La necesidad de incentivos financieros para fomentar los sistemas agroforestales como islas de biodiversidad en paisajes degradados

Agroforestry is one of the most conspicuous land use systems across landscapes and agro ecological zones in Africa. Some of the components of Agroforestry systems are; home garden agroforestry, alley cropping, forest farming, wind break, river banks, park land, crop land trees and buffer zones agroforestry practices. Climate change impacts by complex weather-related phenomena have threatened agricultural and forest ecosystems and the livelihood of agricultural and local communities. Agroforestry has an important role in climate change adaptation through diversified land-use practices, sustainable livelihoods, sources of income, enhanced forest and agricultural productivity and reduced weather-related production losses, which enhance resilience against climate impacts. Like few other land use options, agroforestry has real potential to contribute to food security, climate change mitigation and adaptation, while preserving and strengthening the environmental resource base of Africa’s rural landscapes. It has a key role to play in landscape-scale mitigation schemes under the REDD+or AFOLU (Agriculture, Forestry and other land uses) concepts. Home garden agroforestry system indicates that adaptation and mitigation to climate change will largely depend on the increased resilience of both agroforestry systems and of local management capacity. Despite less attention has been given to tree based land use option, agroforestry has played a major role in reducing household vulnerability to shocking. Smallholder farmers have already started mainstreaming tree based land use system as resilience to social needs because the poor are more exposed to change; Agroforestry is one of best risk aversion option to make them move out of food insecurity. Generally, agroforestry systems readily bundle both mitigation and adaptation strategies and provide several pathways to securing food security for poor farmers, while contributing to climate change mitigation. Agroforestry should attract more attention in global agendas on climate adaptation and mitigation because of its positive social and environmental impacts.

Abstract: Agroforestry systems are believed to provide several ecosystem services; however, until recently evidence in the agroforestry literature supporting these perceived benefits has been lacking. This paper aimed to provide empirical information on the role of agroforestry in ecosystem maintenance and climate change adaptation and mitigation provided by agroforestry. Agroforestry has played a greater role in the maintenance of the ecosystem and mitigation of CO2 than monocropping and open cereal-based agriculture but less than natural forest. The three components of agroforestry are important for biodiversity conservation, CO2 sequestration, and climate change adaptation. CO2 sequestration through above and ground biomass, offsetting CO2 emission from deforestation and microclimate modification are major climate change mitigation effects. Provision of numerous ecosystem services such as food, fodder, and fuel wood, income source, and enhancing soil productivity help the community to sustain changing climate effects. Hence, considerable attention needs to be given to agroforestry to contribute considerable benefit to the maintenance of the ecosystem, and climate change mitigation and adaptation next to a forest.

This review examines the role of agroforestry systems in Ethiopia, focusing on their contributions to soil health improvement and carbon sequestration for climate change mitigation. The study utilized a meta-analysis approach, gathering data from prominent databases such as Scopus, Web of Science, PubMed, Google Scholar, and AGRICOLA. Keywords related to agroforestry and climate change mitigation were used to screen relevant studies. A total of 54 studies were included after systematic screening and full-text review based on eligibility criteria. The analysis employed both descriptive and quantitative synthesis to evaluate the effectiveness of agroforestry in improving soil fertility, carbon sequestration, and resilience to climate change. The results showed that agroforestry systems, including parkland and coffee-based systems enhance soil organic carbon (SOC) and increase soil fertility. Coffee-based agroforestry systems, for instance, sequester up to 7.2 tons of CO₂ per hectare annually, while home-gardens in southern Ethiopia store up to 150 tons of carbon per hectare. The integration of drought-resistant species further improves soil moisture retention and boosts productivity in arid areas. In addition to environmental benefits, agroforestry systems also support food security and economic resilience by diversifying income sources and stabilizing yields in the face of climate variability. The findings underscore the significant potential of agroforestry systems in enhancing soil health, sequestering carbon, and contributing to climate change adaptation and mitigation in Ethiopia.

Ocean conservation boosts climate change mitigation and adaptation

The synergistic effects of agroforestry on carbon sequestration and climate adaptation strategies, emphasizing its role in sustainable agriculture and land management. Agroforestry plays a important role in climate change mitigation and adaptation by integrating trees, crops, and livestock to enhance carbon sequestration, improve soil health, and increase ecosystem resilience. A systematic analysis of recent literature from journals and policy reports to evaluate the impact of agroforestry on carbon sequestration and climate adaptation. Agroforestry systems, including agrisilviculture, silvopasture, and agrosilvopastoral practices, contribute significantly to carbon sequestration through aboveground biomass accumulation, root carbon storage, and soil organic matter enhancement. The ability of agroforestry to mitigate climatic extremes, such as droughts, extreme temperatures, and soil erosion, underscores its importance in enhancing agricultural resilience. The adoption of agroforestry-based carbon sequestration strategies is supported by international climate policies, including the Paris Agreement, REDD+, and Sustainable Development Goals (SDGs), while financial mechanisms such as carbon trading and payment for ecosystem services (PES) offer incentives for farmers. Despite its benefits, agroforestry faces barriers such as policy fragmentation, high implementation costs, and the need for standardized carbon measurement methodologies. Technological advancements, including genetic improvement of tree species, precision farming, and climate-smart agroforestry strategies, present opportunities to enhance its effectiveness. Future research should focus on multidisciplinary approaches integrating remote sensing, soil science, and socioeconomic analysis to optimize agroforestry’s carbon sequestration potential. Government policies should prioritize financial support, capacity building, and land tenure security to scale agroforestry adoption. Strengthening institutional frameworks and leveraging climate finance mechanisms will be essential for mainstreaming agroforestry into national and global climate action plans. Expanding research on carbon sequestration measurement and incentivizing farmer participation through payment for ecosystem services are key to scaling agroforestry solutions. A multi-disciplinary approach combining ecological, economic, and policy innovations is essential to unlocking the full potential of agroforestry in combating climate change and ensuring long-term sustainability.

Agroforestry is seen as a land management technique that can address many of the issues faced by smallholder farmers, such as climate change adaptation and climate change mitigation. Agroforestry helps farmers adapt to extreme weather events, create resilient microclimates for crops and livestock across regions, and help combat climate change. An important role of agroforestry in tackling climate change may be to reduce CO2 emissions by actively sequestering carbon from the atmosphere. Soil stores the largest carbon stock (77%–92%) in agroforestry systems, with trees, herbaceous plants, and deciduous trees absorbing 7%–22% and 1%, respectively. Smallholder farmers in developing countries not only build resilient agroecological systems that actively absorb carbon, but also revert to more natural production systems that provide better ecological and social functions. By doing so, we can prevent climate change. Agroforestry not only reduces greenhouse gas emissions and improves the resilience of agricultural landscapes, but also can contributes to climate change mitigation and adaptation by promoting species migration to more favorable conditions and carbon sequestration. Climate projections could see production declines in much of sub-Saharan Africa, exacerbating food insecurity among citizens.

Conventional agriculture is the dominant contributor to negative environmental impacts such as the growth in global greenhouse gas (GHG) emissions, and the challenges are likely to increase with the increasing global food demand as well as the agricultural expansion. Agroforestry is a sustainable management practice with strong potential to provide ecosystem services and environmental benefits through increasing carbon sequestration, nutrient availability, water use efficiency and biodiversity, and reducing soil erosion and nitrogen losses. Therefore, the establishment of agroforestry practices offers an opportunity to reduce GHG emissions. Previous studies have showed the effects of agroforestry on soil nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) fluxes in many parts of the world. In temperate Europe, the information on the GHG mitigation potential of agroforestry compared to cropland monoculture is still unclear. The present thesis consists of two studies, which was designed to explore whether the conversion of cropland monoculture to agroforestry systems reduces trace gases N2O, CO2, and CH4 emissions from the soil. The study was carried out at three sites varied with soil types in Germany. Each site had adjacent alley cropping agroforestry and cropland monoculture systems and the trees in agroforestry system were planted 1 to 11 years prior to this research. We measured soil N2O, CO2, and CH4 fluxes monthly using vented static chambers at the three sites from March 2018 to January 2020. On each day of gas sampling, soil temperature, water-filled pore space and extractable mineral nitrogen (N) were measured in the top 5 cm. The objective of our first study was to quantify the spatial-temporal dynamics of soil N2O fluxes from cropland agroforestry and monoculture systems, following different crop rotations and fertilization rates. The pattern of soil N2O fluxes were predominantly controlled by soil mineral N in both agroforestry and monoculture systems. The positive relationship between water-filled pore space with soil N2O fluxes during the cropping seasons, indicating soil moisture acts as a limiting factor under N-sufficient conditions. The entire agroforestry systems tended to reduce soil N2O emissions by 9% to 56% compared to monocultures, during the corn phase of the rotation that had typically high fertilization rates. The lowest soil N2O emissions in the unfertilized tree rows (occupied 20% of the agroforestry area) represent a potential for mitigating N2O emissions from croplands. The objective of our second study was to investigate the changes in soil CO2 and CH4 fluxes after conversion from cropland monoculture to alley cropping agroforestry systems. Our results showed that seasonal variations of soil CO2 and CH4 fluxes were strongly regulated by soil temperature and moisture, and the spatial variations were mainly controlled by texture. The establishment of agroforestry systems had no effect on reducing soil CO2 emissions, possibly because there was no significant difference in soil temperature between management systems. Annual soil CH4 uptake in the agroforestry systems was increased by up to 300% compared to monocultures, which may be related to the regulation of trees on soil moisture in agroforestry systems. The present research provides the first insight into the systematic comparison of soil N2O, CO2 and CH4 fluxes from cropland agroforestry and monoculture systems, and it provides a unique dataset for estimating the net balance of carbon emissions after conversion of cropland monoculture to alley cropping agroforestry system in temperate regions. Although soil CO2 emissions showed no differences between management systems, the total annual soil emissions of non-CO2 GHG from agroforestry systems were reduced by 0.22 Mg CO2 eq ha-1 compared to the monocultures. Considering the driving function of soil moisture and mineral N on soil GHG fluxes from cropland agroforestry and monoculture systems, our findings suggest that improved system management (e.g. optimal adjustments of the areal coverages between tree and crop rows) and optimized fertilizer input will enhance the potential of cropland agroforestry for mitigating N2O emissions and increasing CH4 uptake and C sequestration in the long run.


 East Kalimantan Province is very vulnerable to climate change, so it needs policies and strategies in managing climate change impacts through adaptation and mitigation actions. So it is necessary to stipulate local regulations on climate change adaptation and mitigation. Management of climate change in East Kalimantan is one of the local government's efforts in providing guarantees to the community to get a quality living environment. The purpose of this community service activity is to provide understanding to residents regarding East Kalimantan Regional Regulation No. 7 of 2019 concerning climate change adaptation and mitigation. The method of implementing this community service activity is in the form of counseling and discussion of East Kalimantan Regional Regulation No. 7 of 2019 concerning climate change adaptation and mitigation.
 
 Based on the results of community service activities related to the extension of East Kalimantan Regional Regulation No. 7 of 2019 regarding climate change adaptation and mitigation, it was concluded that many people still do not know about the regional regulation. Efforts to mitigate and adapt to climate change are not only the responsibility of the Government, but also the responsibility of the DPR. The DPR's climate change mitigation and adaptation efforts can be carried out through the implementation of its three functions, namely the budget function, the supervisory function, and the legislative function. Every stakeholder, including the community, must mitigate and adapt to climate change, because adaptation and mitigation is the key to addressing climate change, which is the key to reducing greenhouse gas emissions and increasing carbon stocks to reduce the impact of climate change. The active role of the regional government in formulating policies related to climate change is a must, the policy is expected to be a direction for stakeholders in East Kalimantan.

Climate change refers to future fluctuations of temperature, precipitation, wind and alternative components of Earth’s climate system. Global climate change within the style of higher temperature, reduced downfall, and inflated downfall variability reduces crop yield and threatens food security in low financial gain and agriculture primarily based economies. Ethiopia is one of the most vulnerable countries experiencing drought and floods as a result of climate variability and change. The general objective of this review is to administer and summary on adaptation and mitigation measures initiative in Ethiopia in response to climate change. In Ethiopia the foremost vulnerable sectors to global climate change and variability are agriculture, road, water energy and health. Thus Mitigation and adaptation measures pursued to effectively address climate change. In Ethiopian farming communities have important indigenous knowledge, skills and technologies that are essential for tackling hazardous environmental conditions including climate variability and change. They employ a number of short- and long-term climate change mitigation and adaptation measures to cope with and overcome the impacts of climate variability and change. On the opposite hand, Ethiopia has shown both conservation and policy responses to combat climate change. Protected area systems, a forestation and reforestation programmes, renewable energy sources and energy efficiency, ecological agriculture, flexible livestock production, agro forestry systems, harvesting and climate change education, are all feasible strategies for mitigating and adapting climate change.

Agroforestry systems (AFS) are becoming increasingly relevant due to their multiple roles and services: biodiversity conservation, adaptation and mitigation of climate change, restoration of degraded ecosystems, and tools for rural development. This chapter summarizes advances in agroforestry research and practice and raises questions as to the effectiveness of AFS to solve the development and environmental challenges the world presents us today. The initial emphasis of the research in AFS was on showing how AFS could be a viable productive alternative, focusing on AFS design, multipurpose tree species and their functions and products, and financial evaluations. Later, responding to increasing environmental and rural development issues worldwide, research turned to the challenges of alleviating poverty and improving food security. In the last decade emphasis has been on the role that AFS can play in adaptation to climate change, and mitigation of greenhouse gas emissions through fixation of atmospheric carbon. Currently AFS are expected to achieve a compromise among productive and environmental functions. Apparently, AFS can play a significant role in rural development even in the most challenging socioeconomic and ecological conditions. Considerable funding is spent on projects to enhance productivity and sustainability of smallholders agroforestry. These projects and programs face many questions and challenges related to the integration of traditional knowledge to promote the most suitable systems for each situation; access to markets for AFS products, and scaling up of successful AFS. This book gathers fresh and novel contributions to provide alternative and sometimes departing insights into these pressing questions.

Forests, when sustainably managed with the participation of local communities, can have a central role in climate change mitigation and adaptation. One of the most important forest ecosystem services is carbon sink from atmosphere during its early growing stage as compared to the late stage. And this has been used as a climate change adaptation strategy locally and mitigation mechanism globally to curb the multi-sectorial problems of climate change. But this depends on effective participation of the households on forest ecosystem service provision (FESP) activities. Therefore, this paper presents the socio-economic determinants of the local household participation on FESP using 157 sampled households with econometric and descriptive analysis. The result shows that FESP negatively determined by gender difference, state of agro-ecology/agro-ecosystem, level of annual net benefit, distance to forest site and other source of income while attending on community meeting and literacy level increased level of participation thereby increasing annual return of individual local households. Furthermore, the highest returns from FESP goes to the rich households and the poor earn less for their fair share of labor though highest costs covered by the rich. Therefore, all users and services providers ought to facilitate inspiring environments to gear the way forward for climate change adaptation and mitigation mechanisms in the future.

Climate is one of the most important factors that influence and determine the behavior, abundance and distribution of species, as well as having a strong influence on the ecology of habitats and ecosystems structure. Changes in the behavior, abundance and distribution of species are linked to climate. Diversity and plant species are highly interlinked and the relationship between biodiversity and climate change should be explored from several perspectives. This variety provides the building blocks to adapt to changing environmental conditions which are caused due to climate change. Conserved habitats can remove carbon dioxide from the atmosphere, thus helping to address climate change by storing carbon in the plant biomass. Climate is one of the major limiting factors which determine the survival and growth of plants. The conservation and restoration of biodiversity and ecosystem services can play a key role in helping societies to adapt to climate change. Biodiversity is affected by climate change, but biodiversity, through the ecosystem services and function it supports, also makes an important contribution to both climate-change mitigation and adaptation. Maintenance of agro-biodiversity and carbon sequestration through the process of photosynthesis is the two important and complementary environmental services of agro-ecosystems. Climate change affects biodiversity and one of the causes of biodiversity loss. At the same time climate change will accelerate further if biodiversity and ecosystems are not effectively protected. Generally due to the variation of genetic makeup within pants, different plant species diversity plays a great role in climate change adaption and mitigation process.

Can agroforestry systems enhance biodiversity and ecosystem service provision in agricultural landscapes? A meta-analysis for the Brazilian Atlantic Forest

There are worldwide approximately 4.3 million coffee (Coffea arabica) producing smallholders generating a large share of tropical developing countries’ gross domestic product, notably in Central America. Their livelihoods and coffee production are facing major challenges due to projected climate change, requiring adaptation decisions that may range from changes in management practices to changes in crops or migration. Since management practices such as shade use and reforestation influence both climate vulnerability and carbon stocks in coffee, there may be synergies between climate change adaptation and mitigation that could make it advantageous to jointly pursue both objectives. In some cases, carbon accounting for mitigation actions might even be used to incentivize and subsidize adaptation actions. To assess potential synergies between climate change mitigation and adaptation in smallholder coffee production systems, we quantified (i) the potential of changes in coffee production and processing practices as well as other livelihood activities to reduce net greenhouse gas emissions, (ii) coffee farmers’ climate change vulnerability and need for adaptation, including the possibility of carbon markets subsidizing adaptation. We worked with smallholder organic coffee farmers in Northern Nicaragua, using workshops, interviews, farm visits and the Cool Farm Tool software to calculate greenhouse gas balances of coffee farms. From the 12 activities found to be relevant for adaptation, two showed strong and five showed modest synergies with mitigation. Afforestation of degraded areas with coffee agroforestry systems and boundary tree plantings resulted in the highest synergies between adaptation and mitigation. Financing possibilities for joint adaptation-mitigation activities could arise through carbon offsetting, carbon insetting, and carbon footprint reductions. Non-monetary benefits such as technical assistance and capacity building could be effective in promoting such synergies at low transaction costs.
