GENDER Gender Is a bit trickier. Gender as a concept refers to the roles and responsibilities of boys, men, girls, and women influenced by the society we live in, our traditions, religion, values, culture, and economy. Gender is about the behaviours that are expected of each gender = Gender is about both men and women. These roles and expectations are learned from childhood, they are not determined by biology.

Deforestation leakage undermines conservation value of tropical and subtropical forest protected areas
Aim: The establishment of protected areas is among the most widespread responses to mitigate species loss. Although protected areas are often assumed to have conservation benefits, negative impacts have also been documented. One potential negative outcome is leakage, whereby protected areas displace land-use activities harmful to conservation into adjacent areas. This can undermine protection by accelerating loss of species or skewing judgements of effectiveness. This study assessed the prevalence of deforestation leakage in a pan-tropical and subtropical selection of 120 protected areas. Location: Tropical and subtropical forest regions of America, Africa and Asia. Time period: 2001–2017. Major taxa studied: Threatened species of amphibians, birds and terrestrial mammals. Methods: We used Global Forest Change data to assess the average yearly rate of deforestation in protected areas, protected area buffer zones and statistically matched, unprotected control areas. We calculated and compared irreplaceability of habitat for threatened amphibian, bird and terrestrial mammal species between protected areas and buffer zones. Results: In 55 cases, deforestation rates were higher in buffer zones than in protected and control areas, suggesting a relatively high prevalence of deforestation leakage stemming from protected areas. In 78.2% of documented leakage cases, reduced deforestation in protected areas was not sufficient to offset the amount of deforestation in 10 km buffer zones to a level that would be expected without protection. In 90.9% of leakage cases, the irreplaceability of species in the 10 km buffer zone was greater than that of the protected area, implying a negative impact of leakage on threatened species. Main conclusions: The results suggest that protected areas are generally effective at preventing deforestation within their jurisdiction; however, leakage patterns can undermine conservation success because buffer zones often contain habitat for threatened species. We recommend accounting for the possibility of leakage when designing new protected areas and networks. © 2020 The Authors. Global Ecology and Biogeography published by John Wiley & Sons Ltd
What influences the effectiveness of forest conservation interventions in tropical regions? A systematic review
Recent decades have witnessed a proliferation of forest conservation interventions in tropical developing countries. Impact evaluations most frequently report statistically significant but modest conservation results. As tropical deforestation has persisted, how to increase the effectiveness of interventions is an important empirical question. In this article, we reviewed the English-language, peer-reviewed literature about the heterogeneous impacts of forest conservation interventions. Our goal was to synthesize the experimental and quasi-experimental evidence about how two main factors shaped forest conservation outcomes: 1) the design and implementation characteristics that create heterogeneous treatments; and 2) the characteristics of the context that act as moderators of treatment effects. After screening 1,486 studies, we selected 47 papers conducting robust heterogeneity analysis, showing an emerging trend in the literature. We found interventions generally achieve greater conservation results where forests are under higher deforestation pressure or risk. This implies the protection of forests that are most under threat should be prioritized. As the number of heterogenous assessments is limited, it is still difficult to draw other valid lessons about how and under what conditions interventions may be more effective. We thus renew the calls for more rigorous evaluations of forest conservation interventions that go beyond estimating average effects.
Sustained participation in a Payments for Ecosystem Services program reduces deforestation in a Mexican agricultural frontier
Payments for Ecosystem Services (PES) provide conditional incentives for forest conservation. PES short-term effects on deforestation are well-documented, but we know less about program effectiveness when participation is sustained over time. Here, we assess the impact of consecutive renewals of PES contracts on deforestation and forest degradation in three municipalities of the Selva Lacandona (Chiapas, Mexico). PES reduced deforestation both after a single 5-year contract and after two consecutive contracts, but the impacts are only detectable in higher deforestation-risk parcels. Enrollment duration increases PES impact in these parcels, which suggests a positive cumulative effect over time. These findings suggest that improved spatial targeting and longer-term enrollment are key enabling factors to improve forest conservation outcomes in agricultural frontiers.
Biodiversity of the cocoa agroforests of the Bengamisa-Yangambi Forest Landscape in the Democratic Republic of the Congo (DRC)
Cocoa agroforestry has evolved into an accepted natural resource conservation strategy in the tropics. It is regularly proposed as one of the main uses for REDD+ projects (Reducing Emissions from Deforestation and forest Degradation and the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks in developing countries) in the Democratic Republic of the Congo. However, few studies have characterized the cocoa agroforestry systems in this country. Hence, this research proposes to determine the impact of distance from Kisangani (the unique city in the landscape) and land-use intensity on the floristic composition of cocoa agroforests in Bengamisa-Yangambi forest landscape in the Congo Basin. The results revealed that species diversity and density of plants associated with cocoa are influenced by the distance from Kisangani (the main city in the landscape and province). Farmers maintain/introduce trees that play one or more of several roles. They may host caterpillars, provide food, medicine, or timber, or deliver other functions such as providing shade to the cocoa tree. Farmers maintain plants with edible products (mainly oil palms) in their agroforests more than other plants. Thus, these agroforests play key roles in conserving the floristic diversity of degraded areas. As cocoa agroforestry has greater potential for production, biodiversity conservation, and environmental protection, it should be used to slow down or even stop deforestation and forest degradation.
Germplasm Acquisition and Distribution by CGIAR Genebanks
The international collections of plant genetic resources for food and agriculture (PGRFA) hosted by 11 CGIAR Centers are important components of the United Nations Food and Agriculture Organization’s global system of conservation and use of PGRFA. They also play an important supportive role in realizing Target 2.5 of the Sustainable Development Goals. This paper analyzes CGIAR genebanks’ trends in acquiring and distributing PGRFA over the last 35 years, with a particular focus on the last decade. The paper highlights a number of factors influencing the Centers’ acquisition of new PGRFA to include in the international collections, including increased capacity to analyze gaps in those collections and precisely target new collecting missions, availability of financial resources, and the state of international and national access and benefit-sharing laws and phytosanitary regulations. Factors contributing to Centers’ distributions of PGRFA included the extent of accession-level information, users’ capacity to identify the materials they want, and policies. The genebanks’ rates of both acquisition and distribution increased over the last decade. The paper ends on a cautionary note concerning the potential of unresolved tensions regarding access and benefit sharing and digital genomic sequence information to undermine international cooperation to conserve and use PGRFA.
Population status of Boswellia papyrifera woodland and prioritizing its conservation interventions using multi-criteria decision model in northern Ethiopia
Boswellia papyrifera woodland provides considerable economic, ecological and socio-cultural benefits in the drylands of Ethiopia. However, its populations are in rapid decline due to human pressure and environmental degradation. As a consequence, the species is now considered being endangered, demanding an urgent conservation intervention to sustain its existence. This study was carried out in the Abergele district, northern Ethiopia, with objectives to characterize the current population structure of B. papyrifera and prioritize its potential conservation intervention alternatives using Analytical Hierarchy Process (AHP) modelling techniques. The woody species related data were collected from 33 sample plots randomly established in the study area. Data related to the potential intervention alternatives and their evaluating criteria were collected from experts, personal experiences and intensive literature reviews, and then validated using stakeholders’ focus group discussion. Four candidate alternatives were then considered for the AHP: 1) free grazing with no tapping resting period (FGNTR), 2) free grazing with a rotational tapping (FGRT), 3) area exclosure with medium tapping resting period (AEMTR), and 4) area exclosure with long tapping resting period (AELTR). The results showed that the population structure of B. papyrifera is unstable and is characterized by low density (266 trees ha−1), absence of regeneration and saplings (DBH<10 cm) due to different interrelated disturbances such as overgrazing, over tapping, pests, agricultural expansion and poor managements. The overall priority ranking value of all stakeholders using the AHP techniques also indicated that AEMTR (with overall rank value of 0.352) and AELTR (0.294) as the best alternatives strategies, respectively, for sustainable B. papyrifera woodland conservation. For the success of these strategies, their economic impacts at their early implementation stages (5–10 years) should be minimized by collecting different non-timber forest products from the woodland. Continuous capacity building training on sustainable utilizations and managements of B. papyrifera woodland should also be provided for all relevant stakeholders.
Nutrient value of wild fodder species and the implications for improving the diet of mithun (Bos frontalis) in Dulongjiang area, Yunnan Province, China
Wild fodder plants are valuable because they provide an important livestock feed resource globally, especially for smallholder farmers, and have important roles in natural resource management. In-depth knowledge of wild forage plants can motivate local people for feed resource and habitat conservation of threatened herbivores such as Mithun (Bos frontalis). Mithun occur in small patches in the mountains of Dulongjiang, nearby villagers domesticated this animal but left animal to freely graze in the mountains. Many fodder plants occur in these mountains, however, little is known about their nutritional value. We conducted an ethnobotanical survey to document important wild fodder plants consumed by mithun in the Dulongjiang Township. The nutritional content of 21 highly mentioned wild fodder plants in an ethnobotanical survey was examined. Laboratory analysis showed that Fagopyrum dibotrys were the fodder species with the highest crude protein (CP) content (26.89%), followed by Polygonum molle (21.88%) and Hydrangea longipes (21.12%). Synthesis of relative feed value index and grey relational grade, P. molle, H. longipes and Tetrastigma obtectum were ranked the top three nutritional fodders. There was a significant difference between 21 species on their in vitro digestibility and the most highly digestible fodder species was Elatostema hookerianum. Linear model analysis on relationship between frequency of citation of 21 wild forage plants by local farmers and their nutrient composition showed that the frequency was significantly positively correlated with the nutritional value of the feed (R2 = 0.28, P < 0.05). We concluded that these species have high nutritional values to improve mithun production in integrated crop-livestock systems. Fodder species or mixtures of species with useful nutritional characters could be cultivated to improve livestock productivity, habitat conservation including that of mithun and wild forage resource management.
‘We Are Not Bad People’- Bricolage and the Rise of Community Forest Institutions in Burkina Faso
From a critical institutionalism and institutional bricolage perspective, this article analyses what drives institutional change in the commons and the outcomes for forest and people. It builds on the comparison of three neighbouring villages in Burkina Faso that in 1989, expecting higher returns, agreed to release their common lands for the creation of a community forest called Chantier d’Aménagement Forestier (CAF) within an international forestry project. The project created new bureaucratic institutions to replace the pre-existing customary and socially embedded system. Decades later, the three villages display different institutional change pathways and outcomes: one village abandoned the CAF, converted, and sold its forest and land; another maintained the CAF; and a third operates in-between. Using qualitative research methods, we ask why and how these different change trajectories and outcomes occurred among villages of identical cultural and sociopolitical background. The results show that poor design and implementation of the new bureaucratic institutions, as well as their disrespect of customary and socially embedded rules, led to forestland disputes between the villages. The bureaucratic institutions failed to solve those disputes, effectively manage the forest, and share the benefits equitably. This caused local people’s discontent and prompted actions for change. Actors in diverse ways made use of their social networks, agency, and power relations within and between the villages to either reshape, re-interpret or reject the new forest institutions. These processes of institutional bricolage led to highly diverse trajectories of change. The findings demonstrate the crucial role of locals as agents of change from below and question universal claims in institutional theory on how institutions induce rule-guided behaviour and create path dependencies.
Indicators of the genetic diversity of trees – State, pressure, benefit and response. The State of the World’s Forest Genetic Resources – Thematic study
This study, prepared within the ambit of The State of the World’s Forest Genetic Resources, reviews issues related to the development of indicators for tree genetic diversity. It includes a historical account of the development of science-based indicators for tree genetic diversity that embrace ecological surrogates for genetic diversity, the genealogical approach, genetic monitoring of management units, the use of molecular markers, as well as relevant experience from other organisms and policy processes. It also includes a section on relevant data, data sources, and databases. Finally, the study proposes a set of four operational indicators for monitoring tree genetic diversity. The proposed indicators could support efforts towards sustainable forest management, as well as the development of indicators for the post-2020 global biodiversity framework.
