Land tenure and natural resource management

The devastating environmental effects of deforestation and the exploitation of other natural resources in the developing world have been well documented, yet their impact on local communities has received far less attention. This report looks at how land degradation and deforestation are being addressed at the local level, where households have experienced the reduction of farm size and the decline of natural resources. Through a comparison of Asia and Africa, the evolution of land tenure institutions within diverse cultural, natural, and policy environments is examined. Specific topics include the evolution of customary land tenure, the impacts of land tenure policies, and common property management. The editors conclude that the best strategy for managing land and forest resources lies in promoting the establishment of property rights and investment in the improvement of the natural resource base.Land use. ,Land tenure. ,Asia. ,Africa. ,Forest management. ,Natural resources. ,Viet Nam ,Vietnam ,

The role of tenure in the management of trees at the community level: theoretical and empirical analyses from Uganda and Malawi

This paper examines the effects of tenure on tree management at a community level. First, several important conceptual issues arising from this particular meso-level focus are discussed. Second, a description of the key tenure and tree management issues in Uganda and Malawi is presented. In each case, data representing changes in land use and tree cover between the 1960-70s and 1990s are analyzed. In both countries, there has been significant conversion of land from woodlands to agriculture. Tree cover has been more or less maintained over time in Uganda but has decreased in Malawi. Lastly, the paper explores the relationships between tenure and tree management using econometric techniques. Tenure is found to be linked to land-use and tree-cover change in both countries, though it is not necessarily the most important factor (e.g., population pressure is the key driving force for land-use change). In Uganda, conversion of land was more rapid under the customary tenure system and tree cover on nonagricultural land better maintained under the mailo system. In Malawi there was more rapid land-use conversion and tree cover depletion where there were more changes to traditional tenure systems taking place.

Initiatives for rural development through collective action: the case of household participation in group activities in the highlands of Central Kenya

"Dimensions of the nature, scope, and complexity of collective action in Kenya have evolved over many years. In studying collective action, the aim is to understand why and how people participate in networks of trust. The purpose of this study was to investigate the different objectives that farmers pursue through collective action with the aim of understanding the patterns of people's participation in collective action, identify factors that influence people to join groups, and identify the costs and benefits of participating in activities of groups. The study was carried out in four sites spread across the highlands of central Kenya. Data was collected from a total of 442 households, focusing on whether members of those households belonged to groups and if so, what type of groups these were and their activities. In addition we looked at how these groups functioned and identified some of the contributions members make to these groups and the benefits from the same. The analysis shows that collective action is used to accomplish a range of activities for different socioeconomic categories and that the majority of households in central Kenya engage in some form of group activity.... The study suggests that where institutions and policies that promote individual or private sector growth are weak, collective action can help to overcome these weaknesses and connect individuals in these institutions and policies." from Author's AbstractCollective action, Trust, Community participation, cost benefit analysis, Household surveys, Gender,

Population, land tenure, and natural resource management: the case of customary land area in Malawi

This paper uses cross section-time series data on 57 communities in Malawi to determine statistically the factors determining changes in land use, tree cover, and crop yield. The econometric model is developed from a theoretical model which also endogenizes population growth and prevailing land tenure institutions within the customary sector of Malawi. The analysis reflects changes between 1971 and 1995, utilizing aerial photos taken at these dates and complementing these with field surveys. The data show a deterioration of Malawi's natural resource base: declining yields, loss of tree cover, and near exhaustion of land for agricultural expansion. Key findings are that population pressure induces land conversion but not yield or tree cover change; the matrilocal system of household residence is negatively associated with tree cover but induces agricultural conversion; and there is some improvement in management of resources as their scarcity increases. Policy recommendations include greater focus on agroforestry to increase tree cover as woodland areas are poorly managed, and increased effort to improve market integration since this benefits crop yields without adverse effects on tree cover.Crop yields., Econometric models., Population density., Forest management., Malawi.,

Population pressure, land tenure, and tree resource management in Uganda:

This study uses aerial photographs and survey data from sixty four parishes in east-central Uganda to identify the factors affecting conversion of woodlands and traditional grazing areas to agriculture. Regression analysis shows that customary land tenure institutions, greater population pressure and poor access to markets are significant causes of land conversion to agriculture, and hence to loss of trees. Private ownership of converted land promotes greater integration of trees and crops and leads to the highest density of trees on agricultural land. Given that continuing population growth will lead to further land conversion to agriculture, the best prospect for maintaining or increasing tree populations lies with agroforestry on cultivated land.Land use., Trees., Forest management., Uganda.,

Property rights, collective action, and agroforestry

"In this brief, we explore the role that social institutions — specifically property rights and collective action — may play in the developmentment of agroforestry.... In the future, property rights and collective action will play increasingly pivotal roles in defining rights and responsibilities over the externalities of tree management practices. As stakeholders recognize the need for effective management of, for example, the erosion resulting from tree felling or rights to carbon sequestration from tree planting, they will increasingly value and depend on the institutions that protect their property rights." from Text.Property rights ,Tree planting ,Public goods ,Poverty alleviation ,Collective action ,

Heterogeneous treatment effects of integrated soil fertility management on crop productivity: Evidence from Nigeria

This study compares the impacts of integrated soil fertility management (ISFM) on crop production with use of either mineral fertilizer or organic manure alone. We also investigate the conditions under which .ISFM technology has greater beneficial effects on yields and the factors constraining its uptake. To answer these questions, the study uses a cross-sectional, plot-level data set collected in Nigeria by the International Food Policy Research Institute and the World Bank in 2009. Using both quasi experimental matching estimators and multivariate regression approaches, it finds that overall ISFM has robustly significant positive effects on crop production. The study also finds that ISFM positively affects crop production on plots with customary tenure, sandy soils, and clay soils—conditions that are normally perceived to be less favorable for crop production. The results also show ISFM to be more effective on plots with mild erosion or no erosion. On the constraints, we find that households with limited livestock, equipment, labor, and land are less likely to use ISFM technology, and the extension services currently do not seem to be disseminating ISFM. This evidence provides strong support for efforts to promote ISFM in Nigeria and in other regions with comparable conditions, but adequate attention must be paid to the biophysical conditions of the plots and the household's access to labor endowments, livestock, equipment, and tenure conditions if this technology is to be scaled up and more widely used in Sub-Saharan Africa.Crop production, Integrated soil fertility management, matching estimators,

Improved fallows in Kenya: history, farmer practice, and impacts

This case study explores the development, dissemination, adoption, and impact of improved tree fallows in rural western Kenya. The processes of technology development and dissemination throughout the region are described and analyzed. To analyze adoption and impact, the paper applies a variety of different data collection methods as well as samples from both pilot areas where researchers maintained a significant presence and non-pilot areas where farmers learned of the technologies through other channels. Sample sizes for the quantitative analysis ranged from almost 2,000 households for measuring the adoption process to just over 100 households for measuring impact indicators. Qualitative methods included long-term case studies for 40 households and focus group discussions involving 16 different groups. The paper describes the ways in which farmers used and modified improved fallow practices. Discussion also examines the types of households using fallows and benefiting from their use.
