    Following discussions at the 6th International Nitrogen Conference, Kampala (24th-27th November 2013), the delegates agreed the Kampala Statement-for-Action on Reactive Nitrogen in Africa and Globally. The Statement-for-Action highlights the global challenge of aiming for just enough nitrogen: enough to meet human needs for food, fuel and fibre, while avoiding excess that contributes to air and water pollution, climate change and ecosystem degradation. The following priorities for Africa are highlighted: (i) Sub-Saharan African agriculture needs to be part of the solution to regional and world food security. This will require restoring and sustaining the fertility of Sub-Saharan African soils through better use of fertilizers in combination with other nutrient sources, such as organic matter and biological fixation. (ii) Smart input subsidy schemes helping to trigger profitable nutrient use should take care that increases in fertilizer find a balance between food security and reducing environmental effects, while recognizing that, (iii) Africa is already facing environmental challenges of nitrogenous air and water pollution even with current levels of nitrogen input. Current nitrogen inputs are thought to be mainly from sources other than chemical nitrogen fertilizers (e.g., biological nitrogen fixation, organic nitrogen inputs, wastewater), though further study is needed to demonstrate apportionment between nitrogen sources and sinks. The following global priorities are highlighted: (i) Improving nitrogen management should be incorporated as a critical component across the Sustainable Development Goals. (ii) The benefits of reducing nitrogen losses from agriculture, industry, transport and energy, of improved waste treatment and of better-informed individuals and institutions should be highlighted, including an emphasis on innovative nutrient recycling and on equitable diet and energy choices. (iii) There is a need for innovation and increased awareness on the nitrogen challenge, including through better communication, education and training. (iv) Solutions to the nitrogen issue should be tuned to regional conditions and require cross-ministerial, trans-disciplinary, multi-sectoral cooperation to create effective policies that fulfill regional and global commitments.

    Payment for environmental services (PES) projects can potentially improve environmental and livelihood outcomes. While pilot projects offer valuable lessons, these are often lost especially if the project fails. Here we assess how and why a forest-for-carbon linked charcoal production project, developed in Central Uganda under the Clean Development Mechanism, failed to achieve its goals (e.g.collaborative establishment of a charcoal production plantation using indigenous species and improved forest protection). We draw upon interviews and focus group discussions with project participants, non-participants and forest authorities. Findings suggest that inadequate project benefits, conflicts over project goals, distrust, poor communication and weak institutional capacity undermined the likelihood of project success. Most shortcomings were evident before the project started. Our conclusion is that projects must invest in recognising and addressing challenges in advance. In addition, good pre-implementation assessments, as well as transparent and accountable decision procedures would improve project outcomes.

    OBJECTIVES: Hypertension is a major burden among African migrants, but the extent of the differences in prevalence, treatment, and control among similar African migrants and nonmigrants living in different contexts in high-income countries and rural and urban Africa has not yet been assessed. We assessed differences in hypertension prevalence and its management among relatively homogenous African migrants (Ghanaians) living in three European cities (Amsterdam, London, and Berlin) and nonmigrants living in rural and urban Ghana. METHODS: A multicenter cross-sectional study was conducted among Ghanaian adults (n = 5659) aged 25-70 years. Comparisons between sites were made using prevalence ratios with adjustment for age, education, and BMI. RESULTS: The age-standardised prevalence of hypertension was 22 and 28% in rural Ghanaian men and women. The prevalence was higher in urban Ghana [men, 34%; adjusted prevalence ratio = 1.37, 95% confidence interval (CI), 1.10-1.70]; and much higher in migrants in Europe, especially in Berlin (men, 57%; prevalence ratio = 2.21, 1.78-2.73; women, 51%; prevalence ratio = 1.74, 1.45-2.09) than in rural Ghana. Hypertension awareness and treatment levels were higher in Ghanaian migrants than in nonmigrant Ghanaians. However, adequate hypertension control was lower in Ghanaian migrant men in Berlin (20%; prevalence ratio = 0.43 95%, 0.23-0.82), Amsterdam (29%; prevalence ratio = 0.59, 0.35-0.99), and London (36%; prevalence ratio = 0.86, 0.49-1.51) than rural Ghanaians (59%). Among women, no differences in hypertension control were observed. About 50% of migrants to 85% of rural Ghanaians with severe hypertension (Blood pressure > 180/110) were untreated. Antihypertensive medication prescription patterns varied considerably by site. CONCLUSION: Hypertension prevalence, awareness, and treatment levels were generally higher in African migrants, but blood pressure control level was lower in Ghanaian migrant men compared with their nonmigrant peers. Further work is needed to identify key underlying factors to support prevention and management efforts.Supplement Figure 1, http://links.lww.com/HJH/A831.

    Abstract Contaminated areas represent a crucial concern in contemporary planning all over the world. The absence of shared value for such areas leads to abandonment and soil sealing specially if such areas have lost their agricultural potential. The European Project LIFE/ENV/IT/275 Ecoremed has implemented a protocol for the bioremediation of contaminated soils in Campania region. The cultivation of no food crops (Poplar and Giant reed) is proposed as buffer crops waiting for the characterization of the areas. This facilitates the uptake of the mineral contaminants and the biodegradation of organic compounds reducing the risk for leaching and the run off of harmful contaminants that would occur on bare soils. The study discusses a new approach to land use change (LUC) assessment based on environmental and socio-economic factors, evaluated through GIS tool and decision support software (ArcGIS/ILWIS). Literature data have been used to assess the current value of the ecosystem services (ES) provided by such crops (€/ha/year) and the benefits that people obtained from ecosystems. Three scenarios have sorted out and compared through multicriteria analysis. Moving from the deep knowledge of the environmental condition of the territory the study shows the alternative ES values of the land use change starting from no-change scenario to energy crops (Poplar and Giant reed), to abandonment. Results show that is possible to asses an increase of the ES value, both in case of a private and public action, also referring to the opportunities for farmers income in the short and medium-long period.

    AbstractBACKGROUNDThis study investigates the level of design and operation of food safety management systems (FSMS) of farmers and export traders in Kenya and Uganda. FSMS diagnostic tools developed for the fresh produce chain were used to assess the levels of context riskiness, FSMS activities and system output in primary production (n = 60) and trade (n = 60). High‐risk context characteristics combined with basic FSMS are expected to increase the risk on unsafe produce.RESULTSIn Uganda both farmers and export traders of hot peppers operate in a high‐ to moderate‐risk context but have basic FSMS and low systems output. In Kenya, both farmers and export traders of green beans operate in a low‐ to moderate‐risk context. The farmers have average performing FSMS, whereas export trade companies showed more advanced FSMS and system output scores ranging from satisfactory to good.CONCLUSIONLarge retailers supplying the EU premium market play a crucial role in demanding compliance with strict voluntary food safety standards, which was reflected in the more advanced FSMS and good system output in Kenya, especially traders. In Kenya, a clear shift in more fit‐for‐purpose FSMS and higher system output was noticed between farms and trade companies. In the case of Uganda, traders commonly supply to the less demanding EU wholesale markets such as ethnic specialty shops. They only have to comply with the legal phytosanitary and pesticide residue requirements for export activities, which apparently resulted in basic FSMS and low system output present with both farmers and traders. © 2015 Society of Chemical Industry

    The dynamics in livelihood needs of people at the fringes of tropical forests have increased the stakes and management challenges of biodiversity worldwide. Since the adoption of the Convention on Biological Diversity in Rio de Janeiro in 1992, the importance of biodiversity has been emphasized in several international agreements. However, the incentives to implement such agreements in poor countries are lacking. The present study characterised the determinants of deforestation, and forest management practices within Mabira Forest Reserve (MFR) in central Uganda. This was done within the context of the evolution of the policy and legal frameworks of Uganda. Literature on MFR as well as the policy and legal framework on forests and related resources was reviewed. The results show that evolution of the forest policy was characterised by limited input from key stakeholders. Moreover, there has been political interference and limited sharing of benefits amid failure to harmonize the forestry policy with relevant policies of related sectors. Consequently, deforestation has continued. To address this anomaly, we encourage the involvement of all key stakeholders including local people in designing management guidelines and sharing benefits from forests as an incentive for participation to promote sustainable forest growth. This is crucial for the success of forest restoration programmes in the tropics.

    The farms of fresh produce farmers are major sources of food contamination by microbiological organisms and chemical pesticides. In view of their choice for farming practices, producers are influenced by food safety requirements. This study analyzes the role of food safety standard certification toward the maturity of food safety management systems (FSMS) in the primary production of fresh produce. Kenya and Uganda are two East African countries that export green beans and hot peppers, respectively, to the European Union but have contrasting features in terms of agricultural practices and certification status. In the fresh produce chain, a diagnostic instrument for primary production was used to assess context factors, core control and assurance activities, and system output to measure the performance of FSMS for certified green bean farms in Kenya and noncertified hot pepper farms in Uganda. Overall, our findings show that in Uganda, noncertified hot pepper farms revealed only a "basic level of control and assurance" activities in their FSMS, which was not satisfactory, because no insight into potential pesticide microbial contamination was presented by these farmers. On the other hand, certified green bean farms in Kenya had an "average level of control and assurance," providing insight into the delivered food safety and quality by the farmers. Farm size did not impact the maturity level of FSMS. This study confirms the role played by food safety standard certification toward the maturity of FSMS implemented in developing countries and demonstrates the possibility of Ugandan farms to upgrade agricultural practices in the fresh produce sector.

    Small-scale excavations were recently undertaken at the site of Ukunju Cave in the Mafia Archipelago, Tanzania, to collect new bioarchaeological and material culture data relating to the site's occupation and the nature of early subsistence and long-distance trade in the region. Our findings suggest that occupation of the cave began during the Middle Iron Age (MIA, seventh to tenth centuries AD), as indicated by the presence of local Early Tana Tradition (ETT)/Triangular Incised Ware (TIW) pottery in the lowest layers above bedrock, as well as small quantities of imported ceramics and glass beads also dating from the mid- to the late first millennium AD. Small assemblages of faunal and botanical remains, including introduced African crops (pearl millet, sorghum, baobab and possibly cowpea) were found in association with these finds, indicating that these MIA communities practised a mixed economy of fishing, domestic livestock keeping and agriculture. In addition, the presence of cotton suggests they may h...

    Field measured estimates of aboveground biomass (AGB) in the mountainous region of Bwindi Impenetrable National Park ('Bwindi'), Uganda were used to train remote sensing models in order to estimate AGB within the park. AGB estimates were extrapolated using dual-polarization radar satellite data from ALOS PALSAR, optical imagery from Landsat 7 and a fusion of both, and compared to field estimates as indicators of the model prediction strength. Significant geolocation errors existed in the radar data due to the extreme terrain. Fusing the radar and optical data using the non-parametric algorithm Random Forest (RF) in R, provided lower error than using either radar or optical data alone (RMSE ∼120 Mg ha-1), however, saturation at higher biomass levels was evident. The AGB in Bwindi was estimated at 8.91 Tg ± 0.39 Tg (260.9 Mg ha-1 ± 11.4 Mg ha-1).

    We explore and compare quantities and patterns of Soil Organic Carbon (SOC) in protected forest and neighboring land around Bwindi Impenetrable National Park (a mountain protected area in Southwestern Uganda). We assessed paired sites of natural forest and major land uses (potato, tea and grazing lands) converted between 1973 and 2010. These pairings were replicated at three altitudinal zones. Plots (20. m by 50. m) were demarcated within each site. Five composite soil and core samples were obtained from 0 to 15. cm (top-soil) and 15-30. cm (sub-soil) at each plot. In total, 192 composite soil and core samples were collected. Within forest we found marked site to site variation in SOC from 54.6 to 82.6. Mg/ha. There was a tendency for higher SOC in converted land, associated with higher bulk density suggesting quality based land use selection with forest left on inferior soils. Cultivation, landscape position, slope and sampling depth were all significantly (P < 0.05) related to variation in SOC stocks following forest conversion but time since conversion had no detectable impact. Interestingly, there was no significant relationship between SOC in the top and sub-soils. Higher SOC is largely determined by higher bulk density. The large SOC stocks in these afro-montane soils are less predictable and more persistent than anticipated.

    Following discussions at the 6th International Nitrogen Conference, Kampala (24th-27th November 2013), the delegates agreed the Kampala Statement-for-Action on Reactive Nitrogen in Africa and Globally. The Statement-for-Action highlights the global challenge of aiming for just enough nitrogen: enough to meet human needs for food, fuel and fibre, while avoiding excess that contributes to air and water pollution, climate change and ecosystem degradation. The following priorities for Africa are highlighted: (i) Sub-Saharan African agriculture needs to be part of the solution to regional and world food security. This will require restoring and sustaining the fertility of Sub-Saharan African soils through better use of fertilizers in combination with other nutrient sources, such as organic matter and biological fixation. (ii) Smart input subsidy schemes helping to trigger profitable nutrient use should take care that increases in fertilizer find a balance between food security and reducing environmental effects, while recognizing that, (iii) Africa is already facing environmental challenges of nitrogenous air and water pollution even with current levels of nitrogen input. Current nitrogen inputs are thought to be mainly from sources other than chemical nitrogen fertilizers (e.g., biological nitrogen fixation, organic nitrogen inputs, wastewater), though further study is needed to demonstrate apportionment between nitrogen sources and sinks. The following global priorities are highlighted: (i) Improving nitrogen management should be incorporated as a critical component across the Sustainable Development Goals. (ii) The benefits of reducing nitrogen losses from agriculture, industry, transport and energy, of improved waste treatment and of better-informed individuals and institutions should be highlighted, including an emphasis on innovative nutrient recycling and on equitable diet and energy choices. (iii) There is a need for innovation and increased awareness on the nitrogen challenge, including through better communication, education and training. (iv) Solutions to the nitrogen issue should be tuned to regional conditions and require cross-ministerial, trans-disciplinary, multi-sectoral cooperation to create effective policies that fulfill regional and global commitments.

    Payment for environmental services (PES) projects can potentially improve environmental and livelihood outcomes. While pilot projects offer valuable lessons, these are often lost especially if the project fails. Here we assess how and why a forest-for-carbon linked charcoal production project, developed in Central Uganda under the Clean Development Mechanism, failed to achieve its goals (e.g.collaborative establishment of a charcoal production plantation using indigenous species and improved forest protection). We draw upon interviews and focus group discussions with project participants, non-participants and forest authorities. Findings suggest that inadequate project benefits, conflicts over project goals, distrust, poor communication and weak institutional capacity undermined the likelihood of project success. Most shortcomings were evident before the project started. Our conclusion is that projects must invest in recognising and addressing challenges in advance. In addition, good pre-implementation assessments, as well as transparent and accountable decision procedures would improve project outcomes.

    OBJECTIVES: Hypertension is a major burden among African migrants, but the extent of the differences in prevalence, treatment, and control among similar African migrants and nonmigrants living in different contexts in high-income countries and rural and urban Africa has not yet been assessed. We assessed differences in hypertension prevalence and its management among relatively homogenous African migrants (Ghanaians) living in three European cities (Amsterdam, London, and Berlin) and nonmigrants living in rural and urban Ghana. METHODS: A multicenter cross-sectional study was conducted among Ghanaian adults (n = 5659) aged 25-70 years. Comparisons between sites were made using prevalence ratios with adjustment for age, education, and BMI. RESULTS: The age-standardised prevalence of hypertension was 22 and 28% in rural Ghanaian men and women. The prevalence was higher in urban Ghana [men, 34%; adjusted prevalence ratio = 1.37, 95% confidence interval (CI), 1.10-1.70]; and much higher in migrants in Europe, especially in Berlin (men, 57%; prevalence ratio = 2.21, 1.78-2.73; women, 51%; prevalence ratio = 1.74, 1.45-2.09) than in rural Ghana. Hypertension awareness and treatment levels were higher in Ghanaian migrants than in nonmigrant Ghanaians. However, adequate hypertension control was lower in Ghanaian migrant men in Berlin (20%; prevalence ratio = 0.43 95%, 0.23-0.82), Amsterdam (29%; prevalence ratio = 0.59, 0.35-0.99), and London (36%; prevalence ratio = 0.86, 0.49-1.51) than rural Ghanaians (59%). Among women, no differences in hypertension control were observed. About 50% of migrants to 85% of rural Ghanaians with severe hypertension (Blood pressure > 180/110) were untreated. Antihypertensive medication prescription patterns varied considerably by site. CONCLUSION: Hypertension prevalence, awareness, and treatment levels were generally higher in African migrants, but blood pressure control level was lower in Ghanaian migrant men compared with their nonmigrant peers. Further work is needed to identify key underlying factors to support prevention and management efforts.Supplement Figure 1, http://links.lww.com/HJH/A831.

    Abstract Contaminated areas represent a crucial concern in contemporary planning all over the world. The absence of shared value for such areas leads to abandonment and soil sealing specially if such areas have lost their agricultural potential. The European Project LIFE/ENV/IT/275 Ecoremed has implemented a protocol for the bioremediation of contaminated soils in Campania region. The cultivation of no food crops (Poplar and Giant reed) is proposed as buffer crops waiting for the characterization of the areas. This facilitates the uptake of the mineral contaminants and the biodegradation of organic compounds reducing the risk for leaching and the run off of harmful contaminants that would occur on bare soils. The study discusses a new approach to land use change (LUC) assessment based on environmental and socio-economic factors, evaluated through GIS tool and decision support software (ArcGIS/ILWIS). Literature data have been used to assess the current value of the ecosystem services (ES) provided by such crops (€/ha/year) and the benefits that people obtained from ecosystems. Three scenarios have sorted out and compared through multicriteria analysis. Moving from the deep knowledge of the environmental condition of the territory the study shows the alternative ES values of the land use change starting from no-change scenario to energy crops (Poplar and Giant reed), to abandonment. Results show that is possible to asses an increase of the ES value, both in case of a private and public action, also referring to the opportunities for farmers income in the short and medium-long period.

    AbstractBACKGROUNDThis study investigates the level of design and operation of food safety management systems (FSMS) of farmers and export traders in Kenya and Uganda. FSMS diagnostic tools developed for the fresh produce chain were used to assess the levels of context riskiness, FSMS activities and system output in primary production (n = 60) and trade (n = 60). High‐risk context characteristics combined with basic FSMS are expected to increase the risk on unsafe produce.RESULTSIn Uganda both farmers and export traders of hot peppers operate in a high‐ to moderate‐risk context but have basic FSMS and low systems output. In Kenya, both farmers and export traders of green beans operate in a low‐ to moderate‐risk context. The farmers have average performing FSMS, whereas export trade companies showed more advanced FSMS and system output scores ranging from satisfactory to good.CONCLUSIONLarge retailers supplying the EU premium market play a crucial role in demanding compliance with strict voluntary food safety standards, which was reflected in the more advanced FSMS and good system output in Kenya, especially traders. In Kenya, a clear shift in more fit‐for‐purpose FSMS and higher system output was noticed between farms and trade companies. In the case of Uganda, traders commonly supply to the less demanding EU wholesale markets such as ethnic specialty shops. They only have to comply with the legal phytosanitary and pesticide residue requirements for export activities, which apparently resulted in basic FSMS and low system output present with both farmers and traders. © 2015 Society of Chemical Industry

    The dynamics in livelihood needs of people at the fringes of tropical forests have increased the stakes and management challenges of biodiversity worldwide. Since the adoption of the Convention on Biological Diversity in Rio de Janeiro in 1992, the importance of biodiversity has been emphasized in several international agreements. However, the incentives to implement such agreements in poor countries are lacking. The present study characterised the determinants of deforestation, and forest management practices within Mabira Forest Reserve (MFR) in central Uganda. This was done within the context of the evolution of the policy and legal frameworks of Uganda. Literature on MFR as well as the policy and legal framework on forests and related resources was reviewed. The results show that evolution of the forest policy was characterised by limited input from key stakeholders. Moreover, there has been political interference and limited sharing of benefits amid failure to harmonize the forestry policy with relevant policies of related sectors. Consequently, deforestation has continued. To address this anomaly, we encourage the involvement of all key stakeholders including local people in designing management guidelines and sharing benefits from forests as an incentive for participation to promote sustainable forest growth. This is crucial for the success of forest restoration programmes in the tropics.

    The farms of fresh produce farmers are major sources of food contamination by microbiological organisms and chemical pesticides. In view of their choice for farming practices, producers are influenced by food safety requirements. This study analyzes the role of food safety standard certification toward the maturity of food safety management systems (FSMS) in the primary production of fresh produce. Kenya and Uganda are two East African countries that export green beans and hot peppers, respectively, to the European Union but have contrasting features in terms of agricultural practices and certification status. In the fresh produce chain, a diagnostic instrument for primary production was used to assess context factors, core control and assurance activities, and system output to measure the performance of FSMS for certified green bean farms in Kenya and noncertified hot pepper farms in Uganda. Overall, our findings show that in Uganda, noncertified hot pepper farms revealed only a "basic level of control and assurance" activities in their FSMS, which was not satisfactory, because no insight into potential pesticide microbial contamination was presented by these farmers. On the other hand, certified green bean farms in Kenya had an "average level of control and assurance," providing insight into the delivered food safety and quality by the farmers. Farm size did not impact the maturity level of FSMS. This study confirms the role played by food safety standard certification toward the maturity of FSMS implemented in developing countries and demonstrates the possibility of Ugandan farms to upgrade agricultural practices in the fresh produce sector.

    Small-scale excavations were recently undertaken at the site of Ukunju Cave in the Mafia Archipelago, Tanzania, to collect new bioarchaeological and material culture data relating to the site's occupation and the nature of early subsistence and long-distance trade in the region. Our findings suggest that occupation of the cave began during the Middle Iron Age (MIA, seventh to tenth centuries AD), as indicated by the presence of local Early Tana Tradition (ETT)/Triangular Incised Ware (TIW) pottery in the lowest layers above bedrock, as well as small quantities of imported ceramics and glass beads also dating from the mid- to the late first millennium AD. Small assemblages of faunal and botanical remains, including introduced African crops (pearl millet, sorghum, baobab and possibly cowpea) were found in association with these finds, indicating that these MIA communities practised a mixed economy of fishing, domestic livestock keeping and agriculture. In addition, the presence of cotton suggests they may h...

    Field measured estimates of aboveground biomass (AGB) in the mountainous region of Bwindi Impenetrable National Park ('Bwindi'), Uganda were used to train remote sensing models in order to estimate AGB within the park. AGB estimates were extrapolated using dual-polarization radar satellite data from ALOS PALSAR, optical imagery from Landsat 7 and a fusion of both, and compared to field estimates as indicators of the model prediction strength. Significant geolocation errors existed in the radar data due to the extreme terrain. Fusing the radar and optical data using the non-parametric algorithm Random Forest (RF) in R, provided lower error than using either radar or optical data alone (RMSE ∼120 Mg ha-1), however, saturation at higher biomass levels was evident. The AGB in Bwindi was estimated at 8.91 Tg ± 0.39 Tg (260.9 Mg ha-1 ± 11.4 Mg ha-1).

    We explore and compare quantities and patterns of Soil Organic Carbon (SOC) in protected forest and neighboring land around Bwindi Impenetrable National Park (a mountain protected area in Southwestern Uganda). We assessed paired sites of natural forest and major land uses (potato, tea and grazing lands) converted between 1973 and 2010. These pairings were replicated at three altitudinal zones. Plots (20. m by 50. m) were demarcated within each site. Five composite soil and core samples were obtained from 0 to 15. cm (top-soil) and 15-30. cm (sub-soil) at each plot. In total, 192 composite soil and core samples were collected. Within forest we found marked site to site variation in SOC from 54.6 to 82.6. Mg/ha. There was a tendency for higher SOC in converted land, associated with higher bulk density suggesting quality based land use selection with forest left on inferior soils. Cultivation, landscape position, slope and sampling depth were all significantly (P < 0.05) related to variation in SOC stocks following forest conversion but time since conversion had no detectable impact. Interestingly, there was no significant relationship between SOC in the top and sub-soils. Higher SOC is largely determined by higher bulk density. The large SOC stocks in these afro-montane soils are less predictable and more persistent than anticipated.
