Off‐farm work,land tenancy contracts and investment in soil conservation measures in rural Pakistan

This study examines the impacts of participation in off‐farm work and land tenancy contracts on the intensity of investment in soil‐improving measures and farm productivity. A multivariate Tobit model that accounts for potential endogeneity between the intensity of investment and the off‐farm work and tenancy contract variables is estimated for 341 rural households in Punjab province of Pakistan. An instrumental variable approach is also used to analyse the impact of tenancy contract and off‐farm work on farm productivity. The empirical results show that participation in off‐farm work and tenure security tends to increase the intensity of investment in long‐term soil‐improving measures. We also find that increases in off‐farm work and tenure security exert significant and positive effects on farm productivity.     

Land Tenure,Tenure Security and Farm Efficiency: Panel Evidence from the Philippines

This article tests the relationships among formalised property rights, land tenure contracts and productive efficiency in farming. Using four rounds of panel data from 230 rice farms in the Philippines, we measure the effects of land tenure arrangements on farm efficiency using a stochastic production frontier model. We test for the allocative efficiency of observed land rental markets. We also test how land tenure security affects farmers' investment decisions. Results suggest that, despite the presence of formalised titles, the rental market remains inefficient at allocating land. In contrast, the unformalised tenure contracts used by farmers appear to provide tenure security.     

A model of shifting cultivation: can soil conservation reduce deforestation?

Shifting cultivators manage soil not only by adjusting soil use on already‐cleared lands, as in continuous cultivation, but also by clearing forests to obtain new fertile soils. This study examines the crucial link between on‐farm soil conservation and deforestation in shifting cultivation by modeling forest clearing as an investment in soil for a private farmer. More generally, by doing so the study attempts to integrate deforestation and soil conservation models which have been separately developed in the literature. Our policy goal is to arrest tropical deforestation—as destruction of global commons—caused by land degradation in shifting cultivation while improving the well‐being of poor shifting cultivators. Our integrated approach enables joint policy analyses of deforestation and land degradation. Three welfare‐enhancing policies are considered. The first is agricultural and nonagricultural subsidies affecting farm and nonfarm income opportunities. The second is fiscal and tenure policies affecting discount rates. Our question is whether the link between forest clearing and soil fertility alters the outcomes of these two standard macroeconomic policies commonly found in the literature. The third policy (or program) is various soil conservation measures affecting soil regeneration and erosivity on already‐cleared lands. This article examines a very important question which has received little attention in previous theoretical works: can soil conservation reduce deforestation? This study confirms anti‐deforestation effects of the promotion of nonfarming activities—a common and often emphasized finding in previous works—among shifting cultivators. More importantly, it also demonstrates that improving various soil conservation measures not only discourages forest clearing among shifting cultivators but also tends to have greater effects on forest protection than promoting nonfarming activities. Contrarily, agricultural price subsidy or technological progress gives rise to the opposite outcome, and lowering the farmer's discount rate or improving tenure security encourages him/her to clear more forests just to accumulate soil.     

Does land registration and certification boost farm productivity? Evidence from Ethiopia

According to economic theory, tenure security is an important determinant of agricultural investment and productivity. Land titling has been at the center stage of development efforts of many African countries to boost tenure security. We investigate the productivity impacts of the Ethiopian land registration and certification program, employing propensity score matching method in an effort to create a credible counterfactual. Consistent with theory, we find land registration and certification has robust positive effects on farm productivity. More tentatively, we identify the assurance effect as one probable channel for impact. Households with land certificates are more likely to adopt soil‐fertility management strategies on their plots than households without certificates.     

Does land lease tenure insecurity cause decreased productivity and investment in the sugar industry? Evidence from Fiji

Does land lease tenure insecurity cause decreased productivity and investment in the sugar industry? To answer this question, this study examined the impact of weak formal tenure lease arrangements on tenants’ investment and the productivity of sugarcane in Ba province, Fiji. After controlling for potential endogeneity in the choice of lease tenure using instrumental variables (IV), it was shown that tenants under insecure lease tenure (expiring in 0–5 years) achieve significantly lower yields of sugarcane, by 6.5–11 tonnes per hectare, and plant smaller areas of new sugarcane, by 0.14–0.25 hectares on average, than do tenants under secure lease tenure. Insecure lease tenure also negatively affects chemical fertiliser use, although this impact is not statistically significant. An intervention to improve tenure security would likely enhance the production efficiency of and investment in the Fijian sugarcane industry.     

Fragmented Territories: Incomplete Enclosures and Agrarian Change on the Agricultural Frontier of Samlaut District,North‐West Cambodia

In Cambodia, the interactions between large‐scale land investment and land titling gathered particular momentum in 2012–13, when the government initiated an unprecedented upland land titling programme in an attempt to address land tenure insecurity where large‐scale land investment overlaps with land appropriated by peasants. This paper is based on a spatially explicit ethnography of land rights conducted in the Samlaut district of north‐west Cambodia – a former Khmer Rouge resistance stronghold – in a context where the enclosures are both incomplete and entangled with post‐war, socially embedded land tenure systems. We discuss how this new pattern of fragmentation affects the prevailing dynamics of agrarian change. We argue that it has introduced new forms of exclusion and a generalized perception of land tenure uncertainty that is managed by peasants through the actualization of hybrid land tenure arrangements borrowing from state rules and local consensus. In contrast with common expectations about land formalization, the process reinforces the patterns of social differentiation initiated by land rent capture practices of early migrants and pushes more vulnerable peasants into seeking wage labour and resorting to job migration.     

Endogenous institutional innovation and agroindustrialization on the Peruvian coast

This paper presents an analysis of endogenous institutional innovations that have recently emerged in the agroindustrial zone of Chincha, on the coast of Peru. These innovations include: (1) contracts between agroindustrial firms and large farmers, introduced by the firms themselves to assure timely delivery and compliance with strict requirements implied by the emerging demanding quality and safety standards for agro‐export of processed asparagus; (2) management services exchanged for labor supervision and land collateral in share tenancy contracts between a management company and “farmer companies” of small cotton farmers. These contracts introduced by the management company illustrate those described theoretically by Eswaran and Kotwal [Am. Econ. Rev. 75 (3), 352–367]. The nature and importance of these institutional changes are twofold: (1) They were induced institutional innovations driven by the requirements of agroindustrialization itself. (2) Together they had ambiguous employment and income impacts (tending to the negative). On the one hand, the emergence of asparagus and firm‐farm contracts reduced employment through exclusion of small farms and shifts to capital‐intensive crops. On the other hand, the reinforcement of smallholder cotton and the emergence of farmer companies increased employment and income of smallholders. The institutional innovation allowed them to reduce risk and increase profits and thus access some of the benefits of agroindustrialization and globalization. While processing firm‐farm contracts are common in Peru, as is the presence of NGOs bringing subsidized credit, the private management firm innovation is rare and new in Peru and apparently also in the region, and of great interest. In fact, policymakers and NGOs have recently discovered that this innovation is taking place and are asking hard questions about whether this innovation can and will be diffused. The interest in the private for‐profit institutional change is sharpened by growing doubts about how economically sustainable and widespread a response NGO help can be to small farmers in maintaining their participation in income‐enhancing agroindustrialization. Moreover, with changes in land laws and markets the fluidity of the situation is apparent, with agroindustrial firms even starting to ask themselves whether contracts with large farms are necessary and best.     

Measuring the production efficiency of alternative land tenure contracts in a mixed crop-livestock system in Ethiopia

In this paper, we test the hypothesis that land held under varying configurations of property rights will be farmed at different levels of production efficiency. Production data were collected from 477 plots in a fairly productive, mixed fanning system in the Ethiopian highlands. Interspatial measures of total factor productivity, based on the Divisia index, were used to measure the relative production efficiency of three informal and less secure land contracts (rented, share-cropped and borrowed) relative to lands held under formal contract witli the Ethiopian government. Although the informally-contracted lands are farmed 10-16% less efficiently, the analysis indicates that farmers of such lands actually apply inputs more, rather than less, intensively (i.e., more inputs per unit of land). The gap in total factor productivity thus results from the inferior quality of inputs (or lack of skills in applying them) rather than a lack of incentive to allocate inputs to mixed crop-livestock farming. For this reason we find no empirical basis to support the hypothesis that land tenure is a constraint to agricultural productivity.     

Inefficiency due to tenancy protection: a new tenure problem in Taiwan

Fixed-rent tenancy was traditionally regarded as equally efficient as owner-cultivators. The counter-example is, however, presented here. Specifically, tenants with fixed-rent contracts and well protected by tenancy regulations may, in the long run, turn out to be less efficient than other farmers (e.g., owner-cultivators and informal tenants), particularly when they do not heavily depend on farm revenue as major source of family income. On the other hand, tenants who are not benefited from tenancy regulations might not be less efficient than owner-cultivators. The underlying implication is tenancy reform is not a panacea for improving farming efficiency; it may result in many negative effects in the long run.     

Investment in soil conservation in northern Ethiopia: the role of land tenure security and public programs

A double hurdle statistical analysis of 250 farms in the Tigray region of Ethiopia reveals different causal factors for soil conservation adoption versus intensity of use. Farmers' reasons for adopting soil conservation measures vary sharply between stone terraces and soil bunds. Long‐term investments in stone terraces were associated with secure land tenure, labour availability, proximity to the farmstead and learning opportunities via the existence of local food‐for‐work (FFW) projects. By contrast, short‐term investments in soil bunds were strongly linked to insecure land tenure and the absence of local food‐for‐work projects. Public conservation campaigns on private plots reduced adoption of both stone terraces and soil bunds. Whereas capacity factors largely influenced the adoption decision, expected returns carried more influence for the intensity of stone terrace adoption (measured as metres of terrace per hectare). More stone terracing was built where fertile but erodible silty soils in higher rainfall areas offered valuable yield benefits. Intensity of terracing was also greater in remote villages where limited off‐farm employment opportunities reduced construction costs. These results highlight the importance of the right kind of public interventions. Direct public involvement in constructing soil conservation structures on private lands appears to undermine incentives for private conservation investments. When done on public lands, however, public conservation activities may encourage private soil conservation by example. Secure land tenure rights clearly reinforce private incentives to make long‐term investments in soil conservation.

Tenure security, resource poverty, public programs, and household plot-level conservation investments in the highlands of northern Ethiopia

Land degradation poses a serious problem for the livelihoods of rural producers. Furthermore, there is rarely enough private investment taking place to commensurate the scale of the problem. This article examines the role of tenure insecurity, resource poverty, risk and time preferences, and community‐led land conservation on differentiated patterns of household investment in land conservation in northern Ethiopia. We control for biophysical, household characteristics, market access conditions, and village level factors. Investments in soil bunds and stone terraces are specifically studied so as to capture the link between these various factors and the durability of conservation investments. We introduce the distinction between the determinants of the decision to invest and how much to invest in conservation. Regression results show that publicly led conservation programs seem to significantly stimulate private investment. A host of plot‐level variables and household perceptions of returns on conservation investments, expressed in terms of perceived improvements in land quality and increased crop yields, were found to be critical to the decision to invest and intensify soil conservation. The evidence on the significance of households' attitudes toward risk aversion suggests the important role of risk and the household's risk‐bearing capacity in the decision to intensify conservation measures. At the same time, tenure security indicators and households' resource endowments (resource poverty) had weaker effects in increasing willingness to invest and the level of investment made. The policy implications of these results point to the importance of agricultural research and extension efforts that target technologies which reduce household risk and poverty while enabling sustainable investments in conservation measures by individual households.     

Chinese land policies and farmers’ adoption of organic fertilizer for saline soils

Soil salinization has become a global concern and poses a great threat to food production and sustainable land use. Land use policies are the main driver of saline soil farmland use in ecosystems. This paper proposes a theoretical framework for analyzing how saline soil farmland use is affected by land use practices of individual farm households. An empirical study, using an ordered probit model, was conducted based on questionnaire responses from farm households in 8 towns and 14 villages in eco-fragile areas in Shandong, Jilin and Xinjiang provinces. The results suggest that land tenure, state systems agricultural support, characteristics of a field parcel and characteristics of the farm households have different influences on farmer's land use in three regions. The adoption of organic fertilizer by individual households is constrained by the lack of stability and integrity in land tenure. Furthermore, the parcel of a field is generally small, sparsely distributed and often fragmented, which increases costs. Even subsidizing organic fertilizer does not necessarily help in its adoption. Given these challenges, this study makes recommendations for different regions that may promote the adoption of improved saline soil farmland cultivation methods by farmers.     

Reverse tenancy in Romania: Actors’ rationales and equity outcomes

Following the implementation of the land reform in the 1990s, land rentals have developed in Romania, mainly in a reverse tenancy configuration. The paper provides an analysis of contractual practices in this configuration, based on empirical data collected through intensive field work in Transylvania. The paper depicts the reverse tenancy configuration and the conditions of its emergence in Romania, following the implementation of transition reforms in the agricultural sector. Characterizing the negotiation and enforcement of contracts in this configuration shows that in a situation where no effective enforcement mechanism is available, the market structure is such that tenants can choose “very incomplete” contracts or default on their contractual obligations. The analysis of the landowners’ perspective, taking into account their perception of the contractual relationship, contributes to explain why contractual practices persist in this context. The article concludes with a discussion, from a policy perspective, of the equity-enhancing role of the land lease market in such a reverse tenancy configuration.     

Land tenure security and its implications for investments to urban agriculture in Soweto,South Africa

Land tenure regime is considered one of the most crucial assets determining viability of urban agriculture, especially in terms of investments. Many authors have built on traditional agricultural theory that only land ownership and (formal) secure land tenure can incite investments into farming, thus stressing the need of secure land tenure for more prosperous urban agriculture. However, these statements are often built on weak or nonexistent empirical evidence. This research aims to contribute to the discussion on land tenure for urban agriculture by mixed-method exploration of the above-mentioned theory. Additionally, we propose a farming investment index which measures the level of investments by using non-monetary information obtained from respondents. The results of our study show that land tenure security for urban farmers is often seen as a rather narrow concept, focusing only on legal tenure security but omitting its other dimensions such as perceived and de facto tenure security. Nevertheless, all three dimensions of tenure security positively influence investments to urban agriculture.     

Farm productivity in Rwanda: effects of farm size,erosion, and soil conservation investments

This paper examines the effects of farm size, soil erosion, and soil conservation investments on land and labor productivity and allocative efficiency in Rwanda. There were several key results. First, there is a strong inverse relationship between farm size and land productivity, and the opposite for labor productivity. For smaller farms, there is evidence of allocative inefficiency in use of land and labor, probably due to factor market access constraints. Second, farms with greater investment in soil conservation have much better land productivity than average. Those with very eroded soils do much worse than average. Smaller farms are not more eroded than larger farms, but have twice the soil conservation investments. Third, land productivity benefits substantially from perennial cash crops, and the gains to shifting to cash crops are highest for those with low erosion and high use of fertilizer and organic matter. Program and policy effort to encourage and enable farmers to make soil conservation investments, to use fertilizer and organic matter, and to participate in cash cropping of perennials will have big payoffs in productivity. Land markets that allow smaller farmers to buy land could also increase aggregate productivity.     

Farm size and the determinants of productive efficiency in the Brazilian Center-West

This paper explores the determinants of technical efficiency, and the relationship between farm size and efficiency, in the Center-West of Brazil. This is the region where agricultural production and total factor productivity have grown the fastest since 1970. It is also a region characterised by unusually large farms. Technical efficiency is studied with Data Envelopment Analysis and county level data disaggregated by farm size and type of land tenure. The efficiency measure is regressed on a set of explanatory variables which includes farm size, type of land tenure, composition of output, access to institutions and indicators of technology and input usage. The relationship between farm size and efficiency is found to be non-linear, with efficiency first falling and then rising with size. Type of land tenure, access to institutions and markets, and modern inputs are found to be important determinants of the differences in efficiency across farms.     

Evolution of the Amazonian frontier: Land values in Rondônia, Brazil

Patterns in property values provide strong signals about the future and sustainability of land use. This paper analyzes the determinants of land value in an Amazonian frontier settlement. We estimate hedonic price functions to identify factors that affect the value of farm properties in the western Brazilian Amazon. Distance to market explains nearly one-third of the variation in farm value, as predicted by the von Thünen model. After controlling for location relative to the central market and for municipality, we find that investment in the farms (as reflected in the stocking rate of pastures and the establishment of home gardens) has the next largest impact on land value. The value per hectare of land is negatively related to total lot size, suggesting that any economies of scale are outweighed by the cost of accessing remote corners of large properties. We do not find that land values are related to available measures of biophysical factors or to historic or current land use. Our results do not identify any premium for forest cover or for land uses considered to be more sustainable than pasture on the property itself. However, farm values are affected by neighboring land cover, specifically, the extent of barren land. Thus, local knowledge of factors contributing to future productivity, as summarized in land values, confirms that soil exhaustion can lead to a general decline in property values, while investments in a property both as a homestead and as a farm can help sustain frontier settlements.     

Policy instruments for sustainable land management: the case of highland smallholders in Ethiopia

Degradation of land continues to pose a threat to future food production potential in many developing economies. Various approaches, mainly based on command‐and‐control policies, have been tried (with limited success) in the past to encourage adoption of erosion‐control practices by farm households. High transactions costs and negative distributional impacts on the welfare of the poor limit the usefulness of standards and taxes for soil and water conservation. One innovative approach is the use of interlinked contracts which create positive incentives for land conservation. This study analyses the social efficiency of such policies for erosion‐control in the Ethiopian highlands using a non‐separable farm household model. Incentive contracts linked with conservation seem to be promising approaches for sustainable resource use in poor rural economies. This may suggest that conservation programs should give greater consideration to better fine‐tuning and mix of policies that help achieve both economic and environmental objectives.
