More than five billion metric tons of agricultural residues are produced annually worldwide. Despite having multiple uses and significant potential to augment crop livestock production, a large share is burned, especially in Asian countries. This unsustainable practice causes tremendous air pollution health hazards while restricting soil nutrient recycling. In this review, we examine the economic rationale for residue management. The sustainability utilization determined by several factors,...
Abstract This paper investigates the relationship between poverty and lack of access to adequate safe water in rural Malawi. Data used analysis was collected from a survey covering 1,651 randomly selected households. We use Canonical Correlation Analysis (CCA) as distinct technique for understanding poverty–rural nexus. CCA results indicate that context low income expenditure is positively correlated with water. Integrated Rural Water Resources Management (IRWM) interventions are therefore...
Methodological advances for use with large-n datasets hold the promise of transforming ways that agricultural landscapes are described, understood, and managed. Nevertheless, most countries lack comprehensive characterization data crop production systems this constrains application emerging analytical methods. New required routinely collected, representative, topically robust through surveys efficiently deployed at scale, especially in smallholder-dominated where heterogeneity is common....
Games are meant to be fun, yet economists have successfully developed games that less fun and understood by participants especially in developing countries.

This study examines the correlational relationship between historical playing of indigenous strategic board games (also called mancala) and socio-economic complexity African ethnic groups as well incidence entrepreneurial pursuits. Anthropology literature suggests that these may be associated with groups—the so-called in culture hypothesis. I revisit this hypothesis better data motivated by anecdotal evidence, introduce a contemporary hypothesis, origins entrepreneurship hypothesis—that...
Adjusting crop planting dates and variety durations is emerging as a crucial climate change adaptation strategy for many cereal systems. Such strategies include harmonizing with the onset of rainy season or at specific recommended calendar dates. Evaluations these mostly consider yield variability, but focus less on financial risks associated different importance risk aversion behaviour farmers in their decision to adopt strategies. Here, we present novel framework that uses computational...
Abstract A stylized fact of African agriculture is that crop responses to inorganic fertilizer application derived from experimental studies are often substantially greater than those observational (e.g. surveys and administrative data). Recent debates on relative costs benefits expensive farm input subsidy programs in Africa, have raised the importance reconciling these estimates. Beyond mean response differences, this paper argues for including parameter uncertainty heterogeneity arising...
<title>Abstract</title> Groundwater irrigation supports over 40% of global crop production and stabilizes yields amidst climatic change. Yet, over-abstraction can cause water scarcity, disrupt ecosystems, increase greenhouse gas emissions. Governments international financial institutions have made significant investments in sustainable groundwater but require enhanced spatial targeting to impact. In response, this study employs an agro-hydrological machine-learning approach analyze patterns...
Malawi's export earnings are dominated by tobacco, accounting for over 60% of earnings. The demand an alternative commodity, pigeon pea, has been rising the past decade, especially from India. In addition to their potential, pea is effective cover crop protect soil heath and productivity in dry season. They mostly grown southern region on very small farms, however, there opportunities expansion into central given existence larger farms agroecological suitability crop. Currently, social norms...
Abstract Should a typical developing country invest more in agriculture or education? At what stage of development is it optimal to each these sectors? These are important questions that governments countries grapple with when designing investment plans. In this paper, I propose soil–human capital conceptual framework and use explain estimates agricultural returns schooling Malawi. panel survey data for Malawi rely on the exogenous education policy changes spatial variation access identify...
Are spatially specific agricultural input use recommendations more profitable to smallholder farmers than broad recommendations? This paper provides a theoretical and empirical modeling procedure for determining the optimal spatial scale at which researchers can make soil fertility recommendations. Theoretically, of Bayesian decision theory in economic optimization model allows complete characterization posterior distribution functions profits thereby taking into account heterogeneity...
This paper introduces two important extensions to the uncentered correlation metric, commonly used metric proposed by Jaffe [1986. “Technological Opportunity and Spillovers of R & D: Evidence From Firms’ Patents, Profits, Market Value.” The American Economic Review 76 (5): 984–1001] for analyzing research spillovers across firms or countries. First, it is shown that can be displayed graphically using biplot, a graphical display two-dimensional approximation any multidimensional matrix....

Every government grapples with questions annually when designing national budget. In this paper, I provide estimates agricultural returns schooling Malawi- evidence such implies complex non-separable decision process answer the first question. While large economics literature has documented effects on incomes, are potentially biased because unobserved...
A stylized fact of African agriculture is that experimentally derived crop responses to inorganic fertilizer application are substantially greater than those from observational studies e.g., farm surveys and administrative data. The continuing divergence between experimental reported in the literature coupled with recent debates on costs benefits re-surging input subsidy programs Africa have ignited old problem reconciling these estimates. This paper argues progress closing gaps has been...
