Africa RISING Project: Local knowledge of farmers on constraints and opportunities to sustainable intensification of tree-crop-livestock mixed systems in Lemo Woreda, Southern Nations, Nationalities and Peoples Region, Ethiopia
No full textConducted under the AfricaRISING project, the overall objective of the study was to characterize local knowledge of farmers about resources which their livelihood depends on in Lemo woreda, Southern Nations, Nationalities and Peopleâs Region (SNNPR). This research is one of the several studies that are geared towards contributing to the achievement of sustainable tree-crop-livestock intensification as a pillar for the Ethiopian Climate Resilient Green Economy Initiative by providing opportunities for integrating early win tree species and management options in fields, farms and landscapes customized to local conditions and circumstances. Therefore, the main goal of the study was to identify opportunities through which trees-crop-livestock mixed system can be sustainably intensified to contribute towards achieving whole System Level Outcomes (SLOâÂÂs) namely: reducing rural poverty and promoting income diversification, improving food security, improving nutrition and health and ensuring sustainable management of natural resources. Specific objectives of the study were: 1. To assess land use and livelihood strategies at the household level 2. To identify and map out community resources 3. To determine temporal variation in availability of provisioning resources (livestock feed, crops, income, fuel, etc.) 4. To characterize existing tree cover and assess the drivers of land use/ tree cover change 5. To identify existing challenges and assess opportunities for sustainable intensificatio

Analisis Kondisi Hidrologi Daerah Aliran Sungai (DAS) Way Besay dengan menggunakan model Flow Persistence
No full textHydrological function can be used as tools to assess the hydrology condition of watershed. Hydrological assessment with a simple approach is expected to be a bridge to overcome the problems related with error because the number of suspected input in hydrological models. Flow Persistence Model (FlowPer) which is based on autocorrelation between today and the next day discharge will be able to answer these problems. This model calculates a value that can indicate the behavior of the river flow and provide information about watershed condition. Way Besay watershed (415 km2), Lampung is used to test the FlowPer model ability by comparing three scenarios of land cover change; actual (the real condition), deforestation (describe degraded condition) and reforestation (describe improved condition). There are two main steps in this study: (1) discharge simulation based on three conditions using GenRiver model and (2) Calculation of FP value based on simulation discharge using FlowPer model. The average of the FP value over 31 years of simulation (1976-2006) showed the same value between the actual and the deforestation condition, 0.85. However, the changes of FP value in deforestation condi
tion have a tendency to decline over 31 years. Otherwise, the changes of FP value in actual condition has a table tendency. The reforestation condition showed a higher value than actual and deforestation condition, 0.88. This means that the value of FP can be used as assessment tools to assess the hydrology condition of watershed

Africa RISING project: Local agro-ecological knowledge as a basis for sustainable intensification of tree- crop- livestock systems in the Ethiopian highlands: Sinana Woreda, Oromo Region
No full textThis study provides results from local knowledge studies conducted in Sinana woreda, Oromo region. The local knowledge was used as a means of understanding fine-scale variation in a non-homogenous smallholder system in the wheat-belt of the Ethiopian highlands. The research was supported through the USAID funded project Africa RISING (Research in Sustainable Intensification for the Next Generation). The project was launched as part of the US government’s Feed the Future initiative to address global hunger and food security issues in key farming systems in sub-Saharan Africa. This study was focussed on identifying existing sustainable intensive agricultural methods in Sinana woreda, Oromo region. The study also collected local knowledge on agricultural methods so as to assist in the development and implementation of appropriately adapted technologies to intensify production of crops, livelihood and household production without extending the areas subject to cultivation. The research objectives of the study were: · To characterize agro-ecological knowledge of farmers in the Africa RISING project sites · To identify and map out community resources · To assess land use and livelihood strategies at the household level · To characterise existing tree cover and assess the drivers of tree cover change · To determine temporal variation in availability of provisioning services (income, fuel, livestock feed, crops, labour.

Replication data for: Carbon sequestration by Dacryodes edulis: implication for the opportunities of Payment for Environmental Services (PES)
No full textIn order to fight against climate change through the development of profitable systems of production, it was necessary to study the influence of propagule of Dacryodes edulis on the carbon sequestration in plantations containing African Plum and to deduce their opportunities to the PES. The present study was carried out in the experimental plots of ICRAF at Mbalmayo. From the data collected, the results have shown that the average biomass, carbon stock and CO2 sequestered are higher in cutting's plots (268.1 ñ 191.3) compared to the populations of marcots (217.4 ñ 127.9) and of seedlings (131.0 ñ 93.63). No significant difference was observed between CO2 sequestered in the population of cuttings and marcots (F2; 85 = 5.256; à= 0.569 > 5%). An evaluation of the potential incomes that could be generated from the different types of propagules gave 129,595 Fcfa/ha, 105,085 Fcfa/ha and finally 63,320 Fcfa/ha for the population of cuttings, marcots and seedlings respectively. Theimplication for theopportunities related to the PES via the CDM increase with the capacity of CO2 sequestration indicates that the populations of trees from cuttings will offer more incomesin the case of carbon marketthan those from other propagules
Towards Productive Landscapes
No full textBeginning in the mid-2000s the ecosystem service (ES) framework developed by the Millennium Ecosystem Assessment  and a performance-based incentive mechanism for climate-change mitigation through REDD+ gained immediate and widespread acceptance. Payment for Environmental Services (PES) or, more generally, Rewards for Ecosystem Services (RES) is becoming increasingly popular in Asia (van Noordwijk and Leimona 2010). They complement rule-based initiatives (for example, land tenure systems and land-use planning) and economic instruments (for example, taxes and subsidies) in achieving conservation and development objectives
Replication Data for: Enrichment planting using native species (Dipterocarpaceae) with local farmers in rubber smallholdings in Sumatra, Indonesia
No full textDipterocarp species grow well in rubber plantings and do not suffer from mycobionts and abiotic factors such as soil and microclimate (particularly light availability).Here we report on the early growth of meranti in rubber agroforests in three villages in Bungo district and farmers participation in tree enrichment planting in rubber smallholdings. Survival rate of S. leprosula six months after planting ranged from 46.5 percent to 59.2 percent in the three plots and remained the same at 12 months after planting. Survival rate was lowest at the Tebing Tinggi site because wild pig (Sus scrofa) attacked. Height growth was greatest in Dusan Danau while growth in stem diameter was greatest in Dusan Danau and Tebing Tinggi. The poor growth of S. leprosula in Lubuk Beringin was the result of poor maintenance, particularly lack of weeding, by the farmer at that site. Active participation of farmers in restoration activities is essential to achieve high survival rate and performance of the planted seedlings
