equitable Payments for Watershed Services (EPWS) Project in Tanzania

Equitable Payments for Wateshed Services (EPWS) is part of a broader concept of Payments for Environmental/Ecosystem Services (PES) with the underlying principle of which the beneficiaries (which are recognised as buyers) of environmental/ecosystem services should compensate those who provide or play a role to guarantee continuous flow of such services (who are recognised as sellers of the services). The EPWS program in Tanzania which is implemented jointly by CARE International and WWF Country Office stands to ensure a sustainable flow of watershed services to beneficiaries into the future via a mechanism that promotes articulation of conservation practices in catchment areas which in turn alleviate poverty to land managers.
