Drylands (arid and semi-arid regions) are important regions in the world; they have been disregarded and considered poor undeveloped regions due to their ecological limitations. Farmers in these regions tend towards diversification of production systems in order to achieve livelihood security, and this phenomenon has not been extensively studied. The objective of this study was to create a typology of the production systems present in the Mexican north central drylands, using variables related to production, socioeconomics, and social capital. 1044 interviews were conducted in the semi-arid region of north central Mexico. Analysis of the data allowed for the observation of nine types of production systems distributed in three groups: Subsistence, commercial, and off-farm income systems. The differences observed within these systems are due to generational gaps, gender differences, market orientation, and social capital. It can be concluded that the diversification of the dryland production systems allows for an understanding of why generic public policies have failed to mitigate poverty in these regions. The implications of the study refer to the reconfiguration of Mexican policies for the development of the drylands.

Agriculture sector is more vulnerable to climate change than other sectors of the economy as climate change is expected to cause higher variability in rainfall pattern, general reduction in precipitation in the arid and semi-arid regions and increase in the frequency of extreme events such as drought, floods, heat and frost. Agriculture production systems, therefore, have to cope with more variability in river water flows and temperature regimes, making food security susceptible to these variation. The less privileged people/farmers who are often located in the marginal production areas such as rainfed, coastal, and mountenace, are likely to be affected more by climate variability whether drought or floods, heat or frost. These changes in climate enhance the risk of crop failures and livestock morality thereby causing financial and economic losses and the risk of food insecurity.

ABSTRACT Beet and lettuce are industrial vegetable crops valued for their high mineral, vitamin and fiber contents and for their additional health benefits. These crops are usually grown in intercrops in family production systems in a sustainable manner in semi-arid regions. This work aimed to evaluate the effects of incorporating different levels of hairy woodrose, as a green manure, on the agro-economic sustainability indicators of lettuce-beet intercrops, planted in different spatial arrangements and involving two successive croppings. The experimental design was a randomized complete blocks with treatments arranged in a 4 x 3 factorial scheme, corresponding to four hairy woodrose levels incorporated into the soil (6, 19, 32 and 45 t ha-1, dry basis) and three spatial arrangements between the component crops (2:2, 3:3 and 4:4), with four replications. The optimized agroeconomic performance of lettuce-beet intercropping was achieved with the incorporation of approximately 35.30 t ha-1 hairy woodrose. The lettuce crop contributed significantly to the productivity efficiency and sustainability of the intercropping with beet, compared to the single vegetable crops. The spatial arrangements between component crops did not affect the agroeconomic performance of the lettuce intercropped with beet.

Family farmers of semi-arid regions are especially vulnerable to climate change, due to the reliance on rain-fed production systems and the limited capacity to cope and adapt to impacts. The Brazilian Food Acquisition Program (PAA), as an example of a food procurement program that also functions as a food-based safety net for vulnerable populations, is analysed in a context of extreme drought in the Cariri region (Ceará state, Brazil).  Limitations that prevent the full range of potential PAA benefits are examined as perceived by institutional actors involved with the program, while measures to foster the full potential positive impacts on beneficiaries are discussed. Findings indicate that more consideration of the importance of governance and institutional factors on functioning of food acquisition programs, as well as the importance of the role of climate change on this equation, are essential for program sustainability, especially in a scenario of climate change.

Hater resource managers in semi-arid regions are faced with some unique problems. The wide variations in precipitation and stream flows in semi-arid regions increase man's dependence on the ground water resource for an ample and reliable supply of water. Proper management of the ground water resource is absolutely essential to the economic well being of semi-arid regions. Historians have discovered the remains of vanished advanced civilizations based on irrigated agriculture which were ignorant of the importance of proper ground water resource management. In the United States a great deal of effort is presently being expended in the study and control of toxic discharges to the ground water resource. What many public policy makers fail to understand is that the potential loss to society resulting from the mineralization of the ground water resource is potentially much greater than the loss caused by toxic wastes discharges, particularly in developing countries. Appropriations for ground water resource management studies in developed countries such as the United States are presently much less than those for toxic wastes management and should be increased. It is the reponsibility of the water resource professional to emphasize to public policy makers the importance of ground water resource management. Applications of ground water resource management models in the semi-arid Central Valley of California are presented. The results demonstrate the need for proper ground water resource management practices in semi-arid regions and the use of ground water management models as a valuable tool for the water resource manager.
